Safety precautions
 
     
Observe following precautions if test and 
measuring instruments are required during a 
road test:  
     
WARNING! 
     
During a road test in an airbag equipped 
vehicle, test equipment must always be 
fastened to and operated from the rear seat 
by a second technician. 
     When driving or riding in an airbag equipped 
vehicle, NEVER hold the scan tool or other 
test equipment in your hands or lap while in 
motion. Objects between you and and the 
airbag increase the risk of injury in an 
accident. 
     
To prevent injuries to persons and/or damage 
to the fuel injection and ignition system, the 
following must be noted: 
     Always switch off the ignition before 
connecting or disconnecting injection or 
ignition system wiring or tester cables.
