Problems with the transmission
Problem
Possible causes/consequences and
M
MSolutions The transmission has
problems shifting gear. The transmission is losing oil.
X Have the transmission checked at a qualified specialist work-
shop 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.
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 work-
shop immediately. Problems with hybrid operation (Y
page 282).Transfer case
This section only applies to vehicles with all-
wheel drive (4MATIC). The front and rear
axles are constantly driven.
! Performance tests may only be carried
out on a two-axle roller dynamometer. Oth-
erwise, the braking system or the transfer
case could be damaged. Contact a qualified
specialist workshop for more information
on performance tests.
! Since ESP ®
engages automatically, the
ignition must be switched off (the key or
Start/Stop button must be in position 0or
1) if:
R the electric parking brake is being tested
using a brake dynamometer.
R the vehicle is being towed with only one
axle raised (not permitted for vehicles
with 4MATIC).
The brake system could otherwise be dam-
aged. !
Vehicles with 4MATIC must not be towed
with the front or rear axle raised; otherwise,
the transmission may be damaged. Refuelling
Important safety notes
G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refuelling. G
WARNING
Fuels are poisonous and hazardous to health. There is a danger of injury.
Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel 200

nose and throat. You may also experience
coughing and watery eyes.
Do not inhale any ammonia vapours that may
be released. Only fill the AdBlue ®
tank in well-
ventilated areas.
Do not swallow AdBlue ®
or let it come into
contact with skin, eyes or clothing. Keep
AdBlue ®
away from children.
If you or others come into contact with
AdBlue ®
, observe the following:
R immediately rinse AdBlue ®
off your skin
with soap and water.
R if AdBlue ®
comes into contact with your
eyes, immediately rinse them thoroughly
with clean water. Seek medical attention
immediately.
R if AdBlue ®
is swallowed, immediately rinse
your mouth out thoroughly. Drink plenty of
water. Seek medical attention immedi-
ately.
R change immediately out of clothing that
has come into contact with AdBlue ®
.
! Only use AdBlue ®
in accordance with
ISO 22241. Do not mix any additives with
AdBlue ®
, and do not dilute AdBlue ®
with
water. This may destroy the BlueTEC
exhaust gas aftertreatment system.
! In order to fill the AdBlue ®
tank, the vehi-
cle must be parked on a level surface. The
AdBlue ®
tank can only be filled as intended
with the vehicle parked on a level surface.
Fluctuations in capacity will thus be avoi-
ded. Filling a vehicle standing on an uneven
surface is not permitted. There is a danger of overfilling, which can cause damage to
BlueTEC exhaust gas aftertreatment com-
ponents.
! Surfaces which have come into contact
with AdBlue ®
while refilling should be
rinsed immediately with water, or remove
AdBlue ®
with a moist cloth and cold water.
If AdBlue ®
has already crystallised, use a
sponge and cold water to clean the area. AdBlue
®
residue crystallises after a certain
amount of time and soils the affected sur-
faces.
! AdBlue ®
is not a fuel additive and must
not be added to the fuel tank. If AdBlue ®
is
added to the fuel tank, this can lead to
engine damage.
Have the AdBlue ®
tank refilled at a qualified
specialist workshop. However, you can also
top up the AdBlue ®
tank:
R at a filling station with an AdBlue ®
filling
pump
R with AdBlue ®
refill bottles
R with an AdBlue ®
refill canister
When the pump nozzle switches off automat-
ically during filling at a filling pump, the
AdBlue ®
tank has been completely filled. Do
not fill the AdBlue ®
tank any further. AdBlue ®
may leak out.
To avoid transporting already opened refill
containers in the vehicle, completely empty
refill bottles or canisters when filling the
AdBlue ®
tank, if possible.

Closing the bonnet
X
Lower the bonnet and let it fall from a
height of approximately 20 cm.
X Check that the bonnet has engaged prop-
erly.
If the bonnet can be raised slightly, it is not
properly engaged. Open it again and close
it with a little more force. Radiator
Do not cover up the radiator. Do not use ther-
mal mats, insect protection covers or any-
thing similar. Doing so can cause the Onboard Diagnostics System to display inaccurate val-
ues. Some of these values are legally required
and must always be correct. Engine oil
General notes Depending on your driving style, the vehicle
consumes up to 0.8 litres of oil per 1,000 km.
The oil consumption may be higher than this
when the vehicle is new or if you frequently
drive at high engine speeds.
Depending on the engine, the oil dipstick may be installed at 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 approximately
30 minutes before carrying out the meas-
urement. Checking the oil level using the oil dip-
stick G
WARNING
Certain components in the engine compart-
ment could be very hot, e.g. the engine, the
radiator and parts of the exhaust system.
There is a risk of injury when accessing the
engine compartment.
As far as possible, allow the engine to cool
down and only touch the components descri- bed in the following. Example
X Pull oil dipstick :out of the oil dipstick
tube.
X Wipe off oil dipstick :.
X Slowly slide oil dipstick :into the guide
tube to the stop, and take it out again.
If the level is between MIN mark =and
MAX mark ;, the oil level is correct.
X If the oil level has dropped to MIN mark =
or below, top up with 1.0 l of engine oil.
