CEL 'ON' and turns 'OFF' after ignition

thanks. Let me elaborate my question. When I turn on the key, all indication lights are ON and after 2 seconds all are off except CEL. When I start the engine, CEL turns OFF. Is this the normal operation of car?

Yes that is normal...... However if it comes on while the engine is 'running' then it time to have it tested to find out what the fault codes are... Keep in mind the Check Engine Light doesn't mean the car is going to blow up, it simply means the on board computer has seen a malfunction in the operating system and is just making the operator aware of it...no urgency but needs to be checked... The RED lights are the ones to be concerned with if they come on with engine running!!.. See owners manual for more details!

thanks a lot

Sure
