Hood
Do not work on the car unless you pos-
sess the necessary technical knowledge.
If you are not familiar with the regulations to be
followed, have the necessary work on the vehi-
cle carried out only by your BMW center; if this
work is not carried out properly, there is a dan-
ger of subsequent dama ge and related safety
hazards. <
Releasing

Opening
In order to avoid damage, make sure that
the wiper arms are against the windshield
before you open the hood. Do not open the
engine hood before the engine has cooled
down; otherwise, injuries may result. <
Press the release handle and open the hood.
Closing
Let the hood drop from a height of approx. 10 in/
25 cm. It must be clearly heard to engage. Make sure that the closing path of the
hood is clear; othe rwise, injuries may
result.
If you see any signs while driving your vehicle
that the hood is not comp letely closed, stop at
once and close it securely. <
Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking oil level
Your car is equipped with an electronic oil-level
monitor.
For a precise measurement and display of the
oil level, it is necessar y that the engine be at
operating temperature, i.e. after uninterrupted
driving for at least approx. 6.2 miles/10 km. You
can have the oil level displayed while you are
driving, or while the vehicle is at a standstill on a
level surface and the engine is running.
You can have the oil leve l reading displayed in
the instrument cluster.

engine damage may result. Because
additives are harmful to your health, it is impor-
tant to follow the instructions on the contain-
ers. <
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives. <

optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehi cle, for example due to
the special options or national-market version

functions and systems.
BMW Maintenance System
The BMW maintenance system advises you of
necessary maintenance measures and helps
you maintain the traffic and operating safety of
the vehicle.
Condition Based Service CBS
Sensors and special algo rithms 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 requirem ents, 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 le gally prescribed dates
displayed, refer to page 84: >
Engine oil
> Brake pads: separately for front and rear
> Brake fluid
> Vehicle check
> Legally mandated in spections 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 dealership Service
Advisor can read out this data from the remote
control unit, and propose an optimized mainte-
nance approach. Whenever you take your car in
for servicing you should therefore give your
dealership Service Advisor the remote control
unit that you last used.
Make sure that the date in the instrument
cluster is always se t correctly, refer to
page 86; otherwise, the effectiveness of Condi-
tion Based Service CBS is not assured. <

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. <

Diagnosis OBD
On the drive r's side is a n OBD so cket f or check-
ing components relevant to the composition of
the vehicle's emissions.
Emissions
The warning lamp lights up:
The vehicle is producing higher emis-
sions. The trip can be continued. Have
the car checked as soon as possible.
Canadian models display this warning
lamp.
The lamp flashes under ce rtain conditions. This
indicates excessive misfiring in the engine. If
this happens, you should reduce your speed
and visit your nearest BMW center as soon as
possible. Severe engine misfiring can quickly
lead to serious damage of emissions-related
components, especially the catalytic converter.
The warning lamp lights up if the fuel
cap is not properly tightened and the
OBD system assumes that fuel vapor
is escaping. Make sure that the fuel cap is cor-
rectly positioned and close it until it audibly
clicks.
Data memory
Your vehicle records data about the operation,
faults, and user settings. These data are stored
in the vehicle and in extr act form, in the remote
control, and can be read out using suitable
devices at your BMW center. The data that are
read out are used to support service proce-
dures and repairs or to optimize and expand
vehicle functions. If you have a BMW Assist
contract, certain vehicle data can also be trans-
mitted directly from the vehicle in order to
enable the desired services.
