Which engine oil you are using?

Vibration while the engine is cold is normal.
Don't move the vehicle till the blue temp light goes off.

Once the blue temp light goes off and the engines is still vibration then it needs to be checked. At this point the RPM should be ~700. If its below 700 or greater than 800 then get the car tuned.

Blue light doesn't mean that the vehicle should not be moved. Infact letting the car idle more for is bad.

Ask the dealer ship to check the valve lashes, fuel filter and also the air filter.
