2008 DODGE RAM 3500 GAS towing

To minimize the possibility of catalyst damage:
²Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
²Do not try to start the engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idling or malfunctioning operating conditions.
Emission-Related Components
Positive Crankcase Valve (PCV)
Proper operation of the crankcase ventilation system
requires that the PCV valve be free of sticking or plug-
ging from deposits. Deposits can accumulate in the PCV
valve and passages with increasing mileage. Have the
PCV valve, hoses, and passages checked for proper
operation at the intervals specified. If the valve is
plugged or sticking, replace with a new valveÐdo not
attempt to clean the old PCV valve!Check the ventila-
tion hoses for indications of damage, weepage or plug-
ging with deposits. Replace if necessary.
Maintenance-Free Battery
The top of the maintenance-free battery is permanently
sealed. You will never have to add water, nor is periodic
maintenance required.
