instrument cluster CADILLAC XLR 2008 1.G User Guide

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 front of your vehicle. To change from English
to metric units, seeDriver Information Center (DIC)
on page 3-60.
The HUD consists of the following information:
Speedometer
Turn Signal Indicators
High-Beam Indicator Symbol
Tap-Up/Tap-Down Transmission Feature
Check Gages Icon
Adaptive Cruise Control Features and Indicators
Radio Features

Be sure to continue scanning your displays, controls
and driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel cluster, you may not see something important,
such as a warning light. Under important warning
conditions, the CHECK GAGES message will display in
the HUD. View your Driver Information Center (DIC)
for more information.The HUD controls are
located to the left of the
steering wheel.

Instrument Panel Cluster
Your instrument panel cluster and Driver Information Center (DIC) are designed to let you know at a glance how the
vehicle is running. You will know how fast you are going, about how much fuel you have left and many other things
you will need to know 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 will come 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 will
also come on and stay
on for several seconds,
then it will ash for
several more.
This chime and light is repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver’s
belt is already buckled, neither the chime nor the
light will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel cluster, which shows the airbag symbol. The
system checks the airbag’s electrical system for
malfunctions. The light tells you if 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 1-36.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
The light should go out
and the system is ready.
If the airbag readiness light stays on after you start
the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.
3-46

If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may be a
problem with the lights or the passenger sensing system.
See your dealer/retailer for service.
{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on,
it means that something may be wrong with
the airbag system. If this ever happens, have
the vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the airbag(s). SeeAirbag Readiness Light
on page 3-46for more on this, including
important safety information.
Charging System Light
This light will come on
briey when you turn
on the ignition, but
the engine is not running,
as a check to show
you it is working.
It should go out once the engine is running. If it stays
on, or comes on while you are driving, you may have a
problem with the charging system. A charging system
Driver Information Center (DIC) message may also
appear. SeeDIC Warnings and Messages on page 3-63
for more information. This light could indicate that you
have problems with a generator drive belt, or another
electrical problem. Have it checked right away.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such as
the radio and air conditioner.

Voltmeter Gage
When the vehicle is in
accessory mode, the
voltmeter shows the
voltage output of your
battery. When the engine
is running, it shows
the voltage output of
the charging system.
The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, your instrument panel
cluster and other systems may shut down. The Driver
Information Center (DIC) will read LOW VOLTAGE when
your vehicle is at 10 volts or below. Have it checked
right away. Driving with the voltmeter reading at
10 volts or below could drain your battery and disable
your vehicle.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
This light should come on when you start the engine.
If it does not come on then, have it xed so it will
be ready to warn you if there is a problem.
If this warning light stays on after you start the engine,
the parking brake may still be set or there could be
a brake problem. Refer toParking Brake on page 2-30
to see if it is set. If the parking brake is not set, have
your brake system inspected right away.
