Sunroof
On vehicles with a sunroof, the
switches are located on the

ACC/ACCESSORY, or when
Retained Accessory Power (RAP) is
active. SeeRetained Accessory
Power (RAP) on page 9‑24.
Vent: Press the rear of the
switch (2) to the first detent to vent
the sunroof. Press the front of the
switch (1) to the second detent to
close the sunroof. Express-open/Express-close:
To
express-open the sunroof, fully
press and release the rear of the
switch (2). To express-close, fully
press and release the front of the
switch (1). To stop the sunroof
partway, press either switch a
second time.
The sunshade opens automatically
with the sunroof.
To express-open the sunshade, fully
press and release the rear of the
switch (3). To stop the sunshade
partway, press the switch a second
time. To express-close, fully press

See Sunroof on page 2‑19.
eAssist Features
eAssist®Overview
If the vehicle has eAssist, there are
several additional features which
contribute to increased efficiency.
Vehicles with eAssist have an
automatic engine start/stop feature.
This feature saves fuel by shutting
the engine off when the vehicle is
stopped. When the engine shuts off
automatically, all the accessories
will continue to operate normally. In
very hot or cold conditions, the
engine will only shut off
automatically part of the time. See
Starting the Engine on page 9‑19.
There are two air conditioning
settings available. The comfort
setting maximizes cabin comfort.
The eco setting maximizes
efficiency allowing more frequent,
and longer engine stops than the
comfort setting. See Dual Automatic
Climate Control System on
page 8‑1.

could be seriously injured or
killed. They could operate the
power window or other controls or
make the vehicle move. The
windows will function with the key
in the ignition or with the RKE

Adjust this mirror for a clear view of
the area behind the vehicle. Hold
the mirror in the center to move it
up, down, or side to side. To reduce
headlamp glare from behind, push
the tab forward for daytime and pull
it for nighttime use.
Cleaning the Mirror
Do not spray glass cleaner directly
on the mirror. Use a soft towel
dampened with water.
Windows
{WARNING
Never leave a child, a helpless
adult, or a pet alone in a vehicle,
especially with the windows
closed in warm or hot weather.
They can be overcome by the
extreme heat and suffer
permanent injuries or even death
from heat stroke.
The vehicle aerodynamics are
designed to improve fuel economy
performance. This may result in a
pulsing sound when either rear
window is down and the front
windows are up. To reduce the
sound, open either a front window
or the sunroof, if equipped.
Power Windows
{WARNING
Children could be seriously
injured or killed if caught in the
path of a closing window. Never
leave keys in a vehicle with
children. When there are children
in the rear seat, use the window
lockout button to prevent
operation of the windows. See
Keys on page 2‑1.

Pull the sun visor down to block
glare. Detach the sun visor from the
center mount to pivot to the side
window, or to extend along the rod,
if available.

If an object is in the path of the
sunroof while it is closing, the
anti-pinch feature will detect the
object and stop the sunroof from
closing at the point of the
obstruction. The sunroof and
sunshade will then return to the
open or vent position. To close the
sunroof once the obstruction has
been removed, refer to
"Express-Open/Express-Close"
earlier in this section.
Dirt and debris may collect on the
sunroof seal or in the track. This
could cause issues with sunroof
operation and noise. It could also
plug the water drainage system. Periodically open the sunroof and
remove any obstacles or loose
debris. Wipe the sunroof seal and
roof sealing area using a clean
cloth, mild soap, and water. Do not
remove grease from the sunroof.

Replacing Safety Belt
System Parts after a
Crash
{WARNING
A crash can damage the safety
belt system in the vehicle.
A damaged safety belt system
may not properly protect the
person using it, resulting in
serious injury or even death in a
crash. To help make sure the
safety belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.
After a minor crash, replacement of
safety belts may not be necessary.
But the safety belt assemblies that
were used during any crash may
have been stressed or damaged. See your dealer to have the safety
belt assemblies inspected or
replaced.
New parts and repairs may be
necessary even if the safety belt
system was not being used at the
time of the crash.
Have the safety belt pretensioners
checked if the vehicle has been in a
crash, or if the airbag readiness light
stays on after you start the vehicle
or while you are driving. See
Airbag
Readiness Light on page 5‑14.
Airbag System
The vehicle has the following
airbags:
.A frontal airbag for the driver.
.A frontal airbag for the front
outboard passenger.
.A seat-mounted side impact
airbag for the driver.
.A seat-mounted side impact
airbag for the front outboard
passenger.
.A roof-rail airbag for the driver
and the passenger seated
directly behind the driver.
.A roof-rail airbag for the front
outboard passenger and the
passenger seated directly
behind the front outboard
passenger.
The vehicle may have the following
airbags:
.Seat-mounted side impact
airbags for the second row
outboard passengers.

Black plate (20,1)Buick LaCrosse Owner Manual - 2013 - crc - 9/7/12
3-20 Seats and Restraints
All of the airbags have the word
AIRBAG embossed on the trim or
on a label near the deployment
opening.
For frontal airbags, the word
AIRBAG is on the center of the
steering wheel for the driver and on
the instrument panel for the front
outboard passenger.
For seat-mounted side impact
airbags, the word AIRBAG is on the
side of the seatback closest to
the door.
For roof-rail airbags, the word
AIRBAG is on the ceiling or trim.
Airbags are designed to supplement
the protection provided by safety
belts. Even though today's airbags
are also designed to help reduce
the risk of injury from the force of an
inflating bag, all airbags must inflate
very quickly to do their job.Here are the most important things
to know about the airbag system:
{WARNING
You can be severely injured or
killed in a crash if you are not
wearing your safety belt, even
with airbags. Airbags are
designed to work with safety
belts, not replace them. Also,
airbags are not designed to inflate
in every crash. In some crashes
safety belts are the only restraint.
See
When Should an Airbag
Inflate? on page 3‑23.
Wearing your safety belt during a
crash helps reduce the chance of
hitting things inside the vehicle or
being ejected from it. Airbags are
“supplemental restraints” to the
safety belts. Everyone in the
vehicle should wear a safety belt
properly, whether or not there is
an airbag for that person.
{WARNING
Because airbags inflate with great
force and faster than the blink of
an eye, anyone who is up
against, or very close to any
airbag when it inflates can be
seriously injured or killed. Do not
sit unnecessarily close to any
airbag, as you would be if sitting
on the edge of the seat or leaning
forward. Safety belts help keep
you in position before and during
a crash. Always wear a safety
belt, even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle.
Occupants should not lean on or
sleep against the door or side
windows in seating positions with
seat-mounted side impact airbags
and/or roof-rail airbags.

3-22 Seats and Restraints
Driver Side Shown, PassengerSide Similar
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.
