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 tem-
perature is extremely low, warming up the engine before driv-
ing is 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 acceler-
ating 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 conditions.
● Use oil and fluid of the recommended quality, which affect fuel
consumption and the life of the vehicle. Also, check oil and
fluid periodically. (→P. 339)
