LIGHTNING Bolt ON

That warning light means the car is in limp mode and it has hindered the throttle operation until the car can be fixed.

You must run the codes to see what's going on, here is a guide

Here is some information from the manual,

This light informs you of a problem with the Electronic Throttle Control system. If a problem is detected the light will come on while the engine is running. Cycle the ignition key when the vehicle is completely stopped and the gear selector is in the PARK position. The light should turn off. If the light remains lit with the engine running your vehicle will usually be drivable, however, see your dealer for service as soon as possible.

If the light is flashing when the engine is running, immediate service is required and you may experience reduced performance, an elevated/rough idle or engine stall and your vehicle may require towing. The light will come on when the ignition is first turned on and remain on briefly as a bulb check. If the light does not during starting, have the system checked by an authorized dealer.

Please let us know what happens.
