Electronic stability control

ESC with understeer control

and traction control

Electronic stability control ESC
This system helps you to keep control

of the vehicle in critical driving condi-

tions (avoiding an obstacle, loss of grip

on a bend, etc.).

Operating principle
A sensor in the steering wheel detects

the direction selected by the driver.
Other sensors throughout the vehicle

measure the actual direction.
The system compares driver input to

the actual trajectory of the vehicle and

corrects the trajectory if necessary by

controlling the braking of certain wheels

and/or engine power. In the event that

the system is engaged, indicator light



flashes on the instrument panel.

Understeer control
This system optimises the action of the

ESC in the case of pronounced under-

steer (loss of front axle road holding).

Traction control
This system helps to limit wheelspin of

the drive wheels and to control the ve-

hicle when pulling away accelerating or

decelerating.
Operating principle
Using the wheel sensors, the system

measures and compares the speed of

the drive wheels at all times and slows

down their over-rotation. If a wheel is

starting to slip, the system brakes au-

tomatically until the drive supplied be-

comes compatible with the level of grip

under the wheel again.

The system also adjusts the engine

speed to the grip available under the

wheels, independently of the pressure

exerted on the accelerator pedal.

Operating faults
When the system detects an operat-

ing fault the message “Check ESC” and

warning light

and



appear

on the instrument panel.

In this case, the ESC and traction con-

trol system are deactivated. Consult an

authorised dealer.

2.33

DRIVING CORRECTION DEVICES AND AIDS

(3/4)

The traction control system offers ad-

ditional safety. It is recommended that

you do not drive with the function di-

sabled. Correct this as soon as pos-

sible by pressing the switch 1 again.

Note: The function is reactivated auto-

matically when the ignition is switched

on or when a speed of approximately

24 mph (40 km/h) is exceeded.

Emergency brake assist

This system supplements the ABS

and helps reduce vehicle stopping dis-

tances.
Operating principle

The system detects an emergency

braking situation. In this case, the brak-

ing assistance immediately develops

maximum power and may trigger ABS

regulation. ABS braking is maintained

as long as the brake pedal is not re-

leased.
Hazard warning lights illumination

Depending on the vehicle, these may

light up in the event of sudden decel-

eration.

These functions are an ad-

ditional aid in the event of

critical driving conditions,

enabling the vehicle behav-

iour to be adapted to suit the driving

conditions.
However, the functions do not take

the place of the driver. They do

not increase the vehicle’s limits

and should not encourage you

to drive more quickly. Therefore,

they can under no circumstances

replace the vigilance or responsibil-

ity of the driver when manoeuvring

the vehicle (the driver must always

be ready for sudden incidents which

may occur when driving).

Deactivating the function

(depending on vehicle)
In some situations (driving on very wet

ground: snow, mud, etc. or driving with

snow chains fitted), the system may

reduce the engine output to limit wheel-

spin. If this is not required, it is possible

to deactivate the function by pressing

switch 1.

The message “ESC off” is displayed on

the instrument panel to inform you.

2.34

DRIVING CORRECTION DEVICES AND AIDS

(4/4)

Hill start assistance

Depending on the gradient of the in-

cline, this system assists the driver

when starting on a hill. It prevents the

vehicle from rolling backwards by au-

tomatically applying the brakes when

the driver lifts his/her foot off the brake

pedal to depress the accelerator pedal.

System operation
It only operates when the gear lever is

in a position other than neutral (other

than N or P for automatic transmis-

sions) and the vehicle is completely

stationary (brake pedal depressed)

The system holds the vehicle for ap-

proximately 2 seconds. The brakes are

then released (the vehicle will move ac-

cording to the slope).

The hill start assistance

system cannot completely

prevent the vehicle from

rolling backwards in all sit-

uations (extremely steep gradients,

etc.).

In all cases, the driver may depress

the brake pedal to prevent the vehi-

cle from rolling backwards.

