If testing equipment must be used during a road test, observe the
following:
WARNING
Distraction and testing equipment that is not secured properly
can cause accidents.
The passenger airbag could pose a risk if it deploys in a colli‐
sion.
• Operating testing equipment while driving is a distraction.
• Testing equipment that is not secured properly increases
the risk of injury.
♦ Always secure testers on the rear seat with a strap and
have a second person on the rear seat operate them.
1.3 Safety Precautions, Vehicles with Start/
Stop System

There is a risk of injury if the engine starts automatically in ve‐
hicles with the Start/Stop System.
♦ For vehicles with an activated Start/Stop System (recog‐
nizable from a notification in the instrument cluster), the
motor can be started automatically if needed.
♦ Make sure that the start/stop system is deactivated when
working on the vehicle (turn off the ignition, turn on the
ignition when necessary).
