Heating, Ventilation and Air conditioning
152Heating, Ventilation and Air conditioning2C-ClimatronicDescription
The climate control 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 ⇒page 154, fig. 133 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 climate control provides heating and ventilation and also cools and
dehumidifies the air inside the vehicle.
The climate control is fully automatic and will constantly maintain the temper-
ature which has been set. To achieve this, the temperature of the air supplied
to the interior, the blower speed (volume of air delivery) and the air distribu-
tion are regulated automatically. The sy stem also takes solar radiation into
account and, therefore, no subsequent manual readjustments are required.
Therefore, automatic mode ⇒ page 155 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 warm ed up sufficiently (this does not
apply to the defrost setting).
In order to achieve maximum engine power, the air conditioning compressor
is temporarily switched off when pulling away from standstill with full throttle.
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 particle filter and activated charcoal filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the climate control to work with maximum efficiency, the pollution filter
element must be replaced at the intervals specified in the Service Schedule.
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.
Caution
•
If you suspect that the climate control system is damaged, switch over to
ECON mode to prevent further damage and have the system checked by a
specialist garage.
•
Repairs to the climate control require specialist knowledge and special
tools. For this reason, please contact a specialist garage if the system is not
working properly.

Driving and the environmentRunning-inRunning in a new engine
The engine needs to be run-in over the first 1,500 km.Up to 1,000 kilometres
– Do not drive at speeds of more than 2/3 the maximum speed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1000 to 1500 km
–Speeds can be gradually increased to the maximum road speed
or maximum permissible engine speed (rpm).During its first few hours of running, the internal fric tion in the engine is
greater than later on, when all the moving parts have bedded in.
For the sake of the environment
If the engine is run in gent ly, its life will be increased and its oil consumption,
reduced.
Braking effect and braking distance
The braking effect and braking distance are influenced by
driving situations and road conditions.The efficiency of the brakes depends directly on the brake pad wear. The rate
of wear of the brake pads depends to a great extent on the conditions under
which the vehicle is operated and the way the vehicle is driven. If you often
drive in town traffic, drive short distances or have a sporty driving style, we
recommend that you have the thickness of your brake pads checked by an
Authorised Service Centre more freque ntly than recommended in the Service
Schedule.
If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the car, the effect of the brakes is less-
ened as the brake discs are wet or even frozen (in winter): The brakes should
be “dried” by pressing the pedal to restore full braking effect.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.•
New brake pads must be run in and do not have the correct friction
during the first 200 km. However, th e reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. This also
applies when new brake pads are fitted.
•
If brakes are wet or frozen, or if you are driving on roads which have
been gritted with salt, braking po wer may set in later than normal.
•
On steep slopes, if brakes are excessively used, they will overheat.
Before driving down a long steep slope, it is advisable to reduce speed and
change down into a lower gear (or move the selector lever to a lower gear if

NoteOn right-hand drive vehicles some of the containers/ reservoirs mentioned
below are located on the other side of the engine compartment.Closing the bonnet– To close the bonnet, pull it down to overcome the spring pres- sure.
– Leave the bonnet secured in the locking part. Do not tighten
⇒ .
WARNING
•
For safety reasons the bonnet must always be completely closed when
the vehicle is moving. After closing it always check that it is properly
secured. The bonnet must be flus h with the adjacent body panels.
•
Should you notice that the bonnet is not safely secured when the
vehicle is moving, stop the vehicle immediately and close the bonnet.
Failure to do so could result in an accident.
Engine oilGeneral notesWe recommend you to entrust the oil change with your Technical Service or a
qualified workshop, according to the Maintenance Program. The correct oil specifications for your engine are listed in the
Technical data
section ⇒page 282.
Check that the specifications quoted (VW standards) appear on the container
either singly or in combination with other specifications.
Fixed service intervals*
You can use oils for service intervals - ⇒ page 282. In this case, your car must
be serviced after a fixed interval of 1 year / 15,000 km (10,000 miles) see
Service Schedule.
•
In exceptional circumstances, if the engine oil level is too low
⇒ page 215 and you cannot obtain the oi l specified for your vehicle, you can
put in a small quantity of oil conforming to the specification ACEA A2 or
ACEA A3 (petrol engines) or ACEA B3 or ACEA B4 (diesel engines) (up to 0.5l).
Vehicles with diesel particulate filter*
The Service Schedule states whether your vehicle is fitted with a diesel partic-
ulate filter.
•
Vehicles with a diesel particulate filter must only b e f ill e d wi th VW 507 00
engine oil.
•
Avoid mixing this oil with other engine oils.
•
Only in exceptional circumstances, if the engine oil level is too low
⇒ page 215 and you cannot obtain the oi l specified for your vehicle, can you
put in a small quantity of oil (once) conforming to the VW 506 00, VW 506 01,
VW 505 00, VW 505 01 or ACEA B3 / ACEA B4 specification. (up to 0.5l).

Topping up and changing the brake fluid
It is best to have the brake fluid changed by a professional.Brake fluid absorbs damp. Therefore, in the course of time it will absorb water
from the ambient air. If the water content in the brake fluid is too high, the
brake system could corrode. In addition, the boiling point of the brake fluid
will be considerably reduced. This could adversely affect the braking ability in
certain circumstances.
For this reason the brake fluid must be changed periodically.
Your vehicle's Service Schedule will tell you when the brake fluid has to be
renewed.
We recommend you have the brake fluid changed as part of a regular Inspec-
tion Service at your garage. They are familiar with the procedure and have the
necessary special tools and spare parts as well as the proper facilities for
disposing of the old fluid.
Use only the genuine brake fluid specified by the factory Specialist garages
know that the brake fluid -DOT 4- is factory approved. The brake fluid must be
new.
WARNING
•
Therefore, it must always be kept closed in its original container. Keep
out of the reach of children. Failure to comply could result in poisoning.
•
Heavy use of the brakes may cause a vapour lock if the brake fluid is left
in the system for too long. This would seriously affect the efficiency of the
brakes and the safety of the car, leading to the risk of accident.Caution
Please note that brake fluid will attack the paintwork on contact.
For the sake of the environment
If the fluid has to be drained out of the brake system, use an appropriate
container to catch the used brake fluid and dispose of it in the proper
manner.BatteryGeneral notes
All work on batteries requires specialist knowledge.The battery is virtually maintenance-free and is checked in the Inspection
Services.
We recommend that you replace a battery once it is older than 5 years.
Disconnecting the battery
If the battery is disconnected, some of the vehicle's functions will become
inoperative (e.g. electric windows). These functions will require resetting
after the battery is reconnected. For th is reason, the battery should only be
disconnected from the vehicle's electr ical system when absolutely necessary.
Long periods of non-use
The battery will gradually lose its charge because certain electrical equip-
ment continues to draw current even when the ignition is off. If you park the
vehicle for long periods of time in winter you should take the battery out of
the vehicle and keep it in a frost-proof room. Store the battery in a place
where it cannot “freeze up” and become damaged. At warm outside temper-
atures it is sufficient to disconnect the negative terminal of the battery. Even
when the battery is not connected you should charge it from time to time.
