16GETTING TO KNOW YOUR VEHICLE
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 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
Úpage 275.
NOTE:A key fob that has not been programmed is also
considered an invalid key.
IGNITION SWITCH
KEYLESS ENTER ‘N GO™ IGNITION
This feature allows the driver to operate the ignition with
the push of a button as long as the key fob is in the
passenger compartment.
The START/STOP ignition button has three operating
modes. The three modes are: OFF, ON/RUN, and START.

START/STOP Ignition Button

The push button ignition can be placed in the following
modes:
OFF

The engine is stopped.
 Some electrical devices (e.g., power locks, alarm, etc.)
are still available.
ON/RUN
 Driving mode.
 All electrical devices are available (e.g., climate
controls, heated seats, etc.).
START
 The engine will start.
CAUTION!
The Sentry Key Immobilizer system is not compatible
with some aftermarket Remote Start systems. Use of
these systems may result in vehicle starting problems
and loss of security protection.

REMOTE START ABORT MESSAGE —
I
F EQUIPPED
One of the following messages will display in the
instrument cluster display if the vehicle fails to remote
start or exits Remote Start prematurely:
 Remote Start Aborted — Door Open
 Remote Start Aborted — Hood Open
 Remote Start Aborted — Fuel Low
 Remote Start Aborted — Liftgate Open
 Remote Start Aborted — Too Cold
 Remote Start Aborted — Time Expired
 Remote Start Disabled — Start Vehicle To Reset
The message will stay active until the ignition is placed in
the ON/RUN position.
VEHICLE SECURITY SYSTEM — IF EQUIPPED
The Vehicle Security system monitors the vehicle doors,
hood, liftgate, and the Keyless Enter ‘n Go™ Ignition for
unauthorized operation. It also monitors movement inside
the passenger compartment (volumetric protection —
if equipped), cutting of battery cables, and unexpected
lifting/tilting of the vehicle (anti-lift protection —
if equipped). If something triggers the system, the Vehicle Security
system will provide the following audible and visible
signals:

The horn will pulse
 The turn signals will flash
NOTE:
The Vehicle Security system is activated by the Engine
Immobilizer system, which is automatically activated
when you get out of the vehicle with the key fob and
lock the doors.
 The Vehicle Security system is factory adjusted to stan -
dards from different countries.
 The Vehicle Security system is a complementary secu -
rity system developed to hinder the occurrence of
vehicle theft and prevent vandalism. It does not
prevent the theft of your vehicle; the system is a deter -
rent.
TO ARM THE SYSTEM
Follow these steps to arm the Vehicle Security system:

1. Make sure the vehicle’s ignition is placed in the OFF position.

 For vehicles equipped with Keyless Entry, make
sure the vehicle’s keyless ignition system is OFF. 2. Perform one of the following methods to lock the
vehicle:
 Push the lock button on the interior power door
lock switch with 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
Úpage 23.
 Push the lock button on the key fob.
3. If any doors (or liftgate) are open, close them.
When the Vehicle Security system is armed (except on
some versions for specific markets), the system will emit
an acoustic warning and a warning light (located next to
the interior door handle) will flash until it is disarmed.
NOTE:
 If there is a fault with the system, the system will emit
an acoustic signal a second time.
 If this occurs, wait about 4 seconds and switch off the
Vehicle Security system following this procedure:
a. Press the unlock button on the key fob.
b. Check that the doors, hood, and liftgate are closed, and then reactivate the system by pressing
the lock button.
 If the alarm emits a sound even when the doors, hood,
and liftgate are closed, there is a fault with the system.
Contact an authorized dealer for assistance.
 The vehicle doors can be locked without arming the
Vehicle Security system by using the emergency key in
the exterior door lock cylinder.

The battery was recently replaced and was not charged
completely.
 The battery was discharged by an electrical load left on
when the vehicle was parked.
 The battery was used for an extended period with the
engine not running to supply radio, lights, chargers,
+12 Volts portable appliances like vacuum cleaners,
game consoles and similar devices.
What to do when an electrical load reduction action
message is present (“Battery Saver On” or
“Battery Saver Mode”)
During a trip:
 Reduce power to unnecessary loads if possible:
 Turn off redundant lights (interior or exterior)
 Check what may be plugged into power outlets
+12 Volts, 150W, USB ports
 Check HVAC settings (blower, temperature)
 Check the audio settings (volume)
After a trip:
 Check if any aftermarket equipment was installed
(additional lights, upfitter electrical accessories,
audio systems, alarms) and review specifications if any
(load and Ignition Off Draw currents).
 Evaluate the latest driving cycles (distance, driving
time and parking time).
 The vehicle should have service performed if the
message is still present during consecutive trips and
the evaluation of the vehicle and driving pattern did not
help to identify the cause.WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the
instrument panel together with a dedicated message and/
or acoustic signal when applicable. These indications are
indicative and precautionary and as such must not be
considered as exhaustive and/or alternative to the
information contained in the Owner’s Manual, which you
are advised to read carefully in all cases. Always refer to
the information in this chapter in the event of a failure
indication. All active telltales will display first if applicable.
The system check menu may appear different based upon
equipment options and current vehicle status. Some
telltales are optional and may not appear.
RED WARNING LIGHTS
Air Bag Warning Light
This warning light will illuminate to indicate a
fault with the air bag, and will turn on for four to
eight seconds as a bulb check when the
ignition is placed in the ON/RUN position. This
light will illuminate with a single chime when a fault with
the air bag has been detected, it will stay on until the fault
is cleared. If the light is either not on during startup, stays
on, or turns on while driving, have the system inspected at
an authorized dealer as soon as possible.
Brake Warning Light
This warning light monitors various brake
functions, including brake fluid level and
parking brake application. If the brake light
turns on it may indicate that the parking brake
is applied, that the brake fluid level is low, or that there is
a problem with the Anti-Lock Brake System reservoir. If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition has
been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake,
and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity
in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp cornering
maneuvers, which change fluid level conditions. The
vehicle should have service performed, and the brake
fluid level checked.
If brake failure is indicated, immediate repair is necessary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately.
