Towing Tips
Before setting out on a trip, practice turning, stopping and backing the trailer in an area away from heavy traffic.
If using a manual transmission vehicle for trailer towing, all starts must be in FIRST gear to avoid excessive clutch slippage.
Towing Tips - Automatic Transmission
The "D" range can be selected when towing. However, if frequent shifting occurs while in this range, the "TOW HAUL" or "OD/OFF" range should be
selected.
NOTE: Using the "TOW HAUL" or "OD/OFF" range while operating the vehicle under heavy operating conditions will improve
performance and extend transmission life by reducing excessive shifting and heat build up. This action will also provide better engine
braking.
The automatic transmission fluid and filter should be changed if you REGULARLY tow a trailer for more than 45 minutes of continuous operation. See
