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, add 0.5to 1.0litre of engine
oil.
Adding engine oil G
WARNING
If engine oil comes into contact with hot
engine parts, it may ignite and you could burn
yourself. Do not spill any engine oil on hot
engine parts. H
Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment.
! Only use engine oils and oil filters that
have been approved for vehicles with a
service system. You can obtain a list of the
engine oils and oil filters tested and
approved in accordance with the
Mercedes-Benz Specifications for Service
Products at any Mercedes-Benz Service
Centre.
Damage to the engine or exhaust system is
caused by the following:
R using engine oils and oil filters that have
not been specifically approved for the
service system
R changing the engine oil and oil filter after
missing the change interval required by
the service system
R using engine oil additives
! Do not add too much oil. Topping up with
too much engine oil can result in damage
to the engine or to the catalytic converter.
Have excess engine oil siphoned off. Example: engine oil cap
X
Turn cap :anti-clockwise and remove it.
X Top up the engine oil.
If the oil level is at or under the MIN mark
on the oil dipstick, add 0.5 to 1.0 litre of
engine oil. Engine compartment

The BlueTEC exhaust gas aftertreatment

Unde rnormal operating conditions, a full tank
of AdBlue ®

Depending on how and where the vehicle is
used, there may be an increase in the
AdBlue ®

You can no longer start the engine when the
AdBlue

supply has been used up
(Y page 265).
Before taking a trip with your vehicle outside
Europe, have the AdBlue ®
supply checked at
a qualified specialist workshop. If necessary,
have the AdBlue ®
topped up. Before using
your vehicle for an extended period in coun-
tries outside Europe, contact a qualified spe-
cialist workshop. !
Have the AdBlue ®

Notes on care
Regula rcare of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz.
! For cleaning your vehicle, do no tuse any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film. H
Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man-
ner.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up. 326

Tyre pressure of at least 180 kPa
(1.8 bar/26 psi) is no treached If a pressure of 180 kP
a(1 .8 ba r,26 psi) has
not bee nachieved afte rfive minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose fro mthe valve of
the faulty tyre.
X Very slowly drive forwards or reverse
approximately 10 m.
X Pump up the tyre again.
After a maximum of five minutes the tyre
pressure must be at least 180 kPa (1.8 bar,
26 psi). G
WARNING
If the required tyre pressure is not reached
after the specified time, the tyre is too badly
damaged. The tyre sealant cannot repair the
tyre in this instance. Damaged tyres and a tyre
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
Tyre pressure of 180 kPa (1.8 bar/
26 psi) is reached X
Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tyre.
! After use, excess tyre sealant may run out
of the filler hose. This could cause stains.
Therefore, place the filler hose in the plastic
bag that contained the TIREFIT kit.
X Stow the tyre sealant bottle, the tyre infla-
tion compressor and the warning triangle.
X Pull away immediately. G
WARNING
At yre temporarily sealed with tyre sealant
impairs the driving characteristics and is not
suitable for higher speeds .There is a risk of
accident. You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed
the specified maximum speed with a tyre that
has been repaired using tyre sealant.
The maximum speed for a tyre sealed with
tyre sealant is 80 km/h. The "max. 80 km/h"
sticker must be affixed to the instrumentc lus-
ter within the driver's field of vision.
X Stop after driving for approximately ten
minutes and chec kthe tyre pressure with
the tyre inflation compressor.
The tyre pressure must now be at least
130 kPa (1.3 bar, 19 psi). G
WARNING
If the required tyre pressure is not reached
after driving for a short period, the tyre is too
badly damaged. The tyre sealant cannot
repair the tyre in this instance. Damaged tyres
and a tyre pressure that is too low can signif-
icantly impair the vehicle's braking and driv-
ing characteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
i In your vehicle, you will find a sticker with
the Mercedes-Ben zService24h telephone
number, e.g. on the B-pillar on the driver's
side.
X Correct the tyre pressure if it is still at least
130 kPa (1.3 bar, 19 psi) (for the values,
see the fuel filler flap).
X To increase the tyre pressure: switch on
the tyre inflation compressor. Flat tyre

are higher than those shown by the on-
board computer. In this case, do no treduce
the tyre pressures.
i The operation of the tyre pressure moni-
tor can be affected by interference from
radio transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.
Checking tyre pressure electronically X
Make sure that the key is in posi-
tion 2(Ypage 155) in the ignition lock.
X Press the =or; button on the steer-
ing wheel to select the Serv. menu.
X Press the 9or: button to select
Tyre pressure .
X Press the abutton.
The curren ttyre pressur efor each wheel
will be displayed in the multifunction dis-
play.
If the vehicle has been parked for longer than
20minutes, the Tyre pressures will be displayed after a few minutes of
driving message appears.
After a teach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. As long as a clear
allocation of the tyre pressure values to the
individual wheels is not possible, the Tyrepressure monitor active display mes-
sage is shown instead of the tyre pressure
display .The tyre pressures are already being
monitored.
i If a spare wheel/emergency spare wheel
is fitted, the system may continue to show
the tyre pressure of the wheel that has
been removed for a few minutes. If this
occurs, note that the value displayed for
the position where the spare wheel/emer-
gency spare wheel is fitted is not the same
as the spare wheel/emergency spare
wheel's current tyre pressure. Warning messages of the tyre pressure
monitor If the tyre pressure monitor detects a signifi-
cant pressure loss on one or more tyres, a
warning message is shown in the multifunc-
tion display.
Awarning tone also sounds and
the tyre pressure warning lamp lights up in
the instrument cluster.
Each tyre that is affected by a significant loss
of pressure is highlighted in the pressure dis-
play.
If the Please correct tyre pressure message appears in the multifunction dis-
play:
X
Chec kthe tyre pressure on all four wheels
and correct it if necessary.
i If the wheel positions on the vehicle are
interchanged, the tyre pressures may be
displayed for the wrong positions for a
short time. This is rectified after a few
minutes of driving, and the tyre pressures
are displayed for the correct positions.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the refer-
ence values for monitoring. In most cases, the
tyre pressure monitor will automatically
detect the new referencev
alues after you
have changed the tyre pressure.
i For an overview of th emenus, see
(Y page 234).
If you wish to define the new reference values
manually:
X Use the table on the inside of the fuel filler
flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operating conditions. Tyre pressure
