SCHEDULED SERVICING — GASOLINE
ENGINE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot
or cold ambient temperatures will influence when the
"Change Oil" or "Oil Change Required" message is dis-
played. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
