1999 TOYOTA COROLLA warning light

C orolla (U)
38
The SRS airbag system mainly consists of
the following components and their loca-
tions are shown in the illustration.
1. Front airbag sensors
2. SRS airbag warning light
3. Airbag module for passenger (airbag
and inflator)
4. Airbag sensor assembly
5. Airbag module for driver (airbag and
inflator)
The airbag sensor assembly consists of a
safing sensor and airbag sensor.In a severe frontal impact, sensors detect
deceleration and the system triggers the
airbag inflators. Then a chemical reaction
in the inflators momentarily fills the air-
bags with non- toxic gas to help restrain
the forward motion of the occupants.
When the airbags inflate, they produce a
fairly loud noise and release some smoke
and residue along with non- toxic gas. This
does not indicate a fire. This gas is nor-
mally harmless, however, for those who
have delicate skin, it may cause minor
skin irritation. Be sure to wash off any
residue as soon as possible to prevent
minor skin irritation.
Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is designed to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swellings.
Parts of the airbag module (steering wheel
hub, dashboard) may be hot for several
minutes, but the airbags themselves will
not be hot. The airbags are designed to
inflate only once.A crash severe enough to inflate the air-
bags may break the windshield as the
vehicle buckles. In vehicles with a pas-
senger airbag the windshield may also be
damaged by absorbing some of the force
of the inflating airbag.

SRS side airbags
The SRS (Supplemental Restraint Sys-
tem) side airbags are designed to pro-
vide further protection for the driver
and front passenger when added to the
primary protection provided by the seat
belts.
In response to a severe side impact, the
SRS side airbags work together with the
seat belt to help prevent or reduce injury
by inflating, in order to decrease the im-
pact mainly on the driver's or front pas-
senger 's chest. The SRS side airbag on
the passenger seat is activated even with
no passenger in the front seat.
CAUTION
SRS side airbags inflate with consid-
erable force. To avoid potential death
or serious injury during inflation of a
side airbag, Toyota strongly recom-
mends that the driver and front pas-
senger;

Wear their seat belt

Remain properly seated with their
back against the seat at all times.
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 side
airbags are operating properly.
The warning light system monitors the air-
bag sensor assembly, inflators, warning
light, interconnecting wiring and power
sources. (For details, see ºService remind-
er indicators and warning buzzersº in
Chapter 1- 5.)

The SRS side airbag system mainly con-
sists of the following components and
their locations are shown in the illustra-
tion.
1. SRS airbag warning light
2. Side airbag module (airbag and inflator)
3. Side airbag sensor assemblies
4. Airbag sensor assembly
The SRS side airbag system is controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.In a severe side impact, the side airbag
sensor triggers the side airbag inflators.
Then a chemical reaction in the inflators
momentarily fills the airbags with non- tox-
ic gas to help restrain the lateral motion
of the occupants.
When the airbags inflate, they produce a
fairly loud noise and release some smoke
and residue along with non- toxic gas. This
does not indicate a fire. This gas is nor-
mally harmless, however, for those who
have delicate skin, it may cause minor
skin irritation. Be sure to wash off any
residue as soon as possible to prevent
minor skin irritation.
Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is designed to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swellings.
Front seats may be hot for several min-
utes, but the airbags themselves will not
be hot. The airbags are designed to inflate
only once.
CAUTION

The SRS side airbag system is de-
signed only as a supplement to the
primary protection of the driver
side and front passenger side seat
belt systems. The front seat occu-
pants can be killed or seriously in-
jured by an inflating airbag if they
do not wear the available seat
belts. During sudden braking just
before a collision, an unrestrained
driver or front passenger can move
sideward into direct contact with or
close proximity to the airbag which
may then deploy during the colli-
sion. To obtain maximum protection
in an accident, the driver and all
passengers in the vehicle must
wear their seat belts. Wearing a
seat belt during an accident re-
duces the chances of death or seri-
ous injuries or being thrown out of
the vehicle. For instructions and
precautions concerning the seat
belt system, see ºSeat beltsº in this
chapter.

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.
This fuel gauge has a non- return type
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.

The light and buzzer remind you to buckle
up the driver 's seat belt.
Once the ignition key is turned to ºONº or
ºSTARTº, the reminder light flashes and
buzzer sounds if the driver 's seat belt is
not pulled out. Unless the driver starts to
pull the shoulder belt out of the retractor,
the light keeps flashing and the buzzer
stops after 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, 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.
(d) 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.(e) 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.
(f) 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.

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 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, 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.

The light comes on while driving.
