The theft-deterrent system will not arm if you lock the
doors with a key or use the manual door lock. It
activates only if you use the RKE transmitter or the
power lock on the door.
To avoid activating the alarm by accident do the
following:
Lock the door with the key or the manual door lock
after the doors are closed if you do not want to arm
the theft-deterrent system.
Always unlock a door with a key or use the RKE
transmitter. Pressing the unlock button on the
RKE transmitter disables the theft-deterrent system.
Unlocking a door any other way will activate the
alarm when a door or the trunk is opened.
If you activate the alarm by accident, unlock the driver’s
door with your key. You can also turn off the alarm
by using the unlock button on the RKE transmitter, or by
starting the vehicle with a valid key.
Testing the Alarm
1. Roll down the window, then get out of the vehicle,
keeping the door open.
2. From outside of the vehicle, with the door open,
lock the vehicle using the power door lock switch
or the RKE transmitter and close the door. Wait
approximately 30 seconds until the security
light goes off.
3. Reach in and unlock the door using the manual
lock and open the door. The horn will sound and
the exterior lamps will ash.
The alarm can be turned off by unlocking the driver’s
door with the key, using the unlock button on the
RKE transmitter or by starting the car with a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown.
To replace the fuse, seeFuses and Circuit Breakers on
page 5-104. If the fuse does not need to be replaced,
you may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.

When trying to start the vehicle, if the engine does not
start and the security light comes on, the key may
have a damaged transponder. Turn the ignition off and
try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse. SeeFuses
and Circuit Breakers on page 5-104. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the rst key may be
faulty. See your dealer who can service the
theft-deterrent system and have a new key made.
It is possible for the theft-deterrent system decoder to
learn the transponder value of a new or replacement
key. Up to 10 additional keys may be programmed for
the vehicle. The following procedure is for programming
additional keys only.
Canadian Owners:If you lose or damage your keys,
only a GM dealer can service the theft-deterrent system
to have new keys made. To program additional keys
you will require two current driver’s keys. You must add
a step to the following procedure. After Step 2, repeat
Steps 1 and 2 with the second current driver’s key. Then
continue with Step 3.To program a new key do the following:
1. Verify that the new key has PK3+ stamped on it.
2. Insert the current driver’s key in the ignition
and start the engine. If the engine will not start see
your dealer for service.
3. After the engine has started, turn the key to OFF,
and remove the key.
4. Insert the key to be programmed and turn it to ON
within ten seconds of removing the previous key.
5. The security light will turn off once the key has been
programmed. It may not be apparent that the
security light went on due to how quickly the key is
programmed.
6. Repeat the Steps 1 through 4 if additional keys are
to be programmed.
If the security light comes on and stays on while driving,
you will be able to restart the engine if you turn it off. The
theft-deterrent system, however, is not working properly
and must be serviced by your dealer. Your vehicle is not
protected by the theft-deterrent system at this time.
In an emergency, contact Cadillac Roadside Service

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.
2-29
Shift Speeds (Manual Transmission)
{CAUTION:
If you skip a gear when you downshift, you
could lose control of your vehicle. You could
injure yourself or others. Do not shift down
more than one gear at a time when you
downshift.
Notice:If you skip more than one gear when you
downshift, or if you race the engine when you
release the clutch pedal while downshifting, you
could damage the engine, clutch, driveshaft or the
transmission. Do not skip gears or race the
engine when downshifting.
If the vehicle speed drops below 20 mph (32 km/h), or if
the engine is not running smoothly, you should
downshift to the next lower gear. You may have to
downshift two or more gears to keep the engine running
smoothly or for good performance.
Skip Shift (CTS-V)
1r4:This may appear in the message center in the
speedometer during light throttle, low speed maneuvers
(15 to 19 mph (24 to 31 km/h)). When this message
appears, you can only shift from FIRST (1) to
FOURTH (4) instead of FIRST (1) to SECOND (2).
SeeOne-to-Four Shift Message on page 3-52for more
information.
During the shift from FIRST (1) to FOURTH (4), pull the
shift lever straight back using light force on the shift
lever. You must complete the shift into FOURTH (4) to
turn off this feature. This helps you get the best
possible fuel economy. The skip shift feature is turned
backed on when the vehicle is at a complete stop.
Notice:Forcing the shift lever into any gear except
FOURTH (4), when the One – to – Four Shift
message comes on, may damage the transmission.
Shift only from FIRST (1) to FOURTH (4) when
the One – to – Four Shift message comes on.
This light comes on when:
The engine coolant temperature is higher than
169°F (76°C) and you are going 15 to 19 mph
(24 to 31 km/h).
You are 21 percent throttle or less.

Parking Brake
The parking brake pedal is
located on the lower
portion of the instrument
panel to the left of the
steering wheel.
To set the parking brake, hold the regular brake pedal
down with your right foot and push the parking brake
pedal down with your left foot.
If the ignition is on, the brake system warning light on
the instrument panel cluster should come on. If it
does not, you need to have your vehicle serviced. See
Brake System Warning Light on page 3-38for more
information.To release the parking brake, pull the release lever
located to the left of the steering wheel on the
instrument panel.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
A warning chime will sound if the parking brake is set,
the ignition is on, and the vehicle begins to move.
To stop the chime, fully release the parking brake.

an airbag symbol in Canada, when the passenger
airbag is enabled. SeePassenger Sensing System on
page 1-63for more information.
Cleaning the Mirror
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.
Automatic Dimming Rearview Mirror
with OnStar
®and Compass
The vehicle may have an automatic dimming inside
rearview mirror with a compass and OnStar®controls.
For more information about OnStar®, seeOnStar®
System on page 2-43.
The mirror has an eight-point compass display in the
upper right corner of the mirror. When on, the compass
automatically calibrates, or sets the driving direction,
as the vehicle is driven. If the vehicle has the navigation
option, the direction the vehicle is facing will be
displayed on the navigation screen.
O(On/Off):The on/off button is located on the lower
left side of the mirror and is used for the automatic
dimming and compass functions of the rearview mirror.
2-39
Mirror Operation
The automatic dimming feature comes on each time the
vehicle is started.
To turn the automatic dimming feature on or off, press
the on/off button. The indicator light will illuminate
when this feature is on.
Compass Operation
Press the on/off button once to turn the compass on
or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for
approximately two seconds. After two seconds, the
mirror will display the current compass direction.
Compass Calibration
If after two seconds the display does not show a
compass direction, (N for North for example), there may
be a strong magnetic eld interfering with the compass.
Such interference may be caused by a magnetic
antenna mount, note pad holder, or similar object. If the
letter C appears in the compass window, the compass
may need to be reset or calibrated.The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display reads
a direction.
The compass can be calibrated by pressing and holding
the on/off button until a C is shown in the compass
display.
Compass Variance
Compass variance is the difference between earth’s
magnetic north and true geographic north. If the mirror
is not adjusted for compass variance, the compass
could give false readings.
The mirror is set in zone eight upon leaving the factory.
It will be necessary to adjust the compass to
compensate for compass variance if the vehicle is
driven outside zone eight. Under certain circumstances,
such as a long distance, cross-country trip, it will be
necessary to adjust the compass variance.
