Initialization required
An initialization must be performed in the follow‐
ing situations:
▷ After the tire inflation pressure has been ad‐
justed.
▷ After a tire or wheel replacement.
Performing initialization
When initializing, the set tire inflation pressures
serve as reference values in order to detect a flat
tire. Initialization is started by confirming the tire
inflation pressures.
Do not initialize the system when driving with tire
chains.

Indication of a flat tire
A yellow warning light is illuminated in
the instrument cluster.
In addition, an icon with a Check Control mes‐
sage appears on the Control Display.
Icon Possible cause
There is a flat tire or a major tire pres‐
sure loss.
Measure
1. Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.
Actions in the event of a flat tire
1. Identify the damaged tire.
To do this, check the tire pressure in all four
tires, for instance using the tire pressure dis‐
play of a flat tire kit.
If the tire inflation pressure in all four tires is
correct, the Flat Tire Monitor may not have
been initialized. In this case, initialize the sys‐
tem.
If identification of flat tire damage is not pos‐
sible, please contact a dealer's service center
or another qualified service center or repair
shop.
2. Repair the flat tire, e.g., with a flat tire kit or by
changing the wheel.
System limits
The system could be delayed or malfunction in
the following situations:
▷ A natural, even tire pressure loss in all four
tires will not be recognized. Therefore, check
the tire inflation pressure regularly.
▷ Sudden serious tire damage caused by exter‐
nal circumstances cannot be recognized in
advance.
▷ The system has not been initialized.
