Soot accumulation in the diesel engine particulate filter

If the warning lamp
 lights up you should help the filter clean itself by
driving in the appropriate manner.
To do this, drive about 15 minutes in fourth or fifth gear (automatic gearbox:
S gear range) at a speed of 60 km/h, with the engine running at approxi-
mately 2000 rpm. In this way, the pollen build up in the filter is burned. When
cleaning is successful, the indicator turns off.
If the warning lamp  does not turn off, or the three lamps turn on (partic-
ulate filter
, emission control system fault
 and glow plugs
D), 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 manoeuvres
in surrounding traffic.•The diesel engine particulate filter may reach extremely high tempera-
tures; 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)*
J
A warning lamp monitors the ABS.
The indicator lamp
J should light up for a few seconds when the ignition is
switched on. It goes out again after the system has run through an automatic
test sequence.
There is a fault in the ABS if:
•The warning lamp
J does not light up when the ignition is switched on.
•The warning lamp does not go out again after a few seconds•The warning 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 185.
If a fault occurs in the ABS, the ESP* warning lamp will also light up.
Brake system fault
If the ABS warning lamp
J lights up together with the brake warning lamp
H, this indicates not only a fault in the ABS function, but also a possible fault
in the brake system ⇒.

88Indicator for open doors or tailgate*
o
This warning lamp lights up if one of the doors or the tailgate
is open.The warning light
o should go off when all the doors are closed correctly.
The system also works when the ignition is switched off. It should go off
approx. 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 warning 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 engine
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 indi-
cates a minor fault. If it lights red, seek workshop assistance immediately, as
the steering assistance is not working; in this case you should not keep
driving. Stop the vehicle and seek technical assistance. 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 ESP* the function “Recommended steering
manoeuvre” is included. See ⇒page 187.
Emission control system*

This warning lamp monitors the exhaust system.

This programme includes the ABS, EDL and TCS. This also includes the brake
assist system (BAS), automatic cleaning of the brake discs and the trailer
stability programme (TSP).
The warning lamp
 has the following functions:
•It flashes when the TCS/ESP is activated when driving.•It will light up continuously if there is a malfunction in the ESP.•It will also come on if a fault should occur in the ABS because the ESP
operates in conjunction with the ABS.
If the ESP warning lamp
 lights up and stays on after the engine is started,
this may mean that the control system has temporarily switched off the ESP.
In this case the ESP can be reactivated by switching the ignition off and then
on again. If the warning lamp goes out, this means the system is fully func-
tional.
The
l lamp provides information about the disconnection status of the
system:
•It stays lit when the TCS is disconnected after pressing the
l switch.
Differential lock fault (EDL)*
EDL operates along with the ABS in vehicles equipped with an
Electronic Stability Programme (ESP)*A malfunction in the EDL is indicated by the ABS warning lamp
J. Take the
vehicle to a specialised workshop as soon as possible. For further informa-
tion on the EDL see ⇒page 188, “Electronic differential lock (EDL)*”.

Driving
164If 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 254, “Fuses”.
WARNING
•Never start or run the engine in un ventilated or closed rooms. The
exhaust fumes contain carbon monoxide, an odourless and colourless
poisonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also cause 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 follow
the instructions in ⇒page 267, “Jump-starting”.For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle stationary.
Start off immediately, driving gently. This helps the engine reach operating
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 gear lever to the neutral position and depress the
clutch pedal thoroughly and hold it in this position for the starter
to turn the engine on.
– Turn the ignition key to the starting position.
– Turn the ignition key to position ⇒page 162, fig. 117 . The
indicator lamp
D will light for engine pre-heating.
– When the warning lamp turns off, turn the key to position to
start the engine. Do not press the accelerator.
– Let go of the ignition key as soon as the engine starts, the starter 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
seconds 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 267.
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 83 goes out.
Starting the 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 the engine after refuelling with diesel fuel. This is
because the system must eliminate air first.