The hill start assistance function

should not be used for prolonged

stops: use the brake pedal.

This function is not designed to im-

mobilise the vehicle permanently.

If necessary, use the brake pedal to

stop the vehicle.

The driver must remain particularly

vigilant when driving on slippery or

low-grip surfaces and/or on hills.

Risk of serious injury.

2.35

Mode selector

Depending on the road conditions, turn-

ing the selector 1 enables the following

modes to be selected:
– AUTO ;
– 2WD ;
– 4WD Lock.

“AUTO” mode

To activate this mode, turn selector 1 to

the “AUTO” position.

Operating principle
“AUTO” mode automatically distributes

the engine torque between the front and

rear axles according to the road condi-

tions and the vehicle speed. This po-

sition optimises roadholding. Use this

mode on any type of road (dry, snow-

covered, slippery, etc.) or when towing

(trailer or caravan).

The warning light



on the instru-

ment panel will come on.

TRANSMISSION: 4-wheel drive (4WD)

(1/4)

“2WD” mode

To activate this mode, turn the selec-

tor 1 to the “2WD” position. The warn-

ing light

‘

on the instrument panel

will come on.

Operating principle
The “2WD” mode uses the front wheels

only. Use this mode on dry roads with

good grip.
To deactivate this mode, turn the selec-

tor 1 to the “AUTO” position. Warning

light

‘

goes out on the instrument

panel.

Remember that driving a vehicle off-

road is very different to driving it on

the road.
To make the most of your vehicle

in an off-road situation, we recom-

mend that you are trained to drive a

4x4 (4WD) vehicle.
The safety of both you and your

passengers is your responsibility,

and depends on your skill and the

care you take when driving off-road.

2.36

TRANSMISSION: 4-wheel drive (4WD)

(2/4)

This problem may be resolved by

changing the tyres. Always use four

identical tyres (same brand, profile,

etc.) and with similar wear.
In the event of excessive wheelspin, the

mechanical components may overheat.
If this happens:

– at first, the

’

warning light

comes on. “4WD Lock” mode is still

active – however, we recommend

that you stop as soon as possible to

allow the system to cool down (until

the warning light goes out);

– if the wheels still spin, the system au-

tomatically switches to “2WD” mode

to protect the mechanical compo-

nents.
The message “4WD overheating” is

displayed on the instrument panel.

The mode cannot be changed while

the message is displayed.

Note: If the vehicle speed exceeds

approximately 24.8 mph (40 km/h) in

“4WD Lock” mode, the system auto-

matically switches back to “AUTO”

mode.

The

’

warning light goes out and

the



warning light comes on.

Special features of the

4-wheel drive transmission

The vehicle may make more noise when

the “AUTO” or “4WD Lock” modes are

activated. This is normal. If the system

detects a difference in the dimensions

of the front and rear wheels (eg. un-

derinflation, severe wear on an axle),

the system automatically switches to

“2WD” mode.
The message “4WD unavailable unsuit-

able tyres” is displayed on the instru-

ment panel. Drive as soon as possible

at a moderate speed to an approved

dealer.

“4WD Lock” mode

To activate this mode, turn selector 1 to

the “4WD Lock” position. The selector

the returns to the “AUTO” position. The

’

indicator light will light up on the

instrument panel.

Operating principle
“4WD Lock” mode distributes the

engine torque between the front and

rear axles in order to optimise the per-

formance capacity of the vehicle in off-

road situations. This mode should only

be used in extreme driving conditions

(mud, steep slopes, sand).

To deactivate this mode, turn selector 1

to the “4WD Lock” position again. The

warning light goes out on the instru-

ment panel.

