In the engine compartment
WARNING (Continued)
● Never open the bonnet if you see steam or coolant escaping from the
engine compartment. Hot vapours and coolant can cause serious burns.
Always wait until you cannot see or hear the sound of steam or coolant
coming from the engine compartment.
● Always allow the engine to cool down before opening the bonnet.
● Contact with hot elements of the engine and the exhaust system can
cause burns.
● Once the engine has cooled, follow the instructions below before
opening the bonnet:
–Engage the handbrake and place the gear selector lever in P or the
gear stick in neutral.
– Remove the key from the ignition.
– Keep children away from the engine compartment and never leave
them unsupervised.
● When the engine is warm or hot, the cooling system is pressurised.
Do not unscrew the cap on the coolant expansion tank when the engine
is hot. Otherwise, coolant may spray out under pressure causing burns
and serious injury.
–After cooling, carefully and slowly unscrew the cap anticlockwise,
gently pressing down on it.
– Always protect your face, hands and arms from hot coolant and
steam using a large, thick cloth.
● When refilling liquids, avoid spilling them on parts of the engine and
the exhaust system. Spilled liquids could cause a fire.WARNING
The high voltages of the electrical system can give electric shocks as well
as causing burns and serious injury and possibly even death!
● Never cause short circuits in the electrical system. The battery could
explode.
● To minimise the risk of electric shock and serious consequences
while the engine is running or starting the engine, note the following:
–Never touch the electrical wiring of the ignition system.
WARNING
In the engine compartment, there are rotating parts that could cause se-
rious injury.
● Never place your hands directly on or near the radiator fan. Touching
the rotor blades could seriously harm you. The ventilator works accord-
ing to the engine temperature and could start suddenly even when the ig-
nition 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 the rotating parts, such as the drive belts, alternator, radiator fan
etc as well as from the high-voltage ignition system. Always 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 en-
gine. Before any work, remove ties and jewellery ( necklaces, etc), tie
longhair back 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 vehicle could move, even if the handbrake is applied.
● Always make sure you have not left any objects, such as cloths or
tools, in the engine compartment. If any object is left in the engine com-
partment, this could cause malfunctions, engine faults and even a fire.

Additional information and warnings:
● ⇒ Booklet Maintenance Programme
● Working in the engine compartment ⇒ page 180
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
Incorrectly handling engine oil can cause injury and serious burns.
● Always protect your eyes when handling engine oil.
● Oil is toxic and must be kept out of the reach of children.
● Engine oil must only be kept closed in its original container. The same
applies to use oil until it has been disposed of.
● Never store engine oil in empty food containers or bottles as other
people may accidentally drink it.
● Regular contact with engine oil can be bad for the skin. If you come
into contact with engine oil, wash your skin with soap and water.
● With the engine running, the engine oil gets extremely hot and can
cause severe skin burns. Always wait until the engine has fully cooled.
For the sake of the environment
Similar to the other service liquids, spilled engine oil can be bad for the en-
vironment. Collect any spilt fluids in suitable containers and dispose of in
accordance with legislation and with the utmost respect for the environ-
ment. Warning and control lamps

