2008 CADILLAC XLR battery

OnStar service that involves location information about
your vehicle cannot work unless GPS satellite signals
are unobstructed and available in that place as well.
Your vehicle must have a working electrical system
(including adequate battery power) for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service to you at any particular time or place.
Some examples are damage to important parts of your
vehicle in an accident, hills, tall buildings, tunnels,
weather or wireless phone network congestion.
Your Responsibility
You may need to increase the volume of your radio
to hear the OnStar advisor. If the light next to the
OnStar buttons is red, this means that your system is
not functioning properly and should be checked by your
dealer/retailer. If the light appears clear (no light is
appearing), your OnStar subscription has expired.
You can always press the OnStar button to conrm
that your OnStar equipment is active.

Programming Universal Home
Remote — Fixed Code
If you have questions or need help programming
the Universal Home Remote System, call
1-866-572-2728 or go to www.learcar2u.com.
Most garage door openers sold before 1996 are
Fixed Code units.
Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before you begin. If you do not follow these actions,
the device will time out and you will have to repeat
the procedure.To program up to three devices:
1. To verify if you have a Fixed Code garage door
opener, remove the battery cover on your hand
held transmitter supplied by the manufacturer
of your garage door opener motor. If you see a
row of dip switches similar to the graphic above,
you have a Fixed Code garage door opener. If you
do not see a row of dip switches, return to the
previous section for Programming Universal Home
Remote – Rolling Code.
Your hand held transmitter may have between
eight to 12 dip switches depending on the brand of
transmitter.

Retractable Hardtop
The following procedures explain the proper operation
of the retractable hardtop. The retractable hardtop
will not operate if the valet lockout switch is on.
If the retractable hardtop is lowered or raised multiple
times, the engine should be running while doing so
to prevent drain on the vehicle’s battery.
{CAUTION:
When the retractable hardtop is opened or
closed, people can be injured by the parts that
move: the hardtop and its mechanism, the
trunk lid, and the side windows. Keep people
away from these parts when you are lowering
or raising the top.
Lowering the Retractable Hardtop
Notice:Leaving the retractable hardtop down and
exposing the interior of your vehicle to outdoor
conditions may cause damage. Always close
the retractable hardtop if leaving your vehicle
outdoors.
1. Park on a level surface and shift the transmission
into PARK (P).
2. The vehicle’s engine must be on or in Acc.
3. Lower both sun visors.
Notice:Raising or lowering the top while the
vehicle is in motion can cause damage to the top
or top mechanism. Make sure the vehicle is in
PARK (P) to lower or raise the top.
Notice:Lowering the top if it is damp, wet, or dirty
can cause stains, mildew, and damage to the
inside of your vehicle. Dry off the top before
lowering it.
4. Make sure that nothing or no one is on or around
the top. Make sure the trunk cargo cover is in
place with nothing on top or in front of the cargo
cover. SeeRear Storage Area on page 2-53
for more information. Also, make sure the valet
lockout switch is off.
2-54

After the top is fully raised, release the retractable
hardtop button. If you press the button again within
ve seconds, the windows will automatically close.
If your radio is on, you may notice a brief mute in
sound. This is normal and due to a new audio system
equalization being loaded for the vehicle with the
top raised.
Under certain conditions, the Driver Information
Center (DIC) may display messages regarding the
retractable hardtop. SeeDIC Warnings and Messages
on page 3-63for more information.
If the retractable hardtop does not operate, and there
are no messages displayed on the Driver Information
Center (DIC), then perform the “Power Window Initialize”
steps underPower Windows on page 2-17.Manually Raising the Retractable Hardtop
If your vehicle has a power loss, such as a dead battery,
you can still raise the top manually by doing the following:
1. Lower both sun visors and open both doors.
2. Use the key to open the trunk. SeeKeys on
page 2-3andTrunk on page 2-13for more
information.
3. Raise the trunk by hand.
4. Find the hydraulic
pump under the
carpet on the rear
driver’s side of
the trunk. Open the
valve by turning
it counterclockwise
with your hand
until it stops.
Notice:Pressing the retractable hardtop button
when the hydraulic pump valve is open could
damage the pump. Always close the hydraulic pump
valve after the retractable hardtop has been closed
manually.
