output, which is needed to
defrost the windows quickly, is only available
when the engine has reached its operating
temperature.
Coolant system
When the air conditioning is switched on, the
temperature and the air humidity go down.
This way, if the outside humidity is extreme,
the air conditioning prevents the misting of
the windows and therefore, comfort is im-
proved.
If the air conditioning does not work, this
may be due to the following reasons:
● The engine is stationary.
● The fan blower is switched off.
● The outside temperature is lower than ap-
proxim
ately +3 °C (+37 °F).
● The air conditioning system compressor
has been t
emporarily switched off because of
an increased engine coolant temperature.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air
conditioning chec
ked by a specialised work-
shop. Air recirculation
 Air recirculation prevents unpleasant smells,
e.g. when pa
s

sing through a tunnel or in
queuing traffic, from entering the interior.
If the rotary switch C

thaw position, the recirculation flap will al-
ways be open (button light off).
If the rotary switch C is switched from any
position t o the th

aw position, recirculation
will be automatically deactivated.

● Pr e

ss button D again and the button's
l amp w
il

l go off, indicating that air recircula-
tion from the outside has been activated. In the thaw position of rotary switch
C , the

In air recirculation mode, no cold air from the
outside ent er

s the vehicle interior. If the air
conditioner is switched off, the windows can
quickly mist over. Therefore, never leave the
air recirculation mode switched on for a long
time (risk of accident). Note
● When engagin g r

everse gear, the air recir-
culation is connected automatically to pre-
vent the entrance of exhaust gases in the ve-
hicle on travelling backwards. The control
lamp on the button  does not light up.
● If the temperature control is turned to the
col de

st setting (blue point) and the A/C but-
ton is on, the
“Air recirculation” function is
automatically activated in order to cool the
vehicle faster using less energy, and its func-
tion control lamp will light up.
● If the function is not deactivated by press-
ing the button, it
will deactivate after approx-
imately 20 minutes. 145

T k

ey with its correct code.
– Move the gearbox lever to the neutral posi-
tion and depress

age 150.
– Let go of the ignition key as soon as the en-
gine starts; the s

tarter motor must not run
on with the engine.
After starting a very hot engine, you may
need to slightly press down the accelerator.
When starting a cold engine, it may be a little
noisy for the first few seconds until oil pres-
sure has built up in the hydraulic valve com-
pensators. This is quite normal, and no cause
for concern.
If the engine does not start immediately,
switch the starter off after 10 seconds and try
again after half a minute. If the engine still
does not start, the fuel pump fuse should be
checked ›››
page 81, Fuses. WARNING
● Never st ar

t or run the engine in unventila-
ted or closed rooms. The exhaust gases con-
tain carbon monoxide, an odourless and col-
ourless poisonous gas. Risk of fatal acci-
dents. Carbon monoxide can cause loss of
consciousness and result in death.
● Never leave the vehicle unattended if the
engine is ru
nning.
● Never use “cold start sprays”, they could
explode or cau
se the engine to run at high
revs. Risk of injury. CAUTION
● When the engine is c

old, you should avoid
high engine speeds, driving at full throttle
and over-loading the engine. Risk of engine
damage.
● The vehicle should not be pushed or towed
more than 50 metre
s to start the engine. Un-
burnt fuel could enter the catalytic converter
and damage it.
● Before attempting to push-start or tow a ve-
hicle in order t
o start it, you should first try to
start it using the battery of another vehicle.
Please observe and follow the notes on the

Operation
At speeds of up to approximately 80 km/h
(50 mph), it i
s ab
le to balance out differences
in the speed of the driven wheels of approxi-
mately 100 rpm/min caused by a partially
slippery road surface. It does this by braking
the wheel which has lost traction and distrib-
uting more driving force to the other driven
wheel via the differential.
To prevent the disc brake of the braking
wheel from overheating, the EDL cuts out au-
tomatically if subjected to excessive loads.
The vehicle will continue to function normally
without EDL. For this reason, the driver is not
informed that the EDL has been switched off.
The EDL will switch on again automatically
when the brake has cooled down.
Control lamp
A malfunction in the EDL is indicated by the
ABS control lamp  ››› page 158. Take the
vehicle to a specialised workshop as soon as
possible. WARNING
● When accel er

ating on a slippery surface,
for example on ice and snow, press the accel-
erator carefully. Despite EDL, the driven
wheels may start to spin. This could impair
the vehicle's stability.
● Always adapt your driving style to suit road
conditions and the tr
affic situation. Do not let
the extra safety afforded by EDL tempt you in- to taking any risks when driving, this can
cause ac
c

idents. CAUTION
Modifications to the vehicle (e.g. to the en-
gine, the br ake sys

tem, running gear or any
components affecting the wheels and tyres)
could affect the efficiency of the EDL
››› page 190. Hydraulic Brake Assist (HBA)*
The function (Hydraulic Brake Assist HBA) is
on
ly
inc luded in

vehicles with ESC.
In an emergency, most drivers brake in time,
but not with maximum force. This results in
unnecessarily long braking distances.
This is when the brake assist system comes
into action. When pressing the brake pedal
rapidly, the assistant interprets it as an emer-
gency. It very quickly builds up the full brake
pressure so that the ABS can be activated
more quickly and efficiently, thus reducing
braking distance.
Do not reduce the pressure on the brake ped-
al, since the brake assist system switches off
automatically as soon as you release the
brake. Automatic hazard warning lights activation
The brake lights fl

