Remote Start Comfort Systems — If
Equipped
When remote start is activated, the heated
steering wheel, and driver heated seat features
will automatically turn on in cold weather. In
warm weather, the driver vented seat feature
will automatically turn on when the remote start
is activated. These features will stay on through
the duration of remote start or until the ignition
switch is placed in the ON/RUN position.
NOTE:
The Remote Start Comfort system can be acti-
vated and deactivated through the Uconnect
System under “Auto-On Comfort And Remote
Start”. Refer to “Uconnect Settings” in “Multi -
media” for further information on Remote Start
Comfort System operation.
SENTRY KEY
The Sentry Key Immobilizer system prevents
unauthorized vehicle operation by disabling the
engine. The system does not need to be armed
or activated. Operation is automatic, regardless
of whether the vehicle is locked or unlocked.
The system uses a key fob, keyless push button
ignition and a Radio Frequency (RF) receiver to
prevent unauthorized vehicle operation. There -fore, only key fobs that are programmed to the
vehicle can be used to start and operate the
vehicle. The system cannot reprogram a key fob
obtained from another vehicle.
After placing the ignition switch in the ON/RUN
position, the vehicle security light will turn on for
three seconds for a bulb check. If the light
remains on after the bulb check, it indicates
that there is a problem with the electronics. In
addition, if the light begins to flash after the
bulb check, it indicates that someone
attempted to start the engine with an invalid key
fob. In the event that a valid key fob is used to
start the engine but there is an issue with the
vehicle electronics, the engine will start and
shut off after two seconds.
If the vehicle security light turns on during
normal vehicle operation (vehicle running for
longer than 10 seconds), it indicates that there
is a fault in the electronics. Should this occur,
have the vehicle serviced as soon as possible by
an authorized dealer.
All of the key fobs provided with your new
vehicle have been programmed to the vehicle
electronics.
Key Programming
Programming key fobs may be performed at an
authorized dealer.
Replacement Keys
NOTE:

Only key fobs that are programmed to the vehicle
electronics can be used to start and operate the
vehicle. Once a key fob is programmed to a vehicle,
it cannot be programmed to any other vehicle.

CAUTION!

The Sentry Key Immobilizer system is not
compatible with some aftermarket remote
starting systems. Use of these systems may
result in vehicle starting problems and loss of
security protection.

CAUTION!
Always remove the key fobs from the
vehicle and lock all doors when leaving the
vehicle unattended.

position.
If one of the vehicle doors is open and the door
panel switch is used to lock the vehicle, once all
open doors have been closed the vehicle
checks the inside and outside of the vehicle for
any valid Passive Entry key fobs. If one of the
vehicle's Passive Entry key fobs is detected inside the vehicle, and no other valid Passive
Entry key fobs are detected outside the vehicle,
the Passive Entry System automatically unlocks
all vehicle doors and chirps the horn three times
(on the third attempt ALL doors will lock and the
Passive Entry key fob can be locked in the
vehicle).
To Lock The Vehicle’s Doors:
With one of the vehicle’s Passive Entry key fobs
within 5 ft (1.5 m) of the driver or passenger
