ControlsTechnology for driving comfort and safety
When driving with damaged tires, the handling
characteristics ch ange, e.g. the vehicle will skid
sooner when braking, braking distances will be
longer, or self-steerin g response will change.
Adapt your driving style accordingly. Avoid
turning abruptly and driving 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 driving style, can also be longer,
depending on the speed, road condition, out-
side temperature, vehicle load, etc.
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 while driving can
indicate complete fa ilure 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. <
Message for unsuccessful system
reset
Yellow warning lamp lights up. A
message appears on the Control Dis-
play.
The system has detected a wheel change, but
was not reset. A reliable warning is not possible
at the current inflation pressures.
Check the tire inflation pressure and reset the
system, refer to page 103.
Malfunction
The small warning lamp flashes in
yellow and then lights up continu-
ously; the large warning lamp lights
up in yellow. The tires appear in gray in the Control Display. No punctures can be
detected.
Display in the follo

> A wheel without TPM electronics has been
installed:
Have it checked by your BMW center.
> Malfunction
Have the system checked.
> Tire Pressure Monitor was unable to com-
plete the resetting process. Reset the sys-
tem again.

Tire Pressure Monitoring Systems
Each tire should be checked monthly when cold
and inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire infl ation pressure label. If
your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, yo u should determine the
proper tire inflation pressure for those tires. As
an added safety feature, your vehicle has been
equipped with a tire pressure monitoring sys-
tem, TPMS, that illuminate s a low tire pressure
telltale when one or more of your tires are signif-
icantly underinflated. Accordingly, when the
low tire pressure telltal e illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underi nflated tire causes the

ControlsTechnology for driving comfort and safety
The indicator lamp above the interior
rearview mirror shows the current status
of the front passenger airbags, deactivated or
activated, refer to Status of front passenger air-
bags below. <
Before transporting a child on the front
passenger seat, read the safety precau-
tions and handling inst ructions under Trans-
porting children safely, refer to page 57.
The front and side airbags can also be deacti-
vated by adolescents and adults sitting in cer-
tain positions; the indi cator lamp for the front
passenger airbags lights up. In such cases, the
passenger should change his or her sitting
position so that the fr ont passenger airbags are
activated and the indicator lamp goes out. If the
desired airbag status cannot be achieved by
changing the sitting position, transport the rele-
vant passenger on a rear seat. Do not attach
seat covers, seat cushion padding, ball mats or
other items to the front passenger seat unless
they are specifically recommended by BMW.
Do not place any items under the seat which
could press against the seat from below. Other-
wise, a correct analysis of the seat cushion is
not ensured. <
Status of front passenger airbags
The indicator lamp for the front passenger air-
bags shows the functional status of the front
passenger front and side airbags in accordance
with whether and how the front passenger seat
is occupied. The indicator lamp shows whether
the front passenger airbags are activated or
deactivated. >
The indicator lamp light s up when a child in
a specially designated child restraint sys-
tem is detected, as in tended, on the seat.
The front and side airbags for the front pas-
senger are not activated.
Most child seats are detected by the
system, This partic ularly applies to
child seats that were required by NHTSA at
the time of manufacture of the vehicle. After
mounting a child seat, ensure that the indi-
cator lamp for the fron t passenger airbag is
lit. It indicates that th e child seat has been
detected and that the front passenger air-
bags are deactivated. <
> The indicator lamp does not light up as long
as a person of sufficient size and in a correct
sitting position is detected on the seat.
The front and side airbags for the front pas-
senger are activated.
> The indicator lamp does not light up if the
seat is empty.
The front and side airbags for the front pas-
senger are not activated.
Operational readine ss of airbag system
As of radio readiness, refer to page 61, the
warning lamp lights up br iefly to indicate that
the entire airbag system and the belt tensioners
are operational.
Airbag system malfunction
> Warning lamp does not light up at radio
readiness or beyond.
> Warning lamp remains permanently on.

Vehicle equipment
In this chapter, all production, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehi
cle, for example due to
the special options or national-market version
selected. This also app lies to safety related
functions and systems.
Tire inflation pressures
Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on th e condition of the tires
and the maintenance of th e specified tire pres-
sure.
Check the tire inflation pressure regularly
and correct it, if nece ssary: at least twice a
month and before starting long trips. If you fail
to observe this precaution you may be driving
on tires with incorrect tire pressures, a condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age and the risk of an accident. Do not drive
with deflated, i.e. flat tires, except when using
run-flat tires. A flat tire will seriously impair your
vehicle's handling and braking response.
Attempts to drive on a flat tire can lead to loss of
control over the vehicle. <
Checking pressure
Only check tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure is higher.
After correcting the tire inflation pressure,
reset the Tire Pressure Monitor, refer to page
103, or reinitialize the Flat Tire Monitor,
refer to page 100.<
Inflation pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressure s apply to the tire
sizes approved and tire brands recom-
mended by BMW; a list of these is available
from your BMW center. <
For correct identification of the right tire infla-
tion pressures, observe the following:
> Tire sizes for your vehicle
> Maximum allowable driving speed
Tire inflation pressures for driving up to
100 mph or 160 km/h
For normal driving up to 100 mph or 160 km/h
and to achieve optimum driving comfort, adjust
pressures to the respecti ve tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds up to a maximum of
100 mph or 160 km/h.
These tire inflation pressures can also be found
on the driver's side door pillar when the driver's
door is open.
The maximum permissible speed for
these tire pressures is 100 mph or
160 km/h. Do not exceed this speed; otherwise,
tire damage and accidents could occur. <
