WARNING!
• Before exiting a vehicle, always shift the automatic
transmission into PARK, apply the parking brake,
place the engine in the OFF position, remove the key
fob from the vehicle and lock your vehicle. If

• Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
• Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or others
could be seriously or fatally injured. Children
should be warned not to touch the parking brake,
brake pedal or the gear selector.

WARNING! (Continued)
•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 controls, 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. Al-
ways remove key fob from the vehicle and lock all
doors when leaving the vehicle unattended.
REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the key fob to start the engine
conveniently from outside the vehicle while still
maintaining security. The system has a range of
328 ft (100 m).
The Remote Starting System also activates the Climate
Control, vented seats (if equipped) in temperatures above

GETTING TO KNOW YOUR VEHICLE 27

80° F (26.7° C), and the optional heated seats, and optional
heated steering wheel in temperatures below 40° F (4.4° C).
Refer to “Front Heated Seats” and “Front Ventilated Seats”
in “Seats” for further information.
NOTE:
•The vehicle must be equipped with an automatic trans-
mission to be equipped with Remote Start.
• Obstructions between the vehicle and key fob may
reduce this range.
WARNING!
• Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Monox-
ide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause you or others
to be severely injured or killed when inhaled.

Remote Start System, windows, door locks or other
controls could cause you and others to be severely
injured or killed.

unlock button on the key fob to unlock the doors, or unlock
the vehicle using Keyless Enter-N-Go — Passive Entry via
the door handles, and disarm the Vehicle Security Alarm (if
equipped). Then, prior to the end of the 15-minute cycle,
push and release the START/STOP button.
NOTE: For vehicles equipped with the Keyless Enter-

When Remote Start is activated, Auto-Comfort will work
anytime the temperature conditions are correct. When the
feature is enabled, regardless of Remote Start or regular
keyless start, the driver heated seat features will automati-

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 is
placed in the ON/RUN position.

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 RF receiver to prevent unauthorized vehicle opera-
tion. Therefore, only key fobs that are programmed to the
vehicle can be used to start and operate the vehicle. The
system will not allow the engine to crank if an invalid key
fob is used to start and operate the vehicle. The system will
shut the engine off in two seconds if an invalid key fob is
used to start the engine.
After turning the ignition switch to 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 used an invalid key fob to start the
engine. Either of these conditions will result in the engine
being 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.
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.
All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Customer 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!
• Always remove the key fobs from the vehicle and
lock all doors when leaving the vehicle unattended.
• For vehicles equipped with Keyless Enter-N-Go —
Ignition, always remember to place the ignition in
the OFF position.
NOTE: Duplication of key fobs may be performed at an
authorized dealer. This procedure consists of programming
a blank key fob to the vehicle electronics. A blank key fob
is one that has never been programmed.
When having the Sentry Key Immobilizer System serviced,
bring all vehicle keys with you to an authorized dealer.
