2006 BUICK LUCERNE warning light

Fuel Gage
The fuel gage shows about how much fuel is in your
tank. It works only when the ignition is on. When the
indicator moves to the edge of the low fuel warning
band, the low fuel warning light will come on and
a chime will sound. You still have a little fuel left, but
you need to get more fuel right away.Here are some things that some owners ask about.
None of these show a problem with your fuel gage:
At the service station, the gas pump shuts off before
the gage reads full.
It takes more (or less) fuel to ll up than the gage
indicated. For example, the gage may have
indicated half full, but it took more (or less) than
half the tank’s capacity to ll it.
The gage moves up a little when you turn a corner,
speed up or make a hard stop.
The gage does not go back to empty when you
turn off the ignition.

DIC Warnings and Messages
Messages are displayed on the DIC to notify the driver
that the status of the vehicle has changed and that
some action may be needed by the driver to correct the
condition. Multiple messages may appear one after
another. Some messages may not require immediate
action, but you can press the set/reset button to
acknowledge that you received the message and clear it
from the DIC display. Pressing any of the DIC buttons
will also acknowledge and clear any messages.
Some messages cannot be cleared from the DIC display
because they are more urgent. These messages
require action before they can be cleared. You should
take any messages that appear on the display seriously
and remember that clearing the messages will only
make the messages disappear, not correct the problem.
The following are the possible messages that can be
displayed and some information about them.

This message will display when the automatic
headlamps are turned off.
AUTOMATIC LIGHT CONTROL ON

Control of a Vehicle
You have three systems that make your vehicle go where
you want it to go. They are the brakes, the steering, and
the accelerator. All three systems have to do their work at
the places where the tires meet the road.
Sometimes, as when you are driving on snow or ice, it
is easy to ask more of those control systems than
the tires and road can provide. That means you can
lose control of your vehicle. SeeTraction Control
System (TCS) on page 4-9.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 5-3.
Braking
SeeBrake System Warning Light on page 3-40.
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That is perception time. Then you have to bring up your
foot and do it. That is reaction time.Average reaction time is about three-fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds or
more with another. Age, physical condition, alertness,
coordination, and eyesight all play a part. So do alcohol,
drugs, and frustration. But even in three-fourths of a
second, a vehicle moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of distance in an
emergency, so keeping enough space between
your vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement
or gravel; the condition of the road, whether it is
wet, dry, or icy; tire tread; the condition of your brakes;
the weight of the vehicle; and the amount of brake
force applied.
Avoid needless heavy braking. Some people drive in
spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
