completed automatically as you drive. On the
Control Display, the tires are shown in green
and "Status: TPM active" is displayed again.
The trip can be interrupted at any time. If you
drive away again, the process resumes auto‐
matically.
If a flat tire is detected while the system is re‐
setting, all tires on the Control Display are dis‐
played in yellow. The message "Low tire!" is
shown.
Low tire pressure message
The warning lamps come on in yellow
and red. A message is displayed on the
onboard monitor. In addition, a signal
sounds.
▷ There is a flat tire or substantial loss of infla‐
tion pressure on the indicated wheel.
▷ The system was not reset after a wheel
change and thus issues warnings based on
the inflation pressures initialized last.
1. Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.
2. Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 232, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a low inflation pressure is indicated, DSC
Dynamic Stability Control is switched on if nec‐
essary.
Actions in the event of a flat tire
Normal tires
1.
Identify the damaged tire.
Do this by checking the air pressure in all
four tires. The tire pressure gauge of the
Mobility System, refer to page 233, can be
used for this purpose.
If the tire inflation pressure in all four tires is
correct, the Tire Pressure Monitor may not
have been reset. Reset the system.
If an identification is not possible, please
contact the service center.
2. Rectify the flat tire using the Mobility Sys‐
tem, refer to page 233, or replace the
damaged wheel, refer to page 249.
Use of tire sealant, e.g., the Mobility Sys‐
tem, may damage the TPM wheel electron‐
ics. In this case, have the electronics
checked at the next opportunity and have
them replaced if necessary.
Run-flat tires
You can continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
Continued driving with a flat tire
If continuing to drive with a damaged tire:
1.
Avoid sudden braking and steering maneu‐
vers.
2. Do not exceed a speed of 50 mph/80 km/h.
3. Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four tires is
correct, the Tire Pressure Monitor may not
have been reset. Reset the system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
