Cold Weather-In cold weather
(O°F.
and
colder) the engine must idle with the con-
trollever in P (park) or N
(neutral)
position
until engine and transmission are warmed
up. This can more safely be done in the P
(park) position as the transmission will then
keep the car from rolling on a grade or
incline. When engine is cold and running at fast idle, the car will
tend to creep wben the control lever is moved to a driving position.
A light application of the foot brake or parking brake will hold the car
until motion is desired.
OPERATING
IN DR
RANGE-DR range has two driving positions,
each marked by an
arrow.
The control lever can be moved at will
frdm one arrow position to the other when traveling at any 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 bette~
driving comfort and improves fuel economy.
When driving in this range at a car
speed
of
less than 65 mph extra performance can
be obtained by depressing the accelerator pedaL This will cause the
transmission to
shift
down into third
speed.
The car speed determines
the amount the accelerator pedal must be depressed to cause this
shift.
At a speed of about 35 mph or less the accelerator pedal need
only
be partially depressed to cause the shift
and
at speeds <.>f 35
mph to 65 mph it is necessary to completely depress the pedal. The
transmission will autofuatically return to fourth speed as car speed
increases or the accelerator pedal is released.
The right hand arrow position in DR range
is provided for better acceleration and is
very useful when driving in congested
traffic.
It is also effective when ascending
or descending long mountain grades. When
driving in either DR range at a car
speed
of less than 24 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 the car
speed
increases
or
pedal is released.
