BUICK LUCERNE 2007 Owner's Manual

Tilt Wheel
A tilt wheel allows you to adjust the steering wheel
before you drive. You can also raise it to the
highest level to give your legs more room when
you exit and enter the vehicle.
The lever that allows you to tilt the steering wheel
is located on the left side of the steering column.
To tilt the wheel, hold
the wheel and pull the
lever toward you. Then
move the wheel to a
comfortable position and
release the lever to lock
the wheel in place.
Heated Steering Wheel
Your vehicle may have a heated steering wheel.
The button for this
feature is located on
the left side of the
steering wheel.
Press the button to turn the heated steering wheel
on or off. A light on the button will display when
the feature is turned on.
The steering wheel will take about three minutes
to start heating.

The lever on the left side of the steering column
includes the following:
GTurn and Lane-Change Signals. See
Turn and Lane-Change Signals on page 162.
3Headlamp High/Low-Beam Changer.
SeeHeadlamp High/Low-Beam Changer on
page 163.
Flash-To-Pass Feature. SeeFlash-to-Pass on
page 164.
NWindshield Wipers. SeeWindshield Wipers
on page 164.
LWindshield Washer. SeeWindshield

Turn and Lane-Change Signals
To signal a turn, move the lever on the left side of
the steering wheel all the way up or down. The lever
returns automatically when the turn is complete.
An arrow on the
instrument panel
cluster will ash in the
direction of the turn or
lane change.
You may also have an arrow in the outside mirror
that ashes when the turn signal is used. See
Outside Power Mirrors on page 133for more
information.
162

Raise or lower the lever until the arrow starts to
ash to signal a lane change. Hold it there until the
lane change is complete. If you momentarily press
and release the lever, the turn signal will ash
three times.
If the arrows ash very fast as you signal a turn or a
lane change, 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. SeeFuses and Circuit
Breakers on page 428.
Turn Signal On Chime
If your turn signal is left on for more than
0.8 miles (1.3 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, push the turn signal lever away from
you. To change from high beam to low beam,
pull the turn signal lever toward you.
While the high beams
are on, this light located
on the instrument
panel cluster will
also be on.
163

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
You control the windshield wipers by turning the
band with the wiper symbol on it.
8(Mist):Turn the band to mist for a single wiping
cycle. Hold it there until the wipers start. Then let
go. The wipers stop after one wipe. For more wipe
cycles, hold the band longer on mist.
6(Delay):Turn the band to choose the delay time
between wipe cycles. The wiper speed can be set
for a long or short delay between wipes. The closer
the band is set to the top of the lever, the shorter
the delay.
6(Low Speed):Turn the band away from
you to the rst solid band past the delay settings
for steady wiping at low speed.
1(High Speed):For high-speed wiping, turn
the band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band to off.
Clear ice and snow from the wiper blades before
using them. If they are frozen to the windshield,
carefully loosen or thaw them. If the blades
become worn or damaged, replace with new
blades or blade inserts.
Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools. Clear
away snow or ice to prevent an overload.
Your vehicle has wiper-activated headlamps. After
the windshield wipers have completed eight
wipe cycles within four minutes, the headlamps
automatically turn on. SeeWiper Activated
Headlamps on page 171for more information.
164

Rainsense™ II Wipers
If your vehicle has this feature, the moisture sensor
is mounted on the interior of the windshield beside
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 operates in the
delay mode. 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.
The Rainsense™ system is activated by turning
the wiper control band to one of the ve sensitivity
levels within the delay area. The position closest
to off is the lowest sensitivity setting, level one.This allows more rain or snow to collect on the
windshield between wipes. Turning the wiper band
away from you to higher sensitivity levels increases
the sensitivity of the system and frequency of
wipes. The highest sensitivity setting, level ve is
closest to low. A single wipe will occur each time
you turn the wiper stalk to a higher sensitivity level
to indicate that the sensitivity level has been
increased.
Notice:Going through an automatic car wash
with the wipers on can damage them. Turn the
wipers off when going through an automatic
car wash.
The MIST and wash cycles operate as normal and
are not affected by the Rainsense™ function. The
system can be overridden at any time by manually
changing the wiper control to low or high speed.
Notice:Do not place stickers or other items
on the exterior glass surface directly in front of
the rain sensor. Doing this could cause the
rain sensor to malfunction.
165

