charge the hybrid battery (trac-
tion battery) from an external
power source before using the

(traction battery) has not been com-
pleted, the vehicle can be driven.

the vehicle cannot be driven in EV
mode or AUTO EV/HV mode or the

used depending on the situation
(  P.79) even if in EV mode or
AUTO EV/HV mode, and the gaso-
line engine is provided on board as
a power source for driving in HV
mode, it is needed to refueling the
vehicle.
Check the fuel amount and refill
immediately when the fuel level
becomes low. ( P.279)

long time
