16GETTING TO KNOW YOUR VEHICLE
NOTE:
When having the Sentry Key Immobilizer system
serviced, bring all vehicle keys with you to an
authorized dealer.
Keys must be ordered to the correct key cut to
match the vehicle locks.
It is not mandatory to replace the key fob if a
new emergency key is needed, and vice versa.
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 will shut the engine off in two seconds
if an invalid key fob is used to start the engine.
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 used an invalid key fob to start the
engine. Either of these conditions will result in the
engine being 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
Ú
page 280.
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 switch with the push of a button as long as
the key fob is in the passenger compartment within
the area of the front driver and passenger seats.
The START/STOP ignition button has three
operating modes: 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
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.

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.
Vehicles equipped with the Anti-Lock Brake System
(ABS) are also equipped with Electronic Brake
Force Distribution (EBD). In the event of an EBD
failure, the Brake Warning Light will turn on along
with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the OFF
position to the ON/RUN position. The light should
illuminate for approximately two seconds. The light
should then turn off unless the parking brake is
applied or a brake fault is detected. If the light does
not illuminate, have the light inspected by an
authorized dealer. The light also will turn on when the parking brake
is applied with the ignition switch in the ON/RUN
position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake
application.
Battery Charge Warning Light

This warning light will illuminate when the
battery is not charging properly. If it stays on
while the engine is running, there may be
a malfunction with the charging system.
Contact an authorized dealer as soon as possible.

This indicates a possible problem with the
electrical system or a related component.
Door Open Warning Light

This indicator will illuminate when one or
more door(s) are not fully closed. A pop-up
appears on the instrument cluster display
showing which door is open.

NOTE:If the vehicle is moving and a door is opened, there
will also be a single chime.
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.

the vehicle is safely and completely stopped and the
transmission is placed in the PARK (P) position.
The light should turn off. If the light remains on with the
vehicle running, your vehicle will usually be drivable;
however, see an authorized dealer for service as soon
as possible.

If the light continues to flash when the vehicle is
running, immediate service is required and you may
experience reduced performance, an elevated/
rough idle, or engine stall and your vehicle may
require towing. The light will come on when the
ignition is placed in the ON/RUN or MAR/ON/RUN
position and remain on briefly as a bulb check. If the
light does not come on during starting, have the
system checked by an authorized dealer.

Engine Temperature Warning Light
This light warns of an overheated
engine condition. If the engine coolant
temperature is too high, this indicator will
illuminate and a single chime will sound.
