Safety notes
WARNING
Work improperly carried out on electronic components and associated software could cause them to cease functioning. Because the vehicle's electronic components are interconnected, any modifications made may produce an undesired effect on other systems. Electronic malfunctions could seriously impair the operating safety of your vehicle.
Contact an authorized Mercedes-Benz Center for repairs or modifications to electronic components.
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 when the engine is running. You should therefore never turn off the engine while driving.
WARNING
Heavy blows against the vehicle underbody or tires/wheels may cause serious damage and impair the operating safety of your vehicle. Such blows can be caused, for example, by running over an obstacle, road debris or a pothole.
If you feel a sudden significant vibration or ride disturbance, or you suspect that damage to your vehicle has occurred:
- turn on your hazard warning flashers.
- slow down carefully.
- drive with caution to an area which is a safe distance from the road.
Inspect the vehicle underbody and tires/ wheels for possible damage. If the vehicle appears unsafe, have it towed to the nearest authorized Mercedes-Benz Center or other qualified maintenance or repair facility for further inspection or repairs.
