el: Odometer and reset
button
The distance covered is displayed in “kilometres” or miles “m”. It is possi-
ble to change the measurement units (kilometres “km”/miles “m”) in the
radio/Easy Connect*. Please refer to the Easy Connect* Instruction Manual
for more details.
Odometer/trip recorder
The odometer shows the total distance covered by the vehicle.
The trip recorder shows the distance that has been travelled since it was
last reset. It is used to measure short trips. The last digit of the trip recorder
indicates distances of 100 metres or tenths of a mile.
The trip recorder can be set to zero by pressing 0.0/SET

⇒  Fig. 40.
Fault display
If there is a fault in the instrument panel, the letters DEF will appear in the
trip recorder display. Have the fault repaired immediately, as far as is possi-
ble. Fuel level
The display
6 ⇒ Fig. 38 only works when the ignition is switched on. When
the display reaches the reserve mark, the lower diode lights up in red and
the control lamp  appears ⇒ page 248. When the fuel level is very low,
the lower diode flashes in red.
The distance to empty fuel level is displayed on the instrument panel 3
⇒ Fig. 38.
The capacity of the fuel tank of your vehicle is given in the Technical data
section ⇒ page 323.
In natural gas engines
The yellow warning lamp
 lights up when both fuel types (petrol and natu-
ral gas) have reached reserve level.
The green control lamp  comes on when the vehicle is working with natural
gas.
The green control lamp  switches off when the natural gas is exhausted.
The engine changes to operate with petrol.
Thing to note: If the vehicle is left parked for a long time immediately after
refuelling, the natural gas level indicator may not accurately indicate the
same level shown after refuelling when the vehicle is started up again. This
is not due to a leak in the system, but to a drop in pressure in the gas tank
for technical reasons after a cooling phase immediately after refuelling.
CAUTION
Never run the fuel tank completely dry. An irregular fuel supply could cause
misfiring. In this way the unburned fuel can reach the exhaust system,
which could cause the catalytic converter to overheat resulting in damage. 

68Instruments and warning/control lamps
Coolant temperature gauge
For vehicles with no coolant temperature gauge, a control lamp appears for
high coolant temperatures  ⇒ page 257. Take into account the ⇒ .
The coolant temperature gauge 2
⇒ Fig. 38 only works when the ignition is
switched on. In order to avoid engine damage, please read the following
notes for the different temperature ranges.
Engine cold
If only the diodes in the lower part of the scale light up, this indicates that
the engine has not yet reached operating temperature. Avoid high revs and
heavy acceleration and do not make the engine work hard.
Normal temperature
If in normal operations, the diodes light up until the central zone, it means
that the engine has reached operating temperature. At high outside temper-
atures and when making the engine work hard, the diodes may continue
lighting up and reach the upper zone. This is no cause for concern, provided
the control lamp  does not light up on the instrument panel digital dis-
play.
Heat range
When the diodes light up in the upper area of the display and the control
lamp appears  on the instrument panel display, the coolant temperature
is excessive ⇒ page 257.
CAUTION
● To ensure a long useful life for the engine, avoid high revs, driving at
high speed and making the engine work hard for approx. the first 15 mi-
nutes when the engine is cold. The phase until the engine is warm also de-
pends on the outside temperature. If necessary, use the engine oil tempera-
ture* as a guide ⇒ page 77
● Additional lights and other accessories in front of the air inlet reduce the
cooling effect of the coolant. At high outside temperatures and high engine
loads, there is a risk of the engine overheating.
● The front spoiler also ensures proper distribution of the cooling air when
the vehicle is moving. If the spoiler is damaged this can reduce the cooling
effect, which could cause the engine to overheat. Seek specialist assis-
tance. 

Introduction
Additional information and warnings:
● Changing wheels round
● Heating, ventilation, cooling
● Caring for and cleaning the vehicle exterior
WARNING
If the water from the windscreen washer does not contain enough anti-
freeze, it may freeze on the windscreen and rear window, reducing for-
ward and rear visibility.
● In winter, ensure the windscreen washer contains enough anti-freeze.
● In cold conditions, you should not use the wash/wipe system unless
you have warmed the windscreen with the ventilation system. The anti-
freeze could freeze on the windscreen and reduce visibility.
WARNING
Worn or dirty wiper blades reduce visibility and increase the risk of acci-
dent and serious injury.
● Always replace damaged or worn blades or blades which do not clean
the windscreen correctly.
CAUTION
In icy conditions, always check that the wiper blades are not frozen to the
glass before using the wipers. In cold weather, it may help to leave the vehi-
cle parked with the wipers in service position ⇒ page 122. Control lamp

Several warning and control lamps should light up for a few seconds when
the ignition is switched on, signalling that the function is being verified.
They will switch off after a few seconds.
CAUTION
Failure to heed the control lamps and text messages when they appear may
result in faults in the vehicle. 

Introduction
Viewing Climatronic information
On the screen of Climatronic control unit and on the screen of the factory-
fitted Easy Connect system, the theoretical values of the temperature zones
are shown.
The unit of temperature measurement can be changed in the Easy Connect
system.
Dust and pollen filter
The dust and pollen filter with its activated charcoal cartridge serves as a
barrier against impurities in the air taken into the vehicle interior.
The dust and pollen filter must be changed regularly so that air conditioner
performance is not adversely affected.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, the filter must be changed more frequently than sta-
ted in the Service Schedule.
Additional information and warnings:
● Easy Connect system
● Seat functions
● Windscreen wipers and washers
● Caring for and cleaning the vehicle exterior
WARNING
Reduced visibility through the windows increases the risk of serious acci-
dents.
● Always ensure that all windows are free of ice and snow, and that
they are not fogged, so as to maintain good visibility of everything out-
side.
● The maximum heat output required to defrost windows as quickly as
possible is only available when the engine has reached its normal run-
ning temperature. Only drive when you have good visibility.
● Always ensure that you use the heating system, fresh air system, air
conditioner and the heated rear window to maintain good visibility to the
outside.
● Never leave the air recirculation on for a long period of time. If the
cooling system is switched off and air recirculation mode switched on,
the windows can mist over very quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is not required.
WARNING
Stuffy or used air will increase fatigue and reduce driver concentration
possibly resulting in a serious accident.
● Never leave the fresh air fan turned off or use the air recirculation for
long periods of time; the air in the vehicle interior will not be refreshed. 

154Air conditioning
CAUTION
● Switch the air conditioner off if you think it may be broken. This will
avoid additional damage. Have the air conditioner checked by a specialised
workshop.
● Repairs to the air conditioner require specialist knowledge and special
tools. SEAT recommends visiting a SEAT Official Service.
Note
● When the cooling system is turned off, air coming from the outside will
not be dried. To prevent fogging of the windows, SEAT recommends leaving
the cooling system (compressor) turned on. To do this, press the button 
.
The button lamp should light up.
● The maximum heat output required to defrost windows as quickly as
possible is only available when the engine has reached its normal running
temperature.
● 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. Air conditioner controls
