Pontiac 2004 Grand Prix - Manual (Page 280)

Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See
Part A: Scheduled Maintenance
Services on page 6-4 for more information. Things that
are especially important in trailer operation are automatic
transaxle fluid (don’t overfill), engine oil, drive belts,
cooling system and brake system. Each of these is
covered in this manual, and the Index will help you find
them quickly. If you’re 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 5-29 .
