2008 CADILLAC XLR Owners Manual

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
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.
3-23

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 3-33
for 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.
3-24

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.
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.
3-25

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.
3-26

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 3-63for more information.
You may also see CRUISE SPEED LIMITED displayed
in the HUD. SeeHead-Up Display (HUD) on page 3-33
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’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 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 with this
symbol on it to operate the exterior lamps.
The exterior lamp band has four positions:
O(Off):Turning the band to this position turns off
all lamps.
AUTO (Automatic):Turning the band to this position
sets the exterior lamps in 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 3-30.
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 3-31.
;(Parking Lamp):Turning the band to this position
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.
5(Headlamps):Turning the control to this position
turns on the headlamps, together with the previously
listed lamps and lights.
3-28

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 3-28.
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. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
DRL are required on all vehicles rst sold in Canada.The DRL system makes the front turn signal lamps
come 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 PARK (P).
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. Your
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 you start your
vehicle in a dark garage, the automatic headlamp system
comes on immediately. Once you leave 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 3-32for more information.
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 3-63.
3-29

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.
As with any vehicle, you should turn on the regular
headlamp system 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 REVERSE (R).
AFS is not immediately operable after starting the
vehicle; driving a short distance is required to calibrate
the 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 3-28.
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):Turning the band to this position will
turn the fog lamps on.
When you turn the fog lamps on, the fog lamp light will
appear 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.
