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. 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.
Notice:The chime signals related to safety belts,
parking brake, and other functions of your vehicle
operate through the radio/entertainment system.
If that equipment is replaced or additional equipment
is added to your vehicle, the chimes may not
work. Make sure that replacement or additional
equipment is compatible with your vehicle before
installing it. SeeAccessories and Modifications
on page 5-3.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be

Anti-Lock Brake System (ABS)

help prevent a braking skid.
If your vehicle has ABS,
this warning light on the
instrument panel
cluster will come on brie y

vehicle.
When you start your engine, or when you begin to drive
away, ABS will check itself. You may hear a momentary
motor or clicking noise while this test is going on,
and you may even notice that your brake pedal moves
or pulses a little. This is normal.Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down.
If one of the wheels is about to stop rolling, the computer
will separately work the brakes at each front wheel
and at both rear wheels.
