STARTING AND OPERATING
WARNING!
An improperly adjusted weight-distributing
hitch system may reduce handling, stability,
braking performance, and could result in a
collision.
Weight-distributing hitch systems may not be
compatible with surge brake couplers. Consult
with your hitch and trailer manufacturer or a
reputable Recreational Vehicle dealer for
additional information.
RECOMMENDED DISTRIBUTION HITCH
ADJUSTMENT
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 vehicle to be ready to connect to
the trailer (do not connect the trailer).
3. For vehicles equipped with Quadra-Lift air
suspension, using the touchscreen radio
settings, enable tire jack mode. Tire jack mode
will be canceled and 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 the ground;
this is height H1.
Measuring Height (H)
5. Attach the trailer to the vehicle without the
weight distribution 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 manufacturers'
recommendations so that the height of the
front fender is approximately (H2-H1)/2+H1
(about 1/2 the difference between H2 and H1
above normal ride height [H1]).
8. Use the 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 manufacturers'
recommendations have been met.
9. The vehicle can now be driven.
