Reading the vehicle fault memory
There is a diagnostics connector in the vehi-
cle interior for reading the vehicle fault mem-
ory. The fault memory documents errors and
deviations from the theoretical values of the
electronic control units.
The diagnostics connector is in the driver
side footwell area, next to the lever for open-
ing the bonnet, below a cover.
The fault memory should only be read and re-
set by a specialised workshop.
Using a mobile telephone in a vehicle
without c
onnection to an exterior aer-
ial Mobile telephones transmit and receive radio
w
av
e

s also called high-frequency energy,
both when in use and when on stand-by. Sci-
entific studies state that radio waves exceed-
ing certain values may be harmful to the hu- man body. International committees and au-
thorities h

ave established limits and direc-
tives in order to ensure electromagnetic radi-
ation from mobile phones remains within cer-
tain limits that do not endanger health. Nev-
ertheless, there is no conclusive scientific
evidence that wireless telephones are totally
safe.
That is why some experts recommend moder-
ate use of the mobile telephone, and the ap-
pliance of measures to reduce radiation on
the human body.
When a mobile phone not connected to an
exterior aerial is used inside the vehicle, the
electromagnetic radiation may be greater
than if the mobile phone were connected to a
built-in aerial or to another exterior aerial.
If the vehicle is fitted with a suitable hands-
free device that allows the employment of
numerous additional mobile telephone func-
tions with compatible Bluetooth technolo-
gy ®
, it will comply with the legislation in
many countries which only permits the use of
mobile phones inside vehicles using a
hands-free device.
Mobile telephones must be placed in a suita-
ble telephone support or stored safely in the
vehicle. If a support is used for the tele-
phone, it must be securely fastened to the
base plate. The mobile will be secure on the
instrument panel and always within reach of
the driver only by following these procedures. Mobile telephone connection with an exter-
nal aeri
al is carried out subject to the hands-
free device, via the telephone support or by
the Bluetooth ®
connections present in the
mobile telephone and the vehicle.
If the mobile phone is connected to an aerial
incorporated into the vehicle or an exterior
aerial connected to the vehicle, it will help re-
duce the electromagnetic radiation transmit-
ted and the risk to human health. It will also
improve the quality of the connection.
If the phone is used inside the vehicle with-
out the hands-free system, it will not be se-
curely fastened and will not be connected to
the exterior aerial of the vehicle telephone.
Nor will the telephone charge if it is not on
the support. In addition, some calls may
break off and the quality of the connection
will be affected.
Mobile telephones should only be used in-
side the vehicle if they are connected to a
hands-free system. SEAT recommends using
an external aerial should you wish to use a
mobile telephone inside the vehicle.

If the mobile phone is not securely fastened
in pos ition, it

could be sent flying around the
vehicle in the event of sharp braking, sudden
manoeuvres or accident, causing injury. 168

Advice
●
Comp ar
e the distance between the vehicle
wheels and the distance between the guide-
rails of the car wash to prevent damage to the
wheels and tyres!
● Switch off the rain sensor before taking the
vehicl
e to an automatic car wash.
● Compare the height and width of your vehi-
cle w
ith the available height and width when
entering and driving through the car wash.
● Fold in exterior mirrors Electrically retracta-
ble e
xterior mirrors must not be folded in or
out by hand. Always use the electrical power
control.
● To avoid damaging the bonnet paintwork,
res
t the windscreen wipers on the windscreen
after drying the wiper blades. Do not let them
fall!
● Lock the rear lid to prevent it from opening
unexpect
edly while inside the car wash. Washing the vehicle with a high pres-
s
ur
e c

leaner When cleaning the vehicle with a high-pres-
s
ur
e c

leaner, always follow the operating in-
structions for the equipment. Pay special at-
tention to the required pressure of the jet
and the distance between the jet and the ve-
hicle ››› .
K eep a s uit

able distance from soft materials,
such as rubber hoses or insulating material,
and from the parking distance warning sys- tem sensors. The sensors of the parking dis-
tance w

arning system are situated on the rear
bumper ››› .
Do not u
se a no

zzle that sprays the water out
in a direct stream or one that has a rotating
jet for forcing off dirt ››› .
WARNING
The incorrect use of high pressure cleaning
equipment c ou

ld result in permanent dam-
age, visible or invisible, to the tyres or other
materials. This could result in a serious acci-
dent.
● Ensure there is a suitable distance between
the nozzl
e and the tyres.
● Never wash tyres with a concentrated jet or
so-cal
led “dirt blasters”. Even at large spray-
ing distances and short cleaning times, you
may damage the tyres. WARNING
After the vehicle has been washed, the brak-
ing eff ect

will be reduced (and the braking
distance increased) due to moisture (and ice
in winter) on the brakes.
● “Dry the brakes and remove ice” by braking
caref
ully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process. CAUTION
● The wat er t

