1996 TOYOTA 4RUNNER airbag off

34
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 seatbelt to prevent or reduce injury by inflat- ing, in order to decrease the likelihood of
the driver's or front passenger's head or
chest directly hitting the steering wheel or dashboard. The passenger airbag is acti- vated even with no passenger in the frontseat.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 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.
SRS airbags

36In 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 nitrogen gas to help
restrain the forward motion of the occu-pants. When the airbags inflate, they produce a fairly
loud noise and release some smoke
along with the nitrogen gas. This is not harmful and does not indicate a fire. 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 forseveral minutes, but the airbags them- selves w ill not be hot. The airbags are de-
signed to inflate only once.
A crash severe enough to inflate the air-
bags may break the windshield as the ve-
hicle buckles. In vehicles with a passen- ger airbag the windshield may also be
damaged by absorbing some of the force
of the inflating airbag.
CAUTION!
The SRS airbag system is de-
signed only as a supplement to
the primary protection of the seat
belt systems of the driver and
front passenger. The front seat oc-
cupants are particularly suscepti-
ble to injury if they do not wear
their seat belts; when sudden
braking or a collision occurs, they
may be thrown forward. To obtain
further protection in an accident,
the driver and all passengers in
the vehicle should always wear
their seat belts when driving. For
instructions and precautions con-
cerning the seat belt system, see
Seat beltsº in this chapter.
A baby or small child who is too
small to use a seat belt should be
properly secured in a rear seat us-
ing a child restraint system.
Do not use a rear-facing child re-
straint system in the front seat be- cause the force of the rapid infla-
tion of the passenger airbag may cause severe injury to the child.
Vehicles with a passenger airbag
display a caution label on the pas-
senger side instrument panel as
shown above to remind you not to install a rear-facing child restraint
system on the front seat.

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 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.
(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 electri- cal 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
without anti-lock function.
(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.
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.

64(j) Light Reminder Buzzer
This buzzer will sound if the driver's door is opened while the ignition switch isturned 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. 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 Lev- el 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.
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.
