7. Press and hold the brake pedal.
8. To start the vehicle
8.1. Gasoline vehicles: Turn the key to the START position and hold it there until the engine starts.
Activate the choke as necessary. If the engine does not start after 10-15 seconds, release the key
and repeat the procedure. Once the engine starts, release the key and it will return to the ON posi-
tion. The engine will idle in neutral.
8.2. Diesel vehicles: To preheat glow plugs in cold weather, turn the key to the PREHEAT position and
hold it there for 10-15 seconds. Turn the key to the START position and hold it there until the engine
starts. If the engine does not start after 10-15 seconds, turn the key to the OFF position and repeat
the procedure. Once the engine starts, release the key and it will return to the ON position. The
engine will idle in neutral.
9. Release the park brake.
10. Keep the brake pedal engaged, and select direction of travel by placing the shift handle in the desired
position (Figure 4 or Figure 5, Page 11). The engine must be at idle before the shift handle is moved.
A buzzer will sound as a warning when the Forward/Reverse handle is in the REVERSE position.
11. Release the brake pedal completely, and then slowly press the accelerator pedal. As the accelerator
pedal is pressed, the vehicle will begin to move. Vehicle speed will increase as the accelerator is pressed
until full speed is reached. All-wheel drive will automatically drive the appropriate wheel(s) as required.
See following WARNING.
ý WARNING
• Operator must control vehicle speed when going downhill.
• Never shift the vehicle out of the FORWARD position while going downhill. If you do, you will
not be able to shift into the REVERSE position or back into the FORWARD position until
stopped.
• Press the brake pedal as necessary and press the accelerator pedal partially when
descending a hill. With the accelerator pedal partially pressed, the governor will cause the
engine to assist the brakes in controlling downhill speed.
ALL-WHEEL DRIVE (AWD) OPERATION
All HUV 4421-G and HUV 4421-D vehicles feature an all-wheel drive (AWD) system. The AWD system auto-
matically directs power to the wheel, or wheels, that have the most traction, providing optimum traction at all
times. For example, if all wheels except the rear passenger-side wheel lose traction, then power will be
directed to the rear passenger-side wheel. The all-wheel drive vehicle can adapt traction for a wide variety of
driving surfaces and conditions. See following WARNING.
ý WARNING
• When servicing the vehicle with part of the vehicle on jack stands, do not operate the engine
with the Forward/Reverse handle in either the FORWARD or REVERSE position. The all-wheel
drive system will engage any wheel(s), front or rear, with traction. See Figure 2 on page 9.
• The diameter of all tires on the vehicle must be equal, otherwise the all-wheel drive system
will not operate as intended and could result in severe personal injury or death. Never install
tires of different diamters on the vehicle.
