As you drive, the Flat Tire Monitor 
keeps track of pressure levels in all four 
tires. The system alerts you whenever 
the inflation pressure of a tire falls sig-
nificantly below the pressure of another 
tire.

In the event of tire pressure loss, the 
rolling radius of the tire changes, and 
thereby the rotational speed of the 
wheel. This change is detected, and a 
flat tire warning is issued to the driver.

To ensure a reliable flat tire warning, 
the system must be initialized with the 
correct tire inflation pressures.

Initialize the system immediately 
after you have corrected a tire 

inflation pressure, or changed the tire 
or wheel.

<

The Flat Tire Monitor cannot pro-
vide you with advance warning of 

sudden and severe tire damage caused 
by external factors and does not detect 
the balanced and very gradual pressure 
loss that takes place in all four tires 
over an extended period of time.

<

The system could issue a false warning 
or function in a delayed manner in the 
following situations:
> System was not initialized 

> You are driving on a snow-covered or 

slippery road surface

> Performance-oriented driving: slip at 

the drive wheels, high levels of lateral 
acceleration

> You are driving with snow chains.

The initialization is completed 
while you are driving, and can be 

interrupted at any time. Initialization is 
automatically continued when you con-
tinue driving. When driving with snow 
chains, do not initialize the system.

<

1. Before driving off, start the engine 

but do not start driving

2. Press the button as long as you need 

to, but no more than 8 seconds, until 
the indicator lamp in the instrument 
cluster lights up in yellow for several 
seconds

3. Drive off. Initialization is completed 

during the drive without any feed-
back issued.

When driving with snow chains, 
do not initialize the system.
