All wheels are yellow
A flat tire or major drop in inflation pressure in
several tires.
Wheels, gray
The system cannot detect a flat tire due to a
malfunction.
Additional information
The status control display additionally shows
the current tire inflation pressures. It shows the
actual values read; they may vary depending
on driving style or weather conditions.
Carry out reset
Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
On the Control Display and on the vehicle:
1.
"Vehicle info"
2. "Vehicle status"
3. "Perform reset"
4. Start the engine - do not drive off.
5. Reset the tire inflation pressure using
"Perform reset".
6. Drive away.
The tires are shown in gray and the status is
displayed.
After driving faster than 19 mph/30 km/h for a
short period, the set tire inflation pressures are
accepted as reference values. The resetting
process is completed automatically while driv‐
ing. After successful completion of the reset,
the tires appear in green on the Control Display
and "Tire Pressure Monitor (TPM) active" is dis‐
played.
The progress of the reset is displayed.
You may interrupt this trip at any time. When
you continue the reset resumes automatically.
Low tire pressure message
The yellow warning lamp lights up. A
Check Control message is displayed.
▷ There is a flat tire or a major loss in
tire inflation pressure.
▷ A reset of the system was not carried out
after a wheel was changed. The system
therefore issues a warning based on the tire
pressures before the last reset.
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.
Run-flat tires, refer to page 193, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's sidewall.
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 risk
of an accident. Do not continue driving if the
vehicle is not equipped with run-flat tires. Fol‐
low the information on run-flat tires and con‐
tinued driving with these tires.◀
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 initialized. In this case, initialize
the system.
If identification of flat tire damage is not
possible, please contact a dealer’s service
