Applicability:
Systems which provide information not directly related to the immediate driving situation. (Compare exceptions
under explanation)
Verification/Applicable methods:
Inspection, whether the driver can interact with the system at his own pace, i.e. can he decide when to provide an
input and how long information is displayed?
Result = Yes/No
References:
No additional references.

System controls should be designed such that they can be operated without adverse impact on the primary driving controls.
Explanation:
This principle addresses the relationship between the primary driving controls and the system controls in order to
avoid an unintended interference of operation. This means that the location, kinematics, control forces and control
travel of a system control should be designed such that its operation does neither hinder an intended nor facilitate
an unintended primary control input.
Examples:
Good: The most frequently used controls of the system are located within fingertip reach from the steering wheel
rim.
Bad: A rotary control with concentric axis on the steering wheel, which requires a momentum for operation that
may also induce a change in steering angle.
Applicability:
All systems intended to be used while driving, especially nomadic devices and aftermarket systems.
Verification/Applicable methods:
Verification by inspection whether system operation interferes with operation of primary driving controls resulting
in an unintended effect on vehicle motion.
Result = Yes/No.

The driver should have control of the loudness of auditory information where there is likelihood of distraction.
Explanation:
To have control of auditory information means that the driver can adjust the volume and mute the sound to a
virtually unperceivable level.
