Speed Control
• To maximize your vehicle’s driving range only use the speed you need if using the OTF.
• Use the speed knob to control your maximum cruising speed, turn the speed down to the
minimum practical speed necessary for the application. The controller signicantly increases
the operating efciency of the motor as the maximum speed adjustment is reduced.
• Minimize acceleration - hard acceleration demands high in-rush currents from the battery
pack. This increases wear and tear on both the motor and the mechanical systems.
Hill Descent
• Use regenerative braking for hill descent - it puts energy back into the battery and it
increases the life of your brakes. Regenerative Braking can be applied gradually and can
reduce the likelihood of losing traction when going down a hill.
Low Battery Warning
• When the battery discharged warning (1-5 ash) is given by the OTF (if present), the
controller will reduce the amount of power it supplies to the motor to protect the motor.
• Cycling the key will reset full controller power for 1 minute but doing so repeatedly will
adversely affect the life of your motor. Recharge the batteries as soon as possible.
Heavy Duty Usage
• If you notice that your cables or motor are becoming too hot to touch, then your application
is probably too demanding and we recommend that you upgrade the motor to a speed/torque
system, and upgrade the cables to at least 4 AWG.
Warnings
• Always monitor the motor & battery wiring temperatures after changing the programmer
settings (if OTF is present) – particularly when going to higher speeds
• If your battery pack is full, the amount of regenerative braking may be reduced since the
controller has nowhere to put the excess energy.

• Modifying motor controller parameters may change vehicle acceleration, braking
and top speed behavior. Please verify vehicle performance before the use and obey
federal, county and municipality bylaws and regulations.
• Product use is for golf car and Low Speed Vehicle (LSV) market application and
may operate at speeds Up to 25 MPH. Factory settings on controller have been set
using: 18 inch diameter tires, non-performance motor & up to 25 MPH limit with
vehicle speed sensor installed.
• Operators/Users of Navitas golf car and LSV equipped products must follow
published golf car & LSV federal, state, county & municipal bylaws & regulations
issued for your “use area”. For operation/use beyond golf car & LSV regulations/
guidelines, full liability Is assumed by operators/users.
• Do not leave children or pets unattended in or near the vehicle. Always look behind
you before and while backing up.
• Reduce speed when towing and allow more room for stopping and turning.
• Drive with wheels straight when going up and down hills. Slow down and use
brakes when going down hills.
• Never drive on hills with a slope greater than 15 degrees.
• Do not drive through fast owing water or water above the oor of the vehicle.
• If you must cross shallow water, make sure to stop and inspect the area for sudden
drop-offs, large rocks or slippery surfaces. Always proceed with caution or choose a
safer route.
• When towing this vehicle make sure the key is turned off, the Run/Tow switch is in
Tow, and batteries main power is disconnected.
FAILURE to follow the WARNINGS below can damage
the Vehicle and/or cause SERIOUS INJURY OR DEATH!
DANGER
MAKE SURE TO READ and UNDERSTAND the OWNER’S INSTALLATION and SERVICE MANUAL
and ALL WARNING LABELS with this Controller.
Make sure to also Read, Understand, and follow the Vehicle’s OWNER’S MANUAL and
ALL INSTRUCTIONS and WARNING LABELS.
• Always proceed with caution. Keep speed low and do not drive faster than conditions
permit. Terrain, conditions, and the operator’s skill will determine a safe speed. Avoid
sharp turns and do not accelerate quickly when turning as this can cause the vehicle
to slide sideways or skid out of control. Abrupt manoeuvres or aggressive driving can
cause a rollover even on at open areas.
• This controller will increase torque, but DOES NOT increase the GVWR (Gross Vehicle
Weight Rating), cargo capacity, or towing capacity of the vehicle. Always follow the
vehicle towing and loading specications.
SAFETY WARNINGS

INSTALLATION/ SERVICE MANUAL

• Never exceed the towing capacity rating as specied by the vehicle manufacturer.
• Never re-wire, by-pass or change the wires, switches, or controller. Contact your
dealer if vehicle is not operating correctly.
• Keep the controller and the area around it clean and free of debris. Keep electrical
components dry and DO NOT wash with direct stream or power washer
• Driver must be a minimum of 16 years of age with a current driver’s license, or be
accompanied by a parent or legal guardian when operating the car.
• Do not drive vehicles while inuenced by alcohol, medications & drugs as this may/
will impair your safe driving use.
• User to verify that golf car & LSV vehicle mechanical brakes are fully functional
prior to continued operation of vehicle.
• Vehicle & all parts must be serviced by qualied service personnel. For an
authorized service location see your local dealer or visit our web site at www.
