We recommend that you not use seat covers or other
aftermarket equipment other than any that GM has
approved for your specific vehicle. SeeAdding
Equipment to Your Airbag-Equipped Vehicle
on
page 2‑71for more information about modifications
that can affect how the system operates.
{WARNING:
Stowing of articles under the passenger seat
or between the passenger seat cushion and
seatback may interfere with the proper operation
of the passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.
There are parts of the airbag system in several places
around the vehicle. Your dealer and the service manual
have information about servicing the vehicle and the
airbag system. To purchase a service manual, see
Service Publications Ordering Information
on
page 8‑17.
{WARNING:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
inflate during improper service. You can be injured
if you are close to an airbag when it inflates. Avoid
yellow connectors. They are probably part of the
airbag system. Be sure to follow proper service
procedures, and make sure the person performing
work for you is qualified to do so.

If the vehicle does not start and the keyless access
transmitter appears to be undamaged, try another
keyless access transmitter. Or, place the transmitter in
the transmitter pocket. See“NO FOBS DETECTED”
under DIC Warnings and Messages
on page 4‑76for
additional information. Check the fuse. See Fuses and
Circuit Breakers
on page 6‑115. If the engine still does
not start with the other transmitter, the vehicle needs
service. If the engine does start, the first transmitter
may be faulty. See your dealer or have a new keyless
access transmitter programmed to the vehicle.
The immobilizer system can learn new or replacement
keyless access transmitters. Up to four keyless access
transmitters can be programmed for the vehicle.
To program additional transmitters, see “Matching
transmitter(s) to Your Vehicle” underKeyless Access
System Operation on page 3‑5.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice: The vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
.Do not drive at any one constant speed,
fast or slow, for the first 500 miles (805 km).
Do not make full-throttle starts. Avoid
downshifting to brake or slow the vehicle.
.Avoid making hard stops for the first
200 miles (322 km) or so. During this time the
new brake linings are not yet broken in. Hard
stops with new linings can mean premature
wear and earlier replacement. Follow this
breaking-in guideline every time you get new
brake linings.
.Do not tow a trailer during break-in. See
Towing a Trailer
on page 5‑31for the trailer
towing capabilities of your vehicle and more
information.
Following break‐in, engine speed and load can be
gradually increased.

The length of time the heater should remain plugged in
depends on several factors. Ask a dealer in the area
where you will be parking the vehicle for the best advice
on this.
Automatic Transmission Operation
There are several
different positions for the
shift lever.
P (Park): This position locks the rear wheels. It is the
best position to use when you start the engine because
the vehicle cannot move easily.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the 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 the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). See Shifting Into
Park
on page 3‑34. If you are pulling a trailer,
see Towing a Trailer on page 5‑31.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You must fully
apply your regular brakes first and then press the shift
lever button before you can shift from P (Park) when the
vehicle is running. If you cannot shift out of P (Park),
ease pressure on the shift lever and push the shift
lever all the way into P (Park) as you maintain brake
application. Then press the shift lever button and move
the shift lever into another gear. See Shifting Out of
Park on page 3‑35.
3-30
Black plate (33,1)Cadillac STS Owner Manual - 2011
If shifting is prevented for any reason, the selected gear
will flash multiple times, indicating that the transmission
has not shifted gears.
The transmission will allow you to shift to the gear
selected and will automatically downshift when the
vehicle comes to a stop. This will allow for more power
during take-off and passing.
Parking Brake
The parking brake pedal
is located on the lower
portion of the instrument
panel to the left of the
steering wheel.
The vehicle has a push-to-release parking brake pedal.
To set the parking brake, hold the brake pedal down,
then push the parking brake pedal down. 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 the vehicle serviced. See
Brake
System Warning Light
on page 4‑58for more
information.
To release the parking brake, hold the brake pedal
down, then push the parking brake pedal. When you
release the park brake pedal, the parking brake
releases.
Notice: Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
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.
If you are towing a trailer and parking on a hill, see
Towing a Trailer
on page 5‑31for more information.

Shifting Into Park
{WARNING:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake firmly set. The vehicle can roll. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the 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 5‑31
.
To shift into P (Park), use the following steps: 1. Hold the brake pedal down.
2. Move the shift lever into P (Park) 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 foot still holding the brake pedal down, set the parking brake. See Parking Brake
on
page 3‑33for more information.
4. Turn the ignition off.
Leaving the Vehicle With the Engine
Running
{WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly
if the shift lever is not fully in P (Park) with the
parking brake firmly set. And, if you leave the
vehicle with the engine running, it could overheat
and even catch fire. You or others could be
injured. Do not leave the vehicle with the engine
running.
If you leave the vehicle with the engine running, the
vehicle must be in P (Park) and the parking brake set.
After shifting into P (Park), try to move the shift lever out
without first pushing the button on the shift lever. If you
can, the shift lever was not fully locked into P (Park).
3-34
Black plate (35,1)Cadillac STS Owner Manual - 2011
Torque Lock
Torque lock is when the weight of the vehicle puts too
much force on the parking pawl in the transmission.
This happens when parking on a hill and shifting the
transmission into P (Park) is not done properly and then
it is difficult to shift out of P (Park). To prevent torque
lock, set the parking brake and then shift into P (Park).
To find out how, see“Shifting Into P (Park)” listed
previously.
If torque lock does occur, your vehicle may need to be
pushed uphill by another vehicle to relieve the parking
pawl pressure, so you can shift out of P (Park).
Shifting Out of Park
Shift lock release prevents shifting out of P (Park)
unless the vehicle is running or in Accessory mode and
the brake pedal is applied.
The shift lock release is always functional except in the
case of an uncharged or low voltage (less than 9‐volt)
battery. See Jump Starting
on page 6‑38for more
information. To shift out of P (Park) use the following:
1. Apply the brake pedal.
2. Press the shift lever button.
3. Move the shift lever to the desired position.
If you still are unable to shift out of P (Park): 1. Fully release the shift lever button.
2. While holding down the brake pedal, press the shift lever button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift lever from P (Park),
consult your dealer or a professional towing service.
Parking Over Things That Burn
{WARNING:
Things that can burn could touch hot exhaust
parts under the vehicle and ignite. Do not park
over papers, leaves, dry grass, or other things that
can burn.
