Programming And Requesting Additional
Key Fobs

another vehicle. Duplication of keys may be performed at an
authorized dealer. The VIN is required for

NOTE:
Only keys that have been programmed to the
vehicle electronics can be used to start the
vehicle. Once a Sentry Key has been
programmed to a vehicle, it cannot be
programmed to any other vehicle. When having
the Sentry Key Immobilizer system serviced,
bring all vehicle keys with you to an authorized
dealer.
WARNING!
Always remove the key fobs from the
vehicle and lock all doors when leaving the

FOLLOW ME HOME/HEADLIGHT DELAY
When this feature is selected, the driver can
choose to have the headlights remain on for a
preset period of time after the engine is turned
off.
Activation
Remove the key or turn the ignition to the STOP
(OFF/LOCK) position, and pull the multifunction
lever toward the steering wheel within two
minutes. Each time the lever is pulled, the
activation of the lights will be extended by
30 seconds. The activation of the lights can be
extended to a maximum of 210 seconds.
The indicator light on the instrument panel will
light up and the corresponding message will
appear in the instrument cluster display for as
long as the function is activated. The indicator
light comes on when the lever is operated and
stays on until the function is automatically
deactivated. Each movement of the lever only
increases the amount of time the lights stay on.
Deactivation
Pull the multifunction lever toward the steering
wheel and hold it for more than two seconds.
FOG LIGHTS — IF EQUIPPED
The fog light switch is located on the center
stack of the instrument panel, just below the
climate controls.
Push the switch once to turn the fog
lights on. Push the switch a second
time to turn the fog lights off.
NOTE:
If the vehicle’s ignition is turned off, the fog
lights will also turn off.
TURN SIGNALS
Move the multifunction lever up or down and
the arrows on each side of the instrument
cluster will flash to show proper operation of the
turn signals.
NOTE:
If either light remains on and does not flash, or
there is a very fast flash rate, check for a defec -
tive 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 five times then automatically
turn off.
BATTERY SAVER
To protect the life of your vehicle’s battery,
when the ignition is OFF and any door is left ajar
for 15 minutes, the interior lights will
automatically turn off.
NOTE:

placed in the MAR (ACC/ON/RUN) position.

SAFETY179
(Continued)
Fuel Cut Off Switch
Your vehicle is equipped with a Fuel Cut Off
switch. In the event of an accident, if the
communication network remains intact, and
the power remains intact, depending on the
nature of the event, the Fuel Cut Off Switch may
perform the following functions:
Cut off fuel to the engine and turn off the
engine.
Flash hazard lights as long as the battery has
power or until the hazard light button is
pressed. The hazard lights can be deacti -
vated by pressing the hazard light button.
Turn on the interior lights, which remain on
as long as the battery has power.
Unlock the power door locks.
NOTE:
After an accident, remember to cycle the igni -
tion to the STOP (OFF/LOCK) position and
remove the key from the ignition switch to avoid
draining the battery. Carefully check the vehicle
for fuel leaks in the engine compartment and on
the ground near the engine compartment and
fuel tank before resetting the system and
starting the engine. If there are no fuel leaks or damage to the vehicle electrical devices (e.g.
headlights) after an accident, reset the Fuel Cut
Off Switch by following the procedure described
below. If you have any doubt, contact an autho
-
rized dealer.
Fuel Cut Off Switch Reset Procedure
In order to reset the Fuel Cut Off Switch after an
event push the “A” Button located underneath
the instrument panel on the passenger side.

Fuel Cut Off Switch

Maintaining Your Air Bag System
WARNING!
If, after an accident, you smell fuel or see
leaks from the fuel system, do not reset the
Fuel Cut Off Switch to avoid the risk of fire.
Before resetting the Fuel Cut Off Switch,
carefully check for fuel leaks or damage to
the vehicle electrical devices (e.g.
headlights).
WARNING!
Modifications to any part of the air bag
system could cause it to fail when you need
it. You could be injured if the air bag system
is not there to protect you. Do not modify
the components or wiring, including adding
any kind of badges or stickers to the
steering wheel hub trim cover or the upper
passenger side of the instrument panel. Do
not modify the front bumper, vehicle body
structure, or add aftermarket side steps or
running boards.6

IN CASE OF EMERGENCY209
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service.
Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow
bars and other equipment designed for this
purpose, following equipment manufacturer’s
instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main
structural members of the vehicle, not to
fascia/bumper or associated brackets. State
and local laws regarding vehicles under tow
must be observed. If you must use the accessories (wipers,
defrosters, etc.) while being towed, the ignition
must be in the ON/RUN mode.
If the key fob is unavailable or the vehicle's
battery is discharged, for instructions on
shifting the automatic transmission out of
PARK (P) for towing Ú
