62 Km - Fuel range
The fuel range is calculated using the fig ures for tank content and current fuel
consumption. It shows how far the vehicle can travel using the same condi-
tions as a reference.
Ø litre/100 km - Average fuel consumption
The average fuel consumption will be shown ⇒page 61, fig. 41 after a
distance of approximately 100 metres has been travelled. Dashes will appear
in the display until that time. The display will be updated every 5 seconds
while the vehicle is in motion. The amount of fuel used will not be shown.
ltr/100 km or ltr/hr - Cu rrent fuel consumption
The display will show the current fuel consumption in litre/km whilst the
vehicle is in motion or in litre/hour when the vehicle is in a stationary position
with the engine running.
Using this display you can see how your driving style affects fuel consump-
tion ⇒page 184.
Ambient temperature display
The measurement margin extends from -45°C to +58°C. At temperatures
lower than +4°C, an “ice crystal symbol” is displayed and a “warning” sounds
if the vehicle is moving at more than 20 km/h (ice warning). This symbol will
flash for about 10 seconds and remains lit until the exterior temperature rises
above +4°C or 6°C if it was already lit.
Set speed indicator
When driving at the required speed, enter the speed indicator mode and
press the button (Reset), the display remembers the indicated speed. If
the indicated speed is exceeded, a warning text is displayed on the screen
5)
and a warning signal sounds.
This may be deactivated by pressing the button (Reset). The speed may be altered using the rocker switch in steps of 5 km/h
within 5 seconds of the initial memory value.
WARNING
There could be black ice on the road surface even if the “snowflake symbol”
is not shown. You should, for this
reason, not rely exclusively on this
display - Risk of accident!
Note
When the vehicle is stationary or travelling at very low speeds, the tempera-
ture displayed may be slightly higher than the actual ambient temperature as
a result of the heat radiated from the engine.Warning or information text in the display*
Faults are shown in the display with warning lamps and
warning/information reports.The system runs a check on certain components and functions when the igni-
tion is switched on and while the vehicle is moving. Functional faults are indi-
cated by symbols with warnings and in formation texts in the display. An
audible warning is given in certain cases.
Warning symbols
There are red warning symbols (priority 1) and yellow warning symbols
(priority 2)
Information text
In addition to warning mess ages given on a fault, you will receive information
in the display on procedures or will be asked to carry out certain tasks.
5)Depending on the model version, the message on the screen may vary and may be
represented by flashing of the speed indication or by a speed message.

appropriate manner.
To do this, drive about 15 minutes in 4th or 5th gear (automatic gearbox: S
gear range) at a speed of 60 km/h, with the engine running at approximately
2000 rpm. In this way, the pollen buil d up in the filter is burned. When
cleaning is successful, the indicator turns off.
If the indicator
 is not deactivated, bring the vehicle to a specialised work-
shop 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. Failure to comply could result in fire.

Practical tips
Te c h n i c a l D a t a
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 of
f after a distance of approx. 50 m.
There is a fault in the electromechanica l steering system if the lamp does not
go out or lights up whilst the vehicle is in motion. The indicator may appear
in two different colours to indicate faults. If it lights yellow, this indicates a
minor fault. If it lights red, seek wo rkshop assistance immediately, if no
assistance is available stop 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
steering assistance is reduced or has failed completely.
For those vehicles fitted with ESP* the function “Recommended steering
manoeuvre” is included. See ⇒page 177.
Emission control system*


This warning lamp monito rs the exhaust system.
Warning lamp
 flashes:
When there is misfiring that can damage the catalytic converter. Reduce
speed and drive carefully to the nearest qualified workshop to have the
engine checked.
The instrument panel displa ys the following message
16): EXHAUST GAS SEE
WORKSHOP . Warning 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 qualified workshop to have the engine checked.
The following information text displayed in the instrument panel display:
EXHAUST GAS SEE WORKSHOP .
Electronic stabilisation programme (ESP)*

This warning lamp monitors the electronic stabilisation
programme.
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 will light for about 2 seconds when the ignition is switched on while a
test of the function is carried out.
•
It flashes when the 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.
If the ESP button is activated, the TCS function deactivates and the warning
lamp flashes.

Driving
158If 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 239, “Fuses”.
WARNING
•
Never start or run the engine in un ventilated or closed rooms. The
exhaust fumes contain carbon mono xide, 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 av oid 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 th e 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 batte ry of another vehicle. Note and follow
the instructions ⇒page 253, “Jump-starting”.For the sake of the environment
Do not warm-up the engine by running th e engine with the vehicle stationary.
You should drive off as soon as you start the engine. 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 ne utral 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 156, fig. 118 . The
indication lamp

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 ⇒page 253.
Glow plug system for the diesel engine
To avoid unnecessary discharging of th e battery, do not use any other major
electrical equipment while th e glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒page 76 goes out.
Starting the engine after the fuel tank has been completely run dry
If the fuel tank has been completely ru n 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.
