Controls and Indicators
• Batteries have discharged to less than 25% of rated capacity.
If the warning light illuminates when the vehicle is operating, there will be enough power remaining to drive the vehicle
for approximately 30 minutes. However, the vehicle should be charged at the first opportunity. If the warning light
illuminates and the vehicle is unable to operate for 30 minutes, have your Husqvarna distributor/dealer check the
vehicle for a possible battery or electrical system problem.
When the batteries receive an incomplete charge because 1) the DC power cord is disconnected, 2) AC power
to the charger is interrupted, 3) automatic charger shut-off occurs after 16 hours of operation, or 4) the charger
malfunctions, the warning light will indicate as follows:
• The warning light will not illuminate if the charge is 90% or more complete. The onboard computer will retain in
memory the amount of charge needed to fully replenish the batteries and will complete the charge during the
next charge cycle.
• When the charger is unplugged, the warning light will illuminate and remain illuminated for 10 seconds if the charge
is less than 90% complete but the vehicle has enough power for approximately 30 minutes of operation. This will
alert the operator that the vehicle may be used, but that it must be charged to completion as soon as possible.
• The warning light will repeatedly illuminate for 10 seconds, with 4 second intervals if the charger times out at 16
hours and the batteries are not sufficiently charged. See the battery charger owner's manual. This indicates an
abnormal charge cycle. The charger and batteries should be checked by your Husqvarna distributor/dealer.
• The warning light will repeatedly illuminate for 10 seconds, with 4 second intervals during a charge cycle (DC plug is
still connected) if AC power to the charger is interrupted. The light will go out when AC power is restored.
LED Light: In addition to the warning light, there is an infrared LED in the dash light assembly, which transmits an
infrared signal from the onboard computer (OBC). This signal is received by the optional Communication Display
Module (Husqvarna 603 00 18-63), which provides information on the condition of the vehicle and batteries.
TOW/RUN SWITCH
Electric Vehicles Only
WARNING
• Place Tow/Run switch in the TOW position before disconnecting or connecting the batteries. Failure to
heed this warning could result in a battery explosion or severe personal injury.
• When the Tow/Run switch is in the TOW position, all motor braking functions, including walk-away
braking, are disabled.
Electric vehicles are equipped with a Tow/Run switch, located under the seat just above the Forward/Reverse switch
(Figure 13). The switch must be in the RUN position in order to operate the vehicle. When the switch is in the TOW
position, power to the vehicle electrical components is turned off and the vehicle will not operate. See following NOTE.
NOTE: After placing the Tow/Run switch in the TOW position, allow 10 seconds to elapse before switching back to
the RUN position.
After placing the Tow/Run switch in the RUN position, allow 10 seconds to elapse before operating the vehicle.
The Tow/Run switch should be placed in the TOW position under the following conditions:
• Before Towing the Vehicle: Place the Tow/Run switch in the TOW position to disable all motor braking functions,
thus preventing possible damage that could occur to the vehicle or electrical components if the vehicle is towed
while the walk-away braking function is operating.
• Before Disconnecting or Connecting Battery Cables: Place the Tow/Run switch in the TOW position to turn
off power to the vehicle electrical system, thus preventing severe arcing and possible battery explosion as the
battery cables are disconnected.
• For Long Term Storage: Place the Tow/Run switch in the TOW position to turn off power to the vehicle electrical
system, thus preventing vehicle electrical components from discharging the batteries.
