Audio System(s) Setting the Time
Notice: Before you add any sound equipment to
your vehicle
- like a tape player, CB radio, mobile
telephone or two-way radio
- be sure you can
add what you want.
If you can, it’s very important
to do
it properly. Added sound equipment may
interfere with the operation of your vehicle’s engine,
Delphi Electronics radio or other systems, and
even damage them. Your vehicle’s systems may
interfere with the operation of sound equipment that
has been added improperly.
So, before adding sound equipment, check with
your dealer and be sure to check federal rules
covering mobile radio and telephone units.
Your audio system has been designed to operate easily
and to give years
of listening pleasure. You will get the
most enjoyment out of it
if you acquaint yourself with it
first. Find out what your audio system can do and how to
most out
of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is turned
off. See
“Retained Accessory Power
(RAP)” under !,nr?it.ior!

Your radio may have a button marked with an H or
HR to represent hours and an
M or MIN to represent
minutes.
Press and hold the hour button until the correct hour
appears on the display. AM will also appear for morning
hours. Press and hold the minute button until the
correct minute appears on the display. The time may be
set with the ignition on or
off.
To synchronize the time with an FM station broadcasting
Radio Data System (RDS) information, press and
hold the hour and minute buttons at the same time until
UPDATED appears on the display.
If the time is not
available from the station,
NO UPDAT will appear on the
display instead.

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 Brake System (ABS)
Your vehicle may have anti-lock brakes. ABS is an
advanced electronic braking system that will help prevent a braking skid.
If your vehicle has anti-lock
brakes, this warning light
on the instrument panel will
come on briefly when
you start your vehicle.
When you start your engine, or when you 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, and you may even
notice that your brake pedal moves or pulses a little.
This is normal.

When you want to leave the freeway, move to the
proper lane well in advance.
If you miss your exit,
do not, under any circumstances, stop and back up.
Drive on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are
going slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
- such as after a day’s
work
- don’t plan to make too many miles that first
part of the journey. Wear comfortable clothing and shoes
you can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go. If it needs
you’ll find experienced and able service experts in
dealerships all across North America. They’ll be ready
and willing to help
if you need it.

Highway Hypnosis
Is there actually such a condition as “highway hypnosis”?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on
the road, the drone of the engine, and the rush of
the wind against the vehicle that can make you sleepy.
Don’t let
it happen to you! If it does, your vehicle can
leave the road in
less than a second, and you could
crash and be injured.
What can you do about highway hypnosis?
First, be aware that it can happen.
Then here are some tips:
e
e
e
Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and
to the sides. Check your mirrors and your
instruments frequently.
If you get sleepy, pull
off the road into a rest,
service or parking area and take a nap, get some
exercise, or both. For safety, treat drowsiness
on the highway as an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.
4-24

If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transaxle. These parts can work hard on
mountain roads.
Know how to go down hills. The most important
thing to know is this: let your engine do some
of
the slowing down. Shift to a lower gear when you go
down a steep or Ion-
511.
If you don’t shift down, your brakes could get
so hot that they wouldn’t work well. You would
then have poor braking or even none going
down
a hill. You could crash. Shift down to let
your engine assist your brakes on
a steep
downhill slope. Coast
...d downhill in NEUTRA- ,.., or with the
ignition
off is dangerous. Your brakes will have
to do
all the work of slowing down. They could
get
so hot that they wouldn’t work well. You
would then have poor braking or even none going down
a hill. You could crash. Always
have your engine running and your vehicle in
gear when you go downhill.
0 Know how to go uphill. You may want to shift down to
a lower gear. The lower gears help cool your engine
and transaxle, and you can climb the hill better.
e Stay in your own lane when driving on two-lane
roads in hills or mountains. Don’t swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.
- As you go over ihe iop oi a hiii, be aieri. There couia
be something in your lane, like a stalled car or an
accident.
You may see highway signs on mountains that warn
of special problems. Examples are long grades,
passing
or no-passing zones, a falling rocks area or
winding roads. Be alert to these and take appropriate
action.
4-25

Here are some things to do to summon help and keep
yourself and your passengers safe:
e Turn on your hazard flashers.
Tie a red cloth to your vehicle to alert police that
you’ve been stopped by the snow.
e 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.
Snow can trap exhaust gases un,,r 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.

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
start your engine,
* shift into a gear, and
* release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine
oil, belts, cooling system and brake system.
Each of these is covered in this manual, and the
Index will help you find them quickly.
If you’re trailering,
it’s a good idea to review these sections before you
start your trip.
Check periodically
to see that all hitch nuts and bolts
are tight.
Trailer Wiring Harness
Your vehicle has a trailer wiring harness located at the
rear of your vehicle.
To use the trailer wiring harness
you need a converter kit. Contact your dealer for more
information.
