2006 CADILLAC CTS automatic transmission

Driver Shift Control (DSC)
Notice:If you drive your vehicle at high RPMs
without upshifting while using Driver Shift Control
(DSC), you could damage your vehicle. Always
upshift when necessary while using DSC.
Your automatic transmission has a Driver Shift Control
(DSC) feature that allows you to change gears similar to a
manual transmission. To use the DSC feature:
1. Slide the shift lever over from AUTOMATIC
OVERDRIVE (D) to the right into the DSC area.
The sport mode light in the
instrument panel cluster
will come on.
If you do not move the shift lever forward or
rearward, the vehicle will be in sport mode. When
you are in the sport mode the vehicle will still
shift automatically. While driving in sport mode, the
transmission may remain in a gear longer than it
would in the normal driving mode based on braking,
throttle input, and vehicle lateral acceleration.
2. To enter the DSC mode, press the shift lever
forward to upshift or rearward to downshift.The odometer on the instrument panel cluster will
change from the mileage to a number indicating the
requested gear range when moving the shift lever
forward or rearward. SeeSpeedometer and Odometer
on page 3-33for more information on the odometer.
While using the DSC feature, the vehicle will have rmer
shifting and increased performance. You can use this
for sport driving or when climbing or 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.
If shifting is prevented for any reason, the currently
selected gear will ash multiple times, indicating that the
transmission has not shifted gears.
While in the DSC mode, the transmission will
automatically downshift when the vehicle comes to a stop
and while quickly applying the accelerator to increase
speed. This will allow for more power during take-off.
When accelerating your vehicle from a stop in snowy
and icy conditions, you may want to shift into second
gear. A higher gear ratio allows you to gain more traction
on slippery surfaces.

Shifting Into Park (P)
(Automatic Transmission)
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle will
not move, even when you are on fairly level
ground, use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 4-39.To shift into PARK (P), use the following steps:
1. Hold the brake pedal down with your right foot.
2. Move the shift lever into PARK (P) by pressing the
button on the front of the shift lever while pushing
the lever all the way toward the front of the vehicle.
Release the button.
3. With your right foot still holding the brake pedal
down, set the parking brake with your left foot.
SeeParking Brake on page 2-33for more
information.
4. Turn the key to OFF.
5. Remove the key from the ignition switch and take it
with you. If you can leave your vehicle with the key
in your hand, the vehicle is in PARK (P).

Leaving Your Vehicle With the Engine
Running (Automatic Transmission)
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is rmly set before you leave it. After you
have moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move
the shift lever away from PARK (P) without rst pushing
the button on the shift lever. If you can, it means that
the shift lever was not fully locked into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl
in the transmission. You may nd it difficult to pull the
shift lever out of PARK (P). This is called “torque
lock.” To prevent torque lock, set the parking brake and
then shift into PARK (P) properly before you leave
the driver’s seat. To nd out how, see “Shifting
Into PARK (P)” listed previously.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to take some of
the pressure from the parking pawl in the transmission,
so you can pull the shift lever out of PARK (P).

Shifting Out of Park (P)
(Automatic Transmission)
Your vehicle has an automatic transmission shift lock
control system. You have to fully apply your regular
brakes before you can shift from PARK (P) when the
ignition is in ON. SeeAutomatic Transmission Operation
on page 2-27for more information.
If you cannot shift out of PARK (P), release the button
on the shift lever and ease the pressure on the shift
lever. Push the shift lever all the way into PARK (P)
while pushing the button on the shift lever as you
maintain brake application. Then move the shift lever
into the desired gear.
Parking Your Vehicle
(Manual Transmission)
Before you get out of your vehicle, place the shift lever in
REVERSE (R) and rmly apply the parking brake. Turn
the ignition key to OFF, press the release button and
remove the key. See “Key Release Button” underIgnition
Positions on page 2-22for more information.
If you are towing a trailer, seeTowing a Trailer on
page 4-39.

Running the Engine While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-37.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
Winter Driving on page 4-27.
{CAUTION:
It can be dangerous to get out of your vehicle
if the automatic transmission shift lever is not
fully in PARK (P) with the parking brake rmly
set. Your vehicle can roll. Do not leave your
vehicle when the engine is running unless you
have to. If you have left the engine running,
the vehicle can move suddenly. You or others
could be injured. To be sure your vehicle will
not move, even when it is on fairly level
ground, always set the parking brake and
move the automatic transmission shift lever to
PARK (P), or the manual transmission shift
lever to NEUTRAL.
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park (P) (Automatic
Transmission) on page 2-34andParking Your Vehicle
(Manual Transmission) on page 2-36.
If you are parking on a hill and if you are pulling a
trailer, seeTowing a Trailer on page 4-39.

Anti-Pinch Feature Override
A condition may exist that causes the anti-pinch feature
of the sunroof to activate due to weather or an
obstruction. In an emergency, the anti-pinch feature can
be overridden in a supervised mode.
To override the anti-pinch feature rotate the sunroof
control to the closed position, then press the control
upward and continue pressing upward until the sunroof
reaches the desired position.
In this mode, the sunroof can still close on an object in
its path. Use care when using the override mode.
Vehicle Personalization

also have features that can be programmed through the
Driver Information Center (DIC). SeeDIC Vehicle
Personalization on page 3-70for more information.
Memory Seat and Mirrors
If your vehicle has the memory feature, you can
program and recall memory settings for the driver’s
seating and outside rearview mirror driving positions for
up to two drivers.The buttons for this feature
are located on the driver’s
door armrest.
