More Driving Tips and Techniques Driving Habits Wrong driving habits must be corrected and the recommendations on economic driving should be followed. The following driving factors affect fuel consumption: • excessive speed and unnecessary fast acceleration • long periods of idling • driving with foot resting on the (manual transmission) clutch pedal General Condition Other factors affecting fuel consumption are related to loads and type of roads on which the vehicle operates. It is not always possible to choose the most adequate road, but it must be kept in mind that the ideal road is the one that allows a steady speed in high gear, without requiring frequent braking and acceleration. The following general conditions can affect fuel consumption: • overload • unbalanced load • very high load • inadequate roads • traffic conditions Safe Driving Operating Instructions NOTE: The following recommendations are merely informative and do not cover all safety precautions. Safe driving is, above all, the responsibility of the driver. The safe operation of a vehicle is not just following the established traffic rules, but should also include: maintaining the vehicle in good mechanical condition, and properly operating the engine, transmission, and brakes. The following guidelines will help you to drive the vehicle safely: • Make a thorough inspection of the vehicle, daily and weekly. See “Driver's Check List,” Page 12. • Ensure that windows, mirrors, and lights are clean. • Check all tires for damage and correct inflation pressure. • Adjust the seat to a comfortable driving position, for easy access to pedals and vehicle controls. • Adjust rear view mirrors. • Always use the safety belts. • Do not exceed the GVWR. • Proportionally distribute loads on the frame. – 100 – PB1318 3/01 Model 330

Operating Instructions • Always keep the brakes adjusted and in proper condition. See page 154. • Obey speed limits and all traffic signals. • When driving downhill, select one gear lower than the gear you would use going up the hill. And use the brakes properly—do not ride them. • Do not exceed maximum governed engine speed (as specified in the Engine Operation and Maintenance Manual). WARNING! Do not exceed the specified load rating. Overloading can result in loss of vehicle control and serious personal injury, either by causing component failures or by affecting vehicle handling. Exceeding load ratings can also shorten the service life of the vehicle. • The components of your vehicle are designed to provide satisfactory service if the vehicle is not loaded in excess of either the gross vehicle weight rating (GVWR), or the maximum front and rear gross axle weight ratings (GAWRs). (Axle weight ratings are listed on the driver's door edge.) More Driving Tips and Techniques NOTE: For your safety and the safety of others, follow routine and periodic maintenance schedules for all components on your vehicle. See Table 3, “Maintenance Schedule,” Page 124 Air Suspension Height/Air Pressure Your vehicle may have an air suspension. A deflation switch on the dash allows you to exhaust the air in the suspension, which allows you to lower the height of your vehicle for loading. On tractors, the deflate switch allows you to lower the fifth wheel to slide under a trailer. A guard on the switch prevents you from accidentally deflating the suspension. WARNING! Do not operate the Air Suspension Deflate Switch (Dump Valve) while driving. Sudden deflation while your vehicle is moving can affect handling and control and could lead to an accident. Use this switch only when your vehicle is not moving. CAUTION: Operating a vehicle with air suspension bags either overinflated or underinflated may cause damage to driveline components. If a vehicle must be operated under such conditions, do not exceed 5 mph (8 km/h). Model 330 PB1318 3/01 – 101 –
