The SRS (Supplemental Restraint Sys-
tem) airbags are designed to provide
further protection to the driver and
front passenger when added to the pri-
mary protection provided by the seatbelts.
In response to a severe frontal impact, the
SRS airbags work together with the seat
belt to help preventing or reduce injury by inflating, in order to decrease the likeli-
hood of the driver's or front passenger's
head or chest directly hitting the steering
wheel or dashboard. The passenger air-
bag is activated even with no passenger
in the front seat.This indicator comes on when the
ignition key is turned to the ACCº or
ONº position. It goes off after about 6
seconds. This means the SRS airbag
is operating properly.
The SRS airbag warning light system
monitors the airbag sensor assembly, in-
flators, warning light, interconnecting wir-
ing and power sources.The SRS airbag system is designed to
activate in response to a severe frontal
impact within the shaded area be-
tween the arrows in the illustration.
The SRS airbags will deploy if the severity
of the impact is above the designed
threshold level, comparable to an approxi-
mate 20 km/h (14 mph) collision when im-
pacting straight into a fixed barrier that
does not move or deform.
If the severity of the impact is below the
above threshold level, the SRS airbags
may not deploy.

However, this threshold velocity will be
considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign
pole, which can move or deform on im-
pact, or if it is
involved in an underride col-
lision (e.g. a collision in which the noise of
the vehicle underridesº, or goes under, the bed of a truck). It is possible with collision severity at the marginal level of airbag sensor detection
and activation that only one of your ve-
hicle's two airbags will deploy. For your safety of all occupants, be sure to always wear seat belts.
The SRS airbags are not designed to inflate if the vehicle is subjected to a
side or rear impact, if it rolls over, or if
it is involved in a low-speed frontalcollision.The SRS airbag system mainly consists
of the following components and their
locations are shown in the illustration.
1 SRS airbag warning light.
2 Steering wheel pad (airbag and inflat- or)
3 Passenger airbag module (airbag and inflator)
4 Airbag sensor assembly.
The airbag sensor assembly consists of a
safing sensor and airbag sensor.

The gauge works when the ignition
switch is on and indicates the approxi-
mate quantity of fuel remaining in the tank. Nearly fullÐNeedle at Fº Nearly emptyÐNeedle at Eº
It is a good idea to keep the tank over 1/4 full.
This fuel gauge has a non-return type
needle wh ich remains at the last indicated
position when the ignition switch is turned
off.
If the fuel level approaches Eº or the low fuel level warning light comes on, fill the fuel tank as soon as possible. If the fuel tank is completely empty, the malfunction
indicator lamp comes on. Fill
the fuel tank immediately.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer assoon as possible.

(a) Brake System Warning Light This light has the following functions: Parking brake reminder
If this light is on, make sure the parking
brake is fully released. The light should go
off.
Low brake fluid level warning
If this light comes on and stays on while
you are driving, slow down and pull off the
road. Then stop the vehicle carefully.There may be a problem somewhere in
the brake system. Check the fluid level of
the see-through reservoir.
To make sure the parking brake has not
caused the warning light to come on,
check to see that the parking brake is fully
released.
If the brake fluid level is low...
At a safe place, test your brakes by start-
ing and stopping. If you judge that the brakes still work
adequately, drive cautiously to yournearest dealer or shop for repairs.
If the brakes are not working, have the
vehicle towed in for repairs. (For tow-
ing information, see Part 4.)
It is dangerous to continue driving
normally when the brake fluid level
is low. CAUTION
!
If the brake fluid level is correct...
Have the warning system checked by
your Toyota dealer.
(b) Seat Belt Reminder Light and Buzzer
Once the ignition key is turned to ONº or
STARTº, the reminder light and buzzer
come on if the driver's seat belt is not fas-
tened. Unless the driver fastens the belt,the light stays on and the buzzer sounds for about 4 to 8 seconds.
(c) 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, ra dio, etc., and drive directly to the
nearest Toyota dealer or repair shop.

