Towing Requirements – Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
NOTE:Do not cut or splice wiring into the vehicle’s
wiring harness.
WARNING!
Any work done to the vehicle’s electrical system or
wiring should be performed by a qualified automo-
tive technician. If done improperly it may cause
damage to the electrical system wiring and could
result in serious or fatal injury.
Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer up in an area away from heavy
traffic.
Automatic Transmission — If Equipped
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent
shifting does occur while in DRIVE, select TOW/HAUL
mode or select a lower gear range (using the Electronic
Range Select (ERS) shift control).
NOTE: Using TOW/HAUL mode, or selecting a lower
gear range (using the ERS shift control) while operating
the vehicle under heavy loading conditions will improve
performance and extend transmission life by reducing
excessive shifting and heat build up. This action will also
provide better engine braking.
When towing a loaded trailer up steep grades at low
speeds (20 mph [32 km/h] or below), holding your
vehicle in first gear (using the ERS shift control) can help
to avoid transmission overheating.
