Gen
eral information i
When towing atrail er,s et the tyr epres-
sure on th erear axle of the towing vehicle
for am aximum load; se ethe tyr epressure
table in th efuel filler flap.
You will find installatio ndimensions and loads
in the "Technical data” section
(Y page 322).
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 ma ycome loose.
Bear in min dthat the payload and the rear
axl eload ar ereduced by the actual nose-
weight.
Please not ethat when towing atrailer, PARK-
TRONIC (Y page 174) and parkin gguidance
(Y page 177 )are onl yavail ablew ith limita-
tions, or not at all.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use atrailer wit haheight-adjustable draw-
bar.
Driving tips i
Observ ethe notes on ESP ®
trailer stabi-
lisation (Y page 58).
In Germany, the maximum permissible speed
for vehicle/ trailer combinations depends on
the type of trailer and is either 80 km/ hor
100 km/h. In some countries ,higher maxi-
mum speeds are permissible for vehicle/
trailer combinations. Befor ebeginnin gthe
journey ,check the trailer's documen tsto see
what the maximum permitted speed is.
For certain Mercedes-Benz vehicles, the max-
imum permissible rear axle load is increased
when towing atrailer. Refer to th e"Technical data
"section to fin dout whether this applies
to your vehicle. If you utilise any of the added
maximum rear axle load when towing atrailer,
th ev ehicle/ trailer combination may not
exceed amaximum spee dof100 km/h for
reasons concerning the operating permit.
This als oapplies in countries in which the
permissible maximum speed for vehicle/
trailer combinations is above 10 0km/h.
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 consume smore fuel
On long and steep downhil lgradients ,you
must shift to alower gear in good time, or on
vehicles with automatic transmission ,select
the shift range 1,2or 3.
i This also applies if you have activated
cruise control, SPEEDTRONIC or DI S-
TRONIC PLUS.
This will use the brakin geffect of th eengine,
so les sbraking wil lberequired to maintain
the speed. This relieves the load on the brake
system and prevent sthe brakes from over-
heating and wearing too quickly .Ifyou need
additional braking, depress the brake pedal
repeatedly rather than con tinuously.
Driving tips R
Maintain agreater distance from th evehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from astandstill refer to sea 188

not ethat the power output of the engine,
and consequently the vehi cle's gradient-

Risk of accident
Only use the on-board computer when road
and traf ficc ondition spermit .You would oth-
erwise be distracted and unable to concen-
trate properly on driving, and coul dcause an
accident. G
Risk of accident
If the instrument cluster or multifunc tion dis-
play fails, no messages can be displayed.
This means that you will not see information
about the driving situation ,such as the speed,
outside temperature, warning/indicator
lamps, display message sorsystem failures.
Handling characteristics may be affected.
Adapt your driving style and speed accord-
ingly.
Immediately consult aqualified specialist
workshop which has the necessary specialist
knowledg eand tool stocarry out the work
required. Mercedes-Benz recommends that
you use aMercedes-Benz Servic eCentr efor
this purpose. In particular ,work relevant to
safet yorons afety-related systems must be
carried out at aqualified specialist workshop. G
Risk of accident
The on-board computer only records and dis-
plays malfunctions and warnings from certain
systems. For this reason, you should always make sure that your vehicle is safe to use. You
could otherwis
ecause an accident by driving
an unsafe vehicle. G
Risk of accident and injury
The operating safety of your vehicle could be
jeopardise difmaintenance work is carried
out incorrectly. As aresult, you could lose
control of the vehicle and cause an accident.
In addition ,the safety system smay no longer
be able to protec tyou or other sasthey are

Always have maintenanc ework carried out at
aq ualified specialist workshop .The qualified
specialist workshop must hav ethe necessary
specialist knowledge and tools to carry out
the wor krequired. Mercedes-Benz recom-
mends that you use aMercedes-Benz Service
Centr efor this purpose. In particular ,work
relevant to safet yoronsafety-related sys-
tems must be carried out at aqualified spe-
cialist workshop. Displays and operation
Coolant temperature gauge
The coolant temperature gauge is in the
instrument cluster on the right-hand side.
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 120 †.
The coolant temperature may rise to the top
end of the scale at high outsid etemperatures
and on long uphill stretches. Rev counter
The red band in the rev coun terindicate sthe
