Engine is not started.
Some electrical devices are available
(e.g. power windows etc.).
RUN
Driving position.
All the electrical devices are available
(e.g. climate controls, heated seats, etc.).

Back Up Starting Method

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.
For more information on the engine starting
procedure, see Ú page 118.
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.

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 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.

dangerous. Moving a seat while driving could
result in loss of control which could cause a
collision and serious injury or death.

Seats should be adjusted before fastening
the seat belts and while the vehicle is
parked. Serious injury or death could result
from a poorly adjusted seat belt.

Easy Entry/Exit Seat
This feature provides automatic driver’s seat
positioning to enhance driver mobility when
entering and exiting the vehicle. The distance the driver’s seat moves depends
on where you have the driver’s seat positioned
when you remove the key fob from the ignition.
When you place the ignition in the OFF posi
-
tion, the driver’s seat will move about
2.4 inches (60 mm) rearward if the driver’s seat position is greater than or equal to
2.7 inches (67.7 mm) forward of the rear stop. The seat will return to its previously set
position when you place the ignition into the
ACC or RUN position.

When you place the ignition in the OFF position,
the driver’s seat will move to a position
0.3 inches (7.7 mm) forward of the rear stop if
the driver’s seat position is between 0.9 inches
and 2.7 inches (22.7 mm and 67.7 mm) forward of the rear stop. The seat will return to its previ-
ously set position when you place the ignition to
the ACC or RUN position.

The Easy Entry/Exit feature is disabled when
the driver’s seat position is less than
0.9 inches (22.7 mm) forward of the rear stop.
At this 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
and Easy Exit positions are stored in each
memory setting profile Ú
page 32.
NOTE:
The Easy Entry/Exit feature is enabled or
disabled through the programmable features in
the Uconnect system Ú page 228.
HEATED SEATS — IF EQUIPPED
On some models, the front and rear seats may
be equipped with heaters located in the seat
cushions and seat backs.
WARNING!
Persons who are unable to feel pain to the
skin because of advanced age, chronic
illness, diabetes, spinal cord injury, medica -
tion, alcohol use, exhaustion or other phys -
ical 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.

The level of heat selected will stay on until
the operator changes it.
For information on use with the Remote Start
system, see Ú page 21.
Rear Heated Seats
On some models, the two outboard rear seats
are equipped with heated seats. The heated
seat switches for these seats are located on the
rear of the center console.
There are two heated seat switches that allow
the rear passengers to operate the seats
independently. You can choose from HI, MED,
LO, or OFF heat settings. Amber indicator lights
in each switch indicate the level of heat in use.

NOTE:
The level of heat selected will stay on until
the operator changes it.
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.
VENTILATED SEATS — IF EQUIPPED
Front Ventilated Seats

Located in the seat cushion are small fans that
draw the air from the passenger compartment
and move air through fine perforations in the seat
cover to help keep the driver and front passenger
cooler in higher ambient temperatures. The fans
operate at three speeds, HI, MED and LO.

Do not place anything on the seat or seat -
back 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 overheated could cause serious
burns due to the increased surface
temperature of the seat.
