Maintenance When Trailer Towing
Your vehicle will need service more often when
you are pulling a trailer. See Scheduled
Maintenance on page 391 for more information.
Things that are especially important in trailer
operation are automatic transaxle fluid (don't
overfill), engine oil, axle lubricant, 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's 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 297.
Changing a Tire When Trailer Towing
If you get a flat tire while towing a trailer, be
sure to secure the trailer and disconnect it from
the vehicle before changing the tire.
