warning light Seat Arona 2018 Repair Manual

Operation
WARNING
● Before opening the bonnet, read and ob-
serve the warnings ››› page 273, Working in
the engine compartment.
● If the br
ake system warning lamp  should
light up together with the ABS warning lamp
, stop the vehicle immediately and check
the brake fluid level in the reservoir
››› page 280, Brake fluid. If the brake fluid
lev

el has dropped below the “MIN” mark you
must not drive on. Risk of accident. Obtain
technical assistance.
● If the brake fluid level is correct, the fault in
the brake system may have been caused by a
failure of the ABS system. This could cause
the rear wheels to lock quickly when you
brake. This could cause the rear to break
away. Risk of skidding. Stop the vehicle and
seek technical assistance. Electronic differential lock (XDS)*
When taking a curve, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In
this way, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected or the ESC is
in Sport mode.
Mul t
i
-collision Brake In an accident, the multi-collision brake can
help the driver by braking to avoid the risk of
skidding during the accident, which could
lead to further collisions.
The multi-collision brake works for front, side
or rear accidents, when the airbag control
unit records its activation level and the acci-
dent takes place at a speed of over 10 km/h
(6 mph). The ESC automatically brakes the
vehicle, as long as the accident has not dam-
aged the ESC, the brake hydraulics or the on-
board network
The following actions control automatic brak-
ing during the accident:●
When the driver presses the accelerator,
the automatic braking does not take place.
● When the braking pressure through press-
ing the brake pedal is greater than the sys-
tem’s braking pressure the vehicle will brake
automatically.
● Multi-collision braking will not be available
if ESC is malfunctioning.
Brake servo The brake servo increases the pressure you
apply to the brake pedal. It works
only when
the engine is running .
If the brake servo is not functioning, e.g. due
to a malfunction, or if the vehicle is being
towed, you will have to press the brake pedal
considerably harder to make up for the lack
of servo assistance. WARNING
The braking distance can also be affected by
external factors.
● Never let the vehicle coast with the engine
switched off. Failure to follow this instruction
could result in an accident. The braking dis-
tance is increased considerably when the
brake servo is not active.
● If the brake servo is not working, for exam-
ple when the vehicle is being towed, you will
have to press the brake pedal considerably
harder than normal. 186 *

Driving
Hill driving assistant* Fig. 179
Related video This function is only included in vehicles with
ESC.
The hi l
l driving assistant helps the driver to
move off and upward on a hill when the vehi-
cle is stationary.
The system maintains brake pressure for ap-
proximately two seconds after the driver
takes his foot off the brake pedal to prevent
the vehicle from lurching backward when it is
started. During these 2 seconds, the driver
has enough time to release the clutch pedal
and accelerate without the vehicle moving
and without having to use the handbrake,
making start-up easier, more comfortable
and safer.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● driver door closed,
● vehicle completely stationary,
● engine running and foot on the brake, ●
bes ide

s having a gear engaged or being in
neutral for manual gear change and with the
selector lever at position S, D or R for an au-
tomatic gearbox.
This system is also active when reversing up-
hill. WARNING
● If y

ou do not start the vehicle immediately
after taking your foot off the brake pedal, the
vehicle may start to roll back under certain
conditions. Depress the brake pedal or use
the hand brake immediately.
● If the engine stalls, depress the brake ped-
al or u
se the hand brake immediately.
● When following a line of traffic uphill, if you
want t
o prevent the vehicle from rolling back
accidentally when starting off, hold the brake
pedal down for a few seconds before starting
off. Note
The Official Service or a specialist workshop
can t el

l you if your vehicle is equipped with
this system. Manual gearbox

ith a manual gearbox Read the additional information carefully
›› ›

 page 49
Certain versions of the model may include a
6-speed manual gearbox, and its diagram is
shown on the gearbox lever.
The reverse gear can only be engaged when
the car is stationary. When the engine is run-
ning and before engaging this gear, wait
about 6 seconds with the clutch pressed
down thoroughly in order to protect the gear-
box.
The reverse lights switch on when the reverse
gear is selected and the ignition is on. WARNING
● When the engine i s

running, the vehicle
will start to move as soon as a gear is engag-
ed and the clutch released.
● Never select the reverse gear when the ve-
hicle i
s in motion. Risk of accident. Note
● Do not r e

st your hand on the gear lever
while driving. The pressure of your hand
could cause premature wear on the selector
forks in the gearbox. » 187

