4-1. Before driving

WARNING

●

Be careful not to change the shift posi-

tion with the accelerator pedal

depressed. Changing the shift posi-

tion to any positions other than P or N

may lead to unexpected rapid acceler-

ation of the vehicle that may cause an

accident and result in death or serious

injury.

After changing the shift position, make

sure to confirm the current shift posi-

tion displayed on the shift position indi-

cator inside the meter.

■

Brake pad wear

If any of the following situations occurs,

have the brake pads visually checked and

replaced by any authorized Lexus

retailer or Lexus authorized repairer, or

any reliable repairer as soon as possible.

●

If the brake pad wear limit of a brake

pad is found to have been exceeded

when visually checking the brake pads

for each wheel (for the brake pad wear

limit, refer to P.535)

●

If a warning message is displayed on

the multi-information display (only the

right-side pads can be detected)

Rotor damage may result if the pads are

not replaced when needed.

Moderate levels of the brake pad and

disc wear allow enhanced braking power.

As a result, the discs may wear more

quickly than conventional brake discs.

Therefore, when replacing the brake

pads, Lexus recommends that you also

have the thickness of the discs measured.

It is dangerous to drive the vehicle when

the wear limits of the brake pads and/or

those of the brake discs are exceeded.

■

When the vehicle is stopped

●

Do not depress the accelerator pedal

unnecessarily.

If the shift position is in any position

other than P or N, the vehicle may

accelerate suddenly and unexpect-

edly, causing an accident.

●

In order to prevent accidents due to

the vehicle rolling away, always keep

depressing the brake pedal while

stopped with the “READY” indicator is

illuminated, and apply the parking

brake as necessary.

●

If the vehicle is stopped on an incline,

in order to prevent accidents caused

by the vehicle rolling forward or back-

ward, always depress the brake pedal

and securely apply the parking brake

as needed.

●

Avoid revving or racing the engine.

Running the engine at high speed

while the vehicle is stopped may cause

the exhaust system to overheat, which

could result in a fire if combustible

material is nearby.

■

When the vehicle is parked

●

Do not leave glasses, cigarette lighters,

spray cans, or soft drink cans in the

vehicle when it is in the sun.

Doing so may result in the following:

• Gas may leak from a cigarette lighter

or spray can, and may lead to a fire.

• The temperature inside the vehicle

may cause the plastic lenses and plas-

tic material of glasses to deform or

crack.

• Soft drink cans may fracture, causing

the contents to spray over the interior

of the vehicle, and may also cause a

short circuit in the vehicle’s electrical

components.

4-1. Before driving

Driving

WARNING

●

Do not leave cigarette lighters in the

vehicle. If a cigarette lighter is in a

place such as the glove box or on the

floor, it may be lit accidentally when

luggage is loaded or the seat is

adjusted, causing a fire.

●

Do not attach adhesive discs to the

windshield or windows. Do not place

containers such as air fresheners on

the instrument panel or dashboard.

Adhesive discs or containers may act

as lenses, causing a fire in the vehicle.

●

Do not leave a door or window open if

the curved glass is coated with a

metallized film such as a silver-colored

one. Reflected sunlight may cause the

glass to act as a lens, causing a fire.

●

Always apply the parking brake, shift

the shift position to P, stop the hybrid

system and lock the vehicle.

Do not leave the vehicle unattended

while the “READY” indicator is illumi-

nated.

If the vehicle is parked with the shift

position in P but the parking brake is

not set, the vehicle may start to move,

possibly leading to an accident.

●

Do not touch the exhaust pipes while

the “READY” indicator is illuminated

or immediately after turning the hybrid

system off.

Doing so may cause burns.

■

When taking a nap in the vehicle

Always turn the hybrid system off. Other-

wise, if you accidentally move the shift

lever or depress the accelerator pedal,

this could cause an accident or fire due

to hybrid system overheating. Addition-

ally, if the vehicle is parked in a poorly

ventilated area, exhaust gases may col-

lect and enter the vehicle, leading to

death or a serious health hazard.

■

When braking

●

When the brakes are wet, drive more

cautiously.

Braking distance increases when the

brakes are wet, and this may cause one

side of the vehicle to brake differently

than the other side. Also, the parking

brake may not securely hold the vehi-

cle.

●

If the electronically controlled brake

system does not operate, do not follow

other vehicles closely and avoid hills or

sharp turns that require braking.

In this case, braking is still possible, but

the brake pedal should be depressed

more firmly than usual. Also, the brak-

ing distance will increase. Have your

brakes fixed immediately.

●

The brake system consists of 2 or more

individual hydraulic systems; if one of

the systems fails, the other(s) will still

operate. In this case, the brake pedal

should be depressed more firmly than

usual and the braking distance will

increase. Have your brakes fixed

immediately.

■

If the vehicle becomes stuck

Do not spin the wheels excessively when

a driven wheel is up in the air, or the vehi-

cle is stuck in sand, mud, etc. This may

damage the driveline components or

propel the vehicle forward or backward,

causing an accident.

NOTICE

■

When driving the vehicle

●

Do not depress the accelerator and

brake pedals at the same time during

driving, as this may restrain the hybrid

system output.

●

Do not use the accelerator pedal or

depress the accelerator and brake

pedals at the same time to hold the

vehicle on a hill.

• When vehicles ahead are hidden from

sight due to repeated curves, road divid-

ers or roadside trees

• When vehicles ahead appear from the

faraway lane on wide road

• When vehicles ahead have no lights

●

The high beams may be changed to the

shaded high beams if a vehicle ahead that

is using fog lights without its headlights

turned on is detected.

●

House lights, street lights, traffic signals,

and illuminated billboards or signs and

other reflective objects may cause the

high beams to change to the shaded high

beams, cause the high beams not to

change to the shaded high beams, or

change the area that is not illuminated.

●

The following factors may affect the

amount of time taken to turn the high

beam on or off, or the speed by which the

areas not illuminated change:

• The brightness of headlights, fog lights,

and tail lights of vehicles ahead

• The movement and direction of vehicles

ahead

• When a vehicle ahead only has opera-

tional lights on one side

• When a vehicle ahead is a two-wheeled

vehicle

• The condition of the road (gradient,

curve, condition of the road surface etc.)

• The number of passengers and amount of

luggage

●

The light distribution control of the head-

lights may change unexpectedly.

●

Bicycles or similar objects may not be

detected.

●

In the following situations the system may

not be able to correctly detect the sur-

rounding brightness level. This may cause

the low beams to remain on or the high

beams to flash or dazzle pedestrians or

ahead of the vehicle, such as a sign or

mirror

• When the back of a preceding vehicle is

highly reflective, such as a container on a

truck

• When the vehicle’s headlights are dam-

aged or dirty, or are not aimed properly

• When the vehicle is listing or tilting due to

a flat tire, a trailer being towed, etc.

• When the headlights are changed

between the high beams and low beams

repeatedly in an abnormal manner

• When the driver believes that the high

beams may be flashing or dazzling