● Open the bonnet ⇒ page 180.
● The engine oil filler mouth can be recognised by the symbol on the
cap ⇒ Fig. 112 and the dipstick by its coloured handle.
Check the engine oil level
● Pull out the dipstick and wipe it on a clean cloth.
● Replace the dipstick, pushing it in as far as it will 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 dipstick again and check the engine oil level ⇒ table on
page 187.
● After reading the oil level, replace the dipstick in the tube completely.
Engine oil topping up ranges
Fig. 111Operations required depending on the engine oil topping
up level:
Area ADo not top up oil
⇒ .Area BYou can add oil, but keep the level in this zone.
Area COil
must be added. After topping up the oil level should be
in area B.
Adding oil after checking the level
Only add engine oil in small quantities and in steps.
●
Unscrew the cap from engine oil filler mouth on the cylinder head
⇒ Fig. 112. If you are not sure where the cap is, request help from a special-
ist.
● Only refill using approved SEAT engine oil in small quantities (no more
than 0.5 ltr) ⇒ page 185.
● To avoid adding too much oil, each time you add a quantity, wait until
the oil has flowed into the crankcase so that it can be measured with the
dipstick.
● Check the oil level before adding any more oil. Do not top up with too
much engine oil ⇒
. ●
When the oil level is in at least the ⇒ Fig. 111 B
zone, insert the dip-
stick into the tube fully to avoid engine oil escaping when the engine is run-
ning.
● After topping up the oil, ensure that the cap is screwed on to the filler
mouth correctly.
WARNING
Oil could catch fire if it comes into contact with hot engine components.
This could lead to a fire, explosion and severe injuries.
● Always ensure that after topping of oil, the engine oil filler cap is cor-
rectly tightened. This will avoid engine oil spilling onto hot engine parts
when the engine is running.
CAUTION
● If the engine oil level is above the area A do not start the engine. You
should obtain professional assistance. Otherwise catalytic converter and
engine damage may occur.
● When refilling or changing service liquids, ensure that you put the liq-
uids into the right tank. Making a mistake when refilling could cause seri-
ous malfunctions and damage the engine!
For the sake of the environment
The oil level must never be above area A. Otherwise oil can be drawn in
through the crankcase breather and escape into the atmosphere via the ex-
haust system.
Engine oil consumption
The consumption of engine oil can be different from one engine to another
and can vary during the useful life of the engine.

on the expansion tank ⇒ Fig. 113.
● If the level is below the “MIN” mark, top up with coolant. When the en-
gine is hot it may be slightly above the marked area.
Topping up the engine coolant level
● Always protect your face, hands and arms from hot coolant and steam
using a large, thick cloth over the coolant expansion tank cap.
● Remove the cap very carefully ⇒
.
● Only refill using new engine coolant according to SEAT specifications
(⇒ page 190) ⇒
.
● The engine coolant level should be between the marks on the coolant
expansion tank ⇒ Fig. 113. Do not exceed the top level of the marked area
⇒
.
● Screw on the cap tightly.
● If, the event of an emergency, you have no coolant that is compliant to
the required specifications ( ⇒ page 190), never use another type of addi-
tive. Instead, first top up with distilled water ⇒
only. Then re-establish
the correct proportion of the mixture with the correct additive as soon as
possible ⇒ page 190.

Vehicle care and maintenance
CAUTION
To prevent damage to the vehicle, please observe the following before en-
tering an automatic car wash :
● Compare the distance between the vehicle wheels and the distance be-
tween the guide-rails of the car wash to prevent damage to the wheels and
tyres!
● Switch off the rain sensor before taking the vehicle to an automatic car
wash.
● Compare the height and width of your vehicle with the available height
and width when entering and driving through the car wash!
● Fold in exterior mirrors Electrically retractable exterior mirrors must NOT
be folded in or out by hand. Always use the electrical power control.
● To avoid damaging the bonnet paintwork, rest 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 unexpectedly while inside
the car wash.
Washing the vehicle with high pressure cleaning apparatus
When cleaning the vehicle with a high-pressure cleaner, always follow the
operating instructions for the equipment. Pay special attention to the re-
quired pressure of the jet and the distance between the jet and the vehicle
⇒
.
Keep a suitable distance from soft materials, such as rubber hoses or insu-
lating material, and from the parking distance warning system sensors. The
sensors of the parking distance warning system are situated on the rear
bumper ⇒
.
Do not use a nozzle 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 could result in
permanent damage, visible or invisible, to the tyres or other materials.
This could result in serious accident.
● Ensure there is a suitable distance between the nozzle and the tyres.
● Never wash tyres with a concentrated jet or so-called “dirt blasters”.
Even at large spraying distances and short cleaning times, you may dam-
age the tyres.
WARNING
After the vehicle has been washed, the braking effect 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 carefully. Ensure that you
are not endangering other road-users or breaking traffic regulations in
the process.
CAUTION
● The temperature of the water must not be above +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
distance of 10 cm between the sensors and the steam / hose nozzle must
be observed.
● Do not use a high pressure cleaner to remove ice or snow from windows
● Washing the vehicle in low temperatures: When washing the vehicle
with a hose, do not direct water into the lock cylinders or the gaps around
the doors, rear lid, or sunroof. Locks and seals could freeze!
