Engine oil temperature gauge
The general operating temperature lies 
between 1757/806 and 2507/1206. Do 
not exceed a value of approx. 2657/1306.
If the engine oil temperature is too high, the per-
missible engine speed, and with it the available 
engine output is reduced.
Fuel gauge
Fuel tank capacity: approx. 18.5 US gal/
70 liters. You can find information on refueling 
on page194.
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
After the reserve quantity has been reached, a 
message briefly appears on the Control Display; 
the cruising range is shown in the computer. 
Below a range of approx. 30 miles/50 km, the 
message remains on 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.<
Computer
Displays in instrument cluster
To display the information, press the BC button 
in the turn signal lever.
The following information is displayed in the 
specified order:
>Time and outside temperature
>Cruising range
>Average fuel consumption
>Oil level, refer to Checking engine oil level 
on page203
Manual transmission:
The range, average consumption and 
fluid level are shown in the lower display in place 
of the gear indicator.
It is possible to change between the time and 
date display by pressing the CHECK button.<
Time
To set the time, refer to page76.
Outside temperature warning
If the display drops to +377/+36, a signal 
sounds and a warning lamp lights up. A mes-
sage appears on the Control Display. There is 
an increased danger of ice.
Ice can form even at temperatures above 
+377/+36. Drive carefully, especially 
on bridges and shaded roadways; otherwise, 
your risk of accident increases.<
You can set the unit of measure 7 or 6 on the 
Control Display, refer to Units of measure on 
page78. 

Under the hood
204 After starting the engine, the last determined 
value is displayed.
The oil level must be between the two marks.
Manual transmission: the fluid level will be 
shown in the lower display.<
Exact measurement
The oil level is measured continuously while 
driving or when stopped with the engine run-
ning.
The determination of a new value can take 
30 minutes or longer.
If only dashes are shown in the display, 
it was not possible to determine a new 
value. This can, for example, be the case when 
driving short distances or with a sporty driving 
style.<
Fast measurement
In addition to the continuous measurement, you 
can also quickly determine the current oil level, 
e.g. after adding engine oil, however with a low 
measuring accuracy.
1.With the engine at operating temperature, 
i.e. after at least 6 miles/10 km of uninter-
rupted driving, park the vehicle in a horizon-
tal position.
2.Allow the engine to run at idle.
3.Press the BC button in the turn signal lever 
repeatedly until the oil level display is 
shown in the instrument cluster.
4.Press the BC button in the turn signal lever 
for at least 2 seconds.
The oil level is determined. A clock symbol 
is displayed during the measurement.
5.After approx. 1 minute the current oil level is 
displayed.
If not all measuring conditions are met, 
e.g. with the engine cold, "-.-" is dis-
played. The requested measurement is carried 
out as soon as possible.<
Possible displays
1Oil level OK
2Oil level at minimum:
Add a maximum of 1 US quart/1 liter of 
engine oil at the next opportunity, refer to 
Adding engine oil below
3Oil level is too high
Have the vehicle checked immedi-
ately; otherwise, engine damage may 
result if too much oil has been added.<
4Oil level at maximum
5Fast measurement running: oil level is being 
determined
6No value can be determined at this time
Adding engine oil
Do not add oil until a value slightly above the 
minimum of 0.0 US quarts/liters is displayed by 
the oil level measurement. In this area a mes-
sage is also shown on the Control Display.
Add oil within the next 125 miles/200 km, 
otherwise the engine could be damaged.
Add a maximum of 1 US quart/1 liter of oil, oth-
erwise the engine may be damaged by adding 
too much oil.
