In these cases:
1. Reduce your speed and drive moderately.
Do not exceed a speed of
80 mph/130 km/h.
2. At the next opportunity, e.g., gas station,
check and correct the tire inflation pres‐
sure in all four tires, if necessary.
3. Reset the system.
Message in case of sharp tire inflation
pressure loss
The yellow warning lamp lights up.
In addition, a symbol with the affected
tires will be displayed in the Check
Control message.
There is a flat tire or a major loss in tire in‐
flation pressure.
No reset was performed for the system.
System will issue a warning related to the
tire inflation pressures stored during the
last reset.
In these cases:
1.
Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.
2. Check whether the vehicle is fitted with
normal tires or run-flat tires.
WARNING
A damaged regular tire with low or miss‐
ing tire inflation pressure impacts handling,
such as steering and braking response. Run-
flat tires can maintain limited stability. There is
a risk of an accident. Do not continue driving if
the vehicle is not equipped with run-flat tires.
Follow the information on run-flat tires and
continued driving with these tires.◀
Run-flat tires, refer to page 272, are labeled
with a circular symbol containing the letters
RSC marked on the tire's sidewall.
A low tire inflation pressure might turn on DSC
Dynamic Stability Control.
Actions in the event of a flat tire
Normal tires
1. Identify the damaged tire.
Check the air pressure in all four tires, e.g.,
using the tire pressure gage of a tire repair
kit.
If the tire inflation pressure in all four tires
is correct, the Tire Pressure Monitor may
not have been reset. In this case, perform
the reset.
If identification of flat tire damage is not
possible, please contact a dealer’s service
center or another qualified service center
or repair shop.
2.
Repair the flat tire, e.g., with a tire repair kit
or by changing the tire.
Use of sealant, e.g., the Mobility System, may
damage the TPM wheel electronics. In this
case, have the electronics checked at the next
opportunity and have them replaced, if
needed.
Run-flat tires
Safety information
WARNING
Your vehicle handles differently when a
run-flat tire is damaged and has low or missing
tire inflation pressure, e.g., your lane stability is
reduced when braking, braking distances are
longer and the self-steering properties will
change. There is a risk of an accident.
Drive moderately and do not exceed a speed of
50 mph/80 km/h.◀
Maximum speed
You may continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
