2005 CADILLAC STS ESP

Detecting the Vehicle Ahead
The vehicle ahead symbol will only appear on the
HUD when a vehicle ahead of you is detected in your
path. If this symbol does not appear, or disappears
briey, FCA will not respond to vehicles you may see
ahead. The symbol may disappear on curves, highway
exit ramps, or hills. Also, when another vehicle enters
the same lane as you, the FCA system will not
detect the vehicle until it is completely in your
driving lane.
{CAUTION:
When the Adaptive Cruise Control radar is
blocked by snow, ice, or dirt, it may not detect
a vehicle ahead. FCA may not help you avoid a
collision under these conditions. Do not use
FCA when the radar is blocked by snow, ice,
or dirt. Keep your radar clean. See “Cleaning
the System” underAdaptive Cruise Control on
page 3-20.
{CAUTION:
FCA may not detect and warn soon enough to
stationary or slow-moving vehicles or other
objects ahead of you. You could crash into an
object ahead of you. Do not rely on FCA when
approaching stationary or slow-moving
vehicles or other objects.
Unnecessary Warnings
FCA may occasionally provide an unnecessary warning
to guard rails, signs, and other stationary objects.
This is normal operation, your vehicle does not need
service.
Other Messages
There are three messages that may appear on the
Driver Information Center (DIC). They are CLEAN
RADAR, RADAR CRUISE NOT READY and SERVICE
RADAR CRUISE. SeeDIC Warnings and Messages
on page 3-78.

When it is engaged by the driver, the system can
apply limited braking or acceleration of the vehicle,
automatically, to maintain a selected follow distance
to the vehicle ahead. Braking is limited to
0.25 g’s (2.45 m/sec2) of deceleration, which is
comparable to moderate application of the vehicle’s
brakes. To disengage Adaptive Cruise Control, apply
the brake. If no vehicle is in your path, your vehicle
will react like traditional cruise control.
{CAUTION:
Adaptive Cruise Control will not apply hard
braking or bring the vehicle to a complete
stop. It will not respond to stopped vehicles,
pedestrians or animals. When you are
approaching a vehicle or object, Adaptive
Cruise Control may not have time to slow your
vehicle enough to avoid a collision. Your
complete attention is always required while
driving and you should be ready to take action
and apply the brakes. For more information,
seeDefensive Driving on page 4-2.
{CAUTION:
On winding roads, Adaptive Cruise Control
may not detect a vehicle ahead. You could
crash into a vehicle ahead of you. Do not
use Adaptive Cruise Control on winding
roads.
In stop-and-go traffic, Adaptive Cruise
Control may not have time to slow your
vehicle enough to avoid a collision
because of the rapidly changing traffic
conditions. Do not use Adaptive Cruise
Control in stop-and-go traffic.
On slippery roads, fast changes in tire
traction can cause needless wheel
spinning, and you could lose control. Do
not use cruise control on slippery roads.
When weather limits visibility, such as
when in fog, rain, or snow conditions,
Adaptive Cruise Control performance is
limited. There may not be enough distance
to adapt to the changing traffic conditions.
Do not use cruise control when visibility
is low.
3-21

The Adaptive Cruise
controls are located
on the end of the
multifunction lever.
9(Off):This position turns the system off.
R(On):This position turns the system on.
S(Resume/Increase):Push the switch to this symbol
to make the vehicle resume to a previously set speed
or to increase the set speed when Adaptive Cruise
Control is already active.
T(Set/Decrease):Press this button to set the
speed or to decrease the set speed when Adaptive
Cruise Control is already active.
Engaging Adaptive Cruise Control With
the Set Button
{CAUTION:
If you leave your Adaptive Cruise Control
switch on when you are not using cruise, you
might hit a button and go into cruise when you
do not want to. You could be startled and even
lose control. Keep the Adaptive Cruise Control
switch off until you want to use cruise control.
{CAUTION:
If you operate Adaptive Cruise Control without
your Head-up Display (HUD) properly adjusted,
your Adaptive Cruise Control settings may
not be visible. You could forget your settings
and be startled by Adaptive Cruise Control
response and even lose control. Keep your
HUD on and properly adjusted when using
Adaptive Cruise Control.
3-22

