Saturn Coupes/Sedans/Wagons 1991-1998 Repair Guide
Jump Starting Precautions
Be sure that both batteries are of the same voltage. Vehicles covered by this guide and most vehicles on the road today utilize a 12 volt charging system.
Be sure that both batteries are of the same polarity (have the same terminal grounded); in most cases, it is NEGATIVE.
Be sure that the vehicles are not touching or a short circuit could occur.
On serviceable batteries, be sure the vent cap holes are not obstructed.
Do not smoke or allow sparks anywhere near the batteries.
In cold weather, make sure the battery electrolyte is not frozen. This can occur more readily in a battery that has been in a state of discharge.
Do not allow electrolyte to contact your skin or clothing.
