Dynamic cruise control "CRuISe"

this systems allows the vehicle's speed to be
maintained at a value set by the driver.
In addition it allows (when circumstances
permit) an inter-vehicle time that you have
selected to be maintained between your vehicle
and the one in front.

Principles of operation

using a radar with a range of about 100 metres,
located at the front of the vehicle, this system
detects a vehicle running in front of your
vehicle.
It automatically adapts the speed of your
vehicle to that of the vehicle in front.
If the vehicle in front is running more slowly,
the system progressively reduces the speed of
your vehicle using just engine braking (as if the
driver had pressed the "-" button).
If your vehicle is too close to, or approaching
too quickly the vehicle in front, the dynamic
cruise control is automatically deactivated.
the driver is then alerted by an audible signal,
accompanied by a message.
If the vehicle in front accelerates or changes
lane, the dynamic cruise control progressively
accelerates your vehicle to return to the
programmed speed.
If the driver operates a direction indicator to
overtake a slower vehicle, the dynamic cruise
control allows your vehicle to temporarily
approach the vehicle in front to assist the
overtaking manoeuvre, though never exceeding
the programmed speed.

Switching between the types of cruise control

If you want to use the "standard" cruise control,
it is possible to deactivate the dynamic cruise
control in the touch screen.
the cruise control selection thumbwheel must
be in the "CRuISe" position, otherwise the
choice will not be taken into account.

For more information on the Cruise
control, refer to the corresponding
section.

the state of the system is memorised on
switching off the ignition.

F Press the button

to change from
dynamic cruise
control to "standard"
cruise control and
vice-versa.

the dynamic cruise control operates
by day and at night, in fog or moderate
rainfall.

the system does not act on the braking
system, but works only with engine
braking.
the regulation range is limited: there will
no longer be any adjustment of speed if
the difference between the programmed
speed setting and the speed of the
vehicle in front becomes too great.

the selection of this system deactivates
the display of inter-vehicle time.

If the difference between the
programmed speed setting and the
speed of the vehicle in front is too
great, the speed cannot be adjusted:
the cruise control is automatically
deactivated.

181

Driving

308_en_Chap06_conduite_ed01-2016

the dynamic cruise control is switched on
manually, it requires that the speed of the
vehicle be between 25 mph (40 km/h) and
90 mph (150 km/h).

General points

the dynamic cruise control can be paused
manually with the control, or automatically:
-

by pressing the brake or clutch pedal,

in the event of operation of the eSC, for
safety reasons,

in the event of an action on the electric
parking brake control,

when an inter-vehicle time threshold is
reached (calculated according to the
relative speeds of your vehicle and the
vehicle in front and the inter-vehicle time
setting chosen),

when the distance between your vehicle
and the one in front becomes too small,

when the speed of the vehicle in front is
too low,

when the speed of your vehicle becomes
too low.

the dynamic cruise control cannot in any
circumstances replace the observation
of speed limits, nor the need for the
vigilance on the part of the driver.
It is recommended that you always keep
your feet close to the pedals.

the inter-vehicle time setting is
memorised when switching off the
ignition.

With a manual gearbox, third or fourth gear
(depending on engine) or higher must be
engaged.

With an automatic gearbox, second gear or
higher must be engaged.

If the cruise speed setting is above 90 mph
(150 km/h), the dynamic cruise control switches
to normal cruise control mode (without
automatic adjustment of the safety inter-vehicle
distance).

1. Select cruise control mode.
2. Set the current speed as the cruise speed

setting / Reduce the cruise speed setting.

3. Set the current speed as the cruise speed

setting / Increase the cruise speed setting.

4. Pause / resume cruise control.

Detection of a vehicle, at the limit of the range of the radar:
the system operates as a standard cruise control.

"SPeeD ADJuSteD"

Detection of a vehicle that is too close or running at a speed lower than your
vehicle's cruise speed setting.
the system uses engine braking to slow your vehicle (within a limit of 20 mph
(30 km/h)) and then hold it at the speed of the vehicle in front so as to observe the
programmed inter-vehicle time.
When automatically slowing down behind a vehicle, your true speed may be higher
than the "adjusted speed" displayed.

"SPeeD ADJuSteD"

When the adjusted speed reaches the limit of regulation (speed setting less than
20 mph (30 km/h)), the adjusted speed flashes together with the speed setting to
signal that automatic deactivation of the system is imminent.

"Cruise control
paused".

If the system exceeds the limit of speed adjustment possible by the system and in
the absence of any reaction by the driver (operation of the direction indicator, change
of lane, reduction of the speed of the vehicle), the system is automatically paused.
the display of the deactivation message is accompanied by an audible signal.

185

Driving

308_en_Chap06_conduite_ed01-2016

When the dynamic cruise control is
automatically paused, it can only be
reactivated when safe conditions are
restored. the message "Activation
not possible, conditions unsuitable"
is displayed while reactivation is not
possible.
When the conditions allow, it is
recommended that the function be
reactivated by pressing button 2 (Set+)
or 3 (Set-), which will make the current
speed of your vehicle the new cruise
speed setting, rather than by pressing
button 4 (on/pause) which reactivates
the cruise control using the old cruise
speed setting, which may be very
different from the current speed of your
vehicle.

the speed regulation range is limited to a
maximum difference of 20 mph (30 km/h)
between the speed setting and the speed of the
vehicle in front.
Above this, the system goes into pause if the
safe distance becomes too low.
the dynamic cruise control uses only engine
braking to slow the vehicle. Consequently the
vehicle loses speed slowly, as when releasing
the accelerator pedal.
the system is paused automatically:
-

if the vehicle in front slows down too much
or too suddenly, and the driver does not
brake,

if a vehicle comes between your vehicle
and the vehicle in front,

if the system does not slow the vehicle
enough to continue to maintain a safe
distance, for example when descending a
steep hill.

Limits of operation

As the radar's field of view is quite narrow, it is
possible that the system may not detect:

the cruise control does not take
account of:
-

stationary vehicles,

vehicles driving in the opposite
direction.

vehicles of reduced width, such as
motorcycles,

vehicles not running in the middle of the
lane,

vehicles entering a corner,

vehicles changing lane at the last moment.

In the event of a fault with the dynamic cruise
control, you are alerted by an audible signal
and display of the message message "Driving
aid functions fault".
Have the system checked by a PeugeOt
dealer or a qualified workshop.

When the cruise control is working, take
care if making a maintained press on
one of the cruise control programmed
speed modification buttons: this can
lead to a very quick change in the
speed of your vehicle.
Do not use the dynamic cruise control
on slippery surfaces or in heavy traffic.
When descending a steep hill, the
cruise control may not be able to
prevent the vehicle from exceeding the
programmed speed.
When ascending a steep hill or when
towing, it might not be possible to attain
or maintain the programmed speed.

Operating fault

the operation of the radar, located in
the front bumper, may be disturbed in
certain weather conditions, for example:
with accumulations of snow, ice,
mud, ...
Clean the front bumper, removing the
snow, mud, ...

the use of mats not approved by
PeugeOt may interfere with the
operation of the dynamic cruise control.
