2-1. Driving procedures
CAUTION
nWhen driving on slippery road surfaces
lSudden braking, acceleration and steering may cause tire slippage and reduce
your ability to control the vehicle, resulting in an accident.
lSudden changes in engine speed, such as engine braking caused by up-shifting
and down-shifting, may cause the vehicle to skid, resulting in an accident.
lAfter driving through a puddle, lightly depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the brakes from
functioning properly. If the brakes on only one side are wet and not functioning
properly, steering control may be affected, resulting in an accident.
nWhen shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.
nWhen the vehicle is stopped
lDo not race the engine.
If the vehicle is in any gear other than P or N, the vehicle may accelerate suddenly
and unexpectedly, causing an accident.
lDo not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and
check that exhaust fumes do not enter the vehicle interior.
lIn order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while the engine is running, and apply the parking
brake as necessary.
lIf the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, always depress the brake pedal and securely
apply the parking brake as needed.
lAvoid 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.

2-1. Driving procedures
NOTICE
nTo prevent battery discharge
lDo not leave the “ENGINE START STOP” switch in ACCESSORY or IGNI-
TION ON mode for long periods of time without the engine running.
lIf the indicator on the “ENGINE START STOP” switch is illuminated, the
“ENGINE START STOP” switch is not off. When exiting the vehicle, always
check that the “ENGINE START STOP” switch is off.
lDo not stop the engine when the shift lever is in a position other than P. If the
engine is stopped in another shift lever position, the “ENGINE START STOP”
switch will not be turned off but instead be turned to ACCESSORY mode. If the
vehicle is left in ACCESSORY mode, battery discharge may occur.
nWhen starting the engine
lDo not race a cold engine.
lIf the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.
nSymptoms indicating a malfunction with the “ENGINE START STOP” switch
If the “ENGINE START STOP” seems to be operating somewhat differently than
usual, such as the switch sticking slightly, there may be a malfunction. Contact your
Lexus dealer immediately.

CAUTION
nIf a safety system warning light does not come on
Should a safety system light such as the ABS and SRS airbag warning light not
come on when you start the engine, this could mean that these systems are not
available to help protect you in an accident, which could result in death or serious
injury. Have the vehicle inspected by your Lexus dealer immediately if this occurs.

cle’s systems. (→P. 535)

2-3. Operating the lights and windshield wipers
nRaindrop sensor (vehicles with rain-sensing windshield wipers)
lIf the wiper switch is turned to the position while the “ENGINE START
STOP” switch is in IGNITION ON mode, the wipers will operate once to show
that “AUTO” mode is activated.
lWhen the sensor sensitivity ring is turned toward high while in “AUTO” mode,
the wipers will operate once to indicate that the sensor sensitivity is enhanced.
lIf the temperature of the raindrop sensor is 194°F (90°C) or higher, or 5°F
(-15°C) or lower, automatic operation may not occur. In this case, operate
the wipers in any mode other than “AUTO”.
nIf no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
CAUTION
nCaution regarding the use of windshield wipers in “AUTO” mode (vehicles with
rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or the
windshield is subject to vibration in “AUTO” mode. Take care that your fingers or
anything else do not become caught in the windshield wipers.
lThe raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.
