The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making itappear that oil is excessively consumed
after driving as high speeds.
IMPORTANCE OF ENGINE OIL LEVEL CHECK
One of the most important points in proper vehicle maintenance is to keep the engine
oil at the optimum level so that oil function
will
not be impaired. Therefore, it is essen-
tial that the oil level be checked regularly.
Toyota recommends that the oil level bechecked every time you refuel the vehicle.
Failure to check the oil level
regularly could lead to serious
engine trouble due to insufficient oil.
NOTICE
For detailed information on the oil level
check, see Checking the engine oil levelº
in Chapter 7-2.
Your engine is fitted with twin ground elec- trode spark plugs.
Use only twin ground electrode
spark plugs for your engine
performance.
NOTICE
TANDEM MASTER CYLINDER BRAKE SYSTEM
The tandem master cylinder brake sys-
tem is a hydraulic system with two sepa-
rate sub-systems. If either sub-system
should fail, the other w ill still work. Howev-
er, the pedal will be harder to press, and
your stopping distance will be longer.
Also, the brake system warning light may come on.
CAUTION!
Do not drive your vehicle with only a single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power-assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserve
vacuum for one or two stops - but no more!

CAUTION!
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum re- serve.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard-much harder than nor-
mal. And your braking distance will
be longer.
ANTI-LOCK BRAKE SYSTEM (with ABSº warning light)
The anti-lock brake system is designed to automatically prevent lock-up of the
wheels during sudden braking or braking on slippery road surfaces. This assists in
providing directional stability and steeringperformance of the vehicle under these circumstances.
The anti-lock brake system becomes op- erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph). You may hear a sound in the engine
compartment for a
few seconds when the
engine is started or just after the vehicle is started. This means that the anti-lock
brake system is in the self check mode,
and does not indicate a malfunction.
Effective way to press the ABSº brake
pedal: When the anti-lock brake system
function is in action, you may feel the brake pedal pulsating and hear a noise.
In this situation, to let the anti-lock brake
system work for you, just hold the brake
pedal down more firmly. Do not pumpthe brake. This will result in reduced
braking performance.
The brake pedal pulsation caused by the
anti-lock brake system may indicate haz- ardous road surface conditions. Althoughthe anti-lock brake system assists in pro-
viding vehicle control, it is still important to
drive with all due care, because the anti-
lock brake system cannot overcome the
laws of physics that act on your vehicle: Braking c apability is dependent on tire
friction with the road surface.
Even though the anti-lock brake sys-
tem is operating, a driver cannot main- tain full control on certain slippery road
surfaces, when cornering at highspeeds, or in violent maneuvers.
Avoid high speeds on wet roads. The
anti-lock brake system cannot elimi-
nate the risk of hydroplaning and loss of tire friction.
Always maintain a safe distance from the
vehicle in front of you. Compared with ve-
hicles not fitted with an anti-lock brake
system, your vehicle may require a longer
stopping distance in the following cases: Driving on rough, gravel or snow-cov-
ered roads.
Driving with tire chains installed.
Driving on roads where the road sur-
face is pitted or has other differencesin surface height.
CAUTION!
Do not use tires other than the
manufacturer 's designated tires, and
do not mix tires or wheels of different
sizes. You may prevent the antilock brake system from operating at full effectiveness.

ABSº warning light
This light comes on when the ignition key is turned to the ONº position. After about
3 seconds, the light will go off.
If either of the following conditions occurs, this indicates a malfunction somewhere inthe parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle. The light does not come on as de-
scribed above, or remains on.
The light comes on while driving. Even if the anti-lock brake system
should
fail, the brake system will still operate con-
ventionally. However, when the `ABS''
warning light is on (and the brake system
warning light is off), the anti-lock brake
system is not assisting brake perfor-mance so that the wheels can lock-up
during sudden braking or braking on slip-
pery road surfaces. Have your vehicle
checked by your Toyota dealer as soon as
possible.The brake pad wear limit indicators on your disc brakes give a warning noise
when the brake pads are worn to
where replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary.

