Before recharging

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

and explosive. Therefore, observe the following precautions 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

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 and then attempt to

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

cedure.)

●

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

your Lexus dealer.
