{CAUTION:
This system provides you with a far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and
you or others can be injured or killed.
Always keep your eyes on the road and
your mind on the drive — avoid engaging
in extended searching while driving.
Keeping your mind on the drive is important for
safe driving. Here are some ways in which you can
help avoid distraction while driving.
While your vehicle is parked:
Familiarize yourself with all of its controls.
Familiarize yourself with its operation.
Set up your audio system by presetting your
favorite radio stations, setting the tone, and
adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite
radio stations using the presets and steering
wheel controls if the vehicle has them.Notice:Before adding any sound equipment
to your vehicle, such as an audio system,
CD player, CB radio, mobile telephone,
or two-way radio, make sure that it can be
added by checking with your dealer/retailer.
Also, check federal rules covering mobile radio
and telephone units. If sound equipment can
be added, it is very important to do it properly.
Added sound equipment may interfere with
the operation of your vehicle’s engine, radio,
or other systems, and even damage them.
Your vehicle’s systems may interfere with
the operation of sound equipment that
has been added.
Your vehicle has a feature called Retained
Accessory Power (RAP). With RAP, the audio
system can be played even after the ignition
is turned off. SeeRetained Accessory Power
(RAP) on page 115for more information.

Steering
Electric Power Steering
If the engine stalls while you are driving, the
power steering assist system will continue
to operate until you are able to stop your vehicle.
If you lose power steering assist because the
electric power steering system is not functioning,
you can steer, but it will take more effort.
If you turn the steering wheel in either direction
several times until it stops, or hold the steering
wheel in the stopped position for an extended
amount of time, you may notice a reduced amount
of power steering assist. The normal amount of
power steering assist should return shortly after a
few normal steering movements.
The electric power steering system does not
require regular maintenance. If you suspect
steering system problems and/or the POWER
STEERING message comes on, contact your
dealer/retailer for service repairs. SeeDIC
Warnings and Messages on page 184.
Steering Tips
It is important to take curves at a reasonable
speed.
A lot of the “driver lost control” accidents mentioned
on the news happen on curves. Here is why:
Experienced driver or beginner, each of us is
subject to the same laws of physics when driving
on curves. The traction of the tires against the
road surface makes it possible for the vehicle to
change its path when you turn the front wheels.
If there is no traction, inertia will keep the
vehicle going in the same direction. If you have
ever tried to steer a vehicle on wet ice, you
will understand this.
The traction you can get in a curve depends on
the condition of the tires and the road surface,
the angle at which the curve is banked, and your
speed. While you are in a curve, speed is the
one factor you can control.

Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the
tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combined
weight of optional accessories. Some examples of
optional accessories are, automatic transmission,
power steering, power brakes, power windows,
power seats, and air conditioning.
Aspect Ratio:The relationship of a tire’s height
to its width.
Belt:A rubber coated layer of cords that is
located between the plies and the tread. Cords
may be made from steel or other reinforcing
materials.
Bead:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread.Cold Tire Pressure:The amount of air pressure
in a tire, measured in pounds per square inch (psi)
or kilopascals (kPa) before a tire has built up heat
from driving. SeeInation - Tire Pressure on
page 347.
Curb Weight:This means the weight of a motor
vehicle with standard and optional equipment
including the maximum capacity of fuel, oil, and
coolant, but without passengers and cargo.
DOT Markings:A code molded into the sidewall
of a tire signifying that the tire is in compliance
with the U.S. Department of Transportation (DOT)
motor vehicle safety standards. The DOT code
includes the Tire Identication Number (TIN),
an alphanumeric designator which can also identify
the tire manufacturer, production plant, brand,
and date of production.
GVWR:Gross Vehicle Weight Rating.
SeeLoading Your Vehicle on page 259.
GAWR FRT:Gross Axle Weight Rating for the
front axle. SeeLoading Your Vehicle on page 259.
GAWR RR:Gross Axle Weight Rating for the
rear axle. SeeLoading Your Vehicle on page 259.

Maintenance Footnotes
(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, chang, etc.
Inspect disc brake pads for wear and rotors for
surface condition. Inspect drum brake linings/shoes
for wear or cracks. Inspect other brake parts,
including drums, wheel cylinders, calipers,
parking brake, etc.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing
parts or signs of wear. Inspect power steering
cables for proper hook-up, binding, cracks,
chang, etc.
(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings and clamps; replace
with genuine parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside
of the radiator and air conditioning condenser is
recommended at least once a year.(d)Inspect wiper blades for wear, cracking,
or contamination. Clean the windshield and wiper
blades, if contaminated. Replace wiper blades
that are worn or damaged. See Windshield Wiper
Blade Replacement on page 337andWindshield
and Wiper Blades on page 378for more
information.
(e)Make sure the safety belt reminder light and all
your belts, buckles, latch plates, retractors, and
anchorages are working properly. Look for
any other loose or damaged safety belt system
parts. If you see anything that might keep a safety
belt system from doing its job, have it repaired.
Have any torn or frayed safety belts replaced.
Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular
maintenance.
(f)Lubricate all key lock cylinders, door hinges
and latches, hood hinges and latches, and trunk lid
hinges and latches. More frequent lubrication
may be required when exposed to a corrosive
environment. Applying silicone grease on
weatherstrips with a clean cloth will make them
last longer, seal better, and not stick or squeak.