Windshield Washer
{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.
J(Washer Fluid):Press and release this
paddle, located at the top of the turn signal/
multifunction lever, to spray washer uid on the
windshield. The wipers will clear the windshield
and either stop or return to your preset speed. For
more washer cycles, press and hold the paddle.
_(Heated Washer Fluid):The heated
windshield washer uid system, if your vehicle has
this feature, may be used to help clear ice, snow,
tree sap, or bugs from your windshield. Sliding the
switch on the turn signal/multifunction lever to
this position and then releasing it will activate the
heated windshield washer uid system. This
activation will initiate four heated wash/wipe cycles.
The rst heated wash/wipe cycle may take up to
40 seconds to occur, depending on outside
temperature. After the rst wash/wipe cycle, it may
take up to 20 seconds for each of the remaining
cycles. The heated windshield washer uid system
may be turned off at any time by sliding the switch
on the turn signal/multifunction lever to this
position again.
When the heated windshield washer uid system
is activated under certain outside temperature
conditions, steam may ow out of the washer
nozzles for a short period of time before washer
uid is sprayed. This is a normal condition.
Washer Fluid Low Add Fluid will be displayed on
the Driver Information Center (DIC) when the
washer uid is low. SeeDIC Warnings and
Messages on page 221.

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. Cruise control does not work at speeds
below about 25 mph (40 km/h).
{CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not use your cruise control on
winding roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could
lose control. Do not use cruise control
on slippery roads.If your vehicle is in cruise control when the traction
control system, if your vehicle has this feature,
begins to limit wheel spin, the cruise control will
automatically disengage. SeeTraction Control
System (TCS) on page 283. When road conditions
allow you to safely use it again, the cruise control
can be turned back on.
The cruise control
buttons are located
on left side of the
steering wheel.
T(On/Off):Press this button to turn cruise
control on and off. The indicator will be lit
when cruise control is on.
167

+ RES (Resume/Accelerate):Press this button
to make the vehicle accelerate or resume to
a previously set speed.
SET–:Press this button to set the speed or
make the vehicle decelerate.
[(Cancel):Press this button to cancel cruise
control.
Setting Cruise Control
Cruise control will not work if the parking brake is
set, or if the master cylinder brake uid level is low.
The cruise control light on the instrument panel
cluster will come on after the cruise control
has been set to the desired speed. See
Instrument Panel Cluster on page 194.
{CAUTION:
If you leave your cruise control on when
you are not using cruise, you might hit a
button and go into cruise when you do
not want to. You could be startled and
even lose control. Keep the cruise control
switch off until you want to use cruise
control.
1. Press the cruise control on/off button.
2. Get up to the speed you want.
3. Press and release the SET– button located on
the steering wheel.
4. Take your foot off the accelerator.
168

Resuming a Set Speed
Suppose you set the cruise control at a desired
speed and then you apply the brake. This shuts off
the cruise control, but it does not need to be reset.
Once you are driving about 25 mph (40 km/h) or
more, press the +RES button on the steering
wheel. The vehicle will go back to your chosen
speed and stay there.
Increasing Speed While Using Cruise
Control
To increase the cruise speed while using cruise
control:
Press and hold the +RES button on the
steering wheel until you reach your new
desired speed, then release it.
To increase vehicle speed in small increments,
press the +RES button.
Reducing Speed While Using Cruise
Control
To reduce your speed while using cruise control:
Press and hold the SET– button on the
steering wheel until you reach the lower
speed you want, then release it.
To slow down in very small amounts, press
the SET– button on the steering wheel
briey. Each time this is done, you will
go about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase vehicle
speed. When you take your foot off the pedal, the
vehicle will slow down to the cruise speed you
set earlier.
169

Using Cruise Control on Hills
How well the cruise control will work on hills
depends upon the vehicle speed, load and the
steepness of the hills. When going up steep hills,
you may have to step on the accelerator pedal
to maintain your speed. When going downhill, you
may have to brake or shift to a lower gear to
keep your speed down. Of course, applying the
brake ends the cruise control. Many drivers
nd this to be too much trouble and do not use
cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the[(cancel) button on the steering
wheel.
Press theT(on/off) button on the steering
wheel.
Erasing Speed Memory
The cruise control set speed memory is erased by
turning off the cruise control or the ignition.
Exterior Lamps
The exterior lamps
control is located on
the instrument panel
to the left of the
steering wheel.
It controls the following systems:
Headlamps
Taillamps
Parking Lamps
License Plate Lamps
Instrument Panel Lights
Fog Lamps
