Roadside Emergencies

starting stud located in the engine compartment, near the washer fluid
bottle. Do not use fuel lines, engine rocker covers or the intake manifold
as grounding points.

negative (-) terminal of the battery to be jumped. A spark may
cause an explosion of the gases that surround the battery.

both engines, or any fuel delivery system parts.
