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 where you have the driver seat positioned
when you place the vehicle’s ignition in the
OFF position.
Each stored memory setting will have an
associated Easy Entry and Easy Exit position.
NOTE:
The Easy Entry/Exit feature is not enabled
when the vehicle is delivered from the
factory. The Easy Entry/Exit feature is
enabled (or later disabled) through the
programmable features in the Uconnect
system.
Refer to “Uconnect Settings” in “Multi -
media” in the Owner’s Manual for further
information.
Heated Seats
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, medication, alcohol use, exhaus-
tion or other physical condition must
exercise care when using the seat heater.
It may cause burns even at low tempera-
tures, 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 overheated could
cause serious burns due to the increased
surface temperature of the seat.

The temperature can be displayed in U.S.
or Metric units by selecting the US/Metric
customer-programmable feature. Refer to
the “Uconnect Settings” in “Multimedia”
in your Owner’s Manual for further infor-
mation.

Automatic mode during cold start-ups, the
blower fan will remain on low until the
engine warms up. The blower will increase in
speed and transition into Auto mode.
Manual Operation Override
This system offers a full complement of
manual override features. The AUTO symbol

mode.
Operating Tips
NOTE:
For suggested control settings for various
weather conditions, refer to “Climate
Controls” in “Getting To Know Your Vehicle”
in the Owner’s Manual.
Summer Operation
The engine cooling system must be
protected with a high-quality antifreeze
coolant to provide proper corrosion protec -
tion and to protect against engine over -
heating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and
defroster performance, make sure the engine
cooling system is functioning properly and
the proper amount, type, and concentration
of coolant is used. Use of the Air Recircula -
tion mode during Winter months is not
recommended, because it may cause window
fogging.
Vacation/Storage
Before you store your vehicle, or keep it out
of service (i.e., vacation) for two weeks or
more, run the air conditioning system at idle
for about five minutes, in fresh air with the
blower setting on high. This will ensure
adequate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in
mild, rainy, and/or humid weather. To clear
the windows, select Defrost or Mix mode and
increase the front blower speed. Do not use
the Recirculation mode without A/C for long
periods, as fogging may occur.
CAUTION!
Failure to follow these cautions can cause
damage to the heating elements:
Use care when washing the inside of the
rear window. Do not use abrasive window
cleaners on the interior surface of the
window. Use a soft cloth and a mild
washing solution, wiping parallel to the
heating elements. Labels can be peeled
off after soaking with warm water.
Do not use scrapers, sharp instruments,
or abrasive window cleaners on the inte-
rior surface of the window.
Keep all objects a safe distance from the
window.

The system only warns the tire pressure is
low: it is not able to inflate them.
Yellow Indicator Lights — Active Speed Limiter Fault Indicator
Light — If Equipped
This warning light will illuminate to signal
when there is a fault detected with the Active
Speed Limiter.
— Forward Collision Warning Off
Indicator Light — If Equipped
This light indicates that Forward Collision
Warning is off.
— 4WD Low Indicator Light — If
Equipped
This light alerts the driver that the vehicle is
in the four-wheel drive LOW mode. The front
and rear driveshafts are mechanically locked
together forcing the front and rear wheels to
rotate at the same speed. Low range provides
a greater gear reduction ratio to provide
increased torque at the wheels.
Refer to “Four-Wheel Drive Operation” in
“Starting And Operating” for further informa -
tion on four-wheel drive operation and proper
use.
— Rear Axle Lock Indicator Light
This light indicates when the rear axle lock
has been activated.
— Rear Fog Indicator — If Equipped
This indicator light will illuminate when the
rear fog lights are on.
— Glow Plug Light — If Equipped
This vehicle will inhibit engine cranking
when the ambient temperature is less than
–22° F (–30° C) and the oil temperature
sensor reading indicates an engine block
heater has not been used. The Glow Plug
light will flash during in cold weather for up
to ten seconds.
If equipped with a block heater harness the
message “Plug In Engine Heater”, will be
displayed in the instrument cluster when the
ambient temperature is below 5°F (-15° C) at
the time the engine is shut off as a reminder
to avoid possible crank delays at the next
cold start.
CAUTION!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system operation
or sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Using
aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using
an aftermarket tire sealant it is
recommended that you take your vehicle to
an authorized dealer to have your sensor
function checked.

system could cause it to fail when you
need it. You could be injured if the air
bag system is not there to protect you.
Do not modify the components or wiring,
including adding any kind of badges or
stickers to the steering wheel hub trim
cover or the upper passenger side of the
instrument panel. Do not modify the
front bumper, vehicle body structure, or
add aftermarket side steps or running
boards.

systems of your vehicle, particularly the igni
-
tion and engine fuel supply control units.
1. Apply the parking brake, shift the auto -
matic transmission into PARK (manual
transmission in NEUTRAL) and turn the
ignition OFF.
2. Turn off the heater, radio, and all unnec -
essary electrical accessories.
3. If using another vehicle to jump start the battery, park the vehicle within the
jumper cables reach, apply the parking
brake and make sure the ignition is OFF.
Jump Starting Procedure
WARNING!
Take care to avoid the radiator cooling
fan whenever the hood is raised. It can
start anytime the ignition switch is ON.

Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact.
You could be seriously injured.
Batteries contain sulfuric acid that can
burn your skin or eyes and generate
hydrogen gas which is flammable and
explosive. Keep open flames or sparks
away from the battery.
WARNING! (Continued) WARNING!

Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.

WARNING!
Failure to follow this jump starting
procedure could result in personal injury or
property damage due to battery explosion.
CAUTION!
Failure to follow these procedures could
result in damage to the charging system of
the booster vehicle or the discharged
