Air conditioning
Economic use of the air-conditioning
sy s
t
em When the air conditioning is switched on, the
compr
e

ssor consumes engine power and has
influence on fuel consumption.
If the vehicle interior has overheated due to
excessive solar radiation, it is best to open
the windows or doors to allow the hot air to
escape.
While in motion, the air conditioning should
not be switched on if the windows are open. If the interior temperature can be reached
without
sw

itching on the air conditioning, the
fresh air mode should be used. For the sake of the environment
Saving fuel reduces emissions. Faults
If the air conditioning does not work at out-
side t
emper

atures above +5°C (+41°F) then the system is faulty. This may be due to one
of the f
o

llowing reasons:
● One of the fuses has blown. Check the fuse
and repl
ace if necessary ››› page 80.
● The air conditioning compressor has
switc
hed off temporarily because of in-
creased engine coolant temperature
››› page 97.
If you cannot repair the fault yourself or
where cooling power continues to drop,
switch off the system. Contact a specialised
service.

Climatronic automatically maintains a com-
fortable temperature. To do so, it automati-
cally regulates the supplied air temperature
and the blower and air distribution levels.
The system also allows for the effect of sun-
light, so there is no need for manual adjust-
ment. It also has a humidity sensor that
helps to automatically demist the wind-
screen.

Economical and environmentally-

g Fuel consumption, environmental pollution
and we
ar t

o the engine, brakes and tyres de-
pends in large part on your driving style. By
adopting an economical driving style and an-
ticipating the traffic situation ahead, you can
easily reduce fuel consumption by 10-15%.
Some tips on how to help you reduce pollu-
tion while saving money are listed below.
Drive anticipating the traffic situation
A vehicle uses most fuel when accelerating.
When you anticipate situations, you have to
brake less often and, thus, accelerate less. If
it is possible, let the vehicle roll with a gear
engaged, for example, if you see a red light
ahead. The braking effect achieved in this
way helps to reduce the wear of brakes and
tyres; emissions and fuel consumption are
reduced to zero (disconnection due to iner-
tia).
Change gear early to save energy
An effective way of saving fuel is to change
up quickly through the gears. Running the

Towing bracket device
Driving with a trailer Exterior mirrors
Check
whether
you can see enough of the
road behind the trailer with the standard rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Observe the relevant statutory requirements
of the country you are in.
Headlights
Before starting a journey, also check the
headlight beam settings with the trailer
hitched up. Adjust the headlight range set-
tings if necessary ›››
page 117, Main light
range control .
Driving speed
For your own safety do not drive faster than
the maximum permitted speed indicated on
the trailer.
At all times, immediately reduce speed if you
detect the slightest swaying movement of the
trailer. Never try to “return the trailer to a
straight position” by accelerating.
Brakes
Brake in due course! If the trailer has an over-
run brake, apply the brakes gently at first and
then, firmly. This will prevent the jerking that
can be caused by locking of trailer wheels.
Change to a lower gear in good time before descending a slope in order to take advant-
age of
the en

gine brake.
The trailer is incorporated into the vehicle's
anti-theft alarm system:
● When the vehicle has a factory-fitted anti-
theft al
arm and a towing bracket.
● When the trailer is electrically connected to
the vehic
le via the towing bracket socket.
● When the vehicle electrical device and the
tow
ing bracket are operational.
● When the vehicle is locked and the vehi-
cle's
anti-theft alarm device is activated.
Once the electrical connection is interrupted
with the vehicle trailer locked, the alarm
sounds.
Always switch off the vehicle anti-theft alarm
device before connecting or disconnecting a
trailer. The vehicle anti-theft alarm device
could cause the alarm to sound ››› page 112,
Anti-theft alarm system*.
Engine overheating
In the event that the coolant temperature
gauge needle moves to the right section of
the scale or to the red area, immediately re-
duce speed. If the control lamp  flashes on
the general instrument panel, stop the vehi-
cle and switch off the engine. Wait several
minutes and check the coolant level in the
tank ››› page 208. Please observe the following indications
›››
page 208, Control lamp .
The coolant temperature can be reduced by
switching on the heating. WARNING
● Adjus t

