Heating, Ventilation and Air conditioning
154Heating, 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 156, fig. 132 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 system also takes solar radiation into
account and, therefore, no subsequent manual readjustments are required.
Therefore, automatic mode ⇒ page 157 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 warmed up sufficiently (this does not
apply to the defrost setting).
In order to achieve maximum engine power, the air conditioning compressor
is tem po ra r ily s witche d o ff whe n pulli ng away f ro m s tan dstill wit h full th rot tle.
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.

Intelligent technology
188Power steeringThe power steering assists the driver when turning the
steering wheel (with the engine running).The power steering assists the driver by reducing the force needed to turn the
steering wheel.
The power steering does not work if the engine is off. In this case the steering
wheel is very hard to turn.
If the steering is held at its turning limit when the car is stationary, this will
place an excessive load on the power steering system. Turning the steering
wheel to its limit places a load on the system, which causes noise. It will also
reduce the idling speed of the engine.
Caution
When the engine is running, do not turn the steering wheel to its limit for
more than 15 seconds. Otherwise, there is a risk of damaging the power
steering.
Note
•If the power steering should fail at any time or the engine is switched off
(for instance when being towed), the car can still be steered. However, more
effort will be required to turn the steering wheel.•If the system is leaking or malfunctioning, please take the car to a quali-
fied workshop as soon as possible.•The power steering requires a special hydraulic fluid. The fluid reservoir is
located at the front of the engine compartment on the left ⇒ page 289. The
correct fluid level in the reservoir is important for the power steering to func-
tion properly. The hydraulic fluid level is checked at the Inspection Service.
ServotronicThe servotronic system electronically adjusts the degree of
power assistanceIn cars equipped with servotronic power steering the degree of power assist-
ance ⇒page 188 is adjusted electronically according to road speed.
If a fault should occur in the servotronic system, the power steering will still
operate. The degree of power assistance will, however, no longer adapt to
different speeds. If the electronic regulating system is not working properly,
this is most noticeable when turning the steering wheel at low speeds (for
instance when parking) – more effort will be required than usual. The fault
should be corrected by a qualified workshop as soon as possible.

Practical tips
Technical Data
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 friction 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 gently, 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 frequently than recommended in the Ser vice
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, the 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 power 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

Driving and the environment
192Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey, you
will not consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of improved fuel efficiency as well as maximum
reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum service tempera-
ture .
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not regularise until having
driven some four kilometres. This is the reason why we recommend avoiding
short trips wherever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressures are just 1 bar too low, this can put the fuel consumption up by
as much as 5%. Due to the greater rolling resistance, under-inflation also
increases tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all year round: they will increase fuel consumption by
up to 10%.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
A roof carrier is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120 km/h your car will use about 12%
more fuel as a result of the extra wind resistance caused by the roof carrier
even when it is not in use. Saving electrical energy
The engine activates the alternator, which produces electricity. With the need
for electricity, fuel consumption is also increased. Because of this, always
turn off electrical equipment when you do not need them. Examples of equip-
ment that use a lot of electricity are: the fan at high speeds, the rear window
heating or the seat heaters*.

Trailer towing
194Trailer towingTrailer towingTechnical requirements
The towing bracket must meet certain technical requirements.Your car is intended mainly for transporting passengers and luggage.
However, if suitably equipped, it can also be used to tow a trailer or caravan.
If your vehicle has been factory -supplied with a towing bracket, all of the
necessary technical and legal aspects for trailing towing have been taking
into account during manufacturing.
Your vehicle is fitted with a 13-pole socket for the electrical connection
between the trailer and the vehicle. If the trailer has a 7-pole connector you
can use an adapter cable. This can be purchased from any SEAT Dealer.
If a towing bracket is to be fitted after the car is purchased, this must be done
according to the instructions of the towing bracket manufacturer
⇒ page 203.
WARNING
If a towing bracket is retrofitted, the installation should be carried out by a
specialist garage.•Particularly in high outdoor temperatures, it is not possible to drive up
long steep gradients without a suitable cooling system. The engine would
heat up.•Incorrect installation can result in a safety risk!
Notes on towing
There are a number of points which need to be checked before
towing a trailer or caravan.– Observe the maximum permitted trailer weights ⇒page 289.Trailer weights
Never exceed the maximum permitted trailer weights.
If you do not load the trailer up to the maximum permitted trailer weight, you
can then climb correspondingly steeper gradients.
The maximum trailer weights listed are only applicable for altitudes up to
1,000 m above sea level. With increa sing altitude the engine power and
therefore the vehicle's climbing ability are impaired because of the reduced
air density. The maximum trailer weight has to be reduced accordingly. The
weight of the car and trailer must be reduced by about 10% for every subse-
quent 1000 m (or part thereof). This figure refers to the combined weight of
the (loaded) vehicle and (loaded) trailer.
The figures for the draw bar weight that appear on the identification plate of
the towing bracket are for certification purposes only. The correct figures for
your specific model, which may be lower than these figures for the towing
bracket, are given in the registration documents and on ⇒page 282. Also
refer to ⇒page 289.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as
possible. Loads carried in the trailer must be secured to prevent them
moving.

