2018 Seat Arona engine overheat

Instruments and warning/control lamps
Normal temperature
If in norm
al
operations, the diodes light up
until the central zone, it means that the en-
gine has reached operating temperature. At
high outside temperatures and when making
the engine work hard, the diodes may contin-
ue lighting up and reach the upper zone. This
is no cause for concern, provided the control
lamp  does not light up on the instrument
panel digital display.
Heat range
When the diodes light up in the upper area of
the display and the control lamp appears 
on the instrument panel display, the coolant
temperature is excessive ››› page 278. CAUTION
● To en s

ure a long useful life for the engine,
avoid high revs, driving at high speed and
making the engine work hard for approxi-
mately the first 15 minutes when the engine
is cold. The phase until the engine is warm al-
so depends on the outside temperature. If
necessary, use the engine oil temperature*
›››  page 42 as a guide.
● Additional lights and other accessories in
front of
the air inlet reduce the cooling effect
of the coolant. At high outside temperatures
and high engine loads, there is a risk of the
engine overheating.
● The front spoiler also ensures proper distri-
bution of the c
ooling air when the vehicle is moving. If the spoiler is damaged this can re-
duce the c
oo

ling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel level

only works when the
ignition is switched on. When the display rea-
ches the reserve mark, the lower diode lights
up in red and the control lamp  appears

Air conditioning
●
At lo w out
side temperatures, the compres-
sor switches off automatically and cannot be
switched on even with the AUTO button.
● It is advisable to turn on the air condition-
ing at l

east once a month, to lubricate the
system gaskets and prevent leaks. If a de-
crease in the cooling capacity is detected, a
Technical Service should be consulted to
check the system.
● To ensure correct operation, the grilles on
both sides
of the screen must not be obstruc-
ted. ●
When the engine i s

under extreme strain,
switch off the compressor for a moment. Economic use of the air conditioning
When the air conditioning is switched on, the
compr
e

ssor consumes engine power and has
influence on fuel consumption. Consider the
following points in order to have the system
operating in the minimum possible time. ●
If the v

ehicle interior has overheated due to
an excessive solar radiation, it is best to
open the windows or doors to allow the hot
air to escape.
● While in motion, the air conditioning
should not
be switched on if the windows are
open.

hing it off.
● If the engine is cold, avoid high engine
speeds, p
ushing the engine too hard and rap-
id acceleration.
● Do not start the engine by pushing the ve-
hicle or t
owing it. Unburnt fuel could enter
the catalytic converter and damage it. Note
● Do not wait

until the engine warms up with
the vehicle stationary; if you have good visi-
bility through the windows, start driving im-
mediately. This helps the engine reach oper-
ating temperature faster and reduces emis-
sions.
● Electrical components with a high power
cons
umption are switched off temporarily
when the engine starts.
● When starting with a cold engine, noise
level
s may briefly increase. This is quite nor-
mal, and no cause for concern.
● When the outside temperature is below
+5°C (+41°F), if the en
gine is diesel, some
smoke may appear under the vehicle when
the fuel-operated auxiliary heater is on. Stopping the engine

6.If the vehicle is equipped with a manual
gearbox, put it into 1st or reverse. WARNING
Never switch off the engine while the vehicle
is mo

ving. This could cause loss of control of
the vehicle, accidents and serious injury.
● The airbags and belt tensioners do not
work when the ignition i
s switched off.
● The brake servo does not work with the en-
gine off. Ther
efore, you need to press the
break pedal harder to brake the vehicle.
● Power steering does not work when the en-
gine is not
running. You need more strength
to steer when the engine is switched off. ●
If the ignition i s

switched off, the steering
column could be locked, making it impossible
to control the vehicle. CAUTION
If the engine is made to work hard for a long
time, it ma

y overheat after being switched
off. To prevent damage to the engine before
switching it off, leave it idle for approx. 2 mi-
nutes in neutral. Note
After switching off the engine, the cooling fan
ma y

continue to operate in the engine com-
partment for a few more minutes, even with
the ignition off. The radiator fan is automati-
cally switched off. “My Beat” Function
For vehicles with a convenience key there is
the “M

an additional indication of the vehicle igni-
tion system.
When accessing the vehicle, e.g. by opening
the doors with the remote control, the START ENGINE STOP button flashes, calling at-
t ention t
o the r

elevant starter system button.
Upon switching the ignition on/off, the light
of the START ENGINE STOP button flashes. With

