2005 Buick Park Avenue Owner ManualM

Engine Coolant Heater
If your vehicle has this feature, in very cold weather,
0°F (−18°C) or colder, the engine coolant heater
can help. You’ll get easier starting and better fuel
economy during engine warm-up. Usually, the coolant
heater should be plugged in a minimum of four
hours prior to starting your vehicle. At temperatures
above 32°F (0°C), use of the coolant heater is
not required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located on the
passenger’s side of the vehicle, above the
headlamp assembly.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you don’t, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

Outside Convex Mirror
The passenger’s side mirror is convex. A convex
mirror’s surface is curved so more can be seen from the
driver’s seat.
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
Outside Automatic Dimming
Heated Mirror
If the vehicle has this feature, the driver’s side outside
rearview mirror will adjust for the glare of headlamps
behind you. This feature is controlled using the on and
off settings on the automatic dimming rearview
mirror. See “Automatic Dimming Rearview Mirror” or
“Automatic Dimming Rearview Mirror with Compass”
earlier in this section.
The outside mirrors will heat up to dissolve ice, snow or
fog when the rear window defogger is turned on. See
“Rear Window Defogger” underDual Automatic Climate
Control System on page 3-25.

Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
Turn and Lane-Change Signals. SeeTurn and
Lane-Change Signals on page 3-7.
Headlamp High/Low-Beam Changer. SeeHeadlamp
High/Low-Beam Changer on page 3-8.
Flash-to-Pass. SeeFlash-to-Pass on page 3-9.
Windshield Wipers. SeeWindshield Wipers on
page 3-9.
Windshield Washer. SeeWindshield Washer on
page 3-10.
Cruise Control. SeeCruise Control on page 3-10.
For information on the exterior lamps, seeExterior
Lamps on page 3-14.
Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up
or down. When the turn is nished, the lever will
return automatically.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
3-7

If your vehicle is equipped with the Head-Up Display
(HUD), an arrow will also appear in the display area to
indicate the direction of the turn or lane change.
SeeHead-Up Display (HUD) on page 3-19for
more information.
You may also have an arrow in the outside mirror that
ashes when the turn signal is used. SeeOutside Power
Mirrors on page 2-37for more information.
To signal a lane change, just raise or lower the lever
until the arrow starts to ash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
As you signal a turn or a lane change, if the arrows
ash at twice the normal rate, this may indicate that a
signal bulb may be burned out and other drivers will not
see your turn signal. If a bulb is burned out, replace
it to help avoid an accident.
If the arrows do not go on at all when you signal a turn,
check the fuse and check for burned-out bulbs. See
Fuses and Circuit Breakers on page 5-92.
If you have a trailer towing option with added wiring for
the trailer lamps, the signal indicator will ash even
if a turn signal bulb is burned out. Check the front and
rear turn signal lamps regularly to make sure they
are working. You do not need to add a different asher.Turn Signal On Chime
If your turn signal is left on for more than three-quarters
of a mile (1.2 km), a chime will sound at each ash
of the turn signal. To turn off the chime, move the turn
signal lever to the off position.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high
beam or high beam to low beam, pull the turn signal
lever toward you and release it.
While the high beams are
on, this light located on the
instrument panel cluster
will also be on.
If your vehicle is equipped with the Head-Up
Display (HUD), this symbol will also appear in the
display area to indicate the high beams are on.
SeeHead-Up Display (HUD) on page 3-19for
more information.
3-8

Flash-to-Pass
This feature lets you use the high-beam headlamps to
signal the driver in front of you that you want to pass. It
works even if your headlamps are off.
Pull the turn signal lever toward you briey to
ash-to-pass.
If the headlamps are off or on low beam, the high-beam
headlamps will turn on. They will stay on as long as
you hold the lever toward you and the high-beam
indicator on the instrument panel cluster will come on.
Windshield Wipers
The windshield wipers are controlled by turning the
band marked WIPER.
OFF:Turn the band to OFF to turn the wipers off.
MIST:For a single wiping cycle, turn the band to MIST.
Hold it there until the wipers start, then let go. The
wipers will stop after one cycle. If you want more cycles,
hold the band on MIST longer.
LO (Low Speed):Turn the band to LO for steady
wiping at a slow speed.
HI (High Speed):Turn the band to HI for steady wiping
at a high speed.The wiper speed may be set for a long or short delay
between wipes. Turn the band to choose the delay time.
The closer to LO, the shorter the delay.
Heavy snow or ice can overload your wiper motor. A
circuit breaker will stop the motor until it cools.
Clear away snow or ice to prevent an overload.
Keep in mind that damaged wiper blades may prevent
you from seeing well enough to drive safely. To
avoid damage, be sure to clear ice and snow from the
wiper blades before using them. If your blades do
become damaged, get new blades or blade inserts.
Rainsense™ II Wipers
If your vehicle has this feature, the moisture sensor is
mounted on the interior of the windshield below the
rearview mirror and is used to automatically operate the
wipers. This system operates by monitoring the
amount of moisture build-up on the windshield. Wipes
occur as needed to clear the windshield depending
on the driving conditions and the sensitivity setting. In
light rain or snow, fewer wipes will occur. In heavy
rain or snow, wipes will occur more frequently.
The system will operate in the delay, low speed and
high speed modes. If the system is left on for long
periods of time, occasional wipes may occur without any
moisture on the windshield. This is normal and
indicates that the Rainsense™ system is active.
