There are a few things you can do to keep your hybrid in EV mode as much as possible. First, try to drive at a constant speed. This will help the car's battery to last longer and allow you to stay in EV mode for a longer period of time. Second, avoid stop-and-go traffic whenever possible. This type of driving drains the battery quickly and doesn't allow the car to recharge properly. Finally, use the regenerative braking feature as much as possible. This helps to recharge the battery while you're driving and can extend the amount of time you can stay in EV mode.
