1. A computer comprising a processor and a memory storing instructions executable by the processor to:
- upon determining that a vehicle entered an autonomous-steering mode, deactivate a plurality of lights on a steering-wheel rim;
upon determining that the vehicle is in the autonomous-steering mode, instruct an actuator rotatably coupled to the steering-wheel rim to hold the steering-wheel rim stationary while turning road wheels of the vehicle to create a current steering angle of the road wheels; and
upon initiating a transition of the vehicle from the autonomous-steering mode to a manual-steering mode, illuminate at least one of the lights, wherein a position of the illuminated lights indicates a steering-wheel angle, wherein the steering-wheel angle correspond s to the current steering angle of the road wheels of the vehicle by a steering ratio.

Abstract
A computer is programmed to, upon determining that a vehicle entered an autonomous-steering mode, deactivate a plurality of lights on a steering-wheel rim; and upon initiating a transition of the vehicle from the autonomous-steering mode to a manual-steering mode, illuminate at least one of the lights that is at a steering-wheel angle corresponding to a current steering angle of the vehicle.

8. A method, comprising:
-
upon determining that a vehicle entered an autonomous-steering mode, deactivating, by a computer of the vehicle, a plurality of lights on a steering-wheel rim; upon determining that the vehicle is in the autonomous-steering mode, instructing, by the computer, an actuator rotatably coupled to the steering-wheel rim to hold the steering-wheel rim stationary while turning road wheels of the vehicle to create a current steering angle of the road wheels; and upon initiating a transition of the vehicle from the autonomous-steering mode to a manual-steering mode, illuminating at least one of the lights, wherein a position of the illuminated lights indicates a steering-wheel angle, wherein the steering-wheel angle corresponds to the current steering angle of the road wheels of the vehicle by a steering ratio. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A vehicle, comprising:
-
a steering-wheel rim; a plurality of lights on the steering-wheel rim; an actuator rotatably coupled to the steering-wheel rim; and a computer in communication with the plurality of lights and the actuator, the computer programmed to, upon determining that the vehicle entered an autonomous-steering mode, deactivate the plurality of lights; upon determining that the vehicle is in the autonomous-steering mode, instruct the actuator to hold the steering-wheel rim stationary while turning road wheels of the vehicle to create a current steering angle of the road wheels; and upon initiating a transition of the vehicle from the autonomous-steering mode to a manual-steering mode, illuminate at least one of the lights, wherein a position of the illuminated lights indicates a steering-wheel angle, wherein the steering-wheel angle corresponds to the current steering angle of the road wheels of the vehicle by a steering ratio. - View Dependent Claims (16, 17)
