Caution: Parking spaces that are partially occupied may be
measured incorrectly. Examples of partially occupied parking
spaces can be trailer draw bars, over grown parking spaces or
incorrect measurement due to heavy rain or snow. Care
should be taken to make sure the space is clear.
Caution: Active Park Assist will not be able to detect
objects above the sensor height range when a parking space
is measured. These object will not be included when the
parking procedure is calculated. Active Park Assist should not
be used around objects such as overhanging loads or tail
sections of goods vehicles.
Active Park Assist can be cancelled at any time by manually
controlling the steering wheel.
Active Park Assist may also display parking spaces that are not
suitable such as prohibited parking zones, driveways or
unsuitable road surfaces.
Active Park Assist should only be used for roads that are
parallel or at right angles to the direction of travel and on the
same road level. The system should not be used for measuring
spaces on bends or on raised footpaths.

Driving
Parking Space Detection
Active Park Assist operates at speeds of up to approximately
22 mph (35 km/h).
Active Park Assist is activated automatically when driving
forwards and independently locates and measures parking spaces
on both sides of the vehicle.
At speeds below 18 mph (30 km/h),
instrument cluster. When a parking space has been detected that
the vehicle will fit into, a left or right arrow will show which side
of the vehicle the space is on.
Active Parking Assist will only detect parking spaces that are:
• parallel to the direction of travel and at least 1.5 m (5 ft) wide
and 1 m (3.3ft) longer than your vehicle.
• at right angles to the direction of travel and at least 1 m wider
than your vehicle.
Active Park Assist is not able to measure the depth of a
parking space if it is at right angles to the vehicle. You must judge
if your vehicle will fit in the parking space.
The system automatically determines if the parking space is
parallel or at right angles to the direction of travel.
A parking space is displayed while you are driving past it, until
you are approximately 15 m (50 ft) away from it.
