Driving tips Hybrid vehicle driving tips For economical and ecological driving, pay attention to the following points: ◆ Using Eco drive mode When using Eco drive mode, the torque corresponding to the accelerator pedal depression amount can be generated more smoothly than it is in normal conditions.
Page 388 4-6. Driving tips ◆ Delays Repeated acceleration and deceleration, as well as long waits at traffic lights, will lead to bad fuel economy. Check traffic reports before leaving and avoid delays as much as possible. When driving in a traffic jam, gently release the brake pedal to allow the vehicle to move forward slightly while avoiding over- use of the accelerator pedal.
Page 389 4-6. Driving tips ◆ 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. ◆ Warming up before driving Since the gasoline engine starts up and cuts out automatically when cold, warming up the engine is unnecessary.
