i
On vehicles without level control, the
height of the ball coupling will alter accord-
ing to the load placed on the vehicle. If nec-
essary, use a trailer with a height-adjusta-
ble drawbar.
Coupling up a trailer G
Risk of injury
Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your hand could
become trapped between the bumper and
trailer drawbar.
! Do not disconnect a trailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the rebound-
ing of the overrun brake.
X Position the trailer level behind the vehicle.
X Couple up the trailer.
X Establish the electrical connection
between the vehicle and the trailer.
Driving tips G
Risk of accident
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 whether the
ball coupling is correctly engaged.
i Observe the notes on ESP ®
trailer stabi-
lisation (Y page 60).
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. Before beginning the journey,
check the trailer's documents to see what the
maximum permitted speed is. G
Risk of accident
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.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
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
R is affected more by strong crosswinds
R demands more sensitive steering
R consumes more fuel
On long and steep downhill gradients you
must select a lower gear in good time, or on
vehicles with automatic transmission*, select
shift range 1,2or 3.
i This also applies if you have activated
cruise control, Speedtronic or Distronic
Plus*.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously. G
Risk of accident
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. 236

Depending on how and where the vehicle is
used, there may be an increase in the
AdBlue ®
consumption, resulting in the next
service due date being brought forward.
The following messages tell you about the
AdBlue ®
supply:

Before taking a trip with your vehicle outside
Europe, have the AdBlue ®
supply checked
and, if necessary, topped up at a qualified
specialist workshop. Before using your vehi-
cle for an extended period in countries out-
side Europe, contact a qualified specialist
workshop.
! Have the AdBlue ®
tank topped up at a
qualified specialist workshop only. The
vehicle may otherwise be damaged or
soiled.
Damage or consequential damage is not
covered by the Mercedes-Benz implied
warranty.
You can obtain general information about
BlueTEC exhaust gas aftertreatment and
AdBlue ®
from any Mercedes-Benz Service
Centre.

Care and cleaning products
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use only care products and cleaning agents
recommended and approved by Mercedes-
Benz. !
For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
and do not scrub.
Do not touch the surfaces and protective
films with hard objects, e.g. rings or ice
scrapers. You could otherwise scratch or
damage the surfaces and protective film. H
Environmental note
Dispose of empty packaging, cleaning cloths
and polishing wads in an environmentally
responsible manner.
! Do not park the vehicle for a long period
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operating
temperature. Exterior care
Automatic car wash G
Risk of accident
The vehicle is braked when the HOLD function
or Distronic Plus* is activated. Therefore,
deactivate the HOLD function and Distronic
Plus before the vehicle is washed in an auto-
matic car wash. G
Risk of accident
Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, until the brakes are dry, drive with
particular care after the vehicle is washed.
You can wash the vehicle in an automatic car
wash from the beginning. 240

Coolant
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
i When the vehicle is first delivered, it is
topped up with a coolant that will ensure
adequate antifreeze and corrosion protec-
tion.
! Only top up with coolant that has been
premixed with the desired antifreeze pro-
tection. You could otherwise damage the
engine.
Further information on coolants and on fill-
ing can be found in the Mercedes-Benz
Specifications for Service Products, Sheet
310.1, or at any Mercedes-Benz Service
Centre. !
Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the cooling system will not be
sufficiently protected from corrosion, and
the boiling point will be too low.
If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point of
the coolant will be around 130 †.
The antifreeze/corrosion inhibitor concentra-
tion in the cooling system should:
R be at least 50%. This will protect the cooling
system against freezing down to around
-37 †.
R not exceed 55% (antifreeze protection
down to -45 †); otherwise, heat will not be
effectively dissipated.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor-
rosion inhibitor. Mercedes-Benz recom-
mends an antifreeze/corrosion inhibitor
which has been approved for Mercedes-Benz.
! The cooling system contains a supply
which must be renewed after 15 years, or
after 250, 000 km at the latest.
The warranty is only valid if you top up with
an antifreeze/corrosion inhibitor which
has been approved by Mercedes-Benz and
if the recommended mixture ratio is
observed. Brake fluid
Over a period of time, the brake fluid absorbs
moisture from the air; this lowers its boiling
point. G
Risk of accident
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
