RECOMMENDED DISTRIBUTION HITCH
ADJUSTMENT
Towing With Air Suspension — If Equipped
1.
Verify that the vehicle is at the normal ride height.
NOTE:
The vehicle must remain in the engine run position with all
doors closed while attaching a trailer for proper leveling of
the air suspension system.
2.
Position the truck to be ready to connect to the trailer
(do not connect the trailer).
3.
Enable tire jack mode through the instrument cluster
or touchscreen radio settings. Tire jack mode will be
canceled and the procedure must be restarted if the
vehicle is driven at speeds above 5 mph (8 km/h).
4.
Measure the height from the top of the front wheel
opening on the fender to ground; this is height H1.
Measuring Height (H)
5.
Attach the trailer to the vehicle without the
weight-distributing bars connected.
6.
Measure the height from the top of the front wheel
opening on the fender to the ground; this is height H2.
7.
Install and adjust the tension in the
weight-distributing bars per the manufacturer's
recommendations so that the height of the front
fender is approximately (H2-H1)/3+H1
(about 1/3 the difference between H2 and H1 above
normal ride height [H1]).
STARTING AND OPERATING
8.
Use the instrument cluster or touchscreen radio
settings and switch off tire jack mode. Make sure the
truck returns to normal ride height. Perform a visual
inspection of the trailer and weight-distributing hitch
to confirm the manufacturer's recommendations
have been met.
9.
The truck can now be driven.
