2.The coolant level is correct when the
upper end of the red float is at least
even with the upper edge of the filler
neck but no more than 3/4 in/2 cm
above it, that is up to the second mark
on the float. Refer also to the schematic
diagram next to the filler neck
3.If necessary, add coolant. Slowly add
coolant until the correct level is
reached; do not overfill.
Comply with the applicable environ-
mental laws regulating the disposal of
antifreeze with corrosion inhibitor.<
Brake fluid
Indicator lamp
The brake warning lamp lights up
red when the parking brake is not
engaged: the brake fluid level is too
low, refer to page 69.
The brake warning lamp for Cana-
dian models lights up red when the
parking brake is not engaged: the
brake fluid level is too low, refer to page 69.
Brake fluid, refilling
Brake fluid loss may result in extended
brake pedal travel. If this occurs, also refer
to the notes on page 69.
Brake fluid is hygroscopic, that is, it
absorbs moisture from the air over
time.
In order to ensure the brake system's
safety and reliability, have the brake fluid
changed every two years by a BMW center.
Refer also to page 49 and the Service Man-
ual.
Brake fluid is toxic and damages the vehi-
cle's paint. You should always store it in the
closed original container and in a location
inaccessible to children.
Do not spill the fluid and do not fill the brake
fluid reservoir beyond the MAX mark. The
brake fluid could ignite upon contact with
hot engine parts and cause serious
burns.<
Comply with the applicable environ-
mental laws regulating the disposal of
brake fluid.<
Brake fluid level
Low brake fluid level in the reservoir com-
bined with extended pedal travel may indi-
cate a defect in one of the brake system's
hydraulic circuits.
BMW recommends that you proceed
to the nearest BMW center. Higher
brake application pressure may be neces-
sary under these conditions, and braking
distances may be significantly longer.
Please remember to adapt your driving
style accordingly.<

Laws and regulations
California Proposition 65
warning
California laws require us to state the fol-
lowing warning:
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the interior
furnishings in a vehicle, contain or emit
chemicals known to the State of California
to cause cancer and birth defects and
reproductive harm. In addition, certain flu-
ids contained in vehicles and certain prod-
ucts of component wear contain or emit
chemicals known to the State of CA to
cause cancer and birth defects or other
reproductive harm. Battery posts, terminals
and related accessories contain lead and
lead compounds. Wash your hands after
handling. Used engine oil contains chemi-
cals that have caused cancer in laboratory
animals. Always protect your skin by wash-
ing thoroughly with soap and water.<
OBD interface socket
The Onboard Diagnostic OBD interface
socket is located on the left of the driver's
side under the instrument panel and under
a cover.
The cover has the letters OBD on it.
The purpose of the OBD system is to
ensure proper operation of the emission
control system for the vehicle's lifetime. The system monitors emission-related
components and system for deterioration
and malfunction.
If the Service Engine Soon indicator
lamp comes on either continuously
or intermittently, this indicates a
fault in the emissions-related electronic
systems. Although the vehicle remains
operational, you should have the systems
checked by your BMW center at the earli-
est possible opportunity.
The illuminated indicator informs you of the
need for service, not that you need to stop
the vehicle. However, the systems should
be checked by your BMW center at the
next opportunity.
If the indicator blinks or flashes, this indi-
cates a high level of engine misfire. Reduce
speed and contact the nearest BMW center
immediately. Severe engine misfiring over
even a short period of time can seriously
damage emission control system compo-
nents, especially the catalytic converter.
Service Engine Soon warning lamp
for Canadian models.
If the gas cap is not on tight enough,
the OBD system can detect leaking
vapor and the indicator will light up. If the
gas cap is then tightened, the indicator will
usually go out after a short period of time.<

Low beams and high beams
Left side of engine compartment:
1Low beams
2High beams
H7 bulb, 55 watts
The H7 bulb is pressurized. There-
fore, wear safety glasses and protec-
tive gloves. Failure to comply with these
precautions could result in physical injury if
the bulb is damaged.<
1.Turn the bulb holder to the left and pull
out
2.Remove and replace the bulb
3.Install in the reverse order.
When cleaning the headlamps,
please observe the instructions in the
Caring for your vehicle brochure.<
Xenon lamps*
The service life of these bulbs is very long
and the probability of a failure is very low,
provided that they are not switched on and
off an unusual number of times. If one of
these bulbs should nevertheless fail, it is
possible to continue driving with great cau-
tion using the fog lamps, provided traffic
laws in your area do not prohibit this.
Because of the extremely high volt-
ages involved, any work on the xenon
lighting system, including bulb-changing,
should be carried out by technically quali-
fied personnel only. Otherwise, there is a
risk of fatal injury.<

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 page 80.
BMW recommends that you consult your
BMW center if you wish to replace the tires
of your BMW, or change from summer to
winter tires or vice versa.
Your BMW center knows how to work with
Run Flat tires and is equipped with the nec-
essary special tools.
When mounting or replacing summer
tires with winter tires, or vice versa,
use only Run Flat tires since no spare
wheel is available in the event of a flat.<
Jacking points
The jacking points are located at the posi-
tions indicated in the illustration.
Your BMW center can provide you
with a suitable jack.<
Battery
Maintenance
The battery is completely maintenance-
free. This means that the original electro-
lyte will normally last for the service life of
the battery under moderate climatic condi-
tions.
Please consult your BMW center
whenever you have any questions
concerning the battery.<
Indicator lamp
The indicator lamp for the battery
charge current lights up:
The battery is no longer being
charged. The alternator drive belt is defec-
tive 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 prevent overheating and serious engine
damage.
If the onboard supply voltage drops to a
very low level, increased steering effort
may also be necessary.<

Connecting jumper cables
Always adhere to this sequence when
connecting jumper cables; failure to
observe this procedure can lead to sparks
at the battery terminals and pose an injury
hazard.<
The auxiliary jump-starting terminal located
in your BMW's engine compartment acts as
the positive battery terminal. Refer to the
engine compartment overview on page 82.
The cover is marked with a +.
1.Open the cover of the BMW auxiliary
jump-starting terminal. Do so by pulling
the tab
2.With the + jumper cable, connect the
positive terminal of the drained battery
and the positive terminal of the support
battery.
To do this:
Connect one terminal clamp to the pos-
itive terminal of the battery or to an aux-
iliary jump-starting terminal of the sup-
port vehicle.
Connect the second terminal clamp to
the positive terminal of the battery or to
an auxiliary jump-starting terminal of
the vehicle to be jump-started.
Your BMW is equipped with a special
nut, refer also to the engine compart-
ment overview on page 823.With the – jumper cable, connect the
negative terminals of both vehicles.
To do this:
Attach one cable clamp to the negative
battery terminal or to a suitable ground
on the engine or body work of the sup-
port vehicle.
Attach the second cable clamp to the
negative battery terminal or to a suit-
able ground on the engine or body work
of the vehicle to be jump-started.
Starting the engine
1.Start the engine of the support vehicle
and let it run for several minutes at a
slightly elevated engine idle speed
2.Start the engine of the other vehicle as
usual.
If the first start attempt is not success-
ful, wait a few minutes before another
attempt in order to allow the discharged
battery to recharge.
3.Allow the engines to run for several
minutes
4.Then disconnect the jumper cables in
reverse sequence.
Depending on the cause of the fault, have
the battery checked and recharged by your
BMW center.
Never use spray starter fluids to start
the engine.<
