WARNING!
•When leaving 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.
• 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.
• 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 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 car is an invitation. Always remove the
key fobs from the vehicle and lock all doors when
leaving the vehicle unattended. NOTE:
For further information, refer to Starting The
Engine inStarting And Operating.
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
80° F (26.7° C), and the optional heated seats, and optional
heated steering wheel in temperatures below 40° F (4.4° C).
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.
How To Use Remote Start
•Push Remote Start button on the key fob twice within
five seconds. Pushing the Remote Start button a third
time shuts the engine off.
28 GETTING TO KNOW YOUR VEHICLE

•To drive the vehicle, push unlock button, and place the
ignition in the ON/RUN position.
• With remote start, the engine will only run for 15
minutes (timeout) unless the ignition key is placed in the
ON/RUN position.
• The vehicle must be started with the key after two
consecutive timeouts.
All of the following conditions must be met before the
engine will remote start:
• Gear Selector in PARK
• Doors closed
• Hood closed

• Fuel level meets minimum requirementWARNING!
•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 serious injury
or death when inhaled.
• Keep key fobs away from children. Operation of the
Remote Start System, windows, door locks or other
controls could cause serious injury or death.

To Enter Remote Start Mode
Push and release the Remote Start button on the key fob
twice within five seconds. The vehicle doors will lock, the
turn signals will flash twice, and the horn will chirp twice.
Then the engine will start, and the vehicle will remain in
the Remote Start mode for a 15-minute cycle.
NOTE:
•If an engine fault is present or fuel level is low, the
vehicle will start and then shut down in 10 seconds.
• The park lamps will turn on and remain on during
Remote Start mode.
• For security, power window operation is disabled when
the vehicle is in the Remote Start mode.
• The engine can be started two consecutive times (two
15-minute cycles) with the key fob. However, the igni-
tion must be placed in the ON/RUN position before you
can repeat the start sequence for a third cycle.
To Exit Remote Start Mode Without Driving The
Vehicle
Push and release the Remote Start button one time or allow
the remote start cycle to complete the entire 15-minute
cycle.

Remote Start Comfort Systems — If Equipped
When Remote Start is activated, the Climate Control,
vented seats (if equipped) are also activated in tempera-
tures above 80° F (26.7° C), and the optional heated seats,
and optional heated steering wheel in temperatures below
40° F (4.4° C). These features will stay on through the
duration of Remote Start or until the ignition switch is
cycled to the ON/RUN position.
General Information
The following regulatory statement applies to all radio
frequency (RF) devices equipped in this vehicle:
This device complies with Part 15 of the FCC Rules and
with Industry Canada license-exempt RSS standard(s).
Operation is subject to the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, in-cluding interference that may cause undesired opera-
tion.
NOTE: Changes or modifications not expressly approved
by the party responsible for compliance could void the
user ’s authority to operate the equipment.
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 cannot reprogram a key fob obtained from another
vehicle.
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 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 ten seconds), it
indicates that there is a fault in the electronics. Should this
3
GETTING TO KNOW YOUR VEHICLE 31

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 your autho-
rized 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.
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.
