Radio Reception
Frequency interference and static can occur duringnormal radio reception if items such as cell phonechargers, vehicle convenience accessories, and externalelectronic devices are plugged into the accessorypower outlet. If there is interference or static, unplug theitem 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 stationfrequencies to interfere with each other. For better radioreception, most AM radio stations boost the power levelsduring the day, and then reduce these levels during thenight. Static can also occur when things like storms andpower lines interfere with radio reception. When thishappens, try reducing the treble on the radio.
FM Stereo
FM signals only reach about 10 to 40 miles(16 to 65 km). Although the radio has a built-in electroniccircuit that automatically works to reduce interference,some static can occur, especially around tall buildings orhills, causing the sound to fade in and out.
XM™ Satellite Radio Service
XM Satellite Radio Service gives digital radio receptionfrom coast-to-coast in the 48 contiguous United States,and in Canada. Just as with FM, tall buildings or hills caninterfere with satellite radio signals, causing the sound tofade in and out. In addition, traveling or standing underheavy foliage, bridges, garages, or tunnels may causeloss of the XM signal for a period of time.
Cellular Phone Usage
Cellular phone usage may cause interference with thevehicle’s radio. This interference may occur whenmaking or receiving phone calls, charging the phone’sbattery, or simply having the phone on. This interferencecauses an increased level of static while listening tothe radio. If static is received while listening to the radio,unplug the cellular phone and turn it off.

Repeat this until help arrives but only when you feelreally uncomfortable from the cold. Moving aboutto keep warm also helps.
If it takes some time for help to arrive, now and thenwhen you run the engine, push the acceleratorpedal slightly so the engine runs faster than the idlespeed. This keeps the battery charged to restartthe vehicle and to signal for help with the headlamps.Do this as little as possible to save fuel.
If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
Slowly and cautiously spin the wheels to free thevehicle when stuck in sand, mud, ice, or snow. SeeRocking Your Vehicle to Get It Out on page 5-17.
If the vehicle has a traction system, it can often help tofree a stuck vehicle. Refer to the vehicle’s tractionsystem in the Index. If stuck too severely for the tractionsystem to free the vehicle, turn the traction system offand 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,seeTire Chains on page 6-70.
Rocking Your Vehicle to Get It Out
Turn the steering wheel left and right to clear the areaaround the front wheels. Turn off any traction or stabilitysystem. Shift back and forth between R (Reverse) and aforward gear, spinning the wheels as little as possible.To prevent transmission wear, wait until the wheels stopspinning before shifting gears. Release the acceleratorpedal while shifting, and press lightly on the acceleratorpedal when the transmission is in gear. Slowly spinningthe wheels in the forward and reverse directions causes arocking motion that could free the vehicle. If that does notget the vehicle out after a few tries, it might need to betowed out. If the vehicle does need to be towed out, seeTowing Your Vehicle on page 5-24.

Properly torqued wheel nuts are necessary to helpprevent brake pulsation. When tires are rotated, inspectbrake pads for wear and evenly tighten wheel nuts inthe proper sequence to torque specifications inCapacities and Specifications on page 6-109.
Brake linings should always be replaced as completeaxle sets.
Brake Pedal Travel
See your dealer/retailer if the brake pedal does notreturn to normal height, or if there is a rapid increase inpedal travel. This could be a sign that brake servicemight be required.
Brake Adjustment
Every time the brakes are applied, with or without thevehicle moving, the brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its manyparts have to be of top quality and work well together ifthe vehicle is to have really good braking. The vehiclewas designed and tested with top-quality brake parts.When parts of the braking system are replaced — forexample, when the brake linings wear down and newones are installed — be sure to get new approvedreplacement parts. If this is not done, the brakes mightnot work properly.
For example, if someone puts in brake linings that arewrong for the vehicle, the balance between the front andrear brakes can change — for the worse. The brakingperformance expected can change in many other ways ifthe wrong replacement brake parts are installed.
Battery
Refer to the replacement number on the original batterylabel when a new battery is needed.
