2. OPERATING RANGE
In the event of the collision, the air bag will be deployed when the G value detected by the G
sensor in the SDM is beyond the impact limit. ▶
Seat Belt Status Air Bag OperationSeat Belt Pretensioner Operation
Fastened Over reference speed Below reference speed
Unfastened Below reference speed Inoperative
Failure, during initial
diagnosisBelow reference speed Below reference speed
No sensor Below reference speed Below reference speed
This is based on frontal collision and reference speed is between approx. 4 and 24 km/h. *
The air bag is deployed in the event of frontal collisions while drving.
But, there are exceptional cases as follows: ▶
Situation Condition
May operate or not
Never operate
Seldom oeprate
Underbody impact from the road surface, impact against the curb at a
very high speed, or dropping impact onto the road surface with a
large angle occurs.
The vehicle rolls over or tips over sideward by severe impact. -
-
A collision with oblique impact to the front seat direction or a front collision
to the diagonal direction occurs.
A front/rear collision occurs.
The vehicle rolls over or tips over sideward with minor impact.
The air bag warning lamp is on. -
-
-
-The vehicle is stationary or a front collision occurs with low speed.
A rear collision occurs.
A minor collision occurs. -

The windshield or windows can be broken due to impact from driver or passenger air bag
inflation.
When any repairs are needed to the air bag mounting area or its surrounding area, or when an
accident has occurred without the air bag deployment, have the air bag system/seat belt
pretensioner checked for safety.
The air bag is a unit to save an occupant's life from sudden accident and it inflates at a very fast
speed by gas with high temperature, which might cause injury, such as an abrasion, bruise and
burn depending on the accident conditions.
Normal inflation of the air bag could make a loud noise and smoke (non-toxic gas).
A minor collision, which occupants can be protected only by seat belts, will not activate the air bag
system. It is because that air bag inflation at a minor collision could cause more injury such as an
abrasion, bruise and burn.
Check the air bag system even though there is no fault in the air bag system when 10 years have
passed after air bag installation. -

5. AIR BAG WARNING LAMP OPERATIONAL CONDITIONS
The air bag warning lamp on the instrument panel has a few operational conditions. The following are
the conditions:
When Turning the Ignition Switch to ON Position Initially ▶
The air bag unit performs a turn-on test when the ignition is turned on initially. The air bag unit flashes the
air bag warning lamp 6 times at 1 Hz interval. After that, the air bag warning lamp will go off if no
malfunction have been detected.
When the Air Bag Unit Detects Any Malfunctions in Unit ▶
When the Air Bag Unit Detects Any Intermittent Failure ▶ When it is recorded as a system failure in the air bag unit, the air bag warning lamp on the instrument
panel comes on for about 6 seconds and goes off for 1 second. Then the waning lamp stays on.
When, due to an error from outside the system, the intermittent failure signal is received 5 times or less,
the air bag warning lamp comes on for about 6 seconds and then, goes off.
