›››  page 16 CAUTION
If the ignition is switched off with the wind-
screen wipers active, they complete their wipe before returning to the rest position.
Ice, snow and other obstacles on the wind-
screen may damage the wiper and the wind-
screen wiper motor.
● If necessary, remove snow and ice from the
windscreen wipers before starting your jour-
ney.
● Carefully lift the frozen windscreen wipers
from the glass. SEAT recommends a de-icer
spray for this operation.
● Do not switch on the windscreen wipers if
the windscreen is dry. Cleaning with the
windscreen wipers while dry can cause dam-
age.
● In icy conditions, always check that the
wiper blades are not frozen to the glass be-
fore using the wipers. In cold weather, it may
help to leave the vehicle parked with the wip-
ers in service position ››› page 230. Note
● The windscreen and window wipers only
function when the ignition is switched on and
the bonnet or rear lid, respectively, are
closed.
● The interval wipe speed varies according to
the vehicle speed. The faster the vehicle is
moving, the more often the windscreen is
cleaned.
● The rear wiper is automatically switched on
when the windscreen wiper is on and the car
is in reverse gear. 102

Operation
●
While you are selecting a gear and the vehi-
cle is stopped with the engine running, do
not accelerate. Failure to follow this instruc-
tion could result in an accident.
● As a driver you should never leave your ve-
hicle if the engine is running and a gear is en-
gaged. If you have to leave your vehicle while
the engine is running, you must apply the
handbrake and engage the parking lock (P).
● To avoid accidents, apply the handbrake
and put the selector lever in position P before
opening the bonnet and working on the vehi-
cle with the engine running. Please always
observe the important safety warnings
››› page 198, Work in the engine compart-
ment. Note
● If the selector lever is moved accidentally
to N when driving, release the accelerator and
let the engine speed drop to idling before se-
lecting gear range D or S again.
● Should the power supply to the selector
lever be interrupted in position P, the selector
lever will be locked. If this should happen the
manual release can be used ››› page 229. Selector lever lock
Fig. 143
Selector lever lock. The selector lever lock prevents gears from
being engaged inadvertently, so that the ve-
hicle is not set in motion unintentionally.
The selector lever lock is released as follows:
– Switch the ignition on.
– Press the brake pedal and at the same time
pr e
ss in the interlock button.
Automatic selector lever lock
With the ignition switched on, the selector
lever is locked in the positions P and N. The
brake pedal must be pressed to release the
lever while pressing the release button if the
selector lever is in the position P. As a re-
minder for the driver, with the lever in posi-
tions P or N the following message will be
shown on the display: When stationary, apply footbrake while se-
lecting a gear.
The selector lever lock only works if the vehi-
cle is stationary or driving at speeds up to 5
km/h. At higher speeds the selector lever
lock in the N position is disengaged automat-
ically.
The selector lever lock is not engaged if the
selector lever is moved quickly through posi-
tion N (e.g. when shifting from R to D). This
makes it possible, for instance, to rock the
vehicle “backwards and forwards” if it is
stuck. The selector lever lock engages auto-
matically if the brake pedal is not depressed
and the lever is in position N for more than
about two seconds.
Interlock button
The interlock button on the selector lever
handle prevents the driver from inadvertently
engaging certain gears. Press the button in
to disengage the selector lever lock. The se-
lector lever positions in which the interlock
button has to be pressed are shown in the il-
lustration, highlighted in colour ››› Fig. 143.
Safety

interlock for ignition key
Once the ignition has been turned off, the
key may be removed only if the gear selector
is in position P. While the key is not in the ig-
nition, the selector lever is locked in position
P.

Checking and refilling levels
●
Take care not to cause short circuits in the
electrical system, especially when working
on the battery.
● If working inside the engine compartment,
remember that, even when the ignition is
switched off, the radiator fan may start up au-
tomatically, and therefore there is a risk of in-
jury.
● Never cover the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pansion tank when the engine is hot. The
cooling system is under pressure.
● Protect face, hands and arms by covering
the cap with a large, thick rag to protect
against escaping coolant and steam.
● If it is necessary to work in the engine com-
partment while the engine is running, the ro-
tating components (for example, poly-V belt,
alternator, radiator fan) and the high voltage
ignition system are an additional hazard.
● Observe the following additional warnings
if work on the fuel system or the electrical
system is necessary:
– Always disconnect the battery from the
on-board network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguish-
er immediately available. CAUTION
When topping up fluids make sure the correct
fluid is put into the correct filler opening, oth-
erwise this can cause serious malfunctions or
engine damage. For the sake of the environment
Inspect the ground underneath your vehicle
regularly so that any leaks are detected at an
early stage. If you find spots of oil or other
fluids in the area where it was parked, have
your vehicle inspected at the workshop. Note
On right-hand drive vehicles* some of the
containers/reservoirs mentioned below are
located on the other side of the engine com-
partment. Opening the bonnet
Read the additional information carefully
›››  page 10
The bonnet is released from inside the vehi-
cle.
Check that the windscreen wiper arms are
not unfolded. Otherwise the paint may be
damaged.
The bonnet can only be unlocked when the
driver door is open. WARNING
Never open the bonnet if you see steam or
drips of coolant being released from the en-
gine compartment. Failure to comply could
result in burns. Wait until no steam or coolant
can be seen before opening the bonnet. Closing the bonnet
–
Slightly lift the bonnet.
– Release the bonnet stay before pressing it
back into its support.
– Carefully close the bonnet.
– Press the bonnet down until it locks into
place.

