If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately.
If you still experience discomfort, see a doctor.

It is normal for the brake fluid level to go down slightly as the brake pads
wear out or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, there may be a serious problem.

■Before charging
When charging, the 12-volt battery produces hydrogen gas which is flamma-
ble and explosive. Therefore, observe the following precautions before
charging:
●If charging with the 12-volt battery installed on the vehicle, be sure to dis-
connect 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.
Remove the 12-volt battery
maintenance cover.

Maintenance and care
■After charging/reconnecting the 12-volt battery
●Unlocking the doors using the smart key system may not be possible
immediately after reconnecting the 12-volt battery. If this happens, use
the wireless remote control or the mechanical key to lock/unlock the
doors.
●Start the hybrid system with the “POW ER” swi tc h in ACC ESSORY mode.
The hybrid system may not start with the “POWER” switch turned off.
However, the hybrid system will operate normally from the second
attempt.
●The “POWER” switch mode is recorded by the vehicle. If the 12-volt bat-
tery is reconnected, the vehicle will return the “POWER” switch mode to
the status it was in before the 12-volt battery was disconnected. Make
sure to turn off the power before disconnect the 12-volt battery. Take
extra care when connecting the 12-volt battery if the “POWER” switch
mode prior to discharge is unknown.
●Restart the hybrid system, depress the brake pedal, and confirm that it is
possible to shift into each shift position.
If the system will not start even after multiple attempts at all methods above,
contact your Toyota dealer.
