2007 CADILLAC XLR ignition

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.
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.
168

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 170for 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 203
to 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.
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 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.
169

Reading Lamps
Your inside rearview mirror includes two reading
lamps. The lamps will go on when a door is
opened. When the doors are closed, each lamp
can be turned on individually by pressing the
button for that lamp.
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 20 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 front of your vehicle. To change
from English to metric units, seeDriver Information
Center (DIC) on page 203.
171

As light shines out from the HUD, it is possible for
light to shine back in. In rare occurrences,
when the sun is at a specic angle and position,
the sun’s rays can shine back into the HUD. When
this occurs, the display device within the HUD
will be temporarily illuminated. The event will end
when the vehicle’s angle to the sun changes.
Clean the inside of the windshield as needed to
remove any dirt or lm that reduces the sharpness
or clarity of the HUD image.
To clean the HUD, spray household glass cleaner
on a soft, clean cloth. Wipe the HUD lens gently,
then dry it. Do not spray cleaner directly on the lens
because the cleaner could leak into the unit.
If the ignition is on and you cannot see the HUD
image, check to see if:
Something is covering the HUD unit.
The brightness is adjusted properly.
The HUD image is adjusted to the proper
height.
Ambient light in the direction your vehicle is
facing is low.
A fuse is blown. SeeFuses and Circuit
Breakers on page 453.Keep in mind that your windshield is part of the
HUD system. SeeWindshield Replacement
on page 412.
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 141for 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 141for more
information.
174

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 you start the vehicle. 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 you block or cover
it, the system will not function properly.
Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate control
system is used properly. There are two modes to
clear fog or frost from your windshield. Use the
oor/defog mode to clear the windows of fog or
moisture and warm the passengers. Use defrost to
remove fog or frost from the windshield more
quickly.
-(Floor/Defog):Press the mode button until the
defog mode appears on the display. This mode
directs the air between the windshield, oor outlets
and side windows. When you select this mode,
the system turns off recirculation and runs the air
conditioning compressor unless the outside
temperature is near or below freezing.
1(Defrost):Press this button to direct most of
the air to the windshield, with some air directed
to the side windows. In this mode, the system will
automatically turn off the recirculation and run
the air conditioning compressor, unless the outside
temperature is near or below freezing. Do not
drive the vehicle until all the windows are clear.

Speedometer and Odometer
Your speedometer lets you see your speed in
either miles per hour (mph) or kilometers per
hour (km/h).
There is only one scale for mph and km/h. Use
the Driver Information Center (DIC) controls
to switch between mph and km/h. SeeDIC
Controls and Displays on page 204for more
information. The cluster will calculate the proper
speed and move the needle to the correct position.
Either the MPH or the km/h telltale will illuminate,
depending on which measurement you choose.
The odometer is part of the Driver Information
Center (DIC). SeeDIC Controls and Displays on
page 204for more information.
Trip Odometer
The trip odometer is part of the Driver Information
Center (DIC). SeeDIC Controls and Displays
on page 204for more information.
Tachometer
The tachometer displays the engine speed in
thousands of revolutions per minute (rpm).
Fuel will shut off at about 6700 rpm.If you continue to drive your vehicle at the fuel
shut off rpm, you could damage your engine. Be
sure to operate your vehicle below the fuel
shut off rpm or reduce your rpm quickly when the
fuel shuts off.
Safety Belt Reminder Light
When the ignition button is pressed to START, a
chime will be provided for several seconds to
remind people to buckle their safety belts. The
driver safety belt light will also be provided and stay
on for several seconds, then it will ash for several
more. You should buckle your seat belt.
This chime and light will
be repeated if the driver
remains unbuckled
and the vehicle
is in motion.
If the driver’s belt is buckled, neither the chime nor
the light will be provided.

If the light comes on while you are driving and you
have a LOW BRAKE FLUID message showing
on the DIC, pull off the road and stop carefully.
You may notice that the pedal is harder to
push. Or, the pedal may go closer to the oor. It
may take longer to stop. If the light is still on, have
the vehicle towed for service. SeeTowing Your
Vehicle on page 359.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System Warning
Light
With the Anti-Lock
Brake System (ABS),
this light will come
on when your engine is
started and may stay
on for several seconds.
That is normal.
If the light stays on, turn the ignition off or if the light
comes on when you are driving, stop as soon as
possible and turn the ignition off. Then start the
engine again to reset the system. If the light still
stays on, or comes on again while you are driving,
your vehicle needs service. If the regular brake
system warning light is not on, you still have brakes,
but you do not have anti-lock brakes. If the regular
brake system warning light is also on, you do not
have anti-lock brakes and there is a problem with
your regular brakes. See “Service ABS” underDIC
Warnings and Messages on page 206.
The ABS warning light will come on briey when
you turn the ignition on. This is normal. If the
light does not come on then, have it xed so it will
be ready to warn you if there is a problem.

Tire Pressure Light
This light will come on
briey when you turn
the ignition on.
This light will also come on when one or more of
your tires are signicantly underinated.
A LOW TIRE PRESS DIC message will
accompany the light, seeOther Messages on
page 219for more information.Stop and check your tires as soon as it is safe to do
so. If underinated, inate to the proper pressure.
SeeTires on page 413for more information.
This light will ash for about 60 seconds and then
turn on solid if a problem is detected with the
Tire Pressure Monitor system.
SeeTire Pressure Monitor System on page 423
for more information.
