Air outlet vents
98
The heating and air conditioning systems ventilate and heat the vehicle interi-
or. 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 heating and air conditioning systems only operate when the ignition is
switched on.
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 approximately +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
winter months.
It is possible to briefly activate re-circulated air mode to enhance the cooling
effect » page 97 .
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, have the manual air conditioner or Climatronic system disinfec-
ted by a specialist company.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 (e.g. of ice, snow or
leaves) to ensure that the heating and cooling system operates properly.■
After switching on the cooling system 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.

97Heating and ventilation
Drive especially carefully for the first 500 km or so.
New brake pads
New brake pads have to first “grind in” because these do not initially have the
best possible braking effect.
Drive especially carefully for the first 200 km or so.
Tips for economical driving
To achieve the lowest possible fuel consumption, the following instructions
must be observed.
Looking ahead when driving
Avoid unnecessary acceleration and braking.
Change gear in an energy saving and timely manner
Observe the recommended gear » page 39.
Avoid full throttle and high speeds
Fuel consumption can be reduced by half if only three-quarters of the possible
top speed of your vehicle is used.
Reducing idling
If the vehicle is fitted with the START - STOP system there is an automatic re-
duction of the idling. If the engine is stopped on vehicles without START-STOP
system, such as when waiting in a traffic jam, the fuel economy is already
greater after 30 - 40 s than the fuel quantity which is required for engine re-
start.
Avoid short distances
When driving a short distance of less than about 4 km, the engine cannot
reach its operating temperature. As long as the engine has not reached oper-
ating temperature, the fuel consumption is significantly higher than with the
engine hot.
Pay attention to the correct tyre inflation pressure being maintained
Further information » page 161.
Avoid unnecessary ballast
Per 100 kg of weight, consumption increases by about 0.3 l/100 km. At a speed
of 100 - 120 km/h, a vehicle fitted with a roof rack cross member without a load
will use about 10 % more fuel than normal due to the increased aerodynamic
drag.
Saving electricity
Only turn on electrical consumers (e.g. seat, window and mirror heating, etc.)
for as long as necessary.
Use the cooling system economically
The air conditioning system compressor uses power from the engine when in
cooling mode, which will affect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the
interior has been strongly heated through the effect of direct sunlight in order
to allow the heated air to escape.
The cooling system should not be switched on if the windows are open.

Coolant
Introduction
This chapter contains information on the following subjects:
Checking the coolant level
155
Replenishing
155
The coolant provides cooling for the motor.
It consists of water and coolant additive with additives that protect the cooling
system against corrosion and prevents furring.
The coolant additive share in the coolant must be at least. 40%.
The coolant additive may be increased to a maximum of 60%.
The correct mixing ratio of water and coolant additive is to be checked if nec- essary by a specialist garage or is to be restored if necessary.
The description of the coolant is shown in the coolant expansion reservoir » Fig. 169 on page 155 .WARNINGThe engine compartment of your car is a hazardous area. While working in
the engine compartment, be sure to observe the following warnings
» page 149 .■
The coolant is harmful to health.
■
Avoid contact with the coolant.
■
Coolant vapours are harmful to health.
■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurized!
■
When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot
coolant.
■
If any coolant splashes into your eyes, immediately rinse out your eyes
with clear water and contact a doctor as soon as possible.
■
Always keep the coolant in the original container safe from people who
are not completely independent, especially children - there is a danger of
poisoning!
■
Consult a doctor immediately if coolant is swallowed.
■
Never spill operating fluids over the hot engine - risk of fire.
CAUTION
■ Do not continue if for some reason it is not possible to fill with coolant un-
der the current circumstances! Switch off the engine and seek assistance from
a specialist garage.■
With an empty expansion tank top up coolant. The system could ventilate -
there is a risk of engine damage,
not continue! Switch off the engine and
seek assistance from a specialist garage.
■
The amount of coolant additive in the coolant must never be allowed to fall
below 40 %.
■
Over 60 % coolant additive in the coolant reduces the antifreeze protection
and coolant effectiveness.
■
A coolant additive that does not comply with the correct specification can
significantly reduce the corrosion protection of the cooling system.
■
Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage.
■
Do not fill the coolant above the mark
A
» Fig. 169 on page 155 .
■
If an error occurs, leading to the engine overheating, the help of a professio-
nal garage is to be sought - there is a risk of serious engine damage occurring.
154General Maintenance
■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.

In the event of an insufficient coolant level, a control light is displayed on
the instrument cluster, as well as the corresponding message » page 36,
Coolant . We still recommend inspecting the coolant level directly at the reser-
voir from time to time.
ABLoss of coolant
A loss of coolant is first and foremost an indication of a leak in the cooling sys-
tem. Do not merely top up the coolant. Have the cooling system checked by a
specialist garage.
Replenishing
Read and observe
and on page 154 first.
The coolant expansion tank should always contain a small amount of coolant» page 154, in section Introduction .
›
Place a cloth over the cap of the coolant expansion tank and carefully un-
screw the cap.
›
Replenish the coolant.
›
Turn the cap until it clicks into place.
Do not use an alternative additive if the specified coolant is not available. In
this case, use just water and have the correct mixing ratio of water and cool-
ant additive restored by a specialist garage as soon as possible.
Only top up with new coolant.
