chime, the message “Ignition ON” will display in
the cluster.
REMOTE START — IF EQUIPPED
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
328 ft (100 m).
Remote Start is used to defrost windows in cold
weather, and to reach a comfortable climate in all
ambient conditions before the driver enters the
vehicle.
NOTE:Obstructions between the vehicle and key fob may
reduce this range Ú page 408.
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.
NOTE:
If the Remote Start button on the key fob is
pushed too rapidly during activation, the vehicle
may not start.
With Remote Start, the engine will only run for
15 minutes.
Remote Start can only be used twice.
If an engine fault is present or fuel level is low,
the vehicle will start and then shut down in 10
seconds.
The parking lights will turn on and remain on
during Remote Start mode.
Headlight animation (if equipped) will occur
when Remote Start is activated, if “Headlight
Illumination On Approach” is enabled within
Uconnect Settings.
For security, power window and power sunroof
operation (if equipped) are disabled when the
vehicle is in the Remote Start mode.
The ignition must be placed in the ON/RUN posi -
tion before the Remote Start sequence can be
repeated for a third cycle.
WARNING!
Do not start or run an engine in a closed
garage or confined area. Exhaust gas contains
carbon monoxide (CO) which is odorless and
colorless. Carbon monoxide is poisonous and
can cause serious injury or death when
inhaled.
Keep key fobs away from children. Operation
of the Remote Start system, windows, door
locks or other controls could cause serious
injury or death.

There are five situations that trigger a FOBIK-Safe
search in any Passive Entry vehicle:
A lock request is made by a valid Passive Entry
key fob while a door is open.
A lock request is made by the Passive Entry door
handle while a door is open.
A lock request is made by the door panel switch
while the door is open.
When the Vehicle Security system is in pre-arm
or armed status and the liftgate transitions from
opened to closed.
When the liftgate transitions from open to
closed and Remote Start is active.
When any of these situations occur, after all open
doors are shut, the FOBIK-Safe search will be
executed. If it detects a Passive Entry key fob
inside the vehicle, the vehicle will unlock and alert
the customer.
NOTE:The vehicle will only unlock the doors when a valid
Passive Entry key fob is detected inside the
vehicle. The vehicle will not unlock the doors when
any of the following conditions are true:
The doors are manually locked using the emer -
gency lock lever.
Three attempts are made to lock the doors
using the door panel switch and then the doors
are closed.
There is a valid Passive Entry key fob outside the
vehicle within 5 ft (1.5 m) of a Passive Entry
door handle.
To Lock The Vehicle’s Doors And Liftgate
