Before the onset of winter, have your vehi-
cle winterized at an authorized
Mercedes-Benz Center. This service in-
cludes:
ț Check of anticorrosion and antifreeze
concentration.
ț 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
(
୴ page 437).
ț Battery test. Battery capacity drops
with decreasing ambient temperature.
A well charged battery helps to ensure
that the engine can be started and the
SBC brake system will be fully opera-
tional even at low ambient tempera-
tures.
ț Tire change. Mercedes-Benz recom-
mends M+S rated radial-ply tires with a
minimum tread depth of approximately
1
/
6
in (4 mm) on all four wheels for the
winter season.
Winter tires
Always use winter tires at temperatures
below 45°F (7°C) and whenever wintry
road conditions prevail. Use of winter tires
is the only way to achieve the maximum ef-
fectiveness of the ABS and ESP in winter
operation.
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.
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.
