Arming and disarming
When you lock or unlock the vehicle, either with 
the remote control or at the door lock, the alarm 
system is armed or disarmed at the same time.
You can open the luggage compartment lid 
even when the alarm system is armed, by 
pressing the   button on the remote control, 
refer to page28. The lid is locked and moni-
tored again as soon as you close it.
Panic mode*
You can trigger the alarm system if you find 
yourself in a dangerous situation:
Press the   button for at least three seconds.
To switch off the alarm: press any button.
Switching off an alarm
>Unlock the car with the remote control, refer 
to page27.
>Insert the remote control all the way into the 
ignition lock.
Indicator lamp displays
>The indicator lamp under the inside rear-
view mirror flashes continuously: the sys-
tem is armed.
>The indicator lamp flashes after locking: 
doors, hood or luggage compartment lid are 
not properly closed. Even if you do not close 
the alerted area, the system begins to mon-
itor the remaining areas, and the indicator 
lamp flashes continuously after approx. 
10 seconds. The interior m o t i o n  s e n s o r  a n d  
the tilt alarm sensor are not activated.>The indicator lamp goes out after unlocking: 
your vehicle has not been disturbed while 
you were away.
>If the indicator lamp flashes after unlocking 
until the remote control is inserted in the 
ignition, but for no longer than approx. 
5 minutes: your vehicle has been disturbed 
while you were away.
Tilt alarm sensor
The tilt of the vehicle is monitored. The alarm 
system reacts, e.g. to attempts to steal a wheel 
or tow the vehicle.
Interior motion sensor
Coupe
In order for the interior motion sensor to func-
tion properly, the windows and glass roof must 
be completely closed
*.
Convertible
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. The 
alarm can be triggered unintentionally by falling 
objects such as leaves, refer to Avoiding unin-
tentional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor 
may be switched off at the same time. This pre-
vents unintentional alarms, e.g. in the following 
situations:
>In duplex garages
>During transport on car-carrying trains, 
boats/ships or on a trailer
>When animals are to remain in the vehicle
Switching off tilt alarm sensor and 
interior motion sensor
Press the   button on the remote control 
again as soon as the vehicle is locked.
The indicator lamp lights up briefly and then 
flashes continuously. The tilt alarm sensor and

Park Distance Control PDC*
The concept
The PDC assists you with maneuvering in tight 
parking spaces. Acoustic signals and a visual 
indicator
 warn you of the presence of an object 
behind your vehicle. To measure the distance, 
there are four ultrasonic sensors in either 
bumper.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not 
sound until an object is approx. 24 in/60 cm 
from the corner sensors, or approx. 5 ft/1.50 m 
from the center sensors.
PDC is a parking aid that can indicate 
objects when they are approached 
slowly, as is usually the case when parking. 
Avoid approaching an object at high speed, oth-
erwise physical circumstances may lead to the 
system warning being issued too late.<
Switching on automatically
With the engine running or the ignition switched 
on, the system is activated approx. 1 second 
after you engage reverse gear or selector lever 
or transmission position R. Wait this short 
period before driving.
Switching off automatically
After approx. 165 ft/50 m of driving or above 
approx. 20 mph/approx. 30 km/h, the system 
switches off and the LED goes out.
Signal tones
When nearing an object, its position is indicated 
correspondingly by an interval tone. As the dis-
tance between vehicle and object decreases, 
the intervals between the tones become 
shorter. If the distance to the nearest object 
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
An interval tone is interrupted after approx. 
3seconds>if you remain in front of an object that has 
been detected by only one of the corner 
sensors
>if you are driving parallel to a wall.
Malfunction
The indicator lamp in the instrument 
cluster comes on. PDC is malfunc-
tioning. A message appears on the 
Control Display. Have the system checked.
To avoid this problem, keep the sensors clean 
and free of ice or snow in order to ensure that 
they will continue to operate effectively. When 
using a high-pressure cleaner, do not spray the 
sensors for extended periods of time and only 
from a distance of at least 4 in/10 cm.
PDC with visual warning
The approach of the vehicle to an object is 
shown on the Control Display. Objects that are 
farther away are displayed on the Control Dis-
play before a signal tone sounds. The display 
appears on the Control Display as soon as PDC 
is activated.
System limitations
Even with PDC, final responsibility for 
estimating the distance between the 
vehicle and any obstructions always remains 
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can 
no longer be detected. The system is also sub-
ject to the physical limits that apply to all forms 
of ultrasonic measurement, such as those 
encountered with trailer towbars and hitches, 
thin or wedge-shaped objects, etc. Low objects 
that have already been displayed, e.g. curbs, 
can disappear again from the detection area of 
the sensors before or after a continuous tone 
sounds. Higher, protruding objects, e.g. ledges, 
cannot be detected. Therefore, always drive 
cautiously, otherwise there is a risk of personal 
injury or property damage.

Cargo loading
To avoid loading the tires beyond their 
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage 
develops inside the tires. This can ultimately 
result in a sudden blow-out.<
Make sure that no liquids are spilled or 
leak from their containers in the cargo 
bay, as this could result in damage to the vehi-
cle.<
Determining loading limit
1.Locate the following statement on your 
vehicle's placard
*:
The combined weight of occupants 
and cargo should never exceed 
XXX kg or YYY lbs. Otherwise, overloading 
can result in damage to the vehicle and 
unstable driving conditions.<
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-lb. 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, part of 
the load from your trailer will be transferred 
to your vehicle. Consult the manual for 
transporting a trailer to determine how this 
may reduce the available cargo and luggage 
load capacity of your vehicle.
Load
The permissible load is the total of the weight of 
occupants and cargo/luggage. The greater the 
weight of the occupants, the less cargo/lug-
gage can be transported.
Stowing cargo
>Position heavy objects as low and as far for-
ward as possible, ideally directly behind the 
respective seat backrests.
>Cover sharp edges and corners.
>For very heavy cargo when the rear seat is 
not occupied, secure each safety belt in the 
opposite buckle.
