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 page174.
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.<

EDC Electronic Damping
Control
The concept
If the influencing variables such as road surface
quality or operating conditions such as steer-
ing, braking etc. change, the damping automat-
ically adjusts to the new conditions within a
fraction of a second.
You can choose from three programs.
"Comfort" program
Select the "Comfort" program if you want com-
fort-oriented coordination of shock absorbers
and steering.
"Normal" program
The "Normal" program offers a balanced mix-
ture of the comfort and the sport program.
"Sport" program
Select the "Sport" program if you want a con-
sistently sporty coordination of shock absorb-
ers and steering.
Selecting program
Press the EDC button repeatedly:
>"Comfort": no LED lights up in the button.
>"Normal": one LED lights up in the button.
>"Sport": both LEDs light up in the button.
The last selected program is active each time
the engine is started.
You can also activate your preferred program
with the button on the steering wheel, refer
to MDrive on page48.
Flat Tire Monitor FTM
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the tires as you drive. The sys-
tem provides an alert whenever the inflation
pressure drops significantly in relation to the
pressure in another tire.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels
change. This change is detected and is
reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The initialization must be repeated after
each time the tire inflation pressure is cor-
rected and after every tire or wheel change.<

any time and switch the high beams on and off
in the accustomed manner.
Activating high-beam assistant
1.Turn the light switch to switch position3,
refer to page83.
2.Press the turn signal lever in the high beam
direction with the low beams switched on.
The indicator lamp in the instrument
cluster lights up when the high-beam
assistant is activated. The assistant
automatically switches between high and low
beams, whereby the system reacts to oncom-
ing traffic and traffic ahead, as well as to suffi-
cient lighting, e.g. towns/cities.
Manually switching between high and
low beams
You can intervene at any time if you wish or the
situation requires.
>If the high-beam assistant has switched on
the high beams, however you nevertheless
want to use the low beams, simply switch to
the low beams with the turn signal lever.
The high-beam assistant is deactivated in
the process.
To reactivate the system, briefly press the
turn signal lever in the high beam direction
again.
>If the high-beam assistant has switched on
the low beams, however you nevertheless
want to use the high beams, switch to the
high beams in the accustomed manner. The
system is deactivated in the process and
you must switch to the low beams manually.To reactivate the system, briefly press the
turn signal lever in the high beam direction
again.
>You use the headlamp flasher as usual with
low beams.
System limits
The high-beam assistant cannot replace
personal decisions on the benefits of
using the high beams. In situations which
require this, you should therefore switch to the
low beams manually to avoid a safety risk.<
In the following example situations, the system
does not operate or only with limitations and a
personal reaction may be required:
>Under extremely unfavorable weather con-
ditions, such as fog or heavy precipitation
>For perceiving road users with poor lighting
of their own, e.g. pedestrians, cyclists, peo-
ple on horseback, horse-drawn vehicles,
with train or ship traffic close to the road and
wild animals crossing the road
>In tight curves, on steep crowns or depres-
sions, with cross traffic or partially con-
cealed oncoming traffic on the freeway
>In poorly lit places and with highly reflective
signs
>In the low speed range
>When the windshield is fogged up, dirty or
covered with stickers, vignettes etc. in the
area of the inside rearview mirror
>When the sensor is dirty. Clean the sensor
on the front side of the inside rearview mir-
ror with a cloth moistened with a small
amount of glass cleaner

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.
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 too high
Have the vehicle checked immedi-
ately, otherwise engine damage may
result if too much oil has been added.<
4Oil level at maximum
5Quick 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.
