2004 Dodge Caravan Owner's Manual - Page 276

276 STARTING AND OPERATING • The trailer tongue load must be considered as part of the combined weight of occupants and cargo, and should never exceed the weight referenced on the Tire and Loading Information placard. Refer to the Tire- Safety Information Section in this manual. • The "D" range can be selected when towing. However, if frequent shifting occurs while in this range, the "3" range must be selected. NOTE: Using the "3" range while operating the vehicle under heavy operating conditions will improve performance and extend transaxle life by reducing excessive shifting and heat build up. • Do not attempt to tow a trailer while using a compact spare tire. • Whenever you pull a trailer, regardless of the trailer size, stop lights and turn signals on the trailer are recommended for motoring safety. • The automatic transaxle fluid and filter should be changed if you REGULARLY tow a trailer for more than 45 minutes of continuous operation. See Schedule "B" in section 8 of this manual for transaxle fluid change intervals. NOTE: Check the automatic transaxle fluid level before towing. Fluid discoloration, or a burnt odor, shows the need for a transmission fluid and filter change. WARNING! Connecting trailer brakes to your vehicle's hydraulic brake lines can overload your brake system and cause it to fail. You might not have brakes when you need them and could have an accident.
