Fuel specifications
Do not use leaded gasoline; otherwise,
permanent damage to the catalytic con-
verter will result.<
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with a
lower AKI rating. The minimum AKI rating is 87.
If you use gasoline with this minimum AKI rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10Ξ ethanol or other
oxygenates with up to 2.8Ξ oxygen by weight,
that is, 15Ξ MTBE or 3Ξ methanol plus an
equivalent amount of co-solvent, will not void
the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
drivability, starting and stalling problems,
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may result in unscheduled maintenance.<

Wheels and tires
Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance
of the specified tire pressure are crucial not only
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
Checking pressure
Only check tire inflation pressure when the tires
are cold. This means after a maximum of
1,25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure increases.
Check the tire inflation pressure regularly
and correct it as needed, including the
spare wheel: at least twice a month and before
starting long trips. If you fail to observe this pre-
caution, you may be driving on tires with incor-
rect tire pressures, a condition that can not only
compromise your vehicle's driving stability, but
also lead to tire damage and the risk of an acci-
dent. Do not drive with deflated, i.e. flat tires,
except run-flat tires. A flat tire will seriously
impair your vehicle's handling and braking
response. Attempts to drive on a flat tire can
lead to loss of control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor, refer to
page90, or reset the Tire Pressure Monitor,
refer to page92.<
Pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire
sizes and tire brands respectively
approved and recommended by BMW; a list of
these is available from your BMW center. pressure for your tires, observe the following:
>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving
up to 100 mph/160 km/h
For normal driving up to 100 mph/160 km/h
adjust pressures to the respective tire inflation
pressures listed on the following pages in the
column for traveling speeds up to a max. of
100 mph/160 km/h to achieve optimum driving
comfort.
These pressure specifications can be found on
the door post when you open the driver's door.
The permissible top speed for these tire
inflation pressures is 100 mph/160 km/h.
Do not exceed this speed; otherwise, tire dam-
age and accidents may result.<
Tire inflation pressures for driving
above 100 mph/160 km/h
In order to drive at maximum speeds in
excess of 100 mph/160 km/h, please
observe, and, if necessary, adjust tire pressures
for speeds exceeding 100 mph/160 km/h from
the relevant table on the following pages.
Otherwise, tire damage and accidents could
occur.<
Observe all national and local maximum speed
limits; otherwise, violations of the law could
occur.

The BMW Maintenance
System
The BMW Maintenance System serves to
retain the operating and road safety of your
BMW. The service schedule also includes oper-
ations related to the vehicle's comfort and con-
venience features, such as replacement of the
filters for the inside air. The aim is to optimize
maintenance procedures with a view to reduc-
ing the cost of running the vehicle.
Should the day come when you decide to sell
your BMW, you will find that a complete dealer
service history is an asset of inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. As a result, Condition Based Service
determines the current and future maintenance
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system forms
the basis for trouble-free driving.
You can have the remaining times or distances
to selected maintenance requirements as well
as legally required deadlines displayed on the
Control Display, refer to page78:
>Engine oil
>Brakes, separate for front and rear
>Microfilter
>Brake fluid
>Spark plugs>Vehicle check
>Legally prescribed inspections depending
on national regulations
Your vehicle stores this information continu-
ously in the ignition key while the vehicle is
being driven. After accessing the data stored in
the vehicle key, your BMW Service Advisor can
suggest precisely the right array of service pro-
cedures for your own individual vehicle. This is
why it is important when you take your vehicle in
for service to give the BMW Service Advisor the
last remote control you used for driving.
Storage periods with the battery discon-
nected are not taken into account by the
CBS maintenance system. Have the time-
dependent service and maintenance opera-
tions, such as brake fluid and coolant, and if
necessary engine oil and the micro/activated
charcoal filter, updated by a BMW center.<
Service and Warranty Information
Booklet for US models and
Warranty and Service Guide Booklet
for Canadian models
Please consult your Service and Warranty Infor-
mation Booklet for US models and Warranty
and Service Guide Booklet for Canadian models
for additional information on service require-
ments.
BMW recommends that you have service
and repair operations performed at your
BMW center.
Take the time to ensure that these service pro-
cedures are confirmed by entries in your vehi-
cle's Service and Warranty Information Booklet
for US models and Warranty and Service Guide
Booklet for Canadian models. These entries
verify that your vehicle has received the speci-
fied regular maintenance.<

Socket for OBD Onboard
Diagnostics
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located to the left on the driver's
side, on the underside of the instrument panel
under a cover.
Emissions values
The warning lamp lights up. The emis-
sions values are deteriorating. Have the
vehicle checked as soon as possible.
Display of the previously described
malfunction on Canadian models.
Under certain circumstances, the warning lamp
will flash. This is a sign of excessive misfiring of
the engine. In this case you should reduce
speed and drive to the nearest BMW center as
soon as possible. Serious engine misfiring,
even for only a short period of time, can seri-
ously damage emission control components,
especially the catalytic converter.
If the fuel filler cap is not properly tight-
ened, the OBD system can detect the
vapor leak and the indicator lamp will light up. If
the cap is then tightened, the display must go
out within a few days.<
Event Data Recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with a
device for recording or transmitting certain
vehicle data or information. If you have also
signed a contract of participation for BMW
Assist, certain vehicle data can be transmitted
or recorded to enable corresponding services.
Care
You can find useful information on caring for
your BMW in the Caring for your vehicle bro-
chure.

After mounting
1.Tighten the lug bolts in a diagonal pattern.
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 speci-
fied torque. The tightening torque is
100lbft/140Nm.<
2.Reverse the removal sequence when stor-
ing the wheel and tools in the vehicle.
3.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems and valve stem
seal caps from dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor, refer to
page90, or reset the Tire Pressure Monitor,
refer to page92.
5.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with spare tire
On certain wheel-tire combinations, the
size of the spare tire differs from that of
the rest of the tires. The spare tire is fully capa-
ble of running in all load and speed ranges.
However, to recreate the original conditions,
the tire should be replaced as soon as possi-
ble.<
Vehicle battery
Maintenance
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW center will be happy to advise
you on all questions concerning the battery.
Charging battery
Charge the battery in the vehicle only via the
terminals in the engine compartment and with
the engine off. Connections, refer to Jump
starting on page213.
Battery switch
Before storing the vehicle for an extended
period of several weeks or more, slide the bat-
tery switch located behind the trim panel on the
right side of the luggage compartment to OFF.
This reduces the current flow from the battery
for the period during which the vehicle remains
parked. A message is shown on the Info Dis-
play. Please take note of the supplementary
information provided on the Control Display.
Disposal
Have old batteries disposed of following
replacement at your BMW center or bring
them to a collection point. Maintain the battery
in an upright position for transport and storage.
Always secure the battery to prevent it from tip-
ping over during transport.<
Power failure
After a temporary interruption in electrical
power, the functioning of some equipment may
be limited and must be reinitialized. Individual
settings are also lost and must be updated
again:
>Seat, mirror, and steering wheel memory
The positions must be stored again, refer to
page46.
>Time and date
These must be reset, refer to page84.
>Radio
Stations must be stored again, refer to
page158.
>Navigation system
You must wait until it becomes operational
again, refer to Inserting navigation CDs/
DVDs on page130.
