Brake force display
The concept
▷During normal brake application, the outer
brake lamps light up.▷During heavy brake application, the inner
brake lamps light up in addition.
Active Protection
General information
The Active Protection safety package consists
of systems that are independent of each other:
▷Attentiveness assistant.▷PreCrash▷PostCrashAttentiveness assistant
The concept The system can detect increasing lack of alert‐
ness or fatigue of the driver during long, mo‐
notonous journeys, for example, on highways.
In this situation, it is recommended that the
driver take a break.
Note Personal responsibility
The system cannot act as a substitute for
the personal assessment of one's physical
state and may not detect an increasing lack of
alertness or fatigue or may not detect it cor‐
rectly. Therefore, make sure that the driver is
rested and alert; otherwise, risks may be de‐
tected too late and an accident be caused as a
result.◀
Function
The system is activated each time the engine
is started and cannot be switched off.
After travel has begun, the system is trained
about the driver, so that increasing lack of
alertness or fatigue can be detected.
This procedure takes the following criteria into
account:▷Personal driving style, for example, steer‐
ing behavior.▷Driving conditions, for example, length of
trip.
Starting at approximately 43 mph/70 km/h, the
system is active and can display a recommen‐
dation to take a break.
Break recommendation
If the driver becomes increasingly less alert or
fatigued, a message is displayed in the Control
Display with the recommendation to take a
break.
A recommendation to take a break is displayed
only once during an uninterrupted trip.

System limits
The cameras capture a maximum range of
330 ft/100 m.
Parking assistantThe concept
This system assists the driver in parking paral‐
lel to the road.
Ultrasound sensors measure parking spaces
on both sides of the vehicle.
The parking assistant calculates the best pos‐
sible parking line and takes control of steering
during the parking procedure.
When parking, also take note of the visual and
acoustic information issued by the PDC and
the parking assistant and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 142.
Hints Personal responsibility
The parking assistant does not relieve
the driver of responsibility for the vehicle dur‐
ing the parking procedure.
Watch the parking space and parking proce‐
dure closely and intervene if necessary; other‐
wise, there is the danger of an accident.◀
Changes to the parking space
Changes to the parking space after it was
measured are not taken into account by the
system.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the danger of an acci‐
dent occurring.◀
Transporting loads
Loads that extend beyond the perimeter
of the vehicle are not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the danger of an acci‐
dent occurring.◀
Curbs
The parking assistant may steer the vehi‐
cle over or onto curbs.
Therefore, always be alert and ready to inter‐
vene; otherwise, the wheels, tires, or the vehi‐
cle may become damaged.◀
An engine that has been switched off by the
Auto Start Stop function is restarted automati‐
cally when the parking assistant is activated.
Requirements
For measuring parking spaces▷Maximum speed while driving forward ap‐
prox. 22 mph/35 km/h.▷Maximum distance to row of parked vehi‐
cles: 5 ft/1.5 m.
Suitable parking space
▷Gap between two objects with a minimum
length of approx. 5 ft/1.5 m.▷Minimum length of the gap: own vehicle's
length plus approx. 4 ft/1.2 m.▷Minimum depth: approx. 5 ft/1.5 m.
For parking procedure
▷Closed doors.▷Parking brake released.Seite 150ControlsDriving comfort150

the convertible top in the convertible top
well while the top is wet or frozen.▷Remove water stains that may neverthe‐
less have appeared on the headliner using
a microfiber cloth and an interior cleaner.▷When the vehicle is parked in enclosed
areas for lengthy periods, ensure that the
area is well ventilated.▷If possible, park the vehicle in the shade to
protect it from intensive solar radiation so
that color, rubber and fabric are not af‐
fected.▷Remove bird droppings immediately as
their corrosive effect will otherwise attack
the convertible top and damage the rubber
seals.▷Hard to remove tree sap or bird droppings
can be removed from the convertible top
with special tree sap remover and a soft
brush.
Do not use spot remover
Do not use spot remover, paint thinner,
solvent, gasoline, or similar products to re‐
move spots on the convertible top. These
products may destroy the rubber coating. In‐
correct care and cleaning may cause the
convertible top and its seams to become
leaky.◀
To remove heavy soiling, especially for light
colored convertible tops, use a special
convertible top cleaner.
Proceed as follows:
1.Spray the convertible top with the
convertible top cleaner.2.Make the convertible top cleaner foam up
using a well saturated sponge, moving it in
circular motions.3.Finish washing the vehicle in the car wash
or rinse with ample amounts of water.
Otherwise, follow the instructions for use from
the manufacturer.
Treat the convertible top with an impregnating
agent after it has been washed three to five
times.
Suitable cleaners and car products can be ob‐
tained from the service department.
Leather care
Remove dust from the leather often, using a
cloth or vacuum cleaner.
Otherwise, particles of dust and road grime
chafe in pores and folds, and lead to increased wear and premature degradation of the leather
surface.
To guard against discoloration, such as from
clothing, provide leather care roughly every
two months.
Clean light-colored leather more frequently be‐
cause soiling on such surfaces is substantially
more visible.
Use leather care products; otherwise, dirt and
grease will gradually break down the protective
layer of the leather surface.
Suitable care products are available from the
service center.
Upholstery material care Vacuum regularly with a vacuum cleaner.
If they are very dirty, e.g., beverage stains, use
a soft sponge or microfiber cloth with a suita‐
ble interior cleaner.
Clean the upholstery down to the seams using
large sweeping motions. Avoid rubbing the
material vigorously.
Damage from Velcro® fasteners
Open Velcro® fasteners on pants or
other articles of clothing can damage the seat
covers. Ensure that any Velcro® fasteners are
closed.◀Seite 223CareMobility223
