2007 CADILLAC STS engine

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 258for 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 inthe center. SeeAutomatic Transmission Operation
on page 116for 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 on page 116for 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.
DIC Controls and Displays
The Driver Information Center (DIC) has different
modes which can be accessed by pressing
the four DIC buttons located on the instrument
panel, to the left of the steering wheel.

BATTERY VOLTAGE HIGH
This symbol appears
with this message.
This message displays when the electrical
charging system is overcharging the battery.
When the system detects that the battery voltage
is above an estimated 16 volts, this message
displays.
To reduce the charging overload, use the vehicle’s
accessories. Turn on the exterior lamps and
radio, set the climate control on AUTO and the fan
speed on the highest setting, and turn the rear
window defogger on.
The normal battery voltage range is
11.5 to 15.5 volts when the engine is running.
You can monitor battery voltage on the DIC
by pressing the information button until you nd
BATTERY VOLTS.
BATTERY VOLTAGE LOW
This symbol appears
with this message.
This message displays when the electrical system
is charging less than 10 volts or the battery has
been drained.
If this message appears immediately after starting
the engine, it is possible that the generator can
still recharge the battery. The battery should
recharge while driving, but may take a few hours
to do so. Consider using an auxiliary charger
to boost the battery after returning home or to a
nal destination. Make sure you follow the
manufacturer’s instructions.
If this message appears while driving or after
starting your vehicle and stays on, have it checked
immediately to determine the cause of this problem.

To help the generator recharge the battery quickly,
you can reduce the load on the electrical system
by turning off the accessories.
The normal battery voltage range is
11.5 to 15.5 volts. You can monitor battery voltage
on the DIC by pressing the information button
until you nd BATTERY VOLTS.
CHANGE ENGINE OIL SOON

been fully tightened. Recheck the fuel cap to
ensure that it is on and tightened properly.
CHECK TIRE PRESSURE
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message displays when the tire
pressure in one of the tires needs to be checked.
SeeDIC Controls and Displays on page 258
for more information on checking your vehicle’s
tire pressures. If a tire pressure message appears
on the DIC, stop as soon as you can. Have the
tire pressures checked and set to those shown on
the Tire Loading Information label. SeeTire
Pressure Monitor System on page 433and
Ination - Tire Pressure on page 431for more
information. If the tire pressure is low, the low tire
pressure warning light comes on. SeeLow Tire
Pressure Warning Light on page 249.

ENGINE COOLANT HOT IDLE ENGINE
Notice:If you drive your vehicle while the
engine is overheating, severe engine damage
may occur. If an overheat warning appears
on the instrument panel cluster and/or DIC,
stop the vehicle as soon as possible. Do not
increase the engine speed above normal idling
speed. SeeEngine Overheating on page 393
for more information.
This symbol appears
with this message.
This message displays when the engine coolant
temperature is too hot. Stop and allow the vehicle
to idle until it cools down. SeeEngine Coolant
Temperature Warning Light on page 251.
SeeOverheated Engine Protection Operating
Mode on page 395for information on driving to a
safe place in an emergency.
ENGINE HOT –
AC (Air Conditioning) OFF
This message displays when the engine coolant
becomes hotter than the normal operating
temperature. SeeEngine Coolant Temperature
Gage on page 251. To avoid added strain on a hot
engine, the air conditioning compressor is
automatically turned off. When the coolant
temperature returns to normal, the air conditioning
compressor turns back on. You can continue to
drive your vehicle.
If this message continues to appear, have the
system repaired by your dealer as soon as
possible to avoid damage to the engine.
269

ENGINE OVERHEATED STOP ENGINE
Notice:If you drive your vehicle while the
engine is overheating, severe engine damage
may occur. If an overheat warning appears
on the instrument panel cluster and/or
DIC, stop the vehicle as soon as possible.
SeeEngine Overheating on page 393for more
information.
This message displays when the engine has
overheated. Immediately look for a safe place to
pull your vehicle over and turn the engine off right
away to avoid severe engine damage. SeeEngine
Overheating on page 393andOverheated Engine

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 this message is on, but acceleration
and speed may be reduced. Anytime this message
stays on, the vehicle should be taken to your
dealer for service as soon as possible.
ENGINE PROTECTION REDUCED
RPM’S (Revolutions Per Minute)
This message displays when your vehicle is in an
overheated engine operating mode. If this
message appears, the vehicle has determined that
continued operation at the existing engine speed
may lead to engine overheating. The vehicle
automatically limits engine RPMs to prevent engine
overheating. You may notice the vehicle upshifting
early or reduced speeds while this message is
displayed. When the engine oil returns to a
safe operating temperature, this message clears
from the DIC and the vehicle returns to normal
operation. Your vehicle does not require service
when this message is displayed.
