Parking assist
The parking assist makes parking
easier by measuring the distance between the vehicle and obstacles,
and giving acoustic signals. It is the
driver, however, who bears full
responsibility for the parking
manoeuvre.
The system consists of four ultrasonic parking sensors in the rear bumper. If
the vehicle is equipped with a front
parking assist the system consists of
four additional ultrasonic parking
sensors in the front bumper.
Activation
After ignition is switched on, the rear
parking assist is activated.
The front parking assist can also be activated at a low speed by pressing
r .
An illuminated LED in the parking
assist button indicates that the
system is ready to operate.
An obstacle is indicated by a buzzing
sound. The interval between the sounds becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm, the buzzing is continuous.

automatically at a certain speed.
Fault
In the event of a fault in the system, a vehicle message is displayed in theDriver Information Centre.
Additionally, a vehicle message is
displayed in the Driver Information
Centre if a malfunction of the system
due to temporary conditions, e.g.
snow covered sensors is detected.Vehicle messages 3 104.
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.
Note
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.
158Driving and operatingNote
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 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
parking assist sensors, e.g. below
the bumper or underneath the
vehicle, are not displayed.
Do not reverse or park the vehicle
using only the rear view camera.
Always check the surrounding of
the vehicle before driving.
Activation
Rear view camera is automatically
activated when reverse gear is
engaged.
Functionality
The camera is mounted in the tailgate handle and has a viewing angle of
130°.
Due to the high position of the
camera, the rear bumper can be seen
on the display as a guide to position.
The area displayed by the camera is
limited. The distance of the image that
appears on the display differs from
the actual distance.
Guiding lines
Dynamic guiding lines are horizontal
lines at 1 m intervals projected on the
picture to define the distance to
displayed objects.
Driving and operating159
Trajectory lane of the vehicle is
shown in accordance with the
steering angle.
Warning symbols
Warning symbols are indicated as
triangles 9 on the picture which show
obstacles detected by the rear
sensors of the advanced parking
assist.
Additionally 9 appears on the top line
of the Info Display with the warning to
check the vehicle surrounding.
Deactivation
The camera is deactivated when acertain forward speed is exceeded or
if reverse gear is not engaged for
approx. 10 s.

● 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.
● The vehicle is towing a trailer.
Driving and operating165Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.
Caution
Use of fuel that does not comply to EN 228 or equivalent can lead to
deposits or engine damage.
Caution
Use of fuel with a lower octane
rating than the lowest possible
rating could lead to uncontrolled combustion and engine damage.
The engine-specific requirements
regarding octane rating are given in
the engine data overview 3 224. A
country-specific label at the fuel filler
flap can supersede the requirement.
Fuel additive
Fuel should contain detergent
additives that help prevent engine
and fuel system deposits from
forming. Clean fuel injectors and
intake valves will allow the emission
control system to work properly. In
certain countries fuel does not
contain sufficient quantities of
additive to keep fuel injectors and
intake valves clean. In these
countries a fuel additive is required for
some engines to make up for this lack
of detergency. Only use fuel additive
approved for the vehicle.
Adding fuel additive to the filled fuel
tank is required at least every 15,000 km or after one year, whichever
occurs first. For further information,
contact your workshop.
Prohibited fuels
Fuels containing oxygenates such as
ethers and ethanol, as well as
reformulated fuel, are available in
some cities. If these fuels comply with the previously described
specification, then they are
acceptable to use. However, E85(85% ethanol) and other fuels
containing more than 15% ethanol
must be used only in FlexFuel
vehicles.Caution
Do not use fuel containing
methanol. It can corrode metal
parts in the fuel system and also
damage plastic and rubber parts.
This damage would not be
covered by the vehicle warranty.
Some fuels, mainly high octane
racing fuels, can contain an octane
enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). Do not use fuels or fuel additives with MMT as they can
reduce spark plug life and affect
emission control system
performance. The malfunction
indicator light Z may illuminate 3 93.
If this occurs, seek the assistance of
a workshop.
