2005 Cadillac XLR Owner ManualM

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 3-64andEngine Oil on page 6-13.
{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil. United States

DIC Warnings and Messages
These messages will appear if there is a problem
sensed in one of your vehicle’s systems. You must then
press RESET to clear the display screen for further
use. However, be sure to take any message that
appears on the display screen seriously and remember
that pressing the RESET button will only make the
message disappear, not the problem.
DIC messages can also be displayed in English,
French, German, Italian and Spanish.
ABS ACTIVE:When your anti-lock system is adjusting
brake pressure to help avoid a braking skid, the ABS
ACTIVE message will be displayed.
Slippery road conditions may exist if this message is
displayed, so adjust your driving accordingly. The
message may stay on for a few seconds after the
system stops adjusting brake pressure.
BATTERY SAVER ACTIVE:This message is displayed
when the vehicle has detected that the battery voltage
is dropping beyond a reasonable point. The battery
saver system will start reducing certain features of the
vehicle that you may not be able to notice. At the
point that features are disabled, this message is
displayed. It means that the vehicle is trying to save the
charge in the battery. Turn off unnecessary accessories
to allow the battery to recharge.CHANGE OIL NOW:This means that the life of the
engine oil has expired. SeeScheduled Maintenance on
page 7-4. After an oil change, the Oil Life Indicator
must be reset. SeeOil Life Indicator on page 3-77and
Engine Oil Life System on page 6-16.
CHARGE SYSTEM FAULT:This message will display
when a problem with the charging system has been
detected. Have your vehicle serviced by your GM dealer.
CHECK GAS CAP:This message will appear if the
gas cap has not been fully tightened. You should
recheck your gas cap to ensure that it is on properly.
CLEAN RADAR CRUISE:This message indicates the
ACC system is disabled because the radar is blocked and
cannot detect vehicles in your path. It may also activate
during heavy rain or due to road spray. To clean the
system, see “Adaptive Cruise Control (ACC)” underTurn
Signal/Multifunction Lever on page 3-7.
CLOSE CARGO DIVIDER:This message indicates that
the cargo divider is not in place. Open the trunk and
make sure the cargo divider is secure and no objects are
on the divider. SeeRear Storage Area on page 2-44
for more information.

Automatic Transmission Fluid
How to Check
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 your dealer
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 your dealer 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 8-12.
Notice:Use of automatic transmission uid labeled
other than DEXRON
®-III, Approved for the
H-Specication, may damage your vehicle, and the
damages may not be covered by your warranty.
Always use automatic transmission uid labeled
DEXRON
®-III, Approved for the H-Specication.Change both the uid and lter every 50,000 miles
(80 000 km) if the vehicle is mainly driven under one of
these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
High performance operation.
If you do not use your vehicle under one of these
conditions, change the uid and lter every
100,000 miles (166 000 km).
SeeScheduled Maintenance on page 7-4for the proper
service intervals for the transmission uid and lter.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst, if you add only
DEX-COOL
®extended life coolant.
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating
on page 6-23.

{CAUTION:
Performing maintenance work on a vehicle can
be dangerous. In trying to do some jobs, you
can be seriously injured. Do your own
maintenance work only if you have the
required know-how and the proper tools and
equipment for the job. If you have any doubt,
see your GM Goodwrench dealer to have a
qualied technician do the work.Some maintenance services can be complex. So,
unless you are technically qualied and have the
necessary equipment, you should have your GM
Goodwrench dealer do these jobs.
When you go to your GM Goodwrench dealer for your
service needs, you will know that GM-trained and
supported service technicians will perform the work
using genuine GM parts.
If you want to purchase service information, seeService
Publications Ordering Information on page 8-12.
Owner Checks and Services on page 7-8tells you what
should be checked, when to check it and what you can
easily do to help keep your vehicle in good condition.
The proper replacement parts, uids and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 7-11andNormal Maintenance Replacement
Parts on page 7-13. When your vehicle is serviced,
make sure these are used. All parts should be replaced
and all necessary repairs done before you or anyone
else drives the vehicle. We recommend the use of
genuine GM parts.
7-3

Scheduled Maintenance
When the CHANGE OIL NOW message in the Driver
Information Center (DIC) comes on, it means that service
is required for your vehicle. Have your vehicle serviced as
soon as possible within the next 600 miles (1 000 km). It
is possible that, if you are driving under the best
conditions, the engine oil life system may not indicate that
vehicle service is necessary for over a year. However,
your engine oil and lter must be changed at least once a
year and at this time the system must be reset. Your GM
Goodwrench dealer has GM-trained service technicians
who will perform this work using genuine GM parts and
reset the system.
If the engine oil life system is ever reset accidentally, you
must service your vehicle within 3,000 miles (5 000 km)
since your last service. Remember to reset the oil life
system whenever the oil is changed. SeeEngine Oil Life
System on page 6-16for information on the Engine Oil
Life System and resetting the system.When the CHANGE OIL NOW message appears,
certain services, checks and inspections are required.
Required services are described in the following for
“MaintenanceI” and “MaintenanceII.” Generally,
it is recommended that your rst service be
MaintenanceI, your second service be MaintenanceII
and that you alternate MaintenanceIand MaintenanceII
thereafter. However, in some cases, MaintenanceII
may be required more often.
MaintenanceI— Use MaintenanceIif the CHANGE
OIL NOW message comes on within 10 months since the
vehicle was purchased or MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the message comes on
10 months or more since the last service or if the
message has not come on at all for one year.
