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.

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. A Check
Control message of this kind includes indicator
or warning lamps in the instrument cluster, pos-
sibly 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.
This symbol means that a Check Control
message has been generated. The symbol
remains visible even if the Check Control mes-
sage has been hidden after a short time. The
combinations of warning lamps and text mes-
sages are stored and can be viewed later, also
refer to page74.

change. This change is detected and signaled
as a flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be repeated after
every correction of the tire inflation pres-
sure 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 snow-covered or slippery roads
>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 auto-
matically continued.
Do not initialize the system when driving with
snow chains
*.<

Indication of a flat tire
The warning lamp lights up in red. A
message appears on the Control Dis-
play. 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 page214.
3.Repair flat tire with M Mobility System, refer
to page212, or replace the damaged wheel,
refer to Changing wheels on page215.
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.

Engine oil
Engine oil consumption depends on driving
style and driving conditions.
Checking engine oil level
Your vehicle is equipped with an electronic oil
level check. You can display the oil level in the
instrument cluster.
1Oil level
2Maximum marking
3Minimum marking
Press the BC button in the turn signal lever
repeatedly until the oil level display is shown in
the instrument cluster. The displayed numeric
value indicates the current oil level in liters
above Minimum.
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.
