CAUTION
■When driving the vehicle
●Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Moving the shift lever to N while the vehicle is moving will disengage the engine
from the transmission. Engine braking is not available when N is selected.
●During normal driving, do not tune off the engine. Turning the engine off while
driving will not cause loss of steering or braking control, but the power assist to
these systems will be lost. This will make it more difficult to steer and brake, so you
should pull over and stop the vehicle as soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible to stop
the vehicle in the normal way: →P. 74 9
●Use engine braking (downshift) to maintain a safe speed when driving down a
steep hill.
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. ( →P. 1 8 7 )
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents, resulting
in death or serious injury.

NOTICE
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for an
extended period of time.
Doing so may damage the power steering pump.
●When driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( →P. 7 2 1 )
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to
have your Lexus dealer check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transmission,
transfer, differentials, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where
possible), and the function of all joints, bearings, etc.

■Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be suspended
if the engine is turned on and off repeatedly in a short period of time. In this case,
refrain from operating the engine. After about 10 seconds, the steering lock motor
will resume functioning.
■When the “ENGINE START STOP” switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by your Lexus
dealer immediately.
■If the electronic key battery is depleted
→ P. 6 4 4
CAUTION
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the acceler-
ator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■Caution while driving
If the vehicle begins to slide due to engine failure or other circumstances, do not
lock or open the doors until the vehicle reaches a safe and complete stop. Activa-
tion of the steering lock in this circumstance may lead to an accident, resulting in
death or serious injury.
■Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle, press and
hold the “ENGINE START STOP” switch for more than 3 seconds. However, do
not touch the “ENGINE START STOP” switch while driving except in an emer-
gency. Turning the engine off while driving will not cause loss of steering or braking
control, but the power assist to these systems will be lost. This will make it more diffi-
cult to steer and brake, so you should pull over and stop the vehicle as soon as it is
safe to do so.
