Cleaning the exhaust tail pipes G
WARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
! Do not clean the exhaust pipe with acid-
based cleaning agents, such as sanitary
cleanser or wheel cleaner.
! Mercedes-AMG vehicles with black
exhaust pipes: the black-chrome tailpipe
finishers should not be polished with a
chrome polish. They will otherwise lose
their black sheen. For optimal care, the fin- ishers should be rubbed with a lightly oiled
cloth after every car wash. Commercially
available engine and care oils are suitable
for this. For heavier soiling, you can apply a fine
paintwork polish with a microfibre cloth.
Remove the excess polish residue after pol-
ishing.
Impurities combined with the effects of road
grit and corrosive environmental factors may cause flash rust to form on the surface. You
can restore the original shine of the exhaust
pipe by cleaning it regularly, especially in win- ter and after washing the vehicle.
X Clean the exhaust pipe with a care product
tested and approved by Mercedes-Benz.
Cleaning the trailer tow hitch H
Environmental note
Dispose of oily and greasy cloths in an envi-
ronmentally-responsible manner.

Important safety notes
G
WARNING
Safety relevant functions are restricted or no
longer available if:
R the engine is not running
R the brake system or power steering is mal-
functioning
R there is a malfunction in the voltage supply
or the vehicle's electrical system
When your vehicle is towed away or towed
started, you may require considerably more
effort to steer and brake. There is a risk of an
accident.
In such cases use a rigid towing bar. Before
being towed away or tow started, make sure
the steering moves freely. G
WARNING
If the steering wheel lock is engaged, the vehi- cle can no longer be steered. There is a risk of
an accident.
Always switch on the ignition when towing
with a tow rope or a towing bar. G
WARNING
When towing or tow-starting another vehicle
and its weight is greater than the permissible gross weight of your vehicle, the:
R towing eye may be torn off
R car/trailer combination may swerve or
even overturn
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per- missible gross weight of your vehicle.
Details on the permissible gross vehicle
weight of your vehicle can be found on the
vehicle identification plate (Y page 402).
! When COLLISION PREVENTION ASSIST
PLUS, DISTRONIC PLUS or the HOLD func- tion is activated, the vehicle brakes auto-
matically in certain situations. To avoid

the towing eyes or, if available, to the trailer
tow hitch. You could otherwise damage the
vehicle.
! Observe the following points when towing
with a tow rope:
R Secure the tow rope on the same side on
both vehicles.
R Make sure that the tow rope is not longer
than legally permitted. Mark the tow rope
in the middle, e.g. with a white cloth
(30 x 30 cm). This will make other road
users aware that a vehicle is being
towed.
R Only secure the tow cable to the towing
eyes or, if available, to the trailer tow
hitch.
R Observe the brake lamps of the towing
vehicle while driving. Always maintain a
distance a distance so that the tow rope

Tyre pressure
Tyre pressure specifications
G
WARNING
Underinflated or overinflated tyres pose the
following risks:
R the tyres may burst, especially as the load
and vehicle speed increase.
R the tyres may wear excessively and/or
unevenly, which may greatly impair tyre
traction.
R the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident.
Observe the recommended tyre pressure and check the tyre pressure of all the tyres includ-
ing the spare wheel:
R at least every two weeks
R when the load changes
R before embarking on a longer journey
R for changed operating conditions, e.g. off-
road driving
If necessary, correct the tyre pressure. G
WARNING
If you fit unsuitable accessories onto tyre
valves, the tyre valves may be overloaded and malfunction, which can cause tyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This
can also result in tyre pressure loss. There is a risk of accident.
Only screw standard valve caps or valve caps
specifically provided by Mercedes-Benz for
your vehicle onto the tyre valve. G
WARNING
If the tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in a tyre
blow-out. There is a risk of accident.
R Check the tyre for foreign objects.
R Check whether the wheel is losing air or the
valve is leaking. If you are unable to rectify the damage, con-
tact a qualified specialist workshop.
H
Environmental note
Check the tyre pressure regularly, at least
every 14 days.
The recommended tyre pressures for various
operating conditions can be found in the tyre pressure table on the fuel filler flap
(Y page 189).
Operation with an emergency spare
wheel: information on operation with an
emergency spare wheel can be found in the
general notes in the "Emergency spare wheel"
section (Y page 396).
Operation with a trailer: the applicable
value for the rear axle is the maximum tyre
pressure value stated in the table inside the
fuel filler flap.
Additionally, the tyre pressure table may also state tyre pressures for different load condi-
tions. These are defined in the table as dif-
ferent numbers of passengers and amounts
of luggage. The actual number of seats may
vary; for more information, please refer to the
vehicle's registration documents.
If tyre sizes are not specified, the tyre pres-
sures stated on the tyre pressure table apply for all tyres approved for this vehicle. If a tyre size precedes a tyre pressure, the
following tyre pressure information is only
valid for that tyre size.
Use a suitable pressure gauge to check the
tyre pressure. The outer appearance of a tyre374
