2008 BUICK LACROSSE stop start

Turn and Lane-Change Signals
To signal a turn, move the lever up or down. The lever
returns to its original position when the turn is completed.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
To signal a lane change, raise or lower the lever until
the arrow starts to ash. Hold it there until the lane
change is completed. The lever will return to its original
position when released.
Arrows that ash rapidly when signaling for a turn or
lane change, or that fail to work, may indicate a
burned-out signal bulb or fuse. Other drivers will not see
the signal. SeeTaillamps, Turn Signal, Sidemarker,
Stoplamps and Back-up Lamps on page 5-59for turn
signal bulb replacement procedures. Also seeFuses and
Circuit Breakers on page 5-109for location of fuses.
A chime will sound if the turn signal is left on for more
than 3/4 mile (1.2 km).
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high beam,
push the turn signal/multifunction lever away from you.
This light comes on in the
instrument panel cluster if
the high beam lamps
are turned on while the
ignition is in ON/RUN.
To change the headlamps from high beam to low beam,
pull the turn signal lever toward you.
Flash-to-Pass
This feature lets you use your high-beam headlamps
momentarily to signal a driver in front of you that
you want to pass.
To use it, pull the turn signal/multifunction lever toward
you until the high-beam headlamps come on, then
release the lever to turn them off.

Windshield Wipers
Clear ice and snow from the wiper blades before using
them. If they are frozen to the windshield, gently
loosen or thaw them. Damaged wiper blades may not
clear the windshield well, making it harder to see
and drive safely. If the blades do become damaged,
install new blades or blade inserts. For more information,
seeWindshield Wiper Blade Replacement on page 5-62.
Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools down.
Clear away snow or ice to prevent an overload.
Turn the band with the wiper symbol to control the
windshield wipers.
8(Mist):Turn the band to mist for a single wiping
cycle. Hold it there until the wipers start. Then let
go. The wipers stop after one wipe. Hold the band on
mist longer, for more wipe cycles.
9(Off):To stop the wipers, move the band to off.
6(Delay):Turn the band to adjust the delay time. The
delay between wiping cycles becomes shorter as
the band is moved to the top of the lever. This can be
very useful in light rain or snow.
6(Low Speed):Turn the band away from you to
the rst solid band past the delay settings, for steady
wiping at low speed.
?(High Speed):Turn the band further, to the
second solid band past the delay settings, for
high-speed wiping.
Windshield Washer
LQ(Washer Fluid):There is a paddle marked
with the windshield washer symbol at the top of
the multifunction lever. To spray washer uid on the
windshield, push the paddle. The wipers will clear
the window and then either stop or return to your
preset speed.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.

Antilock Brake System
Warning Light
For vehicles with
the Antilock Brake
System (ABS), this light
comes on briey when the
engine is started.
That is normal. If the light does not come on then,
have it xed so it will be ready to warn you if there
is a problem.
If the ABS light stays on, turn the ignition off, if the light
comes on when you are driving, stop as soon as it is
safely possible and turn the ignition off. Then start
the engine again to reset the system. If the ABS light
still stays on, or comes on again while you are driving,
your vehicle needs service. If the regular brake
system warning light is not on, your vehicle still has
brakes, but not antilock brakes. If the regular brake
system warning light is also on, your vehicle does not
have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 3-37.For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages on page 3-58for all
brake related DIC messages.Traction Control System (TCS)
Warning Light
Your vehicle has a Traction
Control System (TCS)
warning light.
If this warning light comes on and stays on, there may
be a problem with the TCS and, if your vehicle has
this feature, the StabiliTrak
®system.
3-38

The TCS warning light will come on briey when the
engine is started. If it does not come on then, have
it xed so it will be ready to warn you if there is
a problem. This light will also come on when the traction
control button is pressed disabling the system.
If the TCS warning light stays on or comes on while you
are driving, pull off the road as soon as possible and
stop carefully. Try resetting the system by turning
the ignition off then back on. If the light still stays on or
comes back on again while you are driving, your
vehicle needs service. Have the traction control system
and, if your vehicle has this feature, the StabiliTrak
®
system inspected as soon as possible. SeeTraction
Control System (TCS) on page 4-6andStabiliTrak®
System on page 4-8for more information.
Enhanced Traction System
Warning Light
For vehicles with the
Enhanced Traction
System (ETS), this light
may come on for the
following reasons:
If the traction control button located on the center
console is pressed, turning the system off. This
light will come on and stay on. To turn the system
back on, press the button again and the warning
light should turn off. SeeEnhanced Traction
System (ETS) on page 4-7.
If the system is affected by an engine-related
problem, the system will turn off and the warning
light will come on.
If the light comes on and stays on for an extended
period of time when the system is turned on, the vehicle
needs service.
3-39

Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning light
will come on when the
engine has overheated.
If this happens you should pull over and turn off the
engine as soon as possible. SeeEngine Overheating on
page 5-30for more information.
Notice:Driving with the engine coolant temperature
warning light on could cause your vehicle to
overheat. SeeEngine Overheating on page 5-30.
Your vehicle could be damaged, and it might not be
covered by your warranty. Never drive with the
engine coolant temperature warning light on.
This light will also come on briey when starting your
vehicle. If it does not, have your vehicle serviced.
Engine Coolant Temperature Gage
The vehicle has a gage
that shows the engine
coolant temperature.
If the gage pointer moves towards the H, the engine is
too hot.
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. SeeEngine
Overheating on page 5-30.
3-40

Low Coolant Warning Light
If your vehicle has this
light, it comes on briey
when you turn your ignition
on as a bulb check only.
Tire Pressure Light
Your vehicle has a tire
pressure light.
This light comes on briey when the engine is started
and provides information about tire pressures and
the Tire Pressure Monitoring System.
When the Light is Solid
This indicates that one or more of your tires are
signicantly underinated.
A tire pressure message in the Driver Information
Center (DIC), may accompany the light. SeeDIC
Warnings and Messages on page 3-58for more
information. Stop and check your tires as soon as it is
safe to do so. If underinated, inate to the proper
pressure. SeeTires on page 5-63for more information.
When the Light Flashes First and Then
is Solid
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light ashes for about
a minute and stays on solid for the remainder of
the ignition cycle. This sequence will repeat with every
ignition cycle. SeeTire Pressure Monitor System on
page 5-71for more information.
3-41

This light comes on, as a check to show it is working,
when the ignition is turned ON/RUN but the engine is not
running. If the light does not come on, have it repaired.
This light also comes on during a malfunction in
one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions and
could damage the emission control system on your
vehicle. Diagnosis and service might be required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service might be required.
If the Light is Flashing
The following can prevent more serious damage to your
vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops ashing and remains on steady, see “If
the Light Is On Steady” following.If the light continues to ash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the ignition off, wait at least 10 seconds, and restart
the engine. If the light remains on steady, see “If the
Light Is On Steady” following. If the light is still ashing,
follow the previous steps and see your dealer/retailer
for service as soon as possible.
If the Light Is On Steady
You might be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. SeeFilling the Tank on page 5-8. 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.
Did you just drive through a deep puddle of water?
If so, your vehicle’s electrical system might be wet.
The condition is usually corrected when the electrical
system dries out. A few driving trips should turn the
light off.
3-43

There is also a retroactive trip odometer function that
performs the following for each trip odometer:
If the vehicle’s speed has exceeded 3 mph (5 km/h)
during the current ignition cycle, this function will
set the trip odometer to the distance driven
during the current ignition cycle.
If the vehicle’s speed has not exceeded
3 mph (5 km/h), this function will set the trip
odometer to the distance driven during the previous
ignition cycle plus the distance driven during the
current ignition cycle.
Press and hold the set/reset button on vehicles with the
uplevel DIC or the trip/odometer button on vehicles
with the base level DIC for three seconds, then release
the button. The retroactive trip odometer value will
be set into the currently displayed trip odometer.
Time Elapsed (Uplevel Only)
Press the trip/odometer button until TIME ELAPSED :00
displays. This mode is like a stopwatch, in that you
can clock the time it takes to get from one point
to another. Each of the elds for the hours, minutes,
and seconds are two numeric digits.Once TIME ELAPSED :00 is displayed, press the
set/reset button on vehicles with the uplevel DIC to start
the timing feature. Press the set/reset button again to
stop it. If you will be starting and stopping your vehicle,
during a trip for instance, the TIME ELAPSED feature
will automatically start timing where it left off when
you last stopped. To reset it, press and hold the
set/reset button for about 1.5 seconds. The display will
return to zero. Press the trip/odometer button to exit
from the TIME ELAPSED display.
Average Speed (Uplevel Only)
Press the trip/odometer button until AVERAGE SPEED
displays. This mode shows the average speed of
the vehicle in miles per hour (mph) or kilometers per
hour (km/h). This average is calculated based on
the various vehicle speed recorded since the last reset
of this value. To reset the value, press the trip/odometer
button to display AVERAGE SPEED, then press and
hold the set/reset button on vehicles with the uplevel
DIC. The display will return to zero.
