DIRECTIONAL
SELECTOR FUNCTIONS
The Extended Range Electric Truck is
powered by direct drive electric motor.
A transmission is not required. The gear
selector on the column is actually a
directional and park selection device. It
functions as follows:
Reverse
The R or reverse
selection will cause
the vehicle to back up.
Make sure the vehicle
is completely stopped
before making the next
selection.
Neutral
The N or neutral selection
will remove power fl ow
to the electric drive. The
vehicle may roll if left in
this position.
Drive
The D or drive selection
is the normal operating
position. This will allow the
truck to go forward. You
will not feel gear change as
speed increases because
the truck is direct drive.
P R N D M
The P or park position uses an
electrically operated device that locks
up the drivetrain to prevent movement
while parked. This takes a small amount
of time to engage and disengage. It
should always be used in conjunction
with the parking brake. Park will not
engage if the truck is moving. Care
should be taken to allow engagement
of park before leaving the truck. The
12 volt battery is needed to engage
park. The ignition should be left in the
on position and park engaged before
turning the vehicle off and removing
the key. If park (P) is not engaged within
3 seconds of turning, the key to the off
position the park pawl will not engage.
Always use the parking brake in
conjunction with park.
Position M
This position is a manually
selected power assist
function. The APU is
enabled and provides
additional power during
low battery temperature /
state of charge, large hill
climb, or other conditions
where the power from
the high voltage battery is
insuffi
cient to operate the
vehicle at the requested
level. Battery level at the
time of engaging M will be
maintained.
Drive (D ) is the preferred
position for normal operation.
