Cockpit
To do this, drive about 15 minutes in fourth or fifth gear (automatic gear-
box: S gear range) at a speed of 60 km/h (37 mph), with the engine running
at approximately 2000 rpm. In this way, the pollen build up in the filter is
burned. When cleaning is successful, the lamp turns off.
If the lamp  does not turn off, or the three lamps turn on (particulate filter
, emission control system fault  and glow plugs ), take the vehicle to
a specialised workshop to repair the fault.
WARNING
● Always drive according to the road weather conditions, the terrain
and traffic. Driving recommendations should never lead to illegal ma-
noeuvres in surrounding traffic.
● The diesel engine particulate filter may reach extremely high temper-
atures; it should not enter into contact with flammable materials under-
neath the vehicle. Otherwise there is a risk of fire.

Anti-lock brake system (ABS)* 
A control lamp monitors the ABS.
The control lamp  should light up for a few seconds when the ignition is
switched on. It goes out again after the system has run through an automat-
ic test sequence.
There is a fault in the ABS if:
● The control lamp  does not light up when the ignition is switched on.
● The control lamp does not go out again after a few seconds.
● The control lamp lights up when the vehicle is moving.
The vehicle can still be braked in the normal way, without the ABS function.
Take the vehicle to a specialised workshop as soon as possible. For further
information on the ABS go to ⇒ page 196. If a fault occurs in the ABS, the ESC* control lamp will also light up.
Brake system fault
If the ABS warning lamp
 lights up together with the brake warning lamp
 , this indicates not only a fault in the ABS function, but also a possible
fault in the brake system ⇒ 
.
WARNING
● Before opening the bonnet, read and observe the warnings on
⇒ page 235, Working in the engine compartment.
● If the brake system warning lamp  should light up together with the
ABS warning lamp , stop the vehicle immediately and check the brake
fluid level in the reservoir ⇒ page 249, Brake fluid. If the brake fluid lev-
el has dropped below the “MIN” mark you must not drive on. Risk of acci-
dent. Obtain technical assistance.
● If the brake fluid level is correct, the fault in the brake system may
have been caused by a failure of the ABS system. This could cause the
rear wheels to lock quickly when you brake. This could cause the rear to
break away. Risk of skidding. Stop the vehicle and seek technical assis-
tance.

Washer fluid* 
This warning lamp lights up to indicate that the windscreen
washer level is too low. This serves as a reminder to fill up the reservoir at the earliest opportunity

WARNING
● Before opening the bonnet, read and observe the warnings on
⇒ page 235.
● If the brake warning lamp does not go out, or if it lights up when driv-
ing, the brake fluid level ⇒ page 249, Brake fluid in the reservoir is too
low. Risk of accident. Stop the vehicle and do not drive on. Obtain techni-
cal assistance.
● If the brake warning lamp  lights up together with the ABS warning
lamp , the control function of the ABS could be out of action. This could
cause the rear wheels to lock quickly when you brake. This could cause
the rear to break away. Risk of skidding. Stop the vehicle and seek tech-
nical assistance.

Handbrake 
This lamp lights up when the handbrake is applied. If you drive faster than 6 km/h (4 mph) with the handbrake on, the following
message will appear on the instrument panel display 1)
: HANDBRAKE ON. You
will also hear an acoustic warning signal ⇒ page 188.
Bulb defect* 
The warning lamp lights up when a bulb in the vehicle's ex-
terior lighting is defective.
The warning lamp  lights up when a bulb in the vehicle's exterior lighting
(e.g. left-hand main beam) is defective. The instrument panel displays the following message
1)
: LEFT FULL BEAM
FAULTY. 
Engine oil pressure 
If this warning lamp is red it indicates that the engine oil
pressure is too low.
If this warning symbol starts to flash, and is accompanied by three audible
warnings, switch off the engine and check the oil level. If necessary, add
more oil ⇒ page 238.
The instrument panel displays the following message 1)
: STOP ENGINE OIL
PRESSURE INSTRUCTION MANUAL .
If the symbol flashes although the oil level is correct, do not drive on. Do
not even run the engine at idle speed! Obtain technical assistance.
Checking the oil level 
If the warning lamp is yellow  the engine oil level should be checked as
soon as possible. Top up the oil ⇒ page 241 at the next opportunity.
Oil level sensor faulty* 
If the  yellow warning lamp flashes, take the vehicle to a specialised
workshop to have the oil level sensor checked. Until then it is advisable to
check the oil level every time you refuel. 

