The driver and front outboard
passenger seat-mounted side
impact airbags are in the side of the
seatbacks closest to the door.
The roof-rail airbags for the driver,
front outboard passenger, and
second row outboard passengers
are in the ceiling above the side
windows.Rear Seat Driver Side Shown, Passenger Side Similar
On vehicles with second row
seat-mounted side impact airbags,
they are in the sides of the rear
seatback closest to the door.
{WARNING
If something is between an
occupant and an airbag, the
airbag might not inflate properly
or it might force the object into
that person causing severe injury (Continued)
WARNING (Continued)
or even death. The path of an
inflating airbag must be kept
clear. Do not put anything
between an occupant and an
airbag, and do not attach or put
anything on the steering wheel
hub or on or near any other
airbag covering.
Do not use seat accessories that
block the inflation path of a
seat-mounted side impact airbag.
Never secure anything to the roof
of a vehicle with roof-rail airbags
by routing a rope or tie‐down
through any door or window
opening. If you do, the path of an
inflating roof-rail airbag will be
blocked.

WARNING (Continued)
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps, turn on the
hazard warning flashers, and shut
off the fuel system after the airbags
inflate. You can lock the doors, turn
off the interior lamps, and turn off
the hazard warning flashers by
using the controls for those
features.
{WARNING
A crash severe enough to inflate
the airbags may have also
damaged important functions in
the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage may
also occur from the front outboard
passenger airbag.
.Airbags are designed to inflate
only once. After an airbag
inflates, you will need some new parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for the vehicle covers the need
to replace other parts.
.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See
Vehicle Data
Recording and Privacy on
page 13‑18 andEvent Data
Recorders on page 13‑19.
.Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.

of the retractor to set the lock,
if the vehicle has one, after the
child restraint has been installed.
Notice: Do not let the LATCH
attachments rub against the
vehicle’ s safety belts. This may
damage these parts. If necessary,
move buckled safety belts to
avoid rubbing the LATCH
attachments.
Do not fold the empty rear seat
with a safety belt buckled. This
could damage the safety belt or
the seat. Unbuckle and return the
safety belt to its stowed position,
before folding the seat.
If you need to secure more than one
child restraint in the rear seat, see
Where to Put the Restraint on
page 3‑38.
You cannot secure three child
restraints using the LATCH anchors
in the rear seat at the same time, but you can install two of them.
If you want to do this, install one
LATCH child restraint in the right
rear seating position, and install the
other one either in the left rear
seating position or in the center
seating position. If you need to
install child restraints in both the
center and left rear seating
positions, the one in the center
seating position will need to be
secured using the vehicle safety
belts instead of the LATCH anchors.
Refer to the following illustration to
learn which anchors to use.
There are five lower LATCH anchors
in the rear seat.
.Use anchors 1 and 2 when
installing a child restraint using
LATCH in the right rear seating
position.
.Use anchors 3 and 4 when
installing a child restraint using
LATCH in the center rear seating
position.
.Use anchors 4 and 5 when
installing a child restraint using
LATCH in the left rear seating
position.
Installing child restraints using
LATCH in the center and left rear
seating positions at the same time is
prohibited.
Make sure to attach the child
restraint at the proper anchor
location.

5-4 Instruments and Controls
INT: (Intermittent Wipes):Move
the lever up to INT for intermittent
wipes, then turn the
3INT band
up for more frequent wipes or down
for less frequent wipes.
OFF: Use to turn the wipers off.
8(Mist): For a single wipe, briefly
move the wiper lever down. For
several wipes, hold the wiper
lever down.
n L(Windshield Washer): Pull
the windshield wiper lever toward
you to spray windshield washer fluid
and activate the wipers. The wipers
will continue until the lever is
released or the maximum wash time
is reached. When the windshield
wiper lever is released, additional
wipes may occur depending on how
long the windshield washer had
been activated. See Washer Fluid
on page 10‑24 for information on
filling the windshield washer fluid
reservoir.
{WARNING
In freezing weather, do not use
the washer until the windshield is
warmed. Otherwise the washer
fluid can form ice on the
windshield, blocking your vision.
Clear snow and ice from the wiper
blades and windshield before using
them. If frozen to the windshield,
carefully loosen or thaw them.
Damaged blades should be
replaced. See Wiper Blade
Replacement on page 10‑29.
Heavy snow or ice can overload the
wiper motor.
Wipe Parking
If the ignition is turned to LOCK/
OFF while the wipers are on LO, HI,
or INT, they will immediately stop. If the windshield wiper lever is then
moved to off before the driver door
is opened or within 10 minutes, the
wipers will restart and move to the
base of the windshield.
If the ignition is turned to LOCK/
OFF while the wipers are performing
wipes due to windshield washing,
the wipers continue to run until they
reach the base of the windshield.
Compass
The vehicle may have a compass
display on the Driver Information
Center (DIC). The compass receives
its heading and other information
from the Global Positioning
System (GPS) antenna, StabiliTrak,
and vehicle speed information.
Avoid covering the GPS antenna for
long periods of time with objects
that may interfere with the antenna's
ability to receive a satellite signal.
See
Backglass Antenna on
page 7‑13 andSatellite Radio
Antenna on page 7‑14 for the
location of the vehicle's antennas.

Black plate (5,1)Buick LaCrosse Owner Manual - 2013 - crc - 9/7/12
Instruments and Controls 5-5
The compass system is designed to
operate for a certain number of
miles or degrees of turn before
needing a signal from the GPS
satellites. When the compass
display shows CAL, drive the
vehicle for a short distance in an
open area where it can receive a
GPS signal. The compass system
will automatically determine when
the GPS signal is restored and
provide a heading again. See
Compass Messages on page 5‑33
for more information on the
messages that may be displayed for
the compass.
