WARNING
■When replacing the 12-volt battery
After replacing, securely attach the exhaust hose and exhaust hole plug to
the exhaust hole of the replaced 12-volt battery. If not properly installed,
gases (hydrogen) may leak into the vehicle interior, and there is the possi-
ble danger of the gas igniting and exploding.

When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fan or engine drive belt.
■To prevent damaging the vehicle
The exclusive jump starting terminal is to be used when charging the 12-volt
battery from another vehicle in an emergency. It cannot be used to jump
start another vehicle.
