Front Air Bag Operation

Front Air Bags are designed to provide additional
protection by supplementing the seat belts. Front
air bags are not expected to reduce the risk of
injury in rear, side, or rollover collisions. The front
air bags will not deploy in all frontal collisions,
including some that may produce substantial
vehicle damage — for example, some pole
collisions, truck underrides, and angle offset
collisions.

On the other hand, depending on the type and
location of impact, front air bags may deploy in
crashes with little vehicle front-end damage but
that produce a severe initial deceleration.
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and
damage by themselves are not good indicators
of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection in
all collisions, and also are needed to help keep
you in position, away from an inflating air bag.
When the Occupant Restraint Controller (ORC)
detects a collision requiring the front air bags, it
signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air
bags.

The steering wheel hub trim cover and the
upper passenger side of the instrument panel
separate and fold out of the way as the air bags
inflate to their full size. The front air bags fully
inflate in less time than it takes to blink your
eyes. The front air bags then quickly deflate
while helping to restrain the driver and front
passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the
knees of the driver and front passenger, and
position the front occupants for improved
interaction with the front air bags.
WARNING!
No objects should be placed over or near
the air bag on the instrument panel or
steering wheel because any such objects
could cause harm if the vehicle is in a colli
-
sion severe enough to cause the air bag to
inflate.

Do not put anything on or around the air bag
covers or attempt to open them manually.
You may damage the air bags and you could
be injured because the air bags may no
longer be functional. The protective covers
for the air bag cushions are designed to open
only when the air bags are inflating.

Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain you
properly. In some collisions, air bags won’t
deploy at all. Always wear your seat belts
even though you have air bags.
WARNING!
Do not drill, cut, or tamper with the knee
impact bolsters in any way.
Do not mount any accessories to the knee
impact bolsters such as alarm lights,
stereos, citizen band radios, etc.

SOS Call

1. Push the SOS Call button on the overhead console.

NOTE:
In case the SOS Call button is pushed in error,
there will be a 10 second delay before the SOS
Call system initiates a call to a SOS operator.
To cancel the SOS Call connection, push the
SOS call button on the overhead console or
press the cancellation button on the Device
Screen. Termination of the SOS Call will turn off
the green LED light on the overhead console.
2. The LED light located within the ASSIST and SOS buttons on the overhead console will
turn green once a connection to a SOS
operator has been made.
3. Once a connection between the vehicle and a
SOS operator is made, the SOS Call system
may transmit the following important vehicle
information to a SOS operator:
Indication that the occupant placed a
SOS Call.
The vehicle brand.
The last known GPS coordinates of the
vehicle.
4. You should be able to speak with the SOS operator through the vehicle audio system
to determine if additional help is needed. NOTE:
Your vehicle may be transmitting data as
authorized by the subscriber.
Once a connection is made between the
vehicle’s SOS Call system and the SOS oper
-
ator, the SOS operator may be able to open a
voice connection with the vehicle to deter -
mine if additional help is needed. Once the
SOS operator opens a voice connection with
the vehicle’s SOS Call system, the operator
should be able to speak with you or other
vehicle occupants and hear sounds occurring
in the vehicle. The vehicle’s SOS Call system
will attempt to remain connected with the
SOS operator until the SOS operator termi -
nates the connection.
5. The SOS operator may attempt to contact appropriate emergency responders and
provide them with important vehicle
information and GPS coordinates.
WARNING!

ALWAYS obey traffic laws and pay attention
to the road. ALWAYS drive safely with your
hands on the steering wheel. You have full
responsibility and assume all risks related to
the use of the features and applications in this
vehicle. Only use the features and applications

SOS Call System Limitations
Vehicles sold in Mexico DO NOT have SOS Call
system capabilities.
SOS or other emergency line operators in
Mexico may not answer or respond to SOS
system calls.
If the SOS Call system detects a malfunction,
any of the following may occur at the time the
malfunction is detected, and at the beginning of
each ignition cycle:
The overhead console light located within the
ASSIST and SOS buttons will continuously
illuminate red.
The Device Screen will display the following
message: “Vehicle device requires service.
Please contact an authorized dealer.”
An In-Vehicle Audio message will state
“Vehicle device requires service. Please
contact an authorized dealer.”
WARNING!
If anyone in the vehicle could be in danger
(e.g., fire or smoke is visible, dangerous
road conditions or location), do not wait for
voice contact from an Emergency Services
Agent. All occupants should exit the vehicle
immediately and move to a safe location.
Never place anything on or near the
vehicle’s operable network and GPS
antennas. You could prevent operable
network and GPS signal reception, which
can prevent your vehicle from placing an
emergency call. An operable network and
GPS signal reception is required for the SOS
Call system to function properly.
The SOS Call system is embedded into the
vehicle’s electrical system. Do not add
aftermarket electrical equipment to the
vehicle’s electrical system. This may
prevent your vehicle from sending a signal
to initiate an emergency call. To avoid inter -
ference that can cause the SOS Call system
to fail, never add aftermarket equipment
(e.g., two-way mobile radio, CB radio, data
recorder, etc.) to your vehicle’s electrical
system or modify the antennas on your
vehicle. IF YOUR VEHICLE LOSES BATTERY
POWER FOR ANY REASON (INCLUDING
DURING OR AFTER AN ACCIDENT), THE
UCONNECT FEATURES, APPS AND
SERVICES, AMONG OTHERS, WILL NOT
OPERATE.
Modifications to any part of the SOS Call
system could cause the air bag system to
fail when you need it. You could be injured
if the air bag system is not there to help
protect you.
