lowing 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 char-
ger is off when connecting and discon-
necting the charger cables to the 12-volt

● Start the engine <hybrid system> with the
engine switch <power switch> in ACCES-
SORY mode. The engine <hybrid sys-
tem> may not start with the engine switch

mally from the second attempt.
● The engine switch <power switch> mode
is recorded by the vehicle. If the 12-volt
