Scheduled Maintenance
To maintain the ride, handling, and performance of
the vehicle, it is important that the rst tire rotation
service be performed when the vehicle has 5,000 to
8,000 miles (8 000 to 13 000 km). Check tires for
ination pressures and wear. SeeTires on page 5-48.
Rotate tires. SeeTire Inspection and Rotation on
page 5-65and “Tire Wear Inspection” inAt Least Once
a Month on page 6-9.
When the CHANGE ENGINE OIL SOON 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 5-16for information on the Engine
Oil Life System and resetting the system.When the CHANGE ENGINE OIL SOON message
appears, the following services, checks, and inspections
are required:
❑Change engine oil and lter. SeeEngine Oil on
page 5-13. Reset oil life system. SeeEngine Oil Life
System on page 5-16.An Emission Control Service.
❑Visually check for any leaks or damage.
See footnote (k).
❑Inspect engine air cleaner lter. If necessary, replace
lter. SeeEngine Air Cleaner/Filter on page 5-17.
See footnote (m).
❑Rotate tires and check ination pressures and wear.
SeeTire Inspection and Rotation on page 5-65and
“Tire Wear Inspection” inAt Least Once a Month on
page 6-9.
❑Inspect brake system.See footnote (a).
❑Check engine coolant and windshield washer uid
levels and add uid as needed.
❑Perform any needed additional services.
See “Additional Required Services” in this section.
❑Inspect suspension and steering components.
See footnote (b).
❑Inspect engine cooling system.See footnote (c).
❑Inspect wiper blades.See footnote (d).
❑Inspect restraint system components.See footnote (e).
❑Lubricate body components.See footnote (f).
❑Check transmission uid level and add uid
as needed.

Maintenance Footnotes
(a)Visually inspect brake lines and hoses for proper
hook-up, binding, leaks, cracks, chafing, etc. Inspect disc
brake pads for wear and rotors for surface condition.
Inspect other brake parts, including calipers, parking
brake, etc.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing parts or
signs of wear. Inspect power steering lines and hoses
for proper hook-up, binding, leaks, cracks, chafing, etc.
(c)Visually inspect hoses and have them replaced if they
are cracked, swollen, or deteriorated. Inspect all pipes,
fittings and clamps; replace with genuine parts as
needed. To help ensure proper operation, a pressure test
of the cooling system and pressure cap and cleaning the
outside of the radiator and air conditioning condenser is
recommended at least once a year.
(d)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 5-46 and Windshield and Wiper Blades on
page 5-91 for more information.
(e)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 1-70.
(f)Lubricate all key lock cylinders. Lubricate all hinges
and latches, including those for the hood, rear
compartment, glove box door, and console door.
More frequent lubrication may be required when exposed
to a corrosive environment. Applying silicone grease on
weatherstrips with a clean cloth will make them last
longer, seal better, and not stick or squeak.
(g)If driving regularly under dusty conditions, the filter
may require replacement more often.
(h)Change automatic transmission fluid and filter if the
vehicle is mainly driven under one or more of these
conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Professional vehicle uses, such as limousine
service.
Uses such as high performance operation.
