◆Air conditioning
●Turn the “A/C” switch (
*1 • *2) off when it is
not needed. Doing so can help reduce excessive electricity and
fuel consumption.
In summer: When the ambient temperature is high, use the recir-
culated air mode. Doing so will help to reduce the burden on th e
air conditioning system and reduc e electricity and fuel consump-
tion as well.
In winter: Avoid excessive and unnecessary use of the heater.
Usage of the heated steering w heel (if equipped) and seat heat-
ers is effective. ( P. 5 2 6 )
● Using the Remote Air Conditioning System ( P. 522) while the
charging cable is connected to the vehicle can reduce electrici ty
consumption immediately after st arting off by operating air condi-
tioning mainly using electricity from an external power source.
● When setting the timer, selecting the start time setting mode a nd
setting “Climate Prep” to “On” c an reduce electricity consumption
immediately after starting off by operating air conditioning be fore
charging is completed. ( P. 157)
*1: Vehicles with 7-inch display
*2: Vehicles with 11.6-inch display
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. If t here is
improper tire inflation pressur e in the tires, the EV driving range will
become shorter, and fuel consumption when in HV mode will
increase.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead t o increased fuel and electricity consumptio n.
◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carry-
ing unnecessary luggage. Installing a large roof rack will also cause
poor fuel economy.
◆Warming up before driving
Since the gasoline engine starts up and cuts out automatically,
warming up is not necessary.
