The individual vehicle
When you ordered your BMW, you chose vari-
ous items of equipment. This Owner's Manual
describes the entire array of options and equip-
ment available with a specific BMW model.
Please bear in mind that the manual may con-
tain information on accessories and equipment
that you have not specified for your own vehicle.
Sections describing options and special equip-
ment are marked by asterisks
* to assist you in
identifying possible differences between the
descriptions in this manual and your own vehi-
cle's equipment.
If equipment in your BMW is not described in
this Owner's Manual, please refer to the accom-
panying Supplementary Owner's Manuals.
Editorial notice
BMW pursues a policy of continuous, ongoing
development that is conceived to ensure that
our vehicles continue to embody the highest
quality and safety standards combined with
advanced, state-of-the-art technology. For this
reason, it is possible in exceptional cases that
features described in this Owner's Manual
could differ from those on your vehicle.
For your own safety
Maintenance and repair
Advanced technology, e.g. the use of
modern materials and powerful electron-
ics, requires specially adapted maintenance
and repair methods. You should therefore have
the corresponding work on your vehicle per-
formed only by your BMW center or at a work-
shop that works according to BMW repair pro-
cedures with correspondingly trained
personnel. If this work is not carried out prop-
erly, there is a danger of subsequent damage
and related safety hazards.<
Parts and accessories
For your own safety, use genuine parts
and accessories approved by BMW.
When you purchase accessories tested and
approved by BMW and Original BMW Parts, you
simultaneously acquire the assurance that they
have been thoroughly tested by BMW to ensure
optimum performance when installed on your
vehicle.
BMW warrants these parts to be free from
defects in material and workmanship.
BMW will not accept any liability for damage
resulting from installation of parts and accesso-
ries not approved by BMW.
BMW cannot test every product made by other
manufacturers to verify if it can be used on a
BMW safely and without risk to either the vehi-
cle, its operation, or its occupants.
Original BMW Parts, BMW Accessories and
other products approved by BMW, together
with professional advice on using these items,
are available from all BMW centers.
Installation and operation of accessories not
approved by BMW, such as alarms, radios,
amplifiers, radar detectors, wheels, suspension
components, brake dust shields, telephones,
including operation of any mobile phone from
within the vehicle without using an externally
mounted antenna, or transceiver equipment, for
instance, CBs, walkie-talkies, ham radio or sim-
ilar accessories, may cause extensive damage
to the vehicle, compromise its safety, interfere
with the vehicle's electrical system or affect the
validity of the BMW Limited Warranty. See your
BMW center for additional information.<
Maintenance, replacement, or repair of
the emission control devices and sys-
tems may be performed by any automotive
repair establishment or individual using any cer-
tified automotive part.<

catalytic converter.
Do not fill the tank with E85, i.e. fuel containing
85 % ethanol, nor with FlexFuel. Otherwise, the
engine and fuel supply system will be dam-
aged.<
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:
>128i: 87
>135i: 89
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.
Do not use any gasoline below the speci-
fied minimum fuel grade. Otherwise, the
engine could be damaged.<
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 cosolvent, 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 also result in unscheduled maintenance.<

Wheels and tires

Wheels and tires
Tire inflation pressures
Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres-
sure.
Check the tire inflation pressure regularly
and correct it, if necessary: at least twice a
month and before starting long trips. If you fail
to observe this precaution you may be driving
on tires with incorrect tire pressures, a condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age and the risk of an accident. Do not drive
with deflated, i.e. flat tires, except when using
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.<
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 is higher.
After correcting the tire inflation pressure,
reset the Tire Pressure Monitor, refer to
page68, or reinitialize the Flat Tire Monitor,
refer to page66.<
Inflation 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 approved and tire brands recom-
mended by BMW; a list of these is available
from your BMW center.<
For correct identification of the right tire infla-
tion pressures, observe the following:>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving up to
100 mph or 160 km/h
For normal driving up to 100 mph or 160 km/h
and to achieve optimum driving comfort, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds up to a maximum of
100mph or 160km/h.
These tire inflation pressures can also be found
on the driver's side door post when the driver's
door is open.
The maximum permissible speed for
these tire pressures is 100 mph or
160 km/h. Do not exceed this speed; otherwise,
tire damage and accidents could occur.<
Tire inflation pressures for driving
above 100 mph or 160 km/h
In order to drive at maximum speeds in
excess of 100 mph or 160 km/h, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds including those
exceeding 100 mph or 160 km/h. Otherwise,
tire damage and accidents could occur.<
Observe all national and local maximum speed
limits; otherwise, violations of the laws could
occur.

Maintenance
BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The objective is to optimize
efforts with respect to minimal vehicle mainte-
nance costs.
If and when you come to sell your BMW, a com-
prehensive record of servicing will prove a sig-
nificant benefit.
Condition Based Service CBS
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
In the instrument cluster, you can have the
remaining times or distances for selected main-
tenance tasks and any legally prescribed dates
displayed, refer to page61:
>Engine oil
>Brake pads: separately for front and rear
>Brake fluid
>Vehicle check
>Legally mandated inspections depending
on local regulations
Service data in the remote control
Your vehicle continuously stores service-
requirement information in the remote control
while you are driving. Your BMW Service Advi-
sor can read out this data from the remote con-
trol unit, and propose an optimized mainte-
nance approach. Whenever you take your car in
for servicing you should therefore hand your
BMW Service Advisor the remote control unit
that you last used.
Make sure that the date in the instrument
cluster is always set correctly, refer to
page62; otherwise, the effectiveness of Condi-
tion Based Service CBS is not assured.<
