04 09.01 JUMP STARTING PROCEDURE 1. If the booster battery is installed in another vehicle, make sure the vehicles are not touching. Turn off all unnecessary lights and accessories. When boosting, use the battery of matching or higher quality. Any other battery may be difficult to jump start with. If jump starting is difficult, charge the battery for several minutes. 2. If required, remove all the vent plugs from the booster and discharged batteries. Lay a cloth over the open vents on the batteries. (This helps reduce the explosion hazard, personal injuries and burns.) 3. If the engine in the vehicle with the booster battery is not running, start it and let it run for a few minutes. During jump starting, run the engine at about 2000 rpm with the accelerator pedal lightly depressed.
