Alarm system
The concept
When the vehicle is locked, the vehicle alarm
system responds to:▷Opening a door, the hood or the tailgate.▷Movements in the vehicle interior▷Changes in the vehicle tilt, e. g., during at‐
tempts at stealing a wheel or when towing
the car.▷Disconnected battery voltage.
The alarm system briefly signals tampering:
▷Acoustic alarm.▷By switching on the hazard warning system.▷By flashing the daytime running lights.
Arming and disarming the alarm system
When you lock or unlock the vehicle, either
with the remote control or via the Comfort Ac‐
cess, the alarm system is armed or disarmed at
the same time.

▷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,
e.g., a correctly seated person of sufficient
size is detected on the seat. The airbags on
the front passenger side are activated.
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.
With a respective message appearing on Con‐
trol Display calibrate the front seats to keep the
accuracy of this function over the long-term.
Calibrating the front seats
A corresponding message appears on the Con‐
trol Display.
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 message on the Control Display 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.
Unobstructed area of movement
Ensure that the area of movement of the
seats is unobstructed to avoid personal injury
or damage to objects. ◀
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.
Hints Tire damage due to external factors
Sudden tire damage caused by external
circumstances cannot be recognized in ad‐
vance. ◀
With use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 172.
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.Seite 96CONTROLSSafety96
