point. Failure to do so could result in damage to
the washer system/reservoir.
!Only use washer fluid which is suitable for
plastic lenses. Improper washer fluid can
damage the plastic lenses of the headlamps.
Warning!G

on hot engine parts, because it may ignite
and burn. You could be seriously burned.

290 Operation
Winter driving
Before the onset of winter, have your
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
“MB Summerfit” to a premixed wind-
shield washer solvent/antifreeze
which is formulated for below freezing
temperatures (
page 397).

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. Mercedes-Benz recom-
mends M+S rated radial-ply tires with a
minimum tread depth of approximately
1/6in (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. Not all M+S rated
tires provide special winter performance.
Make sure the tires you use show 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 and
ESP
® 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.
!A wheel change should only be carried out
at an authorized Mercedes-Benz Center. Other-
wise there is a danger of damaging the vehicle by
jacking it up incorrectly.
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.

adjustment.!Do not replace the LEDs or bulbs yourself.
You could otherwise damage the vehicle lighting
system or parts of the vehicle. Only have the
LEDs or bulbs replaced by an authorized
Mercedes-Benz Center.
iIf the headlamps are fogged up on the inside
as a result of high humidity, driving the vehicle a
distance should clear up the fogging.
iSubstitute bulbs will be brought into use
when lamps malfunction. Observe the messages
in the multifunction display (
page 341).
iIf one of the following bulbs blows, another
bulb will adopt its function:

Rear turn signals

Brake lamps

Side lamps

Tail lamps
