Winter driving
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 premixed
windshield washer solvent / antifreeze
which is formulated for temperatures
below freezing point (
page 467).
Battery test
Battery capacity drops with decreasing
ambient temperature. A well charged
battery helps to make sure that the en-
gine can be started and the SBC brake
system will be fully operational, even at
low ambient temperatures.
Tire change
Mercedes-Benz recommends M+S rat-
ed radial-ply tires with a minimum tread
depth of approximately
1/6 in (4 mm)
on all four wheels for the winter sea-
son.
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, 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 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.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.
Warning!
G
If you use your spare tire when winter tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may
very well impair turning stability and that
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized
Mercedes-Benz Center.
342 OperationWinter drivingBlock heater* (Canada only)
The engine is equipped with a block heat-
er.
The electrical cable may be installed at an
authorized Mercedes-Benz Center.Snow chains
Snow chains should only be driven on
snow-covered roads at speeds not to ex-
ceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.Please observe the following guidelines
when using snow chains:
Use of snow chains is not permissible
with all wheel/tire combinations.
Snow chains should only be used on
the rear wheels. Follow the manufac-
turer's mounting instructions.
Only use snow chains that are ap-
proved by Mercedes-Benz. Your autho-
rized Mercedes-Benz Center will be
glad to advise you on this subject.
Use of snow chains may be prohibited
depending on location. Always check
local and state laws before installing
snow chains.
!When driving with snow chains, always
select the raised level of the level con-
trol system Airmatic* (
page 248).
Other settings may result in damage to
your vehicle.
iWhen driving with snow chains, you
may wish to deactivate the ESP
(page 89) before setting the vehicle
in motion. This will improve the vehi-
cle’s traction.
!Even on vehicles with all-wheel-drive,
use snow chains on rear tires only.
Use of snow chains is not permissible
with tire sizes:
265/35 ZR18

We strongly recommend that you have
your vehicle serviced by an authorized
Mercedes-Benz Center, in accordance with
the Maintenance Booklet at the times
called for by the maintenance service indi-
cator display.
Failure to have the vehicle maintained in
accordance with the Maintenance Booklet
and maintenance service indicator at the
designated times /mileage will result in ve-
hicle damage not covered by the
Mercedes-Benz Limited Warranty.
The maintenance service indicator will no-
tify you when your next maintenance ser-
vice is due.
Starting approximately one month before
maintenance service is due, one of the fol-
lowing messages will appear in the multi-
function display while you are driving or
when you switch on the ignition (example
service A):
Service A in XXXX miles (km)
Service A in XX days
Service A in X day
Service A due now!The maintenance services will be indicated
by showing a service type A through type H
in the multifunction display. Types A
through H are classified based on estimat-
ed time needed to perform the mainte-
nance service, ranging:
from
Service A(approx. one hour)
toService H(approx. eight hours)When the service type appears, you can
use the vehicle’s control system to view a
list of the service items (1-14) that need to
be performed at the called for service type
(
page 347).iThe additional + after the type of ser-
vice indicates the degree of wear of the
brake pads.
The brake pads may reach their wear
limit in the time period up to the next
service interval.
Have the brake pads checked and, if
necessary, replaced by an authorized
Mercedes-Benz Center during your
next service appointment.
