Before recharging

When recharging, the 12 volt battery produces hydrogen gas which is flammable

and explosive. Therefore, before recharging:

●

If recharging with the 12 volt battery installed on the vehicle, be sure to discon-

nect the ground cable.

●

Make sure the power switch on the charger is off when connecting and discon-

necting the charger cables to the 12 volt battery.

■

After recharging/reconnecting the 12 volt battery

In some cases, the hybrid system may not start. Follow one or both of the following

procedures:

●

After opening and closing the driver’s door, wait 10 seconds then attempt to

start the hybrid system. (If the system does not start first time, repeat the proce-

dure.)

●

With the shift lever in “P” and the “POWER” switch is OFF, open and close any

door, then attempt to start the hybrid system.

If the system will not start even after multiple attempts at both methods, contact

your Lexus dealer.
