DOITYOURSELF SERVICE
PRECAUTIONS
If you perform maintenance yourself, be sure to follow the
correct procedure given in this Section.
You should be aware that improper or incomplete servicing may
result in operating problems.
Performing doityourself maintenance during the warranty period
may affect your warranty coverage. Read the separate Lexus
Warranty statement for details and suggestions.
This Section gives instructions only for those items that are
relatively easy for an owner to perform. As explained in Section 5,
there are still a number of items that must be performed by a qualified
technician with special tools.
For information on tools and parts for doityourself maintenance,
see ”Parts and tools”.
Utmost care should be taken when working on your vehicle to
prevent accidental injury. Here are a few precautions that you should
be especially careful to observe:
CAUTION
When the engine is running, keep hands, clothing, and tools
away from the moving fan and engine drive belt.
(Removing rings, watches, and ties is advisable.)
Right after driving, the engine compartment the engine,
radiator, exhaust manifold and power steering fluid
reservoir, etc. will be hot. So be careful not to touch them.
Oil and other fluids may also be hot.
Do not smoke, cause sparks or allow open flames around
fuel or the battery. Their fumes are flammable.
Be extremely cautious when working on the battery. It
contains poisonous and corrosive sulfuric acid.
Do not get under your vehicle with just the body jack
supporting it. Always use automotive jack stands or other
solid supports.
Be sure the ignition is off if you work near the electric
cooling fan or radiator grille. With the ignition on, the
electric cooling fan may automatically start to run if the air
conditioning is on and/or if the coolant temperature is high.
Use eye protection whenever you work on or under your
vehicle where you may be exposed to flying or falling
material, fluid spray, etc.

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 rear 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.

Synthetic Leather Areas
(Dash and sun visors)
The synthetic leather areas may be easily cleaned with a mild
soap or detergent and water.
First vacuum over the upholstery to remove loose dirt. Then, using
a sponge or soft cloth, apply the soap solution to the synthetic leather.
After allowing it to soak in for a few minutes to loosen the dirt,
remove the dirt and wipe off the soap with a clean damp cloth. If all
the dirt does not come off, repeat the procedure. Commercial
foamingtype cleaners are also available which work well. Follow
the manufacturer’s instructions.
NOTICE
Do not use solvent, thinner, gasoline or window cleaner on the
interior.
Carpets, Windows and Seat Belts
Begin by vacuuming thoroughly to remove as much dirt as possible.
Several types of foam cleaners are available; some are in aerosol
cans and others are powders or liquids which you mix with water to
produce a foam. To shampoo the carpets, use a sponge or brush to
apply the foam. Rub in overlapping circles. Do not apply water
the best results are obtained by keeping the carpet as dry as possible.
Read the shampoo instructions and follow them closely.
The seat belts may be cleaned with mild soap and water or with
lukewarm water.
Use a cloth or sponge. As you are cleaning, check the belts for
excessive wear, fraying or cuts.
NOTICE
Use a good foamtype shampoo to clean the carpets.
Do not use dye or bleach on the belts it may weaken them.
The windows may be cleaned with any household window
cleaner.
When cleaning the inside of the rear window, be careful not
to scratch or damage the heater wires.
