■ Before recharging
When recharging, the battery produces
hydrogen gas which is flammable and
explosive. Therefore, observe the following
precautions before recharging:
● If recharging with the battery installed on
the vehicle, be sure to disconnect the
ground cable.
● Make sure the power switch on the char-
ger is off when connecting and discon-
necting the charger cables to the battery.
■ After recharging/reconnecting the bat-
tery
● The engine may not start. Follow the pro-
cedure below to initialize the system.
1 Shift the shift lever to P.
2 Open and close any of the doors.
3 Restart the engine.
● Unlocking the doors using the smart
access system with push-button start may
not be possible immediately after recon-
necting the battery. If this happens, use
the wireless remote control or the
mechanical key to lock/unlock the doors.
● Start the engine with the engine switch in
ACCESSORY mode. The engine may
not start with the engine switch turned off.
However, the engine will operate nor-
mally from the second attempt.
● The engine switch mode is recorded by
the vehicle. If the battery is reconnected,
the vehicle will return the engine switch
mode to the status it was in before the
battery was disconnected. Make sure to
turn off the power before disconnect the
battery. Take extra care when connecting
the battery if the engine switch mode
prior to discharge is unknown.
If the system will not start even after multiple
attempts at all the methods above, contact
your Lexus dealer.
WARNING
■ When filling the reservoir
Take care as brake fluid can harm your
hands and eyes and damage painted sur-
faces.
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.
NOTICE
■ If the fluid level is low or high
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.
