Lighting 6-7
Battery Power Protection
This vehicle has a feature to help
prevent the battery from being
drained in case any of the following
lamps are left on; the underhood
lamp, if your vehicle has this
feature, vanity mirror lamps, cargo
lamps, reading lamps, console
or glove box lamps. If any of
these lamps are left on, they will
automatically time-out after about
10 minutes. To reset it, all of the
above lamps must be turned off
or the ignition key on.
Exterior Lighting Battery
Saver
If the manual parking lamps or
headlamps have been left on,
the exterior lamps will turn off as
soon as the ignition is turned off or
Retained Accessory Power (RAP)
is active. This protects against
draining the battery in case you
have accidentally left the headlamps
or parking lamps on. The battery
saver does not work if the
headlamps are turned on after the
ignition switch is turned to off.
If you need to leave the lamps on,
use the exterior lamp control to turn
the lamps back on.

Infotainment System 7-11
XM™Satellite Radio Service
XM Satellite Radio Service gives
digital radio reception from coast
to coast in the 48 contiguous
United States, and in Canada.
Just as with FM, tall buildings or
hills can interfere with satellite radio
signals, causing the sound to fade
in and out. In addition, traveling
or standing under heavy foliage,
bridges, garages, or tunnels may
cause loss of the XM signal for a
period of time.
Cellular Phone Usage
Cellular phone usage may cause
interference with the vehicle's radio.
This interference may occur when
making or receiving phone calls,
charging the phone's battery,
or simply having the phone on.
This interference causes an
increased level of static while
listening to the radio. If static is
received while listening to the
radio, unplug the cellular phone
and turn it off.
Diversity Antenna System
The AM-FM antenna is a hidden
self tuning system. It optimizes the
AM and FM signals relative to the
vehicle's position and radio station
source. No maintenance or
adjustments are needed.
Satellite Radio Antenna
For vehicles with XM Satellite Radio
Service, the antenna is located on
the roof or on the trunk lid of the
vehicle. Keep the antenna clear
of obstructions for clear radio
reception.
Audio Players
CD Player
Care of the CD Player
Do not add labels to a CD, it could
get caught in the CD player. Use a
marking pen to write on the top of
the CD if a description is needed.
Do not use CD lens cleaners, they
could damage the CD player.
Notice: If a label is added to a
CD, or more than one CD is
inserted into the slot at a time,
or an attempt is made to play
scratched or damaged CDs, the
CD player could be damaged.
While using the CD player, use
only CDs in good condition
without any label, load one CD at
a time, and keep the CD player
and the loading slot free of
foreign materials, liquids, and
debris.
If an error displays, see “CD
Messages” later in this section.

Climate Controls 8-7
Maintenance
Passenger Compartment
Air Filter
The passenger compartment air
filter removes certain particles from
the air including pollen and dust
particles. Reductions in airflow,
which may occur more often in
dusty areas, indicate that the
filter may need to be replaced.
SeeMaintenance Replacement
Parts on page 11‑8.
Notice: Driving without a
passenger compartment air filter
in place can cause water and
small particles, like paper and
leaves, to be pulled into your
climate control system which may
cause damage to it. Make sure
you always replace the old filter
with a new one. The passenger compartment air
filter is located on the passenger
side of the engine compartment
near the battery. See
Engine
Compartment Overview on
page 10‑10.
To check or replace the air filter:
1. Remove the cover retainer clips (A) from the passenger
compartment air filter cover.
2. Remove the cover.
3. Remove the filter and install the new air filter.
4. Replace the filter cover.
5. Attach the retainer clips.

Driving and Operating 9-13
Run the engine for short periods
only as needed to keep warm, but
be careful.
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine
runs faster than the idle speed.
This keeps the battery charged to
restart the vehicle and to signal for
help with the headlamps. Do this
as little as possible to save fuel.If the Vehicle is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method.
{WARNING
If the vehicle's tires spin at high
speed, they can explode, and
you or others could be injured.
The vehicle can overheat,
causing an engine compartment
fire or other damage. Spin the
wheels as little as possible and
avoid going above 55 km/h
(35 mph) as shown on the
speedometer.
For information about using tire
chains on the vehicle, see Tire
Chains on page 10‑80.
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around
the front wheels. Turn off any
traction system. Shift back and forth
between R (Reverse) and a forward
gear, or with a manual transmission,
between 1 (First) or 2 (Second) and
R (Reverse), spinning the wheels
as little as possible. To prevent
transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the transmission is in gear.
Slowly spinning the wheels in the
forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not
get the vehicle out after a few
tries, it might need to be towed out.
If the vehicle does need to be towed
out, see Towing the Vehicle on
page 10‑86.

