Flat Tire Monitor FTM*
The concept
The system does not measure the actual infla-
tion pressure in the tires.
The system detects a tire pressure loss due to
speed comparisons among the individual
wheels as you drive.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. The system detects this
and reports it as a flat tire.
Functional requirement
The system has to have been initialized at the
correct inflation pressure; otherwise, a reliable
reporting of a flat tire is not assured.
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reinitialize the system.
System limitations
It is impossible to provide advance warn-
ing of sudden, severe tire damage caused
by outside influences.<
The system will not detect a natural, uniform
pressure loss in all four tires. Therefore you
should check the inflation pressure regularly.
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration
>Driving with snow chains
*
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
In the initialization, the set inflation pressures
are adopted as reference values for the detec-
tion of a flat tire. The initialization is begun by
confirmation of the inflation pressures.
Do not initialize the system while snow chains
are attached.
1."Vehicle Info"
2."Vehicle status"
3."Reset"
4.Start the engine – do not drive away.
5.Start the initialization using "Reset".
6.Start driving.
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.<

Indication of a flat tire
The warning lamps come on in yellow
and red. A message appears on the
Control Display. In addition, an
acoustic signal sounds. There is a flat
tire or substantial loss of tire pressure.
What to do in case of a flat tire
Run-flat tires
With a damaged tire, is possible to continue
driving at speeds of up to 50 mph/80 km/h.
Do not continue driving if the vehicle is
not equipped with run-flat tires, refer to
page223; continued driving could result in a
severe accident.<
When 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.At the next opportunity, check the air pres-
sure in all four tires.
If all four tires are inflated to the cor-
rect pressures, the Flat Tire Monitor
might not have been initialized. The system
must then be initialized.<
Possible travel distance with complete tire
pressure loss:
>With a light load:
1 to 2 persons without luggage:
Approx. 155 miles/250 km
>With a medium load:
2 persons, cargo area full, or 4 persons
without luggage:
Approx. 94 miles/150 km
>With a full load:
4 or more persons, cargo area full:
Approx. 30 miles/50 km
Drive cautiously and do not exceed a
speed of 50 mph/80 km/h.
When there is a tire pressure loss, the handling
characteristics change, e.g. there will be
reduced directional stability during braking,
braking distances will be longer, and self-steer-
ing response will change.<Vibrations or loud noises during driving
may indicate the final failure of the tire.
Reduce your speed and bring the vehicle to a
stop; otherwise, tire components may become
detached, which could result in an accident.
Do not continue driving; instead, contact your
BMW center.<
Tire Pressure Monitor TPM*
The concept
Check the inflation pressure in the four installed
tires. The system notifies you if there is a signif-
icant loss of pressure in one or more tires.
Functional requirement
The system has to have been reset at the cor-
rect inflation pressure; otherwise, a reliable
reporting of a flat tire is not assured.
Always use wheels with TPM electronics to
assure a trouble-free function of the system.
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
System limitations
It is impossible to provide advance warn-
ing of sudden, severe tire damage caused
by outside influences.<
The system does not function correctly if it has
not been reset. For example, a flat tire may be
indicated even though the tire inflation pres-
sures are correct.
The system is inactive and cannot indicate a flat
tire:
>when a wheel without TPM electronics is
installed.
>when other systems or devices that use the
same radio frequency interfere with TPM.

Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When the vehicle is parked
Condensation forms while the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. In some situations,
this can result in sudden loss of tire pressure.<
Make sure that no liquids are spilled or
leak from their containers in the cargo
area, as this could result in damage to the vehi-
cle.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise, overloading
can result in damage to the vehicle and
unstable driving conditions.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX kilograms or YYY
pounds.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
1,400 lbs. and there will be five 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
650 lbs:
1,400 lbs. minus 750 lbs. = 650 lbs.
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.

Care
234
Steam jets/high-pressure washers
When using steam jets or high-pressure
washers, ensure that you maintain suffi-
cient clearance to the vehicle and do not exceed
a temperature of 1407/606.
Insufficient clearance or excessive pressure or
temperature can lead to component damage or
water penetration. Follow the operating instruc-
tions of the high-pressure washer.<
When using high-pressure washers, do
not spray against the sensors and cam-
eras, e.g. of the Park Distance Control or Rear
View Camera, for an extended period and main-
tain a distance of at least 1 ft/30 cm.<
Manual car wash
When washing the vehicle by hand, use large
quantities of water and car shampoo if neces-
sary. Clean the vehicle with a sponge or wash-
ing brush, applying light pressure only.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion to prevent unintentional activation of the
wipers.<
Observe local regulations pertaining to
washing vehicles by hand.<
Headlamps
Do not rub them dry and do not use abrasive or
corrosive cleaning agents.
Loosen dirt, e.g. insects, with shampoo or
insect remover and wash away with copious
quantities of water.
Thaw ice with a windshield deicer and do not
use an ice scraper.
Windows
Clean the inside and outside surfaces of the
windows and the mirrors with window cleaner.
Do not clean the mirrors with cleaners
containing quartz.<
Paintwork care
Regular care contributes to value retention and
protects the paintwork against the long-term
effects of damaging substances.
Region-specific environmental influences can
damage the vehicle paintwork. Therefore, it is
important to adapt the frequency and scope of
car care accordingly.
Immediately remove aggressive materials such
as spilled fuel, oil, grease, brake fluid, tree sap or
bird droppings to prevent damage to the paint-
work.
Repairing paintwork damage
Immediately repair scratches or similar
damage, such as that caused by stones
hitting the vehicle, where necessary to prevent
rusting.<
BMW recommends having paintwork damage
repaired by a professional paint repair work-
shop according to BMW specifications using
original BMW paint materials.
Preservation
A preservation treatment is necessary when
water no longer beads off the clean paintwork
surface. Only use products for paintwork pres-
ervation that contain carnauba or synthetic
waxes.
Rubber seals
Treat only with water or rubber care products.
Do not use silicon-containing care prod-
ucts on rubber seals; otherwise, noise
and damage could occur.<
Chrome parts
Carefully clean vehicle parts such as the radia-
tor grill, door handles or window frames with
copious quantities of water and a shampoo
additive, especially when roads are treated with
deicing salt. For additional treatment, use
a chrome polish.
