RX450h_U_OM0E013U ■
When exchanging the 12-volt battery ●
Use a Central Degassing type 12-volt battery (European Regulations). Also, use 12-volt
batteries with case si zes similar to one prior the exchange and an equivalent 20 hour
rate capacity (20HR) or greater.
• If the sizes differ, the 12-volt battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehicle is not
used is a short time, the 12-volt battery may discharge and hybrid system may not be
able to start. ●
After exchanging, firmly attach the following items to the exhaust hole of the 12-volt
battery.
For details, consult your Lexus dealer. • Use the exhaust hose that was attached to
the 12-volt battery before exchanging and
confirm that it is firmly connected to the
hole section of the vehicle.
• Use the exhaust hole plug included with the
12-volt battery exchanged or the one
installed on the battery prior to the
exchange. (Depending on the 12-volt bat-
tery to be exchanged, the exhaust hole may
be plugged.)
