UPFITTER CONTROLS (IF EQUIPPED)
Your vehicle may be equipped with
the Upfitter option package which
will provide four switches, mounted
in the center of the instrument
panel, labeled AUX 1, AUX 2, AUX 3
and AUX 4. These switches will only
operate while the ignition is in the
on position, whether the engine is
running or not. It is, however, recommended that the engine remain
running to maintain battery charge when using the Upfitter switches for
extended duration or higher current draws. (This is even more important
for vehicles with diesel engines since the glow plugs are also draining
battery power when the ignition key is in the on position.)
When switched on by the operator they provide 8 amps, 12 amps or
20 amps of electrical battery power for a variety of personal or
commercial uses.
If your vehicle is equipped with this option, there will also be a relay box
located on the driver side end of the instrument panel. See your
authorized dealer for service.
The relays are coded as shown in
the accompanying illustration. RELAY

WARNING: Never place your arm over the airbag module as a
deploying airbag can result in serious arm fractures or other
injuries.
To properly position yourself away from the airbag:
• Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
• Recline the seat slightly one or two degrees from the upright position.
WARNING: Do not put anything on or over the airbag module.
Placing objects on or over the airbag inflation area may cause
those objects to be propelled by the airbag into your face and torso
causing serious injury.
WARNING: Do not attempt to service, repair, or modify the
airbag supplemental restraint systems or its fuses. Contact your
authorized dealer as soon as possible.
WARNING: The front passenger airbag is not designed to offer
protection to an occupant in the center front seating position.
WARNING: Modifying or adding equipment to the front end of
the vehicle (including frame, bumper, front end body structure
and tow hooks) may affect the performance of the airbag system,
increasing the risk of injury. Do not modify the front end of the
vehicle.
WARNING: Additional equipment such as snowplow equipment
may effect the performance of the airbag sensors increasing the
risk of injury. Please refer to the Body Builders Layout Book for
instructions about the appropriate installation of additional equipment.
Children and airbags
For additional important safety information, read all information on
safety restraints in this guide.
Children must always be properly restrained. Failure to follow these
instructions may increase the risk of injury in a collision. Seating and Safety Restraints

• Safety Canopy  System (if equipped). Refer to Safety Canopy 
System later in this chapter.
• one or more impact and safing sensors,
• a readiness light and tone
• and the electrical wiring which connects the components.
The diagnostic module monitors its own internal circuits and the
supplemental airbag electrical system wiring (including the impact
sensors), the system wiring, the airbag system readiness light, the airbag
backup power and the airbag ignitors.
Seat-mounted side airbag system (if equipped)
WARNING: Do not place objects or mount equipment on or
near the airbag cover on the side of the seatbacks of the front
seats or in front seat areas that may come into contact with a
deploying airbag. Failure to follow these instructions may increase the
risk of personal injury in the event of a collision.
WARNING: Do not use accessory seat covers. The use of
accessory seat covers may prevent the deployment of the side
airbags and increase the risk of injury in an accident.
WARNING: Do not lean your head on the door. The side airbag
could injure you as it deploys from the side of the seatback.
WARNING: Do not attempt to service, repair, or modify the
airbag SRS, its fuses or the seat cover on a seat containing an
airbag. See an authorized dealer.
WARNING: All occupants of the vehicle should always wear
their safety belts even when an airbag SRS is provided.Seating and Safety Restraints

The fact that the airbags did not inflate in a collision does not mean that
something is wrong with the system. Rather, it means the forces were not of
the type sufficient to cause activation. Side airbags are designed to inflate in
side-impact collisions, not roll-over, rear-impact, frontal or near-frontal
collisions, unless the collision causes sufficient lateral deceleration.
WARNING: Several airbag system components get hot after
inflation. Do not touch them after inflation.
WARNING: If the side
airbag has deployed, the
airbag will not function again.
The side airbag system
(including the seat) must be
inspected and serviced by an
authorized dealer. If the airbag
is not replaced, the unrepaired
area will increase the risk of injury
in a collision.
Safety Canopy  System (if equipped)
WARNING: Do not place
objects or mount equipment
on or near the headliner at the
siderail that may come into contact
with a deploying Safety Canopy  .
Failure to follow these instructions
may increase the risk of personal
injury in the event of a collision.
WARNING: Do not lean your head on the door. The Safety
Canopy  could injure you as it deploys from the headliner.
WARNING: Do not attempt to service, repair, or modify the
Safety Canopy  System, its fuses, the A, B, or C pillar trim, or
the headliner on a vehicle containing a Safety Canopy  . Contact your
authorized dealer as soon as possible.Seating and Safety Restraints

The Safety Canopy system, in combination with safety belts, can help
reduce the risk of severe injuries in the event of a significant side impact
collision or rollover event.
Children 12 years old and under should always be properly restrained in
the second row seats. The Safety Canopy will not interfere with children
restrained using a properly installed child or booster seat because it is
designed to inflate downward from the headliner above the doors along
the side window opening.
The Safety Canopy system is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the RCM to initiate Safety
Canopy inflation or when a certain likelihood of a rollover event is
detected by the rollover sensor.
The Safety Canopy is mounted to roof side-rail sheet metal, behind the
headliner, above each row of seats. The Safety Canopy is designed to
inflate between the side window area and occupants to further enhance
protection provided in side impact collisions and rollover events.
The fact that the Safety Canopy did not activate in a collision does not
mean that something is wrong with the system. Rather, it means the
forces were not of the type sufficient to cause activation. The Safety
Canopy is designed to inflate in certain side impact collisions or rollover
events, not in rear impact, frontal or near-frontal collisions, unless the
collision causes sufficient lateral deceleration or rollover likelihood.
WARNING: Several Safety
Canopy system components
get hot after inflation. Do not
touch them after inflation.
WARNING: If the Safety Canopy system has deployed, the
Safety Canopy will not function again unless replaced. The
Safety Canopy system (including the A, B, C, and D pillar trim and
headliner) must be inspected and serviced by an authorized dealer. If
the Safety Canopy is not replaced, it will not function again, which will
increase the risk of injury in a future collision.Seating and Safety Restraints

Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to Warning lights and
chimes in the Instrument Cluster chapter. Routine maintenance of the
side airbag is not required.
A difficulty with the system is indicated by one or more of the following:
• The readiness light (same light as for front airbag system) will either
flash or stay lit.
• The readiness light will not illuminate immediately after ignition is
turned on.
• A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your authorized dealer immediately. Unless serviced, the system may
not function properly in the event of a collision.
SOS Post-Crash Alert System™
The system automatically flashes the turn signal lamps and sounds the
horn three times at four second intervals in the event of a serious impact
that deploys an airbag (front, side, side curtain [if equipped] or Safety
Canopy  [if equipped]) or the safety belt pretensioners.
The system can be turned off when any one of the following actions are
taken by the driver or any other person:
• pressing the hazard control button,
• or pressing the panic button on the remote entry transmitter.
The feature will continue to operate until the vehicle runs out of power. Seating and Safety Restraints
