2009 CADILLAC XLR instrument panel

Twilight Sentinel®
This feature can turn the lamps on and off for you.
A light sensor on top of the instrument panel makes the
Twilight Sentinel
®work, so be sure it is not covered.
With Twilight Sentinel
®you will see the following happen:
When it is dark enough outside, the front turn signal
lamps (DRL) will go off, and the headlamps and
parking lamps will come on. The other lamps that
come on with headlamps will also come on.
When it is bright enough outside, the headlamps will
go off, and the front turn signal lamps (DRL) will
come on, as long as the exterior lamp switch is in the
AUTO position.
If the vehicle is started in a dark garage, the automatic
headlamp system will come 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 may not be as bright as usual. Make sure the
instrument panel brightness control is in full bright
position. SeeInstrument Panel Brightness on page 3-30
for more information.You can idle the vehicle with the lamps off, even when
it is dark outside. After starting the vehicle, turn the
exterior lamp control band to off, then release it.
The lamps will remain off until you turn the control
band to off again.
Twilight Sentinel
®also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel®has turned
on the lamps when you turn off the ignition, the
lamps will remain on until:
The exterior lamp switch is moved from OFF to the
parking lamp position, or
the delay time selected has elapsed.
SeeDriver Information Center (DIC) on page 3-57to
select the delay time. You can also select no delay time.
If the ignition is turned off with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel
®delay will not occur. The lamps will turn off as
soon as the switch is turned off.
The regular headlamp system should be turned on
when needed.

Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have been
left on, the exterior lamps will turn off as soon as
the ignition is turned off or Retained Accessory Power
(RAP) is active. This protects against draining the
battery in case you have accidentally left the headlamps
or parking lamps on. The battery saver does not work
if the headlamps are turned on after the ignition switch is
turned to off.
If you need to leave the lamps on, use the exterior lamp
control to turn the lamps back on.

Battery Run-Down Protection
The vehicle has a feature to help prevent the battery
from being drained, in case the underhood lamp, vanity
mirror lamps, cargo lamps, reading lamps, console,
or glove box lamps are accidentally left on, or something
is left plugged into the accessory power outlet or
cigarette lighter. If any of the accessory lamps are
left on, they will automatically time-out after about
10 minutes. To reset the battery protection, all of the
above lamps must be turned off or the ignition must be
in the ACC/ACCESSORY position.
Head-Up Display (HUD)

If the HUD image is too bright, or too high in your
eld of view, it may take you more time to see
things you need to see when it is dark outside.
Be sure to keep the HUD image dim and placed
low in your eld of view.The Head-Up Display (HUD) allows you to see some of
the driver information that appears on the instrument
panel cluster.
The information may be displayed in English or metric

The air conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine.
This is normal.

the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.

Sensors
There are several sensors on the vehicle that measure
the temperature and the sun’s effect on passenger
comfort.
The solar sensor is located on top of the instrument panel
near the windshield. It monitors the solar heat then uses
the information to maintain the selected temperature
when operating in AUTO mode by initiating needed
adjustments to the temperature, the fan speed and the air
delivery system. The system may also supply cooler air to
the side of the vehicle facing the sun. The recirculation
mode will also be activated, as necessary. Do not cover
the sensor or the system will not work properly.
3-39

There is also a sensor located behind the front bumper.
This sensor reads the outside air temperature and
helps maintain the temperature inside the vehicle.
The outside temperature will be displayed in the
navigation system only when the engine is running.
Any cover on the front of the vehicle could give a false
reading of the temperature.
If the outside temperature goes up, the display
temperature will not change until:
The vehicle’s speed is above 15 mph (24 km/h)
for ve minutes.
The vehicle’s speed is above 32 mph (51 km/h)
for two and one-half minutes.
These delays prevent false readings. If the temperature
goes down, the outside temperature will be shown
when the vehicle is started. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
There is also an inside temperature sensor located to
the left of the ignition button. The automatic climate
control system uses this sensor to receive information,
so if it is blocked or covered, the system will not
function properly.
Outlet Adjustment
Use the thumbwheel to open or close the outlets.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into the vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the area around the base of the instrument
panel console and air path under the seats clear
of objects to help circulate the air inside of the
vehicle more effectively.
