Driving Instructions

5.Make sure wheels are turned in desired direction and nothing is in your path.

6.Make sure the Forward/Reverse handle is in the NEUTRAL position.

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.

ýWARNING

•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.

ýWARNING

•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.
