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 pre-mixed windshield washer
solvent / antifreeze which is formulated
for temperatures below freezing point
(page 451).
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.

Use a mild car wash detergent, such as
Mercedes-Benz approved Car Sham-
poo, with plenty of water and a
non-scratching cloth to clean sensor
cover1.
!Do not use chrome cleaner on orna-
mental moldings. Although ornamental
moldings may have chrome appear-
ance, they could be made of anodized
aluminum that will be damaged when
cleaned with chrome cleaner. Instead,
use damp cloth to clean those orna-
mental moldings.
Very dirty ornamental moldings of
which you are sure are chrome-plated,
use a chrome cleaner. If in doubt
whether an ornamental molding is
chrome-plated, contact an authorized
Mercedes-Benz Center.
!Only use window cleaning solutions
that are suitable for plastic lamp lens-
es. Window cleaning solutions which
are not suitable may damage the plas-
tic lamp lenses of the headlamps.
Therefore, do not use abrasives, sol-
vents or cleaners that contain solvents.
Never apply strong force and only use a
soft, non-scratching cloth when clean-
ing the lenses. Do not attempt to wipe
dirty lenses with a dry cloth or sponge.
Otherwise you may scratch or damage
the lens surface.

Bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See an authorized
Mercedes-Benz Center for headlamp ad-
justment.
iIf the headlamps or front fog lamps are
fogged up on the inside as a result of
high humidity, driving the vehicle a dis-
tance with the lights on should clear up
the fogging.
iSubstitute bulbs will be brought into
use when the following lamps malfunc-
tion:
Turn signal lamps
Brake lamps
Parking lamps
Tail lamps
Observe the messages in the multi-
function display (

Notes on bulb replacement
Only use 12-volt bulbs of the same type
and with the specified watt rating.
Switch the lights off before changing a
bulb to prevent short circuits.
Always use a clean lint-free cloth when
handling bulbs.
Your hands should be dry and free of oil
and grease.
If the newly installed bulb does not
come on, visit an authorized
Mercedes-Benz Center.Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center:
the additional turn signals in the exteri-
or rear view mirrors
the high mounted brake lamp
the brake lamps
the parking lamps and the side marker
lamps in the tail lamp unit
the rear fog lamps
the low beam (Xenon or Bi-Xenon*)
lamps
the front fog lamps
the front side marker lamps
Warning!
G
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you:
touch or move it when hot
drop the bulb
scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.
iHave the headlamp adjustment
checked regularly.
