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.
To Unlock The Doors And Liftgate
Push and release the unlock button on the
key fob once to unlock the driver's door or
twice within five seconds to unlock all doors
and the liftgate.
All doors can be programmed to unlock on the
first push of the unlock button. Refer to
“Uconnect Settings” in “Multimedia” in the
Owner’s Manual for further information.

NOTE:
If 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 igni-
tion switch. Put the nose side (side opposite
of the emergency key) of the key fob against
the ENGINE START/STOP button and push to
operate the ignition switch.
The push button ignition can be placed in the
following modes:OFF

ing, alarm, etc.) are still available.

WARNING!
• When exiting the vehicle, always remove
the key fob from the vehicle and lock
your vehicle.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.

attended is dangerous for a number of
reasons. A child or others could be seri-
WARNING!
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the gear selector.
• Do not leave the key fob in or near the
vehicle, or in a location accessible to
children, and do not leave the ignition of
a vehicle equipped with Keyless Enter-
N-Go in the ON/RUN mode. A child
could operate power windows, other con-
trols, or move the vehicle.
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury
or death.
CAUTION!
An unlocked vehicle is an invitation for
thieves. Always remove key fob from the
vehicle and lock all doors when leaving the
vehicle unattended.

And Operating" for further information.

stickers to the steering wheel hub trim
cover or the upper right side of the in-
strument panel. Do not modify the front

erly if modifications are made. Take your
