WARNING
■After recharging the 12-volt battery
Have the 12-volt battery inspected at any authorized Lexus retailer or Lexus authorized repairer, or any reliable
repairer as soon as possible. If the 12-volt battery is deteriorating, continued use may cause the 12-volt battery to emit a
malodorous gas, which may be detri- mental to the health of passengers.
■When exchanging the 12-volt battery
After exchanging, securely attach the exhaust hose and exhaust hole plug to
the exhaust hole of the exchanged 12- volt battery. If not properly installed, gases (hydrogen) may leak into the vehi-
