2-1. Driving procedures
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. (P. 5 5 0 )
■For efficient use
●Select the D position when driving. 
In the N position, the gasoline engine op erates but electricity cannot be gener-
ated. The hybrid battery (traction battery) will discharge, requiring unnecessary
engine power to recharge.
●Drive your vehicle smoothly. 
Avoid abrupt acceleration and deceleration. Gradual acceleration and decel-
eration will make more effective use of the electric motor (traction motor) with-
out having to use gasoline engine power.
●Avoid repeated acceleration. 
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving with
the accelerator pedal slightly released.
●Select the P position when parking. 
In the N position, the hybrid battery (traction battery) does not recharge. 
Leaving the N position selected for an extended period of time may discharge
the hybrid battery. The vehicle cannot ru n if the hybrid battery is discharged.
■Environment-friendly driving
■Customization
Settings for the Eco Driving Indicator Light can be changed. 
(Customizable features P. 5 7 2 )
During environment-friendly acceleration
operation (Eco driving), the Eco Driving Indi-
cator Light will turn on. When the accelerator
pedal is depressed excessively, and when the
vehicle is stopped, the light turns off.
The Eco Driving Indicator Light will operate
when the vehicle is being driven with the shift
position in D. The indicator will not operate
when the vehicle is in power mode or EV
drive mode. ( P. 1 5 0 ,
