PDC Park Distance Control
*
The concept PDC provides extra safety and conve-
nience during parking maneuvers. Sig-
nal tones indicate the current distance
to an object behind or in front of your
vehicle. To do this, four ultrasonic sen-
sors in the front and rear bumpers each
measure the distance to the nearest
object. The detection range of the front
sensors and the two sensors located at
the ends of the rear bumper is approx.
2 ft/60 cm, while the rear center sen-
sors can detect objects to a distance
of approx. 5 ft/1.50 m.
PDC is a parking aid that can
indicate objects when they are
approached slowly, as is usually the
case when parking. Avoid approaching
objects too fast, otherwise the system
may give warning of physical obstacles
too late.<
Automatic operationThe system starts to operate automati-
cally approx. one second after you
select reverse or move the selector
lever into the R position with the ignition
key in position 2. Wait this short period
before backing up. The system
switches off when you shift back out
of reverse.
Manual activation Press the button, the indicator lamp
lights up. Manual deactivation Press the button again; the indicator
lamp goes out.Automatic deactivationAfter driving a distance of more than
approx. 160 ft/50 m or exceeding a
speed of approx. 20 mph/30 km/h, the
system switches off and the indicator
lamp goes out. You may switch the sys-
tem on again manually as needed. 530de418

Parking lamps/side marker lamps
The front, rear and side vehicle
lighting is switched on. You can
use the parking lamps for park-
ing. For lighting on one side for parking
as an additional feature, refer to
page104.
Low beams
When the ignition is switched off
and the low beams are on, only
the parking lamps/side marker
lamps remain on.
530us215
Pathway lighting:
When you activate the headlamp
flasher after parking the vehicle and
switching off the lamps, the low beams
will come on for a brief period. You may
also have this function deactivated if
you wish.<
Lights on warning Whenever you open the driver's door,
after having turned the ignition key to
position 0, you will hear an acoustic sig-
nal for a few seconds to remind you that
the lamps have not been switched off.
On vehicles with alphanumeric Check
Control
*:
The reminder is given through the
Check Control.
Daytime driving lamps
*
The headlamps are automatically
switched on for daytime driving at igni-
tion key position 2.
Automatic headlamp control
*
When you set the switch to this
position, the system activates
and switches on and off the low
beams in response to changes in ambi-
ent light conditions, for instance, in tun-
nels, at dawn and dusk, and in rain and
snow.
The low beams remain switched
on regardless of the ambient light
when you switch on the front fog
lamps.<
Automatic headlamp control can-
not serve as a substitute for the
driver's judgment in determining when
the vehicle lamps should be switched
on. For example, the system cannot
detect fog. To avoid safety risks, you
should always switch on the lamps
manually under these conditions.<
You can have the sensitivity of the
headlamp control system adjusted
on your vehicle.<

Adaptive Head Light
*
High beams/roadside parking lamps
The concept Adaptive Head Light is a variable head-
lamp control system that enables better
illumination of the road surface.
Depending on the steering angle and
other assumptions, the light from the
headlamp follows the course of the
road.Activating Adaptive Head Light
In ignition key position 2, turn
the light switch to the position
'Automatic headlamp control',
refer to page103.
To avoid blinding oncoming traffic, the
Adaptive Head Light
>is not active when driving in reverse
>is active only when pointing toward
the passenger side.
MalfunctionThe LED next to the symbol for auto-
matic headlamp control flashes. Adap-
tive Head Light is faulty or has failed.
Have the system checked as soon as
possible.

As an additional feature, you can illu-
minate your vehicle on either side for
parking, if you wish to do so:
With the ignition key in position 0,
engage the lever in the appropriate turn
signal position.
The roadside parking lamps
drain the battery. Avoid use for
extended periods of time, otherwise, it
will no longer be possible to start the
engine.<530de265
