Hydraulic Clutch
The hydraulic clutch linkage in your 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 322 for
reservoir location.
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
Refer to the Maintenance Schedule to determine
how often you should check the fluid level in
your clutch master cylinder reservoir and for the
proper fluid. See Recommended Fluids and
Lubricants on page 440.
