391-1. Hybrid system1Before drivingnAir conditioningUse the air conditioning only when necessary. 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 con-sumption 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 con-sume fuel. Also, fuel consumption can be improved by avoiding overuse of the heater.nChecking tire inflation pressureMake sure to check the tire inflatio n pressure frequently. Improper tire inflation pressure can cause poor fuel consumption. Also, as snow tires can cause large amounts of friction, their use on dry roads can lead to poor fuel consumptio n. Use a tire that is appropriate for the season.nLuggageCarrying heavy luggage can lead to poor fuel consumption. Avoid carry -ing unnecessary luggage. Installing a la rge roof rack can also cause poor fuel consumption.nWarming up before drivingSince 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.
