Adjustments
Safe seating position
For relaxed driving with as little fatigue as pos-
sible, you should select a seating position that
reflects your personal requirements. In combi-
nation with the safety belts and airbags, the cor-
rect seating position also plays an important
role in enhancing occupant safety in the event
of an accident. To ensure that the vehicle's
safety systems provide you with optimal pro-
tection, we request that you direct your careful
attention to the following section.
For supplementary information on transporting
children refer to page33.
Airbags
Always maintain an adequate distance
between yourself and the airbags. Always
hold the steering wheel by its rim with hands at
the 9 and 3 o'clock positions to minimize the
r i s k o f i n j u r i e s t o y o u r h a n d s o r a r m s i n t h e e v e n t
of airbag deployment.
Never allow any objects, individuals or animals
to obstruct the areas between passengers and
airbags.
Never use the front airbag's cover as a storage
tray or support for objects of any kind. Ensure
that the passenger is correctly seated, i.e. does
not prop feet or legs against the dashboard.
Otherwise, leg injury could result if the knee air-
bag and front airbag suddenly deployed.
Never let an occupant's head rest near or on a
side airbag because the inflating airbag could
cause a serious or fatal injury.<
Even when all these guidelines are observed,
the risk of injury as a result of contact with the
airbags cannot entirely be ruled out in some sit-
uations. In sensitive individuals, the ignition and
inflation noise may induce a mild hearing loss
that is temporary in most cases.
For airbag locations and additional information
on airbags, refer to page53.
Safety belts
Always fasten your safety belt before starting
off. As supplemental restraint devices, the air-
bags are designed to enhance the effective-
ness of the safety belts, and not to replace
them.
Your vehicle offers two sitting positions, each of
which is equipped with a safety belt.
At all times, occupants should sit upright
and be properly restrained: infants and
small children in appropriate child-restraint sys-
tems; larger children and adults using the safety
belts.
Expectant mothers should always wear their
safety belts, taking care to position the belt in
the pelvic area against the lower hips, where it
will not exert pressure against the abdomen.
N e v e r a l l o w m o r e t h a n o n e p e r s o n t o w e a r a si n -
gle safety belt. Never allow infants or small chil-
dren to ride in a passenger's lap.
Do not route the belt across your neck, or run it
across sharp edges. Be sure that the belt does
not become caught or jammed. Avoid twisting
the belt while routing it firmly across the hips
and shoulder; wear it as snugly against your
body as possible. Do not allow the belt to rest
against hard or fragile objects. Otherwise, the
belt in the pelvic area could slide over the hips in
the event of a frontal impact, leading to abdom-
inal injury. Avoid wearing bulky clothing and pull
the belt in the upper-body area upward periodi-
cally to retension it. Otherwise, the restraining
effect of the safety belt could be diminished.<
For information on using the safety belts, refer
to page30.

Brake force display
The Brake force display lights up in two stages
depending on how strongly you are braking.
>Normal braking:
The brake lamps and the center brake lamp

>Hard braking or braking with ABS:
In addition, the illuminated surface of the
brake lamps is extended, refer to the pic-
ture.
Flat Tire Monitor
The concept
As you drive, the Flat Tire Monitor keeps track
of pressure levels in all four tires. The system
alerts you whenever the inflation pressure of a
tire falls significantly below the pressure of
another tire.
In the event of tire pressure loss, the rolling
radius of the tire changes, thereby affecting the
rotational speed of the wheels. This change is
detected, and a flat tire warning is issued to the
driver.
System requirements
To ensure a reliable flat tire warning, the system
must be initialized with the correct tire inflation
pressures.
Each time you correct the pressure in a
tire, or change a wheel or tire, the system
must be re-initialized.<
System limitations
The Flat Tire Monitor cannot provide you
with advance warning of sudden and
severe tire damage caused by external factors
and does not detect the balanced and very
gradual pressure loss that takes place in all four
tires over an extended period of time.<
The system could issue a false warning or func-
tion in a delayed manner in the following situa-
tions:
>System was not initialized
>You are driving on a snow-covered or slip-
pery road surface
>Performance-oriented driving: slip at the
drive wheels, high levels of lateral accelera-
tion
>You are driving with snow chains.
Initializing the system
The initialization is completed while you
are driving, and can be interrupted at any
time. Initialization is automatically continued
when you continue driving.
When driving with snow chains, do not initialize
the system.<
1.Start the engine, but do not drive off
2.Press the button as long as you need to until
the yellow indicator lamp in the instrument
cluster lights up for a few seconds
3.Drive off.
Initialization is completed during the drive,
without any feedback issued.

