309 Operation
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 437).
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.
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. 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 1/6in (4 mm) must be replaced. They are no 
longer suitable for winter operation.

317 Operation
Vehicle care
Engine cleaning 
Prior to cleaning the engine compartment, 
make sure to protect electrical compo-
nents and connectors from contact with 
water and cleaning agents.
Corrosion protection, such as MB Anticor-
rosion Wax, should be applied to the en-
gine compartment after every engine 
cleaning. Before applying, all control link-
age bushings and joints should be lubricat-
ed. The poly-V-belt and all pulleys should 
be protected from any wax.
Vehicle washing
Do not use hot water or wash your vehicle 
in direct sunlight. Only use a mild car wash 
detergent, such as Mercedes-Benz ap-
proved Car Shampoo.
Thoroughly spray the vehicle with a dif-
fused jet of water. Direct only a very weak 
spray towards the ventilation intake. Use 
plenty of water and rinse the sponge and 
chamois frequently.Rinse with clear water and thoroughly dry 
with a chamois. Do not allow cleaning 
agents to dry on the finish.
Due to the width of the vehicle, fold in ex-
terior rear view mirrors prior to running the 
vehicle through an automatic car wash to 
prevent damage to the mirrors. 
In the winter, thoroughly remove all traces 
of road salt as soon as possible.
When washing the underbody, do not for-
get to clean the inner sides of the wheels.Ornamental moldings
For regular cleaning and care of very dirty 
chrome-plated parts, use a chrome clean-
er.
Headlamps, side markers, tail lamps, 
turn signal lenses
Use a mild car wash detergent, such as 
Mercedes-Benz approved Car Shampoo, 
with plenty of water.
To prevent scratches, never apply strong 
force and only use a soft, non-scratchy 
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth 
or sponge.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of 
water, and a SmartKey with 
KEYLESS-GO* is in close proximity, i.e. 
within approximately 3 ft (1 m), the ve-
hicle could be inadvertently locked or 
unlocked.

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.
iBackup lamps will be brought into use 
when the following lamps malfunction:
Turn signal lamps
Brake lamps
Parking lamps

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
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.
