STARTING AND OPERATING
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 5mph (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 FCA recommen
-
dations 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]).
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.
NOTE:
For all towing conditions, we recommend towing
with tow haul mode engaged.