2.37

TRANSMISSION: 4-wheel drive (4WD)

(3/4)

Electronic stability program and

traction control when driving off-

road
When driving on soft ground (sand,

mud, deep snow), we recommend that

you deactivate the ESC function by

pressing the “ESC” switch.
In this case, only individual wheel brak-

ing remains active. This function ap-

plies the brake to any wheel that is slip-

ping, allowing the engine torque to be

transferred to the wheels with the most

grip. This is particularly useful when

crossing a bridge.
All the ESC functions will be reacti-

vated when the vehicle speed reaches

approximately 31 mph (50 km/h)

(24.8 mph [40 km/h] in 4WD Lock

mode), when the engine is restarted

or when the “ESC” switch is pressed

again.

Operating faults

If the system detects an operating fault,

it automatically switches to “2WD”

mode. The message “Check 4WD” is

displayed on the instrument panel, and

the

‘

and

warning lights

come on.
Drive as soon as possible at a moder-

ate speed to an approved dealer.
For certain operating faults, the system

may not be able to switch to “2WD” or

"4WD Lock” mode. “AUTO” mode re-

mains active.
Contact an approved dealer as soon as

possible.

After stopping the engine, the system

may take up to five minutes to cool

down.

If the system detects excessive wheel-

spin on the front wheels, it adapts the

engine to run in a way that reduces

wheelspin.

Anti-lock braking in LOCK mode
When “4WD Lock” mode is active, the

ABS switches to off-road mode. In this

case, the wheels may lock intermit-

tently to achieve better grip, thus reduc-

ing braking distances on soft ground.

When this mode is active:

– the vehicle’s manoeuvrability is lim-

ited during braking. This operating

mode is therefore not recommended

in very low-grip conditions (eg. ice).

– there may be some noise. This is

normal, and does not indicate an op-

erating fault.

2.38

TRANSMISSION: 4-wheel drive (4WD)

(4/4)

All-wheel drive system
– Irrespective of the mode selected, do not start the engine if one or more wheels are not in contact with the ground

(eg. when the vehicle is on a jack or roller bench).

– Do not turn the mode selector when cornering, reversing or if the wheels are spinning excessively. Only select the

“2WD”, “AUTO” or “4WD Lock” mode when the vehicle is being driven in a straight line.

– Only use tyres which meet the required specifications.
– “4WD Lock” mode is exclusively reserved for driving off-road. The use of this mode in any other conditions may adversely

affect the vehicle’s manoeuvrability and damage its mechanical components.

– Always ensure tyres with identical specifications are fitted to all four wheels (brand, size, structure, wear etc.). Fitting tyres

of different sizes to the front and rear wheels and/or left and right wheels may have serious consequences for the tyres,

gearbox, transfer gearbox and the rear differential pinions.

2.39

ACTIVE EMERGENCY BRAKING

(1/11)

Active emergency braking

The system has two types. Depending

on the vehicle, one of the two systems

is equipped in the vehicle.
- System A
- System B

This function is an addi-

tional driving aid. This func-

tion is not under any circum-

stances intended to replace

the due care and attention of the

driver, who should at all times be

in control of the vehicle.

System A is composed of the radar

sensor 1 and the front camera 2.
You can find that your vehicle is with the

system A from the shape of the front

camera area.
If your vehicle is equipped with system

A, please refer to the information on

“System A” in following pages.
Note: The radar sensor 1 is located

behind the front bumper. It’s difficult to

identify the presence of the radar.

System B is using the radar-camera

sensor 3.
You can find that your vehicle is with the

system B from the shape of the radar-

camera sensor area.
If your vehicle is equipped with system

B, please refer to the information on

“System B” in following pages.

2.40

Activating or deactivating the

system

For vehicles fitted with a navigation

system
On the multifunction screen 5, select

the “Vehicle” menu, “Driving assist-

ance”, and “Active braking”, and then

choose “ON” or “OFF”.

ACTIVE EMERGENCY BRAKING

(2/11)

You can access menu “Driving as-

sistance” directly from button 6



Operation

While driving (at speeds of between 20

and 85 mph (30 and 140 km/h)), if there

is a risk of collision with the vehicle in

front, the warning light 4 will be dis-

played on the instrument panel in red,

alongside a beep.
If the driver depresses the brake pedal

and the system still detects a risk of

collision, the brake force is increased. If

the driver fails to react following an alert

of an imminent collision, the system ac-

tivates the brakes.