Operation
WARNING
Observe the safety warnings ››› in Selector
lev er po
sitions on page 189.
● Never allow the brake to rub and do not use
the brake ped
al too often or for long periods.
Constant braking causes overheating in the
brakes. This could significantly reduce brak-
ing power, increase braking distance or even
result in the total failure of the brake system.
● To avoid rolling back on gradients always
hold the
vehicle with the footbrake or hand-
brake if you have to stop. CAUTION
● If y

ou stop the vehicle on a gradient, do not
attempt to stop it from rolling by depressing
the accelerator when a gear has been selec-
ted. This could cause overheating and dam-
age the automatic gearbox. Apply the hand-
brake firmly or press the brake pedal in order
to prevent the vehicle from rolling back.
● If you allow the car to roll with the selector
lever in po
sition N with the engine switched
off, the automatic gearbox will be damaged
as it will not be lubricated.
● In certain driving situations or traffic condi-
tions, suc
h as frequently starting, prolonged
“creeping” of the vehicle or traffic jams with
continuous stoppages, the gearbox could overheat causing damage! If the warning
lamp


lights up, stop the vehicle as soon as
possible and wait for the gearbox to cool
››› page 194. Kick-down feature
The kick-down feature allows maximum ac-
cel
er

ation to be reached.
When the accelerator pedal is pressed right
down past the point of resistance at full throt-
tle, the gearbox will shift down to a lower
gear, depending on road speed and engine
speed. The upshift to the next higher gear is
delayed until the engine reaches maximum
rpm. WARNING
Please note that if the road surface is slip-
pery or w

et, the kick-down feature could
cause the driving wheels to spin, which could
result in skidding. Launch control program

D SG w

ith diesel engines superior to 125 kW and pet-
rol engines superior to 140 kW.
The Launch control programme enables maxi-
mum acceleration.
Important: the engine must have reached op-
erating temperature and the steering wheel

Operation
The driver message Inertia wi
l l be dis-
played. At speeds higher than 20 km/h (12
mph), the gearbox will automatically disen-
gage and the vehicle will roll freely, without
the effect of the engine brake. While the vehi-
cle rolls, the engine runs at idling speed.
Stopping inertia mode
– Press the brake or the accelerator pedal.
To mak
e use of the braking force and switch
off the engine again, simply press the brake
pedal briefly.
Applying both the inertia mode (= prolonged
section with less energy) and the switching
off using inertia (= shorter section without
the need for fuel) facilitates improved fuel
consumption and emission balance. WARNING
● If the iner ti

a mode has been switched on,
take into account, when approaching an ob-
stacle and releasing the accelerator pedal,
that the vehicle will not decelerate in the usu-
al manner: risk of accident!
● When using inertia mode while travelling
down hil
ls, the vehicle can increase speed:
risk of accident!
● If other users drive your vehicle, warn them
about inerti
a mode. Note
● Inerti a mode i

s only available in eco (SEAT
Drive Profile*) driving mode.
● The driver message Inertia is on
ly dis-
played with the current consumption. In iner-
tia mode the gear will no longer be displayed
(for example “E” will appear instead of “E7”).
● On downhill sections with gradients above
15 %, the inertia mode w
ill automatically be
switched off temporarily. Emergency program
A backup programme is in place if a fault

d oc

cur in the control system.
If all the positions of the selector lever are
shown over a light background on the instru-
ment panel display, there is a system fault
and the automatic gearbox will operate in
with the backup programme. When the back-
up programme is activated, it is possible to
drive the vehicle, however, at low speeds and
within a selected range of gears. In some ca-
ses driving in reverse gear may not be possi-
ble. CAUTION
If the gearbox operates with the backup pro-
gramme, t ak

