Maintenance When Trailer Towing

Your vehicle will need service more often when you are
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (do not overfill),
engine oil, drive belt, cooling system and brake system.
Each of these is covered in this manual, and the Index
will help you find them quickly. If you are trailering, it is a
good idea to review this information before you start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.

Engine Cooling When Trailer Towing

Your cooling system may temporarily overheat during
severe operating conditions. See Engine Overheating on
page 5-29.
