Engine revolutions counterThe red zone of the rev counter scale
⇒page 17, fig. 17
indicates the range in
which the engine control unit begins to li
mit the engine speed. The engine control
unit restricts the engine speed to the steady limit value. Shift into the next higher gear or select
the selector lever position D of the auto-
matic gearbox before reaching the red zone of the rev counter scale. Avoid high engine speeds during the driv
ing time and before the engine has been
warmed up to operating temperature
⇒page 201.
For the sake of the environment
Shifting up early helps you save fuel and reduce the operating noise of your vehicle.SpeedometerWarning against excessive speeds* An acoustic warning signal will sound when the vehicle speed exceeds 120 kilome- tres per hour. The acoustic warning signal
will switch off ag
ain when the vehicle
speed goes below this speed limit.
Note
This function is only valid for some countries.Coolant temperature gaugeThe coolant temperature gauge
⇒page 17, fig. 17
operates only when the igni-
tion is switched on. In order to avoid any damage to the engine
, please pay attentio
n to the following
notes regarding the temperature ranges:
Cold range If the pointer is in the left-hand area of the scale it means that the engine has not yet reached its operating temperature. Avoi
d running at high engine speeds, at full
throttle and at severe engine loads. The operating range The engine has reached its operating temperature as soon as the pointer moves into the mid-range of the scale. The pointe
r may also move further to the right at
high engine loads and high outside temper
atures. This is not critical provided the
warning symbol
in the instrument cluster does not flash.
If the symbol
in the instrument cluster flashes it means that either the coolant
temperature
is too high or the coolant
level
is too low. Observe the guidelines
⇒ page 38, “Coolant temperature/ Coolant quantity
”.
WARNING
Pay attention to the warning notes
⇒page 223, “Working in the engine
compartment” before opening the bonnet and inspecting the coolant level.
Caution
Additional headlights and other attached co
mponents in front of the fresh air inlet
impair the cooling efficiency of the coolant. There is then a risk of the engine over-heating at high outside temperatures and high engine loads!Fuel gaugeThe fuel gauge
⇒page 17, fig. 17
only operates when th
e ignition is switched
on. The fuel tank has a capacity of about 60 litres. The warning symbol
in the instru-
ment cluster lights up when the pointer reaches the reserve marking. There are now about 9 litres of fuel remaining in the tank. This symbol is a reminder for you,
that
you must refuel

lights up, when operating the speed regulating system.
Failure of the light bulbs
The warning light
comes on if a light bulb is damaged:
•
up to 2 seconds after the ignition is switched on,
•
when switching on the defective light bulb.
The following text e.g will be displayed in the information display*:
Check front right dipped beam!
The rear side lights and the licence plate
lighting require several light bulbs. The
indicator light
only lights up if all light bulbs
of the licence plate lighting or the
parking light (in one rear light unit) are defe
ctive. Check regularly the function of the
light bulbs.Adaptive headlights*
If the warning light
flashes for 1 minute while driving or after switching on the
ignition and a warning signal sounds, a fault of the adaptive headlights is confirmed. Further information
⇒page 63.
Diesel particle filter*
(diesel engine)
If the warning light
comes on, this means that soot has accumulated in the
diesel particle filter because of the frequent short distances. In order to clean the diesel particle filter,
the vehicle should be driven at an even
speed of at least 60 km/h at engine speeds of 1 800 - 2 500 rpm for at least 15 minutes or until the warning light goes out with the 4th or 5th gear engaged (auto-matic gearbox: position S) when the traffi
c situation permits it. This increases the
exhaust temperature and the soot deposited in the diesel particle filter is burnt. Always pay attention to the valid speed limits
⇒
.
The warning light
goes out after the successful cleaning of the diesel particle
filter. If the filter is not properly cleaned, the warning light
does not go out and the
warning light
begins to flash. In the in
formation display* appears
Diesel-
particle Owner's manual
. Afterwards the engine control unit shifts the engine into
the emergency mode, which only has a re
duced power output. After switching the
ignition off and on again the warning light
comes on.

