Risk of poisoning
Exhaust fumes could enter the vehicle interior
if the engine is running and the boot lid is
open. This could poison you. Therefore, you
should make sure that the boot lid is always
closed when the engine is running.
! The boot lid swings upwards when
opened. Therefore, make sure that there is
sufficient clearance above the boot lid.

Problem Possible causes/consequences and
M Solutions
Vehicles with a petrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is a malfunction in the engine electronics or a mechanical
component of the engine management system.
X
Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at a qualified specialist
workshop, e.g. a Mercedes-Benz Service Centre.
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. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 268). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the radiator fan may be faulty. The
coolant is too hot and the engine is no longer being cooled suffi-
ciently.
X At coolant temperatures under 120 †, drive on to the nearest
qualified specialist workshop e.g. to a Mercedes-Benz Service
Centre.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop/start driving. Automatic transmission
Important safety notes
G
Risk of accident
The movement of the pedals must not be
impaired in any way. Do not keep any objects
in the driver's footwell. Make sure that floor-
mats or carpets are correctly secured and
that there is sufficient clearance for the ped-
als.
Do not place several floormats on top of one
another. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you to lose control of your vehicle and cause an
accident. Automatic transmission

Problems with the transmission
Problem Possible causes/consequences and
M Solutions
The transmission has
problems shifting gear. The transmission is losing oil.
X
Have the transmission checked at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service Centre, immediately. The acceleration ability
is deteriorating.
The transmission no
longer changes gear. The transmission is in emergency mode.
It is only possible to shift into
secondgear and reverse gear.
X Stop the vehicle.
X Shift the transmission to position P.
X Switch off the engine.
X Wait at least 10 seconds before restarting the engine.
X Shift the transmission to position Dor R.
If D is selected, the transmission shifts into secondgear; ifRis
selected, the transmission shifts into reverse gear.

shop, e.g. a Mercedes-Benz Service Centre, immediately. Refuelling
Important safety notes
G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine and the auxiliary heating
before refuelling. G
Risk of injury
Do not come into contact with fuels.
It is hazardous to your health if your skin
comes into direct contact with fuels or you
breathe in fuel vapours. G
Risk of fire
Do not use petrol to refuel vehicles with a die-
sel engine. Do not mix diesel with petrol. This
would result in damage to the fuel system and
engine, which could lead to a vehicle fire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel vehicles with a petrol engine. Even a small
quantity of the wrong fuel will damage the
fuel system and engine.
! Do not switch on the ignition if you acci-
dentally refuel with the wrong fuel. Other-
wise, the fuel will enter the fuel lines. Notify
a qualified specialist workshop and have
the fuel tank and fuel lines drained com-
pletely. Petrol (EN 228)
Fuel grade !
Only refuel using unleaded premium-
grade petrol with at least
95 RON/85 MON, which conforms to Euro-
pean standard EN 228 or an equivalent
specification.
! Do not use the following:
R E85 (petrol with 85 % ethanol)
R E100 (100 % ethanol)
R M15 (petrol with 15 % methanol) 142

Risk of accident
The vehicle can be braked when DISTRONIC
PLUS is activated. For this reason, deactivate
DISTRONIC PLUS if the vehicle is to be set in
motion by other means (e.g. in a car wash or
by towing).
In order to activat eDISTRONIC PLUS, the fol-
lowing conditions must be fulfilled:
R the engine must be started, and you have
been driving for up to two minutes.
R the parking brake must not be applied.
R yourv ehicle must not be secured by the
electric parking brake.
R ESP ®
must be activated.
R the transmission must be in position D.
R the bonnet must be closed.
R the driver's door must be closed when you
shift from Pto Dor your seat belt must be
fastened.
R the front-passenger door and rear doors
must be closed.
R the vehicle must not skid. Activating while driving
When driving at speeds below 30 km/h, you
can only activate DISTRONIC PLUS if the vehi-
cle in fron
thas been detected and is shown
in the multifunction display. If the vehicle in
fron tis not shown in the multifunction display
and is no longer being detected, for example
because it has changed lanes, DISTRONIC
PLUS is deactivated and atone sounds.
X Briefly pull the cruise control lever towards
you ?or press it up :or down Ato the
pressure point.
DISTRONIC PLUS is selected.
X Keep the cruise control lever pressed
up : or down Auntil the desired speed
is set.
X Remove your foot from the accelerator
pedal.
Your vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
i If you do not fully release the accelerator
pedal, the DISTRONIC PLUS suspended message appears in the multifunction dis-
play. The set distance to a slower-moving
vehicle in front will then not be maintained.
You will be driving at the speed you deter-
mine by the position of the accelerator
pedal.
Activating when driving towards asta-
tionary vehicle
If the vehicle in front of you is stationary, you
can only activate DISTRONIC PLU Sonce your
vehicle is stationary as well.
X Briefly pull the cruise control lever towards
you ?.
DISTRONIC PLU Sis selected.
i DISTRONIC PLUS can only be activated at
under 30 km/h if a vehicle in front has been
detected. Therefore, the DISTRONIC PLUS
distance display in the instrument cluster
should be activated. 156

Risk of accident
Do not change dow nfor additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You can set a variable or permanent limit
speed:
R variable for speed limits, e.g. in built-up
areas
R permanent for long-term speed restric-
tions, e.g. when driving with winter tyres
fitted (Y page 164) G
Risk of accident
Speedtronic is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time.
i The speed indicated in the speedometer
may differ slightly from the limit speed
stored.
Variable SPEEDTRONIC General notes
With the cruise control lever, you can operate
cruise control or DISTRONIC PLUS and vari-
able SPEEDTRONIC.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:
R LIM indicator lamp off: cruise control or
DISTRONIC PLUS is selected.
R LIM indicator lamp on: variable SPEED-
TRONIC is selected.
You can use the cruise control lever to limit
the speed to any speed above 30 km/hw hile
the engine is running. :

Risk of accident
If there is a change of drivers, advise the new
driver of the limit speed stored.
Only use variable SPEEDTRONIC if you will not
have to accelerate suddenly to a speed above
that stored as the limit speed. You could oth-
erwise cause an accident.
You can only exceed the limit speed stored if
you deactivate variable SPEEDTRONIC:
