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 airbag
sensor assembly, seat belt pretensioner
assembly, warning light, interconnecting
wiring and power sources. (For details,
see ºService remainder 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 sensor
2. SRS airbag warning light
3. Seat belt pretensioner assembly
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 death or serious personal inju-
ry.
Failure to follow these instructions
can result in death or serious inju-
ries.

This front seat belt pretensioner system
has a service reminder indicator to inform
the driver of operating problems. If either
of the following conditions occurs, this
indicates a malfunction of the airbags or
pretensioners. 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.
The light comes on or flashes while

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.
The SRS airbag warning light system
monitors the airbag sensor assembly, in-
flators, warning light, interconnecting wir-
ing and power sources. (For details, see
ºService remainder indicators and warning
buzzersº in Chapter 1- 5.)The SRS airbag system is designed to
activate in response to a severe frontal
impact within the shaded area between
the arrows in the illustration.
There may be the case that the SRS air-
bags will not activate with such an impact
in which the occupant wearing the seat
belt correctly would not get serious injury.
The SRS airbags will deploy if the severi-
ty of the impact is above the designed
threshold level, comparable to an approxi-
mate 25 km/h (15 mph) collision when
impacting 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
impact, or if it is involved in an underride
collision (e.g. a collision in which the nose
of the vehicle ºunderridesº, or goes under,
the bed of a truck, etc.).
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 the safety of all occupants, be sure
to always wear seat belts.

This SRS airbag system has a service
reminder indicator to inform the driver of
operating problems. If either of the follow-
ing conditions occurs, this indicates a mal-
function of the airbags. Contact your
Toyota dealer as soon as possible to ser-
vice the vehicle. The light does not come on when the
ignition key is turned to the ºACCº or
ºONº position, or remains on.
The light comes on while driving.
NOTICE

accident not of the extent to cause the
SRS airbags to inflate.
The pad section of the steering wheel
or front passenger airbag cover
(shaded in the illustration) is scratched,
cracked, or otherwise damaged.

needle which remains at the last indicated
position when the ignition switch is turned
off.
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.

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.

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
pretensioners are operating properly.
The warning light system monitors the air-
bag sensor assembly, seat belt pretension-
er 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 ºACCº or
ºONº position or remains on.
