76GAUGES, METERS AND SERVICE REMINDER INDICATORS
While driving on steep inclines or rough
roads which causes the vehicle to sub-
stantially sway or on curves, this light
may come on due to the movement of
engine oil in the engine.
In normal conditions, due to engine oil
consumption, this light may come on earli-
er than the specified service interval of
the scheduled maintenance. This is be-
cause the engine oil is consumed to the
low level within the scheduled mainte-
nance interval and does not indicate a
problem. (For detailed information, see
“Facts about engine oil consumption” on
page 123 in Section 2.)
NOTICE
Continued engine operation with low
engine oil will damage the engine.
(e) Malfunction Indicator Lamp
This lamp comes on in the following
cases.
a. On some models: The fuel tank is
completely empty. (See “Fuel gauge”
on page 68 in this Section for instruc-
tions.)
b. There is a problem somewhere in the
engine electricalsystem, electronic en-
gine control system orengine emission
control system.
If it comes on while you are driving in
case b, have your vehicle checked/re-
paired by any authorized Toyota dealer or
repairer, or another duly qualified and
equipped professional, as soon as pos-
sible.If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic engine controlsystem. Stop the ve-
hicle and contact any authorized Toyota
dealer or repairer, or another duly quali-
fied and equipped professional, or take
your vehicle carefully, since the vehicle
performance will be lower than normal, to
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional, as soon as possible.
Even if the abnormality in the electronic
engine controlsystem is corrected during
low speed driving, thesystem may not
recover until the engine is stopped and
the engine switch is turned to the “ACC”
or “LOCK” position.
The lamp flashes when the engine emis-
sion control system is not functioning cor-
rectly. If the engine is run for more than
50 hours with the lamp flashing, the sys-
tem will automatically reduce engine per-
formance until the malfunction is cor-
rected.
(f) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.

124INFORMATION BEFORE DRIVING YOUR TOYOTA
The tandem master cylinder brakesystem
is a hydraulic system with two separate
sub−systems. If either sub−system should
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will increase. 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
bringthevehicletoastopwithnormal
pedal pressure. There is enough reserved
vacuum for one or two stops—but no
more!
CAUTION
DDo not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your reserved vacu-
um.
DEven 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
increase.
ANTI−LOCK BRAKE SYSTEM
(with “ABS” warning light)
The anti−lock brake system is designed
to help prevent lock−up of the wheels
during a sudden braking or braking on
slippery road surfaces. This assists in
providing directional stability and steer-
ing performance of the vehicle under
these circumstances.
Effective way to press the ABS brake
pedal:
When the anti−lock brake system func-
tion is in action, you may feel the brake
pedal pulsating and hear a noise. In this
situation, to let the anti−lock brake sys-
tem work for you, just hold the brake
pedal down more firmly. Do not pump
the brake in a panic stop. This will re-
sult in reduced braking performance.
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).
Depressing the brake pedal on slippery
road surfaces such as on a manhole cov-
er, a steel plate at a construction site,
joints in a bridge, etc. on a rainy day
tends to activate the anti−lock brake sys-
tem.
You may hear a click or motor sound from
the area around the front axle for a few
seconds when the engine is started or just
after the vehicle begins to move. This
means that the anti−lock brake system is
in the self−check mode, and does not indi-
cate a malfunction.

200DO−IT−YOURSELF MAINTENANCE: Engine and Chassis
If any of the above parts are extremely
dirty or you are not sure of their condi-
tion, take your vehicle to any authorized
Toyota dealer or repairer, or another duly
qualified and equipped professional.
CAUTION
To prevent burning yourself, be care-
ful not to touch the radiator, con-
denser and intercooler when the en-
gine is hot.
NOTICE
To prevent damage to the radiator,
condenser and intercooler, do not per-
formtheworkbyyourself.
When the fuel filter warning light
comes on, the water in the fuel filter
must be drained immediately.
Place a small tray under the drain plug to
catch the water.
1. Turn the drain plug about 2—2−1/2
turns, as shown above. (Loosening
more than this will cause water oozing
from around the drain plug.)
2. Operate the priming pump until fuel be-
gins to run out.
After draining, retighten the drain plug. Do
not use a tool.

DO−IT−YOURSELF MAINTENANCE: Engine and Chassis205
CAUTION
DDo not exceed 50 km/h (30 mph) or
the chain manufacturer ’s recom-
mended speed limit, whichever is
lower.
DDrive carefully avoiding bumps,
holes, and sharp turns, which may
cause the vehicle to bounce.
DAvoid sharp turns or locked−wheel
braking as use of chains may ad-
versely affect vehicle handling.
DWhen driving with chains installed,
be sure to drive carefully. Slow
down before entering curves to
avoid losing control of the vehicle.
Otherwise an accident may occur.
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 a damaged wheel,
the tire may slip off the wheel or 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 inset


(single wheels) or offset (dual wheels).
Correct replacement wheels are available
at any authorized Toyota dealer or repair-
er, or another duly qualified and equipped
professional.

: Conventionally referred to as “offset”.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stoppingability,headlight
aim, bumper height, vehicle ground clear-
ance, 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 mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.
