! DEF
is not a fuel additive and must not be
added to the fuel tank. If DEF is added to
the fuel tank, this can lead to engine
damage.
i If you are adding between maintenance
intervals, add approximately 1 gallon (3.8 l)
of DEF to the DEF tank. One gallon (3.8 l)
of DEF is approximately 2 DEF refill bottles.
Then, have the DEF supply checked and
filled completely if necessary. For this
purpose, Mercedes-Benz recommends a
qualified specialist workshop.
Further information on DEF (Y page 527).
The filler neck for DEF is located under the
"Minispare" emergency spare wheel in the

Important safety notes
G
WARNING
Do not park this vehicle in areas where
combustible
materials can come into contact
with the hot exhaust system. Combustible
materials, such as grass, hay or leaves could
be ignited by the hot exhaust system and
cause a vehicle fire. Do not park the vehicle
on dry grassland or harvested grain fields.
Unintended vehicle movement can cause
serious personal injury or damage to the
vehicle or the vehicle drivetrain. To reduce
such risks, always do the following before
turning off the engine and leaving the vehicle:
R keep your right foot on the brake pedal.
R engage the electric parking brake.
R shift the automatic transmission into park
position P.
R slowly release the brake pedal.
R when parked on an incline, always turn the
front wheels towards the road curb.
R turn the SmartKey in the ignition lock to
position 0 and remove the SmartKey from
the ignition lock, or press the KEYLESS-GO
Start/Stop button.
R take the SmartKey with you and lock the
vehicle when leaving. Switching off the engine
Important safety notes G
WARNING
Do not turn off the engine before the vehicle
has
come to a complete stop. With the engine
not running, there is no power assistance for
the brake and steering systems. In this case,
it is important to keep in mind that a
considerably higher degree of effort is
necessary to brake and steer the vehicle. Parking

Fogged up or dirty windshield If the windshield in front of the camera is
fogged
up or dirty on the inside or outside, the
Night View Assist Plus display is affected. G
WARNING
Please do not forget that your primary
responsibility
is to drive the vehicle. A driver's
attention to the road must always be his/her
primary focus when driving. For your safety
and the safety of others, stop before trying to
remove window fogging or cleaning the
windshield in front of the Night View Assist
Plus camera.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
X To defrost: check the automatic air
conditioning
settings (Y page 296) and fold
down the camera cover (Y page 467).

Vehicles with oil level measurement
function

in the on-board computer: observe
the information in the on-board computer
when doing so. Vehicles with oil dipstick: if
the oil level is at or below the MIN mark on
the oil dipstick,
add 0.55 to 1.1 US qt (0.5 to 1.0 l) engine
oil.
X Replace cap : on the filler neck and turn
clockwise.
Ensure that the cap locks into place
securely.
X Check the oil level again with the oil
dipstick (Y page 458) or the on-board
computer (Y page 458).
Further information on engine oil
(Y page 527). Checking and adding other service
products
Checking the coolant level Only check the coolant level when the vehicle
is

on a level surface and the engine has cooled
down.
X Turn the SmartKey to position
2 (Y page 303) in the ignition lock.
On vehicles with KEYLESS-GO, press the
Start/Stop button twice

(Y page 303).
X Check the coolant temperature display in
the instrument cluster.
The coolant temperature must be below
158 ‡

(70 †). G
WARNING
In order to avoid any potentially serious burns:
R use extreme caution when opening the
hood if there are any signs of steam or
coolant

leaking from the cooling system, or if the coolant temperature display indicates
that the coolant is overheated.
R do not remove the pressure cap on the
coolant

reservoir if the coolant temperature
is above 158 ‡ (70 †). Allow the engine to
cool down before removing the cap. The
coolant reservoir contains hot fluid and is
under pressure.
R using a rag, slowly turn the cap
approximately 1
/ 2 turn to relieve excess
pressure. If opened immediately, scalding
hot fluid and steam will be blown out under
pressure.
R do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts. X
Slowly turn cap : half a turn counter-
clockwise and allow excess pressure to
escape.
X Turn cap :
further counter-clockwise and
remove it.
If the coolant is at the level of marker bar
= in the filler neck when cold, there is
enough coolant in coolant expansion
tank ;.
If the coolant is approximately 0.6 in
(1.5 cm) above marker bar = in the filler
neck when warm, there is enough coolant
in coolant expansion tank ;.460

Windshield washer system and
headlamp cleaning system The washer fluid reservoir is used for both the
windshield

washer system and the headlamp
cleaning system.
i Vehicle components and their service
products must match. You should,
therefore, only use products that have been
tested and approved by Mercedes-Benz.
Information on tested and approved
products can be obtained at any authorized
Mercedes-Benz Center or on the Internet at
http://www.mbusa.com (USA only).G
WARNING
Washer solvent/antifreeze is highly
flammable. Do not spill washer solvent/
antifreeze

on hot engine parts, because it may
ignite and burn. You could be seriously
burned.
! At temperatures below freezing: always
fill the washer fluid reservoir with a mix of
water and windshield washer concentrate
(e.g. MB WinterFit). There is otherwise a
risk of damaging the windshield washer
system/headlamp cleaning system.
! Only use washer fluid concentrate which
is suitable for plastic lenses. Unsuitable
washer fluid concentrate could damage the
plastic lenses of the headlamps.
! Do not add distilled or de-ionized water to
the washer fluid container. Otherwise, the
level sensor may be damaged.
i Add windshield washer concentrate, e.g.
MB SummerFit, to the washer fluid all year
round. Example: washer fluid reservoir
X
Mix the windshield washer fluid in a
container beforehand.
X At temperatures above freezing: fill the
washer fluid reservoir with a mix of water
and windshield washer concentrate (e.g.
MB SummerFit).
X At temperatures below freezing: fill the
washer fluid reservoir with a mix of water
and windshield washer concentrate (e.g.
MB

WinterFit). Adapt the mixing ratio to the
outside temperature. For information on
the mixing ratio (Y page 529).
X To open: pull cap : upwards by the tab.
X Add the premixed washer fluid.
X To close:
press cap : onto the filler neck
until it engages.
Brake fluid level !
If you notice that the brake fluid level in
the brake fluid reservoir has fallen to the
MIN mark or less, check the brake system
immediately for leaks. Also check the
thickness of the brake linings. Contact a
qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center
immediately.
Do not add brake fluid. This does not
correct the error.
Only check the brake fluid level when the
vehicle is stationary and on a level surface. Engine compartment
