CAR STATUS & ALERTS • Check fuel level, tire pressure, engine oil life, odometer and temperature at a glance. • Get alerts before it's too late, like a low-fuel warning. DRIVING MODE DASHBOARD • Turn your phone into a car dashboard with big buttons for maps, calls, radio and weather. • Stay focused on the road while you navigate. FIND MY CAR & SERVICE • See your car's location on the map with GPS and get back to it fast. • Find official dealerships and service centers nearby in seconds. 35+ CAR BRANDS Ford, Toyota, Kia, Hyundai, BMW, Audi, Mercedes, Tesla, Honda, Nissan, and more (full list in the app).
