Indicator lamp on the interior rearview
mirror▷The indicator lamp flashes briefly every
2 seconds:
The system is armed.▷The indicator lamp flashes after locking:
The doors, hood or trunk lid is not closed
properly, but the rest of the vehicle is se‐
cured.
The indicator lamp flashes continuously af‐
ter approx. 10 seconds. The interior motion
sensor and tilt alarm sensor are not active.▷The indicator lamp goes out after unlocking:
The vehicle has not been tampered with.▷If the indicator lamp flashes after unlocking
until the remote control is inserted in the ig‐
nition, but for no longer than approx. 5 mi‐
nutes:
An alarm has been triggered.
Tilt alarm sensor
The tilt of the vehicle is monitored.
The alarm system responds in situations such
as attempts to steal a wheel or tow the car.
Interior motion sensor
The interior of the car is monitored up to the
height of the seat cushions. Thus the alarm sys‐
tem is activated together with the interior motion
sensor even if the hardtop is open. An alarm can
be triggered unintentionally by falling objects
such as leaves, refer to Avoiding unintentional
alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
can be switched off together, such as in the fol‐
lowing situations:▷In duplex garages.▷During transport on car-carrying trains, at
sea or on a trailer.▷When animals are to remain in the vehicle.
Switching off the tilt alarm sensor and
interior motion sensor
Press the remote control button again
within 10 seconds after the vehicle is locked.
The indicator lamp lights up for approx. 2 sec‐
onds and then continues flashing.
The tilt alarm sensor and interior motion sensor
remain switched off until the vehicle is locked
again.
Power windows
General information Take the remote control with you
Take the remote control with you when
leaving the vehicle so that children, for example,
cannot operate the power windows and injure
themselves.◀
Danger of pinching
Monitor the closing process and make
sure that the closing path of the window is clear;
otherwise, injuries may result.◀

Park Distance Control PDC
The concept
PDC supports you when parking.
Objects in front of or behind your vehicle that
you are approaching slowly are indicated by
acoustic signals.
Measurement
Measurements are made by ultrasound sensors
in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:▷By the front sensors and two rear corner
sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx. 5 ft/
1.50 m.
System limits
Check the traffic situation as well
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion. Check the traffic situation around the vehi‐
cle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside of the PDC detection range.
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal
tone.◀
Avoid driving quickly with PDC
Avoid approaching an object quickly.
Avoid driving away quickly while PDC is not yet
active.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
Limits of ultrasonic measurement
The detection of objects can reach the physical
limits of ultrasonic measurement, for instance:▷With tow bars and trailer hitches.▷With thin or wedge-shaped objects.▷With low objects.▷With objects with corners and sharp edges.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before or
after a continuous tone sounds.
High, protruding objects such as ledges may not
be detected.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷In heavy rain.▷When sensors are very dirty or covered in
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷In large buildings with right angles and
smooth walls, e.g., in underground garages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
Switching on automatically
Engage reverse gear with the engine running or
the ignition switched on.
Switching off automatically when
driving forward
The system switches off when a certain distance
or speed is exceeded.
Switch on the system again if necessary.

Determining the load limit1.Locate the following statement on your ve‐
hicle’s placard:▷The combined weight of occupants and
cargo should never exceed XXX kg or
YYY lbs. Otherwise, damage to the ve‐
hicle and unstable driving situations may
result.2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.3.Subtract the combined weight of the driver
and passengers from XXX kilograms or YYY
pounds.4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
1,400 lbs and there will be five 150 lbs pas‐
sengers in your vehicle, the amount of avail‐
able cargo and luggage load capacity is
650 lbs: 1,400 lbs minus 750 lbs = 650 lbs.5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in Step 4.6.If your vehicle will be towing a trailer, load
from your trailer will be transfered to your
vehicle. Consult the manual for transporting
a trailer to determine how this may reduce
the available cargo and luggage load ca‐
pacity of your vehicle.Load
The maximum load is the sum of the weight of
the occupants and the cargo.
The greater the weight of the occupants, the
less cargo that can be transported.
Stowing cargo
Trunk
▷Heavy cargo: stow as far forward and as low
as possible, ideally directly behind the trunk
separating wall.▷Cover sharp edges and corners.
Loading with the hardtop open
Before opening the hardtop, fold down the
cargo area partition and make sure the cargo
area is loaded correctly; otherwise, parts of the
hardtop could be damaged.◀
Fold down the cargo area partition, refer to
page 34.
