2. When the engine begins cranking, let go of thebutton and the engine cranks automatically until
it starts. If the battery in the keyless access
transmitter is weak, the DIC displays KEY FOB
BATTERY LOW. You can still drive the vehicle.
See “Battery Replacement” underKeyless Access
System Operation
on page 3‑5for more
information. If the fob battery is dead, you need to
insert the fob into the fob slot to enable engine
starting. See “No Fobs Detected” underDIC
Warnings and Messages on page 4‑76.
3. Do not race the engine immediately after starting it. Operate the engine and transmission gently until
the oil warms up and lubricates all moving parts.
4. If the engine does not start and no DIC message is displayed, wait 15 seconds before trying again to
let the cranking motor cool down.
If the engine does not start after 5-10 seconds,
especially in very cold weather (below
0°F or −18°C), it could be flooded with too
much gasoline. Try pushing the accelerator
pedal all the way to the floor while cranking
for up to 15 seconds maximum. Notice:
Cranking the engine for long periods of
time, by pressing the START button immediately
after cranking has ended, can overheat and damage
the cranking motor, and drain the battery. Wait at
least 15 seconds between each try, to allow the
cranking motor to cool down.
When the engine starts, let go of the accelerator. If the
vehicle starts briefly but then stops again, do the same
thing. This clears the extra gasoline from the engine.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine and
protects components. Once cranking has been initiated,
the engine continues cranking for a few seconds or until
the vehicle starts. If the engine does not start, cranking
automatically stops after 15 seconds to prevent
cranking motor damage. To prevent gear damage, this
system also prevents cranking if the engine is already
running.
Notice: The engine is designed to work with the
electronics in the vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you do not,
the engine might not perform properly. Any
resulting damage would not be covered by the
vehicle warranty.

Stopping the Engine
Move the shift lever to P (Park) and press the Acc.
button located on the instrument panel. If the shifter is
not in P (Park), the engine shuts off and the vehicle
goes into the Accessory Mode. The DIC displays SHIFT
TO PARK. Once the shifter is moved to P (Park), the
vehicle turns off.
The DIC displays NO FOB, OFF OR RUN?, if the
keyless access transmitter is not detected inside the
vehicle when it is turned off.
SeeDIC Warnings and Messages
on page 4‑76for
more information.
Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm‐up in
cold weather conditions at or below −18°C (0°F).
Vehicles with an engine coolant heater should be
plugged in at least four hours before starting. Some
models have an internal thermostat in the cord which
will prevent engine coolant heater operation at
temperatures above −18°C (0°F).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located in the front of the engine
compartment, on the passenger side of the vehicle.
3. You must remove the plastic cap to access the plug.
4. Plug it into a normal, grounded 110-volt AC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
You could be seriously injured. Plug the cord into
a properly grounded three-prong 110-volt AC
outlet. If the cord will not reach, use a heavy-duty
three-prong extension cord rated for at least
15 amps.
5. Before starting the engine, be sure to unplug and store the cord as it was before to keep it away from
moving engine parts. If you do not, it could be
damaged.

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 (31,1)Cadillac STS Owner Manual - 2011
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
R (Reverse): Use this gear to back up.
At low vehicle speeds, you can also use R (Reverse)
to rock your vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission. See If
Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on
page 5‑22for additional information.
N (Neutral): In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is already moving, use N (Neutral) only. You can
also use N (Neutral) when the vehicle is being towed.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed. Notice:
Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage the
transmission. The repairs would not be covered by
the vehicle warranty. Be sure the engine is not
running at high speed when shifting the vehicle.
D (Drive): This position is for normal driving. It provides
the best fuel economy. If you need more power for
passing, and you are:
.Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
.Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transmission will shift down to a lower gear
and have more power.
Downshifting the transmission in slippery road
conditions could result in skidding, see “Skidding”under
Loss of Control on page 5‑14.

Driver Shift Control (DSC)
Notice:If you drive the vehicle at a high rpm
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. See
Driver Information Center
(DIC)
on page 4‑69for
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 firmer
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.

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).
