◆Using Eco drive mode
Using Eco drive mode (→P. 181) makes torque generation less
aggressive than normal when stepping on the accelerator pedal,
leading to improvement in fuel economy.
Also, is displayed on the air conditioning screen, indicating
the switch to ECO HEAT/COOL mode ( →P. 260).
◆Air conditioning system on/off
● Turn off the air conditioning sy stem operation switch except
when necessary to help curb fuel consumption.
In summer: When the ambient temper ature is high, use the recircu-
lated air mode. This decreas es the load on the air con-
ditioning system.
In winter: Avoid excess heating. Use the seat heater to minimize
the need for cabin heating ( →P. 268).
● By pushing , ECO HEAT/COOL mode is turned on. This
helps curb fuel consumption even with the air conditioning system
turned on.
◆Checking tire inflation pressure
Make sure to check the tire infl ation pressure frequently. Improper
tire inflation pressure can cause poor fuel economy.
Additionally, snow tire s have more rolling friction and their use on
dry roads lead to poor fuel econom y. Use tires that are appropriate
for the season.
◆Luggage
Avoid carrying unnecessary luggage and unload excess weight in
order avoid poor fuel ec onomy. Installing a large roof rack will also
reduce fuel economy.
