CD is in the player. Press this button again and
the system automatically searches for an auxiliary input
device, such as a portable audio player. If a portable
audio player is not connected, No Aux Input Device
Found may display.
Care of CDsIf playing a CD-R, the sound quality can be reduced due
to CD-R quality, the method of recording, the quality of
the music that has been recorded, and the way the CD-R
has been handled. Handle them carefully. Store CD-R(s)
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. 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.

BrakingSeeBrake System Warning Light on page 4-27.
Braking action involves perception time and reaction
time. Deciding to push the brake pedal is perception
time. Actually doing it 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 100 km/h (60 mph) travels 20 m
(66 feet). That could be a lot of distance in an emergency,
so keeping enough space between the 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 with a lot of heavy braking. Keeping pace with the
traffic and allowing realistic following distances
eliminates a lot of unnecessary braking. That means
better braking and longer brake life.
If the engine ever stops while the vehicle is being driven,
brake normally but do not pump the brakes. If the brakes
are pumped, the pedal could get harder to push down.
If the engine stops, there will still be some power brake
assist but it will be used when the brake is applied. 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
vehicle performance. SeeAccessories and Modifications
on page 6-3.

Antilock Brake System (ABS)The vehicle might have the Antilock Brake System
(ABS), an advanced electronic braking system that helps
prevent a braking skid.
If the vehicle has ABS, this
warning light on the
instrument panel cluster
comes on briefly when the
vehicle is started.
When the engine is started, or when the vehicle begins
to drive away, ABS checks itself. A momentary motor
or clicking noise might be heard while this test is going
on, and it might even be noticed that the 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 the 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.
ABS can change the brake pressure to each wheel, as
required, faster than any driver could. This can help
the driver steer around the obstacle while braking hard.
As the brakes are applied, the computer keeps
receiving updates on wheel speed and controls braking
pressure accordingly.
Remember: ABS does not change the time needed to
get a foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, there will not be enough time to apply
the brakes if that vehicle suddenly slows or stops.
Always leave enough room up ahead to stop, even
with ABS.