67
NOTICE
Do not continue driving if the engine drive belt is broken or loose.
(d) 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 driv-
ing, pull off the road to a safe place and
stop the engine immediately. Call a Toyo-
ta dealer or qualified repair shop for assis- tance.
The light may occasionally flicker when
the engine is idling or it may come on brief-
ly after a hard stop. There is no cause for concern if it then goes out when the en-
gine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to indi-cate low oil level, and the oil level must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the warning light onÐeven for one
block. It may ruin the engine.
(e) Malfunction Indicator Lamp
This lamp comes on in the following cases.
a. The fuel tank is completely empty. (See Fuel gaugeº in Chapter 1-5 for in- structions.)
b. The fuel tank cap is not tightened se-
curely. (See Fuel tank capº in Chapter
1-2 for instructions.)
c. There is a problem somewhere in your engine or automatic transmission
electrical system.
If it comes on while you are driving in case
c, have your vehicle checked/repaired 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.
(g) ABSº Warning Light
This light warns that there is a problem
somewhere in your anti-lock brake sys-tem.
If the light comes on while you are driving,
have your vehicle checked by your T oyota
dealer as soon as possible. The light will come on when the ignition
key is turned to the ONº position. After
about 3 seconds, the light will go off. When the ABSº warning light is on (and
the brake system warning light is off), the brake system
operates conventionally but
anti-lock brake system is not assisting brake performance so that the wheels can
lock-up during sudden braking or braking
on slippery road surfaces.
(h) Open Door Warning Light
This light remains on until all the doors
and back door are completely closed.
(i) SRS Airbag Warning Light
This light will come on when the igni-
tion key is turned to the ACCº or ONº
position. After about 6 seconds, the
light w ill go off. This means the airbag
system is operating properly.
The warning light system monitors the air-
bag sensor assembly, inflators, warning
light, interconnecting wiring and power sources.

68If 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 light does not come on when the
ignition key is turned to the ACCº or
ONº position or remains on.
The light comes on while driving.
(j) Light Reminder Buzzer
This buzzer will sound if the driver's door is opened while the ignition switch is turned to the LOCKº position with the
headlight switch on. Removing the key will
not stop the buzzer as long as the head-light switch is on.
(k) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver's door with the ignition key in the ACCº or LOCKº position.
(l) Unengaged Parkº Warning Light
(vehicles with automatic transmis-sion)
This light warns that the transmission
Parkº mechanism is not engaged. If the
front drive control lever is in the Nº posi-
tion while the selector lever is in the Pº
position, the transmission will disengage
and the wheels will not lock.
To restore the park function, shift
the front drive control lever out of
Nº, or the vehicle can move. CAUTION
!
(m) Automatic Transmission Fluid
Temperature Warning Light
This light warns that the automatic trans- mission fluid temperature is too high.
If this light comes on while you are driving,
slow down and pull off the road. Stop the
vehicle at a safe place and put the selector
lever in Pº. With the engine idling, wait
until the light goes off. If the light goes off,
you may start the vehicle again. If the light
does not go off, call a Toyota dealer or
qualified repair shop for assistance.
NOTICE
Continued driving with the warning light on may damage the automatic
transmission.
(n)Low Windshield Washer Fluid Level
Warning Light (Canada)
The light warns that the windshield wash-
er fluid level is too low. Add washer fluid at
your earliest opportunity. (For instruc-
tions, see Adding washer fluidº in Chap-ter 7-3.)
CHECKING SERVICE REMINDER INDI-
CATORS
1. Apply the parking brake.
2. Open one of the side doors or the back
door.
The open door warning light should come on.
3. Close the door. The open door warning light should go
off.
4. Turn ignition key to ACCº. The SRS airbag warning light should
come on. It goes off after about 6 sec-onds.
5. Turn the ignition key to ONº, but do not start the engine.
All the service reminder indicators ex-
cept the open door warning light and
SRS airbag warning light should come
on. The ABSº warning light goes off
after about 3 seconds.

Your engine is fitted with twin ground electrode spark plugs.
NOTICE
Use only twin ground electrode spark plugs for your engine perfor-
mance.
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 fa il, the other will 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 nomore!
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
normal. And your braking dis- tance will be longer
ANTI-LOCK BRAKE SYSTEM (with ABSº warning light)
The anti- lock brake system is designed to
automatically help prevent lock- up of the
wheels during sudden braking or braking on
slippery road surfaces. This assists in pro-
viding directional stability and steering per -
formance of the vehicle under these cir -
cumstances.
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 approximate-
ly 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 thebrake 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 capab ility 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 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 antilockbrake system from operating at fulleffictiveness.
Vehicles with rear differential lock sys-
temÐThe anti-lock brake system does
not operate when the rear differential islocked. It is normal operation for the
ABSº warning light to be on at this time.Type A