ages are ignored when they light up, the
vehicle may stall in traffic and cause acci-
dents and severe injuries. ●
Never ignor e the w

arning lamps or messag-
es.
● Stop the vehicle at the next opportunity
and in a safe p
lace. Note
Failure to heed the control lamps and corre-
s pondin g t

ext messages when they light up
may result in damage to the vehicle. Information relating to different vehi-
c

al, you should always lock the steering be-
fore leaving the vehicle.
Mechanical steering lock
The steering column is locked when the key
is removed from the ignition lock and the ve-
hicle is stationary.
Activating the steering lock
● Park the vehicle ›››
page 179.
● Remove the ignition key.
● Turn the steering wheel slightly until the
steerin
g lock has engaged.

Driving
Deactivating the steering lock
● Turn the steering wheel slightly to release
the loc k.
● Inser
t the key in the ignition lock.
● Hold the steering wheel in this position
and switc
h on the ignition.
Electromechanical steering
In vehicles with electromechanical steering,
the assisted steering function automatically
adjusts according to vehicle speed, steering
wheel torque and wheel orientation. The
power steering only works when the engine
is running.
You should take into account that you will
need considerably more power than normal
to steer the vehicle if the power steering is
not working correctly or at all.
Power-assisted steering
Power-assisted steering helps the driver in
critical situations. In counter-steering, it as-
sists by applying additional torque ››› .
WARNING
Power-assisted steering, together with the
ESC, help s

the driver to control vehicle steer-
ing in critical situations. However, the driver
is ultimately responsible for steering the ve-
hicle at all times. Power-assisted steering
does not remove this responsibility. Run-in and economical driving
R u
nnin

g in a new engine The engine needs to be run-in over the first
1500 km (900 mil
e

s).
For the first 1,000 kilometres (600 miles)
– Do not drive at speeds of more than 2/3
the maximum s

peed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1,000 k i

lometres (600 miles) to 1,500
kilometres (900 miles)
– Speeds can be gradual
ly increased to the
maximum road speed or maximum permis-
sible engine speed (rpm).
During its first few hours of running, the in-
ternal friction in the engine is greater than
later on, when all the moving parts have bed-
ded in. For the sake of the environment
If the engine is run in gently, its life will be in-
cr e

ased and its oil consumption reduced. Running in tyres and brake pads
New tyres should be run in carefully for the
firs
t

500 km (300 miles) and new brake pads
should be run in carefully for the first 200 km
(125 miles).
During the first 200 km (125 miles) you have
to compensate for the reduced braking effect
by applying more pressure to the brake ped-
al. In case of a sharp braking, the braking
distance will be longer with new brake pads
than with brake pads which have been run-
in. WARNING
● At fir s

t, new tyres do not give maximum
grip, and require running-in. This may cause
an accident. Drive particularly carefully in the
first 500 km (300 miles).
● New brake pads must be “run in” and do
not hav
e the correct friction properties during
the first 200 km (125 miles). However, the re-
duced braking capacity may be compensated
by pressing on the brake pedal a little harder. Environmental compatibility

Introduction WARNING
● Bec au

se of the high temperatures which
can occur in the exhaust purification system
(catalytic converter or diesel particulate fil-
ter), do not park the vehicle where the ex-
haust can come into contact with flammable
materials under the car (e.g. on grass or at
the forest edge). Fire hazard!
● Do not apply wax underneath the vehicle
around the ar
ea of the exhaust system: Fire
hazard! Note
While the control lamps , ,  or  re-
m ain lit, ther

e may be engine problems, fuel
consumption may increase and the engine
may lose power. Catalytic converter
To maintain the useful life of the catalytic
con
v

erter
– Use only unleaded petrol with petrol en-
gines, as

lead damages the catalytic con-
verter.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish
with too muc

h engine oil ››› page 277, Top-
ping up engine oil.
– Never tow the vehicle to start it, use jump
lea

