engine CADILLAC XLR 2009 1.G Owners Manual

The proper replacement parts, uids, and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 7-11andMaintenance Replacement Parts
on page 7-13. When the 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
parts from your dealer/retailer.
Scheduled Maintenance
To maintain the ride, handling, and performance of this
vehicle, it is important that the rst tire rotation service be
performed when you notice unusual wear. Check tires for
ination pressures and wear. SeeTires on page 6-46.
If tire rotation is recommended for the vehicle, rotate tires.
SeeTire Inspection and Rotation on page 6-60.When the CHANGE OIL NOW message displays in the
Driver Information Center (DIC), service is required for
the vehicle. Have the vehicle serviced as soon as
possible within the next 600 miles (1 000 km). It is
possible that, if driving under the best conditions, the
engine oil life system may not indicate that vehicle
service is necessary for over a year. However, the engine
oil and lter must be changed at least once a year and at
this time the system must be reset. Your dealer/retailer
has trained service technicians who will perform this work
using genuine parts and reset the system.
If the engine oil life system is ever reset accidentally,
service the vehicle within 3,000 miles (5 000 km)
since the last service. Remember to reset the oil life
system whenever the oil is changed. SeeEngine Oil Life
System on page 6-18for information on the Engine
Oil Life System and resetting the system.

problem. Have the system inspected and repaired
and the fluid level checked. Add fluid if needed.
(b)Inspect wiper blades for wear, cracking, or
contamination. Clean the windshield and wiper blades, if
contaminated. Replace wiper blades that are worn or
damaged. See Windshield Wiper Blade Replacement
on page 6-45 and Windshield and Wiper Blades
on page 6-78 for more information.(c)Make sure the safety belt reminder light and safety
belt assemblies are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from
doing its job, have it repaired. Have any torn or frayed
safety belts replaced. Also see Checking the Restraint
Systems on page 1-52.
