◆ Air conditioning
Use the air conditioning only when necessary. Doing so can help reduce
excessive fuel consumption.
In summer: When the ambient temperature is high, use the recirculated air
mode. Doing so will help to reduce the burden on the air conditioning system
and reduce fuel consumption as well.
In winter: Turn "A/C" (P. 376) on only when both heating and dehumidifying
are needed, and if only heating is needed, turn "A/C" off. Turning "A/C" on
when unnecessary leads to excessive fuel consumption.
◆
Performing idling stops
Avoid unnecessary idling. Stop the engine when parking the vehicle to
●
reduce excessive fuel consumption, even it is only for a short period of time.
Except in severe environment, such as when the outside temperature is
●
extremely low, warning up the engine before driving in unnecessary. Rather
than idling, it is more efficient to drive the vehicle gently to warm up each
part while avoiding increasing the engine revolutions unnecessarily and
accelerating or decelerating suddenly.
◆
Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack will also cause poor fuel
economy.
◆
Regular maintenance
Make sure to check the tire inflation pressure frequently. Improper tire
●
inflation pressure can cause poor fuel economy. Also, as snow tires can
cause large amounts of friction, their use on dry roads can lead to poor fuel
economy. Use tires that are appropriate for the season and road condi-
tions.
Use oil and fluid of the recommended quality, which affect fuel consump-
●
tion and the life of the vehicle. Also, check oil and fluid periodically.