Flat tire warning
The warning lamp in the instrument
cluster lights up in red. This visual alert
is accompanied by an acoustic warning
signal. There is a flat tire or a signficant loss of
tire pressure.
1.Carefully reduce your speed to under
50 mph / 80 km/h. Avoid strong braking and
steering maneuvers. Do not exceed a maxi-
mum speed of 50 mph / 80 km/h.
Do not continue driving if the vehicle
is not equipped with Run Flat tires,
refer to page82. If you continue to drive
with a flat tire, a serious accident could
result.<
2.Check the inflation pressure in all four tires
as soon as possible.
If the inflation pressure is correct in all
four tires, it is possible that the Flat
Tire Monitor was not initialized. In this case,
initialize the system.<
3.If there is a total loss of tire inflation pres-
sure, 0 psi/0 kilopascal, or obvious tire dam-
age, you can gauge the mileage for contin-
ued driving on the basis of the following
indications:
>With a light load:
1 person without luggage:
approx. 155 miles/250 km
>With a medium load:
1 person, luggage compartment full,
or
2 persons with luggage:
approx. 90 miles/150 km
>With a full load:
2 persons, luggage compartment full:
approx. 30 miles/50 km.
Drive cautiously. Do not exceed a speed
of 50 mph / 80 km/h. Driving characteris-
tics change if there is a loss of tire pressure.
This includes diminished track stability during
braking, longer braking distances and modified
steering. If unusual vibrations occur while driv-
ing, this can indicate a complete failure of the
damaged tire. Reduce your speed and pull over as soon as possible. Do not continue driving
and contact a BMW center.<
Malfunction
The indicator lamp in the instrument
cluster lights up yellow. The Flat Tire
Monitor is malfunctioning or out of
order. Have the system checked as soon as
possible.
Airbags
The following airbags are located under the
marked covers:
1Front airbags for driver and passenger
2Side airbags for driver and passenger
3Knee airbags for driver and passenger
Protective effect
Comply with the instructions on page27,
or the occupants' personal safety will be
diminished.<
The front airbags help protect the driver and
passenger in the event of a head-on collision
where the protection provided by the safety belt
alone would not be adequate. The side airbags
help provide protection in the event of a colli-
sion from the side. Each of the side airbags is
designed to help support the seat occupant's
upper body. The knee airbags help provide
additional protection in the event of a head-on
collision.
The airbags are deliberately not triggered in
every impact situation, e. g. not in less severe
accidents, certain roll-over conditions, or rear-
end collisions.

Tire inflation pressure
Information for your safety
It is not merely the tire's service life, but also
driving safety and driving comfort that largely
depend on the condition of the tires and the
maintenance of the specified tire pressure.
Checking tire pressures
Check the tire inflation pressures only when the
tires are cold. This means after a maximum driv-
ing distance of 1.25 miles/2 km or if the vehicle
has been parked for at least 2 hours. Warm tires
have higher inflation pressures.
Check tire inflation pressures regularly
and correct them if necessary: at least
every two weeks and before every extended
journey. Otherwise, incorrect tire pressures can
cause driving instability or tire damage, ulti-
mately resulting in accidents.<
Reinitialize the Flat Tire Monitor after cor-
recting the tire inflation pressure. Refer to
page52.<
Inflation pressures for original tires
The specified inflation pressures for tires at
ambient temperature are provided on the plac-
ard on the B-pillar and are visible when the
driver's door is open.
Inflation pressures for other tire sizes
The following tire inflation pressure tables show
the inflation pressures for the specified tire
sizes at ambient temperature.To determine the correct tire inflation
pressure for your tires, observe the pres-
sures listed for the relevant tire sizes.<
Tire size
The inflation pressures in the table apply to
BMW-approved tire sizes and recommended
tire brands. Your BMW center will be glad to
supply this information.