Tire surface and wheel nuts Check the tires carefully
for cuts, damage
or excessive wear. See Chapter 7-2 for
additional information. When checking the tires, make sure no nuts are missing,
and check the nuts for looseness. T ighten
them if necessary.
Tire rotation
Rotate the tires every 12000 km (7500
miles). See Chapter 7-2 for additional in- formation.
Fluid leaks Check underneath for leaking fuel, oil, wa-
ter or other fluid after the vehicle has been
parked for a while. If you smell fuel fumes
or notice any leak, have the cause found
and corrected immediately. Doors and engine hood Check that all doors including tailgate op- erate smoothly and all latches lock se-
curely. M ake sure the engine hood secon-
dary latch secures the hood from opening
when the primary latch is released. INSIDE THE VEHICLE Items listed below should be checked
regularly, e.g. while performing peri-
odic services, cleaning the vehicle,etc. LightsMake sure the headlights, stop lights, tail lights, turn signal lights, and other lights are all working. Check headlight aim. Service reminder indicators and
warn-
ing buzzersCheck that all service reminder indicators
and warning buzzers function properly. Steering wheel
Be alert for changes in steering condition, such as hard steering or strange noise. Seats Check that all seat controls such as seat
adjusters, seatback recliner, etc. operate
smoothly and that all latches lock securely
in any position. Check that the head re-
straints move up and down smoothly and
that the locks hold securely in any latched
position. For folding-down seatback
(bench seat), check that the latches lock
securely. Seat belts
Check that the seat belt system such as
buckles, retractors and anchors operate
properly and smoothly. Make sure that the
belt webbing is not cut, frayed, worn ordamaged.
Accelerator pedal Check the pedal for smooth operation and
uneven pedal effort or catching. Clutch pedal Check the pedal for smooth operation. Brake pedal Check
the pedal for smooth operation and
that the pedal has the proper clearance. Check the brake booster function. Brakes
At a safe place, check that the brakes do not pull to one side when applied. Parking brake Check that the lever has the proper travel and that, on a safe incline, your vehicle is
held securely with only the parking brake applied.
Automatic transmission Parkº mech-
anism
On a safe incline, check that your vehicle is held securely with the selector lever in Pº position and all brakes released.
IN THE ENGINE COMPARTMENT Items listed below should be checked
from time to time, e.g. each time when refueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See Chapter 7-3 for additional infor-
mation.

CAUTION
Do not drive with the snow tires in- correctly inflated.
Never drive over 120 km/h (75 mph)
with any type of snow tires.!
TIRE CHAIN SELECTION Use the tire chains of correct size.
Regulations regarding the use of tire
chains vary according to location or
type of r oad, so always check them be-
fore installing chains.
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, care- fully follow the instructions of the chain
manufacturer.
If wheel covers are used, they will be
scratched by the chain band, so removethe covers before putting on the chains.
Do not exceed 50 km/h (30 mph) or
the chain manufacturer's recom-
mended 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 ad- versely affect vehicle handling.
CAUTION! 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, the
tire may slip off the wheel or they may cause loss of handling control. WHEEL SELECTION
When replacing wheels, care should
be taken to ensure that the wheels are
replaced by ones with the same load
capacity, diameter, rim width, and off- set.
Correct
replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may ad-
versely affect handling, wheel and bear-
ing 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.
Replacement with used wheels is not rec-
ommended as they may have been sub- jected to rough treatment or high mileageand could fail without warning. Also, bent
wheels which have been straightened
may have structural damage and there-
fore should not be used. Never use an in-
ner tube in a leaking wheel which is de-
signed for a tubeless tire.

204Traction A, B, C
ÐThe traction grades,
from highest to lowest, are A, B, and C,
and they represent the tire's ability to stop
on wet pavement as measured under
controlled conditions on specified govern-
ment test surfaces of asphalt and con-
crete. A tire marked C may have poor trac-
tion performance.
Warning: The traction grade assigned to this tire is based on braking (straight
ahead) traction tests and does not include
cornering (turning) traction.
Temperature A, B, C ÐThe temperature
grades are A (the highest), B, and C, rep-
resenting the tire's resistance to the gen-
eration of heat and its ability to dissipate heat when tested under controlled condi- tions on a specific indoor laboratory test
wheel. Sustained high temperature can cause the material of the tire life, and ex- cessive temperature can lead to sudden
tire failure. The grade C corresponds to a level of performance which all passenger
car tires must meet under the Federal Mo-
tor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law. Warning: The temperature grades for this tire
are established for a tire that is proper-
ly inflated and not overloaded. Excessive speed, underinflation, or excessive load- ing, wither separately or in combination, can cause heat buildup and possible tirefailure. This information has been prepared in
