Maintenance
Maint enance269

Some of the most important saf ety
precautions are given here. However,
we cannot warn you of every
conceivable hazard that can arise in
perf orming maintenance. Only you
can decide whether or not you
should perf orm a given task.
Regularly maintaining your vehicle is
the best way to protect your
investment. Proper maintenance is
essential to your saf ety and the
saf ety of your passengers. It will also
reward you with more economical,
trouble-f ree driving, and help reduce
air pollution. This section includes instructions f or
simple maintenance tasks, such as
checking and adding oil. Any service
items not detailed in this section
should be perf ormed by a Honda
technician or other qualif ied
mechanic.
Maintenance Saf ety
Maint enance270
Failure to properly follow
maintenance instructions and
precautions can cause you to
be seriously hurt or killed.
Always follow the procedures
and precautions in this owner’s
manual.
Improperly maintaining this
vehicle or failing to correct a
problem before driving can
cause a crash in which you can
be seriously hurt or killed.
Always follow the inspection
and maintenance
recommendations and
schedules in this owner’s
manual.

Bef ore you begin any maintenance,
make sure your vehicle is parked on
level ground and that the parking
brake is set. Also, be sure the engine
is of f . This will help to eliminate
several potential hazards:Be sure
there is adequate ventilation
whenever you operate the engine.
Let the
engine and exhaust system cool
bef ore touching any parts. Read the instructions before you
begin, and make sure you have the
tools and skills required.
To reduce the possibility of f ire or
explosion, be caref ul when working
around gasoline or batteries. Use a
commercially available degreaser or
parts cleaner, not gasoline, to clean
parts. Keep cigarettes, sparks, and
flames away from the battery and all
f uel-related parts.
Do
not run the engine unless in-
structed to do so. You should wear eye protection and
protective clothing when working
near the battery or when using
compressed air.

The Maintenance Schedule specif ies
how of ten you should have your
vehicle serviced and what things
need attention. It is essential that
you have your vehicle serviced as
scheduled to retain its high level of
saf ety, dependability, and emissions
control perf ormance.Service your vehicle according to the
time and mileage periods on one of
the Maintenance Schedules on the
f ollowing pages. Select the schedule
f or ‘‘Severe Conditions’’ if most of
your driving is done under one or
more of the conditions listed on that
page. Otherwise, f ollow the schedule
f or ‘‘Normal Conditions.’’
The services and time or distance
intervals shown in the maintenance
schedule assume you will use your
vehicle as normal transportation f or
passengers and their possessions.
You should also f ollow these
recommendations:
Avoid exceeding your vehicle’s
load limit. This puts excess stress
on the engine, brakes, and many
other parts of your vehicle. The
load limit is shown on the tire
inf ormation label on the driver’s
doorjamb. Operate your vehicle on
reasonable roads within the legal
speed limit.
Drive your vehicle regularly over a
distance of several miles
(kilometers).
Always use unleaded gasoline with
theproperoctanerating(seepage
).

U.S. Vehicles:
Your authorized Honda dealer
knows your vehicle best and can
provide competent, ef f icient service.
However, service at a dealer is not
mandatory to keep your warranties
in effect. Maintenance may be done
by any qualif ied service f acility or
person who is skilled in this type of
automotive service. Keep all the
receipts as proof of completion, and
have the person who does the work
f ill out the Maintenance Record.
Check your warranty booklet f or
more inf ormation. We recommend the use of genuine
Honda parts and f luids whenever you
have maintenance done. These are
manuf actured to the same high-
quality standards as the original
components, so you can be conf ident
of their perf ormance and durability.
According to state and federal
regulations, f ailure to perf orm
maintenance on the items marked
with will not void your emissions
warranties. However, Honda
recommends that all maintenance
services be perf ormed at the
recommended time or mileage
period to ensure long-term reliability.

Maintenance, replacement or
