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 page200.
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.

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

ciency remains available without limita-
tions. While you may continue, you
should remember to proceed cau-
tiously and drive defensively while avoiding full
brake applications. The Tire Pressure Monitor
or the Flat Tire Monitor is also malfunctioning.
Have the system checked as soon as possible.

Technology for comfort, convenience and safety
86
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor detects a pressure loss in
one tire by comparing the speeds of the individ-
ual wheels during driving.
In the event of a pressure loss, there is a change
in the rolling circumference and therefore the
rotation speed of the corresponding wheel. The
system detects this change and reports it 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
*.

The initialization finishes during driving
without feedback.
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 page219.3.Repair flat tire with M Mobility System, refer
to page218, or replace the damaged wheel,
refer to Changing wheels on page220.
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.

Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables better illumination
of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
Activating Adaptive Head Light
With the ignition switched on, turn the light
switch into position 3, refer to page96.
To avoid blinding oncoming traffic, the Adaptive
Head Light is not active when driving in reverse
and points toward the passenger side when the
vehicle is stopped.
High beams/
roadside parking lamps
1High beams
2Headlamp flasher
3Roadside parking lamps
Roadside parking lamps, left or right*
You also enjoy the option of lighting up just one
side of your vehicle when parking:
Switching on
After parking the vehicle, press the lever up or
down beyond the resistance point, arrow 3.
The roadside parking lamps drain the bat-
tery. Do not leave them switched on for
long periods of time, otherwise it may no longer
be possible to start the engine.<
Switching off
Briefly press the lever in the opposite direction
up to the resistance point, arrow3.
High-beam assistant*
The concept
This system automatically switches the high
beams on and off. A sensor on the front side of
the inside rearview mirror controls the process.
The assistant makes sure that the high beams
are switched on whenever traffic conditions
permit. This relieves you of the burden of con-
stantly switching back and forth and simulta-
neously provides you with the best possible vis-
ibility. Naturally, you can intervene at any time to
switch the high beams on and off as usual.
Activating system
1.Turn the light switch to position3, refer to
page96.
2.With the low beams switched on, briefly
press the turn signal lever in the high-beam
direction.
The indicator lamp in the instrument
cluster lights up when the high-beam
assistant is activated. The system
automatically switches between high beams
and low beams, reacting to oncoming traffic,
vehicles ahead of you, and sufficiently lit areas,
e.g. in built-up zones.

style and driving conditions.
Checking engine oil level
Your vehicle is equipped with an electronic oil
level check.
The oil level can be displayed when the engine
is at operating temperature. Constant short-
distance driving or a very sporty driving style
can make it impossible for a measurement to be
taken.
