NOTE:
• The engine must be running for the heated seats to operate.
• The level of heat selected will stay on until the operator changes it.
Vehicles Equipped With Remote Start
On models that are equipped with remote start, the driver’s
seat can be programmed to come on during a remote start.
This feature can be programmed through the Uconnect
system. Refer to “Uconnect Settings” in “Multimedia” for
further information.
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 tempera -
tures, especially if used for long periods of time.
• Do not place anything on the seat or seatback that insu -
lates 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.2

Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration of
coolant is used. Use of the Air Recirculation 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 interior surface of the window.
• Keep all objects a safe distance from the window.

7. Temperature Gauge•The gauge pointer shows engine coolant temperature.The pointer positioned within the normal range indi -
cates that the engine cooling system is operating satis -
factorily.
•The gauge pointer will likely indicate a higher tempera -
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.WARNING!
A hot engine cooling system is dangerous. You or others
could be badly burned by steam or boiling coolant. You
may want to call an authorized dealer for service if your
vehicle overheats. If you decide to look under the hood
yourself, see “Servicing And Maintenance.” Follow the
warnings under the Cooling System Pressure Cap
paragraph.
CAUTION!
Driving with a hot engine cooling system could damage
your vehicle. If the temperature gauge reads “H,” pull

Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immediate
repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the ON/
RUN position. The light should illuminate for approximately
two seconds. The light should then turn off unless the
parking brake is applied or a brake fault is detected. If the
light does not illuminate, have the light inspected by an
authorized dealer.
The light also will turn on when the parking brake is applied
with the ignition switch in the ON/RUN position.
NOTE:
This light shows only that the parking brake is applied. It
does not show the degree of brake application. — Hood Open Warning Light
This warning light will illuminate when the hood is ajar/
open and not fully closed.
NOTE:
If the vehicle is moving, there will also be a single chime. — Vehicle Security Warning Light — If Equipped

This light will flash at a fast rate for approximately 15 seconds
when the vehicle security alarm is arming, and then will flash
slowly until the vehicle is disarmed.

— Engine Coolant Temperature Warning Light
This warning light warns of an overheated engine condition.
If the engine coolant temperature is too high, this indicator
will illuminate and a single chime will sound. If the tempera -
ture reaches the upper limit, a continuous chime will sound
for four minutes or until the engine is able to cool: whichever
comes first.
If the light turns on while driving, safely pull over and stop
the vehicle. If the A/C system is on, turn it off. Also, shift the
transmission into NEUTRAL and idle the vehicle. If the
temperature reading does not return to normal, turn the
engine off immediately and call for service.

STARTING AND OPERATING
STARTING THE ENGINE
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belt.
The starter should not be operated for more than 10-second
intervals. Waiting a few seconds between such intervals will
protect the starter from overheating.
WARNING!
• When leaving the vehicle, always make sure the keyless ignition node is in the "OFF" mode, remove the
key fob from the vehicle and lock the 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 alocation accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless
Enter-N-Go in the ACC or 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.
