MSolutions The transmission has
problems shifting gear. The transmission is losing oil.
X
Have the transmission checked at a qualified specialist
workshop immediately. The acceleration ability
is deteriorating.
The transmission no
longer changes gear. The transmission is in emergency mode.
It is only possible to shift into
secondgear and reverse gear.
X Stop the vehicle.
X Shift the transmission to position P.
X Switch off the engine.
X Wait at least ten seconds before restarting the engine.
X Shift the transmission to position Dor R.
If D is selected, the transmission shifts into secondgear; ifRis
selected, the transmission shifts into reverse gear.
X Have the transmission checked at a qualified specialist
workshop, e.g. an authorized Mercedes-Benz Center,
immediately. Releasing the parking lock manually
! Do not use any sharp-edged objects to
remove the selector lever gaiter from the
center console. This could damage the
selector lever gaiter. X
Apply the electric parking brake.
X Press the frame of selector level gaiter :
together somewhat on the side edge at the
back and hold with one hand ;.
X With the other hand, pry off the frame of
selector level gaiter :with a flat, blunt
object (e.g. a screwdriver wrapped in cloth) at rear edge
=, pulling it up and out at the
same time.
X Press release button ?down and
simultaneously move the selector lever out
of position P.
The selector lever can now be moved freely
until it is returned to position P.
In the event of an electrical malfunction, it is
possible to release the selector lever lock
manually to move it out of position P. This is
the case, for example, if you wish to tow the
vehicle away. Refueling

Notes on the oil level Depending on the driving style, the vehicle
consumes up to 0.9 US qt
(0.8l) of oil over a
distance of 600 miles (1000km). The oil
consumption may be higher than this when
the vehicle is new or if you frequently drive at
high engine speeds.
AMG vehicles: before operation on race
tracks, check the oil level and (Y page 275)
add oil if necessary (Y page 276). Race track
operation is only permitted with a maximum
engine oil level.
Depending on the engine, the oil dipstick may
be in a different location.
When checking the oil level:
R park the vehicle on a level surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
R if the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly: wait about 30 minutes
before carrying out the measurement.
Checking the oil level using the oil
dipstick G
WARNING
Certain components in the engine
compartment, 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. Engine compartment
275Maintenance and care Z

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 275).

Checking coolant level G
WARNING
Certain components in the engine
compartment, 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,
particularly when the engine is warm. When
opening the cap, you could be scalded by hot
coolant 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. Example X
Park the vehicle on a level surface.
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 2in the
ignition lock (Y page 139).
On vehicles with KEYLESS-GO, press the
Start/Stop button twice (Y page 139).
X Check the coolant temperature gauge in
the multifunction display.
The coolant temperature must be below
158 ‡ (70 †).
X Turn the SmartKey to position
0(Y page 139) in the ignition lock.
X Slowly turn cap ;half a turn counter-
clockwise to 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 level is approximately 0.6 in
(1.5 cm) above marker bar =in the fuel
filler neck when warm, there is enough
coolant in expansion tank :.
X If necessary, add coolant that has been
tested and approved by Mercedes-Benz.
X Replace cap ;and turn it clockwise as far
as it will go.
For further information on coolant, see
(Y page 347).
