CADILLAC XLR 2009 1.G Owners Manual

Selecting the Follow Distance (GAP)
When the system detects a slower moving vehicle, it will
adjust your vehicle’s speed and maintain the following
distance (gap) selected.
Use the GAP button on
the steering wheel to
adjust the follow distance
between your vehicle
and other vehicles.
Press the top of the button to increase the distance or
the bottom of the button to decrease the distance.
The rst button press shows the current follow distance
setting on the HUD. The current following distance
setting is maintained until it is changed.
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 varies based
on vehicle speed. The faster the vehicle speed thefurther 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
prefer to travel at a following distance farther than
Adaptive Cruise Control allows, disengage the system
and drive manually.
A graphic on the HUD indicates the selected following
distance. This picture shows a maximum follow distance.
The vehicles will move closer together as you select a
smaller following distance.

Alerting the Driver
This symbol ashes on the
HUD and a warning beep
sounds 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 3-60for more information.
A malfunction is detected in the system. SeeDIC
Warnings and Messages on page 3-60for more
information.
SeeDefensive Driving on page 5-2.
{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.
Approaching and Following a Vehicle
This symbol only appears
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.
3-20

{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 automatically slows the vehicle
down when approaching a slower moving vehicle.
It then adjusts your speed to follow the vehicle in front
at the selected following distance. Your speed increases
or decreases to follow the vehicle in front of you, but
will not exceed the set speed. It may apply limited
braking, if necessary. When braking is active, the brake
lights come on. It may feel or sound different than if
you were applying the brakes yourself. This is normal.
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.
3-21

Low-Speed Deactivation
If your speed falls below 20 mph (32 km/h) while
following a vehicle ahead, Adaptive Cruise Control
begins to disengage. The driver alert symbol on
the HUD ashes and the warning beep sounds.
The driver must take action since Adaptive Cruise
Control will not slow the vehicle to a stop.
Passing a Vehicle
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 returns
to normal operation and the brakes can be applied,
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.
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 might operate differently in a
sharp curve. It might reduce your speed if the curve is
too sharp. The TIGHT CURVE message will also display
on the HUD. SeeHead-Up Display (HUD) on page 3-31
for more information.
3-22

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.Adaptive Cruise Control might detect a vehicle that is
not in your lane and apply the brakes.
Adaptive Cruise Control might 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.
3-23

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 while entering or on
exit ramps.
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 Controls on Hills
How well Adaptive Cruise Control works on hills
depends on your speed, vehicle load, traffic conditions,
and the steepness of the hills. It might not detect a
vehicle in your lane while driving on hills. While going
up steep hills, you might want to use the accelerator
pedal to maintain your vehicle speed. While going
downhill, you might have to brake to keep your vehicle
speed down. Applying the brake disengages the
system. You may choose not to use Adaptive Cruise
Control on steep hills.
Disengaging Adaptive Cruise Control
Apply the brake pedal or move the Adaptive Cruise
Control switch to off, to disengage the system. Adaptive
Cruise Control information does not appear on the
HUD while the system is not engaged.
3-24

Erasing Set Speed Memory
The set speed memory is erased when the Adaptive
Cruise Control switch or the ignition is turned off.
Other Messages
There are three messages that may appear on the DIC.
They are SERVICE RADAR CRUISE, CRUISE NOT
READY and CLEAN RADAR CRUISE. These messages
will only appear to indicate a problem with the Adaptive
Cruise Control. SeeDIC Warnings and Messages
on page 3-60for more information.
You may also see CRUISE SPEED LIMITED displayed
in the HUD. SeeHead-Up Display (HUD) on page 3-31
for more information.
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, located on the driver 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 tool 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 place.

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 to operate
the exterior lamps.
There are four positions:
O(Off):Turns off all lamps.
AUTO (Automatic):Sets the exterior lamps to
automatic mode. AUTO mode will turn the exterior
lamps on and off depending on how much light
is available outside the vehicle. Turning the band to
AUTO mode also enables the Adaptive Forward Lighting
system. SeeAdaptive Forward Lighting System on
page 3-28.To override AUTO mode, turn the control to off.
To reset to AUTO mode turn the control to exterior
lamps and then back to AUTO. Automatic mode will also
reset when your vehicle is turned off and then back
on again when the control is left in the AUTO position.
SeeTwilight Sentinel
®on page 3-29.
;(Parking Lamp):Turns on the parking lamps
together with the following:
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
The parking brake indicator light will come on and stay
on when the parking lamps are on with the engine
off and the ignition to ACC/ACCESSORY.
5(Headlamps):Turns on the headlamps, together
with the previously listed lamps and lights.
3-26

Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
approximately six seconds and the multifunction lever is
in the AUTO position. SeeExterior Lamps on page 3-26.
When the exterior lamp control has been turned off or is
in the parking lamp position and the wiper control is
on delay, low speed or high speed, the HEADLAMPS
SUGGESTED message will appear on the Driver
Information Center (DIC).
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off.
Headlamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver’s door is opened with the ignition off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. Fully functional DRL are required on all vehicles
rst sold in Canada.The DRL system comes on when the following
conditions are met:
It is still daylight and the ignition is on.
The exterior lamp control is in the off position.
The transmission is not in P (Park).
When DRL are on, only the front turn signal lamps are
on. No other exterior lamps such as the parking
lamps, taillamps, etc. are on when the DRL are used.
The instrument panel is not be lit up either.
When it is dark enough outside, the front turn signal
lamps turn off and normal low-beam headlamps turn on.
When it is bright enough outside, the regular lamps
go off, and the front turn signal lamps take over. If the
vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it takes about one minute for
the automatic headlamp system to change to DRL if
it is light outside. During that delay, the instrument panel
cluster might not be as bright as usual. Make sure the
instrument panel brightness knob is in the full bright
position. SeeInstrument Panel Brightness on page 3-30
for more information.
3-27

If it is dark enough outside and the exterior lamp control
is off, a HEADLAMPS SUGGESTED message displays
on the Driver’s Information Center (DIC). This message
informs the driver that turning on the exterior lamps is
recommended. SeeDIC Warnings and Messages on
page 3-60.
Turn the exterior lamp control off a second time,
or turn on the headlamps to turn off the HEADLAMPS
SUGGESTED message in the DIC. If the parking
lamps or the fog lamps were turned on instead, the
HEADLAMPS SUGGESTED message continues to
display.
The regular headlamp system should be turned on
when needed.
Adaptive Forward Lighting System
The Adaptive Forward Lighting System (AFS) swivels
the headlamps horizontally to provide greater road
illumination while turning. AFS will operate when the
vehicle speed is greater than 2 mph (3 km/h). AFS will
not operate when the transmission is in R (Reverse).
AFS is not immediately operable after starting the
vehicle; driving a short distance is required to calibratethe AFS. To enable AFS, set the exterior lamp switch
on the multifunction lever to the AUTO position.
Moving the switch out of the AUTO position will
deactivate the system. SeeExterior Lamps on
page 3-26.
Fog Lamps
Use fog lamps for better vision in foggy or misty
conditions.
The fog lamps control is located on the multifunction
lever next to the exterior lamp control.
#(Fog Lamps):Turn the band to turn the fog lamps on.
The fog lamp light appears on the instrument panel
cluster to indicate that the fog lamps and the parking
lamps are on.
If you turn the high-beam headlamps on, the fog lamps
will turn off. They will turn on again when you switch
to low-beam headlamps.
The ignition must be on for the fog lamps to operate.
The fog lamps will turn off when the ignition is turned off.
Some localities have laws that require the headlamps
to be on along with the fog lamps.
