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.

TURN SIGNALS
Move the multifunction lever up or down to activate the
turn signals. The arrows on each side of the instrument
cluster display flash to show proper operation.
Once the turn signal lever is activated, it will return to its
original position. To cancel the turn signal action, the lever
must be moved again or the turn in that direction must be
completed.
NOTE:If either light remains on and does not flash, or there is a
very fast flash rate, check for a defective outside light
bulb.
LANE CHANGE ASSIST
Lightly push the multifunction lever up or down, without
moving beyond the detent, and the turn signal will flash
three times then automatically turn off.
To turn off the flashing before the end of the cycle, move
the lever in the opposite direction until the first click
(about half way).
BATTERY SAVER FEATURE
To protect the battery, if the headlight switch is left in the
low beam or parking lights position when the ignition is
placed in the OFF position, the lights are deactivated after
eight minutes. The lights can also be turned off manually
by rotating the headlight switch to the O (off) position.
INTERIOR LIGHTS
INTERIOR COURTESY LIGHTS
Courtesy and dome lights are turned on when the front
doors are opened.
To protect the battery, the interior lights will turn off
automatically 15 minutes after the ignition is placed in the
OFF position, and no other activity in the vehicle has
occurred. This will occur if the interior lights were turned
on manually or are on because a door is open. This
includes the glove compartment light and the cargo area
light. To restore interior light operation, either place the
ignition in the ON/RUN position, or push the light switch on
and then back off.
Front Map Reading Lights
The front map/reading and overhead lights are mounted
in the overhead console. Each light can be turned on by
pushing the corresponding switch on the console. These
switches are backlit for nighttime visibility. To turn the
lights off, push the switch a second time.

Overhead Console

NOTE:
Before exiting the vehicle, ensure that the overhead lights
are off. This will prevent the battery from discharging once
the doors are closed. If a light is left on accidentally, the
overhead lights will turn off automatically approximately
15 minutes after the ignition has been placed in the
OFF position. 1 — Reading/Map Light Switch

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.