Braking and parking Brakin
g capacity and braking distance The efficiency of the brakes depends directly
on the br
ak
e p

ad wear. This wear depends to a great extent on the conditions under which
the vehic

le is operated and the way the vehi-
cle is driven. If you often drive in town, drive
short distances or have a sporty driving style,
we recommend that you have the thickness
of your brake pads checked by technical serv-
ices more frequently than recommended in
the Maintenance Programme.
If you drive with wet brakes, for example, af-
ter crossing areas of water, on days of heavy
rainfall or even after washing the car, the ef-
fect of the brakes is reduced as the brake
discs are wet or even frozen (in winter): in
this case, the brakes should be “dried” by
pressing the brake pedal several times. WARNING
Longer braking distances and faults in the
brak e sy

stem increase the risk of accidents.
● New brake pads must be run in and do not
have the c
orrect friction during the first
200 km (124 miles). This reduced braking ca-
pacity may be compensated for by pressing
on the brake pedal a little harder, which also
applies when the brake pads have to be
changed further on.
● If brakes are wet or frozen, or if you are
driving on r
oads which have been salted,
braking power may be lower than normal.
● On steep slopes, if brakes are excessively
used, they w
ill overheat. Before driving down
a long steep slope, it is advisable to reduce
speed and change down into a lower gear or range (depending on the type of transmis-
sion).
Thu

s, make use of engine braking and
relieve the brakes.
● Never let the brakes “drag” by applying
light pre
ssure. Continuous braking will cause
the brakes to overheat and the braking dis-
tance will increase. Apply and then release
the brakes alternately.
● Never let the vehicle run with the engine
switc
hed off. The braking distance is in-
creased considerably when the brake servo is
not active.
● If the brake fluid loses its viscosity and is
subj
ected to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes.
● Non-standard or damaged front spoilers
coul
d restrict the airflow to the brakes and
cause them to overheat. Before purchasing
accessories please observe the relevant in-
structions ››› page 259, Technical modifica-
tions.
● If a brake system circuit fails, the braking
dist
ance will be increased considerably. Con-
tact a specialised workshop immediately and
avoid unnecessary journeys. Control lamp

a fault in the brake system.
This warning lamp can light up together with
the ABS system warning lamp. WARNING
● If the br ak

e warning lamp does not go out
or if it lights up when driving, the brake fluid
level in the reservoir is too low so there is a
risk of an accident ››› page 280, Brake fluid.
Stop the vehicle and do not drive on. Obtain
technical assistance.
● If the brake warning lamp lights up  to-
gether w
ith the ABS lamp  this could be
due to an ABS fault. 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. Handbrake

the vehicle from accidentally rolling
away. Always apply the handbrake when you
leave your vehicle and when you park.
Applying the handbrake
– Pull the handbrake lever up firmly

tion switched on. The warning lamp turns off
when the handbrake is released. WARNING
● Never u se the h

andbrake to stop the vehi-
cle when it is in motion. The braking distance
is considerably longer, because braking is
only applied to the rear wheels. Risk of acci-
dent!
● If the handbrake is only partially released,
this w
ill cause the rear brakes to overheat,
which can impair the function of the brake
system and could lead to an accident. This al- so causes premature wear on the rear brake
pa
d

s. CAUTION
Always apply the handbrake before you leave
the vehic

le. Put it in 1st gear as well. In vehi-
cles with an automatic gearbox, place the
gear lever in position P. Parking
The handbrake should always be firmly ap-
p
lied when the
v

ehicle is parked.
Always note the following points when park-
ing the vehicle: – Use the brake pedal to stop the vehicle.
– Apply the handbrake.
– Put it in 1st gear.
– Switch the engine off and remove the key
from the ignition. T

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

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

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
