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 airbags
are operating properly.
The SRS airbag warning light system
monitors the front airbag sensors, center
airbag sensor assembly, inflators, warn-
ing light, interconnecting wiring 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 (a collision in which the nose 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, be sure to always wear your seat belts.

OPERATION OF INSTRUMENTS AND CONTROLSÐ
Chapter 1-5 Gauges, Meters and Service reminderindicators
Fuel gauge
Engine coolant temperature gauge
Tachometer
Odometer and two trip meters
Service reminder indicators and warning buzzers
The gauge works when the ignition
switch is on
and indicates the approxi-
mate quantity of fuel remaining in the tank.
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) Master Warning Light
This light warns that another service re-
minder indicator (except seat belt remind-
er light, low fuel level warning light, rear
light failure warning light, SRS airbag
warning light and TRAC OFFº indicator/warning light) is on.
If it comes on while you are driving, check
the other service reminder indicator that is
on with reference to the following descrip-
tion of the indicator.
(b) Brake System Warning LightThis 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 maybe 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.

53
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 your nearest 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.
(c) 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 stops af-
ter about 4 to 8 seconds.
(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 dischar-
ged. Turn off the air conditioning, blower,
radio, etc., and drive directly to the near-
est 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 gaugeº in Chapter 1-5 for in-structions.)
b. There is a problem somewhere in your
engine or automatic transmission electri- cal system.
If it comes on while you are driving in case
b, 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) 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 Toyota
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.
(h) Low Engine Oil Level Warning Light
The light warns that the engine oil level is
too low. Add oil as soon as possible. (For instructions, see Checking the engine oil
levelº in Chapter 7-2.)
NOTICE
Continued engine operation with low engine oil will damage the
engine.

54(i) 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), thebrake system operates conventionally but
without anti-lock function.
(j) Open Door Warning Light
This light remains on until both side doors
and back door are completely closed.
(k) Rear Light Failure Warning LightIf this light comes on when the headlight
switch is turned on (at the first or second
clickstop), it indicates that one or more ofthe tail lights are burned out.
If it comes on when the brake pedal is de-
pressed, one or more stop lights are
burned out or the stop light circuit is in
need of repair.
Have defective bulbs replaced as soon as
possible. (l) 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 will go off. This means the airbag
system is operating properly.
The warning light system monitors the
front airbag sensors, center airbag sensor
assembly, inflators, warning light, inter-
connecting wiring and power sources.
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 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.
(m) TRAC OFFº Indicator/Warning light
This light comes on when the ignition key
is turned to ONº, and will go off after 3
seconds. This means that the system is
operating properly. If one 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 remains on more than 3 sec- onds after the ignition switch is turned on.
The light comes on while driving evenif the TRAC OFFº switch is not pushed.
The light flashes.
(n) 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.
CHECKING SERVICE REMINDER INDI-
CATORS (except the low fuel level
warning light)
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 side door.
The open door warning light should go off.
4. Turn the 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.

55
All the service reminder indicators except the open door warning light and SRS air-
bag warning light should come on. The
ABSº
warning light and TRAC OFFº indi-
cator/warning light go off after about 3seconds.
If any service reminder indicator or warn-
ing buzzer does not function as described above, either the bulb is burned out or the
circuit is in need of repair. Have it checked
by your Toyota dealer as soon as pos-sible.

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.

111
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!
