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 different periods of time.
If a malfunction occurs in one of the monitored
systems, the corresponding light does not go
out after the engine has started, or it lights up
again while the vehicle is in motion. You can find
more information about each system on the
specified pages.

Odometer
With the ignition key in position 0, you can acti-
vate the displays shown in the illustration by
pressing the button – see arrow – in the instru-
ment cluster.
Trip odometer
To set to zero
Ignition key position 1
Keep the button pressed until the trip odometer
counter is set to zero.
Tachometer
Never allow the engine to operate with the nee-
dle in the red overspeed sector of the gauge.
To protect the engine, the fuel supply is inter-
rupted when you approach this sector.
Fuel gauge
When indicator lamp1 begins to stay on contin-
uously, there are still approx. 2.1 gallons/8 liters
of fuel in the fuel tank.
Tank capacity: approx. 14.5 gallons/55 liters.
If the tilt of the vehicle varies, for example when
you are driving in mountainous areas, the nee-
dle may fluctuate slightly.
Fill the fuel tank well before it is empty.
Driving to the last drop of fuel can prevent
the engine from operating properly and result in
damage.<
When you switch on the ignition, the indicator
lamp comes on briefly to indicate an operational
check.
Engine coolant temperature

The engine is still cold. Drive at moderate

Normal operating range. The needle may rise as
far as the edge of the red sector during normal
operation.
Red
When you switch on the ignition, warning
lamp1 comes on briefly to indicate an opera-
tional check.
Comes on while driving:
The engine has overheated. Stop and switch
the engine off immediately and allow it to cool
down.
For checking the coolant level, refer to page87.
Service interval display
Remaining distance to next service
The 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 INSPECTION, together with
the distance remaining in miles – in kilometers
in Canada – before the next scheduled service.
The computer bases its calculations of the
remaining distance on the preceding driving
style.
A flashing message and a minus sign 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.
Outside temperature
If the vehicle is not equipped with a computer,
the display in the instrument cluster always
shows the outside temperature.
Clock
If you wish to have a permanent time display,
you can have it appear in the car radio display,
refer to the Owner's Manual for Radio.
You can set the clock and the time display in the
car radio as follows.
To set

6.Return the dipstick to the guide tube,
inserting it as far as it will go.
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 quarts/
1 liter.
Do not fill beyond the upper mark on the
dipstick. Excess oil will damage the
engine.<
Adding engine oil
Do not add oil until the oil level has dropped
almost to the lower mark on the dipstick, refer to
page86.
Add oil within the next 30 miles/50 km,
otherwise the engine could be dam-
aged.<
Continuous exposure to used oil has
caused cancer in laboratory tests. For this
reason, thoroughly wash any areas of skin that
come into contact with oil using soap and water.
Always store oils, grease and similar materials
so that they are inaccessible to children. Com-
ply with warning labels and the information on
the containers.<
Comply with the applicable environmen-
tal laws regulating the disposal of used
oil.<
Oil change
Have your oil changed only by a BMW center or
a workshop that works according to BMW
requirements with the appropriately trained
personnel.
Approved engine oils
The quality of the engine oil is extremely impor-
tant for the function and life of an engine. Based
on extensive testing, BMW has approved cer-
tain grades of engine oil.
Use approved High Performance Synthetic Oil.
If you are unable to obtain an approved 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 concern-
ing the specific High Performance Syn-
thetic Oil or synthetic oils that have been
approved.<
You can also call BMW of North America toll-
free at 1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this information.
BMW engines are designed to operate
without oil additives; the use of additives
could even lead to damage in some cases.<
Coolant
Warning lamp
The warning lamp lights up:
The coolant level is too low. Top up the
coolant as soon as possible.
Do not open the cooling system when the
engine is hot. If you do, escaping coolant
can cause burns.<
Coolant consists of water and coolant additives.
Not all commercially available additives are suit-
able for your BMW. Your BMW center knows
which additives are appropriate.
Use only approved additives, as the
engine could otherwise be damaged. The
additives are hazardous to health.<
Comply with the applicable environmen-
tal laws regulating the disposal of coolant
additives.<

In the engine compartment

Checking the coolant level
1.The engine must be at ambient tempera-
ture
2.Open the cap of the expansion tank by turn-
ing it slightly counterclockwise to allow
accumulated pressure to escape, then
open completely
3.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 3/4 in/2 cm above it, that is up to the
second mark on the float. Refer also to the
schematic diagram next to the filler neck
4.Slowly add coolant, if necessary, until the
correct level is reached; do not overfill
5.Turn the cap clockwise until it is tightly
closed
6.Have the cause for the coolant loss
removed as soon as possible.
Brake system
Malfunction
Brake fluid
The warning lamp lights up although
the parking brake is not engaged:
Stop the vehicle immediately.
The brake fluid level in the reservoir is too low.
At the same time, you may notice that brake
pedal travel is longer. Have the system checked
as soon as possible.
If you continue driving, extended pedal
travel may be necessary and braking dis-
tances may be significantly longer. Be sure to
adapt your driving style accordingly. function in Canadian models.
Brake pads
The warning lamp lights up. The brake
pads have worn down to the minimum
safe limit. Have the brake pads
replaced as soon as possible.
For your own safety: use only brake pads
which BMW has approved for your spe-
cific vehicle model. BMW cannot evaluate non-
approved brake pads to determine if they are
suitable for use, and therefore cannot guaran-
tee the operating safety of the vehicle in the
event of their use.<
