Problem Possible causes/consequences and
M Solutions
Vehicles with
apetrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is
amalfunction in the engine electronics or amechanical
componen tofthe engin emanagement system.
X Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at aqualified specialist
workshop.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be lit and a
warning tone may
sound. (Y
page 192). The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X
Stop as soo naspossible and allow the engin eand the coolant
to cool down.
X Check the coolant level (Y page261). Observe the warning
notes as you do so and top up the coolan tifnecessary. If the coolan
tlevel is correc t,the radiator fan may be faulty. The
coolant is too hot and the engine is no longe rbeing cooled suffi-
cien tly.
X If the coolant temperature is less than 120 †, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop/start driving. Manual transmission

Whe nshifting between 5thand 6thgear,
you should always push the gear lever all
the way to the right. Otherwise, you could
shift uninte ntionally into 3rdor4th gear
and damage the transmission. Do not exceed the maximum speed for the
individual gears.
Shiftin
gdown at too high aspeed (trans-
mission braking) can cause the engine to
overrev ,leading to engine damage.
! On long and steep downhill gradients,
especiall yifthe vehicle is laden or towing
at railer, yo umust shift into gear 1, 2or3
in good time. This uses the engine's braking
effect .This relieves the load on the brake
system and prevents the brakes from over-

(Y page 313).
Low outsid etemperatures Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, various climate-dependent low-tem-
perature classes are defined in EN 590. Refu-
elling with diesel fuel which complies with the
climatic specification sofstandard EN 590
can hel ptoprevent operatin gproblems. At
exceptionall ylow tempera tures, it is possible
that the flow properties of the fuel ma ybe
inadequate. This is also the case for fuel that
has not been adapted to the climatic specifi-
cations ,e.g. diese lfuel for warmer areas.
i Further information about country-spe-
cific fuel properties can be obtained from
oil companies, e.g. at filling stations.
Flow improver Flow improvers can be added to improve the
cold resistance of diesel fuel. The effective- ness of
aflow improver is not guaranteed with
every fuel.

fuel system, e.g. by parking the vehicle in a

Cruise control
Import ants afety notes Cruise control maintain
saconstant road

to avoid exceeding the set speed. On long and
steep downhil lgradients ,especially if the
vehicle is laden or towing atrailer, yo umust
shift to alower gear in good tim eorselect
shift range 1,2or 3on vehicles with auto-
matic transmission. By doing so, you will
mak euse of the brakin geffect of th eengine,
which relieves the load on the brake system and prevents the brakes from overheating
and wearing too quickly. G
Risk of accident
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for aprolonged period. Yo ucan
store any road spee dabove 30 km/h. G
Risk of accident
Cruise control cannot take account of road
and traffic conditions.
Always pay atten tion to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for brakin gingood time. G
Risk of accident
Do not use cruise control:
R in road and traffic condition swhich do not
allow you to maintain aconstant speed (e.g.
heavy traffic or winding roads). You could
otherwise cause an accident.
R on slippery roads. Brakin goraccelerating
coul dcause the drive wheels to lose trac-
tion and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow

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
