Warning of low tire inflation pressure
The warning lamp lights up in yellow. A
signal also sounds. There is a flat tire or
a significant loss of tire pressure in one
or more tires.
1.Cautiously reduce speed to 50 mph/
80 km/h or lower. Avoid strong braking and
steering maneuvers. Do not exceed a maxi-
mum speed of 50 mph/80 km/h.
If the car is not equipped with Run-
Flat Tires, which is the standard
equipment by design, refer to page88, then
do not continue driving. Doing so after a tire
puncture may result in a severe accident.<
2.In the event of complete tire pressure loss,
0 psi/0 kilopascal, you can estimate how far
you can continue driving on the basis of the
following guidelines:
>With a light load:
1 person without luggage:
approx. 155 miles/250 km
>With a medium load:
1 person, cargo bay full,
or
2 persons without luggage:
approx. 90 miles/150 km
>With a full load:
2 persons, cargo bay 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 reduced tracking stability in brak-
ing, extended braking distance and altered nat-
ural steering characteristics.
If unusual vibration or loud noises occur during
the journey, this may be an indication that the
damaged tire has finally failed. Reduce your
speed and pull over to the side of the road at a
suitable location at the earliest opportunity.
Otherwise, parts of the tire could come loose
and cause an accident. Do not continue driving.
Contact a BMW center.<
Malfunction
The yellow warning lamp flashes and
then lights up continuously. A flat tire
cannot be detected.
This warning is displayed under the following
circumstances:
>If there is a malfunction;
have the system checked.
>If a wheel without TPM electronics is
mounted.
>If other systems or devices that use the
same radio frequency temporarily interfere
with the TPM.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
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 inflation 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, you 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 illuminates a low tire pressure
telltale when one or more of your tires are signif-
icantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s han-
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-
inflation has not reached the level to trigger illu-
mination of the TPMS low tire pressure telltale.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain

triggering of the airbag restraint system, have
the testing, repair, removal, and disposal of air-
bag generators executed only by a BMW center
or a workshop that works according to BMW
repair procedures with correspondingly trained
personnel and has the required explosives
licenses. Unprofessional attempts to service
the system could lead to failure in an emer-
gency or undesired airbag activation, either of
which could result in personal injury.<
Warning notices and information about the air-
bags can also be found on the sun visors.
Automatic deactivation of the
passenger airbags
An analysis of the impression in the passenger
seat cushion determines whether and how the
seat is occupied. The front and side airbags for
the passenger are activated or deactivated by
the system accordingly.
The indicator lamp in the center console
shows the current status of the passen-
ger airbags, deactivated or activated, refer to
Status of passenger airbags below.<
Before transporting a child on the pas-
senger seat, observe the safety and han-
dling instructions under Transporting children
safely, refer to page36.
Adolescents and adults sitting in certain posi-
tions could inadvertently deactivate the front
and side airbags on the passenger side; the
indicator lamp for the passenger airbags comes
on. In such cases, the passenger should change
his or her sitting position so that the passenger
airbags are activated and the indicator lamp
goes out. If the passenger airbags cannot be
restored to the desired status despite the pas-
senger changing his or her seat position, use
the key switch to activate or deactivate the pas-
senger airbags, refer to page36. Do not attach
seat covers, seat cushion padding, ball mats or
other items to the 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. Otherwise a
correct analysis of the seat cushion is not
ensured.<
Status of passenger airbags
The indicator lamp for the passenger airbags
shows the functional status of the passenger's
front and side airbags in accordance with
whether and how the passenger seat is occu-
pied. The indicator lamp shows whether the
passenger airbags are activated or deactivated.
>The indicator lamp comes on as intended
when a child in an appropriate child-
restraint system is detected on the seat.
The front and side airbags for the passen-
ger are not activated.
>The indicator lamp does not come on 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 pas-
senger are activated.
>The indicator lamp does not come on if the
seat is empty. However, the front and side
airbags for the passenger are not activated.
Operational readiness of the airbag
system
With the ignition key in position 1 or higher, the
warning lamp comes on briefly to indicate that
the entire airbag system and the belt tensioners
are operational.

Airbag system malfunction
>Warning lamp does not come on with the
ignition key in position 1 or higher
>Warning lamp remains permanently on
In the event of a malfunction, have the air-
bag system checked immediately. Other-
wise, there is a risk that the system may not
respond in the expected manner to an impact
within its normal response range.<

Lamps
60 If necessary, switch on the parking lamps as
described in the section about parking lamps.
You can have the daytime running lamps
activated/deactivated on your vehicle.<
Pathway lighting
If you activate the headlamp flasher after park-
ing the car, with the lights switched off, the low
beams come on and remain on for a certain
time.
You can have this function activated/
deactivated as well as the duration of the
pathway lighting set.<
LIGHTS ON warning
Whenever you open the driver's door after hav-
ing turned the key to position 0, you will hear an
acoustic signal for a few seconds to remind you
that the lamps have not been switched off.

