2009 CADILLAC DTS instrument cluster

Content Theft-Deterrent
The security light is
located on the instrument
panel cluster.
To arm the system:
1. Open the door.
2. Lock the door using the power door lock switch with
the door open or the Remote Keyless Entry (RKE)
transmitter. The security light will ash.
3. Close all the doors. The security light will come on
and stay on for approximately 30 seconds.
If a door or the trunk is opened without a key or a
RKE transmitter the horn will sound and the lamps will
ash for about 30 seconds.The theft-deterrent system will not arm if you lock the
doors with a key or use the manual door lock. It arms
only if you use a power door lock with the door open or
the RKE transmitter.
To avoid arming the alarm by accident:
Lock the vehicle with the door key or the manual
door lock.
Always unlock a door with a key or use the RKE
transmitter system. Pressing the unlock button
on the RKE transmitter, or unlocking a door with the
key disarms the content 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
system, or by starting the car with a valid key.
Changes or modications made to this system by
other than an authorized service facility could void
authorization to use the theft system.

Performance Shifting
If the vehicle has this feature, it can detect a change in
driving patterns. If you make an aggressive driving
maneuver, the vehicle’s transmission automatically
shifts to the lowest possible gear to maximize vehicle
performance. The vehicle will automatically return
to normal operation when you return to normal driving
patterns.
Parking Brake
The parking brake pedal is
located to the left of the
regular brake pedal,
near the driver door.
To set the parking brake, hold the regular 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.
A warning chime will sound if the parking brake is set, the
ignition is on, and the vehicle speed is greater than 5 mph
(8 km/h). The brake light will come on and stay on until
the parking brake is released. SeeBrake System
Warning Light on page 3-56for more information.
To release the parking brake, hold the regular brake
pedal down, then push the parking brake pedal down.
When you lift your foot off the parking brake pedal,
the pedal will follow your foot to the released position.
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.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-28.

How the System Works
LDW uses a camera located between the inside rearview
mirror and the windshield to detect the lane markings.
@(Lane Departure Warning):To turn LDW on and off,
press the LDW control, located by the exterior headlamp
control. An indicator on the control will light to indicate
that LDW is on.
When the vehicle is started, the LDW symbol, located in
the instrument panel cluster, will briey come on to
indicate that the light is operational.LDW only operates at speeds of 35 mph (56 km) or
greater. If LDW is turned on when traveling at these
speeds, the LDW symbol will appear green if the system
detects a left or right lane marking. This symbol will
change to amber and ash and three beeps will sound if
you cross a detected lane marking without using the
turn signal.
If the LDW symbol does not appear, LDW is not currently
operating and will not warn you.
To change the volume of the warning chime, see Chime
Volume underDIC Vehicle Customization on page 3-86
for more information.
When the System Does Not Seem To
Work Properly
The LDW symbol will not appear when the system is
having difficulty seeing the lines on the road or if
the view of the camera on the windshield is blocked
with mud, dirt, snow, ice, or slush, if the windshield
is damaged, or when weather limits visibility, such as
while driving in fog, rain, or snow conditions. This is
normal operation, the vehicle does not need service.

on page 5-90.

Information for these features is on the pages following.
Turn and Lane-Change Signals
An arrow on the instrument
panel cluster and in the
outside rearview mirror
ashes in the direction of
the turn or lane change.
Move the lever all the way up or down to signal a
turn. The lever returns automatically when the turn is

the turn signal will ash 3 times.
Raise or lower the lever until the arrow starts to ash to
signal a lane change. Hold it there until the lane change is
complete.
The lever returns to its starting position when it is
released.
If after signaling a turn or lane change the arrow
ashes rapidly or does not come on, a signal bulb
may be burned out.
Have the bulbs replaced. If the bulb is not burned out,
check the fuse. SeeRear Underseat Fuse Block on
page 5-98.

Cruise Control
With cruise control, a speed of approximately 25 mph
(40 km/h) or more can be maintained without keeping
your foot on the accelerator. Cruise control does not work
at speeds below about 25 mph (40 km/h). A cruise control
light appears in the instrument panel cluster when the
cruise control is on.
When the brakes are applied, the cruise control
shuts off.{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use the cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous on slippery roads.
On such roads, fast changes in tire traction can
cause excessive wheel slip, and you could lose
control. Do not use cruise control on slippery roads.
If your vehicle is in cruise control when the Traction
Control System (TCS) begins to limit wheel spin, the
cruise control automatically turns off. SeeTraction
Control System (TCS) on page 4-6. When road
conditions let you safely use it again, the cruise
control can be turned back on.
