Driving and operating115Parking■ 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 or
uphill slopes. Operate the foot
brake at the same time to reduce
operating force.
■ Switch off the engine and ignition. Turn the steering wheel until the
steering wheel lock is felt to
engage.
■ If the vehicle is on a level surface or
uphill slope, engage first gear
before switching off the ignition. On
an uphill slope, turn the front
wheels away from the kerb.
If the vehicle is on a downhill slope, engage reverse gear before
switching off the ignition. Turn the
front wheels towards the kerb.
■ Lock the vehicle and activate the anti-theft locking and anti-theft
alarm systems.Engine exhaust9 Danger
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
harmful 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
and the emission of smells and
smoke during this process is normal.
If cleaning of the filter is required and automatic cleaning does not occur, it
will be indicated by the illumination of
control indicator F and Z in the
instrument cluster. Seek the
assistance of a workshop
immediately.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on page 3 127, 3 172 could
damage the catalytic converter or
electronic components.
Unburnt fuel will overheat and
damage the catalytic converter.
Therefore avoid excessive use of
Driving and operating117Brakes
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, there is a fault in the braking
system. Seek the assistance of a
workshop immediately.Control indicator R 3 83.
Vehicle messages 3 87.
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.
Control indicator u 3 83.
Fault If control indicator u does not go out
a few seconds after the ignition is
switched on, or if it illuminates while driving, there is a fault in the ABS.
Control indicator F 3 82 may alsoilluminate in the instrument cluster
together with a corresponding
message in the Driver Information
Centre. The brake system remains
operational but without ABS
regulation.9 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 no longer be steered and may
swerve.
If control indicators u, F , R 3 83
and C 3 82 illuminate, the ABS and
ESP are deactivated and a
corresponding message appears in
the Driver Information Centre. Have
the cause of the fault remedied by a
workshop.

118Driving and operatingParking brake
Always apply parking brake firmly
without operating the release button,
and apply as firmly as possible on a
downhill or uphill slope.
To release the parking brake, pull the lever up slightly, press the release
button and fully lower the lever.
To reduce the operating forces of the
parking brake, depress the foot brake
at the same time.
Control indicator R 3 83.
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.
Brake assist is not available during an
Autostop.
Stop-start system 3 113.
Hill start assist The system helps prevent unintendedmovement 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
Traction Control system
The Traction Control system (TC) is a
component part of the Electronic
Stability Program (ESP® Plus
) which
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational as soon as the
ignition is switched on and control
indicator b extinguishes in the
instrument cluster.

126Driving and operating
ActivationRear view camera is automatically
activated when reverse gear is
engaged.
Functionality
The camera is mounted above the
rear doors/tailgate.
The area displayed by the camera is
limited. The distance of the image that
appears on the display differs from
the actual distance.
Trajectory lane display (1)
Depending on version, the trajectory
lane (1) of the vehicle is shown in blue
on the Info-Display. It shows the path of the vehicle in accordance with the
steering angle.
Fixed lane display (2)
The fixed lane display (2) shows the
path of the vehicle if the wheels are
kept straight.
Guiding lines (A, B, C) are used together with the fixed lane
display (2) and indicate the distance
behind the vehicle.
The guiding line intervals are as
follows:A (red)=30 cmB (yellow)=70 cmC (green)=150 cm
Settings
Settings, e.g. brightness, can be set
via the Infotainment system. Refer to
Infotainment system manual for
further information.
Deactivation
The camera is deactivated after a
delay if reverse gear is not engaged.
Fault The rear view camera may notoperate properly when:
■ the surrounding is dark,
■ the sun or the beam of headlights is
shining directly into the camera
lens,
■ ice, snow, mud, or anything else covers the camera lens. Clean the
lens, rinse it with water, and wipe it
with a soft cloth,
130Driving and operating
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
3 169.
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.In the case of trailer loads of
1200 kg or more, the vertical coupling load should not be less than 50 kg.
Rear axle load
When 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 isselectively braked until the snaking
ceases. While the system is working,
keep steering wheel as still as
possible.
Trailer stability assist (TSA) is a
function of the Electronic Stability
Program 3 119.
