Maintenance Schedule for Severe Conditions (listed by distance/time)

µµKeeping the tires properly inf lated
provides the best combination of
handling, tread lif e, and riding
comf ort. Underinf lated tires wear
unevenly, adversely affect handling
and f uel economy, and are more
likely to f ail f rom being overheated.
Overinf lated tires can make your
vehicleridemoreharshly,aremore
prone to damage from road hazards,
and wear unevenly.
We recommend that you visually
check your tires every day. If you
think a tire might be low, check it
immediately with a tire gauge.
To saf ely operate your vehicle, your
tires must be the proper type and
size, in good condition with adequate
tread, and correctly inf lated. The
f ollowing pages give more detailed
informationonhowandwhento
check air pressure, how to inspect
your tires f or damage and wear, and
what to do when your tires need to
be replaced.
The timing belt should normally be
replaced at the intervals shown in
the maintenance schedule.
Replace the belt at 60,000 miles (U.S.)
or 100,000 km (Canada) if you regu-
larly drive your vehicle in one or
more of these conditions:
In very high temperatures
(over 110°F, 43°C).
In very low temperatures
(under 20°F, 29°C).
Frequently tow a trailer. Inf lation

Maint enance332
Using tires that are excessively
worn or improperly inflated can
cause a crash in which you can
be seriously hurt or killed.
Follow all instructions in this
owner’s manual regarding tire
inflation and maintenance.
