(Continued)
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

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.

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.

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.

30 GETTING TO KNOW YOUR VEHICLE
Easy Entry/Exit Seat — If Equipped
This feature provides automatic driver seat
positioning to enhance driver mobility when
entering and exiting the vehicle.
The distance the driver seat moves depends on
wh

ere you have the driver seat positioned when
you place the vehicle’s ignition in the OFF position.
When you place the vehicle’s ignition in the OFF
position, the driver seat will move about
2.4 inches (60 mm) rearward if the driver seat
pos

ition is greater than or equal to 2.7 inches
( 6
7.7 mm) forward of the rear stop. The seat will
r e
turn to its previously set position when you
place the vehicle’s ignition in the ACC or RUN
position.
The Easy Entry/Easy Exit feature is disabled
when the driver seat position is less than 0.9 of
an inch (22.7 mm) forward of the rear stop. At
th

is position, there is no benefit to the driver by
moving the seat for Easy Exit or Easy Entry.
When enabled in Uconnect Settings, Easy Entry
a n

d Easy Exit positions are stored in each memory
setting profile
Ú page 26.
NOTE:
The Easy Entry/Exit feature is enabled or disabled
t h
rough the programmable features in the
Uconnect system
Ú page 122.
HEATED SEATS — IF EQUIPPED
On some models, the front and rear seats may be
equipped with heaters located in the seat cushions
and seatbacks.
Front Heated Seats
The front heated seat control buttons are located
within the climate or controls screen of the
touchscreen.
You can choose from HI, LO, or OFF heat settings.
Th

e indicator arrows in touchscreen buttons
indicate the level of heat in use. Two indicator arrows will illuminate for HI, and one for LO.
Turning the heating elements off will return the
user to the radio screen.
Press the heated seat button
once to turn
the HI setting on.
Press the heated seat button a second time
to turn the LO setting on.
Press the heated seat button a third time to
turn the heating elements off.
If the HI-level setting is selected, the system will
a u

tomatically switch to LO-level after
approximately 60 minutes of continuous
ope

ration. At that time, the display will change
from HI to LO, indicating the change. The LO-level
setting will turn off automatically after
approximately 45 minutes.
NOTE:
Once a heat setting is selected, heat will be felt
within two to five minutes.
The engine must be running for the heated
seats to operate.
For information on use with the Remote Start
sy
stem, see Ú page 17.
WARNING!
Persons who are unable to feel pain to the
skin because of advanced age, chronic illness,
diabetes, spinal cord injury, medication,
alcohol use, exhaustion or other physical
condition must exercise care when using the
seat heater. It may cause burns even at low
temperatures, especially if used for long
periods of time.
Do not place anything on the seat or seatback
that insulates against heat, such as a blanket
or cushion. This may cause the seat heater to
overheat. Sitting in a seat that has been over
-
heated could cause serious burns due to the
i n

creased surface temperature of the seat.
