Driving in Flooded Areas
Avoid driving through flooded areas unless you are sure the water is no higher than the bottom of the wheel hub. Drive through any water slowly. Allow adequate stopping distance because brake performance may be reduced.
After driving through water, dry the brakes by gently applying them several times while the vehicle is moving slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified. Under-inflation may overheat or damage the tires.
Do not install worn-out or damaged tires, which may reduce traction or adversely affect vehicle handling. This could lead to sudden tire failure that may cause loss of vehicle control resulting in an accident.
Information
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 in order to conserve fuel when driving on the highway. Be sure to check both the engine coolant level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may overheat the engine.
