2010 JEEP GRAND CHEROKEE wiring

WARNING!
Deployed airbags and seat belt pretensioners cannot
protect you in another collision. Have the airbags,
seat belt pretensioners, and the front passenger seat
belt retractor assembly replaced by an authorized
dealer as soon as possible. Also, have the Occupant
Restraint Controller (ORC) system serviced as well.
Maintaining Your Airbag System
WARNING!
•Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured if the airbag 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 right side of the instrument panel. Do not
modify the front bumper, vehicle body structure,
or add aftermarket side steps or running boards.
•It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has an airbag system.(Continued)

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 57

CAUTION!
If the trailer weighs more than 1,000 lbs (454 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.
WARNING!
•Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have an
accident.(Continued)
WARNING! (Continued)
•Towing any trailer will increase your stopping
distance. When towing, you should allow for ad-
ditional space between your vehicle and the ve-
hicle in front of you. Failure to do so could result
in an accident.
Towing Requirements – Trailer Lights and Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package includes a seven–pin connector
at the rear of the vehicle and a four-pin harness located
under the rear bumper. The four-pin harness must be
unclipped before use. Use a factory-approved trailer
harness and connector.5
