ed.WARNING
Never ignore the warning lamps or messag-
es.

Driving
The area in front of and around the radar
sensor shoul d not be co
ver
ed with adhesiv
es,
additional or similar headlights, as this may
negatively affect Front Assist operation.
If the front of the vehicle is not properly re-
paired or structural modifications are made
to it, Front Assist operation may be affected.
SEAT recommends visiting a SEAT dealership
for this purpose. CAUTION
If you have the feeling that the radar sensor
is damaged or has lost its settings, discon-
nect the Front Assist. This will avoid possi-
bl e danger

ous situations caused by the in-
adequate operation of the system. If this
occurs have it adjusted.

Driver assistance systems
Overtaking
When the t urn signal lights up bef
ore the v
e-
hicl
e starts to overtake, the ACC accelerates
the vehicle automatically and thus reduces
the distance from the vehicle in front.
When the vehicle moves to the overtaking
lane, if the ACC does not detect another ve-
hicle in front, it accelerates until it reaches the
programmed speed.
System acceleration can be interrupted at
any time by pressing the brake or moving the
third lever to position 

Driving
Lane Assist with lane centring guide
The Lane Centring Guide function is inten-
ded t o keep the v

If the driver has a tendency to veer slightly off
centre in the lane, the system adapts to driver
preferences.

Type of petrol  Valid for: vehicles with petrol engines
The correct grade of petr ol is list

ed inside the
fuel tank flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded
petrol. The petrol must comply with the
standard EN 228 and be sulphur-free. Fuels
with a 10% ethanol ratio can be refuelled
(E10) 1)
. The types of petrol are differentiated
by using the octane numbers (RON) or via
the anti-knock index (AKI).
Super unleaded petrol 95 octane petrol or
normal 91 octane petrol at least
We recommend refuelling with super 95 oc-
tane petrol (91 AKI). If not available, normal 91
octane petrol (87 AKI) (with a slight power
loss) may be used.
Super unleaded petrol, 95 octanes at
least
You should use super 95 octane petrol (91
AKI) at least. 3 If super is not available, if necessary, use nor
-
mal 91 oct ane petrol (87 AKI). In this case only
use moder at

e engine speeds and a light
throttle. Refuel with super as soon as possi-
ble.
Unleaded super plus 98 octane petrol or
super 95 octane petrol at least
We recommend refuelling with super plus 98
octane petrol (93 AKI). If not available: super
95 octane petrol (91 AKI) (with a slight power
loss).
If super is not available, if necessary, use nor-
mal 91 octane petrol (87 AKI). In this case only
use moderate engine speeds and a light
throttle. Refuel with super as soon as possi-
ble. CAUTION