9-22 Driving and Operating
Cell phone chargers can interfere
with the operation of the Keyless
Access System. Battery chargers
should not be plugged in when
starting or turning off the engine.
To start the vehicle, do the following:
1. For vehicles with an automatictransmission, with your foot
on the brake pedal, press the
START button located on the
instrument panel. For vehicles
with a manual transmission, you
must also press in the clutch
pedal while pressing the START
button.
If there is not a keyless access
transmitter in the vehicle or if
there is something causing
interference with it, the DIC will
display NO FOBS DETECTED.
See Key and Lock Messages on
page 5‑42 for more information. 2. When the engine begins
cranking, let go of the button and
the engine cranks automatically
until it starts. If the battery in the
keyless access transmitter is
weak, the DIC displays FOB
BATTERY LOW. You can still
drive the vehicle.
See “Battery Replacement”
under Remote Keyless Entry
(RKE) System Operation on
page 2‑3 for more information.
If the fob battery is dead, you
need to insert the fob into
the fob slot to enable engine
starting. See “NO FOBS
DETECTED” underKey and
Lock Messages on page 5‑42.
3. Do not race the engine immediately after starting it.
Operate the engine and
transmission gently until the
oil warms up and lubricates
all moving parts. 4. If the engine does not start and
no DIC message is displayed,
wait 15 seconds before trying
again to let the cranking motor
cool down.
If the engine does not start after
5-10 seconds, especially in very
cold weather (below −18°C
or 0°F), it could be flooded with
too much gasoline. Try pushing
the accelerator pedal all the way
to the floor while cranking for up
to 15 seconds maximum. Wait at
least 15 seconds between each
try, to allow the cranking motor
to cool down. When the engine
starts, let go of the accelerator.
If the vehicle starts briefly but
then stops again, repeat these
steps. This clears the extra
gasoline from the engine.

Driving and Operating 9-23
Notice:Cranking the engine for
long periods of time, by pressing
the START button immediately
after cranking has ended, can
overheat and damage the
cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
The vehicle has a
Computer-Controlled
Cranking System. This feature
assists in starting the engine
and protects components.
Once cranking has been initiated,
the engine continues cranking
for a few seconds or until the vehicle
starts. If the engine does not start,
cranking automatically stops after
15 seconds to prevent cranking
motor damage. To prevent gear
damage, this system also prevents
cranking if the engine is already
running. Notice:
The engine is designed
to work with the electronics in
the vehicle. If electrical parts
or accessories are added, you
could change the way the engine
operates. Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.
Stopping the Engine
If the vehicle has an automatic
transmission, move the shift lever
to P (Park) and press and hold the
Acc. (Off/Accessory) button, located
on the instrument panel, until the
engine shuts off. If the shift lever
is not in P (Park), the engine shuts off and the vehicle goes into the
Accessory Mode. The DIC displays
SHIFT TO PARK. Once the shifter is
moved to P (Park), the vehicle turns
off. If the vehicle has a manual
transmission, it is recommended
that you move the shift lever to
R (Reverse) and set the parking
brake after you turn off the engine
by pressing and holding the Acc.
(Off/Accessory) button.
If the keyless access transmitter is
not detected inside the vehicle when
it is turned to off, the DIC displays
NO FOB
–OFF OR RUN?.
See Key and Lock Messages on
page 5‑42 for more information.

Driving and Operating 9-25
If you have to leave the vehicle
with the engine running, be sure
the vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you have moved
the shift lever into P (Park), hold
down the regular brake pedal. See if
you can move the shift lever away
from P (Park) without first pushing
the button on the lever. If you can,
it means that the shift lever was not
fully locked into P (Park).Torque Lock (Automatic
Transmission)
If you are parking on a hill and
you do not shift the transmission
into P (Park) properly, the weight
of the vehicle may put too much
force on the parking pawl in the
transmission. You may find it
difficult to pull the shift lever out of
P (Park). This is called“torque lock.”
To prevent torque lock, set the
parking brake and then shift into
P (Park) properly before you leave
the driver seat. To find out how, see
“Shifting Into P (Park)” previously in
this section.
When you are ready to drive, move
the shift lever out of P (Park) before
you release the parking brake. If torque lock does occur, you may
need to have another vehicle push
yours a little uphill to take some of
the pressure from the transmission
parking pawl, so you can pull the
shift lever out of P (Park).
Shifting Out of Park
Shift lock release prevents shifting
out of P (Park) unless the vehicle is
running or in Accessory mode and
the brake pedal is applied.
The shift lock release is always
functional except in the case of an
uncharged or low voltage (less than
9‐volt) battery. See
Jump Starting
on page 10‑82 for more information.
