Maintenance When Trailer Towing
The vehicle needs service more often when pulling a trailer. See Scheduled Maintenance for more information. Things that are especially important in trailer operation are automatic transmission fluid, engine oil, belts, cooling system and brake system. It is a good idea to inspect these before and during the trip.
Check periodically to see that all hitch nuts and bolts are tight.
