BUICK LACROSSE 2008 Owner's Manual

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

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-5. Poor fuel quality causes
the engine not to run as efficiently as designed. You
might notice this as stalling after start-up, stalling when
you put the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration — these
conditions might go away once the engine is warmed up.
This will be detected by the system and cause the light to
turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer/retailer can check the vehicle. Your
dealer/retailer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that might have developed.Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection
could prevent you from getting a vehicle registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the check
engine light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced the battery or if the
battery has 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 you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your dealer/retailer can prepare the
vehicle for inspection.

Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be covered
by your warranty. Always follow the maintenance
schedule in this manual for changing engine oil.
This light will come on
briey when you start your
engine as a check to be
sure it works. If it does not,
have your vehicle
serviced.
If the light comes on and stays on, it means that oil is not
owing through your engine properly. You could be low
on oil and you might have some other system problem.
Change Engine Oil Light
If this light comes on, it
means that service is
required for your vehicle.
SeeScheduled Maintenance on page 6-4andEngine

Cruise Control Light
This light comes on
whenever you set the
cruise control.
The light goes out when the cruise control is turned off.
SeeCruise Control on page 3-10for more information.
Reduced Engine Power Light
If the reduced engine
power light is on, a chime
will sound and a
noticeable reduction in the
vehicle’s performance
may occur.If the reduced engine power light is on, but there is no
reduction in performance, proceed to your destination.
The performance may be reduced the next time
the vehicle is driven. The vehicle may be driven at a
reduced speed while the reduced engine power light is
on, but acceleration and speed may be reduced.
Anytime the reduced engine power light stays on, the
vehicle should be taken to an authorized GM dealer as
soon as possible for service.
Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.
SeeHeadlamp High/Low-Beam Changer on page 3-8
for more information.

Service Vehicle Soon Light
For vehicles with this light,
it will come on if a
condition exists that may
require the vehicle to
be taken in for service.
If the light comes on, see your dealer/retailer for service
as soon as possible.
Fuel Gage
The fuel gage indicates
about how much fuel is left
in the fuel tank when the
ignition is on.
When the indicator nears empty, there is still a little fuel
left, but you should get more fuel soon.Here are four things that some owners ask about.
All these things are normal and do not indicate that
anything is wrong with the fuel gage:
At the gas station, the pump shuts off before the
gage reads full.
It takes more, or less, fuel to ll up than the gage
reads. For example, the gage reads half full, but
it took more, or less, than half of the tank’s capacity
to ll it.
The gage pointer may move while cornering,
braking or accelerating.
The gage may not indicate empty when the ignition
is turned off.
Low Fuel Warning Light
Your vehicle may have a low fuel light. It is a circle
located on the fuel gage and will come on and a chime
will sound periodically when the vehicle is low on fuel.
The light will go off when fuel is added to the fuel tank.
It will also come on for a few seconds when the ignition
is turned on as a check to indicate it is working. If it
does not come on then, have it xed.
For vehicles with a Driver Information Center (DIC), a
LOW FUEL message will appear. SeeDIC Warnings
and Messages on page 3-58for more information.

Check Gas Cap Light
If your vehicle has this
light, it will come on if your
gas cap is not securely
fastened.
SeeMalfunction Indicator Lamp on page 3-42for more
information.
Driver Information Center (DIC)
Your vehicle may have a Driver Information Center (DIC).
All messages will appear in the DIC display located in
the instrument panel cluster, below the speedometer.
The DIC buttons are located on the center of the
instrument panel, below the center outlets.
The DIC comes on when the ignition is on. After a short
delay, the uplevel DIC will display the WELCOME
DRIVER (1 or 2) if a personalized key 1 or 2 is used,
and then the information that was last displayed before
the engine was turned off.The base level DIC displays the odometer and trip
odometers only.
The uplevel DIC displays the odometer, trip odometers,
fuel economy, trip computer, vehicle system, and
compass display information. It also displays warning
messages if a system problem is detected. In addition,
the uplevel DIC displays phone numbers that are
called using the OnStar
®system, if equipped. See
OnStar®System on page 2-43.
The outside air temperature automatically appears in
the bottom right corner of the uplevel DIC display when
viewing the trip/odometer screens, fuel screens and
some of the gages screens. If the outside air
temperature is at or below 37°F (3°C), the temperature
reading will toggle between displaying the outside
temperature and the word ICE for two minutes. If there
is a problem with the system that controls the
temperature display, the letters OC (open circuit) or SC
(short circuit) will appear on the display. If this occurs,
have the vehicle serviced by your dealer/retailer.
The uplevel DIC also allows some features to be
customized or personalized. SeeDIC Vehicle
Personalization on page 3-76for more information.
