4. If the fluid level is good, install
the plug and be sure it is fully
seated. If the fluid level is low,
add more fluid as described in
the next steps.
How to Add Fluid
Refer to the Maintenance Schedule
to determine what kind of fluid to
use. See Recommended Fluids and
Lubricants on page 11‑8.
1. Remove the filler plug.
2. Add fluid at the filler plug hole.
Add only enough fluid to bring
the fluid level up to the bottom of
the filler plug hole.
3. Install the filler plug. Be sure the
plug is fully seated.
Hydraulic Clutch
The hydraulic clutch linkage in the
vehicle is self-adjusting. The clutch
master cylinder reservoir is filled
with hydraulic clutch fluid.
The hydraulic clutch fluid reservoir
cap has this symbol on it. See
Engine Compartment Overview on
page 10‑6 for reservoir location.
It is not necessary to regularly
check clutch fluid unless a leak in
the system is suspected. 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
Refer to the Maintenance Schedule
to determine how often to check
the fluid level in the clutch master
cylinder reservoir and for the proper
fluid. See Recommended Fluids and
Lubricants on page 11‑8.
How to Check and Add Fluid
The proper fluid should be added if
the level does not reach the bottom
of the diaphragm when it is in place
in the reservoir. See the instructions
on the reservoir cap.
