pacity and with the same driving style. If you drive more efficiently this value
can increase. With G-TEC vehicles the following details are displayed - total
range / with natural gas / petrol.
Average fuel consumption - Is calculated continuously since the last time that
the memory was erased. After erasing the memory, no data will appear for the
first 100 m driven. With G-TEC vehicles, the average consumption of fuel cur-
rently being used is displayed.
Current fuel consumption - When the vehicle is stationary or moving slowly,
the fuel consumption is displayed in l/h (in models in some countries the fol-
lowing appears --,- km/l). With G-TEC vehicles the current consumption of the
fuel currently being used is displayed ( with regards to a stationary or slow
moving vehicle, the natural gas consumption is displayed in kg/h).
Oil temperature if the temperature is lower than 50 °C or if there is a fault in
the system for checking the oil temperature, the  symbols are displayed.

porting cargo on the roof rack.■
Always distribute the load on the roof rack evenly and secure properly
with suitable lashing straps or tensioning straps.
■
When transporting heavy objects or objects which take up a large area on
the roof rack system, the handling of the car may change as a result of the
displacement of the centre of gravity. The style of driving and speed must
therefore be adapted to the current circumstances.
■
The permissible roof load, permissible axle loads and gross permissible
weight of the vehicle must not be exceeded under any circumstances – risk
of accident!
CAUTION
■ Before stowing the roof rack, the key must be removed from the carrier -
otherwise there is a risk of key corruption.■
If you want to stow the roof rack and the roll-up luggage compartment cover
at the same time , then it is necessary that the rear part of the roll-up luggage
compartment is covering the rear roof rack.
CAUTION
■
Make sure that the sliding / tilting roof or the boot lid does not collide with
the roof load when opened.■
Ensure the roof aerial is not impaired by the load being transported.

The heater heats and ventilates the vehicle interior. The air conditioning sys-
tem 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 works under the following conditions. The cooling system is switched on.
The engine is running.
The outside temperature is above 2 °C.
The blower is switched on.
When the cooling system is switched on, it prevents misting of the windscreen
and windows.
It is possible to boost the effectiveness of the cooling system by briefly acti-
vating the air recirculation system » page 107.
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 outside temperature and the inside temperature
should not be greater than 5 °C.
▶ The cooling system should be turned off about 10 minutes before the end of
the journey.
▶ Once a year, a disinfection of the air conditioner must be carried out by a
specialist company. 
104Using the system

WARNING■The blower should always be on to prevent the windows from misting.
Otherwise there is a risk of an accident.■
Under certain circumstances, air at a temperature of about 5 °C can flow
out of the vents when the cooling system is switched on.
Note
■ 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.

Coolant
 Introduction
This chapter contains information on the following subjects:
Checking and refilling
257
The coolant helps to keep the engine temperature down, and consists of wa-
ter and coolant additive (with additives that protect the cooling system against
corrosion and prevent furring).
The proportion of coolant additive in the coolant must be 40 to 60 %.
The correct mix of water and coolant additive should be checked and if neces-
sary corrected by a specialist garage.
WARNING■ The following instructions must be followed at all times when working on
the engine compartment » page 252.■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurised - risk of scalding or
injury from splashes of coolant!
■
To protect against the coolant splashing, cover the cap with a cloth when
opening.
■
Coolant and coolant fumes are harmful - avoid contact with the coolant. If
the coolant comes into contact with the eye or skin, wash the affected area
with plenty of water for several minutes, and where appropriate seek medi-
cal help.
CAUTION
Do not cover the radiator and install any parts (e.g auxiliary lights.) in front of
the air intakes - There is a risk of the engine overheating.256General Maintenance
