Battery Replacement
Replace the battery if the KEY FOB BATT LOW
message displays in the DIC. See “KEY FOB BATT
LOW” underDIC Warnings and Messages on page 3-46.
Notice:When replacing the battery, do not touch
any of the circuitry on the transmitter. Static
from your body could damage the transmitter.
To replace the battery:
1. Separate the transmitter with a at, thin object
inserted into the notch on the side.
2. Remove the old battery. Do not use a metal object.3. Insert the new battery, positive side facing up.
Replace with a CR2032 or equivalent battery.
4. Snap the transmitter back together.
Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine from outside
the vehicle. It may also start the vehicle’s heating or air
conditioning systems and rear window defogger. When
the remote start system is active and the vehicle has an
automatic climate control system, it will automatically
regulate the inside temperature. Normal operation of
the system will return after the ignition key is turned
to ON/RUN.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require
a person using remote start to have the vehicle in view
when doing so. Check local regulations for any
requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
The remote start feature provides two separate starts
per ignition cycle, each with 10 minutes of engine
running time.

Automatic Operation
AUTO (Automatic):Select AUTO on both the fan
speed control and the air delivery mode control knobs to
activate the automatic system. Automatic operation
controls the inside temperature and air delivery.
Use the steps below to place the climate control system
in automatic mode:
1. Turn the fan knob and the air delivery mode knob
to AUTO.
The display shows the current set temperature.
When auto is selected, the air conditioning operation
and air inlet is automatically controlled. The air
conditioning compressor runs when the outside
temperature is over about 40°F (4°C). The air inlet
is normally set to outside air. If it is hot outside,
the air inlet can automatically switch to recirculate
inside air to help quickly cool down the vehicle.
2. Set the temperature.
To nd your comfort setting, start with an initial
temperature setting and allow about 20 minutes for
the system to regulate. Press
wandxto adjust
the temperature setting as necessary. If the
temperature setting of 60°F (15°C) is chosen the
system remains at the maximum cooling setting.

When air conditioning is selected or in AUTO mode, the
system runs the air conditioning automatically to cool
and dehumidify the air entering the vehicle.
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for
the vehicle to cool down. Then keep the windows closed
for the air conditioner to work its best.
On cool, but sunny days while using manual operation
of the automatic system, use bi-level to deliver warm
air to the oor and cooler air to the instrument
panel outlets. To warm or cool the air, press
xorwto
the desired temperature setting.
In AUTO mode the system cools and dehumidies the
air inside the vehicle. Also, the system maximizes
its performance by using recirculation as necessary.
Heating:On cold days when using manual operation of
the automatic system, choose oor mode to deliver
air to the oor outlets. To warm or cool the air delivered,
adjust the temperature to the desired setting.
To use the automatic mode, turn the knob to AUTO and
adjust the temperature by pressing
xorw.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear):Press to turn the rear window defogger on
or off. An indicator light above the button comes on
to indicate that the rear window defogger is on.
If driving below 50 mph (80 km/h), the rear window
defogger turns off about 15 minutes after the button is
pressed. If turned on again, the defogger only runs
for about seven and one-half minutes before turning off.
If the vehicle’s speed is maintained above 50 mph
(80 km/h), the rear window defogger remains on once
the button is pressed.
If the vehicle has the remote start feature, the rear
defogger automatically turns on if it is cold outside,
but the indicator light does not come on. When
the vehicle transitions out of remote start mode the rear
defogger turns off.
Notice:Do not use a razor blade or sharp object
to clear the inside rear window. Do not adhere
anything to the defogger grid lines in the rear glass.
These actions may damage the rear defogger.
Repairs would not be covered by your warranty.

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, the light comes
on and a chime sounds, the engine is too hot. It means
that the engine coolant has overheated. SeeEngine
Overheating on page 5-37.
Tire Pressure Light
For vehicles with a tire
pressure light, this light
comes on briey when the
engine is started and
provides information about
tire pressures and the
Tire Pressure Monitoring
System.
When the Light is On Steady
This indicates that one or more of the tires is signicantly
underinated.
A tire pressure message in the Driver Information Center
(DIC), can accompany the light. SeeDIC Warnings and
Messages on page 3-46for more information. Stop and
check the tires as soon as it is safe to do so. If a tire is
underinated, inate to the proper pressure. SeeTires on
page 5-59for more information.
When the Light Flashes First and Then is
On Steady
This indicates that there could be a problem with the Tire
Pressure Monitor System. The light ashes for about
a minute and stays on steady for the remainder of the
ignition cycle. This sequence repeats with every ignition
cycle. SeeTire Pressure Monitor System on page 5-69
for more information. United States

When towing a trailer, the arrows on the instrument panel
ash for turns even if the bulbs on the trailer are burned
out. For this reason you may think other drivers are
seeing the signal when they are not. It is important to
check occasionally to be sure the trailer bulbs are still
working.
Driving on Grades
Notice:Do not tow on steep continuous grades
exceeding 6 miles (9.6 km). Extended, higher
than normal engine and transmission temperatures
may result and damage the vehicle. Frequent
stops are very important to allow the engine and
transmission to cool.
Reduce speed and shift to a lower gearbeforestarting
down a long or steep downgrade. If the transmission is
not shifted down, the brakes might have to be used so
much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce the
vehicle’s speed to around 45 mph (70 km/h) to reduce
the possibility of the engine and the transmission
overheating. If the engine does overheat, seeEngine
Overheating on page 5-37.
Parking on Hills
{CAUTION:
Parking the vehicle on a hill with the trailer attached
can be dangerous. If something goes wrong, the rig
could start to move. People can be injured, and
both the vehicle and the trailer can be damaged.
When possible, always park the rig on a at
surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park)
yet. Turn the wheels into the curb if facing downhill
or into traffic if facing uphill.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release the
brake pedal until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking
brake and shift the transmission into P (Park).
5. Release the brake pedal.
4-35

Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
start the engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
The vehicle needs service more often when pulling a
trailer. SeeScheduled Maintenance on page 6-4for more
information. Things that are especially important in traileroperation are automatic transmission uid, engine oil,
belts, cooling system and brake system. It is a good
idea to inspect these before and during the trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
The cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-37.
Changing a Tire When Trailer Towing
If the vehicle gets a at tire while towing a trailer,
be sure to secure the trailer and disconnect it from the
vehicle before changing the tire.