Roadside parking lamps, left or right*
When parking the vehicle, you have the option
to switch on the lamps only on the side facing
the road.
After parking the vehicle, press the lever up or
down, arrow 3, until it engages.
The roadside parking lamps discharge
the battery. Therefore, do not leave them
on for unduly long periods of time, otherwise the battery might not have enough power to
start the engine.<
Fog lamps*
Press the button to switch them on/off.
The parking lamps or low-beam headlamps
must be switched on. A green indicator lamp
comes on in the instrument cluster to indicate
that the front fog lamps are on.
If the automatic headlamp control is acti-
vated, the low beams will come on auto-
matically when you switch on the fog lamps.<
Instrument lighting
Turn the rotary dial to adjust brightness.

Special operating instructions
76 sure which must be exerted by the pads to
clean the rotors by brake applications is not
reached.
If the brake rotors are corroded, they will tend to
respond to braking with a pulsating effect which
even extended application will fail to cure.
Brake pads
The warning lamp lights up. The brake
pads have worn down to the minimum
safe limit. Have the brake pads
replaced as soon as possible.
When the vehicle is parked
Condensation forms while the air conditioning
or automatic climate control is in operation, and
then exits under the vehicle. Traces of con-
densed water on the ground underneath the
vehicle are thus normal.
Before driving into a car wash
For general information about taking care of
your BMW, refer to the Caring for your vehicle
brochure.
Cargo loading
Avoid overloading the vehicle so that the
permissible carrying capacity of the tires
is not exceeded. Otherwise, overheating and
inner damage to the tires may result. The ulti-
mate result can assume the form of a sudden air
loss.<
Determining the maximum load
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 passenger that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passenger 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
551 lbs and there will be two 150 lbs occu-
pants in your vehicle, the amount of avail-
able cargo and luggage load capacity is
251 lbs.
551 lbs minus 300 lbs = 251 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.

Refueling
82
Refueling
Always switch off the engine before refu-
eling. Otherwise the tank cannot be
refilled. The Service Engine Soon warning lamp
will come on.<
Take all precautionary measures and
observe all applicable regulations when
handling fuel. Do not carry any spare fuel con-
tainers in your vehicle. They can develop a leak
and cause an explosion or cause a fire in the
event of an accident.<
Gas cap
Opening
1.Open the fuel filler door, arrow 1.
2.Turn the gas cap counterclockwise.
3.Place the gas cap in the bracket attached to
the fuel filler door, arrow 2.
Closing
Fit the gas cap and turn it clockwise until you
clearly hear a click.
Do not jam the gas cap strap as this will
allow fuel vapors to escape.<
The warning lamp
* lights up briefly if
the gas cap is loose or missing. Close
the gas cap properly.
Manually releasing the fuel filler door
In the event of a malfunction you can unlock the
fuel filler door manually.1.Remove the cover for the right-hand rear
lamps in the cargo bay by turning the lock,
see arrow.
2.Pull the cargo bay trim panel slightly toward
the interior. The green button with the fuel
pump symbol becomes visible.
3.Undo the adhesive strip and pull off.
4.Pull the button. The fuel filler door is
released.
Pull on the button slowly and care-
fully; otherwise it could be torn off.<
Observe the following when refueling
When handling fuels, comply with all of
the applicable safety precautions posted
at the service station.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid lifting the filler
nozzle while filling the tank, as it could other-
wise lead to:
>Premature pump shutoff
>A reduced efficiency of the fuel-vapor
recovery system.

Wheels and tires
88 the letters TWI, for Tread Wear Indicator, on the
tire's sidewalls identify tires that incorporate
these wear indicators. Once the tire tread has
worn down to the wear indicators, the tire has
worn to a depth of 1/16 in/1.6 mm.
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 can, for
example, be caused by driving over curbs. The
same applies to any other abnormal road
behavior, such as pulling severely to the right or
left.
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. To do so, drive carefully to the
nearest BMW center or tire shop that works
according to BMW repair procedures with cor-
respondingly trained personnel. If necessary,
have the vehicle towed there.
Tire damage can be extremely dangerous for
vehicle occupants and other road users.<
Tire age
For various reasons, such as the development
of brittleness, BMW recommends tire replace-
ment after no more than 6 years, regardless of
the actual wear of the tires.
The date on which the tire was manufactured is
indicated by the code on the sidewall:
DOT … 5005 indicates that the tire was manu-
factured in week 50 of the year 2005.
Run-Flat Tires
The symbol identifying Run-Flat Tires is a circle
with the letters RSC on the sidewall.
Run-Flat Tires comprise a conditionally self-
supporting tire and a special rim. The reinforce-
ment in the sidewalls ensures that the tire can
continue to be used subject to certain restric-
tions, even if depressurized.
To continue driving with a damaged tire:
>If the vehicle is equipped with the Flat Tire
Monitor, refer to Flat tire warning on
page53.
>If the vehicle is equipped with the Tire Pres-
sure Monitor, refer to Warning of low tire
inflation pressure on page54.
Wheel and tire replacement
Have new wheels and tires installed only
by your BMW center or tire shop that
works according to BMW repair procedures
with correspondingly 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.<
Retreaded tires
BMW advises against using retreaded
tires, since driving safety may be
impaired. The causes for this include potentially
different tire casing structures and often wide
variations in tire age, which can result in a lim-
ited service life.<
