Engine oil thermometer
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 gallons/
70 liters. You will 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.
Reserve
After the reserve quantity has been reached, a
message briefly appears on the Control Display;
the remaining 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.<

Displays in instrument cluster
To display the information, press the BC button
on 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 page200
Manual transmission:
The cruising range, average fuel con-
sumption and oil level are shown in the lower
display in place of the gear indicator.
It is possible to change between the time and
data display by pressing the CHECK button.<
Time
Setting the time, refer to page74.
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.
Even at temperatures above +377/
+36 ice can form. Therefore, drive care-
fully, e.g. on bridges and sections of road in the
shade, otherwise there is an increased accident
risk.<
You can set the unit of measure 7 or 6 on the
Control Display, refer to Units of measure on
page76.

Check Control
The concept
The Check Control monitors functions in the
vehicle and issues a message if there is a mal-
function in the monitored systems. This kind of
Check Control message consists of indicator
and warning lamps in the instrument cluster,
and if necessary an acoustic signal and text
messages at the bottom of the Control Display.
Indicator and warning lamps
The indicator and warning lamps can light up in
different combinations and colors.
means that a Check Control message has
been generated. The symbol continues to be
visible even when the Check Control message
disappears after a short time. The warning
lamps and text messages are stored and can be
displayed later, also refer to page72.
Explanatory text messages
Text message at the bottom edge of the Con-
trol Display explain the meaning of the dis-
played indicator and warning lamps.

The initialization must be repeated after
each time the tire inflation pressure is cor-
rected and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natural,
even pressure drop in all four tires.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically. Do not initialize the sys-
tem when driving with snow chains.<
With Sequential Manual Transmission via the
button in the center console:
1.Start the engine, but do not start driving.
2.Press the button at least 4 seconds, how-
ever not longer than 2 minutes. After
releasing the button, the warning lamp in
the instrument cluster lights up yellow for a
few seconds. Warning lamp, refer to Indica-
tion of a flat tire. The message "Initializing
FTM ..." appears on the Control Display for
a few seconds.
3.Start to drive. The initialization finishes dur-
ing driving without feedback.Via iDrive, for explanation of principle, refer to
page16:
1.Press the button.
This opens the start menu.

Indication of a flat tire
The warning lamp lights up red. A mes-
sage appears on the Control Display.
In addition, an acoustic signal sounds.
There is a flat tire or extensive inflation pressure
loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify damaged tire. To do this, check the
tire inflation pressure using the M Mobility
System, refer to Producing tire inflation
pressure on page210.
3.Repair flat tire with M Mobility System, refer
to page208, or replace the damaged wheel,
refer to Changing wheels on page210.
TPM Tire Pressure Monitor*
The concept
TPM checks the tire inflation pressure in the
four mounted tires. The system reports when
the tire inflation pressure has dropped consid-
erably in one or several tires.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must have been reset with the
correct tire inflation pressure.
Always use wheels with TPM electronics, oth-
erwise fault-free operation of the system is not
ensured.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
System limits
TPM cannot announce sudden serious
tire damage caused by external influ-
ences.<
The system does not function properly if it has
not been reset, e.g. a flat tire is reported despite
correct tire inflation pressures.
The system is inactive and cannot display a flat
tire if a wheel has been mounted without TPM
electronics, or if TPM is temporarily interfered
with by other systems or devices which use the
same radio frequency.
Status display on Control Display
The tire and system status is indicated by the
color of the tires.
TPM takes the fact that the tire pressure
changes during driving into account. A correc-
tion is only required if requested by TPM with
the color.
Green
The tire pressure matches the learned set state.
"TPM active" is displayed on the Control Dis-
play.
One wheel is yellow
Flat tire or a major drop in inflation pressure in
the indicated tire. A message appears on the
Control Display.
All wheels are yellow
Flat tire or a major drop in inflation pressure in
several tires. A message appears on the Control
Display.
Gray
The system cannot detect a flat tire.
Reasons for this can be:
>TPM is being reset
>Temporary interference due to systems or
devices which use the same radio fre-
quency
>Malfunction

value indicates the current oil level in liters
above Minimum.
After starting the engine, the last determined
value is displayed.
The oil level must be between the two marks.
Manual transmission: the engine oil 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 on the turn signal lever
repeatedly until the oil level display is
shown in the instrument cluster.
4.Press the BC button on 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 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 quarts/liters is displayed by the
oil level measurement. In this area a message 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.
