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.

Driving
Start-Stop System*
If the vehicle is stopped and the Start-Stop system* switches off the engine,
the ignition remains switched on.
Automatic gearbox: Before leaving the vehicle, make sure that the ignition
is switched off and the selector lever is in position P.
Driver messages on the instrument panel display
Press the clutch This message appears on vehicles with a manual gearbox if the driver tries
to start the engine without having the clutch pedal pressed. The engine will
only start if you press the clutch pedal.
Press the brake
This message appears on vehicles with an automatic gearbox if the driver
tries to start the engine without having the brake pedal pressed.
Select N or P
This message appears if you try to start or stop the engine when the selec-
tor lever of the automatic gearbox is not in position P or N. The engine can
only start or stop in these positions.
Engage position P; the vehicle can move; doors can only close in position P. For safety reasons, this driver message appears and an audible warning
sounds if the selector lever of the automatic gearbox is not in position P af-
ter you switch off the ignition. Otherwise the vehicle could move.
Gear change: selector lever in the drive position! This driver message is displayed and a buzzer is sounded when the selector
lever is not in the position P when the driver door is opened. Put the selec-
tor lever in position P; otherwise the vehicle can roll away.
Ignition is switched onThis driver message is displayed and a buzzer is sounded when the driver
door is opened with the ignition switched on.
WARNING
● Never run the engine in confined spaces, as the exhaust gases are
poisonous.
● Never remove the key from the ignition if the vehicle is in motion.
Otherwise, the steering could suddenly lock, making it impossible to
steer the vehicle: risk of accident!
● Always take the key with you when you leave the vehicle. This is par-
ticularly important if there are children in the vehicle, as they might oth-
erwise be able to start the engine or use power-operated equipment (e.g.
the electric windows), which could cause injuries.
CAUTION
Avoid high engine speeds, full throttle and extreme load conditions until
the engine has reached its normal operating temperature, otherwise this
can damage the engine.
For the sake of the environment
Do not warm up the engine by running it with the car stationary. You should
drive off as soon as you start the engine. This will help avoid unnecessary
exhaust emissions.
Note
● If it is difficult to turn the ignition key to the position 1, turn the steer-
ing wheel to both sides to release the steering lock.
● 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 lifters. This is
quite normal, and no cause for concern.
● If the vehicle battery is disconnected and reconnected, the key must re-
main in the position 1
for around 5 seconds before starting up.
● Vehicles with automatic gearbox: After switching off the ignition, you
can only remove the ignition key if the selector lever is in position “P” (park-
ing lock). Next, the selector lever is locked. 
