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
trunk 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 trunk 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.

At Each Stop for Fuel
•Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required.
Once a Month
•Check tire pressure and look for unusual wear or
damage.
•Inspect the battery and clean and tighten the terminals
as required.
•Check the fluid levels of coolant reservoir, brake
master cylinder, power steering and transmission and
add as needed.
•Check all lights and all other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the exhaust system.
•Inspect the brake hoses.
•Inspect the suspension components.
•Lubricate door hinges and check springs.
•Check the engine coolant level, hoses, and clamps.
•Check power steering fluid level.
