(d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.
NOTICE
Do not continue driving if the engine
drive belt is broken or loose.
(e) Malfunction Indicator Lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty.
(See “Fuel gauge” in this section for
instructions.)
b. The fuel tank cap is not tightened se-
curely. (See “Fuel tank cap” in Section
1−2 for instructions.)
c. There is a problem somewhere in your
engine or automatic transmission elec-
trical system.If it comes on while you are driving in
case c, have your vehicle checked/re-
paired by your Toyota dealer as soon as
possible.
(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.
(g) Low Oil Pressure Warning Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.
(h) “ABS” Warning Light
The light comes on when the ignition key
is turned to the “ON” position. If the anti−
lock brake system and the brake assist
system works properly, the light turns off
after a few seconds. Thereafter, if the
system malfunctions, the light comes on
again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti−lock brake system, the brake assist
system, the traction control system and
vehicle skid control system do not oper-
ate, but the brake system still operates
conventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti−lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.

ing light, immediately stop your ve-
hicle at a safe place and contact your

mote control transmitter.

sliding door is opened or in the process
of closing with the power sliding door sys-
tem on, a buzzer will sound and the open
power sliding door warning light will flash.

tion key is turned to the “ACC” or
“ON” position. After about 6 seconds,

bag sensor assembly, front airbag sen-
sors, side airbag sensor, front seat belt
pretensioner assemblies, inflators, warning
light, interconnecting wiring and power
sources.

(o) Low Tire Pressure Warning Light
This light warns that the tire pressure of
any one of the tires is critically reduced.
The light comes on when the ignition key
is turned to the “ON” position. It goes off
after a few seconds. This indicates that
the low tire pressure warning system is
functioning properly.
If the light comes on while driving, adjust
tire pressure to the specified level. (See
“Tires” in Section 8.) After the tire pres-
sure is adjusted, the light should go off
after driving at about more than 30 km/h
(19 mph) for some time. If the light still
remains, have the low tire pressure warn-
ing system checked at your Toyota dealer.

AUTOMATIC TRACTION CONTROL
SYSTEM
The traction control system automatical-
ly helps control the spinning of the
front wheels which may occur when ac-
celerating on slippery road surfaces,
thus assisting driver to control the driv-
ing power of the front wheels.
When you turn the ignition switch on,
the traction control system always
turns on automatically, and the slip in-
dicator light and “TRAC OFF” indicator/
warning light will come on. The indica-
tor lights will go off after a few
seconds.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.
While the “TRAC OFF” indicator/warning
light and “VSC” warning light come on, the
traction control system cannot be oper-
ated.
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 traction
control system is in the self−check mode,
and does not indicate malfunction.
When the traction control system is oper-
ating, you may feel vibration or noise of
your vehicle, caused by operation of the
brakes. This indicates the system is func-
tioning properly.
When getting the vehicle out of mud or
new snow, etc. the traction control system
will help operate to prevent the wheels
from spinning.
