tire inflation pressure and after every tire or
wheel change.1."Vehicle Info"2."Vehicle status"3. "Perform reset"4.Start the engine - do not drive away.5.Carry out the reset with "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 tire inflation pressures set are
accepted as reference values. The reset is
completed automatically during driving.
After a successfully completed Reset, the
wheels on the Control Display are shown in
green and "Tire Pressure Monitor (TPM)
active" is displayed.
The trip can be interrupted at any time. If you
drive away again, the reset resumes automati‐
cally.
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.▷No reset was performed for the system.
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.Identify the damaged wheel. Do so by
checking the tire inflation pressure using
the Mobility System. Correcting the tire in‐
flation pressure, refer to page 175.3.Repair flat tire with the Mobility System, re‐
fer to page 172, or replace the damaged
wheel.
Required inflation pressure check
message
A Check Control message is displayed.
Check the tire inflation pressure and carry out
a reset of the system.
In some cases, a wheel was changed without
having carried out a reset.
System limits
The system does not function properly if a re‐
set has not been carried out, e.g., a flat tire is
reported even though the tire inflation pres‐
sures are correct.
The tire pressure depends on the temperature
of the tire. If the tire temperature rises, e.g.,
due to driving or because of the heat of the
Sun, the tire inflation pressure increases also.
The tire pressure is reduced when the tire
temperature falls again. This behavior may
cause a warning to be issued if temperatures
fall very sharply.
Malfunction The yellow warning lamp flashes and
then lights up continuously. A Check
Control message is displayed. No flat
tire or loss of tire pressure can be detected.
Display in the following situations:
▷A wheel without TPM electronics is fitted:
have the service center check it if neces‐
sary.▷Malfunction: have the system checked by
your service center.▷TPM was unable to complete the reset.
Reset the system again.▷Disturbance by systems or devices with
the same radio frequency: after leaving the
area of the disturbance, the system auto‐
matically becomes active again.Seite 103SafetyControls103

Do not initialize the system when driving with
snow chains.1."Vehicle Info"2."Vehicle status"3. "Perform reset"4.Start the engine - do not drive away.5.Start the initialization with "Perform reset".6.Drive away.
The initialization is completed while driving,
which can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Indication of a flat tire 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.
1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Identify the damaged wheel. Do so by
checking the tire inflation pressure using
the Mobility System. If the tire inflation
pressure in all tires is correct, the Flat Tire
Monitor may not have been initialized. In
this case, initialize the system.3.Repair flat tire with the Mobility System, re‐
fer to page 172, or replace the damaged
wheel.
System limits
Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires
cannot be detected. Therefore, check the tire
inflation pressure regularly.
The system could be delayed or malfunction in
the following situations:▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: slip in the drive
wheels, high lateral acceleration.▷When driving with snow chains.
Intelligent Safety
The concept
Depending on how the vehicle is equipped, In‐
telligent Safety consists of one or more of the
following systems, which can help to avoid an
imminent collision. These systems are active
automatically every time the engine is started
using the Start/Stop button:
▷Collision warning with City Braking func‐
tion, refer to page 106.▷Pedestrian warning, refer to page 108.
Note
Personal responsibility
The system does not serve as a substi‐
tute for the driver's personal judgment of the
traffic situation.
Be aware of the traffic situation and the vehi‐
cle's surroundings at all times, otherwise an
accident is still possible despite all warnings.◀

▷Thumbwheels for opening and closing the
vents continuously, arrows 3.
Adjusting the ventilation
▷Ventilation for cooling:
Adjust the vent to direct the air in your di‐
rection, e.g., if the vehicle interior is hot
from the sun.▷Draft-free ventilation:
Adjust the vent to let the air flow past you.
Parked-car ventilation
The concept The parked-car ventilation ventilates the vehi‐
cle interior and lowers its temperature, if nec‐
essary.
The switch-on time is automatically deter‐
mined based on the temperature. The system
promptly switches on before the selected de‐
parture time.
The system can be switched on and off di‐
rectly or by using two preset switch-on times.
It remains switched on for 30 minutes.
The system can be switched on and off di‐
rectly or by using two preset departure times.
Operation can be performed via iDrive.
