Keep the original hand-held
transmitter for use in other vehicles
as well as for future Universal
Remote system programming. It is
also recommended that upon the
sale of the vehicle, the programmed
Universal Remote system buttons
be erased for security purposes.
See“Erasing Universal Remote
System Buttons” later in this
section.
When programming a garage door,
park outside of the garage. Park
directly in line with and facing the
garage door opener motor-head
or gate motor-head. Be sure that
people and objects are clear of
the garage door or gate being
programmed.
It is recommended that a new
battery be installed in the hand-held
transmitter for quicker and more
accurate transmission of the
radio-frequency signal.Programming the Universal
Remote System
For questions or help programming
the Universal Remote system,
call 1‐800‐355‐3515 or go to
www.homelink.com.
Programming a garage door opener
involves time-sensitive actions, so
read the entire procedure before
starting. Otherwise, the device will
time out and the procedure will have
to be repeated.
To program up to three devices:
1. Hold the end of the hand-held transmitter about 3 to 8 cm
(1 to 3 in) away from the
Universal Remote system
buttons while keeping the
indicator light in view. The
hand-held transmitter was
supplied by the manufacturer
of the garage door opener
receiver (motor-head unit). 2. At the same time, press
and hold both the hand-held
transmitter button and one
of the three Universal Remote
system buttons to be used to
operate the garage door. Do not
release the Universal Remote
system button or the hand-held
transmitter button until the
indicator light changes from
a slowly to a rapidly flashing
light. You now may release
both buttons.
Some entry gates and garage
door openers may require
substitution of Step 2 with
the procedure noted in “Gate
Operator and Canadian
Programming” later in this
section.

Gate Operator and Canadian
Programming
If you have questions or need help
programming the Universal Remote
system, call 1‐800‐355‐3515 or go
to www.homelink.com.
Canadian radio-frequency laws
require transmitter signals to time
out or quit after several seconds of
transmission. This may not be long
enough for the Universal Remote
system to pick up the signal during
programming. Similarly, some U.S.
gate operators are manufactured to
time out in the same manner.If you live in Canada, or you are
having difficulty programming
a gate operator or garage door
opener by using the
“Programming
the Universal Remote System”
procedures, regardless of where
you live, replace Step 2 under
“Programming the Universal Remote
System” with the following:
Continue to press and hold
the Universal Remote system
button while you press and
release every two seconds (cycle)
the hand-held transmitter button
until the frequency signal has
been successfully accepted by
the Universal Remote system.
The Universal Remote system
indicator light will flash slowly at
first and then rapidly. Proceed with
Step 3 under “Programming the
Universal Remote System” to
complete.
Universal Remote System
Operation
Using the Universal Remote
System
Press and hold the appropriate
Universal Remote system
button for at least half of a second.
The indicator light will come on
while the signal is being transmitted.
Erasing Universal Remote
System Buttons
All programmed buttons should be
erased when the vehicle is sold or
the lease ends.
To erase all programmed buttons
on the Universal Remote system
device:
1. Press and hold down the two outside buttons until the
indicator light begins to flash.
This should take about
10 seconds.
2. Release both buttons.

6-4 Lighting
Adaptive Forward
Lighting (AFL)
The Adaptive Forward Lighting
System (AFL) pivots the headlamps
horizontally to provide greater
road illumination while turning.
To enable AFL, set the exterior
lamp switch to the AUTO position.
Moving the switch out of the AUTO
position deactivates the system.
AFL operates when the vehicle
speed is greater than 3 km/h
(2 mph). AFL does not operate
when the transmission is in
R (Reverse). AFL is not immediately
operable after starting the vehicle;
driving a short distance is required
to calibrate the AFL. SeeExterior
Lamp Controls on page 6‑1.
Hazard Warning Flashers
|
Hazard Warning Flasher:
Press this button located on the
instrument panel below the climate
control system, to make the front
and rear turn signal lamps flash
on and off. Press again to turn the
flashers off.
The hazard warning flashers turn on
automatically if the airbags deploy.
Turn and Lane-Change
Signals
Move the lever all the way up or
down to signal a turn. An arrow on the instrument panel
cluster flashes in the direction of the
turn or lane change.
Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the lane
change is completed. If the lever is
briefly pressed and released, the
turn signal flashes three times.
The turn and lane‐change signal
can be turned off manually by
moving the lever back to its
original position.
If after signaling a turn or lane
change the arrow flashes rapidly
or does not come on, a signal bulb
might be burned out.
Have the bulbs replaced. If the bulb
is not burned out, check the fuse.
See
Fuses and Circuit Breakers on
page 10‑39.

Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTires on
page 10‑46.
.Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention
to your surroundings while driving.
If you become tired or sleepy, find
a safe place to park the vehicle
and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep interior temperature cool.
.Keep your eyes moving —scan
the road ahead and to the sides.
.Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{WARNING
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.

Driving and Operating 9-11
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine
runs faster than the idle speed.
This keeps the battery charged to
restart the vehicle and to signal for
help with the headlamps. Do this
as little as possible to save fuel.If the Vehicle is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method.
{WARNING
If the vehicle's tires spin at high
speed, they can explode, and
you or others could be injured.
The vehicle can overheat,
causing an engine compartment
fire or other damage. Spin the
wheels as little as possible and
avoid going above 55 km/h
(35 mph).
For information about using tire
chains on the vehicle, see Tire
Chains on page 10‑69.
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around
the front wheels. Turn off any
traction system. Shift back and
forth between R (Reverse) and a
forward gear, spinning the wheels
as little as possible. To prevent
transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the transmission is in gear.
Slowly spinning the wheels in the
forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not
get the vehicle out after a few tries,
it might need to be towed out.
If the vehicle does need to be
towed out, see Towing the Vehicle
on page 10‑89.

Black plate (17,1)Buick LaCrosse Owner Manual - 2011
Driving and Operating 9-17
Vehicle speeds above
110 km/h (68 mph) should
be limited to five minutes
per use.
.Avoid making hard stops
for the first 322 km (200 mi)
or so. During this time the
new brake linings are not
yet broken in. Hard stops
with new linings can mean
premature wear and earlier
replacement. Follow this
breaking-in guideline every
time you get new brake
linings.
.Do not tow a trailer during
break-in. SeeDriving
Characteristics and Towing
Tips on page 9‑56 for the
trailer towing capabilities
of your vehicle and more
information.
Following break‐in, engine
speed and load can be gradually
increased.
Ignition Positions
(Key Access)
The ignition switch has four different
positions.
Notice: Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct
key, make sure it is all the way in,
and turn it only with your hand.
If the key cannot be turned by
hand, see your dealer. The key must be fully extended to
start the vehicle.
To shift out of P (Park), turn the
ignition to ON/RUN and apply the
brake pedal.
A (STOPPING THE ENGINE/
LOCK/OFF):
When the vehicle is
stopped, turn the ignition switch to
LOCK/OFF to turn the engine off.
Retained Accessory Power (RAP)
will remain active. See Retained
Accessory Power (RAP) on
page 9‑24 for more information.
This is the only position from
which the key can be removed.
This locks the ignition and automatic
transmission.
Do not turn the engine off when the
vehicle is moving. This will cause
a loss of power assist in the brake
and steering systems and disable
the airbags.
