Air conditioning on/off

Switch the air conditioning (
Doing so can help control excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode.
Doing so will help to reduce the burden on the air conditioner
and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut
out until the gasoline engine and the interior of the vehicle are
warm, it will consume fuel. Also, fuel consumption can be
improved by avoiding overuse of the heater.
Checking tire inflation pressure
■
Make sure to check the tire inflation pressure frequently.
Improper tire inflation pressure can cause poor fuel consump-
tion.
Also, as snow tires can cause large amounts of friction, their use
on dry roads can lead to poor fuel consumption. Use a tire that is
appropriate for the season.
Luggage
■
Carrying heavy luggage can lead to poor fuel consumption.
Avoid carrying unnecessary luggage. Installing a large roof rack
can also cause poor fuel consumption.
Warming up before driving
■
Since the gasoline engine starts up and cuts out automatically
when cold, warming up the engine is unnecessary. Moreover,
frequently driving short distances will cause the engine to
repeatedly warm up, which can lead to poor fuel consumption.
