Rear Window Defogger
The rear window has lines that warm the glass. For best
results, clear the window of as much snow or ice as
possible before using the rear window defogger.
To turn on the rear window
defogger, find the switch
marked REAR with the
defog symbol on the lower
right corner of your climate
control system.
Press the switch
until the light in the switch comes on,
then release it. It will only work if the ignition switch is
turned
to RUN.
The rear window defogger will stay on for five to seven
minutes. then turn off.
If you need additional warming
time,
turn it on again. You can turn the defogger off at
any time by pressing the switch.
Do not attach
a temporary vehicle license, tape or decals
across the defogger grid
on the rear window.
NOTICE:
Don’t use a razor blade or something else sharp
on the inside
of’ the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn’t be covered by your warranty.

Theft-Deterrent Feature
THEFTLOCK@ is designed to discourage theft of your
radio.
It works by using a secret code to disable all radio
functions whenever battery power is removed.
The THEFTLOCK feature for the radio may be used or
ignored.
If ignored, the system plays normally and the
radio is not protected by the feature. If THEFTLOCK is
activated, your radio will
not operate if stolen.
When THEFTLOCK
is activated, the radio will display
LOC to indicate
a locked condition anytime battery
power
is removed. If your battery loses power for any
reason, you must unlock
the radio with the secret code
before
it will operate.

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. Your brakes may not have time to cool
between hard stops. Your brakes
will wear out much
faster
if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking. That
means better braking and longer brake life.
If your engine ever stops while you’re driving, brake
nol-mally but don’t
pump your brakes. If you do, the
pedal
may get harder to push down. If your 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 may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent
a braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You may
hear
a momentary motor or clicking noise while this test
is going on. This is normal.
If there’s a problem with the
anti-lock brake system, this
warning light
will stay on.
See “Anti-Lock Brake
System Warning Light‘‘ in
the Index.

Here’s how anti-lock works. Let’s say the road is wet.
You’re driving safely. Suddenly an animal jumps out in
front
of you. The anti-lock system
can change the brake pressure
faster than
any driver could. The computer is
programmed to make the most of available tire and
road conditions.
You slam on the brakes. Here’s 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.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.

Remember: Anti-lock doesn’t change the time you need
to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in
front
of you, you won’t have time to apply your brakes
if that vehicle suddenly slows
or stops. Always leave
enough room up ahead to stop, even though you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down firmly and let anti-lock work for you. You may feel the
brakes vibrate, or you may notice some noise, but this
is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more than even
the very best braking.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s 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’s no traction, inertia will keep
the vehicle going in the same direction. If you’ve ever
tried to steer a vehicle on wet ice, you’ll understand this.
