
Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, observe the following precautions before
recharging:

If recharging with the 12-volt battery installed on the vehicle, be sure to
disconnect the ground cable.

Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the 12-volt battery.

After recharging/reconnecting the 12-volt battery
The hybrid system may not start. Follow one or both of the following proce-
dures:

After opening and closing the driver's door, wait 10 seconds and then
attempt to start the hybrid system. (If the system does not start the first
time, repeat the procedure.)

With the shift lever in P and the "POWER" switch off, open and close
any door and then attempt to start the hybrid system.
If the system will not start even after multiple attempts at both methods,
contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional.
