696 STARTING AND OPERATING
NOTE: For all towing conditions, we recommend towing
with tow haul mode engaged.
All Other 1500(Non-Air Suspension)/2500/3500 Trucks
1. Position the truck to be ready to connect to the trailer
(do not connect the trailer).
NOTE: For Ram 2500/3500 trucks equipped with rear air
suspension, normal ride height or alternate ride height
can be used. The vehicle must remain in the engine
running position while attaching a trailer for proper
leveling of the air suspension system. It may not be
possible to enter alternate ride height while lightly
loaded.
2. Measure the height of the top of the front wheel
opening on the fender to ground, this is height H1.
3. Attach the trailer to the vehicle without the weight
distribution bars connected.
4. Measure the height of the top of the front wheel
opening on the fender to ground, this is height H2.
5. Install and adjust the tension in the weight distribut-
ing bars so that the height of the front fender is
approximately (H2-H1)/2+H1 (about 1/2 the differ-
ence between H2 and H1 above normal ride height
[H1]).
