Power
Steering
The power steering system
uses
hydraulic
power
to boost manual
the steering forces.
The
rubbing noises heard when the
steering
is al
Tull
lock are normal, and
do not
indicate
a malfunction
in the steering
system.
Bear
in
mind that when the
engine
is
shut
off
(during towing, for
example),
or if
the
power steering
fails,
no steering boost will
be provided and steering
will
require con-
siderably
more effort.
Checking the hydraulic lluid
The
reservoir
is
mounted on
the
right
wheel
well
in the
engine compartment.
The fluid level in
the
transparent
container
should
be
between
the
upper
and
lower
marks.
Top
up
with
hydraulic
fluid
if
neces-
sary. Use only the fluid specified in
the "Fluid
Capacities" section.
