Driving economically ECO mode
ECO mode is a function that
optimises fuel consumption. It affects engine power and torque,
acceleration, gear shift indication,
heating, air conditioning and electrical consumers.
Activation
Press ECO. Control indicator ECO
illuminates in the instrument cluster when activated.
138Driving and operatingIf the Infotainment system is active,
audio sound may briefly be reduced
or interrupted during the restart.
Fault
If a fault occurs in the stop-start
system, the LED in Î illuminates,
and a corresponding message
appears in the Driver Information
Centre 3 101 . Seek the assistance of
a workshop.
Vehicle messages 3 102.
Warning chimes 3 103.
Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply parking brake without pressing release
button. Apply as firmly as
possible on a downhill slope or
uphill slope. Depress brake
pedal at the same time to
reduce operating force.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first gear. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear.
Turn the front wheels towards the kerb.
● Close the windows.
● Remove the ignition key from the ignition switch. Turn the
steering wheel until the
steering wheel lock is felt to
engage.
● Lock the vehicle by pressing e on
the remote control 3 24.
Activate the anti-theft alarm
system 3 36.
● The engine cooling fans may run
after the engine has been
switched off 3 166.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for approx.30 seconds before switching off, in
order to protect the turbocharger.
Vehicle storage 3 165.
Driving and operating139Engine exhaust9Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
soot particles out of the exhaust
gases. The system includes a self-
cleaning function that runs
automatically during driving without
any notification.
The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving
conditions. Autostop is not available
and fuel consumption may be higher
during this period. The emission of
smells and smoke during this process is normal.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and
if previous driving conditions did not
enable automatic cleaning, it will be
indicated by the illumination of control
indicators j 3 97 and Z 3 97 in the
instrument cluster. Seek the
assistance of a workshop
immediately.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on page 3 159 could damage the
catalytic converter or electronic
components.
Unburnt fuel will overheat and
damage the catalytic converter.
Therefore avoid excessive use of
the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
146Driving and operatingCaution
It is inadvisable to drive with hand
resting on the selector lever.
Gear shifting 3 98.
Stop-start system 3 135.
Brakes
The brake system comprises two independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when you depress the
brake pedal firmly. You need to use
considerably more force for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
If control indicator R illuminates in
the instrument cluster while driving
and a corresponding message
appears in the Driver Information
Centre 3 101, there is a fault in the
braking system. Seek the assistance
of a workshop immediately.Control indicator R 3 97.
Vehicle messages 3 102.
Antilock brake system Antilock brake system (ABS)
prevents the wheels from locking.
ABS starts to regulate brake pressure
as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting-off, the system performs a self-test which may be audible.
Control indicator u 3 98.
Fault
If control indicator u does not go out
a few seconds after the ignition is switched on, or if it illuminates while
162Driving and operatingTrailer hitch
General information
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment. Only use
towing equipment that has been
approved for your vehicle.
Driving characteristics and towing tips
In the case of trailers with brakes,
attach the breakaway stopping cable.
Before attaching a trailer, lubricate
the coupling ball. However, do not do so if a stabiliser, which acts on thecoupling ball, is being used to reduce
snaking movements. For trailers with
low driving stability the use of a
stabiliser is recommended.
A maximum speed of 50 mph must
not be exceeded, even in countries
where higher speeds are permitted.If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 213.
Trailer towing
Trailer loads The permissible trailer loads are
vehicle and engine-dependent
maximum values which must not be
exceeded. The actual trailer load is the difference between the actual
gross weight of the trailer and the
actual coupling socket load with the
trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In
general, they are valid for gradients
up to max. 12%.
The permitted trailer load applies up
to the specified incline and up to an
altitude of 1000 m above sea level.Since engine power decreases as
altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10% for every 1000 m of additional
altitude. The gross train weight does
not have to be reduced when driving
on roads with slight inclines (less than 8%, e.g. motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 207.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load is specified on the
towing equipment identification plate
and in the vehicle documents. Always aim for the maximum load, especially in the case of heavy trailers. The
vertical coupling load should never
fall below 25 kg.
Driving and operating163In the case of trailer loads of
1200 kg or more, the vertical coupling
load should not be less than 50 kg.
Rear axle loadWhen the trailer is coupled and the
towing vehicle fully loaded (including all occupants), the permissible rear
axle load (see identification plate or
vehicle documents) must not be
exceeded.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle / trailer combination is selectively braked until the snaking
ceases. While the system is working,
keep steering wheel as still as
possible.
Trailer stability assist is a function of
the Electronic Stability Control (ESC)
3 149.

168Vehicle careWhen the engine oil level has
dropped to the MIN mark, top-up
engine oil.Caution
Do not allow the engine oil level to drop below the minimum level!
We recommend the use of the same
grade of engine oil that was used at
the last change.
Between the MIN and MAX marks a
volume of approx. 2.1 l for engines R9M 408, R9M 413 and R9M 415
respectively approx. 3.5 l for engines
R9M 450 and R9M 452 can be filled
in.
The engine oil level must not exceed the maximum mark MAX on the
dipstick.Caution
Overfilled engine oil must be
drained or suctioned out. If the oil
exceeds the maximum level, do
not start the vehicle and contact a
workshop.
To prevent spillage when
replenishing the engine oil, we
recommend using a funnel to top-up the engine oil. Ensure funnel is
securely located onto the filler pipe.
After topping-up, put the funnel into a
plastic bag and stow it securely.
A stabilization of the engine oil
consumption will not take place until
the vehicle has been driven several
thousand miles. Only then can the
actual degree of consumption be
established.
If consumption exceeds more than
0.6 l every 600 miles after this
running-in period, consult a
workshop.
Fit the cap on straight and tighten it.
Engine air filter
Engine air flow indicator
On certain models, an indicator is
located in the engine induction
system and indicates if the air-intake
to the engine is restricted.
