1994 BUICK PARK AVENUE check engine

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
service, have it done before starting out.
Of course,
you’ll find experienced and able service experts in
Buick 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
inj ured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
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 rearview 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.
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.

0 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.
0 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 long hill.
0
0
0
0
Know how to go uphill. Shift down to “D” (Drive).
This will help cool your engine and transaxle, and
you can climb the hill better.
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 the top of a hill, be alert. There could
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.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a
different turn signal flasher and extra wiring. The green
arrows on your instrument panel
will flash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lights
will also flash, telling other drivers
you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows on your
instrument panel will flash for turns even
if the bulbs on
the trailer are burned out. Thus, you may
think drivers
behind you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Your vehicle has bulb warning lights. When you plug
trailer lights into your vehicle’s lighting system, its bulb
warning lights may not
let you know if one of your
lights goes out.
So, when you have trailer lights plugged
in, be sure to check your vehicle and trailer lights from
time to time to be sure they’re all working. Once you
disconnect the trailer lights, the bulb warning lights
again can tell you
if one of your vehicle lights is out.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift down,
you might have to use your brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, shift down to “D or 3” (Drive)
and reduce your speed to around
45 mph (70 km/h) to
reduce the possibility of engine and transaxle
overheating.
Parking on Hills
You really should not park your vehicle, with a trailer
attached,
on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But
if you ever have to park your rig on a hill, here’s
how
to do it:
1. Apply your regular brakes, but don’t shift into “P”
(Park) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
brake, and the shift to
“P” (Park).
5. Release the regular brakes.

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;
0 Shift into a gear; and
0 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 adjustment.
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.

Before you connect the cables, here are some basic
things
you should know. Positive (+) will go to
positive
(+) and negative (-) will go to negative (-)
or a metal engine part. Don’t connect (+) to (-) or
you’ll get a short that would damage the battery and
maybe other parts, too.
5. Check that the jumper cables don’t have loose or
missing insulation.
If they do, you could get a shock
and the vehicles could be damaged.

If the coolant inside the coolant recovery tank is boiling,
don’t do anything else
until it cools down.
P
The coolant level should be at or above “FULL COLD.”
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump or somewhere else in
the cooling system.
I NOTICE:
I
Engine damage from running your engine
without coolant isn’t covered
by your warranty.
If there seems to be no leak, check to see if the electric
engine fans are running.
If the engine is overheating,
both
fans should be running. If they aren’t, your vehicle
needs service.
