Instruments and warning/control lamps
WARNING
Although the outside temperature is above freezing, some roads and
bridges may be frozen.
● At an outside temperature of above +4 °C (+39 °F), even when the
“ice crystal” is not visible, there may still be ice on the road.
● Never rely on the outside temperature indicator!
CAUTION
Failure to heed the control lamps and text messages when they appear may
result in faults in the vehicle.
Note
● Different versions of the instrument panel are available and therefore
the versions and instructions on the display may vary. In the case of dis-
plays without warning or information texts, faults are indicated exclusively
by the warning lamps.
● Depending on the equipment, some settings and instructions can also
be carried out in the Easy Connect system.
● When several warnings are active at the same time, the symbols are
shown successively for a few seconds. The symbols will stay on until the
fault is rectified. 
Service interval display
The inspection message appears on the instrument panel display
⇒ Fig. 36 4.
SEAT makes a difference between services with engine oil change (Interval
Service) and services without engine oil change (Inspection Service). The
service interval display only gives information for service dates which in-
volve an engine oil change. The dates of the remaining services (for exam- ple, the next Inspection Service or change of brake fluid) are listed on the
label attached to the door strut, or even in the Maintenance Programme.
In vehicles with
Services established by time or mileage , the service inter-
vals are already pre-defined.
In vehicles with LongLife Service , the intervals are determined individually.
Technical progress has made it possible to considerably reduce servicing re-
quirements. The technology used by SEAT ensures that your vehicle only
has an Interval Service when it is necessary. To establish when the Interval
Service is due (max. 2 years), the vehicle's conditions of use and individual
driving styles are considered. The service pre-warning first appears 20 days
before the date established for the corresponding service. The kilometres
remaining until the next service are always rounded up to the nearest 100
km (miles) and the remaining time is given in complete days. The current
service message cannot be viewed until 500 km (miles) after the last serv-
ice. Prior to this only lines are visible on the display.
Inspection reminder
When the Service date is approaching, when the ignition is switched on a
Service reminder is displayed.
In vehicles without text messages , a spanner is displayed on the instrument
panel  with a figure given in km. The number of kilometres shown is the
maximum number that may be driven until the next service. After a few sec-
onds, the display mode changes. A clock symbol appears and the number
of days until the next service appointment is due.
In vehicles with text messages , Service in --- km (miles) or --- days is dis-
played on the instrument panel.
Service due
After the service date, an audible warning is given when the ignition is
switched on and the spanner displayed on the screen flashes for a few sec-
onds . In vehicles with text messages , Service in --- km or --- days is dis-
played on the instrument panel. 

68Instruments and warning/control lamps
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 215.
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. Gear-change indicator
This additional indicator function can help to save fuel.
Fig. 39 Instrument pan-
el: Gear-change indicator
(manual gearbox)
To familiarise yourself with the gear-change indicator, we recommend driv-
ing in the normal way to start with. A gear change will be recommended if
the gear you are in is not the most economical choice.
If no gear-change is recommended, you are already in the most economical
gear.
Vehicles with a manual gearbox
The following display symbols ⇒ Fig. 39 mean:
●  Change to a higher gear: The suggested gear appears to the right of
the current gear when a higher gear is recommended.
●  Change to a lower gear: The suggested gear appears to the left of the
current gear when a lower gear is recommended.
The gear recommendation may occasionally skip a gear (2nd  4th).

Instruments and warning/control lamps
Vehicles with an automatic gearbox*
The display is only visible in tiptronic mode ⇒ page 159
The following display symbols mean:
●  Shifting up a gear
●  Shifting down a gear
CAUTION
The gear-change indicator is intended to help save fuel. It is not intended to
recommend the right gear for all driving situations. In certain situations, on-
ly the driver can choose the correct gear (for instance when overtaking, driv-
ing up a steep gradient or towing a trailer).
Note
The display disappears from the instrument panel when you press the
clutch pedal. 
Control lamps Control and warning lamps
The control and warning lamps are indicators of warnings, ⇒ , faults ⇒ or certain functions. Some control and warning lamps come on when the ig-
nition is switched on, and switch off when the engine starts running, or
while driving.
Depending on the model, additional text messages may be viewed on the
instrument panel display. These may be purely informative or they may be
advising of the need for action ⇒ page 61, Instruments. Depending upon the equipment fitted in the vehicle, instead of a warning
lamp, sometimes a symbol may be displayed on the instrument panel.
When certain control and warning lamps are lit, an audible warning is also
heard.

Vehicles with multifunction steering wheel
–To display the engine oil temperature, enter the submenu Jour-
ney data and turn the thumbwheel until the oil temperature dis-
play appears.
The engine reaches its operating temperature when in normal driving condi-
tions, the oil temperature is between 80 °C (180 °F) and 120 °C (250 °F). If
the engine is required to work hard and the outside temperature is high, the
engine oil temperature can increase. This does not present any problem as
long as the warning lamps  ⇒ page 69 or  ⇒ page 70 do not appear on
the display. 
Additional electrical appliances
– Operation with the windscreen wiper lever*: Press the rocker
switch ⇒  Fig. 40 2 until the main menu appears. Enter into the

play appears.
In addition, a scale will inform you of the current sum of all the additional
appliances. 
Saving tips
Tips on how to save fuel will be displayed in certain conditions that
contribute to increased consumption. Following these tips could reduce the fuel consumption of your vehicle. The displays appear
automatically and will only be shown with the efficiency pro-
gramme. After a time, the saving tips will disappear automatically.
