removing the
drain
plug
on
the rear face oí the oil

a very high temperature and
injury may be caused if
allowed to contact
the hands.
ReÍilling

best carried out by
first
pouring
in
3{
pints
(2
litres)
of
fluid, then start the engine and allow
it
to
idle while sufficient
Íluid
is added to bring
it
up
to the
MAXI mark on the diostick.
The manufacturers advise against any
adjustments of
the transmission or
its
controls and
in the event of
a
breakdown the car should be taken to an accredited
agent
for
attention or a new unit
Íitted. For those owners
who
