2006 CADILLAC XLR automatic transmission fluid

HOT ENGINE–A/C OFF:This message displays when
the engine coolant becomes hotter than the normal
operating temperature. To avoid added strain on a hot
engine, the air conditioning compressor is automatically
turned off. When the coolant temperature returns to
normal, the A/C operation will automatically resume.
You can continue to drive your vehicle. If this message
continues to appear, have the system repaired by
your GM dealer as soon as possible to avoid
compressor damage.
ICE POSSIBLE:This message appears when the
outside air temperature is cold enough to create icy
road conditions.
LEFT DOOR AJAR:This message will display anytime
the vehicle engine is running, the transmission is not
in PARK (P) and the driver’s door is open or ajar.
A chime will sound when the vehicle’s speed is greater
than 3 mph (4.8 km/h).
LOW BRAKE FLUID:This message will display if the
vehicle is running to inform the driver that the brake
uid level is low. Have the brake system serviced
by your GM dealer as soon as possible. See “Brake
Fluid” underBrakes on page 6-35.LOW COOLANT:This message will appear when there
is a low level of engine coolant. Have the cooling
system serviced by your GM dealer as soon as possible.
SeeEngine Coolant on page 6-22.
LOW FUEL:This message will appear when the fuel
supply is less than 5 gallons (18.9 L) and the display is
turned off. A single chime will also sound when this
message is displayed.
LOW OIL LEVEL:For correct operation of the low oil
sensing system, your vehicle should be on a level
surface. A false LOW OIL LEVEL message may appear
if the vehicle is parked on a grade. The oil level
sensing system does not check for actual oil level if
the engine has been off for a short period of time,
and the oil level is never checked while the engine is
running. If the LOW OIL LEVEL message appears,
and your vehicle has been parked on level ground
with the engine off for at least 30 minutes, the oil level
should be checked by observing the oil dipstick. Prior
to checking the oil level, be sure the engine has been
off for a few minutes and your vehicle is on a level
surface. Then check the dipstick and add oil if
necessary. SeeEngine Oil on page 6-15.

Follow these steps to reinstall the covers to the engine
air cleaner/lter housings:
1. Align the four tabs located on the back of the cover
with the three slots on the back of the housing.
2. Push the cover slightly down and towards the
engine to engage the tabs in the slots and align the
two wing screws.
3. Engage and tighten the two clasps on the top of the
engine air cleaner/lter cover.
{CAUTION:
Operating the engine with the air cleaner/lter
off can cause you or others to be burned.
The air cleaner not only cleans the air; it helps
to stop ames if the engine backres. If it is
not there and the engine backres, you could
be burned. Do not drive with it off, and be
careful working on the engine with the air
cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre can
cause a damaging engine re. And, dirt can easily get
into your engine, which will damage it. Always have
the air cleaner/lter in place when you are driving.

How to Check Automatic
Transmission Fluid
It is not necessary to check the transmission uid level.
A transmission uid leak is the only reason for uid
loss. If a leak occurs, take the vehicle to the dealership
service department and have it repaired as soon as
possible.
There is a special procedure for checking and changing
the transmission uid. Because this procedure is
difficult, you should have this done at the dealership
service department. Contact your dealer for additional
information or the procedure can be found in the service
manual. To purchase a service manual, seeService
Publications Ordering Information on page 8-14.
Notice:Use of the incorrect automatic transmission
uid may damage your vehicle, and the damages
may not be covered by your warranty. Always
use the automatic transmission uid listed in
Recommended Fluids and Lubricants on page 7-11.
Change the uid and lter at the intervals listed in
Additional Required Services on page 7-6, and be sure
to use the uid listed inRecommended Fluids and
Lubricants on page 7-11.

Usage Fluid/Lubricant
Engine OilThe engine requires a special
engine oil meeting GM Standard
GM4718M. Oils meeting this
standard may be identied as
synthetic, and should also be
identied with the American