ds if necessary ›››
 page 71.
If you notice misfiring, uneven running or
loss of power when the vehicle is moving, re-
duce speed immediately and have the vehi-
cle inspected at the nearest specialised
workshop. In general, the exhaust warning
lamp will light up when any of the described
symptoms occur ›››
page 121. If this hap-
pens, unburnt fuel can enter the exhaust sys-
tem and escape into the environment. The
catalytic converter can also be damaged by
overheating. CAUTION
Never run the fuel tank completely dry be-
cau se the irr

egularity of the fuel supply may
cause ignition problems. This allows unburnt
fuel to enter the exhaust system, which could
cause overheating and damage the catalytic
converter. For the sake of the environment
Even when the emission control system is
work in

g perfectly, there may be a smell of
sulphur from the exhaust gas under some
conditions. This depends on the sulphur con-
tent of the fuel used. Quite often the problem
can be solved by changing to another brand
of fuel. Diesel particulate filter
3 App
lies to vehicles with diesel engine
The die
sel engine particulate filter eliminates
most of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. The diesel particulate filter is
cleaned automatically without need for indi-
cation by the warning lamp . This may be
noticed because the engine idle speed in-
creases and an odour may be detected.
If automatic filter purification cannot be car-
ried out (because only short trips are taken,
for example), soot will accumulate on the fil-
ter and the Diesel particulate filter warning
lamp will  switch on.
Facilitate the automatic filter cleaning proc-
ess by driving in the following manner: drive
for approximately 15 minutes at a minimum
speed of 60 km/h (37 mph) in 4th or 5th gear
(automatic gearbox: gear S). Maintain the en-
gine speed at approximately 2,000 rpm. The
rise in temperature causes the soot on the
200

Driving
filter to burn. On completion of the cleaning
the w arnin
g l
amp will switch off. If the warn-
ing lamp does not switch off, go immediately
to a specialised workshop to rectify the prob-
lem.
Engine management*  This warning lamp monitors the engine man-
agement
sy

The warning lamp  (Electronic Power Con-
trol) lights up when the ignition is switched
on while system operation is being verified. It
should go out once the engine is started.
If there is a fault in the electronic engine
management system while you are driving,
this warning lamp will light up. Take the vehi-
cle to a specialised workshop as soon as
possible and have the engine checked.

oad To drive abroad, the following must be taken
into c
on

sideration:
● For vehicles fitted with a catalytic converter
ensur
e that unleaded petrol is available for
the journey. See chapter ››› page 269, Fuel.
Automobile organisations will have informa-
tion about service station networks selling
unleaded fuel.
● In some countries, it is possible that your
car model i

s not sold, and therefore some
spare parts are not available or the technical
services may only be able to carry out limited
repairs.
SEAT importers and distributors will gladly
provide information about the technical prep-
aration that your vehicle requires and also
about necessary maintenance and repair
possibilities.

– Before stopping the vehicle or when it is
st
op

ped, put it into neutral and release the
clutch pedal. The engine will switch off. The
warning lamp  will appear on the instru-
ment panel display. The engine may stop
before the vehicle comes to a halt in the
deceleration phase (at 7 km/h).
– When the clutch pedal is pressed the en-
gine wil

l start up again. The warning lamp
will switch off. Vehicles with an automatic gearbox
– Use the foot brake to bring the vehicle to a
stop and k

eep the brake pedal pressed
down with your foot. The engine will switch
off. The warning lamp  will appear in the
display. The engine may stop before the ve-
hicle comes to a halt in the deceleration
phase (at 7 km/h or 2 km/h, depending on
the vehicle’s gearbox).
– When you take your foot off the brake pedal
the engine wi

ll start up again. The warning
lamp will switch off.
Additional information related to the auto-
matic gearbox
The engine stops when the selector lever is in
the positions P, D, N and S, in addition to
when in manual mode. With the selector lev-
er in position P, the engine will also remain
switched off when you take your foot off the
brake pedal. In order to start the engine up
again the accelerator must be pressed, or an-
other gear engaged or the brake released.
If the selector lever is placed in position R
during the stopping phase, the engine will
start up again.
