Highway driving
Tires
Adjust the tire inflation pressure, as specified. Under-inflation may overheat or damage the tires.
Do not install worn-out or damaged tires, which may reduce traction or fail.
Never over-inflate your tires above the maximum inflation pressure, as specified on your tires.
Fuel, engine coolant and engine oil
Driving at higher speeds on the highway consumes more fuel and is less efficient than driving at a slower, more moderate speed. Maintain a moderate speed to conserve fuel when driving on the highway.
Check both the engine coolant level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may overheat the engine.
