Dodge 2006 ZB Viper - Manual (Page 219)

Headlight Aiming
The headlights on your new Viper were aimed at the
factory. The factory setting was made at a no load setting.
A great increase in weight will change the aiming and it
may be necessary to readjust the headlights if you
typically carry an excessive amount of weight in the rear
compartment or otherwise suspect misalignment.
Aiming Check
Each headlight assembly can be adjusted up and down
only. No left to right adjustment is necessary. To check,
proceed as follows:
1. Fill the fuel tank and park the vehicle on level ground.
A driveway is not normally level. If in doubt and you
have no way to check levelness, do not attempt to adjust
the headlights.
2. Mark the position of the headlights on a wall prior to
loading the vehicle. Load the rear compartment with the
items you normally carry. Have someone sit in the
driver’s seat who is about the same weight as the person
who drives the vehicle.
3. Push down on the front and rear of the vehicle several
times to make sure that the suspension has settled.
4. Then readjust the headlights to the original position.
NOTE: If any further adjustments are necessary, contact
your dealership.
