CHASSIS
364The recommended cold tire pressures, tire size and the
vehicle capacity weight are given on the label.
You should check the tire pressures every two weeks, or at
least
once a month. And don't forget the spare! The pressure
for the spare tire should be same with that for the standard tire.
(See page 356 or 358.) Incorrect tire pressure can reduce tire
life and make your vehicle less safe to drive.
Low tire pressure results in excessive wear, poor handling,
reduced fuel economy, and the possibility of blowouts from
overheated tires. Also, low tire pressure can cause poor
sealing of the tire bead. If the tire pressure is excessively low,
there is the possibility of wheel deformation and/or tire
separation. So keep your tire pressures at the proper level. If
a tire needs frequent refilling, have it checked by your Lexus
dealer. High tire pressure produces a harsh ride, handling problems,
excessive wear at the center of the tire tread, and a greater
possibility of tire damage from road hazards.
The following instructions for checking tire pressure should
be observed:

The pressure should be checked only when the tires are
cold. If your vehicle has been parked for at least 3 hours
and has not been driven for more than 1.5 km or 1 mile
since, you will get an accurate cold tire pressure reading.
 Always use a tire pr essure gauge. The appearance of the
tire can be misleading. Besides, tire pressures that are even
just a few pounds off can degrade handling and ride.
 Do not bleed or reduce tire pressure after driving. It is
normal for the tire pressure to be higher after driving.
 Never exceed the vehicle capacity weight. The
passengers and luggage weight should be located so that
the vehicle is balanced.
 Be sure to reinstall the tire valve caps. Without the valve
caps, dirt or moisture could get into the valve core and
cause air leakage. If the caps have been lost, have new
ones put on as soon as possible.

CHECKING BATTERYCONDITION
Precautions
CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and explosive hydrogen gas.

Do not cause a spark by contacting the battery terminals
with tools.

Do not smoke or light a match near the battery.
The electrolyte contains poisonous and corrosive sulfuric acid.

Avoid contact with eyes, skin or clothes.

Never inhale or swallow electrolyte.

Wear protective safety glasses when working near the
battery.

Keep children away from the battery.
EMERGENCY MEASURES

If electrolyte gets in your eyes, flush your eyes with clean
water for at least 15 minutes and get immediate medical
attention. If possible, continue to apply water with a sponge
or cloth while traveling to the medical office.

Before checking the headlight aim:
1. Be sure that the body around the headlight is not deformed.
2. Park the vehicle on a level spot.
3. The driver should stay in the driver's seat so that the
vehicle has its normal load (with the tank full).
4. Bounce the vehicle several times.

Check the interior of your vehicle.
Water and dirt can
accumulate under the floor mats and could cause corrosion.
Occasionally check under the mats to make sure the area is
dry. Be particularly careful when transporting chemicals,
cleansers, fertilizers, salt, etc. These should be transported in
proper containers. If a spill or leak should occur, immediately
clean and dry the area.
Use mud shields on your wheels. If you drive on salted or
gravel roads, mud shields help protect your vehicle. Full size
shields, which come near to the ground as possible, are the
best. We recommend that the fittings and the area where the
shields are installed be treated to resist corrosion. Your Lexus
dealer will be happy to assist in supplying and installing the
shields if they are recommended for your area.
Keep your vehicle in a well ventilated garage or a roofed
place. Do not park your vehicle in a damp, poorly
ventilated garage. If you wash your vehicle in the garage,
or if you drive it in covered with water or snow, your garage
may be so damp it will cause corrosion. Even if your garage
is heated, a wet vehicle can corrode if the ventilation is poor.
WASHING AND WAXING
Washing your Lexus
Keep your vehicle clean by regular washing.
The following cases may cause weakness to the paint or
corrosion to the body and parts. Wash your vehicle as soon
as possible.

When driving in a coastal area

When driving on a road sprinkled with antifreeze

When having stuck of coal tar, tree sap, bird droppings and
carcass of an insect

When driving in the areas where there is a lot of smoke,
soot, dust, iron dust and chemical substance

When the vehicle becomes remarkably dirty with dust and
mud
Hand±washing your Lexus
Work in the shade and wait until the vehicle body is not hot
to the touch.
1. Rinse off loose dirt with a hose. Remove any mud or road
salt from the underside of the vehicle or in the wheel wells.
2. Wash with a mild car±wash soap, mixed according to the
manufacturer 's instructions. Use a soft cotton mitt and keep
it wet by dipping it frequently into the wash water. Do not rub
hard ± let the soap and water remove the dirt.
