CAUTION
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may result in serious injury:
• Do not touch the disc wheels or the area around the brakes immediately after
the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the
brakes will be extremely hot. Touching these areas with hands, feet or other
body parts while changing a tire, etc. may result in burns.
• Do not attach a heavily damaged wheel ornament, as it may fly off the wheel
while the vehicle is moving.
●Failure to follow these precautions could cause the wheel nuts to loosen and the
tire to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened, leading
to bolt or disc wheel damage. In addition, the oil or grease can cause the
wheel nuts to loosen and the wheel may fall off, causing a serious accident.
Remove any oil or grease from the wheel bolts or wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 103 N
•m (10.5 kgf•m,
76 f t
•lbf) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifically
designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or bolt
holes of the wheel, have the vehicle inspected by your Lexus dealer or
repairer, or another duly qualified and equipped professional immediately.
■Replacing a flat tire for vehicles with power back door
In cases such as when replacing tires, make sure to turn off the power back door
main switch (→P. 62). Failure to do so may cause the back door to operate uninten-
tionally if the power back door switch is accidentally touched, resulting in hands and
fingers being caught and injured.

If your vehicle has to be stopped in an emergency
CAUTION
■If the engine has to be turned off while driving
Power assist for the brakes and steering wheel will be lost, making the brake pedal
harder to depress and the steering wheel heavier to turn. Decelerate as much as
possible before turning off the engine.
Only in an emergency, such as if it becomes impossible to stop the vehicle
in the normal way, stop the vehicle using the following procedure:
Steadily step on the brake pedal with both feet and firmly
depress it.
Do not pump the brake pedal repeatedly as this will increase the
effort required to slow the vehicle.
Shift the shift lever to N.
If the shift lever is shifted to N
After slowing down, stop the vehicle in a safe place by the road.
Stop the engine.
If the shift lever cannot be shifted to N
Keep depressing the brake pedal with both feet to reduce vehi-
cle speed as much as possible.
To stop the engine, press and
hold the “ENGINE START
STOP” switch for 2 consecutive
seconds or more, or press it
briefly 3 times or more in suc-
cession.
Stop the vehicle in a safe place by the road.
