1996 TOYOTA SUPRA warning light

105
Leave the system on during ordinary
driving so that it can operate when
needed. When traction control is ap-
plied, the slip indicator light blinks. If
your vehicle still skids even though
traction control is applied, more pow-
erful
traction control is applied and the
SNOWº indicator light comes on.
You may hear a slight clicking noise in the
engine compartment when the engine is
started. This means that the traction con-
trol system is in the self-check mode, and
does not indicate malfunction. When the
traction control system is operating, you
may feel vibration of your vehicle, causedby operation of the brakes. This indicates
the system is functioning properly.
When getting the vehicle out of mud or
new snow, etc. the traction control system
will operate to prevent the wheels from
spinning. Even though the accelerator
pedal is fully depressed, the engine speed
will be restrained to a certain level.
MANUAL SNOW OPERATION
You can select the snow mode by
pushing the SNOWº switch. The
SNOWº indicator light will come on.
To select the automatic mode, push
the OFFº switch. The SNOWº indi-cator light will go off. If your vehicle
still skids, the system automatically operates.
MANUAL TRACTION CONTROL OFF
OPERATION
You can turn off the traction control
system by pushing the OFFº switch.
The TRAC OFFº indicator/warning
light will come on. Pushing the OFFº
switch a second time turns on the trac-
tion control system and the TRAC
OFFº indicator/warning light will go off. If the SNOWº indicator light is on,
pushing the OFFº switch once se-lects the automatic mode and pushing
it a second time turns off the traction
control system.

The amount of engine oil consumed
depends on
the viscosity of the oil, the
quality of the oil and the conditions
the vehicle is driven under.
More oil is consumed by high-speed driv-
ing and frequent acceleration and decel- eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.
When judging the amount of oil con-
sumption, note that the oil may be- come diluted and make it difficult to
judge the true level accurately.
As an example, if a vehicle is used for re-
peated short trips, and consumes a nor- mal amount of oil, the dipstick may not
show any drop in the oil level at all, even
after 1000 km (600 miles) or more. This is
because the oil is gradually becoming di-
luted with fuel or moisture, making it ap-
pear that the oil level has not changed.
The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making it appear that oil is excessively consumed
after driving at 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 be checked every time you refuel the vehicle.
NOTICE
Failure to check the oil level regularly could lead to serious
engine trouble due to insufficientoil.
For detailed information on oil level check,
see Checking the engine oil levelº in Chapter 7-2. 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.
Do not drive your vehicle with only
a single brake system. Have your
brakes fixed immediately.
CAUTION!
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 reservevacuum for one or two stopsÐbut no more!
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum re- serve.
CAUTION!
Brake system

Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hardÐmuch harder t han nor-
mal. And your braking distance will
be longer.
ANTI-LOCK BRAKE SYSTEM
The anti-lock brake system is designed to prevent lock-up of the wheels during sud-
den braking or braking on slippery road surfaces. This assists the driver in con-
trolling the vehicle under these circum-stances.
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.
When the anti-lock brake system function is in action, you may feel the brake pedal
pulsating and hear a noise. In this situa-
tion, to let the anti-lock brake system work for you, just hold the brake pedal
down more firmly. Do not pump the brake. 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 lossof 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 differences in surface height.
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.

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 re- placed by ones with the same load ca-
pacity, diameter, rim width, and offset. This must be observed on compact spare
tires, too.
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 chainclearance 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.
After driving your vehicle the first 1600
km (1000 miles), check that the wheel
nuts are tight.
If you have repaired or changed your
tires, check that the wheel nuts are still
tight after driving 1600 km (1000miles).
When using tire chains, be careful not
to damage the aluminum wheels.
Use only the Toyota wheel nuts and
wrench designed for your aluminumwheels.
When balancing your wheels, use only
Toyota balance weights or equivalent
and a plastic or rubber hammer.
As with any wheel, periodically checkyour aluminum wheels for damage. If
damaged, replace immediately.
