System limitations
Each time the engine is started, the program set
for the remote control in use is active, refer to M
Key settings on page 45.
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period of
time.<
You can also set and call up your preferred
program via MDrive, refer to page 44.
In the following situations, the system could be
delayed or malfunction:
Drive-off assistant
>
System has not been initialized
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary >
Driving on snowy or slippery road surface
to use the parking brake for this.
>
Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration
1.
2.
Hold the car in place by depressing the
brake.
>
Snow chains are attached
Release the brake and drive off without
delay.
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Drive off without delay after
releasing the brake. Otherwise, the drive-off
assistant will no longer hold the car in place
after approx. 2 seconds and the car will start to
roll backwards.<
Using the button in the center console
1.
2.
Start the engine, but do not start driving.
Flat Tire Monitor FTM*
Press the button for approx. 4 seconds until
the warning lamp in the instrument cluster
lights up yellow. Warning lamp, refer to Indi-
cation of a flat tire on page 79.
The concept
The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
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 requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
3.
Start to drive.
Initialization is completed while the car is
moving, without any feedback.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
Via iDrive
iDrive, for operating principle refer to page 16.
