Either the camera or radar are damaged,
covered, or obstructed (e.g. by mud, ice,
snow, etc.)

If damage to the windshield occurs, have
the windshield replaced by an authorized

WARNING!
To prevent serious injury or death:
Always remain alert and be ready to take
control of the car in the event that the TJA
system disables.
Always keep your hands on the steering
wheel when the TJA system is activated.
Maintain a safe distance from other vehi-

attention to their surroundings when the
system is operating and be ready to take
control of the vehicle at any time.
Do not place any objects on the steering
wheel (e.g. steering wheel covers) which
could interfere with the hand detection
sensor on the steering wheel.
