NOTE:

When opening the driver's door with the ignition in
ON/RUN (engine not running), a chime will sound
to remind you to place the ignition in the OFF posi-
tion. In addition to the chime, the message will
d i

splay “Ignition Or Accessory On” in the cluster.

For more information on proper engine starting
procedures, see Ú page 81.
REMOTE START — IF EQUIPPED
This system uses the key fob to start the
engine conveniently from outside the
v
e
hicle while still maintaining security.
Remote Start is used to defrost windows in cold
we
ather, 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
r e
duce this range Ú page 254.
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 through the
Uconnect Settings). Then, the engine will start, and
the vehicle will remain in the Remote Start mode
for a 15
minute cycle. Pushing the Remote Start
bu

tton a third time shuts the engine off.
To drive the vehicle, push the unlock button, and
wi
th a valid Keyless Enter ‘n Go™ key fob in the
vehicle, press the brake pedal and place the
ignition in the ON/RUN position.
NOTE:
With Remote Start, the engine will only run for
15 minutes.
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.
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 unattended
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.
Do not leave the key fob in or near the vehicle,
or in a location accessible to children, and do
not leave the ignition of a vehicle equipped
with Keyless Enter ‘n Go™ in the ON/RUN
position. 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 buildup
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.
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.
WARNING!

GETTING TO KNOW YOUR VEHICLE 17
For security, power window operation is
disabled when the vehicle is in the Remote Start
mode.
Remote Start can only be used twice. The igni -
tion must be placed in the ON/RUN position

Malfunction Indicator Light is not illuminated
TO EXIT REMOTE START MODE
To drive the vehicle after starting the Remote Start
system, either push and release the unlock button
on the key fob to unlock the doors, or unlock the
vehicle using Keyless Enter ‘n Go™ — Passive Entry
via the door handles, and disarm the Vehicle

INSTRUMENT CLUSTER DISPLAY

Your vehicle is equipped with an instrument cluster
display, which offers useful information to the driver.
With the ignition in the OFF mode, opening/closing
of a door will activate the display for viewing, and
display the total miles, or kilometers, in the odometer. Your instrument cluster display is
designed to display important information about
your vehicle’s systems and features. Using a driver
interactive display located on the instrument panel,
your instrument cluster display can show you how
systems are working and give you warnings when
they are not. The steering wheel mounted controls
allow you to scroll through the main menus and
submenus. You can access the specific information
you want and make selections and adjustments.

LOCATION AND CONTROLS
The instrument cluster display features an
interactive display which is located in the
instrument cluster.
This system conveniently allows the driver to select
a


variety of useful information by pushing the
arrow buttons located on the left side of the
steering wheel. The instrument cluster display
menu items consist of the following:
Speedometer
Vehicle Info
Driver Assist — If Equipped
Fuel Economy
Trip
Audio
Messages
Screen Setup
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. It is recommended to call an authorized
dealer for service if your vehicle overheats.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge
reads “H,” pull over and stop the vehicle. Idle the
vehicle with the air conditioner turned off until
the pointer drops back into the normal range. If
the pointer remains on the “H,” turn the engine
off immediately and call an authorized dealer for
service.
