Vehicles Equipped With Remote Start
On models that are equipped with remote start, the heated seats can be programmed
to come on during a remote start.
This feature can be programmed through the Uconnect system. Refer to “Uconnect
Settings” in “Understanding Your Instrument Panel” in the Owner's Manual on the
DVD.
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 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 overheated could cause serious burns due to the increased
surface temperature of the seat.

STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function was developed to reduce fuel consumption. The system will
stop the engine automatically during a vehicle stop if the required conditions are
met. Releasing the brake pedal or pressing the accelerator pedal will automatically
re-start the engine.
Automatic Mode
The Stop/Start feature is enabled after every normal customer
engine start. At that time, the system will go into STOP/START
READY and if all other conditions are met, can go into a STOP/
START AUTOSTOP ACTIVE “Autostop” mode.
To Activate The Autostop Mode, The Following Must Occur:
• The system must be in STOP/START READY state. A STOP/START READY message will be displayed in the Driver Information Display (DID) within the
Stop/Start section. Refer to “Driver Information Display (DID)” in “Understanding
Your Instrument Panel” in your owner’s manual on the DVD for further information.
• The vehicle must be completely stopped.
• The shifter must be in a forward gear and the brake pedal depressed.
The engine will shut down, the tachometer will move to the zero position and the
Stop/Start telltale will illuminate indicating you are in Autostop. Customer settings
will be maintained upon return to an engine running condition.
Refer to the “Stop/Start System” in the “Starting And Operating” section located in
your Owner’s Manual on the DVD for further information.
Possible Reasons The Engine Does Not Autostop
Prior to engine shut down, the system will check many safety and comfort conditions
to see if they are fulfilled. Detailed information about the operation of the Stop/Start
system may be viewed in the DID Stop/Start Screen. In the following situations, the
engine will not stop:
• Driver’s seat belt is not buckled.
• Driver’s door is not closed.
• Battery temperature is too warm or cold.
• Battery charge is low.
• The vehicle is on a steep grade.
• Cabin heating or cooling is in process and an acceptable cabin temperature has not been achieved.
• HVAC is set to full defrost mode at a high blower speed.

Adding Diesel Exhaust Fluid
The DEF gauge (located in the DID) will display the level of DEF remaining in the
tank.
Completely fill the DEF tank through the diesel exhaust fluid fill location (located
behind the fuel door) at every maintenance interval or before if prompted by the
Driver Information Display (DID).
NOTE:
• The gauge may take up to five seconds to update after adding a gallon or more ofDiesel Exhaust Fluid (DEF) to the DEF tank. If you have a fault related to the DEF
system, the gauge may not update to the new level. See your authorized dealer for
service.
• The DEF gauge may also not immediately update after a refill if the temperature of the DEF fluid is below 12F (-11C). The DEF line heater will possibly warm up the
DEF fluid and allow the gauge to update after a period of run time. Under very cold
conditions, it is possible that the gauge may not reflect the new fill level for several
drives.
NOTE:
• Driving conditions (altitude, vehicle speed, load, etc.) will effect the
amount of DEF that is used in your
vehicle.
• Since DEF will begin to freeze at 12°F (-11°C), your vehicle is equipped with
an automatic DEF heating system.
This allows the DEF injection system to
operate properly at temperatures be-
low 12°F (-11°C).

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the potential for overheating by
taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but do notincrease the engine idle speed while preventing vehicle motion with the brakes.
NOTE:
There are steps that you can take to slow down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum heat, the mode control to floor and the blower control to high. This allows the heater core to act as a
supplement to the radiator and aids in removing heat from the engine cooling
system.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature
gauge reads HOT (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 HOT (H), and you hear continuous chimes, turn the engine off
immediately and call for service.
WARNING!
You or others can be badly burned by hot engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming from under the hood, do not open
the hood until the radiator has had time to cool. Never try to open a cooling system
pressure cap when the radiator or coolant bottle is hot.
WHAT TO DO IN EMERGENCIES

NOTE:
Push the "ESC Off" switch (if necessary), to place the Electronic Stability Control
(ESC) system in "Partial Off" mode, before rocking the vehicle. Refer to “Electronic
Brake Control” in “Starting And Operating” in the Owners Manual on the DVD for
further information. Once the vehicle has been freed, push the "ESC Off" switch
again to restore "ESC On" mode.
CAUTION!
Racing the engine or spinning the wheels may lead to transmission overheating
and failure. Allow the engine to idle with the transmission in NEUTRAL for at least
one minute after every five rocking-motion cycles. This will minimize overheating
and reduce the risk of transmission failure during prolonged efforts to free a stuck
vehicle.
WARNING!
Fast spinning tires can be dangerous. Forces generated by excessive wheel speeds
may cause damage, or even failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels faster than 30 mph (48 km/h)
or for longer than 30 seconds continuously without stopping when you are stuck
and do not let anyone near a spinning wheel, no matter what the speed.
CAUTION!
• When “rocking” a stuck vehicle by shifting between DRIVE and REVERSE, donot spin the wheels faster than 15 mph (24 km/h), or drivetrain damage may
result.
• Revving the engine or spinning the wheels too fast may lead to transmission
overheating and failure. It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmission shifting occurring).
WHAT TO DO IN EMERGENCIES
215

WARNING!
• Overloading of your tires is dangerous. Overloading can cause tire failure,affect vehicle handling, and increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never overload them.
• Improperly inflated tires are dangerous and can cause collisions. Under-
inflation increases tire flexing and can result in over-heating and tire failure.
Over-inflation reduces a tire’s ability to cushion shock. Objects on the road and
chuck holes can cause damage that results in tire failure. Unequal tire
pressures can cause steering problems. You could lose control of your vehicle.
Over-inflated or under-inflated tires can affect vehicle handling and can fail
suddenly, resulting in loss of vehicle control. Always drive with each tire
inflated to the recommended cold tire inflation pressure.
ADDING FUEL
1. Push the fuel filler door release switch (located under the headlamp switch).
