Heating, Ventilation and Air conditioning157
Safety FirstOperating instructionsTips and MaintenanceTe c h n i c a l D a t a Air vents in the roof
In vehicles with a second cooling system
39) for ventilating the passenger
compartment, an air outlet is fitted in the roof above each rear seat
Ÿfig. 122.
The air outlets in the roof can be opened and closed individually and
adjusted by moving the grid.
Each air outlet has two thumb wheels. The left thumb wheel can be used to
open and close the air outlet. The right thumb wheel can be used to direct the
air towards the head and chest.
WARNING
Never leave objects, food or medicines in front of the air outlets in the rear
seats. The hot air could damage or destroy heat-sensitive objects, food or
medicines.
Caution
Do not use the area in front of the outlets to store objects. This could cause
the blower to overheat and switch off. The blower could also be damaged.
Note
In the cooling mode, at least one air outlet in the roof must be open. The
cooling system could otherwise ice over.
General notes
The pollen filter
The pollution filter serves as a barrier against impurities in the ambient air
(e.g. dust and pollen).
For the air conditioning system to work with maximum efficiency, the pollen
filter must be replaced at the intervals specified in the Service Schedule.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, the pollen filter must be changed more frequently than
stated in the Service Schedule.
Instructions for use
If the air conditioning or Climatronic
40) is not switched on for a long period,
deposits on the evaporator can cause unpleasant smells. To prevent these
odours, the cooling system should be run at the highest blower setting at
least once a month when temperatures are over +5°C. Briefly open a window
at the same time.
Faults in the operation of the air conditioning
There is a fault if the all the symbols in the Climatronic flash for approx. 15
seconds when the ignition is switched on. Contact a specialist workshop.
If the air conditioning system cannot be switched on this may be caused by
the following reasons:
•the engine is not running.
•The blower is switched off.
•The outside temperature is lower than +5°C.
•the cooling system compressor has been temporarily switched off
because the engine coolant temperature is too high.
•The air conditioner fuse is faulty.

Driving and the environment
Running-in
Running 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 faster than three quarters of top speed.
– Do not use full throttle.
– 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 friction in the engine is
greater than later on when all the moving parts have bedded down.
For the sake of the environment
If the engine is run in gently, the life of the engine will be increased and its oil
consumption reduced.
Running in tyres and brake pads
New tyres should be run-in carefully for the first 500 km. New
brake pads should be run-in carefully for the first 200 km.
During the first 200 km, you can compensate for the reduced braking effect
by applying more pressure to the brake pedal. If you need to make an emer-
gency stop, the braking distance will be longer with new brake pads than with
brake pads which have been run-in.
WARNING
•New tyres do not give maximum grip to start with, and need running in.
This may cause an accident. Drive particularly carefully in the first 500 km.
•New brake pads must be “run in” and do not have the correct friction
properties during the first 200 km. However, you can compensate for the
slightly reduced braking effect by applying more pressure on the brake
pedal.
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 SEAT
Service more frequently than recommended in the service schedule.
