Driving and operating137Brakes
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 the brake pedal
is depressed firmly. Considerably
more force is needed 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.
Control indicator R 3 85.
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 86.
Fault9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can nolonger be steered and may
swerve.
You can continue driving, provided
you drive with care and anticipation.
Have the cause of the fault remedied
by a workshop.
Parking brake Electrical parking brake

138Driving and operating
Applying when vehicle is stationary
Pull switch m, the electrical parking
brake operates automatically with
adequate force. For maximum force,
e.g. parking with a trailer or on
inclines, pull switch m twice.
The electrical parking brake can
always be activated, even if the
ignition is off.
Do not operate electrical parking
brake system too often without
engine running as this will discharge
the battery.
Before leaving the vehicle, check the
electrical parking brake status.
Control indicator m 3 86.
Releasing
Switch on ignition. Keep foot brake
depressed and then push switch m.
If the foot brake is not depressed
when attempting to release electrical
parking brake, a warning chime will
sound and control indicator -
illuminates in the instrument cluster
3 90.Drive away function
With the engine running, selecting a
forward gear (manual transmission)
or engaging D (automatic
transmission) and then depressing the accelerator pedal automatically
releases the electrical parking brake.
This is not possible when the switch
m is pulled at the same time.
This function also helps driving away
on inclines.
Aggressive drive away may reduce
life time of wear parts.
Dynamic braking when vehicle is
moving
When the vehicle is moving and the
switch m is kept pulled, a warning
chime will sound and the electrical
parking brake system will decelerate
the vehicle, but will not apply
statically.
As soon as the switch m is released,
dynamic braking will be stopped.Fault
Failure mode of electrical parking
brake is indicated by control indicator
j 3 86.
In the event of a fault, to apply
electrical parking brake: pull and hold the switch m for a few seconds. If
control indicator m illuminates,
electrical parking brake has been applied successfully.
To release electrical parking brake:
push and hold the switch m for a few
seconds. If control indicator m
extinguishes, electrical parking brake
has been released successfully.
If control indicator m flashes:
electrical parking brake is not fully
applied or released. When m is
continuously flashing, with ignition switched on depress brake pedal,
release electrical parking brake and
retry applying.
If m continues to flash, do not drive
the vehicle. If necessary, place
wedge blocks or equivalent in front of and behind wheels to prevent vehicle

Driving and operating139
movement. Seek the assistance of a
workshop to have the cause of the
fault remedied.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking
is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Hill start assist
The system helps prevent unintended movement when driving away on
inclines.
When releasing the foot brake after
stopping on an incline, the brakes
remain on for a further 2 seconds. The brakes release automatically as soon
as the vehicle begins to accelerate.Ride control systems
Electronic Stability Control
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip. It also
prevents the drive wheels from
spinning.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the
wheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
ESC is operational as soon as control indicators b and t extinguish in the
instrument cluster after switching on the ignition.
When ESC is active b flashes 3 87.9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Deactivation
With ESC active, if wheels are
slipping on wet, snowy or icy roads,
engine speed may not increase when
accelerator pedal is depressed. The
vehicle may not move.

140Driving and operating
Switch off ESC function, to allow
engine rpm to increase, by pressing
button t briefly. Control indicator t
illuminates in the instrument cluster.
ESC is reactivated by pressing button
t again. The control indicator
extinguishes.
Control indicator t 3 88.
Hydraulic brake assist
When the ESC function comes into
action and recognises any
emergency situation requiring hard
braking, it automatically delivers
increased braking pressure to the
wheels.
Active rollover protection If the vehicle moves in an unstable
manner, this function helps the
vehicle maintain normal stability.
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 system is working keep steering wheel as still as possible.Descent control system
The Descent control system (DCS)
allows the vehicle to travel at a low
speed without depressing the foot
brake. The vehicle will automatically
decelerate to a low speed and remain
at that speed when the system is
activated. Some noise or vibration
from the brake system may be
apparent when the system is active.Caution
Use only when descending steep
grades while driving off-road. Do
not use when driving on normal
road surfaces. Unnecessary
usage of the DCS function, such
as while driving on normal roads,
may damage the brake system
and the ESC function.
Activation
At speeds below approx. 30 mph,
press button u. The green control
indicator u flashes in the instrument
cluster, to show DCS is in operation.
DCS will not activate at speeds above 30 mph, even if the button is pressed.
Deactivation
Press button u again. The green
control indicator u extinguishes.
Depressing the foot brake or
accelerator will also cause the system to be deactivated.

144Driving and operating
If the acoustic signal sounds 3 times
continuously when there are no
obstacles near the front or rear
bumper, there is a fault in the system.
Have the cause of the fault remedied by a workshop.
Important hints for using theparking assist system9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention has to be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the system can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and correct distance indication in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist systems do not
detect objects outside the
detection range.
Fuel
Fuel for petrol engines
Only use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 or equivalent.
Your engine is capable of running
with E10 fuel that fulfills these
standards. E10 fuel contains up to
10 % bioethanol.
Use fuel with the recommended
octane rating 3 205. Use of fuel with
too low an octane rating can reduce
engine power and torque and slightly
increases fuel consumption.Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.

