2008 CADILLAC DTS cruise control

Cruise Control
With cruise control, you can maintain a speed of
approximately 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This is helpful on
long trips. Cruise control does not work at speeds
below about 25 mph (40 km/h). When cruise control is
on, you will see a cruise light on the instrument
panel cluster.
When you apply your brakes, the cruise control
shuts off.{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use your 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 4-5. When road
conditions let you safely use it again, you can turn the
cruise control back on.

Setting Cruise Control
{CAUTION:
If you leave your cruise control 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 cruise control switch off until you
want to use cruise control.
The cruise control buttons
are located on left side of
the steering wheel.
I(On):This position turns on the system.
+ RES (Resume/Accelerate):Press this button to
make the vehicle accelerate or resume to a previously
set speed.
SET– (Set):Press this button to set the speed.
[(Cancel):Press this button to cancel cruise control.
Cruise control will not work if the parking brake is
set, or if the master cylinder brake uid level is low.
If the brakes are applied, the cruise control shuts off.
The cruise light on the instrument panel cluster comes
on after the cruise control has been set to the desired
speed.
1. Press the cruise control button.
2. Get up to the desired speed.
3. Press the SET– button located on the steering
wheel and release it.
4. Take your foot off the accelerator.
3-17

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)

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.

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.
