2009 CADILLAC STS manual transmission

Driver Shift Control (DSC)
Notice:If you drive the vehicle at high RPMs
without upshifting while using Driver Shift
Control (DSC), you could damage the vehicle.
Always upshift when necessary while using DSC.
Driver Shift Control (DSC) allows you shift an automatic
transmission similar to a manual transmission.
To use the DSC feature:
1. Move the shift lever to the right from D (Drive) into
the DSC area.
When in DSC mode, the
sport symbol will appear
in the Driver Information
Center (DIC).
The vehicle will remain in sport mode if the
shift lever is not moved. Sport mode will shift
automatically but remain in a gear longer then it
would in normal driving mode based on braking
and acceleration.2. Press the shift lever forward to upshift or rearward
to downshift.
When using the DSC
mode, the number
displayed on the Driver
Information Center (DIC)
indicates the gear that
the transmission is in.
SeeDriver Information
Center (DIC) on page 3-72
for more information on
the DIC.
When starting the vehicle from a stopped condition,
only 1 (First) and 2 (Second) gear may be used.
While using the DSC feature the vehicle will have rmer
shifting and increased performance. You can use this for
sport driving or when climbing/descending hills to stay in
gear longer or to down shift for more power or engine
braking.
The transmission will only allow you to shift into
gears appropriate for the vehicle speed and engine
Revolutions Per Minute (RPM). The transmission will
not automatically shift to the next higher gear if the
engine RPM is too high.

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
Operation and Displays on page 3-72for 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 on page 2-30
for 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 2-30for 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 Operation 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.

Parking on Hills
{CAUTION:
Parking the vehicle on a hill with the trailer
attached can be dangerous. If something goes
wrong, the rig could start to move. People can be
injured, and both the vehicle and the trailer can be
damaged. When possible, always park the rig on a
at surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park)
yet. Turn the wheels into the curb if facing downhill
or into traffic if facing uphill.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking
brake and shift into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
Start the engine
Shift into a gear
Release the parking brake
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
The vehicle needs service more often when pulling a
trailer. See this manual’s Maintenance Schedule
or Index for more information. Things that are especially
important in trailer operation are automatic transmission
uid, engine oil, axle lubricant, belts, cooling system
and brake system. It is a good idea to inspect
these before and during the trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
The cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-34.

{CAUTION:
Operating the engine with the air cleaner/lter
off can cause you or others to be burned. The air
cleaner not only cleans the air; it helps to stop
ames if the engine backres. If it is not there and
the engine backres, you could be burned. Do not
drive with it off, and be careful working on the
engine with the air cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre can
cause a damaging engine re. And, dirt can easily get
into the engine, which will damage it. Always have
the air cleaner/lter in place when you are driving.
Automatic Transmission Fluid
How to Check Automatic Transmission
Fluid
It is not necessary to check the transmission uid level.
A transmission uid leak is the only reason for uid loss.
If a leak occurs, take the vehicle to the dealer/retailer
service department and have it repaired as soon as
possible.
There is a special procedure for checking and changing
the transmission uid. Because this procedure is
difficult, you should have this done at the dealer/retailer
service department. Contact your dealer/retailer for
additional information or the procedure can be found
in the service manual. To purchase a service manual,
seeService Publications Ordering Information on
page 7-15.
Notice:Use of the incorrect automatic transmission
uid may damage the vehicle, and the damages
may not be covered by the vehicle’s warranty.
Always use the automatic transmission uid listed in
Recommended Fluids and Lubricants on page 6-13.
Change the uid and lter at the intervals listed in
Additional Required Services on page 6-6, and be sure
to use the uid listed inRecommended Fluids and
Lubricants on page 6-13.

Notice:Ignoring these steps could result in costly
damage to your vehicle that would not be covered
by your warranty.
Trying to start your vehicle by pushing or pulling it
will not work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice:If the other vehicle’s system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles are not touching
each other. If they are, it could cause a ground
connection you do not want. You would not be able
to start your vehicle and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake rmly on both vehicles involved
in the jump start procedure. Put an automatic
transmission in P (Park) or a manual transmission
in NEUTRAL before setting the parking brake.Notice:If you leave the radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered by
the warranty. Always turn off the radio and other
accessories when jump starting the vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlets. Turn off
the radio and all lamps that are not needed.
This will avoid sparks and help save both batteries.
And it could save the radio!
4. Open the hoods and locate the positive (+)
and negative (−) terminal locations or the remote
positive (+) and remote negative (−) terminals of the
other vehicle. Then locate the remote positive (+)
location on your vehicle. SeeEngine Compartment
Overview on page 5-12for more information on
locations the terminals.
