pull ove rimmediately and check whether the
ball couplin giscorrectly engaged.
i Observ ethe note sonE SP®
trailer stabi-
lisation (Y page 55).
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
excee damaximum spee dof100km/h for
reason sconcernin gthe operatin gpermit. This also applies in countries in whic
hthe
permissible maximum spee dfor vehicle/
trailer combinations is abov e100 km/h. G
Ris
kofa ccident
Always observ ethe maximum spee dpermit-
te dinG ermany for vehicle/traile rcombina-
tions ,eveninc ountries wher ehigher speeds
are permitted. This lower sthe riskofana cci-
dent.
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-
ent-climbin gcapability
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
must selec talower gear in good time, or on
vehicle switha utomatic transmission*, select
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
kofa ccident
Never depress th ebrak epedal continuously
while th evehicle is in motion ,e.g.n ever cause
th eb rakes to rub by applyin gconstant slight
pedal pressure .This causes th ebrak esystem
to overheat, increases th ebraking distance
and can lead to th ebrakes failin gcompletely. Trailer towing*
