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.

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
boosts 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 your radio.
FM Stereo
FM stereo gives the best sound, but FM signals
only reach about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals,
causing the sound to fade in and out.
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 could cause
loss of the XM™ signal for a period of time.
The radio might display NO XM SIGNAL to
indicate interference.
Care of Your CDs and DVDs
Handle CDs carefully. Store them in their original
cases or other protective cases and away from
direct sunlight and dust. The CD player scans the
bottom surface of the disc. If the surface of a
CD is damaged, such as cracked, broken,
or scratched, the CD does not play properly or not
at all. If the surface of a CD is soiled, take a
soft, lint free cloth or dampen a clean, soft cloth in
a mild, neutral detergent solution mixed with
water, and clean it. Make sure the wiping process
starts from the center to the edge.
Do not touch the bottom side of a CD while
handling it; this could damage the surface. Pick up
CDs by grasping the outer edges or the edge of
the hole and the outer edge.

Care of the CD and DVD Player
The use of CD lens cleaners for CDs is not
advised, due to the risk of contaminating the lens
of the CD optics with lubricants internal to the
CD mechanism.
Fixed Mast Antenna
The xed mast antenna can withstand most car
washes without being damaged. If the mast should
ever become slightly bent, straighten it out by
hand. If the mast is badly bent, replace it.
Check occasionally to make sure the mast is
still tightened to its base. If tightening is
required, tighten by hand, then with a wrench
one quarter turn.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on
the roof of your vehicle. Keep this antenna clear of
snow and ice build up for clear radio reception.
A vehicle with a sunroof might not get the
best performance from the XM™ system if the
sunroof is open.
Loading items onto the roof of your vehicle can
interfere with the performance of the XM™ system.
Make sure the XM™ Satellite Radio antenna is
not obstructed.

Notice:If the other vehicle’s system is not a
12-volt system with a negative ground,
both vehicles can be damaged. Only use
vehicles with 12-volt systems with negative
grounds to jump start your vehicle.
2. If you have a vehicle with a diesel engine with
two batteries, you should know before you
begin that, especially in cold weather, you may
not be able to get enough power from a
single battery in another vehicle to start your
diesel engine. If your vehicle has more
than one battery, use the battery that is closer
to the starter — this will reduce electrical
resistance. This is located on the passenger
side, in the rear of the engine compartment.
3. Get the vehicles close enough so the jumper
cables can reach, but be sure the vehicles are
not touching each other. If they are, it could
cause an unwanted ground connection.
You would not be able to start your vehicle,
and the bad grounding could damage the
electrical systems.To avoid the possibility of the vehicles rolling,
set the parking brake rmly on both vehicles
involved in the jump start procedure. Put
the automatic transmission in PARK (P) or a
manual transmission in NEUTRAL before
setting the parking brake. If you have a
four-wheel-drive vehicle, be sure the transfer
case is in a drive gear, not in NEUTRAL.
Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty.
Always turn off your radio and other
accessories when jump starting your vehicle.
4. Turn off the ignition on both vehicles.
Unplug unnecessary accessories plugged into
the cigarette lighter or the accessory power
outlets. Turn off the radio and all the
lamps that are not needed. This will avoid
sparks and help save both batteries. And it
could save the radio!

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire pressure
levels. If your vehicle has this feature, sensors
are mounted on each tire and wheel assembly,
except the spare tire. The TPMS sensors monitor
the air pressure in your vehicle’s tires and
transmit tire pressure readings to a receiver
located in the vehicle.
The TPMS is designed to alert the driver, if a low
tire pressure condition exists. If your vehicle has the
Driver Information Center (DIC), the driver may also
check tire pressure levels using the DIC.
When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol located on the instrument panel
cluster. If your vehicle has the DIC feature, a
message to check the pressure in a speci c tire
will also appear on the DIC display. The low
tire pressure warning symbol on the instrument
panel cluster and the CHECK TIRE PRESSURE
warning message on the DIC display will appear at
each ignition cycle until the tires are in ated to
the correct in ation pressure.For additional information and details about the
DIC operation and displays seeDIC Operation and
Displays (With DIC Buttons) on page 268orDIC
Operation and Displays (Without DIC Buttons)
on page 275andDIC Warnings and Messages on
page 279.
You may notice, during cooler weather conditions,
that the tire pressure monitor light, located on
the instrument panel cluster, and the CHECK TIRE
PRESSURE message will appear when the
vehicle is rst started and then turn off as you
start to drive the vehicle. This could be an early
indicator that the tire pressures are getting low and
need to be in ated to the proper pressure.
Each tire, including the spare (if provided), should
be checked monthly when cold and in ated to
the in ation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
in ation pressure label. (If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire in ation pressure label, you
should determine the proper tire in ation
pressure for those tires.)

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your
tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels.
SeeWhen It Is Time for New Tires on page 568
andWheel Replacement on page 573for
more information.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, use the wheel wrench/hoist shaft to tighten
the cable. SeeChanging a Flat Tire on page 576.
If your vehicle has dual rear wheels, also see
Dual Tire Operation on page 560.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance (Gasoline Engine) on page 623.
