Since is 1 year old go to the insurance office, renew the insurance. Use the same insurance company that you used when buying the car.

Then go to the Traffic dept. Kiosk in City Center basement, ask for Car registration renewal, they will ask for ID, car registration, and insurance. If you hve any pendng traffic violation they will probably ask for settlement before issuing new registration. Also you can go to the Madinat Khalifa Traffic Dept for renewal. But remember insurance is a must!!

Pay 100 QAR and then you are set.
