Coolant temperature
A warning lamp will come on if the coolant, and
therefore the engine, becomes too hot.
In addition, a message will appear on the Con-
trol Display.
Check coolant level, refer to page206.
Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 2107/1006 and approx. 3007/
1506.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 14 US gallons/
53 liters.
You can find information on refueling on
page192.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Fuel display 135i: in speedometer.
Reserve
Once the fuel level has fallen to the reserve
zone, a message briefly appears on the Control
Display and the remaining cruising range is dis-
played on the computer. Under a cruising range
of approx. 30 miles/50 km, the message
appears continuously in the Control Display.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur.<

Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking oil level
Your car is equipped with an electronic oil-level
monitor.
For precise measurement and display of the oil
level, the engine must be at operating tempera-
ture, i.e. following at least 6.2 miles/10 km of
uninterrupted driving. 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.
Display in the instrument cluster
1.Push button1 in the turn indicator lever up
or down repeatedly until the appropriate
symbol is shown in the display, accompa-
nied by the word "OIL".
2.Press button2.
The oil level is checked and the reading dis-
played.

Have the vehicle checked immedi-
ately; otherwise, the excess oil may
lead to engine damage.<
>"Measurement inactive. Have this
checked.":
Do not add engine oil. Before continuing to
drive, note the recalculated remaining mile-
age until the next oil change service, refer to
Service requirements on page72. Have the
system checked as soon as possible.
Adding engine oil
Do not add 1 US quart/1 liter of engine oil
until a corresponding message is shown
on the Control Display. Add oil within the next
125 miles/200 km; otherwise, the engine could
be damaged.<
Keep oils, greases, etc. out of the reach of
children and comply with the relevant
warnings on the containers. Otherwise, health
hazards may result.<
Oil change
Have oil changed only at your BMW center or at
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel.
Oil grades
Do not use any oil additives; otherwise,
you may cause engine damage.<
Approved engine oils
You BMW center will be happy to advise you
about the engine oils approved by the manufac-
turer of your vehicle.
The engine oil grade is a decisive factor for the
service life of the engine.
Approved engine oils can be found in the fol-
lowing specification:
Approved engine oils belong to the viscosity
classes SAE 0W-40, SAE 0W-30, SAE 5W-40,
and SAE 5W-30.
Alternative oil grades
If approved oils are not available, you can use
quantities of up to 1 US quart/1 liter of another
oil with the following specifications:
API SM or higher
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant consists of half water and half additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives; otherwise,
engine damage may result. Because
additives are harmful to your health, it is impor-
tant to follow the instructions on the contain-
ers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Gasoline engine
Preferred: BMW Longlife-01
BMW Longlife-01 FE
Alternative: BMW Longlife-98

Checking coolant level
1.Do not open the engine hood before the
engine has cooled down.
2.Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
pressure to escape, then continue turning
to open.
3.The coolant level is correct if it is between
the maximum and minimum marks in the
filler neck, refer also to the diagram next to
the filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5.Turn the cap until there is an audible click.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.
