The lamp indicates whether the airbags are ei‐
ther activated or deactivated.
▷The indicator lamp lights up
when a child is properly
seated in a child restraint fix‐
ing system or when the seat
is empty. The airbags on the
front passenger side are not
activated.
▷The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient size is detected on the seat. The
airbags on the front passenger side are ac‐
tivated.
Detected child seats
The system generally detects children seated in
a child seat, particularly in child seats required
by NHTSA when the vehicle was manufactured.
After installing a child seat, make sure that the
indicator lamp for the front-seat passenger air‐
bags lights up. This indicates that the child seat
has been detected and the front-seat passen‐
ger airbags are not activated.
Strength of the driver's and front-seat
passenger airbag
The explosive power that activates driver's/
front passenger's airbags very much depends
on the positions of the driver's/front passeng‐
er's seat.
To maintain the accuracy of this function over
the long-term, calibrate the front seats as soon
as a relevant Check Control message is dis‐
played. A message also appears on the Control
Display.
Calibrating the front seats
WARNING
There is risk of jamming when moving the
seats. There is risk of injuries or risk of property
damage. Make sure that the area of movement
of the seat is clear prior to any adjustment.◀
An appropriate Check Control message is dis‐
played.
1.Move the respective seat all the way for‐
ward.
2.Move the respective seat forward again. It
moves forward briefly.
3.Readjust the seat to the desired position.
The calibration procedure is completed when
the Check Control message disappears.
If the message continues to be displayed, re‐
peat the calibration.
If the message does not disappear after a re‐
peat calibration, have the system checked as
soon as possible.
Tire Pressure Monitor
TPM
The concept
The system monitors tire inflation pressure in
the four mounted tires. The system warns you if
there is a significant loss of pressure in one or
more tires. For this purpose, sensors in the tire
valves measure the tire inflation pressure.
Information
With use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 182.
Functional requirements
The system must have been reset with the cor‐
rect tire inflation pressure; otherwise, reliable
signaling of tire pressure loss is not assured.
Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
Always use wheels with TPM electronics to en‐
sure that the system will operate properly.

PDC Park Distance Con‐
trol
The concept
PDC is a support when parking. When you
slowly approach an object in the rear - or also
in the front of the vehicle if the feature is avail‐
able - then the object is reported through:
▷Signal tones.▷Visual display.
General information
Ultrasound sensors in the bumpers measure
the distances from objects.
The maneuvering range, depending on obsta‐
cles and environmental conditions, is approx.
6 ft/2 m.
An acoustic warning is first given with the fol‐
lowing circumstances:
▷By the front middle sensors and the two
corner sensors at approx. 24 inches/60 cm.
▷By the rear middle sensors at approx.
5 ft/1.50 m.
▷When a collision is imminent
Information
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal
tone.
WARNING
The system does not relieve from the per‐
sonal responsibility to correctly assess the traf‐
fic situation. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic and vehicle surroundings closely and ac‐
tively interfere in the respective situations.◀
WARNING
Due to high speeds when PDC is acti‐
vated, the warning can be delayed due to phys‐
ical circumstances. There is risk of injuries or
risk of property damage. Avoid approaching an
object too fast. Avoid driving off fast while PDC
is not yet active.◀

Signal tones
When approaching an object, an intermittent
sound indicates the position of the object. E. g.
if an object is detected to the left rear of the ve‐
hicle, a signal tone sounds from the left rear
speaker.
The shorter the distance to the object, the
shorter the intervals.
If the distance to a detected object is less than
approx. 10 inches/25 cm, a continuous tone is
sounded.
With front PDC: if objects are located both in
front of and behind the vehicle, an alternating
continuous signal is sounded.
The signal tone is switched off, when selector
lever position P is engaged on vehicles with
Steptronic transmission.
