System limits
If the exterior lighting is malfunctioning, Active
Parking Assist is not available.
Objects located above or below the detection
range of the sensors, e.g. overhanging loads,
overhangs or loading ramps of trucks, or the bor‐
ders of parking spaces, are not detected during
measurement of the parking space. These are
also then not taken into account when calculat‐
ing the parking procedure. In some circumstan‐
ces, Active Parking Assist may therefore guide
you into the parking space incorrectly.
& WARNING Risk of accident due to
objects located above or below the
detection range of Active Parking Assist
If there are objects above or below the
detection range, the following situations may
arise:
Active Parking Assist may steer too early.
R
The vehicle may not stop in front of these
R
objects.
This could cause a collision.
In these situations, do not use Active
#
Parking Assist.
Extreme weather conditions, such as snow or
heavy rain, may lead to a parking space being
measured inaccurately. Parking spaces that are
partially occupied by trailer drawbars might not
be identified as such or be measured incorrectly.
Only use Active Parking Assist on level, high-grip
ground.
Do not use Active Parking Assist in the following
situations:
In extreme weather conditions such as ice,
R
packed snow or in heavy rain.
When transporting a load that protrudes
R
beyond the vehicle.
On steep uphill or downhill gradients of more
R
than approximately 15%.
When snow chains are installed.
R
When a trailer or bicycle rack is attached.
R
Directly after a tire change or when spare
R
tires are installed.
If the tire pressure is too low or too high.
R
If the suspension is out of alignment, e.g.
R
after bottoming out on a curb.
Active Parking Assist may also display parking
spaces that are not suitable for parking, such as:
Parking spaces where parking is prohibited.
R
Parking spaces on unsuitable surfaces.