Cruise speed (Cruise control)* 
The warning lamp comes on when the cruise control system
is switched on.
The warning lamp  lights up when the cruise control system is switched
on. For further information on the cruise control system, see ⇒ page 193.
Indicator for open doors or rear lid* 
This warning lamp lights up if one of the doors or the rear
lid is open. The warning light  should go off when all the doors are closed correctly.
The system also works when the ignition is switched off. It should go off ap-
prox. 15 seconds after the vehicle is locked. 
Electromechanical steering* 
For vehicles with power steering, the level of steering assistance depends
on the vehicle's speed and on the steering angle.
The control lamp should light up for a few seconds when the ignition is
switched on. It should go out once the engine is started.
If the battery is disconnected, the indicator remains lit, even with the en-
gine running. The warning light only goes off after a distance of approx. 50
m. There is a fault in the electromechanical steering system if the lamp does
not go out or lights up whilst the vehicle is in motion. The warning lamp
may appear in two different colours to indicate faults. If it lights yellow, this
indicates a minor fault. If it lights red, seek assistance from a specialised
workshop immediately, as the steering assistance is not working; in this
case you should not keep driving. Stop the vehicle and seek technical assis-
tance. The power steering does not work if the battery is flat or if the engine
is off (for example, for towing). You should take into account that you will
need considerably more power than normal to steer the vehicle if the power
steering is not working correctly or at all.
For those vehicles fitted with ESC*, the “Steering manoeuvre recommenda-
tion” function is included. See
⇒ page 198. 
Emission control system* 
This warning lamp monitors the exhaust system.
Control lamp  flashes:
When there is misfiring that can damage the catalytic converter. Reduce
speed and drive carefully to the nearest specialised workshop to have the
engine checked.
The instrument panel displays the following message 1)
: EXHAUST GAS SEE
WORKSHOP.
Control lamp  is lit:
If a fault has developed during driving which has reduced the quality of the
exhaust gas (e.g. lambda probe fault). Reduce speed and drive carefully to
the nearest specialised workshop to have the engine checked.
The following message is shown in the instrument panel display: EXHAUST
GAS SEE WORKSHOP . 

Electronic Stability Control (ESC)*  / 
There are two control lamps for the electronic stability con-
trol. The  lamp provides information concerning the func-
tion and the  provides information on the disconnection
status
Both lamps come on together when the ignition is switched on and should
go out after approx. 2 seconds, which is how long the function check lasts.
This programme includes the ABS, EDL and ASR. This also includes the
brake assistance system (BAS), automatic cleaning of the brake discs and
the trailer stability programme (TSP).
The warning lamp  has the following functions:
● It flashes whilst driving when the ASR/ESC is activated.
● It will light up continuously if there is a fault in the ESC.
● As the ESC operates in conjunction with the ABS, it will also light up if a
fault should occur in the ABS.
If the ESC control lamp  lights up and stays on after the engine is started,
this may mean that the control system has temporarily switched off the ESC.
In this case the ESC can be reactivated by switching the ignition off and
then on again. If the control lamp goes out, this means the system is fully
functional.
The  lamp provides information about the disconnection status of the
system:
● It stays lit when the ASR is disconnected when pressing the  switch.Differential lock fault (EDL)*The EDL operates along with the ABS in vehicles equipped
with the Electronic Stability Control (ESC)*
A malfunction in the EDL is indicated by the ABS control lamp . Take the
vehicle to a specialised workshop as soon as possible. For further informa-
tion on the EDL see ⇒ page 199, Electronic differential lock (EDL)*. 
Traction control system (ASR)*  / 
The traction control system prevents the driven wheels from
spinning when the vehicle is accelerating
There are two warning lamps for the traction control system:  and . Both
lamps come on together when the ignition is switched on and should go out
after approx. 2 seconds, which is how long the function check lasts.
The  lamp has the following function:
● It flashes when the ASR is working if the vehicle is moving.
If the system is deactivated or if it has any fault, the warning lamp will re-
main lit. The warning lamp will also light up if a fault should occur in the
ABS because the ASR operates in conjunction with the ABS. For further in-
formation, see ⇒  page 196, Brakes.
The  lamp provides information about the disconnection status of the
system:
● It stays lit when the ASR is disconnected when pressing the ASR OFF
switch.
By pressing it again, the ASR function is reactivated and the warning lamp
switched off. 

