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 ignition keys which have an
embedded electronic chip (transponder) to
prevent unauthorized vehicle operation.
Therefore, only keys that are programmed to
the vehicle can be used to start and operate the
vehicle.
If the vehicle security light is on after the key is
placed in the MAR (ACC/ON/RUN) position, it
indicates that there is a problem with the
electronics.
All of the keys provided with your new vehicle
have been programmed to the vehicle
electronics.NOTE:
A key which has not been programmed is also
considered an invalid key, even if it is cut to fit
the ignition switch lock cylinder for that vehicle
Ú
page 265.
IGNITION SWITCH

1. Place the gear selector in PARK.

2. Rotate the key to the STOP (OFF/LOCK)
position.
3. Remove the key from the ignition switch lock cylinder.

Ignition Switch Positions

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.
1 — STOP (OFF/LOCK)
2 — MAR (ACC/ON/RUN)
3 — AVV (START)
WARNING!
Before exiting a vehicle, always shift the
transmission into PARK, apply the parking
brake, and remove the key fob from the
vehicle. When leaving the vehicle, always
lock your vehicle. In case you switch off the
vehicle and the transmission is not in
PARK, a warning message will appear on
the cluster which suggests you to shift the
transmission into PARK and, then, you can
remove the key within 15 seconds. If
15 seconds expire, you have to rotate the
key from the OFF/LOCK position to the ON/
RUN position and come back to the OFF/
LOCK position in order to remove the key.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended 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.

21_VM_OM_EN_USC_t.book Page 12

GETTING TO KNOW YOUR VEHICLE13
NOTE:
When opening the driver’s door with the key in
the ignition and the ignition placed in the STOP
(OFF/LOCK) position, a chime will sound to
remind you to remove the key.
VEHICLE SECURITY SYSTEM — IF EQUIPPED
The Vehicle Security system monitors the
vehicle doors and ignition for unauthorized
operation. When the Vehicle Security system is
activated, interior switches for door locks are
disabled. The system provides both audible and
visible signals. Every intrusion attempt causes
six continuous alarm cycles. Every alarm cycle
lasts for 30 seconds. For 26 seconds, the horn
will sound, and the turn signal lights will flash.
For four seconds, it will pause. After a maximum
of 10 alarm cycles, only the turn signal lights will
flash until the next alarm activation.
To Arm The System
The Vehicle Security system will arm when you
use the key fob to lock the doors. If a door or the
hood is not properly shut, the alarm system will
not be armed.
To Disarm The System
Use the key fob to unlock the door and disarm
the system. The Vehicle Security system will also disarm if a
programmed Sentry Key is inserted into the
ignition switch. To exit the alarm mode, push
the key fob unlock button, or insert a
programmed Sentry Key into the ignition switch.
The Vehicle Security system 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 described arming
sequences has occurred, the Vehicle Security
system 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 Security system.
Rearming Of The System
If the system has not been disabled, the Vehicle
Security system will rearm itself after the
15 additional minutes of turn lamps flashing. If
the condition which initiated the alarm is still
present, the system will ignore that condition
and monitor the remaining doors and ignition.
Security System Manual Override
The Vehicle Security system will not arm if you
lock the doors using the manual door lock.
Do not leave the key fob in or near the
vehicle, or in a location accessible to chil-
dren. 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. Always
remove the key from the ignition and lock all
the doors when leaving the vehicle
unattended.
