automatic transmission CADILLAC STS 2006 1.G User Guide

Vehicle Personalization
Your vehicle has personalization that allows you to
program certain features to a preferred setting for up to
two drivers. The back of the keyless access transmitters
are labelled 1 or 2. Additional keyless access transmitters
programmed to the vehicle, as 3 and/or 4, do not have
a number on the back and are not capable of being
personalized. The number of programmable features
varies depending upon which vehicle options are
purchased.
On all vehicles, features such as climate control settings,
radio and XM™ preset settings, exterior lighting at unlock
and remote lock unlock conrmation, and language have
already been programmed for your convenience. Your
vehicle also has an automatic door locking feature that
is always on. You cannot turn the automatic door locking
feature off. SeeProgrammable Automatic Door Locks
on page 2-13.
Some vehicles have additional features that can be
programmed including the seat, steering column, and
outside rearview mirror position.
If your vehicle has the base audio system, the following
information explains the vehicle personalization on
your vehicle.If your vehicle has the Navigation system, see
“Personalization” in the Index of the Navigation System
manual for information on vehicle personalization.
If your vehicle has the ability to program additional
personalization features, the driver’s preferences
are recalled by pressing any button on the keyless
access transmitter, 1 or 2, by selecting Driver 1 or 2
on the radio display, or when a valid keyless access
transmitter is detected upon opening the driver’s door.
If more than one valid keyless access transmitter is
detected upon opening the driver’s door, the driver
preferences for the lowest driver number will be recalled.
Certain features can be programmed not to recall until
the ignition is turned off.
To change feature preferences, use the following
procedure.
Entering the Personal Settings Menu
To enter the feature programming mode, use the
following procedure:
1. Be sure the ignition is either on, in ACC position, or
in RAP and place the transmission in PARK (P) or
the vehicle speed is less than 6 mph (9 km/h).
2. Press any button on the appropriate keyless access
transmitter to identify yourself as Driver 1 or
Driver 2.

Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
about six seconds. For this feature to work, automatic
lighting must be enabled. SeeHeadlamps on page 3-31
for additional information.
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They will also turn
off if the windshield wiper control is turned off.
Headlamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver’s door is opened with the ignition off.
SeeLights On Reminder on page 3-71for additional
information.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.
The DRL system will make the turn signal lamps come
on when the following conditions are met:
It is still daylight and the ignition is on,
the automatic lights are enabled, and
the transmission is not in PARK (P).
When DRL are on, only your front turn signal lamps will
be on. No other exterior lamps will be on when the DRL
are being used. Your instrument panel will not be lit.

Driver Information Center (DIC)
The Driver Information Center (DIC) gives you the
status of many of your vehicle’s systems. The DIC is
also used to display warning/status messages. All
messages will appear in the DIC display located at the
bottom of the instrument panel cluster, below the
tachometer and speedometer. The DIC buttons are
located on the instrument panel, to the left of the
steering wheel.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the current driver and the
information that was last displayed before the engine
was turned off.
The top line of the DIC display shows the vehicle system
information and the warning/status messages. The
bottom line of the DIC display shows either the odometer,
the trip odometer A or the trip odometer B information on
the left side. Only one odometer can appear at a time.
See “Trip Information” underDIC Controls and Displays
on page 3-74for information on changing the display to
show the odometer or trip odometer information. The
bottom line of the DIC display also shows the outside
temperature on the right side and the shift lever position
indicator in the center.SeeAutomatic Transmission Operation (5-Speed
Automatic) on page 2-28orAutomatic Transmission
Operation (6-Speed Automatic) on page 2-32for more
information on the shift lever positions.
When the sport mode is active, an S will appear next to
the shift position indicator on the center of the DIC
display. When the manual mode is active, an M will
appear on the DIC display. When the normal mode is
active, only the shift position indicator will appear. While
the Driver Shift Control (DSC) feature is active, the DIC
will change to show the selected gear. See “Driver Shift
Control (DSC)” underAutomatic Transmission Operation
(5-Speed Automatic) on page 2-28orAutomatic
Transmission Operation (6-Speed Automatic) on
page 2-32for more information.
If a problem is detected, a warning message will appear
on the display. Be sure to take any message that
appears on the display seriously and remember that
clearing the message will only make the message
disappear, not correct the problem.

Steering Tips
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject
to the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there is no traction, inertia
will keep the vehicle going in the same direction. If
you have ever tried to steer a vehicle on wet ice, you
will understand this.
The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle
at which the curve is banked, and your speed. While you
are in a curve, speed is the one factor you can control.
Suppose you are steering through a sharp curve.
Then you suddenly accelerate. Both control
systems — steering and acceleration — have to do
their work where the tires meet the road. Adding the
sudden acceleration can demand too much of those
places. You can lose control. SeeTraction Control
System (TCS) on page 4-9andStabiliTrak
®System
on page 4-11.
What should you do if this ever happens? Ease up on
the accelerator pedal, steer the vehicle the way you
want it to go, and slow down.Since your vehicle is equipped with StabiliTrak
®,
the system may be active. SeeDIC Warnings and
Messages on page 3-79andStabiliTrak
®System on
page 4-11.
Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds
are based on good weather and road conditions. Under
less favorable conditions you will want to go slower.
If you need to reduce your speed as you approach
a curve, do it before you enter the curve, while your
front wheels are straight ahead.
Try to adjust your speed so you can “drive” through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
To help you steer in the direction you want to go, during
certain sharp or sudden cornering maneuvers, gear
selection is controlled. This will maximize the available
drive wheel torque and minimize the transmission
response time and shift activity. During this kind of
maneuver, the transmission shifts automatically
as vehicle speed changes.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 5-3.

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
start your engine
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store
the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you are
pulling a trailer. See the Maintenance Schedule for
more on this. Things that are especially important in
trailer operation are automatic transmission uid (do not
overll), engine oil, drive belt, cooling system and
brake system. Each of these is covered in this manual,
and the Index will help you nd them quickly. If you
are trailering, it is a good idea to review this information
before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-30.
