CAUTION
When jacking, be sure to observe the following to
reduce the possibility of personal injury:

Follow jacking instructions.

Do not put any part of your body under the vehicle
supported by a jack. Personal injury may occur.

Do not start or run the engine while your vehicle is
supported by the jack.

Stop the vehicle on a level firm ground, firmly set the
parking brake and put the transmission in ºPº
(automatic) or reverse (manual). Block the wheel
diagonally opposite to the one being changed if
necessary.

Make sure to set the jack properly in the jack point.
Raising the vehicle with jack improperly positioned
will damage the vehicle or may allow the vehicle to fall
off the jack and cause personal injury.

Never get under the vehicle when the vehicle is
supported by the jack alone; use vehicle support
stands.

Do not raise the vehicle with someone in the vehicle.

When raising the vehicle, do not put an object on or
under the jack.

FUEL PUMP SHUT OFF SYSTEM
The fuel pump shut off system stops supplying fuel to the
engine to minimize the risk of fuel leakage when the engine
stalls or an airbag inflates upon collision. To restart the engine
after the fuel pump shut off system activates, turn the ignition
switch to ºACCº or ºLOCKº once and start it.
CAUTION
Inspect the ground under the vehicle before restarting
the engine. If you find that liquid has leaked onto the
ground, it is the fuel system has been damaged and it is
in need of repair. In this case, do not restart the engine.
FACTS ABOUT ENGINE OILCONSUMPTION
Functions of engine oil
Engine oil has the primary function of lubricating and cooling
the inside of the engine, and plays a major role in maintaining
the engine in proper working order.
Engine oil consumption
It is normal that an engine should consume some engine
oil during normal engine operation. The causes of oil
consumption in a normal engine are as follows.
Oil is used to lubricate pistons, piston rings and cylinders.
A thin film of oil is left on the cylinder wall when a piston
moves downwards in the cylinder. High negative pressure
generated when the vehicle is decelerating sucks some of
this oil into the combustion chamber. This oil as well as
some part of the oil film left on the cylinder wall is burned by
the high temperature combustion gases during the
combustion process.
 Oil is also used to lubricate the stems of the intake valves.
Some of this oil is sucked into the combustion chamber
together with the intake air and is burned along with the fuel.
High temperature exhaust gases also burn the oil used to
lubricate the exhaust valve stems.

4. Pull the dipstick out and look at the oil level on the end. If
it is between the low level mark ( 4 ) and the full level mark
( 5 ), it is O.K.
SV62003
If the oil level is below or only slightly above the low level
mark, add engine oil of the same type as already in the
engine.
Remove the oil filler cap and add engine oil a little at a time,
checking the dipstick. The approximate quantity of oil needed
to fill between the low level mark and the full level mark on the
dipstick is indicated below for reference.
When the level reaches within the correct range, return the
filler cap and turn the cap clockwise until you hear a click.
Oil quantity. L (qt., lmp. qt.) 1.8 (1.9, 1.6)
NOTICE
Avoid overfilling, or the engine could be damaged. Check the oil level on the dipstick once again afteradding the oil.

*Change automatic transmission fluid only as necessary.
Generally, it is necessary to change automatic transmission
fluid only if your vehicle is driven under one of the Special
Operating Conditions listed in your ºOwner's Manual
Supplement/Scheduled Maintenanceº. When changing the
automatic transmission fluid, use only Toyota Genuine ATF
Type T±IV ( ATF JWS3309 or NWS6500) to aid in assuring
optimum transmission performance.NOTICE
Using automatic transmission fluid other than Toyota Genuine ATF T ype T±IV may cause deterioration in shift
quality, locking up of your transmission accompanied by vibration, and ultimately damage the automatictransmission of your vehicle.

CHECKING POWER STEERINGFLUID
SV63002
Check the fluid level on the dipstick. If necessary, add
automatic transmission fluid DEXRONII or III.
If the vehicle has been driven around 80 km/h (50 mph) for 20
minutes (a little more in frigid temperatures), the fluid is hot
(60 C ± 80C or 140F ± 175F). You may also check the level
when the fluid is cold (about room temperature, 10 C ± 30C
or 50F ± 85F) if the engine has not been run for about five
hours.

1. Clean all dirt off the reservoir.
2. Remove the reservoir cap by turning it counterclockwise
and wipe the dipstick clean.
3. Reinstall the reservoir cap.
4. Remove the reservoir cap again and look at the fluid level.
If the fluid is cold, the level should be in the ºCOLDº range on
the dipstick. Similarly, if it is hot, the fluid level should be in the
ºHOTº range. If the level is at the low side of either range, add
automatic transmission fluid DEXRON
II or III to bring the
level within the range.
5. After replacing the reservoir cap, visually check the
steering box case, vane pump and hose connections for leaks
or damage.

Chain installation
Install the chains on the rear tires as tightly as possible.
Do not use tire chains on the front 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.
CAUTION
Do not exceed 50 km/h (30 mph) or the chain
manufacturer's recommended speed limit,
whichever is lower.
 Drive carefully avoiding bumps, holes, and sharp
turns, which may cause the vehicle to bounce.
 Avoid sharp turns or locked±wheel braking, as use of
chains may adversely affect vehicle handling.
 When driving with chains installed, be sure to drive
carefully. slow down before entering the curves to
avoid losing control of the vehicle, it may cause an
accident.
NOTICE
Do not attempt to use a tire chain on the compact spare
tire, as it may result in damage to the vehicle as well asthe tire.
REPLACING WHEELS
When to replace your wheels
If you have wheel damage such as bends, cracks or heavy
corrosion, the wheel should be replaced.
If you fail to replace damaged wheels, the tire may slip off the
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.
