check engine Seat Arona 2020 Owner's Manual

Start and driving
The engine takes a long time to warm up
when it is idling. Mechanical w ear and pollu-
t ant emissions ar e al
so especially high during
this initial w
arm-up phase. It is therefore best
to drive off immediately after starting the en-
gine. Avoid running the engine at high speed.
Regular maintenance
Regular servicing helps in saving fuel even
before the engine is started. A well-serviced
engine gives you the benefit of improved fuel
efficiency as well as maximum reliability and
an enhanced resale value. A badly serviced
engine can consume up to 10% more fuel
than necessary.
Avoid short journeys
The engine and catalytic converter need to
reach their optimal operating temperature
in order to minimise fuel consumption and
emissions.
A cold engine consumes a disproportionate
amount of fuel. The engine reaches its work-
ing temperature after about four kilometres
(2.5 miles), when fuel consumption will return
to a normal level.
Check tyre pressure
Always make sure the tyres are inflated to the
correct pressures

Driving
The control lamps light up together when the
ignition is s wit
ched on and shoul d t
urn off af
-
ter approximately 2 seconds. This is the time
taken for the function check.
Brake assist systems Electronic Stability Control (ESC)*
The ESC helps to improv
e saf

ety. It reduces
the tendency to skid and improves the stabili-
ty and roadholding of the vehicle. The ESC
detects critical handling situations, such as
vehicle understeer or oversteer, or wheelspin
on the driving wheels. It stabilises the vehicle
by braking individual wheels or by reducing
the engine torque. The warning lamp will
flash on the instrument panel when the ESC is
intervening !.
The ESC includes the anti-lock brake system
(ABS), the hydraulic brake assist (HBA), the
traction control system (ASR), electronic dif-
ferential lock (EDS), electronic torque control
(XDS).
ESC also helps stabilise the vehicle by
changing the torque.
The ASR can be deactivated when wheel spin
is desirable

Ethanol fuel  Valid for: vehicles with Totalflex engines
You can recognise v ehicl
es with Totalflex en-
gines 1)
by label on the fuel tank lid with with
the marking “Petrol/ethanol”.
Vehicles with Totalflex engine can run with
unleaded petrol (95 octane / 91 AKI) accord-
ing to ANP No. 57 and with fuels with any high
percentage of ethanol. The vehicle is refuel-
led in the same way as petrol refuelling.

Note
The layout of parts may vary depending on
the engine. Engine oil
General notes The engine comes with a special, multi-grade
oil that can be used all year round.
Because the use of high-quality oil is essen-
tial for the corr
ect oper
ation of the engine
and its long useful life, when topping up or
changing oil, use only those oils that comply
with VW standards.
We recommend that the oil change be done
by a technical service or specialised work-
shop.
If the engine oil level is too low
You can get information about the correct en-
gine oil for your vehicle at your workshop.
If the recommended engine oil is not availa-
ble, in the event of an emergency you can
change the oil once with a maximum of 0.5 L
of the next oil until the next oil change:
Petrol engines: standard VW 504 00,
VW 502 00, VW 508 00, ACEA C3 or
API SN.

Warning lamp 
It lights up
Alternator fault. The control lamp lights up when the ignition is
switched on. It should go out when the engine
has st art
ed running.
If the control lamp  lights up while driving, the alternator is no longer charging the bat-
tery. You should immediately drive to the
nearest specialised workshop.
You should avoid using electrical equipment
that is not absolutely necessary because this
will drain the battery.
Checking the battery electrolyte
level The electrolyte level should be checked reg-
ul
arly in high-mil
eage vehicl
es, in hot coun-
tries and in ol

der batteries.
