2007 CADILLAC XLR brake

Cruise Control
Your vehicle has cruise control.
9(Off):This position
turns the system off.
R(On):This position turns the system on.
+ (Resume/Accelerate):This position makes the
vehicle accelerate or resume to a previously
set speed.
T(Set):Press this button at the end of the
lever to set the speed.
With cruise control, you can maintain a speed of
about 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This can
really help on long trips. Cruise control does not
work at speeds below about 25 mph (40 km/h).Cruise control will not work if the parking brake is
set, or if the master cylinder brake uid level is low.
{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 has the traction control system and
it begins to limit wheel spin while cruise control
is on, the cruise control will automatically
disengage. SeeTraction Control System (TCS) on
page 329. When road conditions allow you to
safely use it again, you may turn 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.
1. Move the cruise control switch to on.
2. Get up to the speed desired.
3. Press the set button at the end of the lever
and release it.
4. Take your foot off the accelerator pedal.The cruise symbol on
the instrument panel
cluster will be lit
when the cruise control
is engaged.
Resuming a Set Speed
Suppose you set your cruise control at a desired
speed and then you apply the brake. This
disengages the cruise control. But it does not
need to be reset.
Once you are going about 25 mph (40 km/h) or
more, you can move the cruise control switch
briey from on to resume/accelerate.
You will go right back up to your chosen speed
and stay there.
If you hold the switch at resume/accelerate the
vehicle will keep going faster until you release the
switch or apply the brake. Do not hold the
switch at resume/accelerate, unless you want the
vehicle to go faster.
148

Using Cruise Control on Hills
How well your cruise control works on hills
depends upon your speed, load and the steepness
of the hills. When going up steep hills, you
might have to step on the accelerator pedal to
maintain your speed. When going downhill,
you might have to brake or shift to a lower gear to
keep your vehicle’s speed down. Of course,
applying the brake turns off the cruise control.
Many drivers nd this to be too much trouble and
do not use cruise control on steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:
Step lightly on the brake pedal
Move the cruise control switch to off
Erasing Speed Memory
Turning off the cruise control or the ignition, will
erase your cruise control set speed memory.

Adaptive Cruise Control is an enhancement to
traditional cruise control and is not a safety
system. 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 328 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. Braking is limited to 0.3 g’s (2.95 m/sec2)
of deceleration, which is comparable to moderate
application of the vehicle’s brakes. To disengage
Adaptive Cruise Control, apply the brake. If there is
not a vehicle 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, see
Defensive Driving on page 322.

3. Get up to the speed you want.
4. Press in the set button at the end of the lever
and release it.
5. 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.
This symbol will appear
on the Head-Up Display
(HUD) to indicate that
Adaptive Cruise
Control is active.
SeeHead-Up Display (HUD) on page 171for
more information.
Make sure the set speed is visible on the HUD so
you know the speed your vehicle will accelerate to if
a vehicle is not detected in your path. 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 329andStabiliTrak
®System on page 331.
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 at the end of the lever,
then release the button and the accelerator
pedal. You will now cruise at the higher speed.
Move the Adaptive Cruise Control switch from
on to resume/increase. Hold it there until the
desired set speed is displayed in the HUD,
then release the switch. To increase your set
speed in very small amounts, move the
switch briey to resume/increase. Each time
you do this, your vehicle set speed will
increase by 1 mph (1.6 km/h).
154

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
Adaptive Cruise Control
Press in the set/decrease button on the end of the
lever until you reach the lower speed you want,
then release it.
To slow down in very small amounts, briey press
the set/decrease button. Each time you do this,
your set speed will be 1 mph (1.6 km/h) slower.
Resuming a Set Speed
Suppose you set your Adaptive Cruise Control at
a desired speed and then you apply the brake.
This will disengage the Adaptive Cruise Control.
But you do not need to reset it.
Once you are going about 25 mph (40 km/h) or
more, you can move the Adaptive Cruise Control
switch briey from on to resume/increase.
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 GAP button on
the steering wheel to
adjust the follow
distance.
Press the top of the button to increase the
distance or the bottom of the button to decrease
the distance. The rst button press will show
you the current follow distance setting on the HUD.
Your current follow distance setting will be
maintained until you change it.
155

Alerting the Driver
The alert symbol will
ash on the HUD and a
warning beep will
sound when driver
action is required.
Driver action is required 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 206for more
information.
A malfunction is detected in the system. See
DIC Warnings and Messages on page 206
for more information.
SeeDefensive Driving on page 322for more
information.
{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. See
Defensive Driving on page 322.
157

Approaching and Following a Vehicle
The vehicle ahead
symbol will only appear
on the HUD when a
vehicle ahead 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 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. The system 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.
