NOTE:
Changes or modifications not expressly
approved by the party responsible for compli -
ance could void the user’s authority to operate

Keyless Push Button Ignition
This feature allows the driver to operate the igni -
tion 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 oper -
ating positions; three of which are labeled and

tions are OFF, ACC, and ON/RUN. The fourth
position is START. During START, RUN will illumi -
nate.

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.

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.
How To Use Remote Start
All of the following conditions must be met
before the engine will remote start:
Transmission in PARK
Doors closed
Hood closed
Hazard switch off
Brake switch inactive (brake pedal not
pushed)
Battery at an acceptable charge level
PANIC button not pushed
Fuel meets minimum requirement
Water In Fuel Indicator Light is not illumi -
nated
Wait To Start Light Indicator Light is not illu -
minated
Malfunction Indicator Light is not illuminated

Do NOT grab the door handle when pushing the
door handle lock button. This could unlock the
door(s).

Do NOT Grab The Door Handle When Locking

NOTE:
After pushing the door handle lock button,
you must wait two seconds before you can
lock or unlock the doors, using either Passive
Entry door handle. This is done to allow you to
check if the vehicle is locked by pulling the
door handle, without the vehicle reacting and
unlocking.
The Passive Entry system depends on a key
fob that is not fully discharged of its coin
battery capacity.
When the key fob battery is low, the instru -
ment cluster will display a message indi -
cating that the key fob battery is low. Refer to
“Keys” in this chapter for further information.
The vehicle doors can also be locked by using
the key fob lock button or the lock button
located on the vehicle’s interior door panel.

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
manufactured after 1982. Do not use a
garage door opener without these safety
features.
