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
6)
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.
Ø mph - Average speed
The average speed will be shown 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 whilst the vehicle is in motion.
Miles - Distance travelled
The display shows the distance travelled since the ignition was switched on.
The maximum display value in both memories is 9999 miles. The memory will
automatically be deleted once this value has been reached.
 Miles - Fuel range
The fuel range is calculated using the fi gures 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/100km - Average fuel consumption
The average fuel consumption will be shown ⇒page 62, 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
whilst the vehicle is in motion. The am ount of fuel used will not be shown. litres/100km or litres/hr - Current 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 180.
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.
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-

The warning lamp lights up if the coolant temperature is too
high or if the coolant level is too low.There is a fault if:•
The warning symbol does not go out again after a few seconds.
•
The warning lamp lights up or flashes while the vehicle is moving, while
three acoustic warning signals ⇒ are emitted.
This means that either the coolant level is too low or the coolant temperature
is too high.
Coolant temperature too high
The following text is displayed in the instrument panel display

COOLANT! INSTRUCTIONS MANUAL .
First look at the coolant temperature gauge. The coolant temperature is too
high if the needle is over the warning area on the dial. Stop the vehicle,
switch off the engine and wait for it to cool down. Check the coolant level.
If the coolant level is correct, the over heating may be caused by a malfunction
of the radiator fan. Check the radiator fan fuse and have it replaced if neces-
sary ⇒page 232.
If the warning lamp lights up again after driving on for a short distance, stop
the vehicle and switch off the engine . Contact an Authorised Service Centre
or a qualified workshop.

If the symbol flashes although the oil level is correct, do not drive on. The
engine must not even run at idle speed. Obtain technical assistance.
Anti-lock brake system (ABS)


A warning lamp system monitors the ABS.
The warning 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 automatic
test sequence.
There is a fault in the ABS if:
•
The warning lamp
 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 (except that the ABS control
function will not function). Please take the vehicle to a qualified workshop as
soon as possible. For further information on the ABS see the ⇒page 169.
If a fault occurs in the ABS, the ESP* warning 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 198.
•
If the brake 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 211, “Brake fluid”. If the fluid level has
dropped below the “MIN” mark you must not drive on. Risk of accident.
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. Drive carefully to the nearest qualified workshop
and have the fault corrected.
Differential lock fault (EDL)*
EDL operates along with the ABS in vehicles equipped with an
Electronic Stabilisation Program (ESP)*A malfunction in the EDL is indicated by the ABS warning lamp

This warning lamp monitors th e engine management system
for petrol engines.
The warning lamp
 (Electronic Power Control) lights up when the ignition
is switched on to show that the lamp is working properly. It should go out
when the engine has started running.
If a fault develops in the electronic engine management system while you are
driving, this warning lamp will light up. Take the vehicle to an Authorised
Service Centre as soon as possible and have the engine checked.
Glow plug system / Engine fault

Centre as soon as possible and have the engine checked.
Emission control system*


This warning lamp monitors 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 following text is displayed in the instrument panel display

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 text is displayed in the instrument panel display: EXHAUST
FUMES GO TO WORKSHOP! .
Electronic stabilisation programme (ESP)*

This warning lamp monitors the electronic stabilisation
program.
This program includes the ABS, EDL and TCS.
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 light up continuously if the ESP is switched off.
•
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
functional.
Operating the foot brake

The footbrake must be depressed when this warning lamp lights up. This is
necessary when the automatic gearbox* selector lever is moved out of the
positions P or N.Power steering system*

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 when the engine has started running.
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 electromechanica l steering system if the lamp does not
go out or light up, wh ils
t 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.
Brake pad wear indicator*

As the brake pad wear indicator only monitors the front brake pads, it is advis-
able to have the rear brake pads inspected at the same time.
The information text displayed in the instrument panel display is
16): CHECK
BRAKE PADS .
WARNING
Have the brake pads inspected immediately by a qualified dealership if the
warning display
 lights up.
Indicator for open doors or tailgate

This indicator lights if one of th e doors or the tailgate 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
about 15 seconds after the vehicle is locked.

– 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.After starting a very hot engine, you may need to press the accelerator briefly.
When starting from cold, the engine ma y 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 the engine does not start immediately, switch off the starter after about
10 seconds and try again after about half a minute. If the engine still does not
start, the fuel pump fuse should be checked ⇒page 232, “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 for more than approximately
50 metres to start the engine. Fuel could enter the catalytic converter and
damage it.
•
Before attempting to push-start or tow a vehicle to start it, you should first
try to start it using the battery of another vehicle. Note and follow the instruc-
tions ⇒page 248, “Jump-starting”.
For the sake of the environment
Do not warm up the engine by running the 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
the correct code.– Move the gear lever to the ne utral position and depress the
clutch pedal fully and hold it in this position, the starter will then
only have to turn the engine.
– Turn the ignition key to the starting position.
– Turn the ignition key to position ⇒page 152, fig. 115 . The
indication lamp

will light for engine pre-heating.
– When the warning lamp goes out, 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 from cold, the engine 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 248.

Tips and Maintenance
Te c h n i c a l D a t a
Think ahead when drivingA vehicle uses most fuel when accelera ting. If you think ahead when driving,
you will need to brake less and thus accelerate less. Wherever possible, let
the vehicle roll slowly to a stop, for instance when you can see that the next
traffic lights are red.Regular servicingBy taking your car to an Authorised Service Centre for regular servicing you
can establish a basis for good fuel economy before you start driving. A well-
serviced engine gives you the benefit of improved fuel efficiency as well as
maximum reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Check the oil level every time you fill the tank ⇒page 203. Oil consumption
depends to a great extent on the engine load and engine speed. Depending
on your personal driving style, oil consumption can be up to 1 litre per 1,000
km.
Avoid short journeysThe engine and catalytic converter need to reach their proper working
temperature in order to minimise fuel consumption and emissions.
Directly after a cold start, the engine uses about 50-70 litres of fuel per
100 km. This figure then drops to 20 -30 litres per 100 km after about one
kilometre. The engine only reaches its working temperature after about four
kilometres, when fuel consumption will return to a normal level. You should
therefore avoid short journeys.
The ambient temperature has a decisive influence.
The illustration shows the different rates of fuel consumption for the same
distance at both +20°C and -10°C. Your vehicle will use more fuel in winter
than in summer.

tion in litres per 100 km at