Trailer towing195
Safety First
Controls and equipment
Practical tips
Technical Data
Where possible, operate the trailer with the maximum permitted
draw bar
weight on the ball joint of the towing bracket, but do not exceed the specified
limit.
Tyre pressure
Check the tyre pressures on your car, and adjust for “full load” conditions
(refer to the sticker listing the tyre pressures on the door pillar). It may also be
necessary to adjust the tyre pressures on the trailer according to the recom-
mendations of the trailer manufacturer.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case you should have additional mirrors
fitted. The two exterior mirrors should be fitted on folding arms. Adjust the
mirrors to give sufficient rear vision.
Headlights
Before starting a journey, check the headlight beam settings with the trailer
hitched up. If necessary, alter the height of the headlight beams by means of
the headlight range control. See ⇒page 119.
Power supply
When you remove the ignition key, the power supply to the trailer is inter-
rupted.
Removable ball joint coupling
Vehicles with a factory-fitted towing bracket are equipped with a removable
ball joint coupling. This is stored in the spare wheel well in the luggage
compartment together with the necessary fitting instructions.
Note
If you frequently tow, we recommend you also have vehicle ser viced between
services.
Notes on towing
Towing a trailer involves additional attention by the driver.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution.
Speed
The stability of the car and trailer is reduced with increasing speed. Therefore,
it is advisable not to drive at the maximum permissible speed in an unfavour-
able road, weather or wind conditions. This especially applies when driving
downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of swaying . Never try to stop the “snaking” by increasing speed.
Anticipate hazards and brake in good time. If towing a trailer with an inertia
brake , first brake gently and then more severely. This will prevent brake
tapping by the trailer wheels when they lock. Select a low gear in due course
before going down a steep downhill. This enables you to use the engine
braking to slow down the vehicle.
Swaying and pitching can be reduced by stabiliser aids. We recommend
having stabiliser aids installed when towing trailers with a high trailer load.
They can be purchased and installed at a Dealer.
Reheating
When climbing long hills in hot weather with the engine running fast in low
gear, you should keep an eye on the coolant temperature gauge ⇒page 60.
Reduce speed immediately if the needle moves to the right end of the scale.
If the temperature warning light
 in the instrument cluster should start
flashing, stop the car and let the engine cool down by running it at idling
speed for a few minutes.

Your vehicle maintenance and cleaning
210Steel wheel rims– Clean steel wheel rims regularly using a separate sponge.Use an industrial cleanser to remove brake dust. Any damage to the paint on
steel wheel rims should be repaired before starting to rust.
WARNING
•Never wash tyres with a cylindrical jet. Even at large spraying distances
and short cleaning times, visible and invisible damage can occur to the
tyres. This may cause an accident.•Water, ice and salt on the brakes can reduce braking efficiency. Risk of
accident. Directly after washing, avoid sudden and sharp braking. “Dry”
⇒ page 189 the brakes by braking several times.
Cleaning alloy wheel rimsEvery two weeks
– Wash salt and brake dust from alloy wheels.
– Use an acid free detergent to clean the wheel rims.
Every three months
– Apply a hard wax compound to the wheels.Alloy wheels require regular attention to preserve their appearance. If road
salt and brake dust are not often removed, the aluminium finish will be
impaired.
Always use an acid-free detergent for alloy wheel rims. Car polish or other abrasive agents should not be used. If the protective
coating is damaged, e.g. by stone impact, the damaged area should be
repaired immediately.

Underbody maintenance
The vehicle underbody is coated to protect it from chemical
and mechanical damage.The protective coating can be damaged when driving. We recommend you to
check the protective coating under the body and on the running gear, and
reinstated if necessary, before and after the winter season.
We recommend you to go to your Authorised Service Centre to carry out repair
work and additional anti-corrosion work.
WARNING
Do not apply underseal or anti-corrosion coatings to the exhaust pipes,
catalytic converter or the heat shields on the exhaust system. The heat of
the exhaust system or the engine could cause them to ignite! Fire hazard.

Checking and refilling levels217
Safety First
Controls and equipment
Practical tips
Technical Data
−
Insert the fuel nozzle into the mouth of the canister as far as
possible.
− If the spare fuel canister is made of metal, the filling nozzle must be
in contact with the canister during filling. This helps prevent an electro-
static charge building up.
− Never spill fuel in the vehicle or in the luggage compartment. Fuel
vapours are explosive. Danger of death.
Caution
•Fuel spills should be removed from the paintwork immediately.•Never run the tank completely dry. An irregular fuel supply could cause
misfiring. As a result, unburnt fuel could enter the catalytic converter and
cause damage.•When filling the fuel tank after having run it completely dry on a vehicle
with a diesel engine the ignition must be switched on for at least 30 seconds
without starting the engine. When you then start the engine it may take
longer than normal (up to one minute) for the engine to start firing. This is due
to the fact that the fuel system has to purge itself of air before starting.For the sake of the environment
Do not try to put in more fuel after the automatic filler nozzle has switched off;
this may cause the fuel to overflow if it becomes warm.
Releasing the tank flap manuallyThe tank flap can be released manually if the central locking
system fails to operate.–Open the tailgate.
