Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service for
new tires be performed when they have 8 000 to
13 000 km (5,000 to 8,000 miles). SeeTire Inspection
and Rotation on page 6‑71.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. See Engine Oilon
page 6‑17. An Emission Control Service.
When the Change Engine Oil Soon message displays,
service is required for the vehicle as soon as possible,
within the next 1 000 km/600 miles. If driving under the
best conditions, the engine oil life system might not
indicate the need for vehicle service for more than a
year. The engine oil and filter must be changed at least
once a year and the oil life system must be reset. Your
dealer has trained service technicians who will perform
this work and reset the system. If the engine oil life
system is reset accidentally, service the vehicle within
5 000 km/3,000 miles since the last service. Reset the
oil life system whenever the oil is changed. See Engine
Oil Life System on page 6‑20. When the Change Engine Oil Soon message displays,
certain services, checks, and inspections are required.
The services described for Maintenance
Ishould be
performed at every engine oil change. The services
described for Maintenance IIshould be
performed when:
.Maintenance Iwas performed the last time the
engine oil was changed.
.It has been 10 months or more since the Change
Engine Oil Soon message has displayed or since
the last service.
Maintenance I
.Change engine oil and filter. See Engine Oilon
page 6‑17. An Emission Control Service.
.Engine coolant level check. See Engine Coolant
(4.6L Engine)on page 6‑27or Engine Coolant
(3.9L Engine) on page 6‑31.
.Windshield washer fluid level check. See
Windshield Washer Fluid on page 6‑39.
.Tire inflation check. See Inflation - Tire Pressureon page 6‑65.
.Tire wear inspection. See Tire Inspection and
Rotation on page 6‑71.
.Rotate tires. See Tire Inspection and Rotationon
page 6‑71.
7-3

.Fluids visual leak check (or every 12 months,
whichever occurs first). A leak in any system must
be repaired and the fluid level checked.
.Engine air cleaner filter inspection (vehicles driven
in dusty conditions only). SeeEngine Air Cleaner/
Filter on page 6‑21.
.Brake system inspection (or every 12 months,
whichever occurs first).
Maintenance II
.Perform all services described in Maintenance I.
.Steering and suspension inspection. Visual
inspection for damaged, loose, or missing parts or
signs of wear.
.Engine cooling system inspection. Visual
inspection of hoses, pipes, fittings, and clamps
and replacement, if needed.
.Windshield wiper blade inspection for wear,
cracking, or contamination and windshield and

on page 6‑106. Worn
or damaged wiper blade replacement. See
Windshield Wiper Blade Replacement
on
page 6‑55.
.Body hinges and latches, key lock cylinders, and
rear compartment, hood, glove box door, and
console door hinges and latches lubrication. See
Recommended Fluids and Lubricants
on
page 7‑9. More frequent lubrication may be
required when vehicle is exposed to a corrosive
environment. Applying silicone grease on
weatherstrips with a clean cloth makes them last
longer, seal better, and not stick or squeak.
.Restraint system component check. See Checking
the Restraint Systems on page 2‑74.
.Engine air cleaner filter inspection. See Engine Air
Cleaner/Filter on page 6‑21.
.Passenger compartment air filter replacement
