WARNING Regularly check the tires for damage. 
Regularly check the tires for damage.
Damaged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle.
Worn, old tires can cause accidents. If the tire tread is worn to minimum tread depth, or if the tires have sustained damage, replace them.

Regularly check the wheels and tires of your vehicle for damage (e.g. cuts, punctures, tears, bulges on tires and deformation or cracks or severe corrosion on wheels) at least once a month, as well as after driving off-road or on rough roads.

Damaged wheels can cause a loss of tire pressure.

Regularly check the tire tread depth and the condition of the tread across the whole width of the tire. If necessary, turn the front wheels to full lock in order to inspect the inner side of the tire surface.

All wheels must have a valve cap to protect the valve against dirt and moisture. Do not mount anything onto the valve (such as tire pressure monitoring systems) other than the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle.

Regularly check the pressure of all the tires including the emergency spare wheel or the spare wheel, particularly prior to long trips, and correct the pressure as necessary.

    Notes on driving