Air conditioning
● The engine is not running.
● The blower is switched off.
● The outside temperature is lower than approximately +3 °C (+37 °F).
● The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high. ●
The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air conditioner checked by a speci-
alised workshop. 
Air recirculation mode 
Air recirculation mode prevents fumes or unpleasant smells from coming from the outside.
Fig. 132 On the dash panel: Climatic controls
Air recirculation mode ⇒ Fig. 132 
prevents strong odours in the outside
air from entering the vehicle interior, for example when passing through a
tunnel or in queuing traffic.
With low temperatures outside, the air recirculation increases the effective-
ness of the heating system by warming the air inside the vehicle rather than
the cold air from outside. With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle
rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution
towards the windscreen mode is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be connec-
ted.

Air conditioning
With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle
rather than the ambient air.

this remains active. When the recirculation mode is on, if the air distribution
towards the windscreen mode is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be connec-
ted.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning system 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).

General notes
Pollution filter
The pollution filter (a combined particulate filter and active carbon filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the air conditioner to work with maximum efficiency, the pollution filter
must be replaced at the intervals specified in the Service Plan.
If the filter loses efficiency prematurely due to use in areas reaching very
high pollution levels, the pollen filter must be changed more frequently
than stated in the Service Schedule.
Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves comfort for the vehicle occupants and prevents misting of the windows
when the ambient air humidity is high.
If the air conditioning system cannot be switched on this may be caused by
the following reasons:
●
The engine is not running.
● The AC
button is disconnected.
● The outside temperature is lower than approximately +3 °C (+37 °F).
● The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air conditioner checked by a speci-
alised workshop.
CAUTION
● If you suspect that the air conditioner is damaged, switch it off with but-
ton AC
to prevent further damage and have it checked by a specialised
workshop.
● Repairs to the air conditioner require specialist knowledge and special
tools. Therefore, we recommend you to take the vehicle to a specialised
workshop.
Note
● If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and so forming a pud-
dle underneath the vehicle. This is completely normal and there is no need
to suspect a leak.
● Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling are not impaired, and to prevent the
windows from misting over.
● The air from the vents flows through the vehicle interior and is extracted
by slots designed for this purpose. Therefore, do not cover these slots with
items of clothing or other objects. 

Driving
If the engine does not start immediately, switch the starter off after 10 sec-
onds and try again after half a minute. If the engine still does not start, the
fuel pump fuse should be checked ⇒ page 272, Fuses.
WARNING
● Never start or run the engine in unventilated or closed rooms. The ex-
haust gases contain carbon monoxide, an odourless and colourless poi-
sonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also result in death.
● Never leave the vehicle unattended if the engine is running.
● Never use “cold start sprays”, they could explode or cause the engine
to run at high revs. Risk of injury.
CAUTION
● When the engine is cold, 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 metres to start
the engine. Unburnt fuel could enter the catalytic converter and damage it.
● Before attempting to push-start or tow a vehicle in order to start it, you
should first try to start it using the battery of another vehicle. Note and fol-
low the instructions in ⇒ page 287, Jump-starting.
For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle station-
ary. Start off immediately, driving gently. This helps the engine reach oper-
ating temperature faster and reduces emissions. Starting diesel engines
The engine can only be started using a genuine SEAT key
with its correct code.
– Move the gearbox lever to the neutral position and depress the
clutch pedal thoroughly and hold it in this position for the start-
er to turn the engine on.
– Turn the ignition key to the starting position.
– Turn the ignition key to position ⇒ Fig. 140 1
. The warning
lamp  will light for engine pre-heating.
– When the lamp turns off, turn the ignition key to position 2
to
start the engine. Do not press the accelerator.
– Let go of the ignition key as soon as the engine starts, the start-
er motor must not be allowed to run on with the engine.
When starting a very cold engine, it may be a little noisy for the first few sec-
onds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.
If there are problems starting the engine, see the ⇒ page 287.
Glow plug system for the diesel engine
To avoid unnecessary discharging of the battery, do not use any other major
electrical equipment while the glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒ page 82 goes
out.
Starting the diesel engine after the fuel tank has been completely run dry
If the fuel tank has been completely run dry, it may take longer than normal
(up to one minute) to start a diesel engine after refuelling. This is because
the fuel system must eliminate air first. 
