ELECTRICAL POWER OUTLETS
Your vehicle is equipped with 12 Volt (13 Amp)
power outlets that can be used to power cellular
phones, small electronics and other low powered
electrical accessories. The power outlets are
labeled with either a key or a battery symbol to
indicate how the outlet is powered. Power outlets
labeled with a key symbol are powered when the
ignition switch is in the ON or ACC position, while
the outlets labeled with a battery symbol are
connected directly to the battery, and are powered
at all times.
NOTE:
All accessories connected to the battery
powered outlets should be removed or turned
off when the vehicle is not in use to protect the
battery against discharge.
Do not exceed the maximum power of 160
Watts (13 Amps) at 12 Volts. If the 160 Watt
(13 Amp) power rating is exceeded the fuse
protecting the system needs to be replaced.
Power outlets are designed for accessory plugs
only. Do not insert any other object in the power
outlets as this will damage the outlet and blow
the fuse. Improper use of the power outlet can
cause damage not covered by your New Vehicle
Limited Warranty.
The front power outlet is located to the right of the
climate controls.

After an accident, if the vehicle will not start after
performing the reset procedure, the vehicle must
be towed to an authorized dealer to be inspected
and to have the Enhanced Accident Response
System reset.
Maintaining Your Air Bag System Event Data Recorder (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is to

situations, such as an air bag deployment or hitting
a road obstacle, data that will assist in
understanding how a vehicle’s systems performed.
The EDR is designed to record data related to
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 compo-
nents 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.
Do not attempt to modify any part of your air
bag system. The air bag may inflate acciden -
tally or may not function properly if modifica -
tions 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 autho -
rized dealer.
