Audio System(s)
Determine which radio the vehicle has and read the
following pages to become familiar with its features.
{CAUTION:
Taking your eyes off the road for extended periods
could cause a crash resulting in injury or death to
you or others. Do not give extended attention to
entertainment tasks while driving.
This system provides access to many audio and non
audio listings.To minimize taking your eyes off the road while driving,
do the following while the vehicle is parked:
Become familiar with the operation and controls of
the audio system.
Set up the tone, speaker adjustments, and preset
radio stations.
For more information, seeDefensive Driving on page 4-2.
Notice:Contact your dealer/retailer before adding
any equipment.
Adding audio or communication equipment could
interfere with the operation of the vehicle’s engine,
radio, or other systems, and could damage them.
Follow federal rules covering mobile radio and
telephone equipment.
The vehicle has Retained Accessory Power (RAP).
With RAP, the audio system can be played even after

Your Driving, the Road, and
the Vehicle
Driving for Better Fuel Economy
Driving habits can affect fuel mileage. Here are some
driving tips to get the best fuel economy possible.
Avoid fast starts and accelerate smoothly.
Brake gradually and avoid abrupt stops.
Avoid idling the engine for long periods of time.
When road and weather conditions are appropriate,
use cruise control, if equipped.
Always follow posted speed limits or drive more
slowly when conditions require.
Keep vehicle tires properly inated.
Combine several trips into a single trip.
Replace the vehicle’s tires with the same TPC Spec
number molded into the tire’s sidewall near the size.
Follow recommended scheduled maintenance.
Defensive Driving
Defensive driving means “always expect the
unexpected.” The rst step in driving defensively is to
wear your safety belt — SeeSafety Belts: They Are for
Everyone on page 1-14.
{CAUTION:
Assume that other road users (pedestrians,
bicyclists, and other drivers) are going to be
careless and make mistakes. Anticipate what they
might do and be ready. In addition:
Allow enough following distance between you
and the driver in front of you.
Focus on the task of driving.
Driver distraction can cause collisions resulting in
injury or possible death. These simple defensive
driving techniques could save your life.
4-2

Braking
SeeBrake System Warning Light on page 3-39.
Braking action involves perception time and reaction
time. First, you have to decide to push on the brake
pedal. That is perception time. Then you have to bring
up your foot and do it. That is reaction time.
Average reaction time is about three-fourths of a second.
But that is only an average. It might be less with
one driver and as long as two or three seconds or
more with another. Age, physical condition, alertness,
coordination, and eyesight all play a part. So do alcohol,
drugs, and frustration. But even in three-fourths of a
second, a vehicle moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of distance in an
emergency, so keeping enough space between your
vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement or
gravel; the condition of the road, whether it is wet, dry, or
icy; tire tread; the condition of the brakes; the weight of
the vehicle; and the amount of brake force applied.
Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is a
mistake. The brakes might not have time to cool between
hard stops. The brakes will wear out much faster if you do
a lot of heavy braking. If you keep pace with the trafficand allow realistic following distances, you will eliminate a
lot of unnecessary braking. That means better braking
and longer brake life.
If your vehicle’s engine ever stops while you are driving,
brake normally but do not pump the brakes. If you do, the
pedal could get harder to push down. If the engine stops,
you will still have some power brake assist. But you will
use it when you brake. 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
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3.
Antilock Brake System (ABS)
Your vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that will help
prevent a braking skid.
When you start the engine and begin to drive away,
ABS will check itself. You might hear a momentary
motor or clicking noise while this test is going on, and
you might even notice that the brake pedal moves
a little. This is normal.
