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.
