2011 CADILLAC DTS Owners Manual

Black plate (15,1)Cadillac DTS Owner Manual - 2011
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Adaptive Cruise Control (ACC) is an enhancement to
traditional cruise control. It allows you to keep cruise
control engaged in moderate traffic conditions without
having to constantly reset your cruise control. ACC
uses radar to detect a vehicle directly ahead in your
path, within a distance of 100 m (330 ft), and operates
at speeds above 40 km/h (25 mph). 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 2.45 m/sec2 (0.25 g's) of deceleration, which is
comparable to moderate application of the vehicle's
brakes. To disengage ACC, apply the brake. If no
vehicle is in your path, the vehicle will react like
traditional cruise control.
{WARNING:
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 5‑2.

{WARNING:
.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.
(Continued)
WARNING: (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.

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 ACC is
active.
A message on the DIC will also display when ACC is
set. SeeDIC Warnings and Messages on page 4‑65.
Keep in mind speed limits, surrounding traffic speeds,
and weather conditions when adjusting your set speed.
If the vehicle is in ACC when the traction control system
begins to limit wheel spin, the ACC will automatically
disengage. See Traction Control System (TCS)
on
page 5‑6and StabiliTrak®Systemon page 5‑6.
When road conditions allow you to safely use it again,
the ACC can be turned back on.
Increasing Set Speed While Using ACC
If the ACC is already activated,
.Press the +RES button. Hold it there until the
desired set speed is displayed on the Driver
Information Center (DIC), then release the switch.
.To increase the set speed in small amounts, move
the switch briefly to +RES. Each time this is done,
the set speed increases by 1 km/h (1 mph).
Your vehicle will not reach the set speed until the
system determines there is not a vehicle in front of you.
At that point, your vehicle speed will increase to the set
speed.
Decreasing Set Speed While Using ACC
If the ACC is already activated,
.Press the SET– button until the lower speed
desired is reached, then release it.
.To slow down in small amounts, briefly press the
SET– button. Each time this is done, the set speed
decreases by 1 km/h (1 mph) slower.
Resuming a Set Speed
If the ACC is set at a desired speed and then the
brakes are applied, the ACC is disengaged without
erasing the set speed from memory.
Once the vehicle speed is 40 km/h (25 mph) or greater,
press the +RES button. The vehicle returns to the
previously set speed and stays there.
Selecting the Follow Distance (GAP)
When the system detects a slower moving vehicle, it
adjusts your vehicle speed and maintains the follow
distance (gap) you select.
Use the plus and minus buttons on the steering wheel
to adjust the follow distance.
Press the plus button to increase the distance or the
minus button to decrease the distance. The first button
press shows the current follow distance setting on
the DIC. The current follow distance setting will be
maintained until it is changed.

There are six follow distances to choose from. The
follow distance selection ranges from near to far
(one second to two seconds follow time). The distance
maintained for a selected follow distance will vary
based on vehicle speed. The faster the vehicle speed
the further back your vehicle will follow. Consider traffic
and weather conditions when selecting the follow
distance. The range of selectable distances may not be
appropriate for all drivers and driving conditions. If you
prefer to travel at a follow distance farther than ACC
allows, disengage the system and drive manually.
Alerting the Driver
The ACC alert symbol is
located on the display at
the top of the instrument
panel to the right of the
driver.
The alert symbol flashes and a warning beep sounds
when driver action may be required. If ACC is engaged,
the alert symbol will flash when:
.ACC cannot apply sufficient braking because you
are approaching a vehicle too rapidly.
.The vehicle speed drops below about 32 km/h
(20 mph).
.A temporary condition prohibits ACC from
operating. See DIC Warnings and Messageson
page 4‑65for more information.
.A malfunction is detected in the system. See DIC
Warnings and Messageson page 4‑65for more
information.
See Defensive Driving on page 5‑2.
{WARNING:
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. See Defensive Driving on page 5‑2.

Approaching and Following a Vehicle
The vehicle ahead symbol
is located on the top of
the instrument panel to
the right of the driver.
The vehicle ahead symbol only appears when a vehicle
is detected in your path.
If this symbol does not appear, or disappears briefly,
ACC will not respond to vehicles you may see ahead.
{WARNING:
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. ACC automatically slows your vehicle down when
approaching a slower moving vehicle. It then adjusts
your vehicle speed to follow the vehicle in front at the
selected follow distance. Your vehicle speed increases
or decreases 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. Braking may feel or sound different than if
you were applying the brakes yourself. This is normal.
Stationary or Very Slow-Moving Objects
{WARNING:
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.
4-20

Black plate (21,1)Cadillac DTS Owner Manual - 2011
{WARNING:
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 vehicle speed falls below 32 km/h (20 mph) while
following a vehicle ahead, ACC will begin to disengage.
The Driver Alert symbol will flash and the warning beep
will sound. The driver must take action since ACC will
not slow the vehicle to a stop.
Passing a Vehicle/ACC Override
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 4‑65. Once you remove your foot from the
accelerator pedal, ACC will return to normal operation
and be able to apply the brakes, if needed.
{WARNING:
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
{WARNING:
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.
ACC may operate differently in a sharp curve. It may
reduce your vehicle speed if the curve is too sharp.
When following a vehicle and entering a curve, ACC
could lose track of the vehicle in your lane and
accelerate your vehicle. When this happens the Vehicle
Ahead symbol will not appear.
