DRIVER SUPPORT

IMPORTANT
Under certain circumstances, the function
is unable to find parking spaces - one rea-
son for this may be the fact that there is
interference with the sensors from external
sound sources which emit the same ultra-
sound frequencies as those with which the
system works.
Examples of such sources include horns,
wet tyres on asphalt, pneumatic brakes
and exhaust noises from motorcycles etc.
NOTE
Dirt, ice and snow covering the sensors
will reduce their function and may prevent
measurement.
Driver responsibility
The driver should bear in mind that the func-
tion is an aid – not an infallible, fully-automatic
function. The driver must therefore be pre-
pared to interrupt a parking step.
121 "Approved tyres" refers to tyres of the same type and make as those fitted new on delivery from the factory.

There are also a few details to bear in mind
while parking, e.g.:
The driver is always responsible for deter-
•
mining whether the space selected by the
function is suitable for parking.
Do not use the function if snow chains or
•
a spare wheel are fitted.
Do not use the function if cargo items are
•
protruding from the car.
Heavy rain or snow may cause the system
•
to measure the parking space incorrectly.
During the search and check-measure-
•
ment of the parking space, the function
may miss objects positioned deep in the
parking space.
Parking spaces on narrow streets are not
•
always feasible, since the space required
for manoeuvring may not be sufficient.
Use approved tyres 121 with the correct tyre
•
pressure - this affects the ability of the
function to park the car.
The function bases itself on the locations
•
of vehicles already parked nearby – if they
are inappropriately parked, your own car's
tyres and wheel rims may be damaged by
contact with the kerb.
Perpendicular parking spaces may be
•
missed or offered unnecessarily if one
parked car is protruding more than other
parked cars.
The function is designed for parking on
•
straight streets – not sharp curves or
bends. For this reason, make sure the car
is parallel to the potential parking spaces
when the function measures the space.
