check engine light BUICK PARK AVENUE 1994 Owners Manual

When the PASS-Key% system senses that someone is using the wrong key,
it shuts down the vehicle’s starter
and fuel systems. For about three minutes,
the starter
won’t work and
fuel won’t go to the engine. If someone
tries to start your vehicle again or uses another key
during this time, the vehicle will not start. This
discourages someone from randomly trying different
keys with different resistor pellets in an attempt to make
a match.
The ignition key must be clean and dry before it’s
inserted in the ignition or the engine may not start. If the
engine does not start and the “SECURITY’’ light comes
on, the key may be dirty
or wet. Turn the ignition off.
Clean and dry the key. Wait about three minutes and try
again. The security light may remain on during this
time. If
the starter still won’t work, and the key appears
to be clean and dry, wait about three minutes and try the
other ignition key. At this time, you may also want to
check the fuse (see “Fuses and Circuit Breakers”
in the
Index). If
the starter won’t work with the other key, your vehicle needs
service. If your vehicle does start, the first
ignition key may be faulty. See your Buick dealer or a
locksmith who can service the PASS-Key@II.
If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won’t work and the
“SECURITY” light
will flash. But you don’t have to
wait three minutes before trying one of the other ignition
keys.
See your Buick dealer or
a locksmith who can service
the PASS-Key@II to have a new key made.
If you’re ever driving and the “SECURITY” light comes
on and stays on,
you will be able to restart your engine if
you turn it off. Your PASS-Key% system, however, is
not working properly
and must be serviced by your
Buick dealer. Your vehicle is not protected by the
PASS-Key% system.
If you lose or damage a PASS-Key@II ignition key, see
your Buick dealer or a locksmith who can service
PASS-Key@II to have a
new key made.

the engine oil life monitor
system. The system
determines the condition
o
the engine oil and lets you
know when the oil should
be changed. (See “Engine
Oil” in the Index).
It does this using information about engine speed (revolutions per minute), coolant temperature and
vehicle speed. The system uses this data to determine
how much oil has degraded. of
the oil life has been used and each time the engine is
started after that.
If the “Change Oil Soon” light is on
continuously, there is a problem with the Oil Life
Monitor System and service is required.
After changing the engine oil, the system should be
reset.

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.

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.

3800 Supercharged (L67) Engine
(Option)
Your Park Avenue Ultra has a 3800 Supercharged
engine. Buick chose supercharging rather than
turbocharging because Buick emphasizes smooth,
refined power.
The Supercharger is a device which is designed to pump
more air into the engine than it would normally use.
This air mixed with fuel, creates increased engine
power. Since
the Supercharger is a pump and is driven
from an engine accessory drive belt, increased pressure
is available at all driving conditions.
The powertrain control module (PCM), works with a
vacuum control to regulate the increased pressure
required during specific driving conditions. When this
increased pressure or boost is not desired, such as during
idling and light throttle cruising, the excess air that the
Supercharger is pumping
is routed through a bypass. All
of these controls, working together provide high
performance character and
fuel efficiency in the 3800
V6 Supercharged Buick engine.
The power steering pump uses a remote reservoir
mounted on the throttle and cruise control cable bracket.
See “Maintenance Schedule’’ in
the Index for when you
should check the fluid.
Engine Accessory Belt
The Supercharged 3800 engine uses two accessory drive
belts. One belt drives the generator and the power
steering pump. The second belt drives the supercharger,
coolant pump and air conditioning compressor. Each
belt has its own tensioner and idler pulley.

Supercharger Oil
Unless you are technically qualified and have the proper
tools, you should
let your dealer or a qualified service
center perform this maintenance.
When to Check: Check oil level every 30,000 miles
(50,000 km) or every 36 months.
What Kind of Oil to Use: See “Recommended Fluids and
Lubricants”
in the Index. Use only the recommended oil.
How to Check and Add Oil: Check oil only when the
engine is cold. Allow the engine to cool
2 to 3 hours after
running.
1. Remove the wiring harness shield.
2. Clean the area around the oil fill plug before
removing
it.
3. Remove the oil fill plug using a 3/16 allen wrench.
4. The oil level is correct when it just reaches the
bottom
of the threads of the inspection hole.
5. Replace the oil plug with the O-ring in place. Torque
to 10 Nom (88 lb. in.).
6. Replace the wiring harness shield.
