• For night use, the vehicle must be equipped with headlights, taillights, and reflectors. • The vehicle is not specially equipped for handicapped persons: – Be sure all passengers are capable of securing themselves in a moving Husqvarna vehicle before allowing them to ride in one.
Driving Instructions WARNING • To help prevent overturning the vehicle, drive slowly straight up and down slopes. Avoid driving the vehicle on slopes exceeding 20% incline. • Avoid stopping a loaded vehicle on a hill. If a loaded vehicle must be stopped on a hill, avoid sudden starts or rolling backwards and stopping suddenly.
ALL-WHEEL DRIVE (AWD) OPERATION The Husqvarna HUV 5420 DX features an all-wheel drive (AWD) system. The AWD system automatically 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.
Loading and Unloading Cargo CAUTION • When stopped on a hill, use the brake pedal to hold your position. Do not use the accelerator pedal to hold position. PARKING AND LEAVING THE VEHICLE After stopping the vehicle, firmly set the park brake. Make sure it is fully engaged. This will prevent the vehicle from rolling.
