Basic notes on parking assistsystems9 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 must 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.
Note
The parking assist system can be
activated and deactivated by
changing the settings in the
Info-Display.
Vehicle personalisation 3 104.
Note
The parking assist system
automatically detects factory-fitted
towing equipment. It is deactivated
when the connector is plugged in.
It is possible that the sensor detects a non-existing object (echo
disturbance) caused by external acoustical or mechanic
disturbances.
Advanced parking assist system
may not respond to changes in the
parking space after initiating a
parallel parking manoeuvre.
Note
After use the advanced parking
assist requires a calibration. For
optimal parking guidance, a driving
distance of at least 35 km, including
a number of bends, is required.
Side blind spot alert The Side blind spot alert system
detects and reports objects on either
side of the vehicle, within a specified
"blind spot" zone. The system alerts
visually in each exterior mirror, when
detecting objects that may not be
visible in the interior and exterior
mirrors.
The system's sensors are located in
the bumper on the left and right side
of the vehicle.
Driving and operating1659Warning
Side blind spot alert does not
replace driver vision.
The system does not detect: ■ Vehicles outside the side blind zones which may be rapidly
approaching.
■ Pedestrians, cyclists or animals.
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
When the system detects a vehicle in the side blind zone while driving
forward, either while passing a
vehicle or being passed, an amber warning symbol B will illuminate in
the relevant exterior mirror. If the
driver then activates the turn signal,
the warning symbol B starts flashing
amber as a warning not to change
lanes.
Note
If the passing vehicle is at least
10 km/h faster than the passed
vehicle, the warning symbol B in the
relevant exterior mirror will not
illuminate.
Side blind spot alert is active from
speeds of 10 km/h up to 140 km/h.
Driving faster than 140 km/h
deactivates the system, indicated by
low lighting warning symbols B in
both exterior mirrors. Reducing the speed again will extinguish the
warning symbols. If a vehicle is then
detected in the blind zone, the
warning symbols B will illuminate as
normal on the relevant side.
When the vehicle is started, both exterior mirror displays will briefly
come on to indicate that the system is operating.
The system can be activated or
deactivated in the menu Settings in
the Info-Display, vehicle

The tyre pressure information label
on the left door frame indicates the
original equipment tyres and the
correspondent tyre pressures.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 234.
2. Identify the respective tyre.
The tyre pressure tables show all possible tyre combinations 3 239.For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition. After adjusting tyre
pressure switch on ignition and select the relevant setting on the page Tyre
load on the Driver Information Centre,
3 96.
Tyre pressure monitoring
system The tyre pressure monitoring system
(TPMS) checks the pressure of all
four wheels once a minute when
vehicle speed exceeds a certain limit.Caution
Tyre pressure monitoring system
warns only about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Note
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
