2005 BUICK CENTURY windshield wipers

Ignition Positions
With the ignition key in the ignition, the key can be
turned to ve different positions:
A (ACCESSORY):This position lets the radio and
windshield wipers operate when the engine is off.
To use ACCESSORY, push in the key and turn
it counterclockwise.B (LOCK):This is the only position in which the ignition
key can be inserted or removed. This position locks
the ignition and transaxle. It is a theft-deterrent feature.
Notice:If your key seems stuck in LOCK and
you can not turn it, be sure you are using the correct
key; if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. Turn the key only with your hand. Using a
tool to force it could break the key or the ignition
switch. If none of these works, then your vehicle
needs service.
C (OFF):In this position the engine is off. Use the
OFF position if the vehicle must be pushed or towed.
D (RUN):This position is where the key returns to after
the vehicle is started. This position displays some of
the warning and indicator lights.
E (START):This position starts the engine.
A warning chime will sound when the driver’s door is
opened if the ignition is in OFF, LOCK or ACCESSORY
and the key is in the ignition.

Turn Signal/Multifunction Lever
The multifunction lever located on the left side of the
steering column includes the following:
Turn and Lane-Change Signals
Headlamp High/Low-Beam Changer
Flash-to-Pass
Windshield Wipers
Windshield Washer
Cruise Control
Turn and Lane-Change Signals
To signal a turn, move the turn signal/multifunction lever
up or down. The lever returns to its original position
when the turn is completed.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
To signal a lane change, raise or lower the turn signal/
multifunction lever until the arrow starts to ash. Hold it
there until the lane change is completed. The lever will
return to its original position when released.
Arrows that ash rapidly when signaling for a turn or
lane change, or that fail to work, may indicate a
burned-out signal bulb or fuse. Other drivers will not see
the signal. SeeFront Turn Signal and Parking Lamps
on page 5-48andTaillamps, Turn Signal, and
Stoplamps on page 5-50for turn signal bulb replacement
procedures. Also seeFuses and Circuit Breakers on
page 5-91for location of fuses.
A chime will sound if the turn signal is left on for more
than 3/4 mile (1.2 km).

Headlamp High/Low-Beam Changer
To change the headlamps from low beams to high
beams, or high to low, pull the multifunction lever until
a click is heard, then release it.
This indicator light on the
instrument panel cluster
will come on while the
high-beam lamps are on.
Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal the driver in front of you that you want to pass.
It works even if the headlamps are off. Pull the turn
signal lever toward you a little, but not so much that you
hear a click.
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. The high-beam indicator
on the instrument panel cluster will come on. Release
the lever to return it to the normal operation.
Windshield Wipers
To operate the windshield wipers turn the band located
on the multifunction lever upward or downward.
WIPER:Turn this band to control the windshield wipers.
OFF:Turn the band to OFF to turn off the
windshield wipers.
LO (Low Speed):Turn the band away from you
to LO and past the delay settings for steady wiping at
low speed.
HI (High Speed):Turn the band away from you, to HI,
and past the delay settings for steady wiping at a
high speed.
(Delayed Wiping):Turn the band away from you,
just past OFF, to one of the ve delayed settings,
to choose the length of intervals between each wiping
cycle. The further the band is turned upward, toward LO,
the shorter the delay will be. Select one of these
settings for light rain or snow.
3-8

MIST:Turn the band to MIST for a single wiping cycle.
Hold it until the windshield wipers start. Then let it
go. The windshield wipers will stop after one wipe.
If more wipes are needed, hold the band on
MIST longer.
Be sure to clear ice and snow from the windshield wiper
blades before using them. If they are frozen to the
windshield, carefully loosen or thaw them. If the blades
do become worn or damaged, get new blades or
blade inserts. SeeWindshield Wiper Blade Replacement
on page 5-52.
Heavy snow or ice can overload the wipers. A circuit
breaker will stop them until the motor cools. Clear away
snow or ice to prevent an overload.Windshield Washer
J(Windshield Washer):A paddle with the word
PUSH on it is located at the top of the multifunction
lever. Push on the paddle to spray washer uid on the
windshield. The wipers will run for several sweeps
and then either stop or return to the preset speed.
SeeWindshield Washer Fluid on page 5-35.
{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.
The LOW WASH light on
the instrument panel
cluster will come on when
the uid level is low.

Outlet Adjustment
Use the louvers located on the air outlets to change the
direction of the airow.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the vehicle that may block
the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle
more effectively.
Passenger Compartment Air Filter
The passenger compartment air lter is located in
the engine compartment below the air inlet grille,
near the passenger’s side windshield wiper arm.
The lter traps most of the pollen from the air entering
the air conditioning module. Like the engine’s air cleaner
lter, it may need to be changed periodically. For
information on how often to change the passenger
compartment air lter, seeScheduled Maintenance on
page 6-4.
To change the passenger compartment air lter, use the
following steps:
1. Turn the ignition to ACCESSORY and turn the
windshield wipers on.
2. Turn the ignition to OFF when the windshield
wipers are in the upright position.
3. Raise the hood.
4. Disconnect the windshield washer pump hose from
the fender rail and air inlet grille.

Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for wear
or cracking each time maintenance is performed.
SeeScheduled Maintenance on page 6-4.
1. Turn on the wipers to LO.
2. Turn off the ignition while the wipers are at the
outer positions of the wiper pattern. The blades
are more accessible for removal or replacement
while in this position.
3. Pull the windshield wiper arm 3 to 4 inches
(7.5 to 10 cm) away from the windshield.
4. While holding the wiper arm away from the glass,
push the release clip from under the windshield
wiper arm connecting point and slide the blade
assembly down toward the glass to remove it from
the wiper arm.
5. Slide the new wiper blade securely on the wiper
arm until you hear the release clip click into
place. SeeNormal Maintenance Replacement Parts
on page 6-14for the type of windshield wiper
blades to use.
