IGNITION SWITCH
KEYLESS PUSH BUTTON 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

REMOTE START— IF EQUIPPED (DIESEL)
This system uses the key fob to start
the engine conveniently from outside
the vehicle while still maintaining
security. The system has a range of
approximately 300 ft (91 m).
NOTE:
Obstructions between the vehicle and the
key fob may reduce this range.
The Remote Start system will wait for the
Wait To Start indicator light to extinguish
before cranking the engine. This allows time
for the intake heater to preheat the incoming
air, and is normal operation in cold weather.
Refer to “Wait To Start Light”, located in
“Warning Lights And Messages” in “Getting
To Know Your Instrument Panel” for more
information.

24GETTING TO KNOW YOUR VEHICLE
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.

KEY PROGRAMMING
Programming key fobs may be performed at an
authorized dealer.
REPLACEMENT KEYS
NOTE:
Only key fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle. Once a key fob is
programmed to a vehicle, it cannot be
programmed to any other vehicle. NOTE:
Duplication of key fobs may be performed at an
authorized dealer. This procedure consists of
programming a blank key fob to the vehicle
electronics. A blank key fob is one that has
never been programmed.
When having the Sentry Key Immobilizer
System serviced, bring all vehicle keys with you
to an authorized dealer.

Always remove the key fobs from the
vehicle and lock all doors when leaving the
vehicle unattended.
For vehicles equipped with Keyless
Enter-N-Go — Ignition, always remember to

WARNING!
Vehicle exhaust contains carbon monoxide,
a dangerous gas. Do not run your vehicle in
the garage while programming the trans -
ceiver. Exhaust gas can cause serious
injury or death.

Your motorized door or gate will open and
close while you are programming the
universal transceiver. Do not program the
transceiver if people, pets or other objects are
in the path of the door or gate. Only use this
transceiver with a garage door opener that
has a “stop and reverse” feature as required
by Federal safety standards. This includes
most garage door opener models manufac -
tured after 1982. Do not use a garage door
opener without these safety features.

NOTE:
If the vehicle is equipped with a premium center
console with double (tandem) doors, push the
front bin door to access the cupholders.
Vehicles Equipped With 40/20/40 Seats
The cupholders are located on the backside of
the center portion of the front seat (20). Fold

ELECTRICAL POWER OUTLETS
The auxiliary 12 Volt (13 Amp) power outlet can
provide power for in-cab accessories designed
for use with the standard “cigar lighter” plug.
The 12 Volt power outlets and 5 Volt (2.5 Amp)
USB Port (Charge Only) have a cap attached to
the outlet indicating “12V DC”, together with
either a key symbol, battery symbol, or USB
symbol.
A key symbol indicates that the key must be in
the ON/RUN or ACC position for the outlet to
provide power. The battery symbol indicates
that the outlet is connected to the battery, and
can provide power at all times.

An auxiliary power outlet can be found in the
tray on top of the center stack. This power outlet
works when the ignition is in the ON/RUN, ACC,
or OFF position.

When the vehicle is turned off, be sure to
unplug any equipment as to not drain the
battery of the vehicle. All accessories connected
to the outlet(s) should be removed or turned off
when the vehicle is not in use to protect the
battery against discharge.
CAUTION!
Do not exceed the maximum power of
160 Watts (13 Amps) at 12 Volts. If the
160 Watts (13 Amps) power rating is
exceeded, the fuse protecting the system
will need to be replaced.

Power outlets are designed for accessory
plugs only. Do not insert any other object in
the power outlets as this will damage the
outlet and blow the fuse. Improper use of the
power outlet can cause damage not covered
by your New Vehicle Limited Warranty.

WARNING!
To avoid serious injury or death:
Only devices designed for use in this type of
outlet should be inserted into any 12 Volt
outlet.
Do not touch with wet hands.
Close the lid when not in use and while
driving the vehicle.
If this outlet is mishandled, it may cause an
electric shock and failure.
CAUTION!
Many accessories that can be plugged in
draw power from the vehicle's battery, even
when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the
vehicle's battery will discharge sufficiently
to degrade battery life and/or prevent the
engine from starting.
Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.), will
discharge the battery even more quickly.
Only use these intermittently and with
greater caution.
After the use of high power draw accesso -
ries, or long periods of the vehicle not being
started (with accessories still plugged in),
the vehicle must be driven a sufficient
length of time to allow the generator to
recharge the vehicle's battery.
WARNING! (Continued)
