3. OPERATING CONDITIONS
A. Front Air Bag System
The air bag does not deploy when: ▶The air bag deploys when: ▶
The air bag can deploy when: ▶A front collision occurs, which occupants cannot be protected by seat belt. -
The vehicle rolls over or tips over sideward, or a side/rear collision occurs.
the impact of the collision is low enough for the seat belt to protect the occupant properly. -
-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. -
Seldom oeprate ▶
A collision to diagonal direction (not a front collision) occurs or the vehicle tips over.
A weak collision, which the sensor cannot detect, occurs (under the activation requirements).
A collision against narrow objects such as a telegraph pole or a tree occurs.
The vehicle falls into a drainage or a puddle.
The front of the vehicle crashes into high impact point vehicle such as a truck.
The hood is hit by falling stones.
The air bag warning lamp is on. -

As the air bag system is very hot after being deployed, allow at least 30 minutes for the system to cool
down sufficiently before touching it. It can cause serious burns.
When an occupant fastens the seat belt in an unstable or inclined posture, the air bag system cannot
protect the occupant properly. Moreover, the occupant can be injured by the air bag.
Children and infants should ride in a rear seat. Seating in the passenger's seat with carrying a child or
infant is strictly prohibited. An infant or a child could be severely injured by air bag deployed.
A child restraint system must be placed in a rear seat.
A child restraint system must not be placed in the passenger's seat. An infant or a child could be
severely injured by the air bag deployment.
Do not cover, place any object or affix any stickers on the air bag inflation location.
Do not cover the front seat. The side air bag will not work properly.
Never put your arms around the front seat from behind, lean on the front seatback, or put your arms
out of the window. You can severely injured when the side air bag deploys.
Never lean on the door since it becomes very dangerous when the side air bag deploys.
Do not put any object such as an umbrella or bags between the door and side air bag mounting.
The side air bag deploys when there is a severe side collision.
Do not put any object such as an umbrella or bags between the door and side air bag mounting.
Do not slam the front door to close it. The side air bag may deploy unexpectedly.
Do not move your seat too close to the steering wheel or dashboard. Being too close to the steering
wheel or instrument panel during the air bag deployment could cause serious injury, including death
Move back as far as practical to allow the air bag room to inflate when driving.
Do not incline toward the steering wheel or hold the steering wheel with your hands crossed. Never
allow the front passenger to put hands or feet on the dash board. It can cause severe injures when
the air bag inflates.
Never put your feet on the dash board. You can severely injured when the air bag inflates.
It is normal that a loud noise, dust and smoke occur when the air bag and seat belt pretensioner
operate.
A large quantity of non-toxic gas is generated when the air bag or seat belt pretensioner deploys. If
these airborne particles irritate your skin, eyes, nose, or throat, rinse the area with cool water. If the
irritation continues, see your doctor.
The windshield glass may be broken when the passenger air bag deploys.
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.
A loud noise and non-toxic smoke-like particles are generated when air bags deploy. -

Occurs
2) Side Air Bag Operating Conditions When A Side Impact Occurs
Impact to Left direction Right direction
Seat belt pretensioner - Driver side IGN IGN
Seat belt pretensioner - Passenger side IGN IGN
Side air bag module - Passenger side IGN Not ignite
Side air bag module - Passenger side Not ignite IGN
Inflatable curtain air bag module - Driver side IGN Not ignite
Inflatable curtain air bag module - Passenger side Not ignite IGN

Seat belt pretensioner - Driver side IGN
Seat belt pretensioner - Passenger side IGN
Once the ignition starts, the SDM starts to diagnose the air bag system during the ignition process.
If the system is OK, the SDM is armed for a specific impact on the vehicle. The ignition time takes about
6 sec.

2) Air Bag Deployment Signal Output (Crash Out)
When a situation which requires air bag deployment occurs, they system outputs the air bag deployment
signal (crash out). If another air bag-required situation occurs while the deployment signal is sent, the
second crash out will be delayed until the current 200 ms crash out is completed. (The tolerance at the
time of signaling is ±5%)
The signal repeats increasing for 390 msec. and decreasing for 10 msec. before crash. At the time of
crash, the switch is closed and the signal is kept low condition for 200 msec.
At the time of crash, the crash out signal is changed to the low condition for 200 ms immediately to
indicate the crash moment.

3) CAN Communication Interface (FIS and SIS)
The CAN communication interface uses the PWM for the supply current and the current loop and
communicates with the SDM to transmit the information. The serial communication and power for the
satellite are supplied through the communication line.
Stage FIS SIS
Initial stage Tracking/Check (Self test) Same as FIS
Normal operation Checks the FIS condition and sends the result as
"OK" or "NOK", and also sends the "severity" of the
crash. Same as FIS
Voltage The FIS hardware reset was performed under 5 V,
communication voltage low Same as FIS
Fault The fault is found in the current ignition cycle but the
fault is deactivated in the next ignition cycle. Multiple faults can be found
and deactivated in the same
ignition cycle.
The FIS moves to the initial stage if 'leakage to GND' is occurred in normal operating stage to shut down
the power and prevent abnormal operation.
※ FIS: Front Impact Sensor
SIS: Side Air bag Sensor

4. AIR BAG WARNING LAMP OPERATIONAL CONDITIONS
When there are no active and past faults ▶
The air bag warning lamp is operated as shown below if there is no fault occurred in the previous ignition
cycle and the SDM is running without any active fault right after starting the ignition cycle.
When there is no active fault and past faults occurred less than 10 times ▶
The warning lamp is operated as shown below every time the vehicle is started if the SDM is running
without any active fault in the entire time and past faults in the previous ignition cycle occurred within 10
times.
"Battery voltage too low" is not included in the past faults.

04-8
5) Emergency Operation
If the sunroof becomes out of order while it is
open or tilted, the sunroof can be operated
through the motor operating hole of the sunroof
motor.
When you drive this vehicle with the window or sunroof open at a certain position, you may feel
some pressure upon your ears or hear some noises similar to those from a helicopter. This happens
because of an influx in air through the window or sunroof and its resonance effect. If this happens,
adjust by opening the window or sunroof. - The anti-pinch function is deactivated just before the sunroof closes.
The sunroof safety function is just a safety supplementary system which cannot replace driver's care
and caution. Moreover, it may not be able to operate due to electric part or other conditions. To prevent any body parts from being trapped by the sliding sunroof, an Anti-Pinch Function
automatically opens the sunroof when an object is trapped.