If this symbol does not appear, or disappears briey,
Adaptive Cruise Control will not respond to vehicles
you may see ahead.
{CAUTION:
When the Adaptive Cruise Control radar is
blocked by snow, ice, or dirt, it may not detect
a vehicle ahead. Adaptive Cruise Control may
not have time to slow your vehicle enough to
avoid a collision. Do not use Adaptive Cruise
Control when the radar is blocked by snow,
ice, or dirt. Keep your radar clean. See
“Cleaning the System” later in this section.Adaptive Cruise Control will, automatically, slow your
vehicle down when approaching a slower moving
vehicle. It will then adjust your speed to follow the
vehicle in front at the selected follow distance. Your
speed will increase or decrease to follow the vehicle in
front of you but will not exceed the set speed. It
may apply limited braking, if necessary. When braking is
active, your brake lights will come on. It may feel or
sound different than if you were applying the brakes
yourself. This is normal.
3-27

Curves in the Road
{CAUTION:
Due to Adaptive Cruise Control limitations in
curves, it may respond to a vehicle in another
lane, or may not have time to react to a vehicle
in your lane. You could crash into a vehicle
ahead of you, or lose control of your vehicle.
Give extra attention in curves and be ready to
use the brakes if necessary. Select an
appropriate speed while driving in curves.
Adaptive Cruise Control may operate differently in a
sharp curve. It may reduce your speed if the curve is
too sharp.When following a vehicle and entering a curve, Adaptive
Cruise Control could lose track of the vehicle in your
lane and accelerate your vehicle. When this happens,
the vehicle ahead symbol will not appear on the HUD.
3-30

Adaptive Cruise Control may detect a vehicle that is not
in your lane and apply the brakes.
Adaptive Cruise Control may, occasionally, provide
a driver alert and/or braking that you consider
unnecessary. It could respond to signs, guardrails and
other stationary objects when entering or exiting a curve.
This is normal operation. Your vehicle does not need
service.
Highway Exit Ramps
{CAUTION:
Adaptive Cruise Control may lose track of the
vehicle ahead and accelerate up to your set
speed while entering or on highway exit
ramps. You could be startled by this
acceleration and even lose control of the
vehicle. Disengage Adaptive Cruise Control
before entering a highway exit ramp. Do not
use Adaptive Cruise Control on exit ramps.
3-31

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.
When the automatic lights are enabled and it is dark
enough outside, the DRL will turn off and the low-beam
headlamps will turn on. When it is bright enough
outside, the low-beam headlamps will go off, and the
DRL will turn back on. If you start your vehicle in a
dark garage, the automatic headlamp system will
come on immediately. Once you leave the garage, it
will take about one minute for the automatic headlamp
system to change to DRL if it is light outside.During that delay, your instrument panel cluster may
not be as bright as usual. Make sure your instrument
panel brightness lever is in the full bright position.
SeeInstrument Panel Brightness on page 3-41.
To operate your vehicle with the DRL off, turn the
exterior lamp control off and then do one of the
following:
Turn the exterior lamp control to the parking lamp
position.
Turn the exterior lamp control to the headlamp
position.
Turn the exterior lamp control from AUTO to off and
back to AUTO.
An AUTOMATIC LIGHTS OFF message will appear on
the DIC, showing that automatic lighting has been
disabled.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

When a CD is playing, press the minus sign to go to the
start of the current track, if more than 10 seconds
have played. Press the plus sign to go to the next track.
If either the minus or the plus button are pressed
more than once, the player will continue moving
backward or forward through the CD.
Press and hold the SEEK plus or minus button, until
you hear a beep. The CD will fast forward or fast reverse
through the CD. Press either button again to play the
passage.
If you have the navigation system, some of the audio
steering wheel controls work when a DVD is playing in
the navigation radio. See the Navigation System
manual for more information.
Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range can cause
station frequencies to interfere with each other. Static
can occur on AM stations caused by things like
storms and power lines. Try reducing the treble to
reduce this noise.
FM Stereo
FM stereo will give the best sound, but FM signals will
reach only about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to fade in and out.
XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast to coast. Just as with FM, tall
buildings or hills can interfere with satellite radio signals,
causing the sound to fade in and out. The radio may
display NO XM SIGNAL to indicate interference.
Cellular Phone Usage
Cellular phone usage may cause interference with your
vehicle’s radio. This interference may occur when
making or receiving phone calls, charging the phone’s
battery, or simply having the phone on. This interference
is an increased level of static while listening to the
radio. If static is received while listening to the radio,
unplug the cellular phone and turn it off.
