Actions in the event of a flat tire
1. Identify the damaged tire.
To do this, check the tire inflation pressure in
all four tires, for instance using the tire pres‐
sure gage 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.
