2007 BUICK LUCERNE tow

Raise or lower the lever until the arrow starts to
ash to signal a lane change. Hold it there until the
lane change is complete. If you momentarily press
and release the lever, the turn signal will ash
three times.
If the arrows ash very fast as you signal a turn or a
lane change, a signal bulb may be burned out and
other drivers will not see your turn signal. If a bulb is
burned out, replace it to help avoid an accident.
If the arrows do not go on at all when you signal
a turn, check the fuse. SeeFuses and Circuit
Breakers on page 428.
Turn Signal On Chime
If your turn signal is left on for more than
0.8 miles (1.3 km), a chime will sound at each
ash of the turn signal. To turn off the chime,
move the turn signal lever to the off position.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to
high beam, push the turn signal lever away from
you. To change from high beam to low beam,
pull the turn signal lever toward you.
While the high beams
are on, this light located
on the instrument
panel cluster will
also be on.

Flash-to-Pass
This feature lets you use the high-beam headlamps
to signal the driver in front of you that you want to
pass. It works even if your headlamps are off.
Pull the turn signal lever toward you briey to
ash-to-pass.
If the headlamps are off or on low beam, the
high-beam headlamps will turn on. They will stay on
as long as you hold the lever toward you and the
high-beam indicator on the instrument panel cluster
will come on.
Windshield Wipers
You control the windshield wipers by turning the
band with the wiper symbol on it.
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. For more wipe
cycles, hold the band longer on mist.
6(Delay):Turn the band to choose the delay time
between wipe cycles. The wiper speed can be set
for a long or short delay between wipes. The closer
the band is set to the top of the lever, the shorter
the delay.
6(Low Speed):Turn the band away from
you to the rst solid band past the delay settings
for steady wiping at low speed.
1(High Speed):For high-speed wiping, turn
the band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band to off.
Clear ice and snow from the wiper blades before
using them. If they are frozen to the windshield,
carefully loosen or thaw them. If the blades
become worn or damaged, replace with new
blades or blade inserts.
Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools. Clear
away snow or ice to prevent an overload.
Your vehicle has wiper-activated headlamps. After
the windshield wipers have completed eight
wipe cycles within four minutes, the headlamps
automatically turn on. SeeWiper Activated
Headlamps on page 171for more information.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop you. For good braking,
though, you need both parts working well.
If the warning light comes on, there is a brake
problem. Have your brake system inspected
right away.
This light should come on briey when you turn the
ignition key to RUN. If it does not come on then,
have it xed so it will be ready to warn you if there’s
a problem.When the ignition is on, the brake system warning
light will also come on when you set your parking
brake. The light will stay on if your parking brake
does not release fully. If it stays on after your
parking brake is fully released, it means you
have a brake problem.
If the light comes on while you are driving, pull off
the road and stop carefully. You may notice that the
pedal is harder to push, or the pedal may go closer
to the oor. It may take longer to stop. If the light is
still on, have the vehicle towed for service. See
Towing Your Vehicle on page 313.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.United StatesCanada

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 351for more information.
Notice:Driving with the engine coolant
temperature warning light on could cause your
vehicle to overheat. SeeEngine Overheating
on page 351. 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
This gage shows the engine coolant temperature. If
the pointer moves towards the H (United States) or
shaded in thermostat symbol area (Canada), the
engine is too hot.
A temperature indicator light will turn on and a
chime will sound.
If you have been operating your vehicle under
normal driving conditions, and the temperature
indicator light comes on, you should pull off
the road, stop your vehicle and turn off the
engine as soon as possible.

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 330.
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.

Rocking Your Vehicle to Get It Out
First, turn the steering wheel left and right.
That will clear the area around the front wheels.
If your vehicle has traction control, you should turn
the traction control system off. SeeTraction
Control System (TCS) on page 283. Then shift
back and forth between REVERSE (R) and
a forward gear, spinning the wheels as little as
possible. Release the accelerator pedal while you
shift, and press lightly on the accelerator pedal
when the transaxle is in gear. By slowly spinning
the wheels in the forward and reverse directions,
you will cause a rocking motion that may free
your vehicle. If that does not get your vehicle out
after a few tries, it may need to be towed out.
If your vehicle does need to be towed out,
seeTowing Your Vehicle on page 313.
Loading Your Vehicle
It is very important to know how much weight
your vehicle can carry. This weight is called the
vehicle capacity weight and includes the weight of
all occupants, cargo, and all nonfactory-installed
options. Two labels on your vehicle show how
much weight it may properly carry; the Tire
and Loading Information label and the
Certication label.
{CAUTION:
Do not load your vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do,
parts on your vehicle can break, and it
can change the way your vehicle handles.
These could cause you to lose control
and crash. Also, overloading can shorten
the life of your vehicle.
