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

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.

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

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,

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.

1 liter of engine oil until the warning lamp lights
up in the instrument cluster, refer to page92, or
until the oil level monitor shows "+1.0".
Add oil within the next 125 miles/200 km,
otherwise the engine could be dam-
aged.<
Keep oils, greases, etc. out of the reach of
children and comply with the warnings on
the containers. Otherwise, health hazards may
result.<
Oil change
Have your oil changed only by a BMW center or
a workshop that works according to BMW
requirements with the appropriately trained
personnel.
Approved engine oils
The quality of the engine oil is extremely impor-
tant for the function and life of an engine. BMW
continuously approves specific oils after con-
firming their suitability for use in its vehicles
with extensive testing.
Only use approved BMW High Performance
Synthetic Oil.
If BMW High Performance Synthetic Oil is not
available, you can add small quantities of other
synthetic oils in between oil changes. Only use
oils with the API SH specification or higher.
Your BMW center will be glad to answer
any questions regarding BMW High Per-
formance Synthetic Oil or other approved syn-
thetic oils. 1-800-831-1117 or visit the website
www.bmwusa.com to obtain this information.
Do not use any oil additives, as they could
cause engine damage under some cir-
cumstances.<
Viscosity classes
Viscosity is a measure of an oil's flow rating and
is categorized in SAE classes.
Selecting the appropriate SAE class depends
on the regional climatic conditions in which you
normally drive your BMW.
Approved oils belong to the 5W-40 and
5W-30 classes.<
These oils can be used for driving at all outside
temperatures.
Coolant
Warning lamp
The warning lamp lights up:
The coolant level is too low. Top up the
coolant as soon as possible.
Do not open the cooling system when the
engine is hot. If you do, escaping coolant
can cause burns.<
Coolant consists of water and coolant additives.
Not all commercially available additives are suit-
able for your BMW. Your BMW center knows
which additives are appropriate.
Only use approved additives, otherwise
the engine could be damaged. The addi-
tives are hazardous to health.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking the coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated

3.The coolant level is correct if the upper end
of the red float spindle is at least at the same
level as the upper edge of the filler neck but
no more than 3/4 in or 2 cm above it, i.e. up
to the mark on the float spindle. Refer also
to the diagram next to the filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5.Twist the cap back on and tighten it firmly.
6.Have the cause for the coolant loss
removed as soon as possible.
