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.
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
Ú
page 412.
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 Remote Keyless Entry key fob is in the
passenger compartment.
The Keyless Push Button Ignition has four
operating positions; three of which are labeled and will illuminate when in position. The three positions
are OFF, ACC, and ON/RUN. The fourth position is
START. During START, RUN will illuminate.
NOTE:In case the ignition switch does not change with
the push of a button, the key fob may have a low or
depleted battery. In this situation, a back up
method can be used to operate the ignition switch.
Put the nose side (side opposite of the emergency
key) of the key fob against the START/STOP
ignition button, with your foot applied on the brake
pedal, and push to operate the ignition switch.

Keyless Push Button Ignition

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.

Window Fogging
Vehicle windows tend to fog on the inside in mild,
rainy, and/or humid weather. To clear the
windows, select Defrost or Mix mode and increase
the front blower speed. Do not use the
Recirculation mode without A/C for long periods,
as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of
the windshield, is free of obstructions, such as
leaves. Leaves collected in the air intake may
reduce airflow, and if they enter the plenum, they
could plug the water drains. In Winter months,
make sure the air intake is clear of ice, slush, and
snow.
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized dealer to
service your cabin air filter, and to have it replaced
when needed.
