Operation
Winter driving
Before the onset of winter, have your vehi-
cle winterized at an authorized 
Mercedes-Benz Center. This service in-
cludes:
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 pre-mixed windshield washer 
solvent/antifreeze which is formulated 
for temperatures below freezing point 
(
Battery test. Battery capacity drops 
with decreasing ambient temperature. 
A well charged battery helps to ensure 
that the engine can be started and the 
electro-hydraulic brake system will be 
fully operational 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 sym-
bol
.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 effec-
tiveness of the ABS and ESP
®
 in winter op-
eration.
For safe handling, make sure all winter 
tires mounted are of the same make and 
have the same tread design. 
!
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.
