channels available for the selected
category.
XM Radio ID: If tuned to channel 0,
this message alternates with the
XM Radio 8 digit radio ID label.
This label is needed to activate
the service.
Unknown: If this message is
received when tuned to channel 0,
there could be a receiver fault.
Consult with your dealer/retailer.
Check Antenna: If this message
does not clear within a short period
of time, the receiver could have a
fault. Consult with your dealer/
retailer.
XM Not Available: If this message
does not clear within a short period
of time, the receiver could have a
fault. Consult with your dealer/
retailer.Radio Reception
Frequency interference and static
can occur during normal radio
reception if items such as cell phone
chargers, vehicle convenience
accessories, and external electronic
devices are plugged into the
accessory power outlet. If there is
interference or static, unplug the
item from the accessory power
outlet.
FM
FM signals only reach about
16 to 65 km (10 to 40 miles).
Although the radio has a built-in
electronic circuit that automatically
works to reduce interference, some
static can occur, especially around
tall buildings or hills, causing the
sound to fade in and out.
AM
The range for most AM stations is
greater than for FM, especially at
night. The longer range can cause
station frequencies to interfere with
each other. For better radio
reception, most AM radio stations
boost the power levels during the
day, and then reduce these levels
during the night. Static can also
occur when things like storms and
power lines interfere with radio
reception. When this happens, try
reducing the treble on the radio.
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.

Infotainment System 6-19
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 can cause 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.
Backglass Antenna
The AM-FM antenna is integrated
with the rear window defogger,
located in the rear window. Make
sure that the inside surface of the
rear window is not scratched and
that the lines on the glass are not
damaged. If the inside surface isdamaged, it could interfere with
radio reception. For proper radio
reception, the antenna connector
needs to be properly attached to
the post on the glass.
If a cellular telephone antenna
needs to be attached to the glass,
make sure that the grid lines for the
AM-FM antenna are not damaged.
There is enough space between the
grid lines to attach a cellular
telephone antenna without
interfering with radio reception.
Notice:
Using a razor blade or
sharp object to clear the inside
rear window can damage the rear
window antenna and/or the rear
window defogger. Repairs would
not be covered by the vehicle
warranty. Do not clear the inside
rear window with sharp objects. Notice:
Do not apply aftermarket
glass tinting with metallic film.
The metallic film in some tinting
materials will interfere with or
distort the incoming radio
reception. Any damage caused to
your backglass antenna due to
metallic tinting materials will not
be covered by the vehicle
warranty.
Satellite Radio Antenna
For vehicles with XM™ satellite
radio service, the antenna is located
on the roof of the vehicle. Keep the
antenna clear of obstructions for
clear radio reception.

Driving and Operating 8-5
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,
the pedal could get harder to push
down. If the engine stops, there will
still be some power brake assist but
it will be used when the brake is
applied. Once the power assist is
used up, it can take longer to stop
and the brake pedal will be harder
to push.
Adding non-dealer/non-retailer
accessories can affect vehicle
performance. SeeAccessories and
Modifications on page 9‑3.
Steering
Power Steering
If power steering assist is lost
because the engine stops or the
power steering system is not
functioning, the vehicle can be
steered but it will take more effort.
Speed Variable Assist Steering
The vehicle has a steering system
that varies the amount of effort
required to steer the vehicle in
relation to the speed of the vehicle.
The amount of steering effort
required is less at slower speeds to
make the vehicle more
maneuverable and easier to park. At
faster speeds, the steering effort
increases to provide a sport-like feel
to the steering. This provides
maximum control and stability.
If the vehicle seems harder to steer
than normal when parking or driving
slowly, there may be a problem with
the system. You will still have power
steering, but steering will be stiffer
than normal at slow speeds. See
your dealer/retailer for service.
Steering Tips
It is important to take curves at a
reasonable speed.
Traction in a curve depends on the
condition of the tires and the road
surface, the angle at which the
curve is banked, and vehicle speed.
While in a curve, speed is the one
factor that can be controlled.
If there is a need to reduce speed,
do it before entering the curve, while
the front wheels are straight.
Try to adjust the speed so you can
drive through the curve. Maintain a
reasonable, steady speed. Wait to
accelerate until out of the curve, and
then accelerate gently into the
straightaway.

Driving and Operating 8-9
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Going down steep or long hills,
shift to a lower gear.
{WARNING
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.
{WARNING
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will have
to do all the work of slowing down
and they 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. Always have the
engine running and the vehicle in
gear when going downhill.
.Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
.Top of hills: Be
alert—something could be in
your lane (stalled car, accident).
.Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip.
Wet ice can occur at about 0°C
(32°F) when freezing rain begins to
fall, resulting in even less traction.
Avoid driving on wet ice or in
freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction.
Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.

8-18 Driving and Operating
Ignition Positions (Key
Access)
The ignition switch has four different
positions.
Notice:Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct
key, make sure it is all the way in,
and turn it only with your hand.
If the key cannot be turned by
hand, see your dealer/retailer. To shift out of P (Park), turn the
ignition to ON/RUN and apply the
brake pedal.
A (LOCK/OFF):
This is the only
position from which the key can be
removed. This locks the ignition and
automatic transmission.
The shift lever must be in P (Park)
to turn the ignition switch to the
LOCK/OFF position.
The ignition switch can bind in the
LOCK/OFF position with the wheels
turned off center. If this happens,
move the steering wheel from right
to left while turning the key to ACC/
ACCESSORY. If this does not work,
then the vehicle needs service.
B (ACC/ACCESSORY) : This
position provides power to some of
the electrical accessories. It unlocks
the ignition. The transmission is
also unlocked in this position on
automatic transmission vehicles.
To move the key from ACC/
ACCESSORY to LOCK/OFF, the
shift lever must be in P (Park). C (ON/RUN):
The ignition switch
stays in this position when the
engine is running. This position can
be used to operate the electrical
accessories, including the
ventilation fan and 12 volt power
outlet, as well as to display some
warning and indicator lights.
The battery could be drained if the
key is left in the ACC/ACCESSORY
or ON/RUN position with the engine
off. The vehicle might not restart if
the battery is allowed to drain for an
extended period of time.
D (START) : This position starts
the engine. When the engine starts,
release the key. The ignition switch
will return to ON/RUN for normal
driving.
A warning tone sounds when the
driver door is opened when the
ignition is still in ACC/ACCESSORY
and the key is in the ignition.

Driving and Operating 8-25
Shifting Out of Park
Automatic Transmission
Shift Lock
The vehicle has an electronic shift
lock release system. The shift lock
release is designed to:
.Prevent ignition key removal
unless the shift lever is in
P (Park).
.Prevent movement of the shift
lever out of P (Park), unless the
ignition is in ON/RUN and the
brake pedal is applied.
The shift lock is always functional
except in the case of a an
uncharged or low voltage (less than
9 volt) battery.
If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the
battery. See Jump Starting
on
page 9‑75. If the console shift lever cannot be
moved out of P (Park):
1. Apply and maintain the regular
brakes.
2. Turn the ignition to ON/RUN position. See Ignition Positions
(Key Access)
on page 8‑18or
Ignition Positions (Keyless
Access)
on page 8‑19for more
information.
3. Let up on the shift lever and make sure the shift lever is
pushed all the way into P (Park).
4. Press the shift lever button
5. Then, move the shift lever into the desired gear.
If you still cannot move the shift
lever from P (Park), consult your
dealer/retailer or a professional
towing service.
Parking Over Things
That Burn
{WARNING
Things that can burn could touch
hot exhaust parts under the
vehicle and ignite. Do not park
over papers, leaves, dry grass,
or other things that can burn.
