Malfunction
The warning lamp for the brake system
lights up in yellow. The drive-off assis-
tant has failed. The car will not be held
in place after the brake is released. Have the
system checked as soon as possible.
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor monitors tire pressures
while the car is being driven. The system
reports any significant loss of pressure in one
tire in relation to another.
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.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy 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
>Driving on a snow-covered or slippery road
surface
>Performance-oriented driving: slip at the
drive wheels, high levels of lateral accelera-
tion
>Driving with snow chains attached
Initializing the system
The initialization is completed while you
are driving, and can be interrupted at any
time. Initialization is continued automatically
when you continue driving.
When driving with snow chains, do not initialize
the system.<
1.Start the engine immediately before pulling
away, but do not drive off yet.
2.Press the button 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. A signal also
sounds. There is a flat tire or a signifi-
cant loss of tire pressure.
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, refer to page88, the stan-
dard equipment by design, do not continue
driving. Otherwise a severe accident could
result after a tire puncture.<
2.At the next opportunity, check the air pres-
sure in all four tires.
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.<

Technology for driving comfort and safety
54 3.In the event of complete tire pressure loss,
0 psi/0 kilopascal, you can estimate the
possible distance for continued 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 the
earliest opportunity. Otherwise, parts of the tire
could come loose and cause an accident. Do
not continue driving. Contact a BMW center.<
Tire Pressure Monitor TPM*
The concept
TPM monitors the tire inflation pressure in all
four mounted tires. The system reports if infla-
tion pressure has dropped significantly in one
or more of the tires.
System requirements
To ensure a reliable flat tire warning, the system
must have been reset while tire inflation pres-
sures were correct.
Always use tires with TPM electronics to
ensure that the system operates properly.The system must be reset each time a tire
inflation pressure has been corrected or a
wheel or tire has been changed.<
System limitations
TPM cannot report sudden serious tire
damage due to external causes.<
The system will not operate correctly if it was
not reset, e.g. it may report a flat tire even if the
tire inflation pressures are correct.
The system is inactive and cannot indicate a flat
tire if a wheel without TPM electronics is
mounted or if other systems or devices that use
the same radio frequency temporarily interfere
with the TPM system.
Resetting the system
The system must be reset each time a tire
inflation pressure has been corrected or a
wheel or tire has been changed.<
1.Start the engine but do not drive off yet.
2.Press the button until the yellow warning
lamp in the instrument cluster lights up for a
few seconds.
3.Drive off.
After several minutes of driving, the current
inflation pressures in the tires are adopted
as the target values to be monitored. The
resetting procedure is completed automat-
ically without further notice during the trip,
which can be interrupted at any time.
Resetting is continued automatically when
you continue driving.

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

* and daytime
running lamps
*
When you park the car, all its outside lamps are
switched off automatically if the light switch is in
position0, 2 or 3.
If you want the parking lamps to be on, turn the
switch to position1.
Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps to signal the position of the vehi-
cle when it is parked. For the additional option
of roadside parking lamps on one side of the
vehicle only, refer to page60.
The parking lamps will discharge the bat-
tery. Therefore, do not leave them on for
unduly long periods of time, otherwise the bat-
tery might not have enough power to start the
engine.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
Defective bulb
The indicator lamp lights up:
At least one bulb of the vehicle's exte-
rior lighting has failed.
For replacing bulbs refer to page98.
Automatic headlamp control*
When the switch is in position3, the low beams
are switched on and off automatically depend-
ing on ambient light conditions, e.g. in a tunnel,
in twilight, or if there is precipitation.
When driving into tunnels with bright overhead
lights, there may be a delay before the head-
lamps come on.
The headlamps may also come on when the
sun is sitting low on a blue sky.
The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps
*.<
If desired, the light switch can remain in
position3. The exterior lamps are automatically
switched off after the vehicle is parked.
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the system
cannot detect fog or hazy weather. To avoid
safety risks, you should always switch on the
lamps manually under these conditions.<
You can have the sensitivity of your vehi-
cle's automatic headlamp control
adjusted.<
Daytime running lamps*
If desired, the light switch can remain in the
automatic headlamp control position. The exte-
rior lamps are automatically switched off after
the vehicle is parked.
In the Parking lamps position, the parking lamps
come on after the ignition is switched off.

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

Climate
66
Comfortable interior climate
AUTO program 6 offers the ideal air distribution
and air flow rate for almost all conditions, refer
to AUTO program below. In addition, you can
select an interior temperature you find pleasant.
The following sections inform you in detail
about how to adjust the settings.
Air distribution, manual
Direct the flow of air to the windows
, to the upper body area and to
the footwell . Intermediate settings
are possible. The arrow lights up.
The automatic air supply remains unchanged.
You can switch the automatic air distribution
back on by pressing the AUTO button.
Defrosting windows and removing
condensation
Quickly removes ice and condensa-
tion from the windshield and side
windows.
AUTO program
The AUTO program adjusts the air
distribution to the windshield and
side windows, towards the upper
body area and into the footwell for
you. The air flow rate and your temperature
specifications will be adapted to outside influ-
ences as a result of seasonal changes, e.g. sun-
light or window condensation.
The cooling is switched on automatically with
the AUTO program.
The AUTO program functions only to a
limited extent when the convertible top is
open.<
Air flow rate, manual
Adjust the air flow rate. The arrow
lights up.
The automatic air distribution
remains unchanged. You can reactivate the
automatic mode for the air flow rate with the
AUTO button.The higher the air flow rate, the more effective
the air conditioning will be.
Switching the system on/off
Turn the rotary switch to 0. The automatic cli-
mate control is switched off and the air supply is
cut off.
To switch on the automatic climate control, set
any desired air flow rate.
Switching cooling function on/off
When the cooling function is on, the
air is cooled, dehumidified, then
reheated depending on the tempera-
ture setting.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is automatically switched
on along with the AUTO program. The passen-
ger compartment can only be cooled while the
engine is running.
Maximum cooling
At outside temperatures above
327/06 and when the engine is
running, you obtain a maximum cool-
ing effect as soon as possible.
The automatic climate control switches to the
lowest temperature and operates in recircu-
lated-air mode. Air flows at maximum rate only
from the vents for the upper body area. You
should therefore open them for maximum cool-
ing.
Temperature
Set the desired temperature.
The values on the dial are approxima-
tions of the respective temperature
resulting in the passenger compartment.
The automatic climate control achieves this
temperature as quickly as possible regardless
of the season, using maximum cooling or heat-
ing power if necessary, and then maintains it.
If you switch between different tempera-
ture settings in quick succession, the

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.
