A yellow warning light illuminates
on the Interaction Unit.
In addition, an icon with a Check Control
message appears on the Interaction Unit.
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
steering maneuvers.
2. Check whether the vehicle is fitted with
standard tires or runflat tires.
Runflat tires are labeled with a circular
icon containing the letters RSC marked
on the tire sidewall.
3. Follow the instructions for what to do in
case of a flat tire.
Actions in the event of a flat tire
Standard tires
1. In the event of a flat tire, identify the
damaged tire.
2. To do this, check the tire pressure in
all four tires, for instance using the tire
pressure display of a flat tire kit.
When the tire inflation pressure in all
four tires is correct, the flat tire monitor
may not have been initialized. Then ini-
tialize the system.
If tire damage cannot be identified, con-
tact an authorized service center or an-
other qualified service center or repair
shop.
3. Repair the flat tire, e.g., using a tire re-
pair set or by changing the wheel.
Runflat tires
Safety information
Warning
The vehicle handles differently when a
runflat tire has insufficient or no tire pres-
sure; for instance, reduced directional sta-
bility when braking, braking distances are
longer and the self-steering properties will
change. There is a risk of accident, injury,
or property damage. Drive moderately and
do not exceed a speed of 50 mph/80 km/h.
Warning
Vibrations or loud noises while driving
can indicate the final failure of a tire. Tire
components may come loose. There is a
risk of accident, injury, or property dam-
age. Reduce your speed and stop. Do not
continue driving. Contact an authorized
service center or another qualified service
center or repair shop.
Maximum speed
You may continue driving with a damaged
tire at speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
Follow the following when continuing to
drive with a damaged tire:
1. Avoid sudden braking and steering ma-
neuvers.
2. Do not exceed a speed of
50 mph/80 km/h.
3. Check the tire inflation pressure in all
four tires at the next opportunity.
When the tire inflation pressure in all
four tires is correct, the flat tire monitor
may not have been initialized. In this
case, initialize the system.