The light sensor switches on the full ou
ter illumination at low light intensity.
System AHL* makes it possible to change
the length and width of illumination of
the headlight. The length and width of i
llumination changes automatically in rela-
tion to the vehicle speed and the use of the windscreen wiper. System AHL* operates in the following modes. Mode out of town The mode “out of town” is a basic mode. The dispersion of the cone of light in front of the vehicle is similar to the low beam. The mode is active if none of the following modes are active. Mode rain In the mode “rain” the dispersion of the cone of light in front of the vehicle is wider and the width of illumination is shorter,
so that during bad weather (rain) the
dazzling of the oncoming drivers can be reduced. The mode is activated at speeds of 15 - 70 km/h and if the windscreen wi
pers continuously operate for a period of
time longer than 2 minutes. The mode
is deactivated when dropping below or
exceeding the set speed limit or if the windscreen wipers have been switched off for a period of time longer than 8 minutes.

Mode city In the mode “city”, the dispersion of the cone
of light in front of the vehicle is wider
and the width of illumination is shorter. It
has as an aim to il
luminate the adjacent
footpaths, crossings, pedestrian crossings etc. The mode is active at speeds of 15 - 50 km/h. Mode motorway In the mode “motorway” the disp
ersion of the cone of light is so widespread, that it
illuminates also the left (and right)
7) lane of the motorway, so that the driver can
react in time to an obstacle or any other
danger. The mode is activated stepwise as
of a speed of 90 km/h. It gains its greate
st effectiveness at speeds above 120 km/h.

Winter position If the windscreen wipers are in rest posi
tion, they cannot be folded out from the
windscreen. For this reason we recommend
adjusting the windscreen wipers in
winter so that they can be folded out fr
om the windscreen easi
ly. You can set this
rest position as follows:•
Switch on the windscreen wipers.
•
Switch off the ignition. The windscreen wi
pers remain in the position in which
they were when switching off the ignition. You can also use the service po
sition as a winter position.
WARNING
•
Properly maintained windscreen wiper
blades are essential for clear visi-
bility and safe driving
⇒page 74.
•
Do not use the windscreen washer sy
stem at low temperatures, without
heating the windscreen beforehand. Otherwise the window cleaner could freeze on the windscreen and re
strict the view to the front.
•
The rain sensor only operates as a
support. The driver is not released
from the responsibility to set the function of the windscreen wipers manu- ally depending on the visibility conditions.
Caution
In frosty weather, please first of all chec
k whether the windscreen wiper blades are
not frozen to the windscreen before swit
ching them on. Switching on windscreen
wipers when the blades are frozen to the windscreen may result in damage both to the blades and the motor of the windscreen wipers!
Note
•
If the slower or the faster wiper setting is switched on
⇒page 73, fig. 73
and the vehicle speed decreases to below 4
km/h, the lower wiper step is switched
on automatically. At a speed increase of
more than 8 km/h the previous wiper
setting is established again.
•
If there is an obstacle on the windscreen, the wiper will try to push away the
obstacle. If the obstacle continues to bloc
k the wiper, the wiper stops after 5 cycles,
in order to avoid a damage to the wiper.
Remove the obstacle and and switch on
the wiper again.Headlight cleaning system*The headlights are being cleaned after the
windscreen has been sprayed for the first
time and fifth time, the low beam or ma
in beam are switched on and the wind-
screen wiper lever was held in the position
⇒page 73, fig. 73
for about 1
second. The headlight washer nozzles are moved fo
rward out of the bumper by the water
pressure for cleaning the headlights. You should remove stubborn dirt (such
as insect residues) from the headlight
lenses at regular intervals, for example when refuelling. Please refer to the following guidelines. You should remove any snow from the fixtures of the washer nozzles and clear ice in winter with a de-icing spray in order to ensure proper operation of the cleaning system.Replacing wiper blades for the windscreen wipers
