This indicator comes on when the igni-
tion key is turned to the ºACCº or
ºONº position. It goes off after about
6 seconds. This means the front seat
belt pretensioners are operating proper-
ly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, seat belt pretensioner assemblies,
warning light, interconnecting wiring and
power sources. (For details, see ºService
reminder indicators and warning buzzersº
in Chapter 1- 5.)The seat belt pretensioner system mainly
consists of the following components and
their locations are shown in the illustra-
tion. 1. Front airbag sensors
2. SRS airbag warning light
3. Seat belt pretensioner assemblies
4. Airbag sensor assembly
The seat belt pretensioner is controlled by
the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor. When a seat belt pretensioner is acti-
vated, an operating noise may be heard
and a small amount of smoke- like gas
may be released. This gas is harmless
and does not indicate that a fire is occur-
ring.
Once the seat belt pretensioner has been
activated, the seat belt retractor remains
locked.
CAUTION
Do not modify, remove, strike or open
the front seat belt pretensioner as-
semblies, airbag sensor or surround-
ing area or wiring. Doing any of
these may cause sudden operation of
the front seat belt pretensioners or
disable the system, which could re-
sult in serious injury.
Failure to follow these instructions
can result in serious injuries.

The SRS (Supplemental Restraint Sys-
tem) airbags are designed to provide
further protection for the driver and
front passenger when added to the pri-
mary protection provided by the seat
belts.
In response to a severe frontal impact,
the SRS airbags work together with the
seat belts to help prevent 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 airbag
is activated even with no passenger in the
front seat.
Be sure to wear your seat belt.
CAUTION
A driver or front passenger too close
to the steering wheel or dashboard
during airbag deployment can be
killed or seriously injured. Toyota
strongly recommends that: The driver sit as far back as pos-
sible from the steering wheel while
still maintaining control of the ve-
hicle.
The front passenger sit as far back
as possible from the dashboard.
All vehicle occupants be properly
restrained using the available seat
belts.
This indicator comes on when the igni-
tion key is turned to the ºACCº or
ºONº position. It goes off after about
6 seconds. This means the SRS airbags
are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, inflators, warning light, interconnect-
ing wiring and power sources. (For details,
see ºService reminder indicators and
warning buzzersº in Chapter 1- 5.)

OPERATION OF
INSTRUMENTS AND
CONTROLSÐ
Chapter 1- 5
Gauges, Meters and
Service reminder indicators
Fuel gauge
Engine coolant temperature gauge
Tachometer
Odometer and two trip meters
Service reminder indicators and
warning buzzers
Fuel gauge
The gauge works when the ignition
switch is on and indicates the approxi-
mate quantity of fuel remaining in the
tank.
Nearly fullÐNeedle at ºFº
Nearly emptyÐNeedle at ºEº
It is a good idea to keep the tank over
1/4 full.
If the fuel level approaches ºEº or the low
fuel level warning light comes on, fill the
fuel tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the fuel gauge
needle may fluctuate or the low fuel level
warning light may come on earlier than
usual.
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 as
soon as possible.

Odometer and two trip meters
This meter displays the odometer and
two trip meters.
1. OdometerÐIt shows the total distance the vehicle has been driven.
2. Two trip metersÐThey show two differ- ent distances independently driven
since the last time each trip meter was
set to zero.
You can use one trip meter to calculate
the fuel economy and the other to
measure the distance on each trip. All
trip meter data is cancelled if the elec-
trical power source is disconnected.
3. Trip meter reset knobÐIt can reset the two trip meters to zero, and also
change the meter display. To change the meter display, quickly
push and release the knob. The meter
display changes in the order from the
odometer to trip meter A to trip meter
B, then back to the odometer each
time you push.
To reset the trip meter A to zero, dis-
play the meter A reading, then push
and hold the knob until the meter is
set to zero. The same process can be
applied for resetting the trip meter B.
If the indicator or
buzzer comes on...
(a) If parking brake is
off, stop and check.
(b) Fasten seat belts.
(d) Stop and check.
(e) Stop and check.
(f) Take vehicle to Toyota dealer.
(Indicator and buzzer)Do this.
(c) Fasten front passenger 's seat
belts.

(f) Malfunction Indicator Lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty. (See
ºFuel gaugeº in Chapter 1- 5 for instruc-
tions.)
b. The fuel tank cap is not tightened se-
curely. (See ºFuel 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/re-
paired by your Toyota dealer as soon as
possible.
(g) 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.
(h) ºABSº 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 driv-
ing, have your vehicle checked by your
Toyota dealer as soon as possible.
The light will come on when the ignition
key is turned to the ºONº position. After
a few seconds, the light will go off.
When the ºABSº 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.
Vehicles with rear differential lock sys-
temÐ
The anti- lock brake system does not oper-
ate when the rear differential is locked. It
is normal operation for the ºABSº warning
light to be on at this time.
(i) Open Door Warning Light
This light remains on until all the doors
and back door are completely closed.(j) SRS Airbag Warning Light
This light will come on when the igni-
tion key is turned to the ºACCº or
ºONº position. After about 6 seconds,
the light will go off. This means the
system of the airbag and front seat belt
pretensioner are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, seat belt pretensioner assemblies,
inflators, warning light, interconnecting wir-
ing 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 ºACCº or
ºONº position or remains on.

and the wheels will not lock.
CAUTION
To restore the park function, shift the
front drive control lever out of ºNº,
or the vehicle can move.
(m) Automatic Transmission Fluid Tem- perature Warning Light
This light warns that the automatic trans-
mission fluid temperature is too high.
If this light comes on while you are driv-
ing, slow down and pull off the road. Stop
the vehicle at a safe place and put the
selector lever in ºPº. With the engine id-
ling, 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.