Temperature
The temperature grades are A, the highest, B
and C, representing the tire’s resistance to the
generation of heat and its ability to dissipate
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,
under-inflation, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.<
RSC: Run Flat tires
Run Flat tires are labeled on the sidewall with a
circular symbol containing the letters RSC.
Refer to page82.
M+S
Winter and all-season tires.
These have better winter performance proper-
ties than summer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Tire tread
Tread depth should not be allowed to go below
1/8 in / 3 mm even though in Europe, for exam-
ple, the legally specified minimum tread depth
is only 1/16 in / 1.6 mm. Below 1/8 in / 3 mm
tread depth, there is a very high risk of hydro-
planing, even with only small amounts of water
on the road and at relatively moderate speeds.At tread depths below approx. 1/6in/ 4mm,
winter tires display a perceptible decrease in
their ability to cope with winter driving condi-
tions, and should be replaced in the interest of
safety.
Tread wear indicators in the tread-groove base,
see arrow, are distributed around the wheel cir-
cumference and are labeled on the tire sidewall
as TWI, Tread Wear Indicator. At a tread depth
of 1/16 in / 1.6 mm, the indicators signal that the
legally permissible wear limit has been reached.
Wheel/tire damage
Due to low-profile tires, please note that
wheels, tires and suspension parts are
more susceptible to road hazards and conse-
quential damages.<
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle malfunction. This type of
problem can be caused by contact with curbs,
etc. This is also true for irregularities in the vehi-
cle's handling characteristics, such as a pro-
nounced tendency to pull to the left or right.
Should this occur, respond by immedi-
ately reducing your speed. Proceed care-
fully to the nearest BMW center or professional
tire center, or have the vehicle towed there.
Tire damage up to and including sudden and
complete air loss can pose an extreme hazard
for both vehicle occupants and other road
users.<

Wheels and tires
82
Run Flat tires fitted
Run Flat tires are labeled on the sidewall with a
circular symbol containing the letters RSC.
Run Flat tires consist of self-supporting tires
and special rims. The tire reinforcement
ensures that driving remains possible to a
restricted degree in the event of pressure drop
or even if the tire is deflated.
Wheel and tire replacement
Have new wheels and tires mounted only
by a BMW center or specialized tire shop
that works according to BMW requirements
with the appropriately trained personnel. Work
that is improperly carried out could result in
consequential damage and pose safety haz-
ards. Make sure that the new wheels are bal-
anced.<
BMW advises against using retreaded
tires, since driving safety may be
impaired. This is due to possible variations in
casing structures and, in some cases, to their
extreme age, factors which can lead to a
decrease in their durability.<
The correct wheels and tires
BMW recommends using only wheels
and tires that have been approved by
BMW for your particular vehicle model, as oth-
erwise body contact and serious accidents can
result despite the use of the same nominal size,
e.g. due to manufacturing tolerances. If non-
approved wheels and tires are used, BMW can-
not evaluate their suitability, and therefore can-
not be held liable for driving safety.
nations for your vehicle.
The correct wheel and tire combination also
affects other systems which would otherwise
be impaired, for example ABS or DSC.
To maintain good handling and vehicle
response, use only tires of a single brand and
tread configuration. In the event of a flat tire,
remount the previous wheel and tire combina-
tion as soon as possible.
Recommended tire brands
BMW tests certain tire brands for each tire size,
classifies them as road-safe and approves
them. You can best find out about these at a
specialized shop, particularly your BMW center.
Observe any country-specific regulations, e.g.
on making a corresponding entry in the vehicle
documents.
The factory-approved radial-ply tires are
matched to your vehicle and have been
selected to provide optimum safety and driving
comfort when used properly.
Run Flat tires
When mounting new tires or replacing summer
tires with winter tires, or vice versa, use Run Flat
tires since no spare wheel is available in the
event of a flat. Your BMW center will be glad to
provide you with more information.
For safety reasons, BMW recommends to
have Run Flat tires replaced, not repaired,
if they are damaged.<
Special characteristics of winter tires
BMW recommends the use of winter tires for
operation under winter road conditions. While
all-season tires with M+S designation provide
better winter traction than summer tires, they
generally do not achieve the full performance of
winter tires.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated. Unpro-
fessional attempts by laymen to service tires

