ting started” section.
Rear view mirror
Automatic antiglare rear view mirror
The reflection brightness of the exterior 
rear view mirror on the driver’s side and 
the inside rear view mirror will respond au-
tomatically to glare when
the ignition is switched on, and
incoming light from headlamps falls on 
the sensor in the inside rear view mir-
ror.
The rear view mirror will not react if
reverse gear is engaged
the interior lighting is turned on
the wind screen is installed 
(page 134)
Warning!
G
The automatic antiglare function does not 
react if incoming light is not aimed directly 
at sensors in the inside rear view mirror.
The inside rear view mirror and the exterior 
rear view mirror on the driver’s side do not 
react, for example, if the wind screen is in-
stalled.
Glare can endanger you and others.
Warning!
G
In the case of an accident, liquid electrolyte 
may escape from the mirror housing if the 
mirror glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with 
eyes, skin, clothing, or the respiratory sys-
tem. In case it does, immediately flush af-
fected area with water, and seek medical 
help if necessary.

shoulder before changing lanes.!Electrolyte drops coming into contact 
with the vehicle paint finish can be 
completely removed only while in the 
liquid state by applying plenty of water.

172 OperationEngine compartment
Closing
Let the hood drop from a height of ap-
proximately 1ft (30cm).
The hood will lock audibly.
Check to make sure that the hood is 
fully closed. 
If you can raise the hood at a point 
above the headlamps, then it is not 
properly closed. Open it again and let it 
drop with somewhat greater force.
Engine oil
The amount of oil your engine needs will 
depend on a number of factors, including 
driving style. Higher oil consumption can 
occur when
the vehicle is new
the vehicle is driven frequently at high-
er engine speeds
Engine oil consumption checks should only 
be made after the vehicle break-in period.
Checking engine oil level
When checking the oil level the vehicle 
must
be parked on level ground
be at normal operating temperature
have been stationary for at least five 
minutes with the engine turned off
Warning!
G
If you see flames or smoke coming from the 
engine compartment, or if the coolant tem-
perature gauge indicates that the engine is 
overheated, do not open the hood. Move 
away from vehicle and do not open the hood 
until the engine has cooled. If necessary, 
call the fire department.Warning!
G
The engine is equipped with a transistorized 
ignition system. Because of the high voltage 
it is dangerous to touch any components (ig-
nition coils, spark plug sockets, diagnostic 
socket) of the ignition system
with the engine running
while starting the engine
if ignition is “on” and the engine is 
turned manually
Warning!
G
Be careful that you do not close the hood on 
anyone.

179 Operation
Engine compartment
Windshield washer system and headlamp 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 approx. 7.4 US qt (7 l).
During all seasons, add MB Windshield 
Washer Concentrate “S” 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 wind-
shield washer solvent / antifreeze, de-
pending on ambient temperatures).
Always use washer solvent/antifreeze 
where temperatures may fall below 
freezing. Failure to do so could result in 
damage to the washer system/reser-
voir.More information can be found in the 
“Technical data” section (
page 275).1Washer fluid reservoir
Warning!
G
Washer solvent / antifreeze is highly flam-
mable. Do not spill washer 
solvent / antifreeze on hot engine parts, be-
cause it may ignite. You could be seriously 
burned.iThe windshield washer system on this 
vehicle is heated, so a fluid mixture pro-
duced for temperatures of 
approximately 14°F (-10°C) should be 
sufficient.
!Only use washer fluid which is suitable 
for plastic lenses. Improper washer flu-
id can damage the plastic lenses of the 
headlamps.

183 Operation
Winter driving
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 
“S” to a premixed windshield washer 
solvent / antifreeze which is formulated 
for below freezing temperatures 
(page 275).
Battery test. Battery capacity drops 
with decreasing ambient temperature. 
A well charged battery helps to ensure 
that the engine can be started, even at 
low ambient temperatures.
Tire change. We recommend M+S 
rated radial-ply tires on all four wheels 
for the winter season.
Winter tires
Always use winter tires at temperatures 
below 39°F (4°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, ensure 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 from your tire dealer or 
from any authorized Mercedes-Benz 
Center.Warning!
G
Winter tires with a tread depth under 0.16 in 
(4 mm) must be replaced. They are no long-
er 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.

189 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 engine 
compartment after every engine cleaning. 
Before applying, all control linkage bush-
ings and joints should be lubricated. The 
poly-V-belt and all pulleys should be pro-
tected from any wax. Vehicle washing
Do not use hot water or wash your vehicle 
in direct sunlight. Use only 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 out-
side 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, 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 use only a soft, non-scratchy 
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth 
or sponge.
