Flow improver
Flow improvers can be added to improve the
cold resistance of diesel fuel .The effective-
ness of a flow improver is not guaranteed with
every fuel.
Correct dosage and thorough mixing are deci-
sive factors in ensuring improvement in low-
temperature resistance. Under certain cir-
cumstances, an excessive dosage may
actually decrease low-temperature resist-
ance and should therefore be avoided. Follow
the manufacturer's dosing instructions.
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Malfunctions can other-
wise only be rectified by heating the entire
fuel system, e.g. by parking the vehicle in a
heated garage.
Observe the information provided by the man-
ufacturer when using a flow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz. You can obtain
further information from any Mercedes-Benz
Service Centre. Refuelling

WARNING
If the Check trailer hitch locking mechanism message appears in the multi-
function display while the vehicle is in motion,
pull over immediately and check whethe rthe
ball coupling is correctly engaged. G
WARNING
Always observe the maximum speed permit-
ted in Germany for vehicle/trailer combina-
tions, even in countries where higher speeds
are permitted. This lowers the risk of an acci-
dent. G
WARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely. G
WARNING
On no account should you attempt to draw the
vehicle/trailer combination out by increasing
speed.
General information i
When towing a trailer, set the tyre pres-
sure on the rear axle of the towing vehicle
for a maximum load; see the tyre pressure
table in the fuel filler flap (Y page 339).
You will find installation dimensions and loads
in the "Technical data" section
(Y page 361).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 75 kg.
However, the actual noseweight must not
exceed the value given on the trailer tow hitch
and trailer identification plates. The lowest
weight applies.
! Use a noseweight as close as possible to
the maximum permissible noseweight. Do
not use a noseweight of less than 50 kg,
otherwise the trailer may come loose. Bear in mind that the payload and the rear
axle load are reduced by the actual nose-
weight.
Please note that when towing a trailer, PARK-
TRONIC (Y page 179), parking guidance
(Y page 183) and Blind Spot Assist
(Y page 190) are only available with limita-
tions, or not at all.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use a trailer with a height-adjustable draw-
bar.
Driving tips i
Observe the notes on ESP ®
trailer stabi-
lisation (Y page 70).
In Germany, the maximum permissible speed
for vehicle/trailer combinations depends on
the type of trailer, and is either 80 km/h or
100 km/h. In some countries, higher maxi-
mum speeds are permissible for vehicle/
trailer combinations. Before beginning the
journey, check the trailer's documents to see
what the maximum permitted speed is.
For certain Mercedes-Ben zvehicles, the max-
imum permissible rear axle load is increased
when towing a trailer. Refer to the "Technical
data" section to find out whether this applies
to your vehicle. If you utilise any of the added
maximum rear axle load when towing a trailer,
the vehicle/trailer combination may not
exceed a maximum speed of 100 km/h for
reasons concerning the operating permit.
This also applies in countries in which the
permissible maximum speed for vehicle/
trailer combinations is above 100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be differen tincomparison
to when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbing capability
R has an increased braking distance 200

Tyre pressure monitor warning mes-
sages If the tyre pressure monitor detects a signifi-
cant pressure loss on one or more tyres, a
warning message is shown in the multifunc-
tio nd isplay. 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 214).
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. Also observe the notes in the section on
tyre pressures (Y
page 339).
X Make sure that the key is in position 2in
the ignition lock.
X Press the =or; button on the steer-
ing wheel to select the Service menu.
X Press the 9or: button to select
Tyre pressure .
X Press the abutton.
The multifunction display shows the cur-
rent tyre pressure of the individual tyres or
the Tyre pressures will be dis‐ played after a few minutes of driv‐
ing message.
X Press the :button.
The Use current pressures as new reference values message appears in
the multifunction display.
If you wish to confirm the restart:
X Press the abutton.
The Tyre press. monitor restarted message appears in the multifunction dis-
play.
After you have driven for a few minutes, the
system checks whether the current tyre
pressures are within the specified range.
The new tyre pressures are then accepted
as reference values and monitored.
If you wish to cancel the restart:
X Press the %button.
The tyre pressure values stored at the last
restart will continue to be monitored.
Radio type approval for the tyre pres-
sure monitor In certain countries, a radio type approval for
the tyre pressure monitor may be required.
The radio type approval number for the tyre
pressure monitor can be found online at:

Wheel and tyre combinations
Please bear the following in mind
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for you rvehi-
cle.
These tyres have been specially adapted
for use with the control systems, such as
ABS or ESP ®
, and are marked as follows:
R MO =Mercedes-BenzO riginal
R MOE =Mercedes-BenzO riginal Extended
(tyres with run-flat characteristics)
R MO1 =Mercedes-BenzO riginal (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with aload, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components.T his could result in dam-
age to the tyres or the vehicle.
Mercedes-Ben zaccepts no liability for
damage resulting from the use of tyres,
wheels or accessories othe rthan those tes-
ted and approved.
Further information about tyres, wheels
and approved combinations can be
obtained from any Mercedes-Benz Service
Centre.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Ben zcannot guarantee vehicle
safety if retreaded tyres are fitted. Do not fit used tyres if you have no information
about their previous usage.
! Large wheels :the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as a result of driving over obstacles
increases.
i You will find a table of tyre pressures on
the inside of your vehicle's fuel filler flap.
For further information on tyre pressure,
see (Y page 339).