Driving and operating145Caution
Use of fuel that does not comply toEN 228 or E DIN 51626-1 or
equivalent can lead to deposits or
engine damage and may affect
your warranty.
Caution
Use of fuel with too low an octane
rating could lead to uncontrolled combustion and engine damage.
Notice
Use unleaded Premium fuel only for
the following countries:
Armenia, Azerbaijan, Belarus,
Moldova.
Fuel for ethanol adapted
engines (E85) If access to E85 is limited then fuel
with a different proportion of ethanol
or normal RON 95 can be used for
refuelling. The engine's control
management system is adjusted
automatically according to the
amount of ethanol in the fuel.
E85 fuel must fulfil the CWA 15293 or
SS 155480 standard.
When the temperature is about
-10 °C or lower a greater proportion of petrol should be used. E85 in
combination with low temperatures
could lead to the car being more
difficult to start. A slightly higher
proportion of petrol improves the cold start properties considerably.
During the engine's warm-up phase
(below +50 °C) engine torque is
limited when driving with a proportion of ethanol.
Ethanol contains less energy per litre
than petrol, which is why fuel
consumption increases when driving
on E85 compared with petrol. A
consequence of this is that a tank of
E85 covers fewer miles than a tank of petrol.Caution
Certain additives in petrol could, in
combination with ethanol, cause
reduced driveability. For this
reason, refuel with a full tank of
petrol every 6,000 miles. Use up
the majority of this before
refuelling the vehicle again.
Fuel for diesel engines
Only use diesel fuel that complies
with EN 590.
In countries outside the European
Union use Euro-Diesel fuel with a
sulphur concentration below 50 ppm.
Caution
Use of fuel that does not comply
with EN 590 or similar can lead to engine power loss, increased
wear or engine damage and loss
of warranty.

146Driving and operating
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
Refuelling9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers. Switch off
any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
Caution
In case of misfuelling, do not
switch on ignition.
Fuel filler flap is located at left rear
side of vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked 3 21.
Release the fuel filler flap by pushing the flap.
To unlock fuel filler cap: turn it
anticlockwise. If hissing occurs, wait
until it stops before completely
unscrewing the cap.
The fuel filler cap can be retained in
the holder on the inside of the fuel
filler flap.
When refuelling, fully insert the pump nozzle and switch it on.
After the automatic cut-off, the fuel
tank can be topped up with a
maximum two doses of fuel.Caution
Wipe off any overflowing fuel
immediately.
After refuelling, replace the fuel filler
cap and turn it clockwise until you
hear several clicks. Ensure the cap is
screwed in completely, otherwise
control indicator Z may illuminate in
the instrument cluster 3 85.
Close fuel filler flap.
Fuel filler cap
Only a genuine fuel filler cap provides
full functionality. Diesel-engined
vehicles have special fuel filler caps.

148Driving and operating
If no eye is available, loop cable
around coupling ball bar. Ensure
cable is crossed under the vertical
coupling socket to ensure the trailer
nose cannot drop to the ground if it
becomes separated from the trailer
hitch. Do not allow the cable to drag
along the ground and always allow
enough slack to permit full turning.
Follow the instructions supplied with
the towing equipment.
Before attaching a trailer, lubricate
the coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce snaking movements. For trailers with
low driving stability, the use of a
friction-type stabiliser is strongly
recommended.
Do not drive faster than 50 mph, even
in countries where higher speeds are
permitted. When driving uphill, do not drive faster than 20 mph in 1st gear,
or 30 mph in 2nd gear.
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 3 210.
Trailer towing Trailer loads
The permissible trailer loads are
vehicle-dependent 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.
When the trailer load is being
checked, therefore, only the trailer
wheels - and not the jockey wheel -
must be standing on the weighing
apparatus.
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 metres 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 metres 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
3 201.
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 (80 kg) is specified on
the towing equipment identification
plate and in the vehicle documents.
Always aim for the maximum load,

Driving and operating151
Unlock coupling ball bar and remove
key. Push lever to the left, towards the
coupling ball bar and turn it
downwards. Pull coupling ball bar out of coupling housing.
Remove any rust or dirt from area
around the coupling housing and
coupling ball bar connection before
inserting sealing plug in the hole.
Place the coupling ball bar in the bag supplied, fasten it with the strap and
stow it below the floor cover in the
load compartment.
Do not use steam-jet cleaners or
other high-pressure cleaners to clean
the coupling ball bar.
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 system is working keep steering wheel as still as possible.
Trailer stability assist (TSA) is a
function of the Electronic Stability
Control 3 139.
