CD, radio and telephone* display
Fig. 48 Display: addi-
tional radio information
If the radio is switched on and no Priority 2 faults are indicated by the auto-
check control, depending on the type of radio fitted, the display will show
the name or frequency of the selected radio station and complementary in-
formation, once the “OK” symbol has gone out.
When in CD mode*, the display will show the current track.
If you have a compatible telephone*, the phone book or telephone dialled
can also be seen on this display.
These displays appear in addition to the display on the radio itself. Outside temperature displayFig. 49 Display: Outside
temperature display
The outside temperature is shown in the display when the ignition is switch-
ed on ⇒ fig. 49. In vehicles with an automatic gearbox, the display does not appear until the driver has engaged a gear.
At temperatures below +5 °C a snowflake symbol appears next to the tem-
perature display. This is to warn the driver to take extra care when there is a
risk of ice on the road. When the vehicle is stationary or travelling at very
low speeds, the temperature displayed may be slightly higher than the ac-
tual ambient temperature as a result of heat coming from the engine.
If the vehicle has an air conditioner and the display is changed over to °F
(degrees Fahrenheit), the outside temperature display automatically
changes over to °F ⇒ page 167.
WARNING
Do not rely on the outside temperature display as an ice warning. Please
bear in mind that there may be ice on the roads even at outside tempera-
tures of +5 °C – beware of ice patches.
80Cockpit
Yellow symbols are accompanied by one warning buzzer. The function indi-
cated should be checked as soon as possible. If several Priority 2 faults are
detected at the same time, the symbols are displayed one after the other for
about 2 seconds at a time.
Brake light failure
This warning light will appear on the upper part of the display if any of the
brake lights has failed. A text message in the central part of the display indi-
cates which brake light has failed (left or right).
Fuel level low
When this symbol comes on for the first time, there are about 8 to 10 li-
tres of fuel left in the tank. You should fill up as soon as possible
⇒ page 222.
Engine speed governing
Max. engine speed XXXX rpm
There is a fault in the engine management. In addition, the warning lamp
on the instrument panel will light up. The engine speed will be governed to
the speed displayed in the driver information system. Please ensure that
the engine speed does not exceed the speed shown (for example, when
changing down a gear).
Take the vehicle to a qualified workshop immediately to have the fault re-
paired. Checking the engine oil level
If the symbol lights up, please check the engine oil level as soon as pos-
sible ⇒ page 229. Top up the oil at the next opportunity ⇒ page 230.
Engine oil sensor defective*
If the symbol lights up, take the vehicle to a qualified workshop and
have the oil level sensor checked. Until then it is advisable to check the oil
level every time you fill up with fuel ⇒ page 229.
Diesel particulate filter obstructed
If the symbol lights up, you can contribute towards automatic filter
cleaning by driving in the right manner. To do this, drive about 15 minutes
in 4th or 5th gear (automatic gearbox: S gear range) at a speed of 60 km/h,
with the engine running at approximately 2000 rpm. The increase in temper-
ature will burn off any soot in the filter. When cleaning is successful, the
symbol switches off.
If the symbol does not turn off, or the three lamps turn on (particulate
filter , emission control system fault and heaters ), take the vehicle
to a qualified workshop to repair the fault.
For further information on the diesel particulate filter, see ⇒ page 198.
WARNING
It is essential that you adjust your speed to suit the weather, road, ter-
rain and traffic conditions. The recommended driving speed must never
lead to the driver disregarding the traffic regulations.

Air conditioning
Air conditioning 2C-Climatronic
Description
The air conditioner is designed to automatically keep the
passenger compartment at the temperature you find most
comfortable at all times of the year. Recommended settings:
– Set the temperature to 22 °C (71 °F).
– Press the AUTO
⇒ fig. 141 button.
The following setting quickly provides a comfortable temperature inside the
vehicle. We therefore recommend you do not modify the setting unless you
find this temperature uncomfortable or where circumstances require as
such.
The air conditioner provides heating and ventilation and also cools and de-
humidifies the air inside the vehicle.
The air conditioner is fully automatic and will constantly maintain the tem-
perature which has been set. To achieve this, the temperature of the air sup-
plied to the interior, the blower speed (volume of air delivery) and the air
distribution are regulated automatically. The system also takes solar radia-
tion into account and, therefore, no subsequent manual readjustments are
required. Therefore, automatic mode ⇒ page 164 should be used for the
comfort of all the passengers in virtually all conditions throughout the year.
Please note the following points: The humidity of the air is automatically reduced when the system cools the
interior of the vehicle. This helps to prevent condensation on the windows.
If the humidity and temperature outside the vehicle are high,
condensation
can drip off the evaporator in the air cooling system and form a pool under-
neath the vehicle. This is normal and does not indicate a leak.
If the outside temperature is low, the blower normally only switches to a
higher speed once the coolant has warmed up sufficiently (this does not ap-
ply to the defrost setting).
In order to achieve maximum engine power, the air conditioner compressor
is temporarily switched off when pulling away from standstill with full throt-
tle.
The compressor also switches off if the coolant temperature is excessively
high to ensure adequate engine cooling under extreme loads.
Pollution filter
The pollution filter (a combined particulate filter and activated charcoal fil-
ter) serves as a barrier against impurities in the outside air, including dust
and pollen.
For the air conditioner to work with maximum efficiency, the pollution filter
element must be replaced at the intervals specified in the Service Plan.
If the vehicle is driven in areas with a high level of air pollution and the filter
is no longer fully effective, it may be necessary to change the filter element
more frequently.

162Air conditioning
CAUTION
● If you suspect that the air conditioner system is damaged, switch over to
ECON mode to prevent further damage and have the system checked by a
qualified workshop.
● Repairs to the air conditioner require specialist knowledge and special
tools. For this reason, please contact a qualified workshop if the system is
not working properly.
Note
● Keep the air intake slots in front of the windscreen clear of snow, ice and
leaves to ensure unimpaired heating and cooling and to prevent the win-
dows misting over.
● The air from the outlets flows through the passenger compartment and
out through the slots below the rear window. Therefore, do not cover these
slots with items of clothing or other objects.
● The air conditioner operates most effectively with the windows and the
sliding/tilting sunroof* closed. However, if the vehicle has heated up after
standing in the sun for some time, the air inside can be cooled more quickly
by opening the windows briefly.