your speed to suit the road and traf-
fic conditions.
● An electrical installation that is connected
incorrectly
or by non-specialised personnel
can prevent the connection of the current to
the trailer and cause faults in the operation of
the electrical system throughout the entire
vehicle, leading to accidents and serious in-
jury.
● All electrical work must be carried out only
by s
pecialised services.
● Never directly connect the trailer electrical
device t
o the electrical sockets of the reverse
driving lights or other sources of electrical
current. CAUTION
● Av oid c

orners, and sudden and sharp brak-
ing.
● Once the trailing arm has been removed,
plac
e the corresponding cover on the hole of
the fastening point. This prevents dirt from
entering the hole – see the trailer system as-
sembly manual. » 185

Water in the fuel filter 1)
If
y
our vehicle has a diesel engine and is
equipped with a fuel filter with a water sepa-
rator, the instrument panel may display the
following warning:  Water in the
fuel filter. If this is the case, take the
vehicle to a specialised workshop so that
they can drain the fuel filter. CAUTION
● The v ehic

le is not designed for the use of
FAME fuel (biodiesel). The fuel system would
be damaged if you used biodiesel.
● Do not mix fuel additives, the so-called
“thinners”, petro
l or similar additives with
diesel fuel.
● If poor-quality diesel fuel is used, it may be
neces
sary to drain the fuel filter more fre-
quently than is specified in the Maintenance
Programme. We recommend having this done
by a specialised workshop. If water is allowed
to collect in the filter, this can cause engine
performance problems. Engine compartment

General
notes The engine comes with a special, multi-grade
oil
th

at can be used all year round.
Because the use of high-quality oil is essen-
tial for the correct operation of the engine
and its long useful life, when topping up or
changing oil, use only those oils that comply
with VW standards.
The specifications (VW standards) set out in
the following page should appear on the con-
tainer of the service oil; when the container
displays the specific standards for petrol and
diesel engines together, it means that the oil
can be used for both types of engines.

Checking and refilling levels
– Re
a
d off the coolant level on coolant ex-
pansion tank ››› Fig. 208. When the engine
is cold, the coolant should be between marks B (min.) and
A (max.). When the
en gine i
s

hot, it may be slightly above mark
A (max.).
If the c
oo

lant fluid level in the reservoir is too
low, this will be indicated by the  red warn-
ing lamp illuminating on the general dash
panel ››› page 208, Control lamp . However,
we recommend checking the coolant level di-
rectly in the tank.
Coolant fluid loss
Any loss of coolant normally indicates a leak.
It is not sufficient merely to top up the cool-
ant. The cooling system should be inspected
by an Official Service without delay. CAUTION
● In the event of

a fault that causes the en-
gine to overheat, contact an authorised SEAT
dealer immediately, as this could damage the
engine.
● Anti-freeze that does not correspond to the
correct
specification may particularly affect
corrosion protection considerably.
● Faults caused by corrosion may lead to
cool
ant leaks. Risk of serious engine faults! Topping up the coolant level
–
Switch the ignition off.
– Wait for the engine to cool down.
– Cover the cap on the coolant expansion
tank ›

›› Fig. 208 with a cloth and carefully
unscrew the cap.
– Refill the level of coolant.
– Screw the cap on again until it clicks into
plac

e.
Do not use a different type of additive if the
prescribed anti-freeze additive is not availa-
ble, in the event of an emergency. In this
case, use only water and bring the coolant
concentration back up to the correct level as
soon as possible at an Official Service.
Always top up with unused coolant.
Never fill the coolant tank above mark A (max.)

Fig. 208 Excess coolant is forced
out of the cooling system through the over-
pressure valve in the filler cap of the expan-
sion tank when the engine heats up. WARNING
● The anti-freez e a

dditive and, therefore, the
entire coolant, are a health hazard. Avoid
touching the coolant. Coolant fumes are also
a health hazard. For this reason, always store
the coolant additive in a safe place out of the
reach of children. Risk of poisoning! ●
If s p

lashed into eyes, rinse immediately
with clean water and seek immediate medical
attention.
● Seek immediate medical attention if the
cool
ant is accidentally ingested. CAUTION
If the coolant cannot be topped up under the
giv en c ondition
