Indicator and warning lamps
Technology that monitors itself
Indicator and warning lamps that are identified
by
+ are tested for proper functioning whenever
the 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 lamp 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.

Reserve
Once the fuel level has fallen to the reserve
zone of approx. 2.1 US gallons/8 liters, indicator
lamp 1 lights up continuously.
Do not drive until the fuel tank is empty
and refill it well in advance. Otherwise the
engine may not operate properly and damage
could result.<
When you switch on the ignition, the indicator
lamp comes on briefly to indicate an operational
check.
Engine coolant temperature
gauge
Blue
The engine is still cold. Drive at moderate
engine and vehicle speeds.
Between the blue and red zones
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 page94.
Service interval display
The remaining driving distance in miles/km until
the next scheduled service is displayed briefly
immediately after you start the engine or switch
on the ignition.
The words OILSERVICE or INSPECTION indi-
cate the type of service due next. The computer
bases its calculations of the remaining driving
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 number of miles/
kilometers shown on the display. Please sched-
ule an appointment with your BMW center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel.
The extent of service work required can
be read out from the remote control by
your BMW Service Advisor.<
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 time and the time display in the
car radio as follows.

Add engine oil at the earliest opportunity, e.g.
when you stop to refuel.
The warning lamp lights up in yellow
within 30 seconds after the engine is
started: the oil level sensor is defective.
It is not possible to issue a current or accurate
measurement. Have the system checked as
soon as possible.
Checking the oil level
Your car is equipped with an electronic oil-level
monitor.
For a precise measurement and display of the
oil level, it is necessary that the engine be at
operating temperature, i.e. after uninterrupted
driving for at least approx. 6.5 miles/10 km. You
can have the oil level displayed while you are
driving, or while the vehicle is at a standstill on a
level surface and the engine is running.
You can have the oil level reading displayed in
the instrument cluster.
Press button1. The oil level is checked and dis-
played for approx. 15 seconds.
To exit the display sooner, press button 1 again.
Possible displays
1Oil level OK
2Oil level is being checked.
This can take about 3 minutes if the car is at
a standstill on a level surface, or about
5 minutes while the car is on the move.
3Oil level down to minimum:
Add 1 US quart/1 liter of engine oil as soon
as possible, refer also to Adding engine oil.
4Oil level is too high.
Have the vehicle checked immedi-
ately, as excessive oil can damage the
engine.<
5The oil level sensor is defective:
it is not possible to issue a current or accu-
rate measurement.
Do not add engine oil. You can continue
your journey. Have the system checked as
soon as possible.

Adding engine oil
Do not add the maximum amount of 1 US quart/
1 liter of engine oil until the warning lamp lights
up in the instrument cluster, refer to page92, or
until the oil level monitor shows "+1.0".
Add oil within the next 125 miles/200 km,
otherwise the engine could be dam-
aged.<
Keep oils, greases, etc. out of the reach of
children and comply with the warnings on
the containers. Otherwise, health hazards may
result.<
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. BMW
continuously approves specific oils after con-
firming their suitability for use in its vehicles
with extensive testing.
Only use approved BMW High Performance
Synthetic Oil.
If BMW High Performance Synthetic Oil is not
available, you can add small quantities of other
synthetic oils in between oil changes. Only use
oils with the API SH specification or higher.
Your BMW center will be glad to answer
any questions regarding BMW High Per-
formance Synthetic Oil or other approved syn-
thetic oils. 1-800-831-1117 or visit the website
www.bmwusa.com to obtain this information.
Do not use any oil additives, as they could
cause engine damage under some cir-
cumstances.<
Viscosity classes
Viscosity is a measure of an oil's flow rating and
is categorized in SAE classes.
Selecting the appropriate SAE class depends
on the regional climatic conditions in which you
normally drive your BMW.
Approved oils belong to the 5W-40 and
5W-30 classes.<
These oils can be used for driving at all outside
temperatures.
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.
Only use approved additives, otherwise
the engine could be damaged. The addi-
tives are hazardous to health.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking the coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
