vehicle winterized at an authorized 
Mercedes-Benz Center. This service 
includes:
Check of anticorrosion and antifreeze 
concentration.
Addition of cleaning concentrate to the 
water of the windshield and headlamp 
cleaning system. Add MB Concentrate 
“S” to a premixed windshield washer 
solvent/antifreeze which is formulated 
for below freezing temperatures 
(page 448).
Battery test. Battery capacity drops 
with decreasing ambient temperature. 
A well charged battery helps to make 
sure that the engine can be started, 
even at low ambient temperatures.
Tire change.
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.marking on 
the tire sidewall. These tires meet specific 
snow traction performance requirements 
of the Rubber Manufacturers Association 
(RMA) and the Rubber Association of Can-
ada (RAC) and have been designed specif-
ically for use in snow conditions. Use of 
winter tires is the only way to achieve the 
maximum effectiveness of the ABS, ESP
®, 
and 4MATIC in winter operation. 
For safe handling, make sure that all 
mounted winter tires are of the same make 
and have the same tread design.Always observe the speed rating of the 
winter tires installed on your vehicle. If the 
maximum speed for which your tires are 
rated is below the speed rating of your 
vehicle, you must place a notice to this 
effect where it will be seen by the driver. 
Such notices are available from your tire 
dealer or from any authorized 
Mercedes-Benz Center.
Warning!
G
Winter tires with a tread depth of less than 1/6in (4 mm) must be replaced. They are no 
longer suitable for winter operation.
