2004 BUICK PARK AVENUE tow

REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transaxle.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transaxle, see
If You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-30.
NEUTRAL (N):In this position, your engine doesn’t
connect with the wheels. To restart when you’re already
moving, use NEUTRAL (N) only. Also, use NEUTRAL (N)
when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine racing may damage the transaxle.
The repairs would not be covered by your warranty.
Be sure the engine is not racing when shifting
your vehicle.
AUTOMATIC OVERDRIVE (
X):This position is for
normal driving. If you need more power for passing,
and you’re:
Going less than about 35 mph (55 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You’ll shift down to the next gear and have more power.
THIRD (3):This position is also used for normal
driving. However, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (
X).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (
X):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
When going down a steep hill.

If you try to drive with the parking brake on, after about
20 feet (6.1 m) a chime will sound continuously until
you release the parking brake. Also, the brake light will
stay on until the parking brake is released.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-38. That part shows
what to do rst to keep the trailer from moving.Shifting Into Park (P)
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle will
not move, even when you are on fairly level
ground, use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 4-38.

Leaving Your Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and
your parking brake is rmly set before you leave it.
After you’ve moved the shift lever into PARK (P), hold
the regular brake pedal down. Then, see if you can
move the shift lever away from PARK (P) without rst
pulling it toward you. If you can, it means that the
shift lever wasn’t fully locked into PARK (P).
Torque Lock
If you are parking on a hill and you don’t shift your
transaxle into PARK (P) properly, the weight of
the vehicle may put too much force on the parking pawl
in the transaxle. You may nd it difficult to pull the
shift lever out of PARK (P). This is called “torque lock.”
To prevent torque lock, set the parking brake and
then shift into PARK (P) properly before you leave the
driver’s seat. To nd out how, seeShifting Into Park (P)
on page 2-30.
When you are ready to drive, move the shift lever out
of PARK (P)beforeyou release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transaxle, so you
can pull the shift lever out of PARK (P).

Running Your Engine While You
Are Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
Engine Exhaust on page 2-34.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 4-26.
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. Do not leave your vehicle when the engine
is running unless you have to. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move, even
when you are on fairly level ground, always set
your parking brake and move the shift lever
to PARK (P).
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park (P) on page 2-30.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-38.

Automatic Dimming Rearview
Mirror with Compass
Your vehicle may have an automatic dimming rearview
mirror with a compass. Your vehicle’s mirror may
also contain OnStar
®controls. SeeOnStar®System on
page 2-41for more information.
The mirror also includes an eight-point compass display
in the upper right corner of the mirror face.
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.
Mirror Operation
MIRROR:Press this button to turn on the automatic
dimming feature. Press it again to turn off the automatic
dimming feature.
O(On/Off):For mirrors equipped with OnStar®
controls, press and hold this button for several seconds
to turn on the automatic dimming feature. Press and
hold it again to turn the automatic dimming feature off.
The green indicator light will come on when this
feature is active. The automatic dimming feature will be
active each time the vehicle is started.
Compass Operation
COMPASS:Press this button once to turn the compass
on or off.
O(On/Off):For mirrors equipped with OnStar®controls,
press this button once to turn the compass on or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for about
two seconds. After two seconds, the mirror will display
the compass heading.
Compass Calibration
When on, the compass automatically calibrates as the
vehicle is driven. If, after two seconds, the display
does not show a compass heading (N for North,
for example), there may be a strong magnetic eld
interfering with the compass. Such interference may be
caused by a magnetic antenna mount, magnetic
note pad holder or a similar magnetic item. If the letter
C should ever appear in the compass window, the
compass may need calibration.
The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display reads
a direction.
Mirrors equipped with OnStar
®controls can be placed
in calibration mode by pressing and holding the
on/off button untilaCisshown in the compass display.
