Front safety belt pretensioners
The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during frontal collisions, and in rollover and side collisions when the
Safety Canopy is activated. This helps increase the effectiveness of the
safety belts. In frontal collisions, the safety belt pretensioners can be
activated alone or, if the collision is of sufficient severity, together with
the front airbags.
Front safety belt energy management retractors
The front outboard safety belt energy management retractors allow
webbing to be pulled out of the retractor in a gradual and controlled
manner in response to the occupant’s forward momentum. This helps
reduce the risk of force-related injuries to the occupant’s chest by
limiting the load on the occupant. Refer toEnergy management feature
section in this chapter.
Determining if the Personal Safety System™ is operational
The Personal Safety System™ uses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to theWarning lightsection in theInstrument Clusterchapter.
Routine maintenance of the Personal Safety System™ is not required.
The Restraints Control Module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, driver seat
position sensor, and front passenger sensing system. In addition, the
RCM also monitors the restraints warning light in the instrument cluster.
A difficulty with the system is indicated by one or more of the following.
•The warning light will either flash or stay lit.
•The warning 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 warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety System™ serviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a
collision.

AIRBAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Important supplemental restraint system precautions
Airbags DO NOT inflate slowly or
gently and the risk of injury from a
deploying airbag is greatest close to
the trim covering the airbag module.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag
supplemental restraint system (SRS) is provided.
Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
National Highway Traffic Safety Administration (NHTSA)
recommends a minimum distance of at least 10 inches (25 cm)
between an occupant’s chest and the driver airbag module.

Never place your arm over the airbag module as a deploying
airbag can result in serious arm fractures or other injuries.
Steps you can take 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.
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.
Do not attempt to service, repair, or modify the airbag
supplemental restraint system (SRS) or its fuses. See your
authorized dealer.
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.

The airbags inflate and deflate
rapidly upon activation. After airbag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
airbag. Small amounts of sodium
hydroxide may be present which
may irritate the skin and eyes, but
none of the residue is toxic.
While the system is designed to help
reduce serious injuries, contact with
a deploying airbag may also cause abrasions, swelling or temporary
hearing loss. Because airbags must inflate rapidly and with considerable
force, there is the risk of death or serious injuries such as fractures,
facial and eye injuries or internal injuries, particularly to occupants who
are not properly restrained or are otherwise out of position at the time
of airbag deployment. Thus, it is extremely important that occupants be
properly restrained as far away from the airbag module as possible while
maintaining vehicle control.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the air bag has deployed,the air bag will not function
again and must be replaced immediately.If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
The SRS consists of:
•driver and passenger airbag modules (which include the inflators and
airbags)
•seat-mounted side airbags . Refer toSeat-mounted side airbag
systemlater in this chapter
•safety belt pretensioners
•one or more impact and safing sensors

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
back up power, the airbag ignitors and safety belt pretensioners.
Front passenger sensing system
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to disable (will not inflate) the front passenger’s frontal
airbag under certain conditions.
The front passenger sensing system works with sensors that are part of
the front passenger’s seat and safety belt. The sensors are designed to
detect the presence of a properly seated occupant and determine if the
front passenger’s frontal airbag should be enabled (may inflate) or
disabled (will not inflate).
The front passenger sensing system will disable (will not inflate) the
front passenger’s frontal airbag if:
•the front passenger seat is unoccupied, or has small/medium objects in
the front seat.
•the system determines that an infant is present in a rear-facing infant
seat that is installed according to the manufacturer’s instructions.
•the system determines that a small child is present in a forward-facing
child restraint that is installed according to the manufacturer’s
instructions.
•the system determines that a small child is present in a booster seat.
•a front passenger takes his/her weight off of the seat for a period of
time.

How does the Safety Canopy™ system work?
The design and development of the
Safety Canopy™ system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags (including the Safety
Canopy™).
The Safety Canopy™ system
consists of the following:
•An inflatable nylon curtain with a
gas generator concealed behind
the headliner and above the doors
(one on each side of vehicle).
•A headliner designed to flex open
above the side doors to allow
Safety Canopy™ deployment.
•The same readiness airbag light, electronic control and diagnostic unit
as used for the front airbags.
•Two crash sensors mounted on the B pillar (one on each side of the
vehicle).
•Two crash sensors located at the C pillar behind the rear doors (one
on each side of the vehicle).
•Rollover sensor in the restraints control module (RCM).
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 or third 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.

Hitches
Do not use hitches that clamp onto the vehicle’s bumper or attach to the
axle. You must distribute the load in your trailer so that 10%–15% of the
total weight of the trailer is on the tongue.
Safety chains
Always connect the trailer’s safety chains to the hook retainers on the
hitch. To connect the trailer’s safety chains, cross the chains under the
trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Be sure your trailer conforms to all applicable local and Federal
Regulations regarding trailer braking. If your trailer is equipped with
electronically controlled brakes you will need to have an electronic brake
controller with associated wiring installed to your vehicle by an
authorized dealer.
Do not connect a trailer’s hydraulic brake system directly to your
vehicle’s brake system. Your vehicle may not have enough
braking power and your chances of having a collision greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working.
Do not splice into the vehicle lamp wiring for trailer lamps. Your
vehicle uses an advanced electronic module to control and
monitor your vehicle lamps. Splicing into the wiring or attaching
wiring to the vehicle bulb. may DISABLE the rear vehicle lamps
or cause them not to function properly. Your lamp outage feature
may also be disabled or provide incorrect information.
See your authorized dealer or trailer rental agency for proper
instructions and equipment for hooking up trailer lamps.
