2008 CADILLAC XLR turn signal

Twilight Sentinel®
Twilight Sentinel®can turn your 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 you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once you
leave the garage, it will take about one minute for the
automatic headlamp system to change to DRL if it is
light outside. During that delay, your instrument panel
cluster may not be as bright as usual. Make sure your
instrument panel brightness control is in full bright
position. SeeInstrument Panel Brightness on page 3-32
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, your lamps
will remain on until:
The exterior lamp switch is moved from OFF to
the parking lamp position, or
a delay time that you select has elapsed.
SeeDriver Information Center (DIC) on page 3-60to
select the delay time that you want. You can also select
no delay time.
If you turn off the ignition 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.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Battery Run-Down Protection
Your 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. position.
Head-Up Display (HUD)
{CAUTION:
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 your instrument
panel cluster.The information may be displayed in English or metric
units and appears as an image focused out toward

The following Adaptive Cruise Control (ACC) messages
may appear in the HUD:
CRUISE SPEED LIMITED:This message indicates that
your vehicle speed has been reduced below your set
speed due to ACC limitations. Your set speed is too high
and ACC cannot detect other vehicles at far enough
distances for the system to operate properly.
TIGHT CURVE:This message indicates that ACC has
reduced your vehicle speed due to a tight curve in
the road. Once the road straightens, ACC will return to
your selected set speed or follow distance setting.
See “Adaptive Cruise Control (ACC)” underTurn
Signal/Multifunction Lever on page 3-8for more
information.
You may also see an ACC active symbol, alert symbol
or vehicle ahead symbol. See “Adaptive Cruise
Control (ACC)” underTurn Signal/Multifunction Lever
on page 3-8for more information.Accessory Power Outlet(s)
The accessory power outlet can be used to connect
electrical equipment such as a cellular phone or
CB radio.
The accessory power outlet is located inside the
center console storage compartment, on the forward
left side.
To use the outlet, remove the tethered cap. When not
using it, always cover the outlet with the protective cap.
Notice:When using an accessory power outlet,
maximum electrical load must not exceed 20 amps.
Always turn off any electrical equipment when
not in use. Leaving electrical equipment on for
extended periods will drain your vehicle’s battery.
Certain electrical accessories may not be compatible

in blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information
on accessory power outlets.

The vehicle’s battery voltage is low. The battery
voltage must be above 10 volts for the keyless
access transmitter to be detected properly.
NO FOB, OFF OR RUN?

transmitter is not detected inside the vehicle while you
are trying to turn the ignition off. Your vehicle may be
near a strong radio antenna signal causing the keyless
access system to be jammed. The vehicle will remain in
ACCESSORY until the vehicle is turned off or is restarted,
or ve minutes has expired. If you turn the ignition off and
you cannot nd the keyless access transmitter, you will
not be able to restart the vehicle. The keyless access
transmitter needs to be inside of the vehicle in order for
the vehicle to start. SeeStarting the Engine on page 2-24

Passive Locking
This feature allows you to select whether the doors
automatically lock during normal vehicle exit. When the
ignition is turned off and all doors become closed,
the vehicle will determine how many keyless access
transmitters remain in the vehicle interior. If at least
one keyless access transmitter has been removed
from the interior of the vehicle, the doors will lock
after eight seconds.
For example, if there are two keyless access
transmitters in the vehicle and one is removed, the
other will be locked in. The keyless access transmitter
locked in the vehicle can still be used to start the vehicle
or unlock the doors, if needed. A person approaching
the outside of the locked vehicle without an authorized
keyless access transmitter, however, will not be able
to open the door, even with a transmitter in the vehicle.
