The instrument cluster gives the driver basic information such as the current
speed, engine speed, the state of some vehicle systems and the like.
If there is a fault in the instrument cluster, the following message will appear
in the display.

Seek help from a specialist garage.
WARNINGConcentrate fully at all times on your driving! As the driver you are fully re-
sponsible for road safety.
Note
■ If the message SAFE CP appears in the instrument cluster display, the compo-
nent protection for the instrument cluster is active. Further information

Revolutions counterRead and observe
on page 28 first.
The tachometer
1
» Fig. 22 on page 28 shows the actual engine speed per
minute.
The beginning of the red scale range of the tachometer indicates the maxi-
mum permitted engine speed of a driven-in and operating warm engine.
You should shift into the next highest gear before the red scale of the revolu- tion counter is reached, or select mode D on the automatic gearbox.
The gear recommendation is important to note in order to maintain the opti-
mum engine speed » page 41.
CAUTION
The pointer of the tachometer must reach the red area for only a short time -
there is a risk of engine damage!

Coolant temperature gauge
Fig. 24
Coolant temperature gauge
Read and observe on page 28 first.
The display » Fig. 24 provides information on the engine coolant temperature.
The fuel gauge only works if the ignition is switched on.
Cold range
If the pointer is still in the left area of the scale, this indicates that the engine has not yet reached its operating temperature. Avoid high speeds, full throttle
and high engine loads. This prevents possible damage to the engine.
The operating range
The engine has reached its operating temperature as soon as the pointer
moves into the middle of the scale
A
» Fig. 24 .
High temperature range
If the pointer reaches the red area of the scale, the coolant temperature is too
high.
CAUTION
■ Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.■
Never cover the radiator - there is a risk of the engine overheating.

Current driving speed
The display is identical to the display on the speedometer.
Average speed
The indication is calculated continuously since the last deletion of the memory.
After erasing the memory, no data will appear for the first 300 m driven.
Distance travelled
The distance travelled since the memory was last erased is displayed.
The maximum distance indicated is 9999 km. The indicator is automatically set
back to zero if this period is exceeded.
Driving time
The time travelled since the memory was last erased is displayed.
The maximum distance indicated is 99 hours and 59 minutes. The indicator is
automatically set back to zero if this period is exceeded.
Convenience consumers
There, the total consumption of all consumer comfort in l / h is displayed.
Along with the consumption data, a list of the three consumers with the larg-
est share of fuel consumption (e.g. air conditioning and similar devices) is dis-
played.
Refuelling amount 1)
After the consumption of about 10 litres of fuel from the fully refuelled tank, an amount of fuel is displayed in l. This amount can now be safely refilled.
Natural gas quality
The details of the quality of natural gas are displayed as a percentage of be-
tween 70% to 100%.
The higher the value of natural gas, the lower is the consumption.
Coolant temperature
If the coolant temperature is in the range 80-110 °C, the engine operating tem-
perature is reached.
If the temperature lies below 80 °C or above 110 °C, avoid high engine revs, full
throttle and high engine loads.Warning when exceeding the set speed

Air outlet vents
116
The heating and air conditioning ventilate and heat the vehicle interior. The air
conditioning system also cools and dehumidifies the vehicle interior.
The heating effect is dependent upon the coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
The cooling system operates only if the following conditions are met. The cooling system is switched on.
The engine is running.
The outside temperature is above approx. +2 °C.
The blower is switched on.
If the cooling system is switched on, the temperature and air humidity drops in the vehicle. The cooling system prevents the windows from misting up during
the cold season of the year.
It is possible to briefly activate recirculated air mode to enhance the cooling
effect » page 115 .
Health protection
To reduce health risks (e.g. common colds), the following instructions for the
use of the cooling system are to be observed. ▶ The difference between the indoor temperature and the outdoor air temper-
ature should not be greater than about 5 ° C.
▶ The cooling system is to be turned off about 10 minutes before the end of
the journey.
▶ Once a year, disinfection of the manual air conditioner or the Climatronic is to
be carried out by a specialist company. 
112Using the system

WARNING■For your own safety and that of other road users, ensure that all the win-
dows are free of ice, snow and misting. The blower should always be on to
prevent the windows from misting up.■
Under certain circumstances, air at a temperature of about 5 °C can flow
out of the vents when the cooling system is switched on.
CAUTION
■ The air inlet in front of the windscreen must be free of e.g. ice, snow or
leaves to ensure that the heating and cooling system operates properly.■
After switching on the cooling Condensation from the evaporator of the air
conditioning may drip down and form a puddle below the vehicle. This is not a
leak!
■
If the coolant temperature is too high, the cooling system is switched off to
ensure that the engine cools down.

Auxiliary heating (auxiliary heating and ventilation)
 Introduction
This chapter contains information on the following subjects:
Switching on/off
118
Radio remote control
119
Functional requirements of the auxiliary heating (auxiliary heating and ventila-
tion)
The charge state of the vehicle battery is sufficient.
The fuel supply is adequate (the warning light  is not illuminated in the
instrument cluster).
Aux. heating
The auxiliary heating can be used when both when stationary, when the en-
gine is switched off, to preheat the vehicle and also while driving (e.g. during
the heating phase of the engine).
The auxiliary heating warms up the coolant by combusting fuel from the vehi-
cle tank. This heats the air flowing into the passenger compartment (if the
blower is turned on).
The auxiliary heating also warms up the engine.
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).WARNING■ The auxiliary heating (auxiliary heating and ventilation) (hereinafter refer-
red to as aux. heating) must never be operated in closed rooms (e.g. garag-
es) – risk of poisoning!■
The auxiliary heating must not be allowed to run during refuelling – risk
of fire.
■
The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. If you want to use the heater, do not park the car in places
where the exhaust fumes can come into contact with flammable materials
such as dry grass, undergrowth, leaves, spilled fuel etc. - risk of fire.
CAUTION
■ The exhaust pipe of the auxiliary heating, which is located on the underside
of the vehicle, must not be clogged and the exhaust flow must not be blocked.■
If the auxiliary heating is running, the vehicle battery discharges.
■
The air inlet in front of the windscreen must be free (e.g. of ice, snow or
leaves) to ensure that the auxiliary heating operates properly. 