System A

Operating principle

Using the radar sensor, the system cal-

culates the distance separating the ve-

hicle from the one in front and alerts the

driver if there is a risk of a front-end col-

lision. The driver can then brake the ve-

hicle to limit the damage arising from a

collision.
Note: make sure that the radar sensor 1

is not obscured (by dirt, mud, snow etc.

or by the fitting of accessories such as

bullbars).

2.41

System A (continued)

For vehicle not fitted with a

navigation system
– With the vehicle at a standstill, press

and hold the switch 7 OK to access

the settings menu,

– repeatedly press the control 8 up or

down until you reach the “Driving as-

sistance” menu. Press the switch 7

OK;

– repeatedly press control 8up or down

until you reach the “Active braking”

menu, then press the switch 7 OK.

ACTIVE EMERGENCY BRAKING

(3/11)

Operating faults

When the system detects an operating

fault, the



warning light lights up

on the instrument panel, with the mes-

sage “Active braking disconnected”.
There are two possibilities:
– the system is temporarily disrupted

(for example: radar obscured by

dirt, mud, snow etc.). In this case,

park the vehicle and switch off the

engine. Clean the detection zone of

the radar. When you next start the

engine, the warning light and the

message go out

– if this is not the case, this may arise

from another cause; contact an

Approved Dealer.

Consult an approved dealer.

Press the switch 7 OK again to activate

or deactivate the function:

function activated

The warning light



is displayed on

the instrument panel when the system

is deactivated. This system is reacti-

vated each time the ignition is switched

on.

Conditions for non-activation

of the system

The system cannot be activated:
– when the gear lever is in neutral;
– when the parking brake is activated;
– while cornering.
– For 4-wheel drive vehicles, when

Electronic Stability Programme

(ESC) with understeer and trac-

tion control are deactivated (please

see “Electronic Stability Programme

(ESC) with understeer and trac-

tion control” above). Warning light



comes on.

The system A only detects vehicles

driving in the same direction of traf-

fic. The system cannot detect mo-

torcycles because of the difficulty in

forecasting their trajectory.

2.42

ACTIVE EMERGENCY BRAKING

(4/11)

Active emergency braking

This function is an additional driving aid. This function is not under any circumstances intended to replace the due care

and attention of the driver, who should at all times be in control of the vehicle. The triggering of this function may be

delayed or prevented when the system detects clear signs of control of the vehicle by the driver (action on the steer-

ing wheel, pedals etc.).

System servicing/repairs
– In the event of an impact, the radar-camera or radar alignment may be changed, and its operation may consequently be af-

fected. Deactivate the function, then consult an authorised dealer.

– Any work in the area where the radar-camera or radar are located (repairs, replacements, windscreen modifications etc.)

must be carried out by a qualified professional.

– Fitting accessories which may block the radar is prohibited (bull bars etc.).
Only an authorised dealer is qualified to service the system.

In the event of system disturbance
Some conditions can disturb or damage the operation of the system, such as:
– a complex environment (metal bridge, tunnel etc.);
– poor weather conditions (snow, hail, black ice etc.);
Risk of inadvertent braking.

2.43

ACTIVE EMERGENCY BRAKING

(5/11)

Limitation of the system operation
– The system will only respond to vehicles which are moving or which have been sensed as moving.
– The radar area should be kept clean and free of any modifications in order to ensure the proper operation of the

system.

– The system cannot respond to small vehicles such as motorbikes, bicycles or pedestrians as effectively as to other vehicles.
– The system may not operate properly when the road surface is slippery (rain, snow, black ice etc.).

