Maintenance
Requirements
Notice:Maintenance intervals,
checks, inspections, replacement
parts, and recommended uids
and lubricants as prescribed
in this manual are necessary to
keep your vehicle in good
working condition. Any damage
caused by failure to follow
scheduled maintenance might not
be covered by warranty.
Your Vehicle and the
Environment
Proper vehicle maintenance not only
helps to keep your vehicle in good
working condition, but also helps the
environment. All recommended
maintenance is important. Improper
vehicle maintenance can even affect
the quality of the air we breathe.
Improper uid levels or the wrong tire
ination can increase the level of
emissions from your vehicle. To help
protect our environment, and to keepyour vehicle in good condition, be
sure to maintain your vehicle
properly.
Using the Maintenance
Schedule
We want to help you keep your
vehicle in good working condition.
But we do not know exactly how you
will drive it. You might drive very
short distances only a few times a
week. Or you might drive long
distances all the time in very hot,
dusty weather. You might use your
vehicle in making deliveries. Or
you might drive it to work, to
do errands, or in many other ways.
Because of all the different ways
people use their vehicles,
maintenance needs vary. You might
need more frequent checks and
replacements. So please read the
following and note how you
drive. If you have any questions on
how to keep your vehicle in good
condition, see your dealer/retailer.This schedule is for vehicles that:
carry passengers and cargo
within recommended limits.
You will nd these limits on the
Tire and Loading Information
label. SeeLoading the Vehicle on
page 8-28.
are driven on reasonable road
surfaces within legal driving limits.
use the recommended fuel. See
Gasoline Octane on page 8-33.
The services inScheduled
Maintenance on page 11-4should
be performed when indicated.
SeeAdditional Required Services
on page 11-6andMaintenance
Footnotes on page 11-7for further

{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
dealer/retailer to have a
qualied technician do the
work. SeeDoing Your Own
Service Work on page 9-4.Some maintenance services can be
complex. So, unless you are
technically qualied and have the
necessary equipment, you
should have your dealer/retailer do
these jobs.
When you go to your dealer/retailer
for your service needs, you will
know that trained and supported
service technicians will perform the
work using genuine parts.
If you want to purchase service
information, seeService
Publications Ordering Information on
page 12-15.
Owner Checks and Services on
page 11-9tells 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 11-12
andMaintenance Replacement
Parts on page 11-13. When
your vehicle is serviced, make sure
these are used. All parts should
be replaced and all necessary
repairs done before you or anyone

Scheduled Maintenance
When the Service Engine Oil
message 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. SeeEngine Oil Life
System on page 9-10for information
on the Engine Oil Life System
and resetting the system.
When the Service Engine Oil
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
MaintenanceIIthereafter. However,
in some cases, MaintenanceII
may be required more often.MaintenanceI— Use
MaintenanceIif the Service Engine
Oil message comes on within
10 months since the vehicle was
purchased or MaintenanceII
was performed.
MaintenanceII— Use
MaintenanceIIif the previous
service performed was
MaintenanceI. Always use
MaintenanceIIwhenever the
Service Engine Oil message comes
on 10 months or more since the
last service or if the message
has not come on at all for one year.

hoses for proper hook-up, binding,
leaks, cracks, chafing, etc. Inspect
disc brake pads for wear and rotors
for surface condition. Inspect drum
brake linings/shoes for wear or
cracks. Inspect other brake parts,
including drums, wheel cylinders,
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)

cracking, or contamination.
Clean the windshield and wiper

reminder light and safety belt
assemblies are working properly.
Look for any other loose or
damaged safety belt system parts. If

door hinges and latches, hood
hinges and latches and trunk lid

seal better, and not stick or squeak.
(g)Visually inspect belt for fraying,
excessive cracks, or obvious
damage. Replace belt if necessary.(h)Change automatic transmission
fluid and filter if the vehicle is
mainly driven under one or more of
these conditions:

In hilly or mountainous terrain.
When doing frequent trailer
towing.
Uses such as found in taxi,
police, or delivery service.

could indicate a problem. Have
the system inspected and repaired
and the fluid level checked. Add
fluid if needed.
(k)If you drive regularly under dusty
conditions, inspect the filter at
each engine oil change.
(l)If you drive regularly under dusty
conditions, the filter may require
replacement more often.
(m)Drain, flush, and refill brake
hydraulic system at a regular service
interval (IorII) every two years.
