Coolant temperature
A warning lamp will come on if the coolant, and
therefore the engine, becomes too hot. In addi-
tion, a message will appear on the Control Dis-
play.
Check coolant level, refer to page218.
Energy Control*
Displays the current fuel consumption. This
allows you to see whether your current driving
style is conducive to fuel economy with mini-
mum exhaust emissions.
Engine oil temperature*
During standard operation, the engine oil tem-
perature is between approx. 1207 and approx.
3007/approx. 506 and approx. 1506. If the
engine oil temperature is too high, a message
will appear on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 15.9 US gallons/
60 liters.
You can find information on refueling on
page201.
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.
Reserve
Once the fuel level has fallen to the reserve
zone, a message briefly appears on the Control
Display and the cruising range for the remaining
amount of fuel is displayed on the computer.
Under a cruising range of approx. 30 miles/
50 km, the message remains in the Control Dis-
play.
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.<

Observe the following when refueling
When handling fuels always observe any
safety guidelines posted at the service
station.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid lifting the filler
nozzle while filling the tank, as that would lead
to
>premature pump shutoff
>a reduced efficiency of the fuel-vapor
recovery system.
The fuel tank is full when the filler nozzle clicks
off the first time.
Fuel tank capacity
Approx. 16.1 US gallons/61 liters, including the
reserve capacity of 2.1 US gallons/8 liters.
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.<
Fuel specifications
Do not fill the tank with leaded fuel, as this
would cause permanent damage to the
catalytic converter.
Do not fill the tank with E85, i.e. fuel containing
85 % ethanol, nor with FlexFuel. Otherwise the
engine and fuel supply system will be dam-
aged.<
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:
>323i, 328i/xi: 87
>335i: 89.
If you use gasoline with this minimum AKI Rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.Do not use any gasoline below the speci-
fied minimum fuel grade. Otherwise the
engine could be damaged.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10 % ethanol or other
oxygenates with up to 2.8 % oxygen by weight,
that is, 15 % MTBE or 3 % methanol plus an
equivalent amount of co-solvent, will not void
the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
drivability, starting and stalling problems
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter driveability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<
