NOTE: Vehicles equipped with LPG fuel systems will only start in ALT fuel mode with Engine Coolant Temperature (ECT) temperatures above -13°F (-25°C). Below this point liquid propane cannot vaporize. It may be necessary to bring vehicle to normal operating temperature in gasoline mode before switching to or restarting in ALT fuel mode.

Apply parking brake, and place shift lever in Park (A/T) or Neutral (M/T) position. Block drive wheels. Turn off all electrical accessories. Ensure engine is at normal operating temperature. If vehicle is equipped with an auxiliary powertrain control system (RPM control), it must be turned off when performing any self-test procedure. Connect appropriate test equipment to vehicle as follows.
