Checking coolant level G
WARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following. G
WARNING
The engine cooling system is pressurized, par- ticularly when the engine is warm. When
opening the cap, you could be scalded by hotcoolant spraying out. There is a risk of injury.
Let the engine cool down before opening the
cap. Wear eye and hand protection when
opening the cap. Open the cap slowly half a
turn to allow pressure to escape. X
Park the vehicle on a level surface.
Only check the coolant level when the vehi-
cle is on a level surface and the engine has
cooled down.
X Turn the SmartKey to position 2in the igni-
tion lock (Y page 157).
On vehicles with KEYLESS-GO, press the
Start/Stop button twice (Y page 158).
X Check the coolant temperature display in
the instrument cluster.
The coolant temperature must be below
158 ‡ (70 †).
X Turn the SmartKey to position 0in the igni-
tion lock (Y page 157).
X Slowly turn cap 0043half a turn counter-
clockwise to allow excess pressure to
escape.
X Turn cap 0043further counter-clockwise and
remove it.
If the coolant is at the level of marker bar 0087
in the filler neck when cold, there is enough coolant in coolant expansion tank 0044.
If the coolant level is approximately 0.6 in
(1.5 cm) above marker bar 0087in the filler Engine compartment
333Maintenance and care Z
X
Make sure the vehicle is stationary and the
ignition is switched off.
X Turn the SmartKey to position 2in the igni-
tion lock (Y page 157).
Use the SmartKey instead of the Start/
Stop button on vehicles with KEYLESS-GO.
X Depress and hold the brake pedal.
X Shift the automatic transmission to posi-
tion N.
X Release the brake pedal.
X Release the parking brake.
X Switch off the ignition and leave the Smart-
Key in the ignition lock.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off
wax from the windshield and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind- shield.
Washing by hand In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements in all coun-
tries concerned.
X Do not use hot water and do not wash the
vehicle in direct sunlight.
X Use a soft sponge to clean.
X Use a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.
X Thoroughly hose down the vehicle with a
gentle jet of water.
X Do not point the water jet directly towards
the air inlet.
X Use plenty of water and rinse out the
sponge frequently.
X Rinse the vehicle with clean water and dry
thoroughly with a chamois.
X Do not let the cleaning agent dry on the
paintwork. When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
Power washers G
WARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
! Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information about
the correct distance is available from the
equipment manufacturer.
Move the power washer nozzle around
when cleaning your vehicle.
Do not aim directly at any of the following:
R tires
R door gaps, roof gaps, joints, etc.
R electrical components
R battery
R connectors
R lights
R seals
R trim
R ventilation slots
Damaged seals or electrical components
can lead to leaks or failures.
! If the SmartKey is within the rear detec-
tion range of KEYLESS-GO, the following
situations, for example, could lead to the
unintentional opening of the trunk lid/tail-
gate:
R using a car wash
R using a power washer Care

X All occupants must get out of the vehicle.
Make sure that they are not endangered as
they do so.
X Make sure that no one is near the danger
area while a wheel is being changed. Any-
one who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
X Get out of the vehicle. Pay attention to traf-
fic conditions when doing so.
X Close the driver's door. MOExtended tires (tires with run-flat
properties)
General notes With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tires. The affected
tire must not show any clearly visible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking next to the tire size designation, the load-
bearing capacity and the speed index
(Y page 378). Flat tire

the ground
It is important that you observe the safety
instructions when towing away your vehicle
(Y page 355).
The automatic transmission automatically
shifts to position Pwhen you open the driver's
or front-passenger door or when you remove the SmartKey from the ignition lock. In order
to ensure that the automatic transmission
stays in position Nwhen towing the vehicle,
you must observe the following points:
X Make sure that the vehicle is stationary and
the SmartKey in the ignition lock is in posi- tion 0.
X Turn the SmartKey to position 2in the igni-
tion lock.
On vehicles with KEYLESS-GO, use the
SmartKey instead of the Start/Stop button
(Y page 158).
X Depress and hold the brake pedal.
X Shift the automatic transmission to posi-
tion N.
X Release the brake pedal.
X Release the parking brake.
X Switch on the hazard warning lamps
(Y page 131).
X Leave the SmartKey in position 2in the
ignition lock.
i When towing with the hazard warning
lamps switched on, use the combination
switch as usual to signal a change of direc- tion. In this case, only the indicator lamps
for the direction of travel flash. After reset- ting the combination switch, the hazard
warning lamp starts flashing again. Towing the vehicle with the rear axle
