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 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 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 addi-
tion, if the light begins to flash after the bulb check, it indi -
cates 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 elec -
tronics, 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
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.
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.

VEHICLE SECURITY ALARM
The vehicle security alarm monitors the vehicle doors, tail-
gate, and ignition for unauthorized operation. When the
vehicle security alarm is activated, interior switches for door
locks are disabled. The system will turn the horn off after 29
seconds, 5 seconds between cycles, up to 8 cycles if the
trigger remains active and then the vehicle security alarm
will rearm itself.
To Arm The System
Follow these steps to arm the vehicle security alarm:
1. Remove the key from the ignition system (refer to "Starting The Engine" in "Starting And Operating" for
further information).
•Make sure the vehicle ignition system is "OFF."
2. Perform one of the following methods to lock the vehicle:
•Push lock button on the interior power door lock switchwith the driver and/or passenger door open.

• Push the lock button on the exterior Passive Entry Door Handle with a valid key fob available in the same exterior
zone (refer to "Keyless Enter- N-Go — Passive Entry" in
"Getting To Know Your Vehicle" for further information).

• Push the lock button on the key fob. 3. If any doors are open, close them.
The vehicle security alarm will set when you use the power
door locks, or use the key fob to lock the doors. After all the
doors are locked and closed, the vehicle security light, in the
instrument panel cluster, will flash rapidly for about 16
seconds to indicate that the alarm is being set. After the
alarm is set, the vehicle security light will flash at a slower
rate to indicate that the system is armed.
To Disarm The System
The vehicle security alarm can be disarmed using any of the
following methods:
1. Push the unlock button on the key fob.
2. Grasp the Passive Entry Unlock Door Handle with a valid
key fob within 5 ft (1.5 m) of the passive entry door
handle. If equipped, refer to "Keyless Enter-N-Go —
Passive Entry" in "Getting To Know Your Vehicle" for
further information.
3. Place the ignition out of the “OFF” position.
The vehicle security alarm is designed to protect your
vehicle. However, you can create conditions where the
system will give you a false alarm. If one of the previously

GETTING TO KNOW YOUR VEHICLE 33
described arming sequences has occurred, the vehicle secu-
rity alarm will arm regardless of whether you are in the
vehicle or not. If you remain in the vehicle and open a door,
the alarm will sound. If this occurs, disarm the vehicle secu-
rity alarm.
If the vehicle security alarm is armed and the battery
becomes disconnected, the vehicle security alarm will
remain armed when the battery is reconnected; the exterior
lights will flash, and the horn will sound. If this occurs,
disarm the vehicle security alarm.
Rearming Of The System
If something triggers the alarm, and no action is taken to
disarm it, the vehicle security alarm will turn the horn off
after 29 seconds, 5 seconds between cycles, up to 8 cycles if
the trigger remains active and then the vehicle security alarm
will rearm itself.
Security System Manual Override
The vehicle security alarm will not arm/disarm if you lock/
unlock the doors using the manual door lock plunger.

Keyless Enter-N-Go — Passive Entry
The Passive Entry system is an enhancement to the vehicle’s
Remote Keyless Entry system and a feature of Keyless
Enter-N-Go. This feature allows you to lock and unlock the
vehicle’s door(s) without having to push the key fob lock or
unlock buttons.
NOTE:

• Passive Entry may be programmed ON/OFF. Refer to “Ucon-
nect Settings” in “Multimedia” for further information.
• If wearing gloves on your hands, or if it has been raining/ snowing on the Passive Entry door handle, the unlock sensi -
tivity can be affected, resulting in a slower response time.

• If the vehicle is unlocked by Passive Entry and no door is opened within 60 seconds, the vehicle will re-lock and if
equipped will arm the security alarm.
• The vehicles security alarm can be armed/disarmed by pushing the passive entry key fob lock/unlock buttons (if
equipped).

laptop or other electronic device; these devices may block
the key fob's wireless signal and prevent the passive entry
handle from locking/unlocking the vehicle. To Unlock From The Driver's Side:
With a valid Passive Entry key fob within 5 ft (1.5 m) of the
driver door handle, grab the front driver door handle to
unlock the driver's door automatically. The interior door

Opening Sunroof
Express
Push the switch rearward and release it within one-half
second. The sunroof and sunshade will open automatically
and stop when the full open position is reached. This is called
“Express Open.” During Express Open operation, any other
actuation of the sunroof switch will stop the sunroof.
Manual Mode
To open the sunroof, push and hold the switch rearward. The
sunroof will move rearward and automatically stop at full
open position. Any release of the switch will stop the move-
ment. The sunroof and sunshade will remain in a partially
opened condition until the sunroof switch is pushed again.WARNING!
• Never leave children unattended in a vehicle, or with access to an unlocked vehicle. Never leave the key fob
in or near the vehicle, or in a location accessible to chil -
dren. Do not leave the ignition of a vehicle equipped
with Keyless Enter-N-Go in the ACC or ON/RUN
mode. Occupants, particularly unattended children,
can become entrapped by the power sunroof while
operating the power sunroof switch. Such entrapment
may result in serious injury or death.
• In a collision, there is a greater risk of being thrown from a vehicle with an open sunroof. You could also be
seriously injured or killed. Always fasten your seat belt
properly and make sure all passengers are also properly
secured.

Wind Buffeting
Wind buffeting can be described as the perception of pres -
sure on the ears or a helicopter-type sound in the ears. Your
vehicle may exhibit wind buffeting with the windows down,
or the sunroof (if equipped) in certain open or partially open
positions. This is a normal occurrence and can be minimized.
If the buffeting occurs with the rear windows open, then
open the front and rear windows together to minimize the buffeting. If the buffeting occurs with the sunroof open,
adjust the sunroof opening to minimize the buffeting or open
any window.
Sunshade Operation
The sunshade can be opened manually. However, the
sunshade will open automatically as the sunroof opens.
NOTE:
The sunshade cannot be closed if the sunroof is open.
Pinch Protect Feature
This feature will detect an obstruction in the closing of the
sunroof during the Express Close operation. If an obstruction
in the path of the sunroof is detected, the sunroof will auto
-
matically retract. Remove the obstruction if this occurs.
NOTE:
If three consecutive sunroof close attempts result in Pinch
Protect reversals, Pinch Protect will disable and the sunroof
must be closed in Manual Mode.
