2018 Seat Arona battery

The essentials
Make sure the battery clamps have sufficient
met al-t
o-met
al contact with the battery termi-
nals.
If the engine fails to start after about 10 sec-
onds, switch off the starter and try again after
about 1 minute. WARNING
● Ple a

se note the safety warnings referring to
working in the engine compartment
›››  page 273, Working in the engine
compartment.
● The battery providing assistance must have
the same v
oltage as the flat battery (12 V)
and approximately the same capacity (see
imprint on battery). Failure to comply could
result in an explosion.
● Never use jump leads when one of the bat-
teries
is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
awa
y from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufact
urer of the jump leads.
● Do not connect the negative cable from the
other vehic
le directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion. ●
Never att ac

h the negative cable to fuel sys-
tem components or the brake lines in the oth-
er vehicle.
● The non-insulated parts of the battery
clamp
s must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot c
ome into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult
in chemical burns. Note
The vehicles must not touch each other, oth-
erw i

se electricity could flow as soon as the
positive terminals are connected. Changing the windscreen wiper

Perfect windscreen wiper blade condition is
essential for clear vision. Damaged wiper
blades should be replaced immediately.
The windscreen wiper blades are supplied as
standard with a layer of graphite. This layer is
responsible for ensuring that the wipe is si-
lent. If the graphite layer is damaged, the
noise of the water as it is wiped across the
windscreen will be louder.
Check the condition of the wiper blades regu-
larly. If the wipers scrape across the glass ,
they should be changed if they are damaged,
or cleaned if they are dirty ››› .
If thi
s

does not produce the desired results,
the setting angle of the windscreen wiper
arms might be incorrect. They should be
checked by a specialised workshop and cor-
rected if necessary. WARNING
Do not drive unless you have good visibility
through a l

l windows! ●
Cle

an the windscreen wiper blades and all
windows regularly.
● The wiper blades should be changed once
or twice a
year. CAUTION
● Dam aged or dir

ty windscreen wipers could
scratch the glass.
● Never use fuel, nail varnish remover, paint
thinner or simil
ar products to clean the win-
dows. This could damage the windscreen
wiper blades.
● Never move any windscreen wiper by hand.
This c
ould cause damage.
● To prevent damage to the bonnet and the
winds
creen wiper arms, the latter should only
be lifted off the windscreen when in service
position. Note
● The wind s

creen wiper arms can be moved
to the service position only when the bonnet
is properly closed.
● You can also use the service position, for
examp
le, if you want to fix a cover over the
windscreen in the winter to keep it clear of
ice. Towing or tow-starting
Gener a

 page 70.
Tow-starting means starting the engine of
the vehicle while another pulls it.
Towing means one vehicle pulling another
that is not roadworthy.
If the vehicle comes with the Keyless Access
system, towing is only allowed with the igni-
tion on!
The vehicle battery drains if the vehicle is
towed with the engine switched off and the
ignition connected. Depending on the battery
charge status, the drop in voltage may be so
large, even after just a few minutes, that no
electrical device in the vehicle may work e.g.
the hazard warning lights. In vehicles with
the Keyless Access system, the steering
wheel could lock up. WARNING
If the vehicle has no electrical power, the
brak e light

s, turn signals and all other lights
will no longer function. Do not have the vehi-
cle towed away. Failure to follow this instruc-
tion could result in an accident. 100

Self-help
WARNING
The risk of accidents is high when tow-start-
ing, f or e
xample, the towed vehicle can easily
be driven into the towing vehicle. CAUTION
If there is no oil in the gearbox or no lubricant
in the autom atic

transmission the car may
only be towed with the driven wheels lifted
clear of the road, or transported on a special
car transporter or trailer. CAUTION
Do not tow a vehicle for more than 50 m in at-
tempt t

o start it. There is risk of damage to
the catalytic converter. Note
● Ple a

se observe related legal requirements.
● Switch on the hazard warning lights of both
vehicl
es. However, observe any regulations
to the contrary.
● The tow rope must not be twisted. Other-
wise the fr
ont tow line anchorage could be
pulled off the vehicle. Indications for tow-starting
Vehicle's should not generally be tow-star-
t
ed.
The jump s

tart should be used instead
›››  page 71. For technical reasons, towing the following
vehicl

es is not allowed:
● Vehicles with an automatic gearbox.
● If the vehicle battery is discharged, be-
cause in
vehicles with the Keyless Access
locking and ignition system the steering re-
mains locked and the electronic parking
brake cannot be deactivated nor can the elec-
tronic lock of the steering column be re-
leased if they are activated.
● If the battery is flat, it is possible that the
engine contr
ol units may not operate correct-
ly.
However, if the vehicle must absolutely be
tow-started (in the case of manual gearbox-
es):
● Engage the 2nd or 3rd gear.
● Keep the clutch pressed down.
● Switch on the ignition and the hazard warn-
ing lights.
● Once both

vehicles are moving, release the
clutc
h.
● Once the engine starts, press the clutch
and diseng
age the gear to avoid colliding
with the towing vehicle. Note
The vehicle can only be tow-started if the
electr onic

parking brake and, if appropriate,
the electronic lock of the steering column are deactivated. If the vehicle has no power sup-
ply
or ther

e is an electric system fault, the
engine must be tow-started to deactivate the
electronic parking brake and the electronic
lock of the steering column. 101

Changing bulbs requires a certain degree of
practical skill.
If you choose to change the engine compart-
ment lamps yourself, remember that it is a
dangerous area ››› in Safety notes for work
in the en gine c
omp

artment on page 273.
Always use identical bulbs with the same
designation. The name can be found on the
base of the bulb holder. Depending on how equipped the vehicle is,
there are diff

erent sets of headlights and tail
lights:
● Halogen headlights.
● Full-LED main headlights*
● Halogen headlights with LED daytime run-
ning lights*
● Re

ar bulb light
● LED rear light*
Ful
l-LED headlight system*
Full-LED headlights handle all light functions
(daylight, side light, turn signal, dipped
beam and route light) with light emitting di-
odes (LEDs) as a light source.
Full-LED headlights are designed to last the
lifetime of the vehicle and the bulbs cannot
be replaced. In case of headlight failure, go
to an authorised workshop to have it re-
placed. WARNING
● Tak e p

articular care when working on com-
ponents in the engine compartment if the en-
gine is warm, there is a risk of burns.
● Bulbs are highly sensitive to pressure. The
glas
s can break when you touch the bulb,
causing injury.
● When changing bulbs, please take care not
to injure
yourself on sharp parts in the head-
light housing. 106
