Cold Weather-In
cold weather (0° F.
and
colder) the engine must
idle
with the
control lever
in the N position
until
engine and trans-
mission
are warmed
up.
When engine is cold and
running
at fast
idle,
the
car
will tend to
creep when the control
lever
is
moved to
a driving
position. A
slight
application of the foot brake or
hand
brake
will
hold the
car
until
motion
is
desired.
OPERATING IN DR RANGE-DR
range
has
two
driving
posi-
tions,
each
marked by an
arrow.
The control
lever
can
be
moved at
will from one arrow position
to the
other when
traveling
at
a ny
car
speed on dry roads where
traction is
good.
The
left hand
arrow
position
in
DR
range
is provided for all
normal forward
driving;
it reduces
engine speed, provides
better
driving comfort
and improves fuel
economy.
When driving in this
range
at a
car
speed
of
less
than
60
MPH an extra burst of
speed
can
be obtained
for passing by
completely depressing
the
accelerator
pedal. This
will
cause
the transmission to
shift
down to
third
speed.
The transmission will automatically
return to fourth
speed as car
speed increases
or pedal
is
released.
The
right
hand arrow
position
in DR
range
is
provided for
better
acceleration
and is
very
useful
when
driving in
congested
traf-
fic. I
t
is
a
lso
effective when ascending or
descending long
mountain grades.
When
driving in
either
DR
range
at
a car speed
of
less
than 20 MPH an extra burst of speed can
be
obtained by com-
pletely depressing
the accelerator pedal.
This
will cause the
trans-
mission to
shift
down to
second speed.
The
transmission will auto-
matically
return
to third
or fourth
speed,
depending
on the
DR
range
being
used,
as
car speed
increases
or pedal
is
released.
Acceleration in DR Range-The
shift events from first speed to
second, second speed
to
third,
and third
speed
ico
fourth (direct
drive)
will occur at progressively
higher car
speeds
depending
on the amount
the
accelerator pedal
is
depressed.
Caution
Against
Coasting in Neutral-Do
not coast with
the
control
lever
in the N
(neutral)
position. It is unlawful in some
states
and sometimes is harmful
to
the transmission.
