Safety information
Warning
A damaged regular tire with low or no 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 driv-
ing if the vehicle is equipped with normal
tires. Follow the information on runflat
tires and continued driving with these
tires.
If a tire inflation pressure check is
required
Message
When using tires with special approval, the
Tire Pressure Monitor displays a message
if it is necessary for you to check the tire
pressure.
An icon with a Check Control message ap-
pears on the Interaction Unit.
Icon Possible cause
Inflation was not carried out
according to specifications,
e.g., the tire has not been suffi-
ciently inflated.
The system has detected a
wheel change, but no reset was
done.
The tire inflation pressure has
fallen below the level of the last
reset.
No reset was performed for the
system. The system issues a
warning based on the tire in-
flation pressures stored during
the last reset.
Measure
1. Check the tire pressure and correct as
needed.
2. Perform a system reset.
If the tire inflation pressure is too low
Message

A yellow warning light illuminates
on the Interaction Unit.
In addition, an icon with a Check Control
message appears on the Interaction Unit.

pressures stored during the last
reset.
Measure
1. Reduce the vehicle speed. Do not
continue to exceed a speed of
80 mph/130 km/h.
2. At the next opportunity, for instance at
a filling station, check the tire inflation
pressure in all four tires and correct if
necessary.
3. Perform a system reset.
If there is a significant tire pressure
loss
