WARNING!
Do not connect the jumper cable to the negative
(-yf post of the discharged battery. The resulting
electrical spark could cause the battery to
explode and could result in personal injury.
CAUTION!
Do not run the booster vehicle engine above
2,000 RPM since it provides no charging benefit,
wastes fuel, and can damage booster vehicle
engine.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices, etc.yf
Eventually, if plugged in long enough without
engine operation, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent the engine from starting.
