2006 BUICK LUCERNE Owner's Manual

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 you do this, 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, your vehicle will
slow down to the cruise speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your 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 takes you out of 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
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.

Wiper Activated Headlamps
This feature turns on the low-beam headlamps,
instrument panel cluster backlighting and taillamps
when the windshield wipers have been in use for about
six seconds.
If the wiper activated headlamps are on and the ignition
switch is turned to C (RUN), the wiper activated
headlamps will continue. When you turn the key to
A (OFF), the wiper activated headlamps will immediately
turn off. The wiper activated headlamps will also turn
off if you turn off the windshield wipers.
Headlamps on Reminder
If you leave the exterior lamp buttons for the headlamps
or parking lamps on, remove the key from the ignition
and open the driver’s door, you will hear a continuous
warning chime. The chime will turn off when the lamps
are turned off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL, so
be sure it is not covered.
The DRL system will make your low-beam headlamps
turn on at reduced brightness in daylight when the
following conditions are met:
The ignition is on.
The exterior lamp button for the headlamps is off.
The automatic transaxle is not in PARK (P).
When the DRL are on, only your low-beam headlamps
will be on. The parking lamps, taillamps, sidemarker
and other lamps will not be on.
When it is dark enough outside, your low-beam
headlamps will come on. The other lamps that turn on
with your headlamps will also turn on. When it is
bright enough outside, the regular lamps will go off, and
your low-beam headlamps change to the reduced
brightness of DRL.
To turn off all exterior lighting at night when you are
parked, turn the exterior lamp control to the off position.
The exterior lamps will turn back on automatically
when you move the transaxle out of PARK (P).
SeeExterior Lamps on page 3-14for more information.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
3-15

Fog Lamps
-(Fog Lamps):If your vehicle is equipped with fog
lamps, it is located on the exterior lamps control.
The exterior lamps control is located on the instrument
panel to the left of the steering column.
Your ignition must be in C (RUN) for the fog lamps to
illuminate.
To turn the fog lamps on, press the exterior lamps button.
A light will come on in the instrument panel cluster to let
you know that the fog lamps are on. Press the exterior
lamps button again to turn the fog lamps off.
The ignition must be in C (RUN) and the parking lamps
must be on for your fog lamps to work.
The fog lamps will go off while you change to high-beam
headlamps.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Cornering Lamps
If your vehicle has this feature, the cornering lamps
come on when: the headlamps or parking lamps are on,
the vehicle is not in PARK (P), and you signal a turn
with the turn signal/multifunction lever. They provide
more light for cornering.
Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exterior
lamps will turn off about 10 minutes after the ignition
is turned to A (OFF) and a door has been opened.
This protects against draining the battery in case you
have accidentally left the headlamps or parking
lamps on. If you need to leave the lamps on for more
than 10 minutes, use the manual control to turn the
lamps back on after the ignition is turned to A (OFF) and
any door is opened. To delay the lamps from turning
off, seeDIC Vehicle Customization on page 3-65.

Courtesy Lamps
If it is dark enough outside, when any door is opened,
several lamps go on. They make it easy for you to enter
and leave the vehicle. Turn these lamps on manually
by turning the instrument panel brightness control
completely clockwise.
Entry Lighting
If it is dark enough outside when you press the unlock
button on the remote keyless entry transmitter, the
interior courtesy lamps will turn on and stay on for about
40 seconds. The lamps can be turned off immediately
by pressing the lock button on the remote keyless entry
transmitter, turning the ignition key to C (RUN) or
activating the power door locks.
Delayed Entry Lighting
The interior lamps will turn on if you open the door when it
is dark enough outside. When you close the door with
the ignition off, the interior lamps will stay on for up to
25 seconds or until the ignition is turned to an on position.
When the lamps turn off as a result of the 25 second
timer or the ignition switch being turned on, the lighting
will deactivate by way of the theater dimming effect.
Locking the doors will override the delayed entry lighting
feature and the lamps will turn off right away.
Theater Dimming
This feature allows for a three to ve-second fade out of
the courtesy lamps instead of immediate turn off.
Delayed Exit Lighting
If it is dark enough outside when you remove the key
from the ignition, the interior lamps will turn on and
stay on for about 25 seconds. This will give you time to
nd the door pull handle or lock switches. Once the
key is inserted into the ignition, the exit lighting will be
cancelled and the lighting will fade out.
Perimeter Lighting
If it is dark enough outside when the unlock button on
the remote keyless entry transmitter is pressed, the
DRL, parking lamps and back-up lamps will come on.
This feature can be programmed in the on for various
amounts of seconds or off mode for each transmitter.
SeeDIC Vehicle Customization on page 3-65for
information on programming.
3-17

