Coolant Level
The coolant recovery bottle provides a visual method for
checking the coolant level without removing the pressure
cap.
With the engine warmed up, the coolant level should be
between MIN and MAX on the coolant recovery bottle.When additional coolant is needed to maintain the
proper level, it should be added to the coolant recovery
bottle.
Points to Remember
•
Do not overfill the bottle.
•Check coolant freeze point in the coolant bottle. If
antifreeze needs to be added, contents of the coolant
bottle also must be protected against freezing.
•If frequent coolant additions are required, or if the
level in the bottle does not drop when the engine cools,
the cooling system should be pressure tested for leaks.
•Maintain coolant concentration at 50% HOAT ethylene
glycol engine coolant (minimum) and distilled water
for proper corrosion protection of your engine which
contains aluminum components.Coolant Recovery Bottle

the vehicle is not going to be driven in the next 3
weeks, follow the battery recharge procedure in the
Service Manual, then disconnect the battery at the
negative terminal or use the save feature described in
Maintaining your Vehicle section under the Mainte-
nance Procedures sub-section, within Maintenance-
Free Battery.
CAUTION!
Use care when disconnecting the remote positive
cable. It is connected to the battery and can short out
to any metal on the vehicle. Always tape or wrap the
exposed cable end to prevent electrical shorts.
•Disconnecting the battery causes the engine control
system to lose memory of some“learned”functions,
unless using the Battery Save feature described inMaintaining your Vehicle section under the Mainte-
nance Procedures sub-section, within Maintenance-
Free Battery. The engine may run rough when first
started after a battery disconnect until the control
module“relearns”these functions.
Check the battery every 4 to 6 weeks to ensure that the
voltage is above 12.40. Voltage will drop more rapidly
in hot temperatures. If battery voltage drops below
12.40, follow the battery recharge procedure in the
Service Manual.
•Check that the radiator coolant level of protection is to
at least -20°F (-29°C).
•Block the wheels. Do not apply the Parking Brake.
•Make sure that all tires are inflated to the optimum
pressure, (29 PSI).

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.

NOTE:IfANYof these apply to you then change your
engine oil every 3,000 miles (5,000 km) or 3 months,
whichever comes first and follow schedule B of the
“Maintenance Schedules”section of this manual.
NOTE:IfANYof these apply to you then flush and

NOTE:Most vehicles are operated under the conditions
listed for ScheduleB.Second is Schedule“A”. It is for vehicles that are not
operated under any of the conditions listed under Sched-
uleB.
Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.
NOTE: Under no circumstances should oil change
intervals exceed 6 months or 6,000 miles, whichever
comes first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.

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.
