Checking coolant level
Correct coolant level with the engine cold,
approx. +687/206:
1.Turn the cap of the expansion tank
counterclockwise to allow any accumu-
lated pressure to escape, then continue
turning to open
2.The coolant level is correct when the
coolant extends to between the MIN
and MAX marks on the filler neck, refer
to the diagram adjacent to the filler
neck
3.If the coolant is low, slowly add coolant
up to the specified level Ð do not overfill.
Brake fluid
The symbol lights up and a mes-
sage appears on the Control Dis-
play: the brake-fluid level in the
container is too low.
The brake fluid reservoir is located under
the microfilter housing trim panel on the
driver's side of the vehicle. To have brake
fluid added to the system, or to have the
source of any brake fluid loss traced and
rectified, please contact your BMW center,
which can also supply the factory-
approved Ð DOT 4 Ð brake fluids.
Brake fluid is hygroscopic: it absorbs
moisture from the atmosphere over
the course of time.
To ensure that the brake system continues
to provide safe and reliable performance,
remember to have the brake fluid changed
every 2 years at the latest, refer to page 66
and to the Service and Warranty Informa-
tion Booklet for US models or the Warranty and Service Guide Booklet for Canadian
models.
Brake fluid is toxic and also damages vehi-
cle paintwork. Always store these agents in
tightly-closed original containers kept well
away from the reach of children.
Do not spill the fluid and do not refill the
brake fluid reservoir to beyond the MAX
mark. Should it come into contact with hot
engine components, the brake fluid could
ignite and cause personal injury in the form
of burns.<
Always observe all applicable rules
and regulations for environmental
protection when disposing of used brake
fluid.<
Warning lamp for Canadian models.
Brake hydraulic systems
A low brake-fluid level combined with
longer-than-usual pedal travel could be a
sign that one of the brake system's hydrau-
lic circuits has failed.
Proceed to the nearest BMW center.
Remember that pedal travel may be
increased, and there may also be a sub-
stantial increase in the amount of pedal
pressure required to brake the vehicle.
Please adapt your driving style accord-
ingly.<

Rules and regulations
California Proposition 65
Warning
California laws require us to issue 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 California
to cause cancer and birth defects or other
reproductive harm.
Battery posts, terminals and related acces-
sories contain lead and lead compounds.
Wash your hands after handling.
Used engine oil contains chemicals that
have caused cancer in laboratory animals.
Always protect your skin by washing
thoroughly with soap and water.<
OBD connector
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 emissions-related
components and systems for deterioration
and malfunction.
An illuminated indicator lamp
informs you of the need for service,
not of the need to stop the vehicle.
However, the systems should be checked
by your BMW center at the earliest possible
opportunity.
Indicator lamp for Canadian mod-
els.
Under certain conditions, the indicator will
blink or flash. This indicates a rather severe
level of engine misfire. When this occurs,
you should reduce speed and consult the
nearest BMW center as soon as possible.
Severe engine misfire over only a short
period of time can seriously damage emis-
sions control components, especially the
catalytic converter.
When the fuel filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator
lamp will light up. If the filler cap is subse-
quently tightened, the indicator lamp
should go out within a few days.<

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.
In the unlikely event that one of these
lamps should fail, you can respond by
switching on your fog lamps and proceed-
ing carefully, where allowed by law.
To avoid the risk of potentially fatal
injuries: owing to the extremely high
voltages at which these units operate, ser-
vice work on the xenon lighting system
should always be entrusted to qualified
personnel.<
Parking and standing lamps
Please contact a BMW center in case of a
malfunction.

Replacing components
188 3.Loosen the lug bolts 1/2 a turn
4.Set up the jack beneath the jacking
point closest to the flat tire. Ensure that
the entire surface of the jack's base is in
firm contact with the ground and that
the jack itself is standing completely
vertical, not tilted, and that the fitting on
the top of the jack will align with the
rectangular recess on the vehicle when
you raise it, refer to illustration
5.Jack the vehicle up until the wheel you
are changing is raised from the ground
6.Unscrew the lug bolts and remove the
wheel
7.Remove accumulations of mud or dirt
from the mounting surfaces of the
wheel and hub. Clean the lug bolts
8.Position the new wheel or compact
wheel. Secure the wheel by turning at
least two lug bolts into opposite bolt
holes
9.Screw in the remaining lug bolts.
Tighten all the bolts securely in a diag-
onal pattern
10.Lower the jack and remove it from
beneath the vehicle
11.Tighten the lug bolts in a diagonal pat-
tern
12.Check and correct the tire inflation
pressure at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
After mounting the wheel or correcting the
inflation pressure, reinitialize the Flat Tire
Monitor, refer to page 81.The vehicle jack is designed for
changing wheels only. Do not attempt
to raise another vehicle model with it or to
raise any load of any kind. To do so could
cause accidents and personal injury.
To ensure safety, always have the lug bolts
checked with a calibrated torque wrench
as soon as possible to ensure that they are
tightened to the specified torque.
The tightening torque is 120 Nm.<
Reverse the removal sequence to store the
wheel and tools in the vehicle.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
Always have damaged tires replaced and
the wheel and tire assembly rebalanced at
the earliest possible opportunity.
Driving with the compact wheel
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h.
The driving characteristics change, for
example reduced track stability on braking,
extended braking distance, and altered
self-steering characteristics in the limit
range. In conjunction with winter tires,
these characteristics are more pro-
nounced.
Only one compact wheel may be
mounted. You should fit wheels and
tires of the original size as quickly as possi-
ble.<
Battery
Battery care
The battery is 100% maintenance-free, i.e.,
the electrolyte will last for the life of the bat-
tery when the vehicle is operated in a tem-
perate climate.
For all questions that regard the bat-
tery, please consult your BMW cen-
ter.<

Starting an emergency call*
Conditions for an emergency call:
>The car phone is logged on to a porta-
ble phone network
>The emergency call system is operable.
To start an emergency call:
1.To open the cover flap:
Briefly press the cover flap
2.Press the button for at least 2 seconds.
The indicator lamp in the button lights
up. As soon as the voice connection to

You will then be able to provide a detailed
description of the situation.
In vehicles where BMW Assist is enabled,
the phone system will automatically estab-
lish contact with the BMW Assist emer-
gency call center. If the current position of
your vehicle can be determined, this is
transferred to the BMW Assist emergency
call center.Activating BMW Assist, refer to page 161.
If the navigation system fails, the cur-
rent position of the vehicle is not
transmitted.<
If the indicator lamp flashes, but you are
unable to hear the emergency call center
through the hands-free system, this could
indicate, for instance, that the hands-free
system is no longer operational. However,
the emergency call center can still hear
you.
For technical reasons, the emergency
call cannot be guaranteed under
unfavorable conditions.<
Under certain conditions, an emergency
call is started automatically immediately
after a severe accident. The automatic
emergency call is not affected by the but-
ton being pressed.
