Hydraulic Clutch
It is not necessary to regularly
check clutch fluid unless you
suspect there is a leak in the
system. Adding fluid will not correct
a leak. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
When to Check and What
to Use
The hydraulic clutch fluid reservoir
cap has this symbol on it. See
Engine Compartment Overview on
page 10‑10for reservoir location. Refer to the Maintenance
Schedule for the proper fluid
to use. See
Recommended Fluids
and Lubricants on page 11‑6.
The fluid requires changing every
two years. See Scheduled
Maintenance on page 11‑2.
How to Check and Add Fluid
Visually check the clutch fluid
reservoir to make sure the fluid level
is at the MIN (minimum) line on the
side of the reservoir. The hydraulic
clutch fluid system should be closed
and sealed.
Do not remove the cap to check
the fluid level or to top‐off the fluid
level. Remove the cap only when
necessary to add the proper fluid
until the level reaches the MIN line.
Engine Air Cleaner/Filter
See Engine Compartment Overview
on page 10‑10 for the location of the
engine air cleaner/filter.
Notice: If you spray water into
the engine air cleaner/filter intake
and water enters the engine air
cleaner/filter housing, you could
damage your vehicle's engine.
The repairs would not be covered
by your warranty. Do not spray
water into the engine air cleaner/
filter intake and/or housing.
If cleaning the vehicle with the hood
open, take care not to spray water
directly near the filter opening of
the air cleaner, as shown in the
illustration, as this could damage
the vehicle's engine.

Vehicle Care 10-25
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter
at the scheduled maintenance
intervals and replace them at
the first oil change after each
80 000 km (50,000 mile) interval.
SeeScheduled Maintenance on
page 11‑2 for more information.
If driving in dusty/dirty conditions,
inspect the filter at each engine oil
change. How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter,
remove the filter from the vehicle
and lightly shake the filter to release
loose dust and dirt. If the filter
remains caked with dirt, a new filter
is required.
To inspect or replace the engine air
cleaner/filter:
1. Open the hood. See
Hood on
page 10‑9.

See Maintenance Replacement
Parts on page 11‑8.
9. Reverse Steps 2 through 7 to replace the air cleaner/filter
cover.
{WARNING
Operating the engine with the air
cleaner/filter off can cause you
or others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Notice: If the air cleaner/filter is
off, dirt can easily get into the
engine, which could damage it.
Always have the air cleaner/filter
in place when you are driving.
