 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.

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.

Refuel Fuel specificationsSimple and environmentally 
friendly
Open the fuel filler cap carefully to 
prevent fuel from spraying out. 
Fuel spray may cause injury.<
Put the filler cap in the bracket (arrow) 
attached to the fuel filler door.
When refueling, insert the filler nozzle 
completely into the filler pipe. Pulling 
the nozzle out of the pipe during refu-
eling 
>results in premature pump shutoff
>and will reduce the effectiveness of 
the vapor recovery system on the 
pump.
As long as the filler nozzle is used prop-
erly, the fuel tank is full whenever the 
nozzle shuts off the first time.
Refill early to avoid damaging the 
catalytic converter; never attempt 
to drive to the last drop of fuel in the 
tank.<
Close the fuel filler cap carefully 
after refueling until a click is 
heard. While closing, be sure not to 
squeeze the strap which is fastened to 
the cap. A loose or missing cap will 
activate the CHECK FILLER CAP lamp 
or the SERVICE ENGINE SOON lamp.<
Tank capacity: approx. 16.6 gal. 
(63 liters), incl. a reserve capacity of 
approx. 2.1 gal. (8 liters).
The engine uses lead-free gasoline 
only.
Required fuel: 
>Premium Unleaded Gasoline, 
min. 91 AKI. 
AKI = Anti Knock Index
Never use leaded fuel, as it would 
cause permanent and irreversible 
damage to the oxygen sensor and the 
catalytic converter.<

in mpg (in liters/100 km on Canadian 
models). You can check your current 
driving style to see whether it is condu-
cive to economy and minimum exhaust 
emissions.
When the vehicle is stationary, the 
display goes to "Maximum" (zero on 
Canadian models).

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.

Tire Pressure Monitor (RDC)
*
The conceptRDC monitors the tire pressures at all 
four wheels while the vehicle is moving. 
The system provides an alert whenever 
the inflation pressure drops significantly 
below the specified pressure in one or 
more tires.
In order for the system to learn the 
correct tire inflation pressure, check the 
inflation pressure in all tires according 
to the inflation pressure table on 
page 25 and make corrections as 
necessary. Then activate the system. 
This indicator lamp in the instru-
ment cluster will inform you if 
the tire pressure is not correct.
To activate the system1. Turn ignition key to position 2 (do not 
start the engine)
2. Press the button long enough for the 
yellow indicator lamp in the instru-
ment cluster to light up for a few 
seconds
3. After a few minutes driving time, the 
RDC adopts the current pressure 
levels as the reference, and from that 
point on, can detect and report a flat 
tire.
You will only have to repeat this proce-
dure following a correction of the tire 
inflation pressure. Otherwise, RDC 
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.
In the event of loss in inflation 
pressureIf the inflation pressure has dropped 
significantly over a long period of time 
(which is normal for any tire), the yellow 
indicator lamp will come on.
This alerts you to have the tires inflated 
to the specified pressures as soon as 
possible.
If you are prompted to check the 
tire pressure shortly after a 
correction has been made, this indi-
cates that the corrected values were 
not accurate. Please check the inflation 
pressure again and make corrections 
according to the inflation pressure 
table. Then activate the system once 
again.<

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.

Coolant
Do not add coolant to the cooling 
system when the engine is hot. If 
you attempt to do so, escaping coolant 
can cause burns.
To avoid the possibility of damage later 
on, never use anything other than 
factory-approved, nitrite and amino-
free extended-duty antifreeze with 
corrosion inhibitor. Your BMW center is 
familiar with the official specifications. 
Antifreeze and anti-corrosion agents 
are hazardous to health. You should 
always store them in their original 
container and in a location which is out 
of reach of children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable 
substance ethylene glycol. For this 
reason, do not spill extended-duty anti-
freeze with corrosion inhibitor on hot 
engine parts. It could ignite and cause 
serious burns.<
Checking coolant levelCorrect coolant level when the engine 
is cold (approx. 68 7 or +20 6):
1. Open the cap for the expansion tank 
by turning it slightly counterclock-
wise to allow accumulated pressure 
to escape, then open
2. The coolant level is correct when the 
upper end of the red float is at least 
even with the upper edge of the filler 
neck, but no more than 0.8 in (2 cm) 
above it Ð that is, up to the second 
mark on the float (refer also to the 
schematic diagram next to the filler 
neck)
3. If necessary, add coolant. If the 
coolant is low, slowly add coolant 
until the correct level is reached Ð do 
not overfill.
Comply with the applicable envi-
ronmental laws regulating the 
disposal of extended-duty antifreeze 
with corrosion inhibitor.<