emperature should not exceed
+60°C (+140°F).
● To avoid damage to the paintwork, do not
wash the
vehicle in full sun.
● To ensure that the system functions well,
the sensors
located on the bumper must be
kept clean and free from ice. When cleaning
with pressure hoses and steam cleaners, the
sensors should be sprayed only briefly. A dis-
tance of 10 cm between the sensors and the
steam / hose nozzle must be observed.
● Do not use a high pressure cleaner to re-
move ic
e or snow from windows
● Washing the vehicle in low temperatures:
When washin
g the vehicle with a hose, do
not direct water into the lock cylinders or the
gaps around the doors or roof. Locks and
seals could freeze! Cleaning windows and exterior mir-

syst
em. The battery could explode.
● To minimise the risk of electric shock and
serious c
onsequences while the engine is
running or starting the engine, note the fol-
lowing:
– Never touch the electrical wiring of the
ignition system. WARNING
In the engine compartment, there are rotat-
ing p ar

ts that could cause serious injury.
● Never place your hands directly on or near
the radi
ator fan. Touching the rotor blades
could seriously harm you. The ventilator
works according to the engine temperature
and could start suddenly even when the igni-
tion is turned off and the key is removed.
● If any work has to be performed when the
engine is
started or with the engine running,
there is an additional, potentially fatal, safety
risk from rotating parts, such as the drive
belts, alternator, radiator fan, etc., as well as
from the high-voltage ignition system. Al-
ways work with the utmost caution.
– Always make sure that no parts of your
body, jewellery, ties, loose clothing and
long hair can be trapped by the rotating
parts of the engine. Before any work, re- move ties and jewellery (necklaces, etc),
tie long h
air b

ack and tie all items of
loose clothing to your body to make sure
that they cannot be trapped by engine
components.
– Take extreme caution when operating the
accelerator and remain attentive. The ve-
hicle could move, even if the handbrake
is applied.
● Always make sure you have not left any ob-
jects, s
uch as cleaning cloths and tools, in
the engine compartment. If any object is left
in the engine compartment, this could cause
malfunctions, engine faults and even a fire. WARNING

● Pull out the dipstick and wipe it on a clean
cloth.
● Rep

lace the dipstick, pushing it in as far as
it wi
ll go. If the dipstick to measure engine oil
has a mark, when you reintroduce it this
mark should slot into the corresponding
groove located on the upper end of the tube.
● Remove the oil dipstick again and check
the engine oil
level.
● After reading the oil level, replace the dip-
stick
in the tube completely. WARNING
Oil could catch fire if it comes into contact
with hot en

gine components. This could lead
to a fire, explosion and severe injuries.
● Always ensure that after topping of oil, the
engine oil
filler cap is correctly tightened.190

Checking and refilling levels
This will avoid engine oil spilling onto hot en-
gine par
t
s when the engine is running. CAUTION
● If the en gine oi

l level is above the area
››› Fig. 168 A do not start the engine. Seek
spec i
alist assistance. Otherwise catalytic
converter and engine damage may occur.
● When refilling or changing service liquids,
ensur
e that you put the liquids into the right
tank. Making a mistake when refilling could
cause serious malfunctions and damage the
engine! For the sake of the environment
The oil level must never be above area A .
Otherw i

se oil can be drawn in through the
crankcase breather and escape into the at-
mosphere via the exhaust system. Engine oil consumption
The consumption of engine oil can be differ-
ent
fr
om one en

gine to another and can vary
during the useful life of the engine.
Depending on how you drive and the condi-
tions in which the vehicle is used, oil con-
sumption can be up to 1 ltr./2000 km. In the
case of new vehicles, the consumption can
exceed this figure over 5,000 kilometres. For
this reason the engine oil level must be checked at regular intervals, preferably when
fillin

g the tank and before a journey.
When the engine is working hard, for in-
stance during sustained high-speed motor-
way cruising in summer or when climbing
mountain passes, the oil level should pref-
erably be kept within area ››› Fig. 168 A .
Topping up engine oil Read the additional information carefully

 page 31.
The engine oil must be changed regularly ac-
cording to the specifications of the Mainte-
nance Programme.
Due to the problems linked with disposing of
used oil and the need for suitable tools and
special knowledge, always visit a specialised
workshop to have the engine oil and filter
changed. SEAT recommends taking your car
in for technical service.
Detailed information on the service intervals
is shown in the Maintenance Programme.
Engine oil additives make new oil darker after
the engine has been running for a short peri-
od. This is normal and does not mean more
frequent oil changes are required. WARNING
Only change the engine oil yourself if you
hav e the s

pecialist knowledge required!
● Before opening the bonnet, read and ob-
serve the w
arnings ››› page 187.
● Wait for the engine to cool down. Hot oil
may
cause burn injuries.
● Wear eye protection to avoid injuries, such
as ac
id burns, caused by splashes of oil.
● When removing the oil drain plug with your
finger
s, keep your arm horizontal to help pre-
vent oil from running down your arm.
● Wash your skin thoroughly if it comes into
contact
with engine oil.
● Engine oil is poisonous! Used oil must be
stor
ed in a safe place out of the reach of chil-
dren. CAUTION
No additives should be used with engine oil.
