The flashing bolt is the issue. You need a mobile auto electrician with a pro grade scan tool computer.

The lightning bolt warning light alerts you to a fault in the electronic throttle control system in your vehicle. This may be a faulty throttle body, the throttle body sensor or possibly the throttle body control motor which is what controls the opening and closing of the throttle body as the motor requires more fuel.

you might need a fuel pump relay under dash 10 min fix/and your d4 flashing light bad transmission.

Is the key in working order? does the light flash faster when the ignition is on?

try starter or your ignition relay switch or check fuses

If your check engine light starts to flash that is telling you to shut it down so that you do not do any significant damage to the engine. I would recommend that you go to your local parts store or call a mobile tech out to read what codes are possibly stored in your cars computer and find out what is going on.
