WARNING
●In the event that battery fluid 
comes into contact with the skin 
or eyes, immediately wash the 
affected area with water and 
seek medical attention. Place a 
wet sponge or cloth over the 
affected area until medical 
attention can be received.
●Always wash your hands after 
handling the 12-volt battery sup-
port, terminals, and other bat-
tery-related parts.
●Do not allow children near the 
12-volt battery.
■After recharging the 12-volt 
battery
Have the 12-volt battery 
inspected at your Toyota dealer 
as soon as possible.
If the 12-volt batter y is deteriorat-
ing, continued use may cause the 
12-volt battery to emit a malodor-
ous gas, which may be detrimen-
tal to the health of passengers.
■When replacing the 12-volt 
battery
●When the vent plug and indica-
tor are close to the hold down 
clamp, the battery fluid (sulfuric 
acid) may leak.
●For information regarding 
12-volt battery replacement, 
contact your Toyota dealer.
●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 
possible danger of the gas ignit-
ing and exploding.
NOTICE
■When handling jumper cables
When connecting the jumper 
cables, ensure that they do not 
become entangled in the cooling 
fan or belt.
■To prevent damaging the 
vehicle
The exclusive jump starting termi-
nal 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.
