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.

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.

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.

death. Never run the engine in an enclosed area
that has no fresh air ventilation. For more
information, seeEngine Exhaust on page 3‑36.
{WARNING:
It can be dangerous to get out of the vehicle if the
automatic transmission 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 after you move the shift lever to P (Park).
Follow the proper steps to be sure the vehicle will not
move. See Shifting Into Park on page 3‑34.

Compass
Compass Operation
PressOto turn the compass on or off.
When the ignition and the compass feature are on, the
mirror displays the compass heading after a few
seconds.
Compass Calibration
If after few seconds, the display does not show a
compass heading (for example, N for North), there may
be a strong magnetic field interfering with the compass.
Interference can be caused by a magnetic antenna
mount, magnetic note pad holder or a similar magnetic
item. If the letter C should ever appear in the compass
window, the compass may need calibration.
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 placed in calibration mode
manually by pressing and holding
Ountil a C is shown
in the compass display.
Compass Variance
The mirror is set to zone eight. If you do not live in zone
eight or drive out of the area, the compass variance
needs to be changed to the appropriate zone.
To adjust for compass variance:
1. Find the current location and variance zone number on the following zone map.
2. Press and holdOuntil a zone number displays.

Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
For vehicles with the URPA system, it operates at
speeds less than 3 mph (5 km/h), and assists the driver
with parking and avoiding objects while in R (Reverse).
The sensors on the rear bumper are used to detect the
distance to an object up to 5 feet (1.5 m) behind the
vehicle and at least 10 inches (25.4 cm) off the ground.
{WARNING:
The Ultrasonic Rear Parking Assist (URPA)
system does not replace driver vision. It cannot
detect:
.Objects that are below the bumper,
underneath the vehicle, or too close or far
from the vehicle
.Children, pedestrians, bicyclists, or pets.(Continued)
WARNING: (Continued)
If you do not use proper care before and while
backing, vehicle damage, injury, or death could
occur. Even with URPA, always check behind the
vehicle before backing up. While backing, be sure
to look for objects and check the vehicle's mirrors.
The display is located in
the dome lamp and can
be seen by looking over
your right shoulder.
URPA uses three color-coded lights to provide distance
and system information.
3-41
Black plate (42,1)Cadillac STS Owner Manual - 2011
How the System Works
URPA comes on automatically when the shift lever is
moved into R (Reverse). The rear display briefly
illuminates to indicate the system is working.
URPA operates only at speeds less than 3 mph
(5 km/h). If the vehicle is above this speed, the red light
on the rear display will flash.
To be detected, objects must be at least 10 inches
(25.4 cm) off the ground and below trunk level. Objects
must also be within 5 feet (1.5 m) from the rear bumper.
This distance may be less during warmer or humid
weather.
A single beep will sound the first time an object is
detected between 20 inches (0.5 m) and 5 feet (1.5 m)
away. Beeping will occur when the vehicle is closer than
20 inches (0.5 m) from the object.The following describes what will occur with the URPA
display as the vehicle gets closer to a detected object:
Description English Metric
amber light 5 ft 1.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights/ continuous beep 20 in 0.5 m
amber/amber/red lights flashing and
continuous beep 1 ft 0.3 m
