1-18 In Brief
Universal Remote System
This system, in the overhead
console, provides a way to replace
up to three remote control
transmitters used to activate
devices such as garage door
openers, security systems, and
home automation devices.
Read the instructions completely
before attempting to program the
Universal Remote system. Because
of the steps involved, it may behelpful to have another person
available to assist with programming
the Universal Remote system.
See
Universal Remote System on
page 5-49.
Sunroof
On vehicles with a sunroof, the
switches are located on the
overhead console. The ignition must be in ON/RUN or
ACC/ACCESSORY, or Retained
Accessory Power (RAP) must be
active. See
Retained 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
and release the front of the
switch (4). To stop the sunshade
partway, press the switch a

SeeSunroof on page 2-22.eAssist Features
eAssist®Overview
If the vehicle has eAssist, there are
several additional features that
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 may not shut off. See
Starting the Engine on page 9-18.
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. This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade. See
Hill Start Assist (HSA)
on page 9-33.
Vehicles with eAssist include an
AUTO STOP indicator on the
tachometer. See Instrument Cluster
on page 5-8.
The eAssist system uses a high
voltage battery, which is cooled with
air drawn from the vehicle interior.

dangerous and children or others
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

{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.Press the switch to lower the
window. Pull the switch up to
raise it.
The switches work when the ignition
is in ON/RUN or ACC/
ACCESSORY, or in Retained

Anti-Pinch Feature
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.
If water is seen dripping into the
water drainage system, this is
normal.

3-20 Seats and Restraints
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.
.Seat-mounted side impact
airbags for the second row
outboard passengers.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.

Black plate (21,1)Buick LaCrosse Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
6043609) - 2014 - 2nd Edition - 10/17/13
Seats and Restraints 3-21
{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.
{Warning
Children who are up against,
or very close to, any airbag when
it inflates can be seriously injured
or killed. Always secure children
properly in the vehicle. To read
how, seeOlder Children on
page 3-32 orInfants and Young
Children on page 3-34.
There is an airbag readiness light
on the instrument cluster, which
shows the airbag symbol. The
system checks the airbag electrical
system for malfunctions. The light
tells you if there is an electrical
problem. See Airbag Readiness
Light on page 5-14.
Where Are the Airbags?
The driver frontal airbag is in the
center of the steering wheel.
The front outboard passenger
frontal airbag is in the passenger
side instrument panel.
