cruise control CADILLAC DTS 2008 1.G User Guide

Resuming a Set Speed
Suppose you set the cruise control at a desired speed
and then you apply the brake. This shuts off the
cruise control. But you do not need to reset it.
Once the vehicle is traveling approximately 25 mph
(40 km/h) or more, you can press the +RES
(resume/accelerate) button to return to your desired
preset speed. The cruise light displays again.
The vehicle returns to and stays at your preset speed.
If you press and hold the +RES button, the vehicle
speed increases until you release the button or apply
the brake. Do not hold in the +RES button, if you do not
want the vehicle speed to increase.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher
speed. Press the SET– button, then release
the button and the accelerator pedal. The vehicle
now cruises at the higher speed.
Press the +RES button. Hold it there until you get
up to the desired speed, and then release the
button. To increase your speed in very small
amounts, briey press the +RES button and then
release it. Each time you do this, the vehicle
accelerates approximately 1 mph (1.6 km/h).
The accelerate feature only works after you have set
the cruise control speed by pressing the SET– button.
Reducing Speed While Using Cruise
Control
There are two ways to reduce your speed while using
cruise control:
Press the SET– button until you reach the lower
desired speed, then release it.
To slow down in very small amounts, push the
SET– button briey. Each time you do this, the
vehicle slows down approximately 1 mph (1.6 km/h).
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, the vehicle slows
down to your previous cruise control speed.
3-18

Using Cruise Control on Hills
How well your cruise control works on hills depends
upon the vehicle speed, load, and the steepness of the
hills. When going up steep hills, you might have to
step on the accelerator pedal to maintain the vehicle’s
speed. When going downhill, you might have to brake or
shift to a lower gear to keep the vehicle’s speed
down. Applying the brake or shifting into a lower gear
ends cruise control. If you need to apply the brake
or shift to a lower gear due to the grade of the downhill
slope, you might not want to attempt to use the
cruise control feature.
Ending Cruise Control
To turn off the cruise control, step lightly on the brake
pedal, or press the cancel button on the steering wheel.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.

Adaptive Cruise Control 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. Adaptive Cruise
Control uses radar to detect a vehicle directly ahead in
your path, within a distance of 330 ft (100 m), and
operates at speeds above 25 mph (40 km/h). 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.
3-19

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, the 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.
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)
3-20

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.The Adaptive Cruise
controls are located on
the steering wheel.
The cruise control buttons are located on outboard side
of the steering wheel.
](On):This position turns on the system.
+ Res (Resume/Accelerate):Press this button to
make the vehicle resume to a previously set speed or to
increase the set speed when Adaptive Cruise Control
is already active.
3-21

Set–:Press this button to set the speed or to
decrease the set speed when Adaptive Cruise
Control is already active.
[(Cancel):Press this button to cancel adaptive
cruise control.
+GAP (Increase Following Distance):Press this
button to increase the distance between your vehicle
and other vehicles.
−GAP (Decrease Following Distance):Press this
button to decrease the distance between your vehicle
and other vehicles.
Adaptive cruise control will not work if the master
cylinder brake uid level is low.
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.
3-22

To set Adaptive Cruise Control, do the following:
1. Press the
](On) button.
2. Get up to the speed desired.
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 3-75.
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 4-5and
StabiliTrak
®System on page 4-7. When road conditions
allow you to safely use it again, you may turn the
Adaptive Cruise Control back on.
Increasing Set Speed While Using Adaptive
Cruise Control
There are two ways to increase the set speed:
Use the accelerator to get to the higher speed.
Press the SET– button and then release the
button and the accelerator pedal. The vehicle will
now cruise at the higher speed.
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 your set speed in very small amounts,
move the switch briey to +RES. Each time this
is done, your set speed increases by 1 mph (1 km/h).
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.
3-23

Decreasing Set Speed While Using
Adaptive Cruise Control
Press the SET– button until you reach the lower speed
desired, then release it.
To slow down in very small amounts, briey press the
SET– button. Each time this is done, your set speed
decreases by 1 mph (1 km/h) slower.
Resuming a Set Speed
Suppose the Adaptive Cruise Control is set at a desired
speed and then the brakes are applied. This will turn
off the Adaptive Cruise Control. But it does not need to
be reset.
Once you are going about 25 mph (40 km/h) or more,
press the +RES button. Adaptive Cruise Control
will be engaged with the previously chosen set speed.
Selecting the Follow Distance (GAP)
When the system detects a slower moving vehicle, it will
adjust your vehicle’s speed and maintain 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 rst button
press shows the current follow distance setting on
the DIC. The current follow distance setting will
be maintained until you change it.
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
Adaptive Cruise Control allows, disengage the
system and drive manually.
3-24

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 3-75for more information.
A malfunction is detected in the system.
SeeDIC Warnings and Messages on page 3-75
for more information.
SeeDefensive Driving on page 4-2.
{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 4-2.
3-25

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 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 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.
3-26

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.
