pin wiring harness. Use a factory approved trailer har-
ness and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to the vehicle

NOTE:
•Steps 1 through 4 are requirements that must be met
before pressing the NEUTRAL (N) button, and must
continue to be met until the shift has been completed.
If any of these requirements are not met before press-
ing the NEUTRAL (N) button or are no longer met
during the shift, then the NEUTRAL (N) indicator light
will flash continuously until all requirements are met
or until the NEUTRAL (N) button is released.
•The ignition switch must be in the ON/RUN position
for a shift to take place and for the position indicator
lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no
position indicator lights will be on or flashing.
•A flashing NEUTRAL (N) position indicator light
indicates that shift requirements have not been met.
•If the vehicle is equipped with Quadra-Lift™ air
suspension, the engine should be started and left
running for a minimum of 60 seconds (with all the
doors closed) at least once every 24 hours. This process
allows the air suspension to adjust the vehicle’s ride
height to compensate for temperature effects.

nected to the tow vehicle.
2. Firmly apply the parking brake.
