Safety information
Warning
A damaged regular tire with low or no tire
inflation pressure impacts handling such as
steering and braking response. There is a risk
of accident. Do not continue driving. Repair
the flat tire or replace the wheel.
Indication of a flat tire
The Flat Tire Monitor displays a message
when a tire is flat.
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
pressure loss.
Measure
1. Reduce your speed and come to a stop
carefully. Avoid sudden braking and steer-
ing maneuvers.
2. Follow the instructions for what to do in
case of a flat tire.
Actions in the event of a flat tire
1. In the event of a flat tire, identify the dam-
aged tire.
2. To do this, check the tire pressure in all four
tires, for instance using the tire pressure
display from a tire repair set.
When the tire inflation pressure in all four
tires is correct, the flat tire monitor may
not have been initialized. Then initialize the
system.

or by changing the wheel.
System limits
The Flat Tire Monitor may be react with a de-
lay 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 and serious tire damage caused
by external circumstances cannot be recog-
nized in advance.
▷ The system has not been initialized.
▷ When driving on a snow-covered or slippery
road.
▷ For sporty driving, e.g., due to slippage on
the drive wheels or high lateral accelera-
tion.
▷ When driving with snow chains.
Changing wheels/tires
General information
When a tire repair set is used, the wheel does
not always need to be changed immediately
in the event of a breakdown when there is tire
pressure loss.
If necessary, a suitable wheel change tool, e.g.,
a jack, is available as an accessory from an
authorized service center or another qualified
service center or repair shop.
