Run ning
in
The treatment given to a new car will have an
impo
rtant
bearing on its subsequent
life,
and
engine speeds during this early period must be limited. The following
instructions should be strictly
adh
ered to.
Dur
ing the first 500 miles (800 km.):
DO
NOT
exceed 45 m.p.h . (72 km .p.h .).
DO
NOT operate at full throttle in any gear.
DO
NOT
allow the engine to l
abou
r in any gear.
Ta
chome
te
r
Fo
r normal roa d work,
and
to
obtain
the most satisfactory service from
your
engine, select the
appro
priate gear to maintain engine speeds of between 2,000
.
and
4,500 r.p.m.
When
maximum acceleration is required upward gear selections should be
made
when the needle reaches the yellow sector (5,500- 6,300 r.p .m.). Prolonged or
excessive use of the highest engine speeds will tend to shorten the life of the
engine. Allowin g the engine to pull hard at low engine speeds must be avoided
as this also has a det rimental effect on the engine.
The beginning of the red sector
(6,300 r.p .m.) indicates the maximum safe speed

Testing
brake
s
The
warning light on the fascia panel will glow when the
brake
pedal is pressed
if an excessive.difference in pressure exists between the
front
and
rear hydraulic
systems as a result of a hydraulic failure or extreme lack of adjustment on the
rear
brake
s.
To test the warning lamp bulb, electrical supply,
and
serviceability of the wiring
to the operating valve, press the test-push on the
bottom
of the
lamp
mounting
plate.
The
lamp will glow if the electrical system is operating satisfactorily.
Release the test-push
and
apply
normal
foot pressure to the brake pedal; the
lamp will remain off if the brakes are functioning satisfactorily. Check the
brake
warning system frequently.
If
the warning
lamp
glows at any time except when the electrical system is being
tested, whether during
normal
driving or when the brakes are being tested as
abo
ve, the cause must be investigated by your Di
stributor
or Dealer at the
earliest possible opportunity.
Vehicle
loading
Due considera
tion
must be given to the overall weight carried when h illy loading
the car. Any loads carried on a
roof
rack or downward
load
from a towing
hitch must also be included in the maximum loading.
Tow
ing The towing weight of 1,344 lb. (610 kg.) is the max imum that is permissible.
When
using
bottom
gear a gradient of up to 1 in 8 can be ascended while towing
a weight
not
exceeding this figure.
It
may be necessary to adjust the maximum
towing weight to comply with local conditions
and
regulations.
The
recommended
downward load of a trailer or
cara
van on the towing hitch is 75 to 100 lb. (34
to 45 kg.),
but
this may be reduced or exceeded at the discretion of the driver.
Any
load
car ried on the
roof
or downward load from a towing hitch must also
be included in the maximum loading
of
the vehicle.
Testing
brakes
The
warmng light on the fascia panel will glow when the
brake
pedal is pressed
if an excessive difference in pressure exists between the
front
and
rear hydraulic
systems as a result of a hydraulic failure or extreme lack of ad
justment
on the
rear
brake
s.
To test the warning lamp bulb, electrical supply,
and
serviceability of the wiring
to the operating valve, press the test-push on the
