Alarm system
The concept
The vehicle alarm system responds to:
▷Opening of a door, the hood or the trunk lid.▷Movements in the vehicle: interior motion
sensor, refer to page 31.▷When the car's inclination changes, for in‐
stance if an attempt is made to jack it up and
steal the wheels or to raise it prior to towing
away.▷Interruptions in battery voltage.
The alarm system signals unauthorized entry
attempts for a short time by means of:
▷By sounding an acoustic alarm.▷By switching on the hazard warning system.▷By flashing the high beams.Arming and disarming the alarm
system
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.
Trunk lid and armed alarm system
The trunk lid can be opened using the remote
control, even if the alarm system is armed.
Press the button on the remote control for
approx. one second.
Note the opening height of the trunk lid
During opening, the trunk lid pivots back
and up. Ensure that there is sufficient clearance
when the trunk lid opens; otherwise, damage
may result.◀
After the lid is closed, it is locked and monitored
again by the alarm system.

The transmission provides assistance in the fol‐
lowing situations:
▷Upshifts and downshifts are executed only
when they will result in a plausible combina‐
tion of engine and vehicle speed; thus, for
example, a downshift that would cause the
engine to overrev will not be executed by the
system.▷When the vehicle stops, the transmission
automatically shifts down to first gear.▷Shortly before the vehicle slows down to be‐
low the minimum speed of the gear currently
engaged, the transmission automatically
shifts down without requiring your interven‐
tion.Shifting down rapidly: even in manual mode, you
can skip several gears to achieve optimal accel‐
eration. Do so by pressing the accelerator past
the resistance point.

The indicator lamp for the front passenger air‐
bags indicates the operating status of the front
and side airbags on the front passenger side de‐
pending on the seat occupation. The indicator
lamp shows whether the passenger airbags are
activated or deactivated.▷The indicator lamp lights up when a child
who is properly seated in a child restraint
system intended for that purpose is de‐
tected on the seat or the seat is empty. The
front and side airbags on the front passen‐
ger side are not activated. Most child seats
are detected by the system, Especially the
child seats required by NHTSA at the time
that the vehicle was manufactured. After in‐
stalling a child seat, make sure that the indi‐
cator lamp for the front passenger airbags
lights up. This indicates that the child seat
has been detected and the front passenger
airbags are not activated.▷The indicator lamp does not light up when,
for example, a person of sufficient size and
in a correct sitting position is detected on
the seat. The front and front passenger air‐
bags on the front passenger side are acti‐
vated.
Operational readiness of airbag system
When the ignition, refer to page 46, is switched
on, the warning lamp comes on briefly to indi‐
cate that the entire airbag system and the belt
tensioners are operational.
Airbag system malfunction▷The warning lamp does not light up when the
ignition is switched on.▷Warning lamp remains permanently on.
Have the airbag system checked without
delay if there is a malfunction
In the event of a malfunction in the airbag sys‐
tem, have it checked without delay; otherwise,
there is the risk that the system will not function
as intended even if a sufficiently severe accident
occurs.◀
Flat Tire Monitor FTM
The concept
The system detects a pressure loss in a tire on
the basis of speed differences between the in‐
dividual wheels during a trip.
In the event of pressure loss, the rolling circum‐
ference changes and, thus, the rotating speed
of the affected wheel. This change is detected
and is reported as a flat tire.
Functional requirements
The system must have been initialized when the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured. In‐
itialize the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires can‐
not be detected.
The system could be delayed or malfunction in
the following situations:
▷When the system has not been initialized.Seite 75SafetyControls75
Online Edition for Part no. 01 40 2 609 184 - 09 11 500
in spite of the fact that the tire is filled to the cor‐
rect inflation pressure.
The system is deactivated and is unable to de‐
tect flat tires if a wheel not equipped with TPM
electronics has been mounted, e.g., a compact
wheel, or if TPM is experiencing temporary in‐
terference from other systems or devices that
use the same frequency.
Resetting the system
Reset the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
Operating principle, refer to page 62.1.Start the engine, but do not start driving.2.Lightly push button 1 in the turn indicator
lever up or down repeatedly until the appro‐
priate symbol appears in the display, ac‐
companied by the word "RESET".3.Press button 2 to confirm your choice of the
Tire Pressure Monitor.
The following display appears:4.Press button 2 for approx. 5 seconds until
the small warning lamp lights up yellow and
the following display appears:5.Drive away.
After driving a few minutes, the set inflation
pressures in the tires are accepted as the
target values to be monitored. The system
reset is completed during your drive, and
can be interrupted at any time. When driving
resumes, the reset is continued automati‐
cally. The indicator lamp goes out after the
system reset is completed.
Low tire pressure message
The warning lamps come on in yellow
and red. In addition, a signal sounds.
▷There is a flat tire or a major loss in
tire inflation pressure.▷The system was not reset after a wheel
change and thus issues warnings based on
the inflation pressures initialized last.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with reg‐
ular tires or run-flat tires.
Run-flat tires , refer to page 160, are labeled
with a circular symbol containing the letters
RSC marked on the tire sidewall.Seite 78ControlsSafety78
