Fuel Economy Fuel Economy Factors The following factors can lower your vehicle's fuel economy: ● Improving Fuel Economy Vehicle Maintenance ● Aggressive driving (hard acceleration and braking) Excessive idling, accelerating and braking in stop-and-go traffic Cold engine operation (engines are more efficient when warmed up) Driving with a heavy load or the air conditioner running Improperly inflated tires ● ● ● A properly maintained vehicle maximizes fuel economy. Poor maintenance can significantly reduce fuel economy. Always maintain your vehicle according to the maintenance messages displayed on the information display (see Owner's Maintenance Checks on page 417). For example: ● Keep your vehicle clean － In particular, a build-up of snow or mud on your vehicle's underside adds weight and rolling resistance. Frequent cleaning helps your fuel economy. Before Driving ● Use the required engine oil (see page 420). Maintain proper tire inflation － An underinflated tire increases ''rolling resistance,'' which reduces fuel economy. Avoid carrying excess weight in your vehicle － It puts a heavier load on the engine, increasing fuel consumption. ● ● CONTINUED 359 2010 RDX
