2007 CADILLAC XLR V battery

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.

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.

As always, drivers should use care when backing
up a vehicle. Always look behind you, being
sure to check for other vehicles, obstructions and
blind spots.
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 with the accessory power outlet and
could result in blown vehicle or adapter fuses.
If you experience a problem, see your dealer for
additional information on accessory power outlets.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should. The
repairs would not be covered by your
warranty. Do not use equipment exceeding
maximum amperage rating of 20 amperes.
Check with your dealer before adding electrical
equipment.
When adding electrical equipment, be sure to
follow the installation instructions included with the
equipment.
We recommend that you see a qualied technician
or your dealer for the proper installation of your
equipment.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or
accessory bracket from the plug because the
power outlets are designed for accessory
power plugs only.

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 your 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 your vehicle more effectively.
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 465for 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’s
side of the engine compartment near the
battery. SeeEngine Compartment Overview
on page 374for 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.

If the word OFF or the off symbol is lit on the
passenger airbag status indicator, it means that
the passenger sensing system has turned off
the passenger’s airbags. SeePassenger Sensing
System on page 53for more on this, including
important safety information.
If, after several seconds, all 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 for service.
{CAUTION:
If the airbag off indicator and the airbag
readiness light ever come on together, 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 seat may not have
the protection of the airbag. SeeAirbag
Readiness Light on page 188.
Charging System Light
When you turn the
engine on, this light will
come on briey to
show that the generator
and battery charging
systems are working
properly.
If this light stays on, your vehicle needs service.
You should take your vehicle to the dealer at once.
To save your battery until you get there, turn off
all accessories. SeeDIC Controls and Displays on
page 204for more information.

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 97to see if it is set. If the parking
brake is not set, have your brake system
inspected right away.

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 366. Poor fuel
quality will cause the engine not to run as
efficiently as designed. You may notice this as
stalling after start-up, stalling when you put
the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration. (These
conditions may go away once the engine is
warmed up.) This will be detected by the system
and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at
least one full tank of the proper fuel to turn the
light off.
If none of the above steps have made the light
turn off, your dealer can check the vehicle.
Your dealer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
To perform a check engine light bulb check with the
keyless ignition, make sure the transmitter fob is in
the passenger compartment. SeeIgnition Positions
on page 88. Press the bottom of the Acc. button on
the instrument panel and hold the button down for
ve seconds. The instrument panel, including the
check engine light, will light up and the ignition will
be on, but the engine will not start — if you press
the bottom of the Acc. button only briey, less than
ve seconds, the accessory power mode will be
turned on, but not the ignition. After the bulb check,
be sure to press and release the Acc. button again
to turn the ignition off and avoid draining the
vehicle’s battery.
199

Your vehicle will not pass this inspection if the
OBD (on-board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system. The vehicle
would be considered not ready for inspection.
This can happen if you have recently replaced the
battery or if the battery has run down. The
diagnostic system is designed to evaluate critical
emission control systems during normal driving.
This may take several days of routine driving.
If you have done this and your vehicle still does
not pass the inspection for lack of OBD system
readiness, your dealer can prepare the vehicle for
inspection.Engine Oil Pressure Gage
The engine oil pressure gage shows the engine oil
pressure in psi (pounds per square inch) or kPa
(kilopascals) when the engine is running.
Oil pressure should be 20 to 80 psi
(140 to 550 kPa). In certain situations such as
long, extended idles on hot days, it could read as
low as 6 psi (40 kPa) and still be considered
normal. It may vary with engine speed, outside
temperature and oil viscosity. The Driver
Information Center (DIC) may display messages
regarding the oil condition. SeeDIC Warnings and
Messages on page 206andEngine Oil on
page 377.
