2005 BUICK LACROSSE stop start

Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light will come
on when your engine is
started and may stay on
for several seconds. That
is normal.
If the ABS warning light comes on and stays on, there
may be a problem with the anti-lock portion of the brake
system. If the brake system warning light is not on,
you still have brakes, but you do not have anti-lock
brakes. SeeBrake System Warning Light on page 3-36.
If the light stays on, turn the ignition to OFF. If the
light comes on when you are driving, stop as soon as
possible and turn the ignition off. Then start the
engine again to reset the system. If the 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, you still have brakes, but you do
not have anti-lock brakes. If the regular brake system
warning light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See
Brake System Warning Light on page 3-36.
Traction Control System (TCS)
Warning Light
If the TC (traction control)
warning light comes on
and stays on, there may be
a problem with the
traction control system
and, if equipped, the
StabiliTrak
®system.
The TC (traction control) warning light will come on
briey when you turn the ignition to RUN. If it does not
come on then, have it xed so it will be ready to
warn you if there is a problem.
The light will also come on if you turn the traction
control system off using the TC (traction control) on/off
button located near the shift lever.
If the TC (traction control) 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 equipped, the StabiliTrak
®system
inspected as soon as possible. SeeTraction Control
System (TCS) on page 4-8andStabiliTrak
®System on
page 4-9for more information.

Engine Coolant Temperature
Warning Light
This light tells you that
your engine is very hot.
This light will come on when you rst start the vehicle
as a check to let you know that the light is working. It will
go out after a few seconds. If the light does not come
on, the bulb may be burned out. See your GM dealer to
have it corrected.
If the light does not go out or if the light comes on and
stays on while you are driving, your vehicle may
have a problem with the cooling system. You should
stop the vehicle and turn off the engine as soon
as possible to avoid damage to the engine. A warning
chime will sound when this light is on, also.
SeeEngine Overheating on page 5-24.
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 5-24.

This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
If the Light is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possibleIf 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 your vehicle.
Turn the key 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
for service as soon as possible.
If the Light Is On Steady
You may 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 will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
3-40

Oil Pressure Light
If the vehicle has an oil
problem, this light may
stay on after the engine is
started, or come on
while you are driving.
This light indicates that oil is not going through the
engine quickly enough to keep it lubricated. The engine
could be low on oil or could have some other oil
problem. Have it xed right away.
The oil light could also come on in the following
situations:
The light will come on briey when the ignition is
turned on to show that it is working properly. If it
does not come on with the ignition on, there may be
a problem with the fuse or bulb. Have it xed
right away.
Sometimes when the engine is idling at a stop, a
chime will sound and the light may blink on and
off. This is normal.
{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.
