Installation of a mobile
two−way radio system
As the installation of a mobile two−way radio system in
your vehicle could affect electronic systems such as
multiport fuel injection system/sequential multiport fuel
injection system, cruise control system, anti−lock brake
system, traction control system, vehicle skid control sys-
tem, SRS airbag system and seat belt pretensioner sys-
tem, be sure to check with your Toyota dealer for pre-
cautionary measures or special instructions regarding
installation.
Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in
your Toyota contain explosive chemicals. If the vehicle
is scrapped with the airbags and pretensioners left as
they are, this may cause an accident such as fire. Be
sure to have the systems of the SRS airbag and seat
belt pretensioner removed and disposed of by the quali-
fied service shop or by your Toyota dealer before you
dispose of your vehicle.

(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.

(l) “VSC” Warning Light
The light warns that when there is a prob-
lem somewhere in the vehicle skid control
system or traction control system.
The light will come on when the ignition
key is turned to “ON”, and will go off after
about a few seconds. This means that the
system is operating properly.
If the “VSC” warning light comes on, the
vehicle skid control system and traction
control system do not work. However, as
conventional braking operates when ap-
plied, there is no problem to continue your
driving.
If any of the following conditions occur,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle:
The “VSC” warning light does not come
on after the ignition is turned to on.
The “VSC” warning light is left on after
the ignition is turned to on.
The “VSC” warning light comes on
while driving.(m) “TRAC OFF” Indicator/Warning Light
The light warns that when there is a prob-
lem somewhere in the vehicle skid control
system or traction control system.
The light will come on when the ignition
key is turned to “ON”, and will go off after
about a few seconds. This means that the
system is operating properly.
If the “TRAC OFF” indicator light comes
on, the traction control system does not
work. However, as conventional braking
operates when applied, there is no prob-
lem to continue your driving.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle:
The “TRAC OFF” indicator/warning light
does not come on after the ignition is
turned to on.
The “TRAC OFF” indicator/warning light
is left on after the ignition is turned to
on.
The “TRAC OFF” indicator/warning light
comes on while driving without pushing
“TRAC OFF” switch.(n) Low Windshield Washer Fluid Level
Warning Light
The light warns that the windshield washer
fluid level is too low. Add washer fluid at
your earliest opportunity. (For instructions,
see “Adding washer fluid” in Section 7−3.)
(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.
(p) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver’s door with
the ignition key in the “ACC” or “LOCK”
position.

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.
