Severe conditions in the manual: repeatedly driving short distances of less than 5 miles (8 km) in normal temperatures, or less than 10 miles (16 km) in freezing temperatures; extensive engine idling or low-speed driving for long distances; driving on rough, dusty, muddy, unpaved, graveled or salt-spread roads; driving in areas that use salt or other corrosive materials, or in very cold weather; driving in heavy dust; driving in heavy traffic; repeated driving on uphill, downhill or mountain roads; towing or camping, or driving with a load on the roof; use as a patrol car, taxi or other commercial vehicle; frequent high-speed driving or rapid acceleration and deceleration; frequent stop-and-go driving. Kia also recommends the severe schedule after 10 years or 100,000 miles (150,000 km).
