Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the trunk lid is 
opened
>To movements inside the vehicle: interior 
motion sensor, refer to page33
>When the car's inclination changes, for 
instance if an attempt is made to jack it up 
and steal the wheels or to raise it prior to 
towing away: tilt alarm sensor, refer to 
page33
>When there has been an interruption of 
power supply from the battery
Depending on the market-specific version, the 
alarm system briefly signals unauthorized entry 
attempts by:
>An acoustic alarm
>Switching on
* the hazard warning flashers
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 trunk lid using the   button 
of the remote control even if the alarm system is armed, refer to page28. The lid is locked and 
monitored again as soon as it is closed.
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, or
>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 trunk lid are not properly 
closed. Even if you do not close the alerted 
area, the system begins to monitor the 
remaining areas, and the indicator lamp 
flashes continuously after approx. 
10 seconds. The interior motion sensor and 
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 convertible top is 
open. An alarm can be triggered unintentionally 
by falling objects such as leaves, refer to Avoid-
ing unintentional 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 
the interior motion sensor are switched off until 
the next time the vehicle is unlocked and subse-
quently locked again.
Comfort Access*
Comfort Access enables you to enter your vehi-
cle without needing to hold the remote control 
in your hand. All you need to do is wear the 
remote control close to your body, e.g. in your 
jacket pocket. The vehicle detects the corre-
sponding remote control within the immediate 
vicinity or in the passenger compartment.
Comfort Access supports the following func-
tions:
>Unlocking/locking the vehicle
>Unlocking the trunk lid separately
>Engine starting
>Convenient closing
Functional requirement
>The vehicle or the trunk lid can only be 
locked when the vehicle detects that the 
remote control currently in use is outside of 
the vehicle.
>The vehicle cannot be locked or unlocked 
again until after approx. 2 seconds.
>The engine can only be started when the 
vehicle detects that the remote control cur-
rently in use is inside the vehicle.
Comparison to the standard remote 
control
In general, there is no difference between using 
Comfort Access or pressing the buttons on the 
remote control to carry out the functions men-
tioned above. You should therefore first famil-
iarize yourself with the instructions on opening 
and closing starting on page26.
Special features regarding the use of Comfort 
Access are described below.
If you notice a brief delay while opening or 
closing windows, the glass roof or the 
convertible top, the system is checking whether 
a remote control is inside the vehicle. Please 
repeat the opening or closing procedure, if nec-
essary.<

Intermittent wipe or rain sensor*
If the car is not equipped with a rain sensor, the 
intermittent-wipe time is a preset.
If the car is equipped with a rain sensor, the time 
between wipes is controlled automatically and 
depends on the intensity of the rainfall. The rain sensor is mounted on the windshield, directly in 
front of the interior rearview mirror.
Activating intermittent wipe or rain 
sensor
Press the button, arrow3. The LED in the but-
ton lights up.
Setting speed for intermittent wipe or 
sensitivity of the rain sensor

Deactivate the rain sensor before enter-
ing an automatic car wash. Failure to do 
so could result in damage caused by undesired 
wiper activation.<
Cleaning windshield and headlamps*
Pull the lever, arrow 4.
Washer fluid is sprayed onto the windshield and 
the wipers are operated for a short time.
When the vehicle lighting system is switched 
on, the headlamps are cleaned at regular and 
appropriate intervals.
Do not use the washers if there is any 
danger that the fluid will freeze on the 
windshield. If you do, your vision could be 
obscured. Antifreeze should therefore be 
added to the fluid, refer to Washer fluid. 
Do not use the washers when the washer fluid 
reservoir is empty; otherwise, you will damage 
the washer pump.<

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. Four ultrasonic sensors in 
the bumper measure the distance.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not 
sound until an object is approx. 2 ft/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 after approx. second 
when you engage reverse gear or move the 
automatic transmission selector lever to 
position R. Wait this short period before driving.
Switching off automatically
After approx. 55 yd/50 m of driving or above 
approx. 20 mph/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 stop 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 1 ft/30 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. Loud sound sources out-
side or inside the car can drown out the PDC 
signal. Therefore, always drive cautiously; oth-
erwise, there is a risk of personal injury or prop-
erty damage.<

Roadside parking lamps, left or right*
There is an additional option of switching on the 
lamps on the side of the car facing the road 
when parked.
Switching on
After parking the vehicle, press the lever up or 
down beyond the pressure point for approx. 
1 second, arrow 3.
The roadside parking lamps drain the bat-
tery. Therefore, do not leave them on for 
unduly long periods of time; otherwise, the bat-
tery might not have enough power to start the 
engine.<
Switching off
Press the lever in the opposite direction to the 
pressure point, arrow 3.
High-beam assistant*
The concept
This system automatically switches the high 
beams on and off. The procedure is controlled 
by a sensor on the front of the interior rearview 
mirror. The assistant ensures that the high 
beams are switched on whenever the traffic sit-
uation allows. It handles this task for you and 
gives you the benefit of the best possible view. 
You can intervene at any time and switch the 
high beams on and off as usual.
Activating the system
1.Turn the light switch to position3, refer to 
page91.
2.With the low beams switched on, briefly 
push the turn signal/high beam lever in the 
direction of the high beam.
The indicator lamp in the instrument 
cluster lights up when the high beams 
are activated. The system automati-
cally switches from high beams to low beams 
and vice versa in response to oncoming traffic, 
traffic ahead of you, and adequate ambient 
lighting, e.g. on city streets.
Switching the high beams on and off 
manually
Whenever you wish, or when the situation 
requires, you can intervene:
>If the high-beam assistant switches on the 
high beams, but you would like to drive with 
the low beams, simply switch off the high 
beams using the turn signal/high beam 
lever. This deactivates the high-beam 
assistant. 
To reactivate the system, briefly push the 
turn signal/high beam lever toward the high 
beams again.
>If the high-beam assistant switches on the 
low beams, but you would like to drive with 
the high beams, switch on the high beams 
as usual. This deactivates the system and 
the high beams need to be switched off 
manually, if necessary. 

Lamps
94 To reactivate the system, briefly push the 
turn signal/high beam lever toward the high 
beams again.
>Use the headlamp flasher as usual with the 
low beams switched on.
System limitations
The high-beam assistant cannot serve as 
a substitute for the driver's personal judg-
ment of when to use the high beams. Therefore, 
manually switch off the high beams in situations 
where this is required to avoid a safety risk.<
The system is not fully functional in situations 
such as the following, and driver intervention 
may be necessary:
>In very unfavorable weather conditions, 
such as fog or heavy precipitation
>In detecting poorly-lit road users, such as 
pedestrians, cyclists, horseback riders and 
wagons; when driving close to train or ship 
traffic; and at animal crossings
>In tight curves, on hilltops or in depressions, 
in cross traffic or half-obscured oncoming 
traffic on highways
>In poorly lit towns and cities and in the pres-
ence of highly reflective signs
>At low speeds
>When the windshield in front of the interior 
rearview mirror is fogged over, dirty or cov-
ered with stickers, etc.
>If the sensor is dirty. Clean the sensor on 
the front of the interior rearview mirror using 
a cloth moistened with a small amount of 
glass cleaner.

Fog lamps*
To switch on/off, press the button.
The parking lamps or low beams must 
be switched on for the fog lamps to 
operate. The green indicator lamp in 
the instrument cluster lights up whenever the 
fog lamps are on.
The fog lamps are switched off while you acti-
vate the headlamp flasher or switch on the high 
beams.
If the automatic headlamp control is acti-
vated, the low beams will come on auto-
matically when you switch on the fog lamps.<
