KEYS
Key Fob
Key FobYour vehicle uses a keyless ignition system.
The ignition system consists of a key fob with
Keyless Go and a START/STOP push button
ignition system. The Remote Keyless Entry
(RKE) system consists of a key fob with a
mechanical key and Keyless Enter-N-Go
feature (if equipped).
NOTE:
The key fob may not be detected by the
vehicle if it is located next to a mobile phone,
laptop or other electronic device; these
devices may block the key fob’s wireless
signal.
The key fob allows you to lock or unlock the
doors and swing gate from distances up to
approximately 66 ft (20 m). The key fob
does not need to be pointed at the vehicle to
activate the system. NOTE:
With the ignition in the ON/RUN position
and with the vehicle doors open, the lock
button will be disabled, and only the unlock
button will be enabled. All RKE commands
will be disabled once the vehicle begins
moving at 2 mph (4 km/h) or above.
Backup Mode Starting
In case the ignition switch does not change
with the push of a button, the key fob may
have a low or fully depleted battery. A low key
fob battery can be verified by referring to the
instrument cluster, which will display direc
-
tions to follow.
NOTE:
A low key fob battery condition may be indi -
cated by a message in the instrument cluster
display, or by the LED light on the key fob. If
the LED key fob light no longer illuminates
from key fob button pushes, then the key fob
battery requires replacement.
