For your own safety 
Fuels
Use unleaded gasoline only. 
Fuels containing up to and including 
10 % ethanol or other oxygenates with 
up to 2.8 % oxygen by weight – that is, 
15 % MTBE or 3 % methanol plus an equiv-
alent amount of co-solvent – will not void 
the applicable warranties with respect to 
defects in materials or workmanship. Field 
experience has indicated significant differ-
ences in fuel quality – volatility, composi-
tion, additives, etc. – among gasolines 
offered for sale in the United States and 
Canada. The use of poor-quality fuels may 
result in drivability, starting and stalling 
problems, especially under certain environ-
mental conditions 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. 
Failure to comply with these recommenda-
tions may result in unscheduled mainte-
nance. 
Follow the relevant safety rules when you 
are handling gasoline.< 
Maintenance and repair
Advanced technology, e. g. the use of 
modern materials and high-perfor-
mance electronics, requires specially 
adapted maintenance and repair methods. 
Therefore, only have corresponding work 
on your BMW carried out by a BMW center 
or a workshop that works according to 
BMW repair procedures with correspond-
ingly trained personnel. If work is carried 
out improperly there is a danger of conse-
quential damage and the related safety 
risks.< 
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 Genuine BMW 
Parts, you simultaneously acquire the 
assurance that they have been thoroughly 
tested by BMW to ensure optimum perfor-
mance 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 dam-
age resulting from installation of parts and 
accessories 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 vehicle, its operation, or its occu-
pants. 
Genuine 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 non-BMW 
approved accessories such as alarms, 
radios, amplifiers, radar detectors, wheels, 
suspension components, brake dust 
shields, telephones – including operation of 
any portable phone from within the vehicle 
without using an externally mounted 
antenna – or transceiver equipment, for 
instance, CBs, walkie-talkie, ham radio or 
similar 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. Refer to your BMW cen-
ter for additional information.<
Maintenance, replacement, or repair 
of the emission control devices and 
systems may be performed by any automo-
tive repair establishment or individual using 
any certified automotive part.<  

A congenial climate
92 climate control is optimized for driving with 
the convertible top open. In addition, the air 
supply is increased as the speed increases.
If the convertible program has been 
selected, it is automatically active every 
time the top is opened.
The effect of the convertible program 
can be greatly enhanced if the wind 
deflector is fitted.<
Ventilation 
You can use the serrated dials 1 to open 
and close the vent outlets through an infi-
nitely-variable range, while the levers 2 
allow you to adjust the airflow direction.
Do not drop any foreign bodies into 
the vent outlets, as otherwise these 
could be catapulted outwards and lead to 
injuries.<
Ventilation for cooling 
Adjust the vent outlets to direct the flow of 
cool air in your direction, for instance, if the 
interior has become too warm, etc.
Draft-free ventilation 
Set the vent outlets so that the air flows 
past you and is not directed straight at you.
Microfilter/activated-charcoal filter 
The microfilter removes dust and pollen 
from the incoming air. The activated-char-
coal filter provides additional protection by 
filtering gaseous pollutants from the out-
side air. Your BMW center replaces this 
combined filter as a standard part of your 
scheduled maintenance.You can select a display of more detailed 
information in the service requirement dis-
play, refer to page 65.
Independent ventilation 
The independent ventilation blows air into 
the passenger compartment to lower inte-
rior temperatures.
The independent ventilation is controlled 
using the Control Center. You can set two 
different times for the system to start.
The independent ventilation remains on for 
30 minutes. It can also be switched on and 
off directly. Since the system uses a sub-
stantial amount of electrical current, you 
should refrain from activating it twice in 
succession without allowing the battery to 
be recharged in normal operation between 
use.
The independent ventilation is ready for 
use at any outside temperature up to igni-
tion key position 1.
The air emerges through the upper body 
region vent outlets in the instrument panel. 
These vent outlets must be open for the 
system to operate.
Switching on and off directly 
Control Center, for principle details, refer to 
page 16:
1.Open "Climate"
2.Select "Ventilation" and press the con-
troller
3.Select "Automatic ventilation" and 
press the controller
4.Select "Parked car ventilation" and 
press the controller.

Maintenance 
The BMW maintenance 
system 
The BMW maintenance system supports 
the preservation of the traffic and operating 
safety of your BMW. The service schedule 
also includes operations related to the 
vehicle's comfort and convenience fea-
tures, such as replacement of the filters for 
the inside air. The ultimate objective is to 
ensure economical maintenance by provid-
ing the ideal service for your 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 inesti-
mable value.
CBS Condition Based Service 
Sensors and special algorithms take the 
different driving conditions of your BMW 
into account. Condition Based Service 
uses this to determine the current and 
future maintenance requirement. By letting 
you define a service and maintenance reg-
imen that reflects your own individual 
requirements, the system builds the basis 
for trouble-free driving.
The service requirement display, refer to 
page 65, individually displays the time or 
distance remaining for selected mainte-
nance work and any legally required inter-
vals:
>Engine oil
>Brakes, front and rear separately
>Microfilter/activated-charcoal filter>Brake fluid
>Spark plugs
>Vehicle check
>Legally required tests depending on 
local regulations.
Your vehicle stores this information contin-
uously in the master key while the vehicle is 
being driven. After accessing the data 
stored in the master key, your BMW Ser-
vice Advisor can suggest precisely the right 
array of service procedures for your own 
individual vehicle. You should therefore 
hand over to the BMW Service Advisor the 
key you last used to drive when you take 
your vehicle for service.
Make sure the date in the Control 
Center is always set correctly, refer to 
page 74, as otherwise the effectiveness of 
CBS Condition Based Service is not 
ensured.<

Booklet for US models and Warranty 
and Service Guide Booklet for 
Canadian models 
Please consult your Service and Warranty 
Information Booklet for US models and 
Warranty and Service Guide Booklet for 
Canadian models for additional information 
on service requirements.
Have service and repair operations 
performed at your BMW center.
Take the time to ensure that these service 
procedures are confirmed by entries in 
your vehicle's Service and Warranty Infor-
mation Booklet for US models and War-
ranty and Service Guide Booklet for Cana-
dian models. These entries verify that your 
vehicle has received the specified regular 
maintenance, and may also be required 
when submitting warranty claims.<
