Important safet ynotes G
WARNING
Only for the United Kingdom: if the vehicle
has been locked with the key, the double lock
function is activated as standard. It is then not
possible to open the doors from inside the
vehicle.
Therefore, do not leave any people behind in
the vehicle, particularly children ,elderly peo-
ple or people in need of special assistanc eif
the vehicle has been locked with the key. As
ar esult, they may not be able to free them-
selves in the event of an emergency. As a
result, they could be seriously or even fatally
injured by prolonged exposure to extremely
high or low temperatures, for example. In this
case, rescuin gpeople from outside the vehi-
cle is difficult.
Deactivate the interior motion sensor before
you lock the vehicle with the key. The doors
can then be opened from the inside after the
vehicle has been locked from the outside with
the key.
! The boot lid swings upwards when
opened. Therefore, make sure that ther eis
sufficien tclearance above the boot lid.

BootOpening and closing

Make sure that the following values are not
exceeded:
R the permissible trailer drawbar noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
You will find the applicable permissible val-
ues, which must not be exceeded, in the vehi-
cle documents.
You will find the values approved by the man-
ufacturer on the vehicle identification plates
and those for the towing vehicle in the "Tech-
nical data" section. G
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 whether the
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 atrailer, set the tyre pres-
sure on the rear axle of the towing vehicle
for am aximum load; see the tyre pressure
table in the fuel filler flap (Y page 321).
You will find installation dimensions and loads
in the "Technical data" section
(Y page 343).
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 anoseweight as close as possible to
the maximum permissible noseweight. Do
not use anoseweight 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 atrailer, PARK-
TRONIC (Y page 185) and parking guidance
(Y page 189) 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 atrailer with aheight-adjustable draw-
bar.
Driving tips i
Observe the notes on ESP ®
trailer stabi-
lisation (Y page 65).
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 atrailer. Refer to the "Technical Trailer towing
205Driving and parking Z

Tyre pressure
Tyre pressure specifications
Yo uw illf ind atable of tyr epressures for var-
ious operating conditions on the insid eof
your vehicle's fuel fille rflap.
Operation with emergency spare wheel:
The applicable value for the emergency spare
wheel is stated on the spare wheel and in the
technical data section.
Operation with atrailer: The applicable
value for the rear tyre sisthe maximum tyre
pressure value stated on the table insid ethe
fuel filler flap.
The table insid ethe fuel filler flap may state
tyre pressures for differen tload conditions.
These are defined in the table as different
numbers of passengers and amounts of lug-
gage. The actual number of seats may vary –
for more information please refer to the vehi-
cle's registration documents.
If no other data is stated, the tyre pressures
specified on the fuel filler flap apply for all
tyres approved for this vehicle. If
at yre size precedes atyre pressure, the tyre
pressure information following is only valid
for that tyre size. Instead of the complete tyre size, the rim
diameter alone, for example
R16,may be lis-
ted. Rim diameter
:is part of the tyre size and
can be found on the tyre sidewall. G
WARNING
Tyre pressure that is either too high or too low
has anegative effect on the vehicle's driving
safety, which could lead you to cause an acci-
dent. Therefore, you should regularly check
the pressure of all the tyres, particularly prior
to long trips, and correc tthe pressure as nec-
essary.
To test tyre pressure, use asuitable pressure
gauge. The outer appearance of atyre does
not permit any reliablec onclusion about the
tyre pressure. G
WARNING
Do not fit anything else to the tyre valve other
than the standard valve cap. In particular, ret-
rofitted tyre pressure monitors which are
screwed on to the valve may overload it and
cause it to fail. Due to their design, the valve Tyrep

eMercedes-Ben zparts
Mercedes-Ben ztests genuine parts and con-
version parts and accessories which have
been specifically approved for your vehicle for
their reliability, safety and suitability. Despite
ongoin gmarket research ,Mercedes-Benz is
unable to evaluate other parts. Mercedes-
Benzt herefore accepts no responsibility for
the use of such parts in Mercedes-Ben zvehi-
cles, even if they have been independently or
officially approved.
In Germany and some other countries, certain
parts are only officially approved for installa-
tion or modification if they comply with legal
requirements. All genuine Mercedes-Benz
parts meet this requirement .The use of non- approved parts may invalidate the vehicle's
general operating permit. This is the case if:
R
they cause achange of the vehicle type
from that for which the vehicle's general
operating permit was granted.
R other road users could be endangered.
R the emission or noise levels are adversely
affected. G
WARNING
Driving safety may be impaired if non-
approved parts, tyres and wheels or safety-
relevant accessories are used.
This could lead to malfunctions in safety-rel-
evant systems, e.g. the brake system. This
could cause you to lose control of your vehicle
and cause an accident.
For this reason, Mercedes-Ben zrecommends
that you use genuine Mercedes-Benz parts or
parts of equal quality. Only use tyres, wheels
and accessories that have been specifically
approved for your vehicle.
! Airbags and seat belt tensioners, as well
as control units and sensor sfor these
restraint systems may be installed in the
following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R dashboard
R instrument cluster
R centre console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operatin gefficiency of the restraint sys-
tems.
Have aftermarket accessories installed at
aq ualified specialist workshop. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centr efor this pur-
pose. 330
