CAUTION
Do not rely excessively on the vehicle skid control
system. Even if the vehicle skid control system is
operating, it is not that your vehicle is absolutely
safe. Reckless driving will result in an unexpected
accident. Always keep safety driving in mind. If the
slip indicator light flashes, sounding an alarm,
special care should be taken while driving.
Only use tires of specified size. The size,
manufacturer, brand and tread pattern for all 4 tires
should be the same. If you use the tires other than
specified, or different type or size, the vehicle skid
control system may not function correctly. When
replacing the tires or wheels, contact your Lexus
dealer.

BRAKE PAD WEAR LIMITINDICATORS
31E016
The brake pad wear limit indicators on your disc
brakes give a warning noise when the brake pads
are worn to the extent that replacement is required.
If you hear a squealing or scraping noise while driving,
have the brake pads checked and replaced by your
Lexus dealer as soon as possible. Expensive rotor
damage can result if the pads are not replaced when
needed.TYPES OF TIRES
Determine what kind of tires your vehicle is originally
equipped with.
1. Summer tires
Summer tires are high±speed capability tires best suited
to highway driving under dry conditions.
Since summer tires do not have the same traction
performance as snow tires, summer tires are
inadequate for driving on snow±covered or icy roads.
For driving on snow±covered or icy roads, we
recommend using snow tires. If installing snow tires, be
sure to replace all four tires.

DRIVING TIPS
333
Tires
Ensure that your vehicle's tires are properly inflated.
Adjust the tire pressure to the recommended cold tire
pressure indicated below:
Tire pressure, kPa (kgf/cm
2 or bar, psi)
Front 220 (2.2, 32)
Rear 220 (2.2, 32)
The trailer tires should be inflated to the pressure
recommended by the trailer manufacturer in respect
to the total trailer weight.
Trailer lights
Trailer lights must comply with federal,
state/provincial and local regulations. See your local
recreational vehicle dealer or rental agency for the
correct type of wiring and relays for your trailer.
Check for correct operation of the turn signals and
stop lights each time you hitch up. Direct splicing may
damage your vehicle's electrical system and cause a
malfunction of your lights.
Break±in schedule
Lexus recommends that you do not tow a trailer with
a new vehicle or a vehicle with any new power train
component (engine, transmission, differential, wheel
bearing, etc.) for the first 800 km (500 miles) of
driving.
Maintenance
If you tow a trailer, your vehicle will require more
frequent maintenance due to the additional load. For
this information, please refer to the scheduled
maintenance information in the ªOwner's Manual
Supplement/ Maintenance Scheduleº.
Retighten all fixing bolts of the towing ball and bracket
after approximately 1000 km (600 miles) of trailer
driving.
Pre±towing safety check
Check that your vehicle remains level when a loaded
or unloaded trailer is hitched. Do not drive if the
vehicle has an abnormal nose±up or nose±down
condition, and check for improper tongue load,
overload, worn suspension or other possible causes.
Make sure the trailer cargo is securely loaded so that
it cannot shift.
Check that your rear view mirrors conform to any
federal, state/provincial or local regulations. If they
do not, install required rear view mirrors appropriate
for towing purposes.

Tire selection
When replacing a tire, use only the same size and
construction as originally installed and with the
same or greater load capacity.
Using any other size or type of tire may seriously affect
handling, ride, speedometer/odometer calibration,
ground clearance, and clearance between the body and
tires or snow chains.
Do not mix radial, belted, or conventional tires on
your vehicle.
Do not use tires or wheels other than the
manufacturer's recommended size.
It can cause dangerous handling characteristics,
resulting in loss of control. If you need to change from
conventional tires to radial tires or vice versa, replace
them as a set.
INSTALLING SNOW TIRES AND CHAINS
When to use snow tires or chains
Snow tires or chains are recommended when
driving on snow or ice.
On wet or dry roads, conventional or radial tires provide
better traction than snow or studded tires.
Snow tire selection
If you need snow tires, select the same size,
construction and load capacity as the original tires
on your Lexus.
Do not use tires other than stated above. Since your
vehicle has radial tires as original equipment, make sure
your snow tires also have radial construction. Do not
install studded tires without first checking local
regulations for possible restrictions.
Snow tire installation
Snow tires should be installed on all wheels.
Installing snow tires on the front wheels only can lead to
an excessive difference in road grip capability between
the front and rear tires which could cause loss of vehicle
control.

CHASSIS
438
CAUTION
Snow tires should be inflated to the same pressure as
the original tires.
Never drive over 120 km/h (75 mph) with any type of
snow tires.
Tire chain selection
Regulations regarding the use of tire chains vary
according to location or type of road. Always check
the local regulations before installing chains.
Use SAE Class ªSº type radial tire chains, with the
exception of radial cable chains or V±bar type chains.
Chain installation
Install the chains on the front tires as tightly as
possible. Do not use tire chains on the rear tires.
Retighten chains after driving 0.5 ± 1.0 km (1/4 ± 1/2
mile).
When installing chains on your tires, carefully follow the
instructions of the chain manufacturer.

REPLACING WHEELS
When to replace your wheels
If you have wheel damage such as bending, cracks
or heavy corrosion, the wheel should be replaced.
If you fail to replace damaged wheels, a tire may slip off
a wheel or cause loss of handling control.
Replacement with used wheels is not recommended as
they may have been subjected to rough treatment or
high mileage and could fail without warning. Also, bent
wheels which have been straightened may have hidden
structural damage and therefore should not be used.
Never use an inner tube in a leaking wheel which is
designed for a tubeless tire.
Wheel selection
When replacing wheels, care should be taken to
ensure that they are equivalent to those removed in
load capacity, diameter, rim width, and offset.
Correct replacement wheels are available at your Lexus
dealer.
A wheel of a different size or type may adversely affect
handling, wheel and bearing life, brake cooling,
speedometer/odometer calibration, stopping ability,
headlight aim, bumper height, vehicle ground clearance,
and tire or snow chain clearance to the body and
chassis.
ALUMINUM WHEEL PRECAUTIONS
When installing aluminum wheels, check that the
wheel nuts are tight after driving your vehicle the first
1600 km (1000 miles).
If you have rotated, repaired, or changed your tires,
check that the wheel nuts are still tight after driving
1600 km (1000 miles).
When using tire chains, be careful not to damage the
aluminum wheels.
Use only the Lexus wheel nuts and wrench designed
for your aluminum wheels.
When balancing your wheels, use only Lexus
balance weights or equivalent and a plastic or rubber
hammer.
As with any wheel, periodically check your aluminum
wheels for damage. If damaged, replace
immediately.
