2006 BUICK LACROSSE lights

Entry lighting includes a feature called theater dimming.
With theater dimming, the lamps do not turn off at the end
of the delay time. Instead, they slowly dim after the delay
time and then turn off.
The courtesy lamps turn off when the ignition key is
turned to RUN or START. They will come on again when
a door is opened.
Delayed Entry Lighting
Delayed entry lighting lights the vehicle’s interior for a
period of time after all the doors have been closed.
After all the doors have been closed, the delayed entry
lighting feature will continue to work until one of the
following occurs:
The ignition is in run.
The doors are locked.
Twenty-ve seconds has elapsed.
If during the illumination period a door is opened, the
timed illumination period will be canceled and the interior
lamps will remain on.
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
This feature can be programmed either on or off
using the Driver Information Center. SeeDIC Vehicle
Personalization on page 3-75under INT LIGHTS KEYS
REMOVED. When activated, this feature illuminates
the interior for a period of time after the ignition key is
removed from the ignition.
The ignition must be off and the interior lamp control
must be in the door position for delayed exit lighting
to work. When the ignition key is removed, interior
illumination will activate and remain on until one of the
following occurs:
The ignition is in RUN.
The power door locks are activated.
Twenty-ve seconds has elapsed.
If during the illumination period a door is opened, the
timed illumination period will be canceled and the interior
lamps will remain on.

The URPA display is located inside the vehicle, above the
rear window. It has three color-coded lights that can be
seen through the rearview mirror or by turning around.
{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not operate above
typical backing speeds of 3 mph (5 km/h) while
parking. And, the system does not detect
objects that are more than 5 feet (1.5 meters)
behind the vehicle.
So, unless you check carefully behind you
before and when you back up, you could strike
children, pedestrians, bicyclists or pets behind
you, and they could be injured or killed.
Whether or not you are using rear park assist,
always check carefully behind your vehicle
before you back up and then watch closely as
you do.
How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R). When the system comes on,
the three lights on the display will briey illuminate to let
you know that the system is working. If your vehicle is
moving in REVERSE (R) at a speed greater than 3 mph
(5 km/h), the red light will ash to remind you the system
does not work at this speed.
The rst time an object is detected while in
REVERSE (R), a chime will sound and the following
will occur in sequence, depending on the distance from
the object:
At 5 feet (1.5 m) a chime will sound and one amber
light will be lit.
At 40 inches (1.0 m) both amber lights will be lit.
At 20 inches (0.5 m) a continuous chime will sound
and all three lights (amber/amber/red) will be lit.
At 1 foot (0.3 m) a continuous chime will sound and
all three lights (amber/amber/red) will ash.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the
rear sensors to recognize an object, it must be within
operating range.

feature, you can control
the driver’s temperature
setting by using the
control located on your
steering wheel.
yz(Temperature):Press the up arrow to increase
or the down arrow decrease the temperature inside
your vehicle.
Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that may
be on the vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to the
warning lights and gages could also save you or others
from injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. As you will
see in the details on the next few pages, some warning
lights come on briey when you start the engine just to let
you know they are working. If you are familiar with this
section, you should not be alarmed when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages and
warning lights work together to let you know when there
is a problem with your vehicle.
When one of the warning lights comes on and stays
on when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this manual’s
advice. Waiting to do repairs can be costly – and even
dangerous. So please get to know the warning lights and
gages. They are a big help.

If, after several seconds, all status indicator lights remain
on, or if there are no lights at all, there may be a problem
with the lights or the passenger sensing system. See your
dealer for service.
{CAUTION:
If the off indicator and the airbag readiness light
ever come on together, it means that something
may be wrong with the airbag system. If this
ever happens, have the vehicle serviced
promptly, because an adult-size person sitting
in the right front passenger seat may not have
the protection of the frontal airbag. SeeAirbag
Readiness Light on page 3-34.
Charging System Light
The charging system light
will come on briey when
the ignition is turned on,
as a check to show that it
is working. Then it should
go out.
If it stays on, or comes on while the vehicle is being
driven, a chime will sound and there may be a problem
with the charging system. It could indicate that the
vehicle has a loose accessory belt or another electrical
problem. Have it checked right away. Driving while
this light is on could drain the battery.
If the vehicle must be driven a short distance with the
light on, be certain to turn off all the accessories,
such as the radio and air conditioner.

What you do in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes
will have less trouble adjusting to night. But if you
are driving, do not wear sunglasses at night. They may
cut down on glare from headlamps, but they also
make a lot of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even
several seconds, for your eyes to re-adjust to the dark.
When you are faced with severe glare, as from a
driver who does not lower the high beams, or a vehicle
with misaimed headlamps, slow down a little. Avoid
staring directly into the approaching headlamps.
Keep the windshield and all the glass on your vehicle
clean — inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a lm caused by dust. Dirty glass makes
lights dazzle and ash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that the headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it is easier to pick out dimly lighted
objects. Just as the headlamps should be checked
regularly for proper aim, so should your eyes be
examined regularly. Some drivers suffer from night
blindness — the inability to see in dim light — and are
not even aware of it.Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a
wet road, you cannot stop, accelerate, or turn as well
because your tire-to-road traction is not as good as
on dry roads. And, if your tires do not have much tread
left, you will get even less traction. It is always wise
to go slower and be cautious if rain starts to fall while
you are driving. The surface may get wet suddenly when
your reexes are tuned for driving on dry pavement.
