2004 CADILLAC XLR cruise control

Some automatic downshifts may occur to maintain
minimum engine speed. This will only occur if you leave
the vehicle in too high of a gear range for the speed
the vehicle is traveling. For example, if you have been
driving in ®fth gear range and come to a stop without
manually downshifting, ®fth gear range will continue to
display in the HUD. The transmission will automatically
downshift to second gear. As you begin to drive
and accelerate, the transmission will automatically
upshift as quickly as possible to the selected ®fth
gear range.
In higher gear ranges, an automatic downshift will occur
if you press the accelerator pedal to the ¯oor. This
feature provides you with adequate acceleration
capabilities if you forget to downshift manually.
Automatic upshifts and downshifts will not display in
the HUD.
Driver shift control is available while the cruise control is
engaged. The shift behavior of the transmission will
react differently than when cruise control is not engaged.
This is not a malfunction and is necessary to allow
proper operation of the cruise control.
To return to fully automatic operation, move the shift
lever to the right and back into the AUTOMATIC
OVERDRIVE (D) position.Parking Brake
The parking brake pedal is
located to the left of the
regular brake pedal,
near the driver's door.
To set the parking brake, hold the regular brake pedal
down with your right foot and push the parking brake
pedal down with your left foot.
If the ignition is running, the parking brake indicator light
on the instrument panel cluster should come on. If it
does not, you need to have your vehicle serviced.

Windshield Washer
K
(Washer Fluid):The lever on the right side of the
steering column also controls the windshield washer.
There is a button at the end of the lever. To spray
washer ¯uid on the windshield, press the button and
hold it. The washer will spray until you release the
button. The wipers will continue to clear the window for
about six seconds after the button is released and
then stop or return to your preset speed.
Your vehicle also has headlamp washers. Every fourth
time the washer ¯uid button is pressed, washer ¯uid
will clean the headlamps.
{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.If the ¯uid in the windshield washer ¯uid reservoir is
low, the message LOW WASHER FLUID will appear on
the Driver Information Center (DIC) display. It will
take 60 seconds after the bottle is re®lled for this
message to turn off. For information on the correct
washer ¯uid mixture to use, see
Windshield Washer
Fluid on page 5-33andRecommended Fluids and
Lubricants on page 6-11.
Adaptive Cruise Control (ACC)
Be sure to read this entire section before using this
feature.
The system operates on a radio frequency subject to
Federal Communications Commission (FCC) Rules and
with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
3-9

This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modi®cations 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 and is not a safety system. ACC
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
328 ft (100 m), and operates at speeds above
25 mph (40 km/h). When it is engaged by the driver,
ACC can apply limited braking or acceleration of
the vehicle automatically to maintain a selected follow
distance to the vehicle ahead. ACC 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 ACC, apply the brake. If there is
no vehicle in your path, your vehicle will react like
traditional cruise control.
{CAUTION:
ACC will not apply hard braking or bring the
vehicle to a complete stop. ACC will not
respond to stopped vehicles, pedestrians or
animals. When you are approaching a vehicle
or object, ACC 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 4-2.
3-10

{CAUTION:
·On winding roads, ACC may not detect a
vehicle ahead. You could crash into a
vehicle ahead of you. Do not use ACC on
winding roads.
·In heavy stop-and-go traffic, ACC may not
have time to slow your vehicle enough to
avoid a collision because of the rapidly
changing traffic conditions. Do not use
ACC in heavy stop-and-go traffic.
·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 visibility is low, such as in fog, rain
or snow, you can not tell how far away
things are and ACC 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.Some of the ACC controls
are located on the end of
the multifunction lever.
9(Off):This position turns the system off.
R(On):This position turns the system on.
S(Resume/Increase):Push the switch to this symbol
to make the vehicle resume to a previously set speed
or to increase the set speed when ACC is already active.
T(Set/Decrease):Press this button to set the
speed or to decrease the set speed when ACC is
already active.

Engaging ACC 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.
{CAUTION:
If you operate ACC without your Head-up
Display (HUD) on and properly adjusted,
your ACC settings will not be visible. You
could forget your settings and be startled by
ACC response and even lose control. Keep
your HUD on and properly adjusted when
using ACC.ACC 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 ACC, do the following:
1. Make sure the Head-Up Display (HUD) is on and
properly adjusted. See
Head-Up Display (HUD) on
page 3-27for more information.
2. Move the ACC switch to on.
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.
3-12

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:
·ACC 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 ACC from operating.
See
DIC Warnings and Messages on page 3-57for
more information.
·A malfunction is detected in the ACC system. See
DIC Warnings and Messages on page 3-57for
more information.
See
Defensive Driving on page 4-2for more information.
{CAUTION:
Adaptive Cruise Control has only limited
braking ability to slow your vehicle. In some
cases, ACC 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 4-2.