ash automatically to indi-
cate that the vehicle is braking suddenly or in
an emergency situation. If the emergency
braking continues until the vehicle comes to
a standstill, the hazard warning lights will
then come on and the brake lights will re-
main on permanently from that moment. The
warning lights will automatically switch off
when the vehicle begins to move again or
when the "warning" light button is pressed. WARNING
● The risk of ac

cident is higher if you drive
too fast, if you do not keep your distance from
the vehicle in front, and when the road sur-
face is slippery or wet. The increased acci-
dent risk cannot be reduced by the brake as-
sist system.
● The brake assist system cannot defy the
laws
of physics. Slippery and wet roads are
dangerous even with the brake assist system!
Therefore, it is essential that you adjust your
speed to suit the road and traffic conditions.
Do not let the extra safety features tempt you
into taking any risks when driving. Anti-lock brake system (ABS)
The anti-lock brake (ABS) system prevents
the wheel
s
fr om loc

king during braking and
is an important part of the vehicle's active
safety system.

Operation
Catalytic converter To maintain the useful life of the catalytic
conv
er
ter
– Use only unleaded petrol with petrol en-
gines, as l

ead damages the catalytic con-
verter.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish
with too much en

gine oil ››› page 206, Top-
ping up engine oil.
– Never tow the vehicle to start it, use jump
lea d

s if necessary ›››
 page 52.
If you notice misfiring, uneven running or
loss of power when the vehicle is moving, re-
duce speed immediately and have the vehi-
cle inspected at the nearest specialised
workshop. In general, the exhaust warning
lamp will light up when any of the described
symptoms occur ›››
page 100. If this hap-
pens, unburnt fuel can enter the exhaust sys-
tem and escape into the environment. The
catalytic converter can also be damaged by
overheating. CAUTION
Never run the fuel tank completely dry be-
cause the irr e

gularity of the fuel supply may
cause ignition problems. This allows unburnt
fuel to enter the exhaust system, which could
cause overheating and damage the catalytic
converter. For the sake of the environment
Even when the emission control system is
workin g per

fectly, there may be a smell of
sulphur from the exhaust gas under some
conditions. This depends on the sulphur con-
tent of the fuel used. Quite often the problem
can be solved by changing to another brand
of fuel. Diesel engine particulate filter*
Fig. 173

e Programme. Your vehicle is fitted with a DPF (Diesel Partic-
u
l
at e Fi

lter) if the vehicle data sticker (back
cover of the “Maintenance Programme”) lists
the code PR 7GG ››› Fig. 173.
The diesel engine particulate filter eliminates
most of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. If this is not possible (for ex- ample, multiple short trips) the filter will be
obstruct

ed by soot and  the diesel engine
particulate filter warning lamp will light up.
This does not represent a fault, it is a warning
that indicates that the filter has not been
able to regenerate automatically and that you
must perform a cleaning cycle, as indicated
below.
Accumulation of soot in the diesel engine
particulate filter* 
If the control lamp  lights up you should
help the filter clean itself by driving in the ap-
propriate manner.
To do this, drive about 15 minutes in fourth
or fifth gear (automatic gearbox: S gear
range) at a minimum speed of 60 km/h
(37 mph), with the engine running at approxi-
mately 2,000 rpm. In this way, the soot build
up in the filter is burned. When cleaning is
successful, the control lamp turns off.
If the lamp  does not turn off, or the three
lamps turn on (particulate filter , fault in
the emission control system  and glow
plugs ), drive the vehicle to a specialised
workshop and have the fault repaired at the
earliest opportunity. WARNING
Always drive according to the road weather
conditions, the t err

ain and traffic. Driving rec-
ommendations should never lead to illegal
manoeuvres in surrounding traffic. 170

Driving
CAUTION
● Your v ehic
le is not designed to use biodie-
sel fuel. Never, under any circumstances re-
fuel with biodiesel. The use of biodiesel fuel
could damage the engine and the fuel sys-
tem. The addition of biodiesel to diesel by
the diesel producer in accordance with stand-
ard EN 590 is authorised and will not cause
damage to the engine or the fuel system.
● Using diesel fuel with a high sulphur con-
tent ma
y significantly reduce the useful life of
the diesel particulate filter. Your Technical
Service will be able to tell you which coun-
tries have diesel with a high sulphur content. Engine management* 
This warning lamp monitors the engine man-
ag
ement
sys

tem for petrol engines.
The warning lamp  (Electronic Power Con-
trol) lights up when the ignition is switched
on while system operation is being verified. It
should go out once the engine is started.
If there is a fault in the electronic engine
management system while you are driving,
this warning lamp will light up. Take the vehi-
cle to a specialised workshop as soon as
possible and have the engine checked. Emission control system*  Control lamp
 flashes:
When ther

Driving abro
ad To drive abroad, the following must be taken
into con
s

ideration:
● For vehicles fitted with a catalytic converter
ensure th
at unleaded petrol is available for
the journey. See the chapter “Refuelling”. Au-
tomobile organisations will have information
about service station networks selling unlea-
ded fuel.
● In some countries, it is possible that your
car model i s

not sold, and therefore some
spare parts are not available or the technical
services may only be able to carry out limited
repairs.
SEAT importers and distributors will gladly
provide information about the technical prep-
aration that your vehicle requires and also
about necessary maintenance and repair
possibilities.
Adhesive strips for headlights
In countries where vehicles drive on the other
side of the road to your home country, the
