KEYS
Key Fob
Your vehicle uses a keyless ignition system.
The ignition system consists of a key fob with
Remote Keyless Entry (RKE) and a START/
STOP push button ignition system. The Re-
mote Keyless Entry system consists of a key
fob and Keyless Enter-N-Go feature if
equipped.
NOTE:
The key fob may not be found if it is located
next to a mobile phone, laptop or other elec-
tronic device; these devices may block the
key fob’s wireless signal.
The key fob allows you to lock or unlock the
doors and liftgate from distances up to ap-
proximately 66 ft (20 m) using a handheld
key fob. The key fob does not need to be
pointed at the vehicle to activate the system.
NOTE:
• In the ON/RUN position, the lock button is
disabled. Only the unlock button is en-
abled.• With ignition on/start and the vehicle mov-
ing at 5 mph, all RKE commands are
disabled.NOTE:
In case the ignition switch does not change
with the push of a button, the key fob may
have a low or dead battery. In this situation, a
back up method can be used to operate the
ignition switch. Put the nose side of the key
fob (side opposite of the Emergency Key)
against the ENGINE START/STOP button and
push to operate the ignition switch.

HEAD RESTRAINTS
Head restraints are designed to reduce the
risk of injury by restricting head movement in
the event of a rear impact. Head restraints
should be adjusted so that the top of the head
restraint is located above the top of your ear.
WARNING!
• All occupants, including the driver,
should not operate a vehicle or sit in a
vehicle’s seat until the head restraints
are placed in their proper positions in
order to minimize the risk of neck injury
in the event of a crash.
• Head restraints should never be ad-
justed while the vehicle is in motion.
Driving a vehicle with the head restraints
improperly adjusted or removed could
cause serious injury or death in the event
of a collision.
Front Adjustment
Active Head Restraints are passive, deploy-
able components, and vehicles with this
equipment cannot be readily identified by
any markings, only through visual inspection
of the head restraint. The Active Head Re-
straints (AHR) will be split in two halves, with
the front half being soft foam and trim, the
back half being decorative plastic.
When AHRs deploy during a rear impact, the
front half of the head restraint extends for-
ward to minimize the gap between the back of
the occupant’s head and the AHR. This sys-
tem is designed to help prevent or reduce the
extent of injuries to the driver and front pas-
senger in certain types of rear impacts. Refer
to “Occupant Restraint Systems” in “Safety”
in your Owner’s Manual for further informa-
tion.
