Vehicle Damage Warnings

CAUTION:
^ Do not remove the PCV system from the engine. Operating engine without the Positive Crankcase Ventilation (PCV) system will reduce both fuel economy and engine ventilation. This will weaken engine performance and shorten engine life.
^ The canister vent solenoid must not be energized for more than nine minutes at one time. Once the canister vent solenoid is energized and de-energized, adequate time must be allowed for the component to cool adequately. Failure to allow the component to cool may create a false failure in the diagnostics, causing unnecessary repairs.
^ The evaporative emission system must not be pressurized to more than 3.48 kPa (14 inches H2O) or damage to the evaporative emission system may occur.
