Heating and Air Conditioning
Heating and Air Conditioning switches
have the same functions for the battery
electric truck as the diesel powertrain.
Since this truck is powered by a battery
electric powertrain, it does not generate
enough waste heat to power the cabin
heater. Instead, the propulsion battery
pack’s power is used to heat the cab. It
will take 1-2 minutes for the truck to
start generating warmer air. Using the
cab heater will reduce the truck’s range.
Dash Switches
Retarder Switches
Regenerative braking is used to imitate
defueled engine drag and engine
retarder levels with retarder
functionality allowed at lower truck
speeds. Two switches exist for
controlling the retarder levels.
The Retarder ON/OFF switch turns off all
regenerative braking. When the retarder
switch is in the OFF position and 0%
accelerator pedal demand occurs, the
truck will be coasting with no braking
effort from the propulsion motors.
Below are the retarder switch level
settings.
Level Retarder Behavior
Low
Imitate defueled engine drag
Med Medium Engine Braking Level
High High Engine Braking Level
Fan Switch
Since the truck uses an electric
powertrain fan that automatically runs,
the fan override switch is no longer an
option and will not be included.
WARNING!
Turn the Retarder ON/OFF switch to
the OFF position when low traction
road conditions exist (e.g. ice, rain,
gravel). Use the foundation brakes
instead for optimal braking control.
Failure to heed this warning could
result in injury, death, or equipment
and property damage.
NOTE
Turn the retarder switch to the ON
position to enable regen braking and
maximize the truck range.
