2006 CADILLAC STS engine

Cruise Control Light
This light comes on
whenever you set your
cruise control.
The light will go out when the cruise control is turned
off. SeeCruise Control on page 3-16andAdaptive
Cruise Control on page 3-19for more information.
Highbeam On Light
This light comes on
whenever the high-beam
headlamps are on.
See “Intellibeam™ Intelligent High-Beam Headlamp
Control System” underHeadlamps on page 3-31
andHeadlamp High/Low-Beam Changer on page 3-8
for more information.
Fuel Gage
The fuel gage shows
approximately how much
fuel is in the tank. It
works only when the
engine is on.
If the fuel supply gets low, the Fuel Level Low message
will appear on the DIC and a single chime will sound. See
DIC Warnings and Messages on page 3-79for more
information.
Here are a few concerns some owners have had about
the fuel gage. All of these situations are normal and
do not indicate that anything is wrong with the fuel gage:
At the gas station the gas pump shuts off before
the gage reads full.
The gage may change when you turn, stop quickly
or accelerate quickly.
It takes a little more or less fuel to ll the tank than
the gage indicated. For example, the gage may have
indicated that the tank was half full, but it actually
took a little more or less than half the tank’s capacity
to ll the tank.

Driver Information Center (DIC)
The Driver Information Center (DIC) gives you the
status of many of your vehicle’s systems. The DIC is
also used to display warning/status messages. All
messages will appear in the DIC display located at the
bottom of the instrument panel cluster, below the
tachometer and speedometer. The DIC buttons are
located on the instrument panel, to the left of the
steering wheel.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the current driver and the
information that was last displayed before the engine
was turned off.
The top line of the DIC display shows the vehicle system
information and the warning/status messages. The
bottom line of the DIC display shows either the odometer,
the trip odometer A or the trip odometer B information on
the left side. Only one odometer can appear at a time.
See “Trip Information” underDIC Controls and Displays
on page 3-74for information on changing the display to
show the odometer or trip odometer information. The
bottom line of the DIC display also shows the outside
temperature on the right side and the shift lever position
indicator in the center.SeeAutomatic Transmission Operation (5-Speed
Automatic) on page 2-28orAutomatic Transmission
Operation (6-Speed Automatic) on page 2-32for more
information on the shift lever positions.
When the sport mode is active, an S will appear next to
the shift position indicator on the center of the DIC
display. When the manual mode is active, an M will
appear on the DIC display. When the normal mode is
active, only the shift position indicator will appear. While
the Driver Shift Control (DSC) feature is active, the DIC
will change to show the selected gear. See “Driver Shift
Control (DSC)” underAutomatic Transmission Operation
(5-Speed Automatic) on page 2-28orAutomatic
Transmission Operation (6-Speed Automatic) on
page 2-32for more information.
If a problem is detected, a warning message will appear
on the display. Be sure to take any message that
appears on the display seriously and remember that
clearing the message will only make the message
disappear, not correct the problem.
