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.
The START/STOP ignition button has several
operating modes that are labeled and will
illuminate when in position. These modes are
OFF, ACC, ON/RUN, and START.
Keyless Push Button Ignition

The push button ignition can be placed in the
following modes: OFF

The engine is stopped
Some electrical devices (e.g. central locking,
alarm, etc.) are still available
ACC
Engine is not started
Some electrical devices are available (e.g.
power sunroof, power windows etc.)
ON/RUN
Driving position
All the electrical devices are available (e.g.
climate controls, heated seats, etc.)
START
The engine will start (when foot is on the
brake)
NOTE:
If the ignition switch does not change the mode
by pushing the 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 and push to
operate the ignition switch.

Back Up Starting Method

1 — OFF
2 — ACC (Accessory)
3 — ON/RUN
WARNING!
When exiting the vehicle, always remove
the key fob from the vehicle and lock your
vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the gear selector.

NOTE:
The key fob may not be detected by the
vehicle Keyless Enter-N-Go system if it is
located next to a mobile phone, laptop or
other electronic device; these devices may
block the key fob’s wireless signal and prevent the Keyless Enter-N-Go system from
starting the vehicle.
Engine starting procedure Ú
page 140.
When opening the driver's door and the igni -
tion is in the ON/RUN position (engine not
running), a chime will sound to remind you to
place the ignition in the OFF position. In addi -
tion to the chime, the message “Ignition or
Accessory ON” will display in the cluster.
REMOTE START — IF EQUIPPED
(GASOLINE)
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).
Remote start is used to defrost windows in cold
weather and to reach a comfortable climate in
all ambient conditions before the customer
enters the vehicle. NOTE:
Obstructions between the vehicle and key fob
may reduce this range.
HOW TO USE REMOTE START
Push and release the Remote Start button on
the key fob twice within five seconds. The
vehicle doors will lock, the parking lights will
flash, and the horn will chirp twice (if
programmed). Then, the engine will start, and
the vehicle will remain in the Remote Start
mode for a 15 minute cycle.
Pushing the remote start button a third time
shuts the engine off.
Do not leave the key fob in or near the
vehicle, or in a location accessible to chil-
dren, and do not leave the ignition of a
vehicle equipped with Keyless Enter-N-Go
in the ON/RUN mode. A child could operate
power windows, other controls, or move the
vehicle.
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
CAUTION!
An unlocked vehicle is an invitation for
thieves. Always remove key fob from the
vehicle and lock all doors when leaving the
vehicle unattended.

The Vehicle Security system is designed to
protect your vehicle. However, you can create
conditions where the system will give you a false
alarm. If one of the previously described arming
sequences has occurred, the Vehicle Security
system will arm regardless of whether you are in
the vehicle or not. If you remain in the vehicle
and open a door, the alarm will sound. If this
occurs, disarm the Vehicle Security system.
If the Vehicle Security system is armed and the
battery becomes disconnected, the Vehicle
Security system will remain armed when the
battery is reconnected; the exterior lights will
flash, and the horn will sound. If this occurs,
disarm the Vehicle Security system.
REARMING OF THE SYSTEM
If something triggers the alarm, and no action is
taken to disarm it, the Vehicle Security system
will turn the horn off after 29 seconds, five
seconds between cycles, and up to eight cycles
if the trigger remains active. The Vehicle
Security system will then rearm itself.
