Report of a flat tire
The warning lamp lights up in red. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden brak-
ing and steering maneuvers. Do not exceed
a vehicle speed of 50 mph/80 km/h.
If the vehicle is not, as provided at the
factory, equipped with run-flat tires,
refer to page172, stop driving. Continued
driving after a flat tire can result in serious
accidents.<
2.Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized.<
3.In case of a complete loss of the tire inflation
pressure or obvious tire damage, you can
estimate the possible driving distance for
continued driving base on the following ref-
erence values:
>With low load:
1 to 2 persons without luggage:
approx. 155 miles/250 km.
>With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 94 miles/150 km.
>With full load:
4 persons, luggage compartment full:
approx. 30 miles/50 km.
Drive reservedly and do not exceed
a speed of 50 mph/80 km/h. In the
event of pressure loss, vehicle handling
changes. This includes reduced tracking
stability in braking, extended braking dis-
tance and altered natural steering charac-
teristics.
If unusual vibrations occur while the vehicle
is being driven, this can indicate final failure
of the damaged tire. Reduce speed and stop as soon as possible. Do not continue
driving. Contact your BMW center.<
Malfunction
The warning lamp lights up in yellow. A
message appears on the Control Dis-
play. The Flat Tire Monitor has a mal-
function or has failed. Have the system checked
as soon as possible.
Active steering*
The concept
The active steering is a system that actively var-
ies the steering angle of the front wheels in rela-
tion to the steering wheel movements.
A t l o w s p e e d , e . g . i n a t o w n o r w h e n p a r k i n g , t h e
steering angle of the wheels is reinforced, i.e.
the steering becomes very direct.
In the higher speed range, on the other hand,
the steering angle is reduced more and more.
This improves the handling capability of your
BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stability-pro-
moting intervention is deactivated when DSC is
switched off, refer to page82.
Malfunction
The warning lamp lights up. The active
steering is no longer operational. At low
speed, larger steering wheel move-
ments are required, while the vehicle reacts
more sensitively to steering wheel movements
in the higher road-speed range. Have the sys-
tem checked.
If the warning lamp lights up during the first
engine starting following a power supply inter-
ruption, the system must be activated by being
initialized.

heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
RSC – run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page172.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and foreign objects lodged in
the tread, and check the tread depth.
Minimum tread depth
The tread depth should not drop below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm.
At tread depths below 0.12 in/3 mm there is an
increased risk of high-speed hydroplaning,
even when only small amounts of water are
present on the road surface.
Winter tires noticeably loose their suitability for
winter use below a tread depth of 0.16 in/4 mm. New tires should be mounted in the interest of
safety.
Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the indica-
tors are at the level of the profile, the legal per-
missible tread depth of 0.063 in/1.6 mm has
been reached.
Tire damage
Due to low-profile tires, please note that
wheels, tires and suspension parts are
more susceptible to road hazard and conse-
quential damages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases reduce your speed immediately
and have the wheels and tires inspected imme-
diately. To do this, carefully drive to the next
BMW center or a specialized tire dealer which
works with personnel trained in accordance
with BMW specifications. Have the vehicle
towed to the workshop if necessary.
Tire damage can be extremely dangerous to
vehicle occupants and other road users.<
Unprofessional attempts by laymen to
service tires can lead to damage and acci-
dents. Have this work performed by skilled pro-
fessionals only. The technicians at your BMW
center will be glad to assist you with the
required professional knowledge and special-
ized equipment.<

3.Remove and replace the bulb.
LEDs Light-emitting diodes
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers, and never
stare into the unfiltered light several
hours, as irritation of the retina could result.<
Changing a wheel
Your BMW is equipped with run-flat tires as
standard. An immediate wheel change in the
event of a flat tire is therefore no longer
required.
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to Run-flat tires on page171.
If you have new tires mounted or switch from
summer to winter tires, or vice versa, use run-
flat tires, as in the event of a flat tire there is no
spare tire available. Your BMW center will be
glad to advise you.
Also refer to New wheels and tires, page172.
Car jacking points
The jacking points for the car jack are located in
the positions shown.
The suitable tools for changing tires are
available as accessories from your BMW
center.<
Vehicle battery
Battery care
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate.
Your BMW center will be glad to advise in all
matters concerning the battery.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. For the connections, refer
to Jump starting on page186.
Disposal
After replacement, have old batteries dis-
posed of by your BMW center or deposit
them at a recycling center. Maintain the battery
in an upright position for transport and storage.
Always secure the battery to prevent it from tip-
ping over during transport.<
