556 7-2. Steps to take in an emergency
WARNING
Do not lean over the 12-volt battery.
●
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 support, terminals,
and other battery-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 Lexus dealer as soon as possible.
If the 12-volt battery is deteriorating, con-
tinued use may cause the 12-volt battery
to emit a malodorous gas, which may be
detrimental to the health of passengers.
When exchanging the 12-volt battery
■
When the vent plug and indicator are
●
close to the hold down clamp, the bat-
tery fluid (sulfuric acid) may leak.
For information regarding 12-volt bat-
●
tery replacement, contact your Lexus
dealer.
Make sure to replace the 12-volt bat-
●
tery with one designed for this vehicle.
Otherwise, hydrogen gas may enter
the vehicle, possibly causing a fire or
explosion.
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
vehicle interior, and there is the possi-
ble danger of the gas igniting and
exploding.
