Technology for driving comfort and safety CONTROLS
75
All wheels yellow
> There is a flat tire or substantial loss of tire
pressure in several tires.
> The system was not reset after a wheel
change and thus issues a warning based on
the inflation pressures initialized last.
Gray wheels
The system cannot detect a puncture.
Reasons for this may be:
> TPM is being reset.
> Interference from systems or devices with
the same transmission frequency.
> Malfunction.
Resetting the system
Reset the system again after each correction of
the tire inflation pressure and after every tire or
wheel change.
1. "Vehicle Info"
2. "Vehicle status"
3. "Reset"
4. Start the engine – do not drive away.
5. Select "Reset" to start the initialization.
6. Start to drive.
The tires are shown in gray and "Resetting
TPM..." is displayed.
After driving a few minutes, the set inflation
pressures in the tires are accepted as the target
values to be monitored. The resetting process is
completed automatically as you drive. The tires
are depicted in green on the Control Display and
"Status: TPM active" is displayed again.
The trip can be interrupted at any time. When
driving resumes, resetting is continued auto-
matically.
If a flat tire is detected while the system is
resetting, all tires on the Control Display
are displayed in yellow. The message "Low tire!"
is displayed.<
Message for low tire inflation pressure
The warning lamps come on in yellow
and red. A message appears on the on-
board computer. An acoustic signal also
sounds. The position of the faulty tire is
displayed.
> There is a flat tire or substantial loss of tire
pressure.
> The system was not reset after a wheel
change and thus issues a warning based on
the inflation pressures initialized last.
1. Reduce speed and stop the vehicle with cau-
tion. Avoid sudden braking and steering
maneuvers.
2. Check whether the vehicle is equipped with
normal tires or with run-flat tires
*.
Run-flat tires, refer to page 196, are identi-
fied by a circular symbol containing the let-
ters RSC on the tire sidewall.
When a low inflation pressure is reported, the
Dynamic Stability Control DSC is activated.
Actions in the event of a flat tire
Normal tires
1. Identify the damaged tire.
To do so, check the inflation pressure in all
four tires. The inflation pressure display of
the Mobility System, refer to page 213, can
be used for this.
