breathing exhaust, do not idle the engine except as necessary, service your vehicle in a well-ventilated area and
wear gloves or wash your hands frequently when servicing your vehicle. For more information go to

while driving. It is always the driver’s responsibility to comply with all local laws.

in the text. Therefore, you should only consider the information which is related to the trim level, engine, and version that you have purchased. Any
content introduced throughout the Owner’s Information, that may or may not be applicable to your vehicle, will be identified with the wording “If

Key Fob Battery Replacement

3. Remove the battery by turning the back cover over (battery facing downward) and
tapping it lightly on a solid surface such as
a table or similar surface, and then replace
the battery. When replacing the battery,
match the (+) sign on the battery to the (+)
sign on the inside of the battery clip, located
on the back cover. Avoid touching the new
battery with your fingers because skin oils
may cause battery deterioration. If you
touch a battery, clean it with rubbing
alcohol.
4. To assemble the key fob case, snap the two halves together.
Programming Additional Key Fobs
Programming the key fob may be performed by
an authorized dealer.
NOTE:
Once a key fob is programmed to a vehicle, it
cannot be repurposed and reprogrammed to
another vehicle.
Request For Additional Remote Controls
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. 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.
NOTE:
When having the Sentry Key Immobilizer system
serviced, bring all vehicle keys with you to an
authorized dealer.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 Innovation, Science and
Economic Development 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, including interference that may
cause undesired operation.
WARNING!

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.
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 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.
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.
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.
For vehicles equipped with Keyless
Enter-N-Go — Ignition, always remember to
place the ignition in the OFF position.
