In our cars, the engine is started using the start/stop button.
In our vans, the engine is started using the ignition key. You will find the key in the glove compartment.
If the vehicle isn't starting, it might be because the brakes are not applied firmly enough.
Another reason could be the steering wheel lock. This is often the case for our vans which are started using an ignition key. Turn the key in the lock while pulling the steering wheel left and right.
