Indicator and warning lamps 
 
Technology that monitors itself 
 
Indicator and warning lamps that are 
identified by 
 
l
 
 are tested for proper 
functioning whenever the ignition key is 
turned. They each light up once for 
different 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 to this in the 
following section.
 
Red: stop immediately
 
Battery charge current
 
 
 
l
 
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 
serious engine damage. If the drive belt 
is defective, increased steering effort is 
also required.

Engine oil pressure
 
  
l
 
Stop the vehicle immediately 
and switch off the engine. 
Check the engine oil level and top off as 
required. If the oil level is correct, 
please contact the nearest BMW 
center.
Do not continue driving, as the 
engine could sustain serious 
damage from inadequate lubrication.

If the lamp comes on when the 
parking brake is not engaged: 
check the brake fluid level. Before 
driving further, be sure to comply with 
the instructions on pages 106 and 118

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 and avoid overcorrecting.

Indicator lamp flashes: 
The system is actively regulating drive 
torque and braking force. 
The indicator lamp stays lit:
ASC+T has been switched off with the

DSC has been switched off manually or 
there is a system malfunction. ADB-X is 
operational in its standby mode. If the 
warning lamp fails to go out when you 
press the DSC button again, this indi-
cates a system malfunction affecting 
both DSC and ADB-X.
Please consult the nearest BMW

Fuel gauge  Temperature gauge  Service Interval DisplayOnce the indicator lamp stays on 
continuously, there are still approx. 
2 gallons (8 liters) of fuel in the fuel 
tank.
For fuel tank capacity, refer to 
page 143.
Certain operating conditions (such as 
those encountered in mountainous 
areas) may cause the needle to fluc-
tuate 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 an 
operation 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 during normal 
vehicle operation: the engine has over-
heated. Switch off the engine immedi-
ately and allow it to cool down.
Checking coolant level, refer to 
page 117.Between the blue and red zonesNormal operating temperature. The 
needle may rise as far as the edge of 
the red sector in normal operation.
Remaining distance to 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 OIL SERVICE or INSPEC-
TION, together with the distance 
remaining in miles (kilometers) 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.

Engine oilChecking 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 
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. 
1.1 US quarts (1 liter). Do not fill beyond 
the upper mark on the dipstick. Excess 
oil will damage the engine.
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 is also true for the 
manual transmission, the automatic 
transmission, the differential, and the 
power steering system.<
Recommendation: have the oil changed 
by your BMW center.

Engine oil
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 
warning labels and information on 
containers.<
Comply with the applicable envi-
ronmental laws regulating the 
disposal of used oil.<
Specified engine oilsThe quality of the engine oil is 
extremely important for the function 
and service life of an engine. Based on 
extensive testing, BMW has approved 
only certain grades of engine oil. 
Use only approved "BMW High 
Performance Synthetic Oil". 
If you are unable to obtain an approved 
"BMW High Performance Synthetic 
Oil", you may use small volumes of 
other synthetic oils for topping up 
between oil changes. Use only oils with 
the specification API SH or higher. 
Ask your BMW center for details 
concerning the specific "BMW 
High Performance Synthetic Oil" or 
synthetic oils that have been 
approved.<
You can also call BMW of North 
America at 1-800-831-1117 or visit this 
website: www.bmwusa.com to obtain 
this information.
Viscosity ratings Viscosity 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 you drive your BMW.
Approved oils are in SAE classes 
5W-40 and 5W-30.<
These kinds of oil may be used for 
driving in all ambient temperatures.

OverviewControlsMaintenanceRepairsDataIndex
The BMW Maintenance System has 
been designed as a reliable means of 
providing maximum driving and oper-
ating safety Ð and as cost-effectively as 
possible for you.
Please keep in mind that regular main-
tenance is not only necessary for the 
safety of your vehicle, but also plays a 
significant role in maintaining the resale 
value of the vehicle.
Service Interval DisplayWhile conventional systems rely on 
distance traveled alone to determine 
when service is due, the BMW Mainte-
nance System has for years considered 
the actual conditions under which the 
vehicle operates, because miles can be 
traveled in many different ways:
From a maintenance point of view, 
62,000 miles (100,000 km) of short-
distance urban driving cannot be 
compared with 62,000 miles 
(100,000km) of long-distance highway 
travel.
The BMW Maintenance System 
includes the Engine Oil Service and 
Inspections I and II.
Determining the maintenance intervals 
according to the actual use of the 
vehicle covers every kind of operating 
situation. However, drivers who cover 
only extremely short distances Ð 
substantially less than 6,200 miles 
(10,000 km) annually Ð should still have 
the engine oil changed at least every 
2 years, as it continues to age regard-
less of whether the vehicle is used on a 
regular basis.
Service and Warranty Information 
Booklet (US models)/Warranty 
and Service Guide Booklet (Cana-
dian models)For additional information on required 
maintenance intervals and procedures, 
please refer to the Service and 
Warranty Information Booklet (US 
models), or the Warranty and Service 
Guide Booklet (Canadian models).
As a precaution against corrosion, it is 
advisable to have the body checked for 
damage from rocks or gravel at the 
same time, depending upon operating 
conditions.
We recommend that you refer all 
maintenance and repair opera-
tions to your BMW center.
Be sure that all maintenance work is 
confirmed in the Service and Warranty 
Information Booklet (US models), or in 
the Warranty and Service Guide 
Booklet (Canadian models). These 
entries confirm that your vehicle has 
benefitted from regular maintenance, 
and are also required for warranty 
claims.<
