while the vehicle is in motion or running the
engine while standing with brake applied.
DO NOT COAST IN NEUTRAL.
DRIVE RANGE "D"- The driving range for
city and highway driving. This position per-
mits the transmission to operate through its
complete range of gear ratios and to select
automatically the proper ratio for road and
load conditions.
SUPER RANGE "S"-Used when super per-
formance is needed for increased acceleration
in traffic, hill climbing, or "Engine Braking"
down-hill. The selector lever may be moved
from "D" to "S" and vice versa, under most
operating conditions. "SUPER" should not
be used at speeds above 75 MPH.
LOW "L"-Available for heavy pulling
through mud or sand and for engine braking
when descending steep hills. The selector lever
may be moved to "L" at any speed but the
transmission will only shift automatically
into Low range when the vehicle speed is
under approximately 40 MPH. The trans-
mission will not upshift from Low range as
long as the selector lever is in the "L" position .
CAUTION
Before descending a
steep or long
grade, down a ma+ontain or hrilside,
reduce speed and shift
into a
lower
gear . Use the lower gear ranges xo con-
trol vehicle
speed,
Avoid prolonged or
frequent
application
of
the
brakes
which could cause overheating and thus
reduce brake effectiveness . Use caution
14
when shifting into lower range or lower
gear on slippery surfaces with vehicle
moving-abrupt engine braking action
could cause the front wheels to skid,
possibly leading to loss of vehicle con-
trol.

acceleration is desired to pass moving ve-
hicles or to climb steep grades at speeds
between approximately 35 and 65 MPH, the
transmission can be downshifted by depress-
ing the accelerator pedal completely to the
floor . It is also possible to obtain a forced
downshift in "DRIVE" range at speeds under
3 5 MPH by depressing the accelerator pedal
part way down.
