Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function while the
engine is running. You should therefore never
turn off the engine while driving. G

Inspect the vehicle underbody and tires/
wheels for possible damage. If the vehicle
