2009 CADILLAC XLR warning

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.

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.

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.

Passenger Compartment Air Filter
The passenger compartment air lter removes certain
particles from the air, including pollen and dust particles.
Reductions in airow, which may occur more often in
dusty areas, indicate that the lter may need to be
replaced early.
The lter should be replaced as part of the routine
scheduled maintenance. SeeScheduled Maintenance
on page 7-4for more information.
To check or replace the air lter, do the following:
1. With the hood open, unlatch and remove the
access panel.
The passenger compartment air lter and access
panel are located on the passenger side of the
engine compartment near the battery. SeeEngine
Compartment Overview on page 6-12for more
information on location.
2. Pull the old lter out of the housing.
3. Insert the new lter into the housing.
4. Reinstall the air lter access panel.
Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention
to the warning lights and gages could prevent injury.
Warning lights come on when there may be or is
a problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is started
to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
may be a problem, check the section that explains
what to do. Follow this manual’s advice. Waiting to
do repairs can be costly and even dangerous.

Instrument Panel Cluster
The instrument panel cluster and Driver Information Center (DIC) are designed to show how the vehicle is running.
It shows how fast the vehicle is going, about how much fuel is left and many other things needed to drive safely and
economically. The instrument panel cluster indicator warning lights, gages and DIC messages are explained on
the following pages.

Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime comes on for
several seconds to remind people to fasten their safety
belts, unless the driver’s safety belt is already buckled.
The safety belt light also
comes on and stay on for
several seconds, then
it ashes for several more.
This chime and light is repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver’s
safety belt is already buckled, neither the chime nor the
light comes on.
Airbag Readiness Light
The system checks the airbag’s electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners, the
airbag modules, the wiring and the crash sensing
and diagnostic module. For more information on the
airbag system, seeAirbag System on page 1-38.The airbag readiness light
ashes for a few seconds
when the engine is
started. If the light does
not come on then, have it
xed immediately.
{CAUTION:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inate in a crash, or they could even inate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also come
on. SeeDIC Warnings and Messages on page 3-60
for more information.