Deactivating the function
You must disable the function if:
–  the brake lights are not functioning;
–  the front of the vehicle has undergone an impact or been damaged;
–  the vehicle is being towed (breakdowns);

Halting the function
You can halt the active braking function at any time by tapping the accelerator pedal or by turning the steering wheel in a avoid-

ance manoeuvre.
In the event of the system behaving abnormally, deactivate it and consult an authorised dealer.

2.44

ACTIVE EMERGENCY BRAKING

(6/11)

System B

Operating principle

Using information from the radar-cam-

era, the system calculates the distance

which separates it from the vehicle in

front and the surrounding pedestrians.
It notifies the driver if there is a risk of

head-on collision. The driver can then

brake the vehicle to limit the damage

arising from a collision.
Note: make sure the windscreen is not

obscured (dirt, mud, snow, condensa-

tion etc.).

This function is an addi-

tional driving aid. This func-

tion is not under any circum-

stances intended to replace

the due care and attention of the

driver, who should at all times be

in control of the vehicle.

This system applies maximum

braking to the vehicle
For safety reasons, always wear

your seat belt when travelling in

your vehicle and make sure that it

is loaded so that no items can be

thrown forward and hit the occu-

pants.

Detection of pedestrians

Operation
When driving (speed between

about 4.2 mph (7 km/h) and 36 mph

(60 km/h)), if there is a risk of impact

with a pedestrian, the indicator 9 is dis-

played in red on the instrument panel

and accompanied by a beep.
When the impact is imminent, the

system activates the braking.
The system can apply maximum brak-

ing.

2.45

ACTIVE EMERGENCY BRAKING

(7/11)

System B (continued)

Detection of vehicles

Operation
When driving (speed between about

4.34 and 99.2 mph (7 and 160 km/h)), if

there is a risk of collision with the vehi-

cle in front, the system:
– warns you of a collision risk:

The

indicator

4 is displayed in red

on the instrument panel and accom-

panied by a beep.
If the driver depresses the brake

pedal and the system still detects a

risk of collision, the brake force is in-

creased.

– triggers braking:

if the driver fails to react following

the alert and collision becomes im-

minent.

You can interrupt braking at any

point by:

– tapping the accelerator pedal;

– turning the steering wheel in an

avoidance manoeuvre.

Special features
When the vehicle speed:
– is less than 27.9 mph (45 km/h) ap-

proximately, the warning and brak-

ing are activated at the same time;

– is between about 27.9 mph

(45 km/h) and 48 mph (80 km/h)

approximately, the warning is acti-

vated. Braking will only be triggered if

the vehicle preceding you is moving.

Braking is not activated for stationary

vehicles;

– is between about 48 mph (80 km/h)

and 99.2 mph (160 km/h), the warn-

ing and braking are only triggered if

the vehicle preceding you is moving.

The warning and braking are not ac-

tivated for stationary vehicles;

– is above 99.2 mph (160 km/h), the

system is not active.

(9/11)

System B (continued)

Conditions for non-activation

of the system

The system cannot be activated:

– when the gear lever is in neutral;

– when the parking brake is activated;

– while cornering.
As a general rule, if the driver shows

signs of attention (action on the steering

wheel, pedals etc.), the system delays

its operation or does not activate.

Operating faults

When the system detects an operating

fault, the



warning light lights up

on the instrument panel, with the mes-

sage “Active braking disconnected”.
Consult an approved dealer.

Temporarily not available

When the system detects a tempo-

rary unavailability, the



warning

light lights up on the instrument panel

accompanied by the message “Active

braking: sensor blind” or, depending on

the vehicle, “Radar-camera: no visibil-

ity”.
The possible causes are:
– the system is temporarily blinded

(glare from the sun, dipped beam

headlights, bad weather conditions

etc.). The system will be operational

again when visibility conditions are

better.

– The system is temporarily disrupted

(for example: windscreen obscured

by dirt, ice, snow etc.). In this case,

park the vehicle and switch off the

engine. Clean the windscreen. When

you next start the engine, the warn-

ing light and the message go out.

– If this is not the case, this may arise

from another cause; contact an
