atrailer G
Risk of accident
When reversin gthe vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle.
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
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.
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.
You will find installation dimensions and loads
in the "Technical data" section
(Y page 303).
The maximum drawbar load of the trailer
drawbar on the ball coupling is 75 kg. How-
ever, 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 payloa dand the rear
axle load are reduced by the actual nose-
weight.
Please notet hat when towing atrailer, PARK-
TRONIC* (Y page 140) and Parking Guid-
ance* (Y page 143) are only availabl ewith
limitations ,ornot at all.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use atrailer with aheight-adjustable trailer
drawbar. 194

In Germany, th emaximum permissible speed
for vehicle/trailer combinations depends on
th et ype of trailer and is either 80 km/h or
10 0k m/ h. In som ecountries ,higher maxi-
mum speeds are permissible for vehicle/
trailer combinations .Before beginnin gthe
journey, check th etrailer' sdocuments to see
what th emaximum permitted spee dis.
For certain Mercedes-Ben zvehicles, th emax-
imum permissible rear axle load is increased
when towing atrailer. Refer to th e"Technical
data" sectio ntofindo ut whether this applies
to your vehicle .Ifyou utilise any of th eadded
maximum rear axle load when towing atrailer,
th ev ehicle/trailer combinatio nmay not

When towing atrailer, your vehicle's handling
characteristic swill be different in comparison
to when driving without atrailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleratio nand gradi-

R has an increased braking distance
R is affected mor ebystron gc rosswinds
R demands mor esensitive steering
R consumes mor efuel
On lon gand steep downhill gradients ,you

shif trange 1,2or 3.
i This also applies if you have activated
cruise control, SPEEDTRONI CorDIS-
TRONIC PLUS*.
This will use th ebraking effect of th eengine,
so less braking will be required to maintain
th es peed. This relieves th eload on th ebrake
system and prevents th ebrakes from over-
heating and wearin gtoo quickly. If you need
additional braking ,depress th ebrak epedal
repeatedly rather than continuously. G
Ris

Never depress th ebrak epedal continuously
while th evehicle is in motion ,e.g.n ever cause

this reason, following acar wash, drive with
particula rcare unti lthe brakes are dry.
You can wash the vehicle in an automatic car
wash from the beginning.
! We recommend automatic car washes
with an adjustable 38
high-pressure pre-
cleaning program. In car washe sthat use
hig hw ater pressures, there is adanger that
as mall quantity of water may leak into the
vehicle.
! Cabriolet: do not treatthe vehicle with
hot wa xunder any circumstances.
! Cabriolet: pull the key ou tofthe ignition
lock whe nwashing the vehicle .This
ensures that the wind deflector on the
windscreen is retracted. The wind deflector
may otherwise be damaged.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! Make sure that the automatic car wash is
suitabl efor the size of the vehicle .Fold in
the exterior mirrors before the vehicle is
washed. There is otherwise ariskofd am-
ag etot he exterior mirrors.
! Whe nwashing your vehicle in atow-
through car wash, make sure that the auto-
mati ctransmission* is in position N.The
vehicle could otherwise be damaged.
! Make sure that the sid ewindow sare com-
pletel yclosed, that the ventilation/heater
blower is fully turne doff and that the wind-
scree nwiper switch is set to 0.Otherwise,
the rain/light senso rmay be activated, trig-
gering unintende dwiper movements. This
could cause damag etothe vehicle.
After using an automatic car wash, wipe off
wa xa nd drying agents from the windscreen and the wiper blades. Thi
swillp revent smears
and reduce wiping noises caused by residue
on the windscreen.
High-pressure cleaners G
Risk of accident
Do not us ehigh-pressure cleaners with circu-
lar-jet nozzle s(dirt grinders )toclean your
vehicle ,inparticula rthe tyres. You could oth-
erwise damag ethe tyre sand cause an acci-
dent.
! Observe the instructions issue dbythe
equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleane rand the
vehicle (a tleast 30 cm).
Move the high-pressure cleane rnozzle
around whe ncleaning your vehicle.
Do not ai mdirectl yata ny of the following:
R tyres
