Important hints for using the
parking assist systems9 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. If
such obstacles leave the detection area of the sensors during
approach of the vehicle, a
continuous warning tone will
sound.
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.
Notice
The parking assist system
automatically detects factory-fitted
towing equipment. It is deactivated
when the connector is plugged in.
The sensor may detect a non-
existent object (echo disturbance)
caused by external acoustic or
mechanical disturbances.
Notice
The parking assist is deactivated
when the rear carrier system is
extended.
Rear view camera The rear view camera assists the
driver when reversing by displaying a view of the area behind the vehicle.
The view of the camera is displayed
in the Colour-Info-Display.9 Warning
The rear view camera does not
replace driver vision. Note that
objects that are outside the
camera's field of view and the
Page 146 of 229

144Driving and operatingadvanced parking assist sensors,
e.g. below the bumper or
underneath the vehicle, are not
displayed.

limited. The distance of the image that appears on the display differs from
the actual distance.
Guiding lines
Dynamic guiding lines are horizontal
lines in 1 metre intervals projected on
the picture to define the distance to
shown objects.
Trajectory lane of the vehicle is
shown in accordance with the
steering angle.
The function can be deactivated in the
menu Settings in the Info-Display.

Speed limit signs are displayed in the
DIC until the next speed limit sign or
end of speed limit is detected or up to a defined sign timeout.
Combinations of more signs in the
display are possible.
An exclamation mark in a frame
indicates that there is an add on sign
detected which cannot be recognised
by the system.
The system is active up to a speed of 124 mph depending on the lighting
conditions. At night the system is
active up to a speed of 99 mph.
As soon as the speed becomes
slower than 34 mph the display will be
reset and the content of the traffic sign
page will be cleared. The next
recognised speed indication will be displayed.

Fuel for petrol enginesOnly use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 or equivalent.
Your engine is capable to run with
E10 fuel that fulfills these standards.
E10 fuel contains up to 10 %
bioethanol.
Use fuel with the recommended
octane rating 3 210. 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.

150Driving and operatingCaution
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.
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 to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and loss of
warranty.
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.
Fuel for liquid gas
operation
Liquid gas is known as LPG
(Liquefied Petroleum Gas) or under
its French name GPL (Gaz de Pétrole Liquéfié). LPG is also known as
Autogas.
LPG consists mainly of propane and
butane. The octane rating is between
105 and 115, depending on the
butane proportion. LPG is stored
liquid at around 5 - 10 bar pressure.
The boiling point depends on the
pressure and mixing ratio. At ambient pressure, it is between -42 °C (pure
propane) and -0.5 °C (pure butane).Caution
The system works at an ambient
temperature of approx. -8 °C to
100 °C.
Full function of the LPG system can
only be guaranteed with liquid gas
which complies with the minimum
requirements of DIN EN 589.
