Turning the ignition key to MAR the warning light on the dial turns on, but it should go off after few seconds.
If the warning light stays on (on certain versions together with the message on the display), you will not have steering assistance and the effort on the steering wheel will be increased, steering is however possible. Contact Fiat Dealership.