can lead to damage and accidents. Have this
work performed by skilled professionals only.
The technicans at your BMW center will be glad
to assist you with the required professional
knowledge and specialized equipment.<
Storage
Store tires in a cool, dry place, protecting them
against light whenever possible. Protect the
tires from contact with oil, grease and fuel. Do
not exceed the maximum tire inflation pres-
sures specified on the tire sidewall.
Snow chains*
Only certain types of snow chains have been
tested by BMW, classified as road-safe and
approved. Consult your BMW center for more
information. BMW recommends using only
approved fine-link snow chains. Use them in
pairs on either summer or winter tires, but only
on both rear wheels.
Comply with all manufacturer's safety precau-
tions when mounting the chains.
Do not exceed a speed of 30 mph / 50 km/h
when using snow chains.
Do not initialize the Flat Tire Monitor after
snow chains have been mounted.
When driving with snow chains, it may be useful
to deactivate the DSC briefly. Refer to
page51.<

function.
License plate lamps
5 watt bulb
1.Push out the lamp with a suitable object and
remove it
2.Replace the bulb.
Snap the lamp back into place.
Light-emitting diodes LEDs
Control elements, display units and other inte-
rior equipment in your vehicle use a light-emit-
ting diode behind a cover as a light source.
These light-emitting diodes are similar to con-
ventional lasers.
Do not remove the covers, and do not
look directly at the unfiltered light for sev-
eral hours. Otherwise, it can lead to retinal irrita-
tion of the eye.<
Changing a wheel
Run Flat tires
Your BMW is equipped with Run Flat tires.
Therefore, the wheel no longer has to be
changed immediately in the event of a loss in
inflation pressure.
Run Flat tires are labeled on the sidewall with a
circular symbol containing the letters RSC.
Refer to page82.
BMW recommends that you consult your BMW
center if you wish to replace the tires of your
B MW , o r change from summe r to winter tire s o r
vice versa.
Your BMW center knows how to work with Run Flat tires and is equipped with the necessary
special tools.
When mounting or replacing summer
tires with winter tires, or vice versa, use
only Run Flat tires since no spare wheel is avail-
able in the event of a flat.<
Jacking points
The jacking points are located at the positions
indicated in the illustration.
Your BMW center can provide you with a
suitable jack as an accessory.<
Vehicle battery
Maintenance
The battery is completely maintenance-free.
This means that the original electrolyte will nor-
mally last for the service life of the battery under
moderate climatic conditions. Your BMW cen-
ter will be happy to advise you if you have any
questions concerning the battery.
Indicator lamp
The indicator lamp lights up:
The battery is no longer being charged.
The alternator drive belt is defective or
there is a malfunction in the charging circuit of
the alternator. Please contact the nearest BMW
center.
If the drive belt is defective, pull over and
switch off the engine immediately to pre-
vent overheating and serious engine damage.
If the onboard supply voltage drops to a very
low level, increased steering effort may also be
necessary.<
