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 one tenths of a mile.
The trip recorder can be set to zero by pressing 0.0/SET

⇒  Fig. 38.
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. 36 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 207. 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. 36.
The capacity of the fuel tank of your vehicle is given in the Technical data
section ⇒ page 276.
CAUTION
Never run the fuel tank completely dry. An irregular fuel supply could cause
misfiring. In this way the fuel can arrive without burning the exhaust sys-
tem, which could cause the catalytic converter to overheat resulting in dam-
age. 
Coolant temperature gauge
For vehicles with no coolant temperature gauge, a control lamp appears for
high coolant temperatures  ⇒ page 215. Take into account the ⇒ .
The coolant temperature gauge 2
⇒ Fig. 36 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. 

Introduction
With the ignition switched on, it is possible to read the different functions of
the display by scrolling through the menus.
In vehicles with multifunction steering wheel, the multifunction display can
only be operated with the multifunction steering wheel buttons.
The number of menus displayed on the instrument panel will vary according
to the vehicle electronics and equipment.
A specialised workshop will be able to programme or modify additional
functions, according to the vehicle equipment. SEAT recommends visiting a
SEAT Official Service.
Some menu options can only be read when the vehicle is at a standstill.
As long as a priority 1 warning is displayed, it will not be possible to read
the menus. Some warning messages can be confirmed and made to disap-
pear with the windscreen wiper lever button or the multifunction steering
wheel button.

Intelligent technology
If the warning lamp remains on and the driver indication appears, the power
steering could be faulty.
Do not continue driving. Seek specialist assistance.  (in yellow) Steering: System fault! You may continue driving.
If the warning lamp comes on, the steering could react with more difficultly
or more sensitivity than normal. In addition, when driving in a straight line
the steering wheel may be off-centre.
Drive slowly to a specialised workshop and have the fault repaired.  (in yellow) Steering lock: fault! Go to an Official Service
The electronic steering lock is malfunctioning.
Go to a specialised workshop as soon as possible and have the fault re-
paired.
WARNING
Take it immediately to a specialised workshop and have the fault re-
paired: risk of accident!
Note
If a  red or  yellow warning lamp come on briefly, you can continue driv-
ing. Power Management
This system helps to ensure reliable starting
The power management controls the distribution of electri-
cal energy and thus helps to ensure that there is always
enough power available to start the engine.
If a vehicle with a conventional electrical system is left parked for a long
time, the battery will gradually lose its charge because certain electrical
equipment (such as the electronic gearbox lock) continues to draw current
even when the ignition is off. In some cases there may not be enough power
available to start the engine.
Your vehicle is equipped with an intelligent power management system to
control the distribution of electrical energy. This significantly improves relia-
bility when starting the engine, and also prolongs the useful life of the bat-
tery.
The main functions incorporated in the power management system are bat-
tery diagnosis , residual current management and dynamic power manage-
ment.
Battery diagnosis
The battery diagnosis function constantly registers the condition of the bat-
tery. Sensors detect the battery voltage, battery current and battery temper-
ature. This enables the system to calculate the current power level and
charge condition of the battery.
Residual current management
The residual current management reduces power consumption while the ve-
hicle is parked. It controls the supply of power to the various electrical com-
ponents while the ignition is switched off. The system takes the battery di-
agnosis data into consideration. 

Intelligent technology
Information recorded in the control units
Your vehicle is fitted at the factory with a series of electronic control units
responsible for the engine and gearbox management. In addition, the con-
trol units supervise the correct performance of the exhaust gas system and
the airbag systems.
Therefore, while the vehicle is being driven, these electronic control units
are continuously analysing the vehicle data. In the event of faults or devia-
tions from the theoretical values, only this data is stored. Generally, the in-
strument panel warning lamps indicate whether there are any malfunctions.
This data can only be read and analysed using special equipment.
The storing of the data allows specialised workshops to detect and repair
faults. Stored data may include:
● Important data about the engine and gearbox
● Speed
● Direction of travel
● Braking force
● Seat belt check
The vehicle control units never record conversations held by passengers in
the vehicle.
If the control unit records an accident with airbag activation, the system
may automatically send a signal. This will depend on the network operator.
Normally, transmission is only possible in areas with sufficient coverage.
Event Data Recorder
The vehicle is not fitted with an event data recorder.
An event data recorder temporarily stores the vehicle information. There-
fore, in the event of accident, it is possible to obtain detailed information
about how the accident occurred. For example, in vehicles with airbag sys-
tems, data relating to speed of impact, seat belt status, seat positions and airbag activation times may be stored. The volume of data depends on the
manufacturer.
Event data recorders can only be mounted with authorisation from the vehi-
cle owner and, in some countries, they are governed by local legislation.
Reprogramming control units
On the whole, all the data required for the component management is stor-
ed in the control units. The programming of certain convenience functions,
such as the turn signal convenience mode, individual door opening and dis-
play indications can be modified using special equipment at the workshop.
If the convenience functions are reprogrammed, the Instruction Manual in-
formation and descriptions will not coincide with the modified functions.
Therefore, SEAT recommends that any changes are recorded in the “Other
workshop notes section” of the Service Plan.
You can find out about possible reprogramming at your SEAT Official Serv-
ice.
Event recorder
In the footwell on the driver side you will find the diagnostics connection
socket for reading the event recorder. The event recorder stores operating
data and data on the status of the electronic control units. The events re-
corder should only be read and deleted by a SEAT Official Service or special-
ised workshop.
WARNING
The diagnostics connection socket must not be used for private purpo-
ses. Improper use can cause malfunctions: risk of accident!
