ACCELERATOR PEDAL
The accelerator pedal is the pedal on the right, with the word GO molded into it (Figure 9). The operation of the accelerator
pedal differs from that of an automobile. When the key switch is the ON position, and the Forward/Reverse switch is in either
the FORWARD or REVERSE position, pressing the accelerator pedal will automatically release the park brake and start the
vehicle moving in the direction selected (forward or reverse). As the accelerator pedal is pressed, speed will increase until
full speed is reached. When the accelerator is released, power will be cut off and the motor will stop running.
Electric vehicles use a special electrical system, which employs motor braking in some modes of operation. In those
modes, the vehicle operates as follows:
• Walk Away Braking: This feature prevents the vehicle from rolling away uncontrolled should the driver park on a slope
and leave the vehicle without locking the park brake. The vehicle will roll at about 1 mph (1.6 km/h). If the walk away
braking function remains engaged for two seconds or more, a warning buzzer will sound to alert the driver that motor
braking has been activated. See following WARNING.
WARNING
• Walk away braking will not limit vehicle speed to 1 mph (1.6 km/h) on very steep grades.
Do not operate vehicle on slopes exceeding 20% grades.
Excel System Vehicles
• Motor Braking:This feature helps to control vehicle downhill speed. When traveling downhill, motor braking engages to
maintain speeds proportional to the accelerator pedal position. For example, when the accelerator is fully pressed, motor
braking holds the vehicle at the programmed top speed. When the accelerator pedal is fully released, motor braking slows the
vehicle to a complete stop or allows the vehicle to coast freely, depending upon the selected controller setting. This feature is
selectable. Contact your dealer/distributor to inquire about this feature.
IQ System Vehicles
• Pedal Up Motor Braking: When vehicle speed is above 11 mph (17.7 km/h), releasing the accelerator pedal will activate
motor braking, which slows the vehicle speed. Once vehicle speed slows to below approximately 11 mph (17.7 km/h), with the
accelerator pedal still released, motor braking will be deactivated and the vehicle will coast freely. This feature is selectable.
Contact your dealer/distributor to inquire about this selectable feature.
• Pedal Down Motor Braking: This feature helps to control vehicle downhill speed. Motor braking is activated when the
vehicle reaches the programmed top speed and holds the vehicle at that speed. Motor braking is automatically disengaged
when vehicle speed slows below the programmed top speed.