Front Reading Lamps
The front reading lamps, located on the headliner, are
turned on or off by pressing one of the buttons
located near each lamp.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher RPM setting than normal to make sure the
battery charges. High electrical loads may occur when
several of the following are on: headlamps, high beams,
rear window defogger, fan at high speed, heated
seats (if equipped), and engine cooling fans.
If your vehicle’s battery remains in a heavy discharge
condition for a long period of time, the fan, rear
defogger, heated seats, and heated mirrors will be
disabled and the DIC will display SERVICE BATTERY
CHARGING SYSTEM. This can happen either under
long periods of idling or low speed driving with high
electrical loading, or in the event of a charging system
fault. SeeDIC Warnings and Messages on page 3-56
for more information.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, or garage
door opener. When the ignition is turned off, the power
to these features will automatically turn off after
10 minutes. Power will be restored for an additional
10 minutes if any door is opened, the trunk is opened or
the courtesy lamp switch is turned on.
Ultrasonic Rear Parking
Assist (URPA)
If your vehicle is equipped, the Ultrasonic Rear Parking
Assist (URPA) system is designed to help you park
while in REVERSE (R). It operates only at speeds less
than 5 mph (8 km/h). URPA helps make parking
easier and helps you avoid colliding with objects such
as parked vehicles. The URPA system detects
objects that are close to the rear of the vehicle which
are at least 10 inches (25.4 cm) off the ground and
below hood or trunk level. The system detects objects
up to 8 feet (2.5 m) behind your vehicle. URPA
determines how close these objects are from your
bumper within this area. Ultrasonic sensors on the rear
bumper are used to detect the distance to the object.
3-18

{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not operate above
speeds of 5 mph (8 km/h). The system does not
detect objects more than 8 feet (2.5 meters)
behind the vehicle. Also, the system does not
detect objects that are below your bumper,
underneath your vehicle, or some objects very
close to the vehicle. The system is not designed
to detect children, pedestrians, bicyclists,
or pets.
So, unless you check carefully behind your
vehicle while you are backing up, they could be
injured or killed.
Whether or not you are using rear park assist,
always check carefully behind your vehicle
before backing up and then watch closely
as you do.The display is located near
the rear window and can
be seen by looking
over your right shoulder.
The display has three color-coded lights. The URPA
lights are used to provide distance and system
information, along with beeps played out the speakers.
How the System Works
When the shift lever is moved into REVERSE (R),
the rear display will briey illuminate to let you know
the display is operating correctly. URPA comes on
automatically when the shift lever is moved into
REVERSE (R). The system also does not work at a
reverse speed greater than 5 mph (8 km/h). To remind
you of this, the red light on the rear display will ash.
The system can be disabled using the Driver Information
Center (DIC). SeeDIC Controls and Displays on
page 3-50.
3-19

How the System Works when Backing
If the shift lever is in REVERSE (R), URPA detects
objects close to the rear bumper. The rst time an object
is detected a single beep will sound. If an object is
detected at a REVERSE (R) speed between 0 mph
(0 km/h) and 5 mph (8 km/h), the following describes
what will occur based on your distance to a detected
object located behind the vehicle:
At distances between 40 inches (1 m) and
8 ft (2.5 m), a single amber light will be lit.
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be lit.
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all three lights (amber/amber/red)
will be lit.
At distances less than 12 inches (0.3 m), a beeping
sound will repeat for a short time and all three lights
(amber/amber/red) will be lit and ashing.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, the message PARK ASSIST OFF will be
displayed on the DIC and a red light will be shown on the
rear URPA display when the shift lever is moved into
REVERSE (R). This occurs under the following conditions:
The driver disables the system. SeeDIC Controls
and Displays on page 3-50.
The parking brake pedal is depressed.
A trailer was attached to your vehicle, or a bicycle
or an object was hanging out of your trunk during
your last drive when you turned off the vehicle.
If the attached objects are removed from your
vehicle before the start of your next drive,
the system will return to normal operation unless
an object is detected when the vehicle is shifted into
REVERSE (R). If this occurs, URPA assumes the
object is still attached, so you will have to wait until
the vehicle is driven forward above 15 mph (25 km/h)
before URPA will return to normal operation.
