Collision Warning - BMW M5 Owner's Manual

Functional requirements
The system must have been initialized when the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured. In‐
itialize the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.,
whether or not the FTM is active.
1. "Vehicle Info"
2. "Vehicle status"
3. "Flat Tire Monitor"
The status is displayed.
Initialization
The initialization process adopts the set inflation
tire pressures as reference values for the detec‐
tion of a flat tire. Initialization is started by con‐
firming the inflation pressures.
Do not initialize the system when driving with
snow chains.
1. "Vehicle Info"
2. "Vehicle status"
3. "Reset"
4. Start the engine - do not drive away.
5. Start the initialization with "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.

Safety
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 174, 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 can‐
not be detected. Therefore, check the tire infla‐
tion 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.

Collision warning

The concept
If the vehicle does not include Active Cruise
Control with Stop & Go, the collision warning is
controlled via the camera in the base of the in‐
terior rearview mirror.
The system issues a two-phase warning of a
danger of collision at speeds above approx.
