2004 CADILLAC XLR Owners Manual

{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

Once ACC 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 ACC
is active. See
Head-Up
Display (HUD) on
page 3-27
for more
information.
Make sure the set speed is visible on the HUD so you
know the speed your vehicle will accelerate to if no
vehicle is detected in your path. Keep in mind speed
limits, surrounding traffic speeds and weather conditions
when adjusting your set speed.
Increasing Set Speed While Using ACC
There are two ways to increase 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 ACC 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 brie¯y to resume/increase. Each time
you do this, your vehicle set speed will increase by
1 mph (1.6 km/h). Your vehicle will not reach the
set speed until ACC determines there is no vehicle
in front of you. At that point, your vehicle speed
will increase to the set speed.
Decreasing Set Speed While Using ACC
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, brie¯y 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 ACC at a desired speed and then
you apply the brake. This will disengage the ACC.
But you do not need to reset it.
Once you are going about 25 mph (40 km/h) or more,
you can move the ACC switch brie¯y from on to
resume/increase. ACC will be engaged with the
previously chosen set speed.
3-13

Selecting the Follow Distance (GAP)
When ACC 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.
There are six follow distances to choose from. The
follow distance selection ranges from near to far
(1 second to 2 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 you 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 choose to travel at a distance farther than
ACC allows, disengage ACC and drive manually.
A graphic on the HUD indicates the selected follow
distance. This picture shows a maximum follow distance.
The vehicles will move closer as you select a smaller
follow distance.
3-14

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.
3-15

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 brie¯y,
ACC will not respond to vehicles you may see ahead.{CAUTION:
When the ACC radar is blocked by snow, ice,
or dirt, it may not detect a vehicle ahead until
it is very close. ACC may not have time to
slow your vehicle enough to avoid a collision.
Do not use ACC when the radar is blocked by
snow, ice, or dirt. Keep your radar clean. See
ªCleaning the Systemº later in this section.
ACC will automatically slow your vehicle down when
approaching a slower moving vehicle. ACC 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
never exceed the set speed. ACC 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.
3-16

Stationary or Very Slow-Moving Objects
{CAUTION:
ACC may not detect and react to stationary or
slow-moving objects in your lane. You could
crash into an object ahead of you. Do not use
ACC when approaching stationary or
slow-moving vehicles or other objects.
{CAUTION:
ACC may not detect and react to stationary or
slow-moving objects in your lane. ACC 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, ACC will begin to disengage.
The driver alert symbol on the HUD will ¯ash and the
warning beep will sound. The driver must take
action since ACC will not slow the vehicle to a stop.
Passing a Vehicle
If you need to increase speed to pass a vehicle, use the
accelerator pedal. While your foot is on the accelerator
pedal, the system will not automatically apply the
brakes. Once you pass the vehicle and remove your
foot from the accelerator pedal, ACC will return to
normal operation and be able to apply the brakes if
needed.
{CAUTION:
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 ACC.
3-17

Curves in the Road
{CAUTION:
Due to ACC 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.
ACC may reduce your speed in a curve if the curve is
too sharp. The TIGHT CURVE message will also display
on the HUD. See
Head-Up Display (HUD) on page 3-27for more information.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 on the HUD.
