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

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.

Engine Coolant
Temperature Gauge
Metric
English
This gauge shows the engine
coolant temperature.
If the gauge pointer moves toward
the shaded area, the engine is
too hot.
In eAssist vehicles, the engine
coolant warning light comes on
when the engine is too hot. See
Engine Coolant Temperature
Warning Light on page 5‑22 in this
section. This reading indicates the same
thing as the warning light. It means
that the engine coolant has
overheated. If the vehicle has been
operating under normal driving
conditions, pull off the road, stop the
vehicle, and turn off the engine as
soon as possible. See
Engine
Overheating on page 10‑21 for more
information.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
There is a driver safety belt
reminder light on the instrument
cluster.
When the vehicle is started, this
light flashes and a chime may come
on to remind the driver to fasten

Black plate (17,1)Buick LaCrosse Owner Manual - 2013 - crc - 9/7/12
Instruments and Controls 5-17
This light comes on during a
malfunction in one of two ways:
Light Flashing:A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
To prevent more serious damage to
the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If the vehicle is towing a trailer,
reduce the amount of cargo
being hauled as soon as it is
possible.
If the light continues to flash, find a
safe place to stop and park the
vehicle. Turn the vehicle off, wait at
least 10 seconds, and restart the
engine. If the light is still flashing,
follow the previous steps and see
your dealer for service as soon as
possible. Light On Steady:
An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
The following may correct an
emissions control system
malfunction:
.Check that the fuel cap is fully
installed. See Filling the Tank on
page 9‑50. The diagnostic
system can determine if the fuel
cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn the
light off.
.Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration, or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these conditions
occurs, change the fuel brand used.
It may require at least one full tank
of the proper fuel to turn the light off.
See Recommended Fuel on
page 9‑47.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.
Emissions Inspection and
Maintenance Programs
Depending on where you live, your
vehicle may be required to
participate in an emission control
system inspection and maintenance
program. For the inspection, the
emission system test equipment will
likely connect to the vehicle's Data
Link Connector (DLC).

Black plate (18,1)Buick LaCrosse Owner Manual - 2013 - crc - 9/7/12
5-18 Instruments and Controls
The DLC is under the instrument
panel next to the steering wheel.
See your dealer if assistance is
needed.
The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on while the vehicle is running.
The vehicle is in ON/RUN for
keyed access, or service only
mode for keyless access and the
malfunction indicator lamp does
not come on. See your dealer for
assistance in verifying proper
operation of the malfunction
indicator lamp.
.The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed. Thevehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or run
down. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer
can prepare the vehicle for
inspection.
Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have your brake
system inspected right away.
MetricEnglish
With antilock brakes, this light
should come on when the vehicle is
placed in START. If it does not, have
the vehicle serviced by your dealer.
If the light comes on while driving,
pull off the road and stop carefully.
The pedal may be harder to push or
it can go closer to the floor. It may
take longer to stop. Try turning off
and restarting the vehicle one or two
times. If the light is still on, have the
vehicle towed for service. See
Antilock Brake System (ABS)
Warning Light on page 5‑19 and
Towing the Vehicle on page 10‑90.

{WARNING
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
Electric Parking Brake
Light
MetricEnglish
For vehicles with the Electric
Parking Brake (EPB), the parking
brake status light comes on when the parking brake is applied. If the
light continues flashing after the
parking brake is released, or while
driving, there is a problem with the
Electric Parking Brake system.
A message may also display in the
Driver Information Center (DIC).
See
Brake System Messages on
page 5‑33 for more information.
If the light does not come on,
or remains flashing, see your dealer.
For vehicles with the Electric
Parking Brake (EPB), the parking
brake warning light should come on
briefly when ignition is placed in ON/
RUN. If it does not come on, then
have it fixed so it will be ready to
warn if there is a problem. If this light comes on, there is a
problem with a system on the
vehicle that is causing the parking
brake system to work at a reduced
level. The vehicle can still be driven,
but should be taken to a dealer as
soon as possible. See
Parking
Brake on page 9‑32 for more
information.
For vehicles with the uplevel or
eAssist cluster, this telltale displays
in the Driver Information Center
(DIC) screen.
