CADILLAC XLR 2005 1.G Owners Manual

The set speed is selected by the driver. This is the
speed you will travel if there is not a vehicle detected in
your path.
To set Adaptive Cruise Control, do the following:
1. Make sure the Head-Up Display (HUD) is on and
properly adjusted. SeeHead-Up Display (HUD) on
page 3-34for more information.
2. Move the 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.
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 3-34for 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 5-8and
StabiliTrak
®System on page 5-10. 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).
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.
3-20

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.
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 Adaptive Cruise Control allows, disengage
the system 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.
3-21

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 3-64for more information.
A malfunction is detected in the system. SeeDIC
Warnings and Messages on page 3-64for more
information.
SeeDefensive Driving on page 5-2for 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. SeeDefensive Driving
on page 5-2.
3-22

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.
3-23

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 on the HUD
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.
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, Adaptive Cruise Control
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 Adaptive Cruise Control.
3-24

Curves in the Road
{CAUTION:
Due to Adaptive Cruise Control 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.
Adaptive Cruise Control may operate differently in a
sharp curve.
The system may reduce your speed in a curve if the
curve is too sharp. The TIGHT CURVE message will also
display on the HUD. SeeHead-Up Display (HUD) on
page 3-34for more information.When following a vehicle and entering a curve, Adaptive
Cruise Control 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.
3-25

Adaptive Cruise Control may detect a vehicle that is not
in your lane and apply the brakes.
Adaptive Cruise Control may, occasionally, provide a
driver alert and/or braking that you consider unnecessary.
It could respond to signs, guardrails and other stationary
objects when entering or exiting a curve. This is normal
operation. Your vehicle does not need service.
Highway Exit Ramps
{CAUTION:
Adaptive Cruise Control may lose track of the
vehicle ahead and accelerate up to your set
speed while entering or on highway exit
ramps. You could be startled by this
acceleration and even lose control of the
vehicle. Disengage Adaptive Cruise Control
before entering a highway exit ramp. Do not
use Adaptive Cruise Control on exit ramps.
3-26

Other Vehicle Lane Changes
If another vehicle enters the same lane as you, Adaptive
Cruise Control will not detect the vehicle until it is
completely in the lane. Be ready to take action and apply
the brakes yourself.
Using Adaptive Cruise Control on Hills
How well Adaptive Cruise Control will work on hills
depends on your speed, vehicle load, traffic conditions
and the steepness of the hills. It may not detect a
vehicle in your lane while driving on hills. When going
up steep hills, you may want to use the accelerator
pedal to maintain your speed.When going downhill, you may have to brake to keep
your speed down. Applying the brake disengages
the system. You may choose not to use Adaptive Cruise
Control on steep hills.
Disengaging Adaptive Cruise Control
To disengage the system, apply the brake pedal or
move the Adaptive Cruise Control switch to off. Adaptive
Cruise Control information will not appear on the HUD
when the system is not engaged.
Erasing Set Speed Memory
When you turn the Adaptive Cruise Control switch or
the ignition off, the set speed memory is erased.
Other Messages
There are three messages that may appear in the
Driver Information Center (DIC). They are SERVICE
RADAR CRUISE, CRUISE NOT READY and CLEAN
RADAR CRUISE. These messages will only appear
to indicate a problem if Adaptive Cruise Control is active.
SeeDIC Warnings and Messages on page 3-64for
more information.
You may also see CRUISE SPEED LIMITED displayed
in the HUD. SeeHead-Up Display (HUD) on page 3-34
for more information.
3-27

Cleaning the System
The radar can become blocked by snow, ice or dirt. If so,
you may need to turn off the engine and clean the lens.
The lens is located on the driver’s side of the front fascia.
Clean the surface with a 50/50 mixture of isopropyl
alcohol and water on a dampened cloth. After cleaning
the fascia lens, try to engage Adaptive Cruise Control. If
this does not x the problem, you may have to remove
the fascia lens and clean the inside of the fascia lens and
radar lens.To clean the inside of the fascia lens and radar lens,
insert a screwdriver or similar object into one of the small
slots on the inboard side of the lens and pop the lens out.
Clean the surface with a 50/50 mixture of isopropyl
alcohol and water on a dampened cloth. After cleaning
the lens, set the lens back in place and press until it
snaps in.
Exterior Lamps
The exterior lamp control is located to the left of the
steering wheel on the multifunction lever.
O(Exterior Lamp Control):Turn the band with this
symbol on it to operate the exterior lamps.
