on such
adynamometer, pleas econsult a
qualified workshop. You coul dotherwise
damage the drive train or the brake system.
4MATIC ensures that all four wheels are per-
manently driven. Togethe rwith ESP ®
and
4ETS, it improves the trac tion of your vehicle
whenever adrive whee lspins due to insuffi-
cient grip.
i In wintr ydriving conditions ,the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+ Styres), with snow
chain sifn eces sary.

DSR (Downhill Speed Regulation) Important safet
ynotes G
WARNING
DS Riso nlyana id designed to assist you when
drivin gdownhill .You are responsible for keep-
ing control of the vehicle and for assessing
whether the downhil lgradient can be man-
aged.
When activating DSR th evehicle may brake
suddenly due to DSR inter vening. Thi sis
dependent on the downhill gradien tand the
difference between the current speed and the
speed set. DSR may not alway sbeable to
keep to the set speed, depending on road sur-
fac eand tyre conditions .You coul dlose con-
trol of the vehicle and cause an accident.
Selec taset speed suitable for the prevailing
conditions and when necessary, apply the
brakes manually. G
WARNING
If you depress the accelerator pedal wit hDSR
activated, the nthe set speed can be excee-
ded. Drive downhill with specia lcare and
alway skeep in min dthat DSR brakes the vehi-
cle as soon as you remove your foot from the
accelerator pedal. The vehicle ma ybrake sud-
denly due to DSR intervening, depending on
th ed ownhill gradient and the differen ce between the current speed and the set speed.
You could lose control of the vehicl
eand
cause an accident.
DSR assists you whe ndriving downhill. It
keeps th espeed of travel at the speed set on
the on-boar dcomputer .The steeper the
downhill gradient ,the greater the DS Rbrak-
ing effect on th evehicle. When driving on flat
stretches of road or on an uphill gradient, the
DSR braking effect is minima lornon-existent.
DSR con trols the set speed when it is active
and the automatic transmission is in the D,
R or Nposition .Bya ccelerating or braking,
you can always drive at ahigher or alower
speed than that set on the on-boar dcom-
puter.

Changing th eset speed X
To increase or reduce the set speed in
1k m/h increments: briefly press the cruise control lever, up
:for ahigher set
speed or down ;for alower set speed.
The set speed appears in the multifunction
display with the ÃDSR symbol. It is also
displayed in status indicator =.
When DSR is activated, you can change the
set speed to avalue between 2km/h and
18 km/h.

The applicable permissible values, which
must not be exceeded, can be found:
R in the vehicle documents
R on the identification plates of the trailer tow
hitch, the trailer and the vehicle
If the values differ, the lowest value applies.
You will fin dthe values approved by the man-
ufacturer on the vehicle identification plates
and those for the towing vehicle under "Tech-
nical data "(Ypage 433).
When towing atrailer, your vehicle's handling
characteristics wil lbedifferent in comparison
to when drivin gwithout atrailer.
Th ev ehicle/ trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbin gcapability
R has an increased braking distance
R is affected more by stron gcrosswinds
R demand smore sensitive steering
R has alarger turnin gcircle
This could impair the handling charac teris-

Maintain asafe distance. Drive carefully.
When towing atrailer, alw aysa djust your
speed to the current road and weather con-
ditions. Do not exceed the maximum permis-
sible speed for your vehicle/trailer combina-
tion.
General notes !
Use adrawbar noseweigh tasc lose as
possible to the maximum permissible nose-
weight. Do not use anoseweight of less than 50kg, otherwise the trailer ma
ycome
loose.
Not ethat the payload and the rea raxle load
are reduce dbythe actual payload.

pressure table in the fuel filler flap of the
vehicle (Y page 399).
You will find installation dimensions and loads
in the "Technical data" section
(Y page 432).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 140 kg.
However, the actual noseweight must not
exceed the value given on the trailer tow hitch
or trailer identification plates .The lowest
weight applies.
Please not ethat when towing atrailer, PARK-

Driving tips i
Observ ethe information on ESP ®
trailer
stabilisation (Y page 67)and on pulling
away with atrailer. (Y page 162).
Vehicle swith the ON&OFFROAD pack-
age: select the trailer program (Y page 250)
with the off- road program selector wheel in
the centre console.
The maximum permissible spee dfor vehicle/
trailer combina tions depends on the type of
trailer .Befor ebeginning the journey, check
the trailer's document stosee what the max-
imu mpermitted speed is. Observ ethe legally
prescribed maximum speed in the relevant
country.
For cer tain Mercedes-Benz vehicles, the max-
imum permissible rear axle load is increased
when towing atrailer. See "Technica ldata" to
find out whethe rthis applies to your vehicle
(Y page 433). If you utilise any of the added
maximum rea raxle load whe ntowing atrailer,
