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 motor.
●When driving over bumps in the road,
drive as slowly as possible to avoid
damaging the wheels, underside of the
vehicle, etc.
●Make sure to idle the engine immedi-
ately after high-load driving. Stop the
engine only after the turbocharger has
cooled down.
Failure to do so may cause damage to
the turbocharger.
■If you get a flat tire while driving
A flat or damaged ti re may cause the fol-
lowing situations. Hold the steering
wheel firmly and gradually depress the
brake pedal to slow down the vehicle.
●It may be difficult to control your vehi-
cle.
●The vehicle will make abnormal
sounds or vibrations.
●The vehicle will lean abnormally.

■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 vehi-
cle:
●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 fol-
lowing:
●Brake function
●Changes in quantity and quality of oil
and fluid used for the engine, transmis-
sion, transfer (AWD models), differen-
tial, etc.
●Lubricant condition for the propeller
shaft, bearings and suspension joints
(where possible), and the function of
all joints, bearings, etc.
If the shift control system is damaged by
flooding, it may not be possible to shift
the shift position to P, or from P to other
positions. In this case, contact your Lexus
dealer.
■When parking the vehicle
Always set the parking brake, and shift
the shift position to P. Failure to do so
may cause the vehicle to move or the
vehicle may accelerate suddenly if the
accelerator pedal is accidentally
depressed.

 Have the vehicle fitted with four
snow tires or purchase a set of tire
chains for the rear tires.
*
Ensure that all tires are the specified size
and brand, and that chains match the size
of the tires.
*: Tire chains cannot be mounted on vehi-
cles with front and rear tires of differing
sizes.

Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or seri-
ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air
pressure.
●Do not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used.
●Use snow tires on all, not just some
wheels.
■When installing tire chains
Before installing tire chains, make sure to
disable all functions of the vehicle height
control of the electronically modulated
air suspension. Otherwise, the vehicle
height may change while installing the
tire chains and part or your body may be
caught under the vehicle, possibly caus-
ing injury. ( P.297)
■Driving with tire chains
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehicle
being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed
limit specified for the tire chains being
used, or 30 mph (50 km/h), which-
ever is lower.
●Avoid driving on bumpy road surfaces
or over potholes.
●Avoid sudden acceleration, abrupt
steering, sudden br aking and shifting
operations that cause sudden engine
braking.
●Slow down sufficiently before entering
a curve to ensure that vehicle control is
maintained.
●Do not use LTA (Lane Tracing Assist)
system.

Maintenance and care
●Do not use detergent on the brake cali-
pers when they are hot.
●Wash detergent off immediately after
use.
■Bumpers and side moldings
Do not scrub with abrasive cleaners.
■Front side windows water-repellent
coating (if equipped)
●The following precautions can extend the
effectiveness of the water-repellent coat-
ing.
• Remove any dirt, etc. from the front side windows regularly.
• Do not allow dirt and dust to accumulate
on the windows for a long period.
Clean the windows with a soft, damp
cloth as soon as possible.
• Do not use wax or glass cleaners that contain abrasives when cleaning the win-
dows.
• Do not use any metallic objects to remove condensation build up.
●When the water-repellent performance
has become insufficie nt, the coating can
be repaired. Contact your Lexus dealer.
■Plated portions
If dirt cannot be removed, clean the parts as
follows:
●Use a soft cloth dampened with an
approximately 5% solution of neutral
detergent and water to clean the dirt off.
●Wipe the surface with a dry, soft cloth to
remove any remaining moisture.
●To remove oily deposits, use alcohol wet
wipes or a similar product.
WARNING
■When washing the vehicle
Do not apply water to the inside of the
engine compartment. Doing so may
cause the electrical components, etc. to
catch fire.
■When cleaning the windshield
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wip-
ers may operate unexpectedly in the fol-
lowing situations, and may result in hands
being caught or other serious injuries
and cause damage to the wiper blades.
Off
AUTO
●When the upper part of the windshield
where the raindrop sensor is located is
touched by hand
●When a wet rag or similar is held close
to the raindrop sensor
●If something bumps against the wind-
shield
●If you directly touch the raindrop sen-
sor body or if something bumps into
the raindrop sensor
■Precautions regarding the exhaust
pipes and rear bumper diffusers
Exhaust gases cause the exhaust pipes
and rear bumper diffusers to become
quite hot.
When washing the vehicle, be careful not
to touch the pipes and diffusers until they
have cooled sufficiently, as touching hot
exhaust pipes and rear bumper diffusers
can cause burns.
■Precaution regarding the front
bumper (vehicles with Lexus Safety
System + A)
If the paint of the front bumper is chipped
or scratched, the Le xus Safety System +
A may not function correctly. If this
occurs, consult your Lexus dealer.
