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 page227.
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. 15.9 US gallons/
60 liters.
You can find information on refueling on 
page210.
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.<

Calling up information
Press the button in the turn indicator lever.
The following items of information are dis-
played in the order listed:
>Cruising range
>Average speed
>Average fuel consumption
>Current fuel consumption
*
>No information
To set the corresponding units of measure, 
refer to Units of measure on page78.
Cruising range
Displays the estimated cruising range available 
with the remaining fuel. The range is calculated 
on the basis of the way the car has been driven 
over the last 18 miles/30 km and the amount of 
fuel currently in the tank.

>reduced efficiency of the fuel-vapor recov-
ery 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:
>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 
driveability, 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.<
