Winter tires
Always use winter tires at temperatures 
below 45°F (7°C) and whenever wintry 
road conditions prevail. Not all M+S rated 
tires provide special winter performance. 
Make sure the tires you use show M+S 
and the mountain/snowflake 
symbol.marking on the tire sidewall. 
These tires meet specific snow traction 
performance requirements of the Rubber 
Manufacturers Association (RMA) and the 
Rubber Association of Canada (RAC) and 
have been designed specifically for use in 
snow conditions. Use of winter tires is the 
only way to achieve the maximum 
effectiveness of the ABS and ESP
® in 
winter operation.
For safe handling, make sure all mounted 
winter tires are of the same make and have 
the same tread design.Always observe the speed rating of the 
winter tires mounted to your vehicle. If the 
maximum speed for which your tires are 
rated is below the speed rating of your ve-
hicle, you must place a notice to this effect 
where it will be seen by the driver. Such no-
tices are available at your tire dealer or any 
authorized Mercedes-Benz Center.
!When scraping ice or snow from the rear 
window, be careful not to damage the sealing 
strip or apertures along the side of the window. 
Warning!G
Winter tires with a tread depth of less than 1/6  in (4 mm) must be replaced. They are 
no longer suitable for winter operation.
