running. In this case power is consumed when
none is being gener at
ed.
In these sit
uations you will be aware that the
power management system is intervening to
control the distribution of electrical power.
When the vehicle is parked for long peri-
ods
If you do not drive your vehicle for a period of
several days or weeks, the power manage-
ment will gradually shut off the electrical de-
vices one by one or reduce the amount of
current they are using. This limits the amount
of power consumed and helps to ensure reli-
able starting even after a long period. Some
convenience functions, such as remote vehi-
cle opening, may not be available under cer-
tain circumstances. These functions will be
restored when you switch on the ignition and
start the engine.
With the engine switched off
For example, if you listen to the sound system
with the engine switched off the battery will
run down.
If the energy consumption means there is a
risk that the engine will not start, a text will
appear in vehicles with a driver information
system*.
This driver indicator tells you that you must
start the engine so that the battery can re-
charge. When the engine is running
Although the alternator gener
ates electrical
power, the battery can still become dis-
charged while the vehicle is being driven. This
can occur when a lot of power is being con-
sumed but only a small amount supplied, es-
pecially if the battery is not fully charged ini-
tially.
To restore the necessary energy balance, the
system will then temporarily shut off the elec-
trical devices that are using a lot of power, or
reduce the current they are consuming. Heat-
ing systems in particular use a large amount
of electrical power. If you notice, for instance,
that the seat heating* or the rear window
heater is not working, they may have been
temporarily switched off or regulated to a
lower heat output. These systems will be
available again as soon as sufficient electri-
cal power is available.
You may also notice that the engine runs at a
slightly faster idling speed when necessary.
This is quite normal, and no cause for con-
cern. The increased idling speed allows the
alternator to meet the greater power require-
ment and charge the battery at the same
time. Engine management and

to the presence of metallic objects (e.g. rails
on the r oad or sheets used in r
oad w
orks).
The area in front of and around the radar
sensor should not be covered with adhesives,
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, for example if the suspension is lowered,
Front Assist operation may be affected. SEAT
recommends visiting a SEAT dealership for
this purpose. CAUTION
If you have the sensation that the radar
sensor is damaged or has lost its settings, disconnect the Fr ont Assist. This will av

oid
possible dangerous situations caused by a
system malfunction. If this occurs have it
adjusted.

ects the possible
lines dividing the lanes. When the vehicle in-
voluntarily approaches a dividing line it has
detected, the system notifies the driver with a
corrective steering movement. The purpose is
not only to warn the driver, but also to keep
the vehicle inside the lane. This movement
can be over-regulated at any time.
No warning is produced with the turn signals

Fuel Identification of the fuel 1)Fig. 306
Identification of fuels according to
Eur opean Union (EU) Dir
ectiv
e 2014/94/Fuels are identified with different symbols.
Depending on the fuel, the diff
er
ent symbol

s
are on the pump and the tank lid of your vehi-
cle. The identification serves to prevent con-
fusion when choosing the fuel.
Petrol with ethanol (“E” stands for Etha-
nol). The number indicates the percent-
age of ethanol in the petrol. “E5” means,
for example, an ethanol ratio of 5% max.
Diesel with biodiesel (“B” stands for Bio-
diesel). The number indicates the per-
1 2 centage of biodiesel in the diesel. “B7”
means, f
or e
x

ample, a proportion of bio-
diesel of max. 7%.
Natural gas: “CNG” means Compressed
Natural Gas.
Type of petrol  Applies to vehicles: with petrol engine
The corr ect gr

ade of petrol is listed 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) 2)
. The types of petrol are differentiated
by using the octane numbers (RON) or via
the anti-knock index (AKI).
The following pieces of text show the infor-
mation included in the corresponding stickers
on the tank lid (examples): 3 Super unleaded petrol 95 octane petrol or
normal 91 oct

east
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).
Super unleaded petrol, 95 octanes at
least
You should use super 95 octane petrol (91
AKI) at least.
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.
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
