CAUTION
● To prevent damage to the engine, the rev counter needle should only re-
main in the red zone for a short period of time.
● When the engine is cold, avoid high revs and heavy acceleration and do
not make the engine work hard.
For the sake of the environment
Changing up a gear in time reduces fuel consumption and noise. 

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.

WARNING (Continued)
● Before opening the bonnet, switch off the engine and allow it to cool.
● In any vehicle, the engine compartment is a hazardous area and could
cause severe injuries ⇒ page 209.
CAUTION
Failure to heed the control lamps and text messages when they appear may
result in faults in the vehicle. 

Opening and closing
To deactivate the alarm, press the button 
on the remote control key, or
switch on the ignition. After a certain time, the alarm will automatically
switch off.
Switch off the vehicle interior monitoring and tow-away protection if you
wish to prevent the alarm from being triggered accidentally ⇒ page 95.
Turn signals
The turn signals will flash twice when the vehicle is unlocked and once
when the vehicle is locked.
If the signals do not flash, this indicates that one of the doors, the rear lid or
the bonnet is not closed correctly.
Accidental lock-out
The central locking system prevents you from being locked out of the vehi-
cle in the following situations:
● If the driver door is open, the vehicle cannot be locked with the central
locking switch ⇒ page 93.
Lock the vehicle with the remote control key, when all the doors and the rear
lid have been closed. This prevents the accidental locking of the vehicle.
WARNING
Do not leave anyone (especially children) in the vehicle if it is locked from
the outside and the anti-theft security system* is enabled, as the doors
and windows cannot then be opened from the inside. Locked doors could
delay assistance in an emergency, potentially putting lives at risk.
Note
● Never leave any valuable items in the vehicle unattended. Even a locked
vehicle is not a safe.
● If the diode on the driver door sill lights up for about 30 seconds when
the vehicle is locked, the central locking system or anti-theft alarm* is not
working properly. You should have the fault repaired at a SEAT Official Serv-
ice or specialised workshop.
● The vehicle interior monitoring of the anti-theft alarm* system will only
function as intended if the windows and the sunroof* are closed. 

How to turn OFF the alarm

the rear lid is also opened.
● The anti-theft alarm 
is not activated when the vehicle is locked from
the inside using the central locking button. ●
