The status is displayed.
Initialization required
An initialization must be performed in the fol-
lowing situations:
▷ After the tire inflation pressure has been
adjusted.
▷ After a tire or wheel change.
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.
Via iDrive:
1.
"My Vehicle"
2. "Vehicle status"
3. "Flat Tire Monitor"
4. Start the engine but do not drive off.
5. Start the initialization with: "Perform reset"
6. Drive away.
The initialization is completed while driving,
which can be interrupted at any time.
The initialization automatically continues when
driving continues.
Messages
General information
When a flat tire is indicated, the DSC Dynamic
Stability Control is turned on, if needed.
Safety information
Warning
A damaged regular tire with low or missing
tire inflation pressure impacts handling, such
as steering and braking response. Runflat
tires can maintain limited stability. There is a
risk of accident. Do not continue driving if the
vehicle is equipped with normal tires. Follow
the information on runflat tires and continued
driving with these tires.
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
pressure loss.
Measure
1.
Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu-
vers.
2. Check whether the vehicle is fitted with
standard tires or runflat tires.
Runflat tires, refer to page 244, are labeled
with a circular icon containing the letters
RSC marked on the tire sidewall.
Actions in the event of a flat tire
Standard tires
1.
Identify the damaged tire.
To do this, check the air pressure in all four
tires, for instance using the tire pressure
display of a flat tire kit.
