2007 CADILLAC DTS warning

Detecting the Vehicle Ahead
The vehicle ahead symbol, located next to the
FCA symbol, will only appear 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 179.
{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 Alerts
FCA may occasionally provide alerts that you
consider unnecessary. It could respond to a turning
vehicle ahead of you, 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 246.

Windshield Washer
{CAUTION:
In freezing weather, do not use your
washer until the windshield is warmed.
Otherwise the washer uid can form ice
on the windshield, blocking your vision.
J(Washer Fluid):Press and release
this paddle, located at the top of the turn
signal/multifunction lever, to spray washer
uid on the windshield. The wipers will clear
the windshield and either stop or return to your
preset speed. For more washer cycles, press
and hold the paddle.
_(Heated Washer Fluid):The heated
windshield washer uid system, if your vehicle
has this feature, may be used to help clear
ice, snow, tree sap, or bugs from your windshield.Sliding the switch on the turn signal/multifunction
lever to this position and then releasing it will
activate the heated windshield washer uid
system. This activation will initiate four heated
wash/wipe cycles. The rst heated wash/wipe
cycle may take up to 40 seconds to occur,
depending on outside temperature. After the rst
wash/wipe cycle, it may take up to 20 seconds
for each of the remaining cycles. The heated
windshield washer uid system may be turned off
at any time by sliding the switch on the turn
signal/multifunction lever to this position again.
When the heated windshield washer uid system
is activated under certain outside temperature
conditions, steam may ow out of the washer
nozzles for a short period of time before washer
uid is sprayed. This is a normal condition.
WASHER FLUID LOW ADD FLUID will be
displayed on the Driver Information Center (DIC)
when the washer uid is low. SeeDIC Warnings
and Messages on page 246.

{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.
Adaptive Cruise Control may not have
time to slow your vehicle enough to
avoid a crash when you are driving
in conditions where vehicles may
suddenly slow or stop ahead of you,
enter your lane, or cross your vehicle’s
path. If you are driving in these
conditions, do not use Adaptive Cruise
Control. The warning beep and alert
symbol may indicate that you are
driving in conditions where Adaptive
Cruise Control should not be used. See
“Alerting the Driver” in this section.
CAUTION: (Continued)
CAUTION: (Continued)

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.
181

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.
The set speed is selected by the driver. This is the
speed you will travel if there is no vehicle
detected in your path.
To set Adaptive Cruise Control, do the following:
1. Press the
](On) button.
2. Get up to the speed you want.
3. Press in the SET– button and release it.
4. Take your foot off the accelerator pedal.Once Adaptive Cruise Control is set, it may
immediately apply the brakes if it detects a vehicle
ahead is too close or moving slower than your
vehicle.
The on symbol is located on the display at the top
of the instrument panel to the right of the driver.
When the on symbol is lit on the display, it
indicates that Adaptive Cruise Control is active.
A message on the DIC will also display when
Adaptive Cruise Control is set. SeeDIC Warnings
and Messages on page 246.
Keep in mind speed limits, surrounding traffic
speeds, and weather conditions when adjusting
your set speed.
If your vehicle is in Adaptive Cruise Control when
the traction control system begins to limit wheel
spin, the Adaptive Cruise Control will automatically
disengage. SeeTraction Control System (TCS)
on page 309andStabiliTrak
®System on
page 311. When road conditions allow you to
safely use it again, you may turn the Adaptive
Cruise Control back on.
183

Alerting the Driver
The Adaptive Cruise
Control alert symbol is
located on the display at
the top of the instrument
panel to the right of the
driver.
The alert symbol will ash and a warning beep
will sound when driver action may be required.
If Adaptive Cruise Control is engaged, the
alert symbol will ash when:
Adaptive Cruise Control cannot apply sufficient
braking because you are approaching a
vehicle too rapidly.
The vehicle speed drops below about
20 mph (32 km/h).
A temporary condition prohibits Adaptive
Cruise Control from operating. SeeDIC
Warnings and Messages on page 246for more
information.
A malfunction is detected in the system. See
DIC Warnings and Messages on page 246
for more information.
SeeDefensive Driving on page 302.
{CAUTION:
Adaptive Cruise Control has only limited
braking ability to slow your vehicle. In
some cases, Adaptive Cruise Control may
not have time to slow your vehicle enough
to avoid a collision. Be ready to take
action and apply the brakes yourself.
SeeDefensive Driving on page 302.
186

Stationary or Very Slow-Moving Objects
{CAUTION:
Adaptive Cruise Control may not detect
and react to stationary or slow-moving
vehicles or other objects ahead of you.
You could crash into an object ahead of
you. Do not use Adaptive Cruise Control
when approaching stationary or
slow-moving vehicles or other objects.
{CAUTION:
Adaptive Cruise Control may not detect
and react to stationary or slow-moving
vehicles or other objects ahead of you.
Your vehicle may accelerate toward
objects, such as a stopped vehicle that
suddenly appears after the lead vehicle
changes lanes. Your complete attention is
always required while driving and you
should be ready to take action and apply
the brakes.
Low-Speed Deactivation
If your speed falls below 20 mph (32 km/h) while
following a vehicle ahead, Adaptive Cruise Control
will begin to disengage. The Driver Alert symbol will
ash and the warning beep will sound. The driver
must take action since Adaptive Cruise Control will
not slow the vehicle to a stop.
188

Passing a Vehicle/Adaptive Cruise Control
Override
If you need to increase speed to pass a vehicle,
use the accelerator pedal. While you are doing
this, the system will not automatically apply
the brakes. A message will appear on the DIC.
SeeDIC Warnings and Messages on page 246.
Once you remove your foot from the accelerator
pedal, Adaptive Cruise Control will return to normal
operation and be able to apply the brakes,
if needed.
{CAUTION:
If you rest your foot on the accelerator
pedal, the system will not automatically
apply the brakes. You could crash into a
vehicle ahead of you. Do not rest your
foot on the accelerator pedal when using
Adaptive Cruise Control.
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.
189

Using Adaptive Cruise Control on Hills
and When Towing a Trailer
How well Adaptive Cruise Control will work on hills
and when towing a trailer depends on your vehicle’s
speed, vehicle load, traffic conditions and the
steepness of the hills. It may not detect a vehicle
in your lane while driving on hills. When going up
steep hills, you may want to use the accelerator
pedal to maintain your vehicle’s speed. When going
downhill, especially when towing a trailer, you may
want to brake to keep your speed down. Applying
the brake disengages the system. You may choose
not to use Adaptive Cruise Control on steep hills,
especially when towing a trailer.
Disengaging Adaptive Cruise Control
To turn off the system, apply the brake pedal,
press the cancel button, or press the Adaptive
Cruise Control button.
Erasing Set Speed Memory
When you press the Adaptive Cruise Control
button or turn the ignition off, the set speed
memory is erased.
Other Messages
There are three additional messages that may
appear on the DIC. They are SERVICE RADAR
CRUISE, RADAR CRUISE NOT READY and
CLEAN RADAR. These messages will appear
to indicate a problem with the Adaptive Cruise
Control. SeeDIC Warnings and Messages
on page 246for more information.
Cleaning the System
The radar can become blocked by snow, ice, or
dirt. If so, you may need to turn off the engine and
clean the lens. Remember, do not use Adaptive
Cruise Control in icy conditions, or when visibility
is low, such as in fog, rain or snow.
The emblem/lens is located in the center of
the grille.
To clean the emblem/lens, wipe the surface with a
soft cloth. After cleaning the emblem/lens, try to
engage the Adaptive Cruise Control. If you
are unable to do so, see your dealer.
