Central locking system
The concept
The central locking system functions when the 
driver's door is closed.
The system simultaneously engages and 
releases the locks on the following:
>Doors
>Trunk lid
>Fuel filler flap
Operating from outside
>Via the remote control
>Via the door lock
*
>In cars with Comfort Access*, via the han-
dles on the driver's and front passenger 
doors
In addition, if the remote control is used, the 
welcome lamps
*, interior lamps and the door's 
courtesy lamps
* are switched on or off. The 
alarm system
* is also armed or disarmed.
For further details on the alarm system
*, refer 
to page32.
Operating from inside
By means of the button for central locking, refer 
to page30.
In the event of a sufficiently severe accident, the 
central locking system unlocks automatically. In 
addition, the hazard warning flashers and inte-
rior lamps come on.
Opening and closing:
Using the remote control
Persons or animals in a parked vehicle 
could lock the doors from the inside. You 
should therefore take the remote control with 
you when you leave the vehicle so that the latter 
can be opened from outside.<
Convertible: to operate the convertible 
top with the remote control, the doors and 
trunk lid must be closed and the cargo area par-
tition must be folded down and engaged on 
both sides. Refer also to page40.<
Unlocking
Press the   button.
The interior lamps, the courtesy lamps
* and the 
welcome lamps come on.
Setting unlocking characteristics
You can set whether only the driver's door or 
the entire vehicle is to be unlocked when the 
button is pressed for the first time.

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.< 

Technology for driving comfort and safety
82 >When driving uphill on snow-covered roads, 
in slush or on unplowed, snow-covered 
roads
>When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>When driving with snow chains
Activating DTC
Press the button; the indicator lamps for DTC in 
the instrument cluster come on.
For better control
If the indicator lamp flashes: 
DTC is regulating the drive and braking 
forces.
If the indicator lamps are on: 
DTC has been activated.
Deactivating DTC
Press the button again; the DTC indicator 
lamps in the instrument cluster go out.
Drive-off assistant
The drive-off assistant enables you to drive off 
smoothly on uphill gradients. It is not necessary 
to use the parking brake for this.
1.Hold the car in place by depressing the 
brake.
2.Release the brake and drive off without 
delay.
The drive-off assistant holds the car in 
place for approx. 2 seconds after the 
brake is released. Drive off without delay after 
releasing the brake. Otherwise, the drive-off assistant will no longer hold the car in place 
after approx. 2 seconds and the car will start to 
roll backwards.<
Flat Tire Monitor FTM*
The concept
The system does not measure the actual infla-
tion pressure in the tires.
The system detects a tire pressure loss due to 
speed comparisons among the individual 
wheels as you drive.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed 
of the affected wheel. The system detects this 
and reports it as a flat tire.
Functional requirement
The system has to have been initialized at the 
correct inflation pressure; otherwise, a reliable 
reporting of a flat tire is not assured.
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed, 
reinitialize the system.
System limitations
It is impossible to provide advance warn-
ing of sudden, severe tire damage caused 
by outside influences.<
The system will not detect a natural, uniform 
pressure loss in all four tires. Therefore you 
should check the inflation pressure regularly.
In the following situations, the system could be 
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip 
in the drive wheels, high lateral acceleration
>Driving with snow chains
*
Status display
The current status of the Flat Tire Monitor can 
be displayed on the Control Display, e.g. 
whether or not the FTM is active.

When you open the driver's door with the igni-
tion switched off, the exterior lighting is auto-
matically switched off if the light switch is in 
position 0, 2 or 3.
Switch on the parking lamps if necessary, 
switch position 1.
Parking lamps
In switch position1, the front, rear and side 
vehicle lighting is switched on. You can use the 
parking lamps for parking.
The parking lamps will discharge 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. It is preferable to switch on the left-
hand or right-hand roadside parking lamps, 
refer to page93.<
Low-beam headlamps
The low beams light up when the light switch is 
in position 2 and the ignition is on.
Automatic headlamp control*
When the switch is in position3, the low beams 
are switched on and off automatically depend-
ing on ambient light conditions, e.g. in a tunnel, 
in twilight, or if there is precipitation. The adap-
tive light control
* is active. The LED next to the 
symbol is illuminated when the low beams are 
on. You can also activate the daytime running 
lights, refer to page92. In the situations 
described above, the lamps then automatically 
switch from daytime running lights to low 
beams.
The headlamps may also come on when the 
sun is sitting low on a blue sky.
The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps
*.<
The automatic headlamp control cannot 
serve as a substitute for your personal 
judgment in determining when the lamps 
should be switched on in response to ambient 
lighting conditions. For example, the system 
cannot detect fog or hazy weather. To avoid 
safety risks, you should always switch on the 
low-beam headlamps manually under these 
conditions.<
Welcome lamps
If you leave the light switch in position 2 or 3 
when you park the car, the parking lamps and 
the interior lamps light up briefly when you 
unlock the vehicle.

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.
