Understanding Radio Reception
FM Stereo
FM stereo will give you the best sound. But FM signals
will reach only about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to come and
go.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere
with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble
to reduce this noise if you ever get it.

Downloaded from www.Manualslib.com manuals search engine 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
normally 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
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

Downloaded from www.Manualslib.com manuals search engine 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.
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.
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 the
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.
4-7

Downloaded from www.Manualslib.com manuals search engine 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 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
Use your anti-lock braking system when you need to.
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.

An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended
9 and 3 o’clock positions, you can
turn it a full
180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and
just as quickly straighten the wheel once you have
avoided the object.
The fact that such emergency situations are always
possible is
a good reason to practice defensive driving at
all times and wear safety belts properly. You
may find sometime that your right wheels have
dropped off the edge of a road onto the shoulder while
you’re driving.
OFF-ROAD RECOVERY
/
w rY// edge of pawed surface
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator and then, if there is nothing in the way, steer
so that your vehicle straddles the edge of the pavement.
You can turn the steering wheel up to one-quarter turn
until the right front tire contacts the pavement edge. Then
turn your steering wheel to go straight down the roadway.
~ 4-10

Downloaded from www.Manualslib.com manuals search engine If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer
the way you want the
vehicle to go.
If you start steering quickly enough, your
vehicle may straighten
out. Always be ready for a
second skid if it occurs.
Of course, traction
is reduced when water, snow, ice,
gravel or other material is
on the road. For safety, you’ll
want
to slow down and adjust your driving to these
conditions. It is important
to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on
a surface with reduced traction, try
your best to avoid sudden steering, acceleration or
braking (including engine braking by shifting
to a
lower gear). Any sudden changes could cause the tires
to slide. You may not realize the surface is slippery
until your vehicle is skidding. Learn to recognize
warning clues
-- such as enough water, ice or packed
snow on the road to make a “mirrored surface”
-- and
slow down when
you have any doubt.
Remember: Any anti-lock brake system (ABS) helps
avoid
only the braking skid.
Driving at Night
Night driving is more dangerous than day driving.
One reason is
that some drivers are likely to be
impaired
-- by alcohol or drugs, with night vision
problems, or by fatigue.

Accelerate gently. Try not to break the fragile traction. If
you accelerate too fast, the drive wheels will spin and

’, Your anti-lock brakes improve your vehicle’s stability

though
you have an anti-lock braking system, you’ll % want to begin stopping sooner than you would on dry
e pavement. See “Anti-Lock” in the Index.

,’ Allow greater following distance on any slippery road.

’: until you hit a spot that’s covered with ice. On an

shaded areas where the sun can’t reach: around
clumps
of trees, behind buildings or under bridges.
Sometimes the surface of a curve or an overpass may

remain icy when the surrounding roads are clear. If
you see a patch
of ice ahead of you, brake before you
are on it.
Try not to brake while you’re actually on
the ice, and avoid sudden steering maneuvers, If you
are stopped by heavy snow, you could be in a
serious situation. You should probably stay with your
vehicle unless you know for sure that you are near help
and you can hike through the snow. Here are some
things
to do to summon help and keep yourself and your
passengers safe:
0 Turn on your hazard flashers.

Downloaded from www.Manualslib.com manuals search engine 0 Tie a red cloth to your vehicle to alert police that
you’ve been stopped
by the snow.
0 Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags,
floor
mats -- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
I A CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can’t see it or smell it,
so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open a window just a little on the side of the
vehicle that’s away from the wind. This will help
keep CO out.
