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 California
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 connector
The interface socket for the Onboard Diag-
nostic is located on the left of the driver's
side at the bottom of the instrument cluster
and under a cover. The cover has the let-
ters OBD on it.
The most important components for the
composition of the emissions can be
checked by a device across this interface. 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 Sports Activity
Vehicle Center at the earliest possible
opportunity.
The illuminated indicator lamp informs you
of the need for service, not that you need to
stop the vehicle. However, the systems
should be checked by your BMW Sports
Activity Vehicle Center at the next opportu-
nity.
If the indicator lamp blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact the nearest
BMW Sports Activity Vehicle Center imme-
diately. Severe engine misfiring over even a
short period of time can seriously damage
emission control system components,
especially the catalytic converter.
Service Engine Soon indicator lamp
for Canadian models.
If the fuel filler cap is not on tight
enough, the OBD system can detect
leaking vapor and the indicator lamp will
light up. If the fuel filler cap is then tight-
ened, the indicator lamp will usually go out
after a short period of time.<

Mounting compact wheel
1.Unscrew the lug bolts and remove the
wheel
2.Remove accumulations of mud or dirt
from the mounting surfaces of the
wheel and hub. Clean the lug bolts
3.Position the new wheel or compact
wheel. Secure the wheel by turning at
least two lug bolts into opposite bolt
holes
4.Screw in the remaining lug bolts.
Tighten all the bolts securely in a diag-
onal pattern
5.Lower the jack and remove it from
beneath the vehicle
6.Tighten the lug bolts in a diagonal pat-
tern
7.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 compact wheel or cor-
recting the inflation pressure, reinitialize
the Flat Tire Monitor, refer to page 53.
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 to
ensure that they are tightened to the spec-
ified torque of 101 lb ft/140 Nm as soon as
possible.<
Stow the defective wheel in the luggage
compartment.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
Replace the defective tire as soon as pos-
sible and have the new wheel/tire bal-
anced.
Driving with the compact wheel
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. Do not
deactivate DSC, as otherwise unstable
driving conditions may result.<
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 re-equipping to
wheels and tires of the original size as
quickly as possible.<
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.
Please contact your BMW Sports
Activity Vehicle Center with any ques-
tions concerning the battery.<
Do not disconnect the battery when
the engine is running. If you do so, the
ensuing voltage surge will damage the
vehicle's onboard electronics.<
Indicator lamp
The battery charge-current indica-
tor lamp lights up:
The battery is no longer being
charged. There is a defect on the alternator
V-belt or charge current circuit of the alter-
nator. Contact the nearest BMW Sports
Activity Vehicle Center.
Do not continue driving if the V-belt is
defective. The engine could be dam-
aged due to overheating.
Moreover, an increased amount of force is
required for steering if the onboard supply
voltage falls dramatically.<

Giving and receiving assistance
Receiving assistance
The Roadside Assistance of the BMW
Group offers you assistance in the event of
a breakdown around the clock, also at
weekends and on public holidays.
The phone numbers of the Roadside Assis-
tance control center in your home country
can be found in the BMW Dealer Directory.
In the case of vehicles with the corre-
sponding equipment, you can use buttons
in the headlining to contact Roadside
Assistance or start an emergency call.
When an emergency call is started, a tele-
phone connection is set up to the general
emergency call center.
In vehicles where BMW Assist is enabled,
the phone system will also automatically
establish contact with the BMW Assist
emergency call center. If the current loca-
tion of your vehicle can be determined, this
is transferred to the BMW Assist emer-
gency call center.
The condition for starting an emergency
call or contacting Roadside Assistance:
>The car phone is logged on to a mobile
telephone network
>The emergency call system is operable.
Starting an emergency call*
Press button, refer to arrow, for at least
2 seconds.
The indicator lamp above the buttons lights
up. As soon as the voice connection to the
general emergency number has been set up, the indicator lamp flashes.
If the indicator lamp flashes, but you are
unable to hear the emergency call center,
you can still be heard by the emergency
call center.
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.
Roadside Assistance*
Press button, refer to arrow, for at least
2 seconds.
The indicator lamp above the buttons lights
up. As soon as the voice connection to
Roadside Assistance has been set up, the
indicator lamp flashes.
On a country-specific basis, with BMW
Assist enabled, the current location of your
vehicle is determined at the same time.
