Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the
front bumper and four sensors in the rear
bumper. PARKTRONIC indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a
replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting
aparking space. When
maneuvering, parking or pulling out of a
parking space, make sure that there are no
persons, animals or objects in the area in
which you are maneuvering.
! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.

car wash, the compressed-air brakes on a 172

Detectin gparking spaces Objects located above the height range of
Active Parking Assist willn ot be detected
when the parking space is measured. These
are not taken into account when the parking procedure is calculated
,e.g. overhanging
loads, tail sections or loading ramps of goods

There is arisk of an accident.
In such cases, use atow bar. Before towing,
make sure that the steering moves freely. G
WARNING
If the weight of the vehicle to be towed or tow-
started is greater than the permissible gross
weight of your vehicle:
R the towing eye could detach itself
R the vehicle/trailer combination could
rollover.
There is arisk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the
permissible gross weight of your vehicle.

applicable) must not exceed the specified
value.

Step-by-step instructions The following steps have been developed as
required of all manufacturers under Title 49,
Code of U.S.F
ederal Regulations, Part 575
pursuant to the "National Traffic and Motor
Vehicle Safet yActof 1966".
X Step 1: Locatethe statement "The
combined weight of occupants and cargo
should never exceed XXX kg or XXX lbs." on
your vehicle’s Tire and Loading Information
placard.
X Step 2: Determine the combined weight of
the driver and passengers that will be riding
in your vehicle.
X Step 3: Subtract the combined weight of
the driver and passengers from XXX
kilograms or XXX lbs. 324
Loading thev
ehicleWheels and tires

X
Step 4: The resulting figure equalst he
available amount of cargo and luggagel oad
capacity. For example, if the "XXX" amount
equals1 400 lbs and there are five
occupants in the vehicle each with aweight
of 150 lbs, the amount of available cargo
and luggagel oad capacity is 650 lbs (1400
000F 750 (5 x150) =650 lbs).
X Step 5: Determine the combined weight of
luggagea nd cargo being loaded on the
vehicle. That weight may not safely exceed
the available cargo and luggagel oad
capacity calculated in step 4.
X Step 6(if applicable): If your vehicle will
be towing atrailer, load from your trailer
will be transferred to your vehicle. Refer to
this Operator's Manual to determine how
this reduces the available cargo and
luggagel oad capacity of your vehicle
