Battery Status Indicator 
The battery status indicator (BSI) is shown on the right side of the dash display main screen. This gauge functions like a fuel gauge in an automobile. At the top of the gauge, it shows the percentage remaining in the battery.  

The BSI is not an absolute gauge of power remaining in the battery. The amount of available power is relative to the amount of power required. As the power requirements are increased, such as driving up a hill, the relative available power in the battery is decreased. The motor speed control system estimates the battery power remaining by monitoring the current driving conditions.  

There are 10 bars in the bar graph display, each bar representing 10 percent of battery power.  

At 10 percent estimated battery power remaining (one bar showing), a warning message will pop up at the bottom of the display to inform the driver of the low battery condition. It is important to drive to a charging station as soon as possible. If the estimated battery power remaining drops below empty, the control system will reduce the power to the motor in order to conserve energy. To avoid damage to the battery, the vehicle should be immediately taken to a charging station.  

Note: The BSI will only reset to full after a full charging cycle has completed. In addition, the BSI will not reset to full unless the battery is discharged below 75 percent before starting the charge cycle.  

While coasting, the batteries are charged through a process called regenerative braking (regen). It is possible that the BSI could reset to full while in the regen braking mode. Details regarding the regen braking mode can be found in the Vehicle Operation section of the Vehicle Operator and Service Manual.

6. Strobe Light Switch: The strobe light switch is optional. If equipped with a strobe light, push the top of the switch to turn the light ON. Push the bottom of the switch to turn the light OFF. 

7. High Beam Indicator Light: This light illuminates when the headlight high beams are activated. 

8. Headlights: This is a three-position rocker switch.  

All lights are OFF when the switch is in the lowest position (push on bottom of actuator).  

Only the parking lights are ON when the switch is in the second position (push top of actuator one click from OFF).  

All lights are ON when the switch is in the third position (push top of actuator two clicks from OFF). 

Caution: Unless in an emergency, do not activate the emergency stop switch while the vehicle is in motion. This vehicle is equipped with an automatic electric parking brake. Activating the emergency stop switch will immediately apply the brake and abruptly stop the vehicle. This may result in injury to the occupants and/or upsetting the load being carried or towed. 

9. Windshield Wiper: The windshield wiper is optional. The wiper has a two-speed wiper motor. The wiper is OFF when the switch is in the lowest position (push on bottom of actuator).  

  • Normal speed is when the switch is in the second position (push top of actuator one click from OFF).  
  • Fast speed is when the switch is in the third position (push top of actuator two clicks from OFF). 

10. High Beams (Headlight): A push-button latching switch is located on the end of the directional switch lever. Depress and release to turn the high beams ON or OFF. 

11. 4-Way Flashers: The actuator lever for the 4-way flasher is located behind the directional switch lever. Pull the actuator out to turn the 4-way flashers ON.  

To turn the 4-way flashers OFF, move the directional switch lever in either direction. 

12. Directional Signal Switch: Use the directional switch lever to indicate a left or right turn. PUSH the lever away (clockwise) to signal a right turn. PULL the lever closer (counterclockwise) to signal a left turn.  

The directional switch does not automatically reset. Move the lever to the center OFF position after completing a turn. 


Shift Lever: The shift lever has 4-positions.

  • High (H): Move the shift lever to the right and up to the second notch in the index plate. High will allow the vehicle to obtain its maximum speed but will also reduce the running time due to increased demand from the battery.  
  • Low (L): Move the shift lever to the right and up to the first notch in the index plate. Low should be used while pulling loads greater than half of the vehicle capacity or pulling any load up or down a grade.  
  • Off: The lever is shown in the OFF position in the illustration.  
  • Reverse: From the OFF position, move the shift lever to the right and then back. 

Warning: Do not dismount the operator’s seat while the vehicle is in motion. Getting off the seat will activate the Operator Presence circuit, rapidly slowing the vehicle and applying the park brake. The abrupt slowing of the vehicle may result in severe bodily injury. 

The operator presence switch is only one part of the vehicle safety system. It should not be relied upon as the only safety feature used to disable or disengage this vehicle. Doing so could result in unexpected movement of the vehicle causing severe bodily injury and/ or property damage. 

Operator Presence: A switch located under the driver’s seat disables the power to the vehicle when the driver leaves the seat. The driver must be seated for the vehicle to operate. Whenever the driver leaves the vehicle, the driver should turn the key switch OFF and place the shift lever in the center OFF position.  

Foot Brake: This vehicle is equipped with a foot brake interlock. The vehicle control system will not run if the foot brake is applied.  

Parking Brake: This vehicle is equipped with a parking brake interlock. The vehicle control system will not run if the parking brake is applied.  

Rear Charger Connector: A switch located on the charger connector disables power to the vehicle whenever a charger is connected. 

Parking Brake

1. Throttle Pedal: The throttle pedal is located to the right of the brake pedal. It controls the speed of the vehicle and operates like the throttle pedal in an automobile. Press the pedal to increase speed and release the pedal to decrease speed. 

2. Brake Pedal: The foot brake pedal is located to the left of the throttle pedal and is for operation with the right foot only. It works like the brake in an automobile. Applying pressure to the brake pedal slows the vehicle according to the amount of pressure applied. Relieving pressure from the pedal releases the braking action. 

3. Steering: The steering wheel and steering system are like an automobile. To turn right, turn the steering wheel clockwise. To turn left, turn the steering wheel counterclockwise. 

Tilt Steering 
Turn the tilt column locking knob counterclockwise, move the steering column up or down as needed, and tighten the knob to lock the column in place. Be sure the knob it tight enough so that the column cannot move during operation of the vehicle.
