Minimum fuel grade
BMW recommends AKI 89.
Do not use gasoline below the indicated
minimum fuel grade; otherwise, proper
engine function is not ensured. <
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.
The use of poor-quality fuels may result in
harmful engine deposits or damage.
Additionally, problems re lating to drivability,
starting and stalling may occur, especially
under certain environmental conditions such as
high ambient temperatur e and high altitude.
If drivability problems are encountered, we rec-
ommend switching to a high quality gasoline
brand and a higher octane grade — AKI number
— for a few tank fills. To avoid harmful engine
deposits, we highly recommend purchasing
gasoline from BP or Top Tier retailers.
Failure to comply with these recommendations
may result in th e need for unscheduled mainte-
nance. <

Releasing
Pull the lever.
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; otherwise, 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
General information
The engine oil consumption is dependent on
driving style and operating conditions; for
example, the engine oil consumption is signifi-
cantly higher with a very sporty driving style.
For this reason, regularly check the oil level
after each time you refuel.
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.
Display in the instrument cluster
1.Push button 1 in the turn signal/high beam
lever up or down repe atedly until the appro-
priate symbol is shown in the display,
accompanied by the word "OIL".
2. Press button 2 in the turn signal/high beam
lever.
The oil level is chec ked and the reading
displayed.

Coolant
Coolant consists of half water and half additive.
Not all commercially availa
ble additives are suit-
able for your BMW. Ask your BMW center about
suitable additives.
Only use suitable a dditives; otherwise,
engine damage may result. Because
additives are harmful to your health, it is
important to follow the instructions on the
containers. <
Comply with the appropriate environ-
mental protection regulations when
disposing of coolant additives. <
Coolant temperature
If the coolant and therefore the engine over-
heats, a warning lamp lights up. A message
appears on the Control Display.
Checking coolant level
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns. <
1. Do not open the engine hood before the
engine has cooled down.
2. Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
pressure to escape, then continue turning
to open.
3. The level indicator 1 in the coolant filler
neck indicates the le vel of coolant. The
coolant level is correct when it is between
the arrows of the resp ective inscription on
the reservoir 2. 4.
If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5. Turn the cap until there is an audible click.
6. Have the reason for the coolant loss
eliminated as soon as possible.

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 al gorithms take the
different 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.
On the Control Display, you can have the
remaining times or distances for selected main-
tenance tasks and any legally prescribed dates
displayed, refer to page 88: >
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 is always set
correctly, refer to page 92; otherwise, the
effectiveness of Condit ion Based Service CBS
is not assured. <

Socket for Onboard
Diagnosis OBD
The socket for onboard diagnosis should
only be used by your BMW center or at a
workshop that works according to BMW repair
procedures with corres pondingly trained per-
sonnel and by otherwise authorized personnel;
otherwise, use can result in malfunctioning of
the vehicle. <
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.
