294 Driving and parking
When Active Parking Assist is activated, the turn
signal indicators are activated based on the cal‐
culated path of your vehicle.
When you are entering or exiting a parking
space, the procedure is assisted by acceleration,
braking, steering and gear changes.
Active Parking Assist is only an aid. It is not a
substitute for your attention to the surroundings.
The responsibility for safe manoeuvring and
parking remains with you. Make sure that no
persons, animals or objects etc. are in the
manoeuvring range.
Active Parking Assist will be cancelled in the fol‐
lowing situations:
Parking Assist PARKTRONIC is deactivated.

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 goods vehicles, or
the borders of parking spaces, are not detected
during measurement of the parking space. These
are also then not taken into account when calcu‐
lating the parking procedure. In some circum‐
stances, 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 fitted.
R
When a trailer or bicycle rack is attached.
R
Directly after a tyre change or when spare
R
tyres are fitted.
If the tyre pressure is too low or too high.
