Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 6-12for
the location of the engine air cleaner/lters.
When to Inspect the Engine Air
Cleaner/Filters
Inspect the air cleaner/lters at the MaintenanceII
intervals and replace them at the rst oil change after
each 50,000 mile (80 000 km) interval. SeeScheduled
Maintenance on page 7-4for more information.
If you are driving in dusty/dirty conditions, inspect the
lters at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filters
To inspect the air cleaner/lters, remove the lters from
the vehicle and lightly shake the lters to release
loose dust and dirt. If the lters remain caked with dirt,
new lters are required.To inspect or replace the lters, do the following:
1. Some XLR-V vehicles, have a single piece black
cover that snaps over the entire air cleaner
assembly. For vehicles with this cover, simply pull it’s
left/right sides toward the outside of the vehicle and
lift up to remove cover. Reinstall the cover when you
are nished inspecting/replacing the lters.
2. Move the clasps on the top of the engine air
cleaner/lter cover forward to unlatch the cover.

Scheduled Maintenance
To maintain the ride, handling, and performance of your
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 6-52.If
tire rotation is recommended for your vehicle, rotate tires.
SeeTire Inspection and Rotation on page 6-65.
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
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,
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. See
Engine Oil Life System on page 6-20for information on
the Engine Oil Life System and resetting the system.When the CHANGE OIL NOW message appears, the
following services, checks, and inspections are required:
❑Change engine oil and lter. SeeEngine Oil on
page 6-16. Reset oil life system. SeeEngine Oil Life
System on page 6-20.An Emission Control Service.
❑Visually check for any leaks or damage.
See footnote (a).
❑Inspect engine air cleaner lter. If necessary, replace
lter. SeeEngine Air Cleaner/Filter on page 6-22.
See footnote (h).
❑Check tires for ination pressures and wear. SeeTires
on page 6-52. If tire rotation is recommended for your
vehicle, rotate tires. SeeTire Inspection and Rotation
on page 6-65.
❑Inspect brake system.See footnote (l).
❑Check engine coolant and windshield washer uid
levels. If you have the 4.4L V8 supercharged engine,
check intercooler uid level. Add uid as needed.
❑Perform any needed additional services. See
“Additional Required Services” in this section.
❑Inspect suspension and steering components.
See footnote (n).
❑Inspect engine cooling system.See footnote (m).
❑Inspect wiper blades.See footnote (b).
❑Inspect restraint system components.
See footnote (c).
❑Lubricate body components.See footnote (d).
