2005 BUICK PARK AVENUE washer fluid

The Rainsense™ system is activated by turning the
wiper control band to one of the ve sensitivity levels
within the delay area. The delay position closest to OFF
is the lowest sensitivity setting, level one. The highest
sensitivity setting, level ve, is closest to the LO position.
A single wipe will occur each time you turn the wiper
control band to a higher sensitivity level to indicate that
the sensitivity level has been increased.
The windshield wipers also remain in a “high park”
position, stopped on the windshield and not in the
normal park position, even when the ignition is
turned off.
Notice:If you do not turn off the windshield wipers
when driving through an automatic car wash, you
could damage the wipers. Always turn off the
windshield wipers before entering an automatic
car wash.
The MIST and wash cycles operate as normal and are
not affected by the moisture-sensing function. The
system can be overridden at any time by manually
turning the wiper band to LO or HI speed.
Notice:Do not place stickers or other items on the
exterior glass surface directly in front of the
moisture sensor. Doing this could cause the
moisture sensor to malfunction.Windshield Washer
At the top of the multifunction lever there is a paddle
with the word PUSH on it. To spray washer uid on the
windshield, push the paddle. The wipers will clear
the window and either stop or return to your preset
speed. For more washer cycles, push and hold
the paddle.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
If your vehicle is equipped with a DIC, a WINDSHIELD
WASHER FLUID LOW message will appear on the
instrument panel cluster when the vehicle is low
on washer uid. SeeDIC Warnings and Messages on
page 3-49.
Cruise Control
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long trips.

DIC Warnings and Messages
Other warning messages may appear in the DIC
display. For Canadian drivers, in addition to the DIC
message your DIC will display EXP with a number after
it which reects the following messages:
EXP
(Export ID) Warning Message
23 DOOR AJAR
24 TRUNK AJAR
25 WINDSHIELD WASHER FLUID LOW
36 ENGINE OIL LOW – CHECK LEVEL
54 SERVICE STABILITY SYSTEM
55 STABILITY SYSTEM ACTIVE
82 CHANGE ENGINE OIL SOON
91TRACTION CONTROL
SYSTEM ACTIVE
140 TIRE PRESSURE LOW
The EXP codes are used to make translation from
English to other languages easier.
Pressing any of the DIC control buttons will remove
the messages or warnings from the DIC display.SERVICE STABILITY SYSTEM – 54:If you ever see
the SERVICE STABILITY SYSTEM message, it
means there may be a problem with your stability
enhancement system. If you see this message, try to
reset the system: stop, turn off the engine, then start the
engine again. If the SERVICE STABILITY SYSTEM
message still comes on, it means there is a problem.
You should see your GM dealer for service. Reduce
your speed and drive accordingly.
STABILITY SYSTEM ACTIVE – 55:You may see the
STABILITY SYSTEM ACTIVE message. It means
that an advanced, computer-controlled system has come
on to help your vehicle continue to go in the direction
in which you are steering. This stability enhancement
system activates when the computer senses that
your vehicle is just starting to spin, as it might if you hit
a patch of ice or other slippery spot on the road.
When the system is on, you may hear a noise or feel a
vibration in the brake pedal. This is normal.
When the STABILITY SYSTEM ACTIVE message is on,
you should continue to steer in the direction you want
to go. The system is designed to help you in bad
weather or other difficult driving situations by making the
most of whatever road conditions will permit. If the
STABILITY SYSTEM ACTIVE message comes on, you
will know that something has caused your vehicle to
start to spin, so you should consider slowing down.

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 are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles that
rst 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 is ready to go. If it needs
service, have it done before starting out. Of course, you
will nd experienced and able service experts in GM
dealerships all across North America. They will be ready
and willing to help if you need it.Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
Lamps:Are they all working? Are the lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inated to the
recommended pressure?
Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
Maps:Do you have up-to-date maps?

need to check your engine oil level right away. For
more information, seeDriver Information Center (DIC)
on page 3-46.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.

How to Check Power Steering Fluid
To check the power steering uid, do the following:
1. Turn the key off and let the engine compartment
cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a
clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the uid level on
the dipstick.
The level should be at the FULL COLD mark. If
necessary, add only enough uid to bring the level up to
the mark.
What to Use
To determine what kind of uid to use, seePart D:
Recommended Fluids and Lubricants on page 6-25.
Always use the proper uid. Failure to use the proper
uid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer uid, be sure to read
the manufacturer’s instructions before use. If you will
be operating your vehicle in an area where the
temperature may fall below freezing, use a uid that has
sufficient protection against freezing.
5-35

Adding Washer Fluid
If your vehicle has the Driver Information Center (DIC),
a WINDSHIELD WASHER FLUID LOW message
will be displayed when the windshield washer uid
reservoir is low. SeeDIC Warnings and Messages on
page 3-49for more information.
Open the cap with the
washer symbol on it. Add
washer uid until the
tank is full. SeeEngine
Compartment Overview
on page 5-12for
reservoir location.Notice:When using concentrated washer uid,
follow the manufacturer’s instructions for
adding water.
Do not mix water with ready-to-use washer uid.
Water can cause the solution to freeze and
damage your washer uid tank and other parts
of the washer system. Also, water does not
clean as well as washer uid.
Fill your washer uid tank only three-quarters
full when it is very cold. This allows for
expansion if freezing occurs, which could
damage the tank if it is completely full.
Do not use engine coolant (antifreeze) in your
windshield washer. It can damage your washer
system and paint.
5-36

Part B: Owner Checks and Services

which should be performed at the intervals specied to
help ensure the safety, dependability and emission
control performance of your vehicle.
Be sure any necessary repairs are completed at once.
Whenever any uids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
in Part D.
At Each Fuel Fill
It is important for you or a service station attendant to
perform these underhood checks at each fuel ll.
Engine Oil Level Check
Check the engine oil level and add the proper oil
if necessary. SeeEngine Oil on page 5-13for
further details.
Engine Coolant Level Check
