If special testing equipment is required during a road test, note the following:

• Test and measuring instruments must be secured in the rear seat and operated by a second person from this location.

If test and measuring instruments are operated from the front passenger seat and the vehicle is involved in an accident, there is a possibility that the person sitting in this seat may receive serious injuries when the airbag is triggered.
