Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by

●

are tested for proper
functioning whenever the ignition key is
turned. They each light up once for dif-
ferent periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started, or
it lights up while the vehicle is moving.
You will see how to react in the follow-
ing section.

Red: stop immediately

Battery charge current

●

The battery is no longer being
charged. Indicates a defective
alternator drive belt or a problem with
the alternator's charge circuit. Please
contact the nearest BMW center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and seri-
ous engine damage. If the drive belt is
defective, increased steering effort is
also required.

<

Engine oil pressure

●

Stop the vehicle immediately
and switch off the engine.
Check the engine oil level; top off as
required. If the oil level is correct:
please contact the nearest BMW cen-
ter.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

In addition, an acoustic signal is
sounded: a tire failure has occurred.
Reduce vehicle speed immediately and
stop the vehicle. Avoid hard brake
applications. As you steer the vehicle,
use caution to avoid overcorrecting.

Service interval displayRemaining distance to next
serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or higher or
after the engine is started.
The next service due appears with the
message OIL SERVICE or
INSPECTION, together with the dis-
tance remaining in miles – in kilometers
in Canada – before the next scheduled
service.
The computer bases its calculations of
the remaining distance on the preced-
ing driving style.
A flashing message and a "–" in front of
the number mean that the service inter-
val has already been exceeded by the
distance shown on the display. Please
contact your BMW center for an
appointment.
Check ControlDisplayWhen the ignition key is in position 2 or
higher, the following information and/or
conditions are indicated using symbols
until the condition has been corrected.
1Check the low and high beams as
well as the parking lamps
2Door open
3Luggage compartment lid open
4Check tail or brake lamps
When you open the driver's door after
parking, a signal sounds to remind you
if the headlamps have not been
switched off.

Wheel and tire combinationsThe right choice
BMW recommends using only
wheels and tires that have been
approved by BMW for your particular
vehicle model, as otherwise body con-
tact and serious accidents can result
despite the use of the same nominal
size, e.g. due to manufacturing toler-
ances. BMW cannot evaluate all tires
and wheels on the market, and is thus
unable to guarantee that the vehicle will
continue to perform safely if unap-
proved tires and/or wheels are
mounted.<
For each tire size, BMW has assessed
the safe performance of specific tire
brands and approved them for use.
Consult any BMW center for details.
Comply with any local/national regula-
tions, for example by recording the tire
type in the vehicle documents.
The correct wheel and tire combi-
nation affects various systems
that would otherwise be impaired, for
example ABS, ASC+T/DSC and
ADB/DBC.
For this reason, use only tires of the
same manufacture and tread configura-
tion. In the event of a flat tire, for exam-
ple, remount the approved wheel and
tire combination as soon as possible.<
StorageStore tires in a cool, dry place, protect-
ing them against light whenever possi-
ble. Protect the tires against contact
with oil, grease and fuel.
Winter tiresChoosing the right tireBMW recommends winter tires – M+S
tires – for operation under inclement
winter driving conditions. While all-sea-
son tires – M+S designation – provide
better winter traction than the corre-
sponding summer tires, they generally
do not achieve the performance of win-
ter tires.
In the interest of safe tracking and
steering response, install winter tires
made by the same manufacturer and
with the same tread configuration on all
four wheels.
Never exceed the maximum
speed for which the winter tires
are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by trained
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<

Washer fluidHeadlamp* and windshield
washer systemApproximate capacity is
5.6 US quarts/5.3 liters.
Fill with water and – if required – with a
washer antifreeze additive according to
manufacturer's recommendations.
We recommend that you mix the
washer fluid before adding it to
the reservoir.<
Antifreeze agents for the washer
fluid are highly flammable. For this
reason, keep them away from sources
of flame and store them only in original
containers, inaccessible to children.
Comply with the instructions on the
containers.<
Engine oilChecking the oil level1. Park the vehicle on a level surface
2. Switch the engine off after it has
reached normal operating tempera-
ture
3. After approx. 5 minutes, pull the dip-
stick 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.
1.1 US quarts/1 liter. Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.
handbook.book Page 136 Wednesday, July 31, 2002 9:29 AM

137
Adding engine oilWait until the level has dropped to just
above the lower mark before adding oil.
However, you should never let the oil
drop below the lower mark.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This also applies to the
manual transmission, the automatic
transmission, the differential, and the
power steering system.<
Recommendation: have the oil changed
at your BMW center.
Continuous exposure to used oil
has caused cancer in laboratory
testing. For this reason, any skin areas
that come into contact with oil should
be thoroughly washed with soap and
water.
Always store oil, grease, etc., out of
reach of children. Comply with all warn-
ing labels and information on lubricant
containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of used oil.<
Specified engine oilsThe quality of the engine oil is
extremely important for the operation
and service life of an engine. Based on
extensive testing, BMW has approved
only certain grades of engine oil.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If an approved BMW High Performance
Synthetic Oil should be unavailable, you
may use small amounts of other syn-
thetic oils for topping up between oil
changes. Use only oils with the specifi-
cation API SH or higher.
Ask your BMW center for details
concerning the specific BMW
High Performance Synthetic Oil or syn-
thetic oils that have been approved.<
You can also call BMW of North Amer-
ica toll-free at 1-800-831-1117 or visit
this website: www.bmwusa.com to
obtain this information.
Viscosity ratingsViscosity is the oilflow rating as estab-
lished in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area where you drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These kinds of oil may be used for driv-
ing in all ambient temperatures.
