opening
of
the
carburettor butterfly
valve
(s)
, which
represents 50% of
th

stroke,
shiftinq from
1st
ratio
to
2nd
ratio
takes
place at a speed of 22
MPH
or 35.4
kw./h
(speeds
given
as
a
guide):
-
shifting from 2nd ratio
to
3rd
ratio
takes
place
at
a
speed
of
38,5

shi
fting
down
from
3rd

Starting
The engi
ne
can
be started only
w
hen
the selector

Vehicles fitted
with the automatic
transmission cannot
be started
by
pushing or towing.
13)
Mountain
driving
For
mountain driving, when the vehicle
is
heavily
loaded
or towing
a
caravan,
t
he
driver
should
select
position
2
(second
ratio)
or
position 1 (1st
low r atio ), when the gradients require
driving with
F4ti
3
the accelerator
pedal
fully down for
1
km or
~ore,
This
precautionary
measure
reduces
gear box and
converter
overheating, which could otherwise result
from
such conditions,
1~)
Towing
the vehicle
If gear
box has
broken
down:
Lift
rear
of vehicle
for touring,
or
remove
propeller
shaft.
If
gear box operates normally
The
vehicle may be
towed,
with
the selector
lever
in position
N (neutral),
wi
t11 the rear
wheels
In
.
contact
with the road,
at a
speed not exceeding 45
km/h, and over a
distance
of
no more than
100
km,
If the vehicle
is
to
be towed
over a greater
distance,
operators
are advised
to lift the rear of
the vehicle,
or to remove the propeller shaft.
As the transmission
is only
lubricated when the
engine Is running, It Is good practice always to
tow a
broken-
down vehf
c
1 e with the rear end 11 fted
off the road, or with the propeller shaft removed,

Maintenance
151)
Lubrication
The
gear
box oil
and t he
fil
ter are 1eant to
provide satisfactory lubrication and
protec
ti
on
fo
r
the
autom
atic
transmission, and
It Is not
advisable
to change the oil on vehicles used
under
normal conditions.
Periodical oil changes
and
filter replacements,
therefore, are
not necessary,
except
when
the
vehic
le
is
used
under severe
conditions.
If, for some
reason, t
he
oil
Initially
used 111ust
be replaced, this
operation must be carried
out
every 3 years,
or
everv
40,
000
km,
whm
the
vehicl
e
Is used
normally.
152)
Checking
the
oil
level
Check oil
level
every
6 mon
ths, with engine
and
gear
box at
normal operating temperature.
