In the event of a pressure loss, the diameter and
therefore the rotational speed of the corre‐
sponding wheel change. This is detected and
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. Therefore, check the tire infla‐
tion pressure regularly.
The system could be delayed or malfunction in
the following situations:▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: slip in the drive wheels,
high lateral acceleration.▷When 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.
1."Vehicle Info"2."Vehicle status"3. "Flat Tire Monitor"
The status is displayed.
Initialization
The initialization process adopts the set inflation
tire pressures as reference values for the detec‐
tion of a flat tire. Initialization is started by con‐
firming the inflation pressures.
Do not initialize the system when driving with
snow chains.1."Vehicle Info"2."Vehicle status"3. "Reset"4.Start the engine - do not drive away.5.Start the initialization with "Reset".6.Drive away.
The initialization is completed while driving,
which can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Indication of a flat tire The yellow warning lamp lights up. A
Check Control message is displayed.
There is a flat tire or a major loss in tire
inflation pressure.
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 162, are labeled
with a circular symbol containing the letters
RSC marked on the tire sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.

Switching on
Press any button except:▷ALL program.▷Rear window defroster.▷Left side of Air volume button.▷Seat heating.
Microfilter/activated-charcoal filter
In external and recirculated air mode the micro‐
filter/activated charcoal filter filters dust, pollen,
and gaseous pollutants out of the air.
This filter should be replaced during scheduled
maintenance, refer to page 168, of your vehicle.
Ventilation
Front ventilation
▷Lever for changing the air flow direction, ar‐
row 1.▷Thumbwheels for opening and closing the
vents continuously, arrows 2.▷Thumbwheel to vary the temperature, ar‐
row 3.
Toward blue: colder.
Toward red: warmer.
Adjusting the ventilation
▷Ventilation for cooling:
Adjust the vent to direct the air in your di‐
rection, such as if the vehicle interior is hot
from the sun.▷Draft-free ventilation:
Adjust the vent to let the air flow past you.
Ventilation in the rear
▷Thumbwheel for continuous opening and
closing of the vents, arrow 1.▷Thumbwheel to vary the temperature, ar‐
row 2.
Toward blue: colder.
Toward red: warmer.▷Lever for changing the air flow direction, ar‐
row 3.
Parked-car ventilation
The concept
The parked-car ventilation ventilates the vehicle
interior and lowers its temperature, if necessary.
The system can be switched on and off at any
external temperature, either directly or by using
two preset switch-on times. It remains switched
on for 30 minutes.
Open the vents to allow air to flow out.
Operation can be performed via iDrive.
