Instruments and controls Operation Driving Instrument cluster display Practical hints Car care Technical data Index Driving instructions Tires Warning! If you feel a sudden significant vibration or ride disturbance, or you suspect that possible damage to your vehicle has occurred, you should turn on the hazard warning flashers, carefully slow down, and drive with caution to an area which is a safe distance from the roadway. Inspect the tires and under the vehicle for possible damage. If the vehicle or tires appear unsafe, have it towed to the nearest Mercedes-Benz Center or tire dealer for repairs. Tread wear indicators (TWI) are required by law. These indicators are located in six places on the tread circumference and become visible at a tread depth of approximately 1/16 in (1.5 mm), at which point the tire is considered worn and should be replaced. The tread wear indicator appears as a solid band across the tread. 206 Warning! Do not allow your tires to wear down too far. As tread depth approaches 1/16 in (1.5 mm), the adhesion properties on a wet road are sharply reduced. Depending upon the weather and/or road surface (conditions), the tire traction varies widely.
