Flat Tire Monitor FTM
The concept
The system does not measure the actual infla-
tion pressure in the tires.
The system detects a pressure loss in a tire by
comparing the rotational speeds of the indivi-
dual wheels while moving.
In the event of a pressure loss, the diameter and
therefore the rotational speed of the corre-
sponding wheel change. This is detected and
reported as a flat tire.
Functional requirement
The system must have be en initialized while the
tire inflation pressure was correct; otherwise,
reliable signaling of a fl at tire is not ensured.
Initialize the system afte r every correction of the
tire inflation pressure and after every tire or
wheel change.
System limitations
Sudden serious tire damage caused by
external influences cannot be indicated in
advance. <
A natural, even pressure loss in all four tires
cannot be detected. Therefore, check the tire
inflation pressure regularly.
In the following situatio ns, the system could be
delayed or malfunction:
> System has not been initialized.
> Driving on snowy or sl ippery road surface.
> Performance-oriented style of driving: slip in
the drive wheels, high lateral acceleration.
> Snow chains are attached.
When the vehicle is driven with a space-saver
spare tire, page 174, the Flat Tire Monitor
cannot function.
Initializing the system
The initialization process adopts the set inflation
tire pressures as refere nce values for the detec- tion of a flat tire. Initia
lization is started by con-
firming the inflation pressures.
Do not initialize the syst em when driving with
snow chains.
Using the button in the turn signal lever
1. Start the engine, but do not start driving.
2. Press the button in the turn signal indicator
as often as necessary until "SET/INFO" is
displayed.
3. Press and hold the button until the display
changes.
4. Press the button repeatedly until the corre-
sponding symbol and "RESET" are displayed.
5. Press and hold the button until the display
changes.
6. Start driving.
Initialization is completed while the car is on
the move, without any feedback.
The initialization is completed during
driving, which can be interrupted at any
time. When driving resumes, the initialization is
continued automatically. <

Indication of a flat tire
The warning lamps come on in yellow
and red. An acoustic signal also sounds.
There is a flat tire or a major loss in tire
inflation pressure.
1. Reduce speed and stop the vehicle with
caution. 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 152, are identi-
fied by a circular symbol containing the
letters RSC on the tire sidewall.
If the vehicle is not equipped with run-flat
tires, do not continue driving; continuing
to drive can result in serious accidents. <
When a flat tire is repo rted, 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 di splay of the Mobility
Kit, page 171, can be used for this purpose.
If the inflation pressure in all four tires is
correct, the Flat Tire Monitor might not have
been initialized. The system must then be
initialized.
If it is not possible to identify the damaged
tire, contact your MINI dealer.
2. Use the Mobility Kit to remedy the flat tire on
the damaged wheel, refer to page 170, or to
replace the damaged wheel, refer to
page 173.
Run-flat tires
You can continue driving with a damaged tire at
speeds up to 50 mph or 80 km/h.
Continued driving with a flat tire
When driving with a damaged tire: 1.
Avoid sudden braking and steering maneu-
vers.
2. Do not exceed a speed of 50 mph or
80 km/h.
3. At the next opportunity, check the air
pressure in all four tires.
If the inflation pressure in all four tires is
correct, the Flat Tire Monitor might not have
been initialized. The system must then be
initialized.
Possible driving distance with complete loss of
tire inflation pressure:
The distance it is possible to drive with a flat tire
depends on the load and the stress on the
vehicle while driving.
With an average load, it may be possible to drive
for approx. 50 miles/80 km.
When driving with damage d tires, the handling
characteristics change, e.g. the vehicle will skid
sooner when braking, braking distances will be
longer, or self-steering response will change.
Adapt your driving style accordingly. Avoid
turning abruptly and driv ing over obstacles such
as curbs, potholes, etc.
Since the possible driving distance depends to a
considerable degree on the strain exerted on
the vehicle while driving, it can be shorter or,
with a gentle dr iving style, can also be longer,
depending on the speed, road condition, exter-
nal temperature, vehicle load, etc.
Drive cautiously and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g.
reduced lane stability during braking, a longer
braking distance and altered self-steering
properties. <
Vibrations or loud noises while driving can
indicate final failure of the tire. Reduce
your speed and bring the vehicle to a stop;
otherwise, pieces of tire may come off, which
could result in an accident. Do not continue
driving and contact your MINI dealer.<

pressures in the tires are accepted as the
target values to be monitored. The system
reset is completed during your drive, and
can be interrupted at any time. When driving
resumes, the reset is continued automati-
cally. The indicator lamp goes out after the
system reset is completed.
Message for low tire inflation pressure
The warning lamps come on in yellow
and red. An acoustic signal also sounds.
1. Reduce speed and stop the vehicle
with caution. 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 152, are identi-
fied by a circular symbol containing the
letters RSC on the tire sidewall.
When a low inflation pressure is reported, the
Dynamic Stability Control DSC is activated.

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 Kit, refer to page 171, can be
used for this.
If the inflation pressure is correct in all four
tires, then the Tire Pressure Monitor may not
have been reset. The system must then be
reset.
If it is not possible to identify the damaged
tire, contact your MINI dealer.
2. Use the Mobility Kit to remedy the flat tire on
the damaged wheel, refer to page 170, or to
replace the damaged wheel, refer to
page. 173.
The use of tire sealant, e.g. Mobility Kit, can
damage the TPM wheel electronics. In this
case, have the electronics checked and
replaced if necessary at your earliest oppor-
tunity.
Run-flat tires
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
If the vehicle is not equipped with run-flat
tires, do not continue driving; continuing
to drive can result in serious accidents. <
