Maintenance When Trailer Towing

The vehicle will need service more often when it pulls a
trailer. See. Scheduled Maintenance on page 6-4 for
more information. Things that are especially important in
trailer operation are automatic transaxle fluid; which
should not be overfilled; engine oil, drive belt(s),
and cooling and brake systems. Each of these is
covered in this manual, and the Index will help you find
them quickly. If trailering, it is a good idea to review
this information before starting on a trip.
Check periodically to see that all hitch nuts and bolts
are tight.

Engine Cooling When Trailer Towing

The cooling system may temporarily overheat during
severe operating conditions. See Engine Overheating on
