Programming Transmitters to
the Vehicle
Only RKE transmitters programmed
to this vehicle will work. If a
transmitter is lost or stolen, a
replacement can be purchased and
programmed through your dealer/
retailer. When the replacement
transmitter is programmed to this
vehicle using the DIC, all remaining
transmitters must also be
reprogrammed. Any lost or stolen
transmitters will no longer work once
the new transmitter is programmed.
Each vehicle can have up to
eight transmitters programmed to it.
See “Relearn Remote Key” under
DIC Operation and Displays
(With DIC Buttons) on page 3-46or
DIC Operation and Displays
(Without DIC Buttons) on page 3-51
for instructions on how to program
transmitters to this vehicle.
Battery Replacement
Replace the battery if the REPLACE
BATTERY IN REMOTE KEY
message displays in the DIC.Notice:When replacing the
battery, do not touch any of the
circuitry on the transmitter. Static
from your body could damage
the transmitter.
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 down. Replace with
a CR2032 or equivalent battery.
4. Snap the transmitter back
together.
Remote Vehicle Start
This vehicle may have a remote
starting feature that starts the engine
from outside of the vehicle.
If the vehicle has an automatic
climate control system, the climate
control system defaults to a
heating or cooling mode depending
on the outside temperatures. If
the vehicle does not have an
automatic climate control system,
the system turns on at the
setting the vehicle was set to when
the vehicle was last turned off.
If the vehicle has an automatic
climate control system and heated
seats, the heated seats turn on
during colder outside temperatures
and shut off when the key is
turned to ON/RUN. SeeHeated
Seats on page 1-5orHeated and
Cooled Seats on page 1-6for
more information.
Features and Controls 2-5

If the vehicle has a voltmeter gage
or a voltage display on the Driver
Information Center (DIC), you
may see the voltage move up or
down. This is normal. If there
is a problem, an alert will be
displayed.
The battery can be discharged at
idle if the electrical loads are
very high. This is true for all
vehicles. This is because the
generator (alternator) may not be
spinning fast enough at idle to
produce all the power that is needed
for very high electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling
fans, trailer loads, and loads
plugged into accessory power
outlets.EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator’s
output and the vehicle’s electrical
needs. It can increase engine
idle speed to generate more power,
whenever needed. It can temporarily
reduce the power demands of
some accessories.
Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,
this action may be noticeable
to the driver. If so, a Driver
Information Center (DIC) message
might be displayed, such as
BATTERY SAVER ACTIVE,
BATTERY VOLTAGE LOW, or
LOW BATTERY. If this message is
displayed, it is recommended
that the driver reduce the electrical
loads as much as possible. See
DIC Warnings and Messages
on page 3-56.Battery Run-Down
Protection
This feature helps prevent the
battery from being drained, if the
interior courtesy lamps, reading/map
lamps, visor vanity lamps or trunk
lamp are accidentally left on.
If any of these lamps are left on,
they automatically turn off after
10 minutes, if the ignition is off.
The lamps will not come back on
again until one of the following
occurs:
The ignition is turned on.
The exterior lamps control is
turned off, then on again.
The headlamps will timeout after
10 minutes, if they are manually
turned on before the ignition is off.

outlets. In this mode, the system
automatically selects outside
air. Recirculation cannot be selected
while in oor mode.
-(Defog):This mode clears
the windows of fog or moisture.
Air is directed to the windshield,
oor outlets, and side window vents.
When this mode is selected, the
system turns off recirculation
and runs the air conditioning unless
the outside temperature is less
than 40°F (4°C). Recirculation
cannot be selected while in the
defog mode. Do not drive the vehicle
until all the windows are clear.
0(Defrost):This mode quickly
clears the windshield of fog or frost.
Air is directed to the windshield
and side window vents, with some
to the oor vents. In this mode,
outside air is pulled inside the
vehicle. Recirculation cannot be

Using recirculation for long periods
of time could cause the air inside
of the vehicle to become too dry.
To prevent this from happening,
after the inside of the vehicle
has cooled, turn the recirculation
mode off.
The air conditioning system removes
moisture from the air, so a small
amount of water might drip under the
vehicle while idling or after turning off
the engine. This is normal.
@(Recirculation):Press to turn
the recirculation mode on or off.
An indicator light comes on when
recirculation is on. When the engine
is turned off, the recirculation mode
automatically turns off and must
be re-selected when the engine is

Highway Hypnosis
Always be alert and pay attention
to your surroundings while driving.
If you become tired or sleepy,
nd a safe place to park your
vehicle and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan
the road ahead and to the sides.
Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on at or rolling terrain. Tips for
driving in these conditions include:
Keep the vehicle serviced
and in good shape.
Check all uid levels and brakes,
tires, cooling system, and
transmission.
Going down steep or long hills,
shift to a lower gear.
{CAUTION
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.
4-12 Driving Your Vehicle

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.
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 6-3for more information.
Things that are especially important
in trailer operation are automatic
transmission uid, engine oil,
axle lubricant, 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.
Trailer Wiring Harness
The vehicle is equipped with the
following wiring harness for towing
a trailer.
4-32 Driving Your Vehicle

Basic Trailer Wiring
The trailer wiring harness, with a
seven-pin connector, is located
at the rear of the vehicle and is
tied to the vehicle’s frame.
The harness connector can be
plugged into a seven-pin universal
heavy-duty trailer connector
available through your
dealer/retailer.
The seven-wire harness contains
the following trailer circuits:
Yellow: Left Stop/Turn Signal
Dark Green: Right Stop/Turn
Signal
Brown: Taillamps
Black: Ground
Light Green: Back-up Lamps
Red/Black: Battery Feed
Dark Blue: Trailer Brake*
*The fuse for this circuit is installed
in the underhood electrical center,
but the wires are not connected.
They should be connected by your
dealer/retailer or a qualied
service center.
If the back-up lamp circuit is not
functional, contact your
dealer/retailer.If a remote (non-vehicle) battery is
being charged, press the Tow/Haul
mode switch located on the center
console near the climate controls.
