Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake
system or vacuum system of your vehicle
with that of the trailer. This could cause
inadequate braking and possible personal
injury.
An electronically actuated trailer brake
controller is required when towing a trailer
with electronically actuated brakes. When
towing a trailer equipped with a hydraulic
surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers
over 1,000 lbs (453 kg) and required for
trailers in excess of 2,000 lbs (907 kg).
Towing Requirements — Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the
trailer size, stoplights and turn signals on the
trailer are required for motoring safety.
The Trailer Tow Package may include a four-
and seven-pin wiring harness. Use a factory
approved trailer harness and connector.

NOTE:

Do not cut or splice wiring into the vehicle’s
wiring harness.
The electrical connections are all complete to
the vehicle but you must mate the harness to
a trailer connector. Refer to the following illus -
trations.

NOTE:

Disconnect trailer wiring connector from the
vehicle before launching a boat (or any
other device plugged into vehicle’s elec -
trical connect) into water.
Be sure to reconnect once clear from water
area. Four-Pin Connector
Seven-Pin Connector
WARNING!
Do not connect trailer brakes to your
vehicle's hydraulic brake lines. It can over -
load your brake system and cause it to
fail. You might not have brakes when you
need them and could have an accident.
Towing any trailer will increase your stop -
ping distance. When towing, you should
allow for additional space between your
vehicle and the vehicle in front of you.
Failure to do so could result in an acci -
dent.
CAUTION!
If the trailer weighs more than 1,000 lbs
(453 kg) loaded, it should have its own
brakes and they should be of adequate
capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake
pedal effort, and longer stopping distances.

Supplemental Restraint Systems (SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
The air bag system must be ready to protect
you in a collision. The Occupant Restraint
Controller (ORC) monitors the internal circuits
and interconnecting wiring associated with the
electrical Air Bag System Components. Your
vehicle may be equipped with the following Air
Bag System Components:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
Air Bag Warning Light
The Occupant Restraint Controller
(ORC) monitors the readiness of the
electronic parts of the air bag system
whenever the ignition switch is in the
START or ON/RUN position. If the ignition
switch is in the OFF position or in the ACC posi -
tion, the air bag system is not on and the air
bags will not inflate.
The ORC contains a backup power supply
system that may deploy the air bag system
even if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in
the instrument panel for approximately four to
eight seconds for a self-check when the igni -
tion switch is first in the ON/RUN position.
After the self-check, the Air Bag Warning Light
will turn off. If the ORC detects a malfunction
in any part of the system, it turns on the Air
Bag Warning Light, either momentarily or continuously. A single chime will sound to alert
you if the light comes on again after initial
startup.
The ORC also includes diagnostics that will illu
-
minate the instrument panel Air Bag Warning
Light if a malfunction is detected that could
affect the air bag system. The diagnostics also
record the nature of the malfunction. While
the air bag system is designed to be mainte -
nance free, if any of the following occurs, have
an authorized dealer service the air bag
system immediately.The Air Bag Warning Light does not come on
during the four to eight seconds when the
ignition switch is first in the ON/RUN posi -
tion.
The Air Bag Warning Light remains on after
the four to eight-second interval.
The Air Bag Warning Light comes on inter-
mittently or remains on while driving.

NOTE:

If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant
Restraint Controller (ORC) may also be
disabled. In this condition the air bags may not
be ready to inflate for your protection. Have an
authorized dealer service the air bag system
immediately.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the
seat belt or children who are using booster
seats. The locked mode is only used to
install rear-facing or forward-facing child
restraints that have a harness for
restraining the child.

compartment. The Side Air Bags may deploy
during angled or offset frontal collisions where
the front air bags deploy.
Side Air Bags are a supplement to the seat belt
restraint system. Side Air Bags deploy in less
time than it takes to blink your eyes.
NOTE:

Air bag covers may not be obvious in the inte-
rior trim, but they will open during air bag
deployment.
Rollover Events
Side Air Bags and seat belt pretensioners are
designed to activate in certain rollover events.
The Occupant Restraint Controller (ORC)
determines whether deployment in a partic -
ular rollover event is appropriate, based on the
severity and type of collision. Vehicle damage
by itself is not a good indicator of whether or
not Side Air Bags and seat belt pretensioners
should have deployed.
The Side Air Bags and seat belt pretensioners
will not deploy in all rollover events. The roll -
over sensing system determines if a rollover
event may be in progress and whether deploy -
ment is appropriate. In the event the vehicle
experiences a rollover or near rollover event, and deployment is appropriate, the rollover
sensing system will deploy the side air bags
and seat belt pretensioners on both sides of
the vehicle.
The SABICs may help reduce the risk of partial
or complete ejection of vehicle occupants
through side windows in certain rollover or
side impact events.

WARNING!
Occupants, including children, who are up
against or very close to Side Air Bags can
be seriously injured or killed. Occupants,
including children, should never lean on or
sleep against the door, side windows, or
area where the side air bags inflate, even
if they are in an infant or child restraint.

Seat belts (and child restraints where appro -
priate) are necessary for your protection in
all collisions. They also help keep you in
position, away from an inflating Side Air Bag.
To get the best protection from the Side Air
Bags, occupants must wear their seat belts
properly and sit upright with their backs
against the seats. Children must be properly
restrained in a child restraint or booster seat
that is appropriate for the size of the child.

WARNING!
Side Air Bags need room to inflate. Do not
lean against the door or window. Sit
upright in the center of the seat.
Being too close to the Side Air Bags during
deployment could cause you to be
severely injured or killed.
Relying on the Side Air Bags alone could
lead to more severe injuries in a collision.
The Side Air Bags work with your seat belt
to restrain you properly. In some colli -
sions, Side Air Bags won’t deploy at all.
Always wear your seat belt even though
you have Side Air Bags.

WARNING!
Modifications to any part of the air bag
system could cause it to fail when you
need it. You could be injured if the air bag
system is not there to protect you. Do not
modify the components or wiring,
including adding any kind of badges or
stickers to the steering wheel hub trim
cover or the upper passenger side of the
instrument panel. Do not modify the front
fascia/bumper, vehicle body structure, or
add aftermarket side steps or running
boards.
It is dangerous to try to repair any part of
the air bag system yourself. Be sure to tell
anyone who works on your vehicle that it
has an air bag system.
WARNING! (Continued)
Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function properly if
modifications are made. Take your vehicle
to an authorized dealer for any air bag
system service. If your seat, including your
trim cover and cushion, needs to be
serviced in any way (including removal or
loosening/tightening of seat attachment
bolts), take the vehicle to an authorized
dealer. Only manufacturer approved seat
accessories may be used. If it is necessary
to modify the air bag system for persons
with disabilities, contact an authorized
dealer.
