Regulations regarding the use of tire
chains vary depending on location and
type of road. Always check local regu-
lations before installing chains.
■Tire chain installation
Observe the following precautions when
installing and removing chains:
●Install and remove tire chains in a safe
location.
●Install tire chains on the front tires only.
Do not install tire chains on the rear tires.
●Install tire chains on fr ont tires as tightly as
possible. Retighten chains after driving
1/4 1/2 mile (0.5 1.0 km).
●Install tire chains following the instruc-
tions provided with the tire chains.
To enable the windshield wipers to be
lifted when heavy snow or icy condi-
tions are expected, change the rest
position of the windshield wipers from
the retracted position below the hood
to the service position using the wiper
lever. ( P.206) 
Specific design characteristics give
it a higher center of gravity than
ordinary passenger cars. This vehi-
cle design feature causes this type
of vehicle to be more likely to
rollover. And, utility vehicles have a
significantly higher rollover rate
than other types of vehicles.
 An advantage of th e higher ground
clearance is a better view of the
road allowing you to anticipate
problems.
 It is not designed for cornering at
the same speeds as ordinary pas-
senger cars any more than
low-slung sports cars are designed
to perform satisfactorily under
off-road conditions. Therefore,
sharp turns at excessive speeds may
cause the vehicle to rollover.

Maintenance and care
■Brake pads and calipers
Rust may form if the vehicle is parked with
wet brake pads or disc rotors, causing them
to stick. Before parking the vehicle after it is
washed, drive slowly and apply the brakes
several times to dry the parts.
■Bumpers
Do not scrub with abrasive cleaners.
■Front side windows water-repellent
coating
●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 insufficient, 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 switch is in “AUTO”, the wipers may
operate unexpectedly in the following sit-
uations, 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
pipe
Exhaust gasses cause the exhaust pipe to
become quite hot.
When washing the vehicle, be careful not
to touch the pipe until it has cooled suffi-
ciently, as touching a hot exhaust pipe
can cause burns.
■Precaution regarding the rear
bumper
If the paint of the re ar bumper is chipped
or scratched, the following systems may
not function correctly. If this occurs, con-
sult your Lexus dealer.
