Windshield washer system and head-lamp cleaning system
Fluid for the windshield washer system and
the headlamp cleaning system is supplied
from the windshield washer reservoir. It
has a capacity of approximately
7.4 US qt (7.0 l).
During all seasons, add MB Windshield
Washer Concentrate “MB SummerFit” to
water. Premix the windshield washer fluid
in a suitable container.
Refill the reservoir with MB Windshield
Washer Concentrate and water (or
commercially available premixed
windshield washer solvent/antifreeze,
depending on ambient temperatures).The washer fluid reservoir is located in the
trunk underneath the interior floor on the
left-hand side.
1Interior floor

3Removing interior floor
!
Always use washer solvent/antifreeze
where temperatures may fall below freezing
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.
Do not use distilled or deionized water in the
washer fluid reservoir. Otherwise, the washer
fluid level sensor could be damaged.
Warning!
G
Washer solvent/antifreeze is highly flamma-
ble. Do not spill washer solvent/antifreeze
on hot engine parts, because it may ignite
and burn. You could be seriously burned.

292 OperationWinter drivingBefore 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 401).


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.
After you have fitted the winter tires,
restart the TPMS (
page 274).
!
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, in par-
ticular because they do not provide suffi-
cient grip. This could cause you to lose
control of your vehicle and cause an acci-
dent.

300 OperationVehicle careCleaning the headlamps
Wipe the headlamp lens with a damp
sponge.Cleaning the headlamps

Wipe the headlamp lens with a damp
sponge.
Soft top care
Frequent cleaning reduces the dirt-repel-
lent effect of the soft top.
Intensive cleaning with Mercedes-Benz
care products for soft tops can help to re-
store the dirt-repellent effect.
!
Fold the windshield wiper arms back onto
the windshield before turning the SmartKey in
the starter switch.
Hold on to the wiper when folding the wiper arm
back. If released, the force of the impact from
the tensioning spring could crack the windshield.
!
Only use windshield washer fluid suitable
for plastic lamp lenses. Unsuitable windshield
washer fluid may cause damage to the plastic
lenses of the headlamps.
Do not use


a dry cloth


abrasive products


solvents


cleaning agents containing solvents
You could otherwise scratch or damage the lens
surface.

Incorrect cleaning and care can damage the
soft top or cause leaks. In this case contact an

soft top inspected.
!
Remove bird droppings immediately. Bird
droppings are caustic and can cause leaks in the
soft top. Do not remove ice and snow with
sharp-edged devices.
