Opening and closing Ð from the inside With this button you operate the central
locking system whenever the doors are
closed. The doors and luggage
compartment lid are unlocked or locked
only. The anti-theft system is not acti-
vated.
If only the driver's door was
unlocked from the outside and
you press the button, then, with the
driver's door still open, the passenger's
door, the luggage compartment lid and
the fuel filler door will unlock, too.
If the driver's door is closed, it will be
locked.<
If you desire, the central locking
system will secure the locks as
soon as you start to drive. This can be
adjusted to be key-specific.<
To unlock and open the doors>Either unlock the doors together with
the button for the central locking
system and then pull each of the
release handles above the armrests
or
>pull the release handle for each door
twice: the first pull unlocks the door,
and the second one opens it.
To engage the locks>Either use the central locking button
to lock all doors at once
or
>press down the individual door lock
buttons. To prevent the driver from
being inadvertently locked out of the
vehicle, the driver's door lock button
will not engage as long as the door is
open.
Since passengers or animals
remaining in the vehicle might be
able to lock the doors from the inside,
take the vehicle's keys with you so that
the vehicle can be opened again from
the outside at any time.<

Fuel gauge Temperature gauge Service Interval Display Once the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel in the fuel
tank.
Fuel tank capacity: approx. 16.6 gal.
(63 liters).
If the tilt of the vehicle varies (when you
are driving in mountainous areas, for
example), the needle may fluctuate
slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<
When you switch on the ignition, the
indicator lamp lights up briefly as a
functional check.
BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds. RedWhen you switch on the ignition, the
warning lamp comes on briefly to
confirm that the system is operational.
If the lamp comes on while operating
the vehicle, the engine has overheated.
Switch off the engine immediately and
allow it to cool down.
Checking coolant level, refer to
page 112.Between the blue and red zonesNormal operating range. The needle
may rise as far as the edge of the red
sector in normal operation.
Remaining distance for serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The next service due appears with the
message OILSERVICE or INSPECTION,
together with the distance remaining
before the next scheduled service.
The computer bases its calculations of
the remaining distance on the
preceding driving style.
A flashing message and a "Ð" in front of
the number mean that the service
interval has already been exceeded by
the distance shown on the display.
Please contact your BMW center for an
appointment.

Tire replacement Wheel and tire combinationsTire ageBMW recommends the replacement of
all tires after 6 years at the latest, even
if a tire life of 10 years is possible.
The date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 4 101 means that the tire was
produced in the 41st week of the year
2001. Following wheel/tire changesFollowing wheel and/or tire replace-
ment you will need to reinitialize both
the Flat Tire Monitor and the sequential
M gearbox
* SMG II, refer to pages 65,
78.
The right choice
Use only wheels and tires
approved by BMW for the corre-
sponding vehicle model, as otherwise
the tires may make contact with the
body as the result of tolerances despite
the same nominal size being used,
resulting in serious accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
BMW tests certain tire brands for each
tire size, classifies them as road-safe
and approves them. Consult your BMW
center for more information. Observe
any country-specific regulations, e.g.
on making a corresponding entry in the
vehicle documents.
The correct wheel and tire combi-
nation affects different systems
such as ABS, DSC, Flat Tire Monitor.
The function of these systems is
impaired if improper wheel and tire
combinations are used.
For this reason, use only tires of the
same brand and tread pattern on the
vehicle and, for example, restore the
approved wheel and tire combination
following a flat tire as soon as possible.<
The use of rims and lug bolts that
do not meet the specifications of
the original factory-installed equipment
will affect the safe operation of your
vehicle and may cause an accident and
personal injury.
Never mix tires of different design, such
as steel-belted radials with radial bias-
belted or bias-ply tires, etc. Mixing tire
types will adversely affect roadholding
and can lead to loss of vehicle
control.<
Storage Store tires in a cool, dry place,
protecting them against light whenever
possible. Protect the tires against
contact with oil, grease and fuel.

Engine oilChecking engine oil level 1. Park the vehicle on a level surface
2. With the engine warmed to its normal
operating temperature, allow it to idle
for at least 15 seconds, then switch
off
3. After approx. 1 minute, pull the
dipstick out and wipe it off with a
clean lint-free cloth, paper towel, or
similar material
4. Carefully push the dipstick all the
way into the guide tube and pull it
out again
5. The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.
The oil volume between the two marks
on the dipstick corresponds to approx.
1.4 US quarts (1.3 liter).
Adding engine oil While you should wait until the level has
dropped to just above the lower mark
before adding oil, you should never
allow the oil level to fall below this
mark.
Do not fill beyond the upper mark on
the dipstick. Excess oil will damage the
engine.
Before checking the engine oil level
after topping up, restart the engine and
allow it to run to obtain a correct
display. Then proceed as described
under "Checking engine oil level".

OBD interface socketThe Onboard Diagnostic (OBD) inter-
face socket is located on the left of the
driver's side at the bottom of the instru-
ment panel and under a cover. The
cover has the letters "OBD" on it.
The purpose of the OBD system is to
assure proper emission-control system
operation for the vehicle's lifetime by
monitoring emission-related compo-
nents and systems for deterioration and
malfunction.
An illuminated lamp informs you
of the need for service, not of
the need to stop the vehicle.
However, the systems should be
checked by your BMW center at the
earliest possible opportunity
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact your
nearest BMW center immediately.
Severe engine misfiring over even a
short period of time can seriously
damage emission-control system
components, especially the catalytic
converter.

If the fuel filler cap is not on tight
enough, the OBD system can
detect leaking vapor and the indicator
will light up. If the fuel filler cap is then
tightened, the indicator will usually go
out after a short period of time.<
