1.3 Configuration Options
Options identified by “(if equipped)” indicate an optional configu-
ration is available for different models of this vehicle. Please refer
to your actual vehicle to determine if it is configured with these
options.
1.4 Electrical Equipment
This vehicle has two types of electrical components: low voltage
and high voltage. The low voltage system is similar to traditional
motor vehicle systems and includes lighting and instrumentation.
The primary purpose of the high voltage system is to provide
power for moving the vehicle. The high voltage system is also
used to charge the 12 volt (12V) system. The vehicle will not move
if the 12V system is depleted.
1.4.1 Low Voltage Equipment
The rated working voltage of low voltage electrical equipment is
12 volts. The low voltage system includes the instrument panel,
audio-visual system, lights, speakers, fans, and combination
switches.
1.4.2 High Voltage Equipment
High voltage electrical equipment includes the drive motor, motor
control unit, high voltage battery, air conditioner compressor, and
heater. High voltage cables and connectors are bright orange in
color.
DANGER
High voltage components, usually identifiable by attached
orange cables, present an electrical shock hazard. To avoid
injury, do not touch high voltage components, including the
high voltage wiring harness and connectors.
1.4.3 Maximizing High Voltage Battery Life
Maintaining the State of Charge (SOC) between 20% and 90% will
help improve the longevity of the high voltage battery. Charge the
high voltage battery pack immediately if the SOC is below 20%.
When charging, set the maximum state of charge at 90%.
When not in use, the vehicle should be stored in temperatures
between 32°F (0°C) and 113°F (45°C). If the vehicle will be parked
for an extended period (e.g., 30 days or more), set the maximum
state of charge at 50%.
NOTICE
If left unplugged, the vehicles will use energy from the high
voltage battery to recharge the 12V battery when needed.

2.1 Before Starting the Vehicle
1. Walk around the outside of the vehicle. Make sure the area
around the vehicle is clear of people and obstructions.
Ensure that the air intake areas of the radiator are free of
debris.
2. Take five minutes to inspect the vehicle’s tire pressure and
overall condition prior to driving. Maintain proper tire pres-
sure in all four tires as indicated on the decal affixed in the
driver’s door frame. Keep a tire pressure gauge in the vehicle
for this purpose. Low tire pressure causes premature wear to
the tires and other vehicle components and diminishes vehi-
cle performance and efficiency. Once your exterior inspec-
tion is satisfactory, you may get in the vehicle.
3. Ensure the parking brake is on.
4. Adjust the seat and mirrors.
5. Fasten the seat belt.
6. Turn off unnecessary accessories.
7. Ensure the gear selector dial is in Neutral (N).
8. Turn the ignition switch to ON, but do not start the vehicle
yet.
9. For a brief moment, you should see all the indicator lights on
the instrument panel. Most of these lights will turn off. A few
indicator lights will remain on until you start the vehicle.
2.2 Starting the Vehicle
1. Turn the ignition key to the START position to start the vehi-
cle. The READY indicator turns on when the vehicle is run-
ning. At this point, all other indicator lights should be off.

2. With your foot on the brake pedal, release the parking brake
by lifting up and pressing the button on the end of the lever.
Then push the lever downward to its home position.
3. If the vehicle does not start as it should, turn the key switch
to LOCK. Set the gear selector dial to Neutral (N), place your
foot on the brake pedal, and then try starting the vehicle
again.
4. Select desired gear on the gear selector dial: Drive (D), Econ-
omy (E), or Reverse (R).
5. Remove your foot from the brake pedal and use the acceler-
ator to reach the desired speed.
2.3 Vehicle Operation
2.3.1 Uphill Start
If you are starting the vehicle on an upward incline, leave the park-
ing brake engaged prior to starting the vehicle. Once the vehicle is
started, select the correct gear, and slowly release the parking
brake while using the accelerator pedal to reach the desired
speed.
The motor will produce enough power to handle the incline.
2.3.2 Regenerative Mode
This vehicle features a regenerative mode, or ‘regen’, to extend
the driving range. Regen relies on the motor as a generator to con-
vert kinetic energy from an object in motion to electrical energy
that recharges the high voltage battery.
When the operator presses the brake pedal, regen assists the
brakes by employing the motor to act as a generator. The generat-
ing process creates resistance against the rotating wheels which,
in turn, helps slow the vehicle. As the vehicle slows, electrical
energy is used to replenish the battery.
By selecting Economy (ECO), and relying on the motor to help
slow the vehicle, drivers may extend their driving range. When
switching between ECO and Drive, drivers may notice slight differ-
ences in the amount of pressure needed on the brake pedal to
slow or stop the vehicle. The instrument panel will indicate a neg-
ative amperage, when the high voltage battery is being replen-
ished. Regen is reduced when the high voltage battery State of
Charge (SOC) is above 95% and at low temperatures. During these
times of reduced regen, additional brake input may be required.
WARNING
Do not turn off the ignition key while driving. Without vehicle
power, steering and braking are less effective.

2.3.3 Parking Brake
To engage the parking brake, ensure the vehicle is at a complete
stop and pull the parking brake hand lever backwards into an
upwards position. Do not press the release button while engaging
the parking brake.
To disengage the parking brake, place your foot on the brake
pedal and lift the parking brake hand lever while pressing the but-
ton on the end of the lever. Then push the lever down to its home
position. Ensure that the parking brake indicator is no longer on
prior to driving.
WARNING
Failure to apply the parking brake may allow the vehicle to
roll, potentially causing property damage and personal
injury.
2.3.4 Anti-Lock Braking System (ABS)
When slowing or stopping the vehicle, apply steady pressure on
the brake pedal with your foot, and do not pump the brakes when
the anti-lock braking system (ABS) becomes active. The ABS per-
forms best when steady pressure is applied to the brake pedal.
Pumping the brakes will increase the stopping distance.
2.3.5 Electric Power Steering (EPS) System
The vehicle is equipped with an electric power steering system,
which helps the steering action be light and smooth. Power steer-
ing is automatically activated after the vehicle is started.
If the EPS indicator light comes on, the EPS system is faulty and
requires immediate attention. Do not drive the vehicle until it is
repaired.
2.4 Driving Tips
2.4.1 Weather and Cruising Range
Temperature changes in the operating environment affect the
high voltage battery capacity. Colder temperatures cause a
decrease in the battery capacity and a corresponding decrease in
the cruising range of the vehicle. This is normal and should be
expected. Use of the air conditioning or heating system will also
affect the cruising range.
NOTICE
At low temperatures, the vehicle performance will be reduced
until the battery comes up to temperature through either pre-
conditioning (charging) or driving.
