CDifficulty 3/5

When using jump leads on a vehicle whose manufacturer permits that procedure, which precaution should you follow?

Correct answer

Follow the prescribed procedure and do not lean over the battery during starting.

Follow the manufacturer’s procedure using compatible equipment and specified connection points. Keep flames and sparks away and do not lean over the battery during starting. Prevent the clamps from causing a short circuit. A manufacturer-specified ground connection is intentional contact, unlike accidentally touching metal with a connected clamp. Voltage is measured in volts and current in amperes; do not use an incompatible voltage source or a damaged or frozen battery.