Engine oil specification ››› page 200. WARNING
Oil is highly inflammable! Ensure that no oil
comes into contact with hot engine compo-
nents when topping up. CAUTION
If the oil level is above the area A do not
start the engine. This could result in damage
to the engine and catalytic converter. Contact
a specialised workshop. 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 at-
mosphere via the exhaust system. Changing engine oil
The engine oil must be changed at the inter-
vals given in the service schedule.
We recommend that you have the engine oil
changed by a Technical Service.
The oil change intervals are shown in the
Maintenance Programme.
WARNING
Only change the engine oil yourself if you
have the specialist knowledge required!
● Before opening the bonnet, read and ob-
serve the warnings ››› page 198.
● Wait

for the engine to cool down. Hot oil
may cause burn injuries.
● Wear eye protection to avoid injuries, such
as acid burns, caused by splashes of oil. ●
When removing the oil drain plug with your
fingers, 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
stored in a safe place out of the reach of chil-
dren. CAUTION
No additives should be used with engine oil.
This could result in engine damage. Any dam-
age caused by the use of such additives
would not be covered by the factory warranty. For the sake of the environment
● Because of disposal problems and the spe-
cial tools and specialist knowledge required,
we recommend that you have the engine oil
and filter changed by a Technical Service.
● Never pour oil down drains or into the
ground.
● Use a suitable container when draining the
used oil. It must be large enough to hold all
the engine oil. 202

Checking and refilling levels
Check the water level in the windscreen
washer reservoir regularly and top up as re-
quired.
The container for the windscreen washer con-
tains the cleaning fluid for the windscreen,
the rear window and the headlight washer
system*.
● Open the bonnet  ››› page 198.
● The windscreen washer reservoir is marked
with the symbol  on the cap.
● Chec k
there is enough windscreen water in
the reservoir.
Recommended windscreen wipers
● For the hottest seasons we recommend
summer G 052 184 A1 for clear glass. Propor-
tions of the mixture in the washer fluid tank:
1:100 (1 part concentrate per 100 parts wa-
ter).
● All year round, G 052 164 A2 for clear
glass. Approximate proportion of the winter
mixture, up to -18°C (0°F): 1:2 (1 part con-
centrate per 2 parts water); otherwise, a 1:4
proportion of mixture in the washer fluid
tank.
Top-up quantities
The reservoir holds approximately 3 litres in
versions without headlight washer and 5 li-
tres in versions with headlight washer. WARNING
If the water from the windscreen washer does
not contain enough anti-freeze, it may freeze
on the windscreen and rear window, reducing
forward and rear visibility.
● In winter, ensure the windscreen washer
contains enough anti-freeze.
● In cold conditions, you should not use the
windscreen washer system unless you have
warmed the windscreen with the ventilation
system. The antifreeze could freeze on the
windscreen and reduce visibility. WARNING
Never mix an unsuitable antifreeze or other
similar additives with the windscreen washer
water. A greasy layer may be formed on the
windscreen which will impair visibility.
● Use clean water with a window cleaner rec-
ommended by SEAT.
● If necessary, add a suitable antifreeze to
the water in the reservoir. CAUTION
● Do not mix cleaning products recommen-
ded by SEAT with other products. This could
lead to flocculation and may block the wind-
screen washer jets.
● When topping up service fluids, make abso-
lutely certain that you fill the fluids into the
correct reservoirs. Using the wrong fluids could cause serious malfunctions and engine
damage!
● Not having windscreen wiper fluid reduces
visibility through the windscreen, and leads
to loss of visibility in headlights in models
with headlight washer. Battery

the negative pole of the battery. ●
Switch off all electrical devices before re-
connecting the battery. Reconnect first the
positive cable and then the negative cable.
Never reverse the polarity of the connections.
This could cause an electrical fire.
● Ensure that the vent hose is always connec-
ted to the battery.
● Never use damaged batteries. This could
cause an explosion! Replace a damaged bat-
tery immediately. CAUTION
● Never disconnect the battery if the ignition
is switched on or if the engine is running.
This could damage the electrical system or

Important: Before you charge the battery
make sure you read the manufacturer's in-
structions for using the battery charger. WARNING
Never charge a battery that has frozen: re-
place battery! Failure to do so may lead to an
explosion. Note
Use only the terminals in the engine compart-
ment to charge the battery. Replacing the battery
The new battery should have the same speci-
fications (amperage, load and voltage) as the
used battery.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy
››› page 191.
The power management function ensures
that the battery is charged much more effi-
ciently than on vehicles without a power
management system. To maintain this func-
tion after replacing the battery, we recom-
mend that the replacement battery used is of
the same make and type as the original fitted
battery. To make proper use of the power
management function after the battery has
been changed, have the battery coded to the
power management mode at a specialised
workshop. CAUTION
● Some vehicles, for example those with the
Start-Stop system* are fitted with a special
battery (AGM-type or EFB-type battery). If any
other type of battery is fitted, the Start-Stop
function may be considerably reduced and
the vehicle may not stop on repeated occa-
sions.
● Make sure that the vent hose is always at-
tached to the original opening on the side of
the battery. Gases or battery acid can other-
wise escape and possibly cause damage. ●
The battery holder and clamps must always
be correctly secured.
● Before starting any work on the battery, al-
ways observe the warnings listed under
››› page 206, Important safety warnings for
handling a vehicle battery .
● Do not forget to replace the battery cover-
ings, where applicable. It is a protection for
high temperatures. This in turn extends the
vehicle service life. For the sake of the environment
 Batteries contain toxic substances includ-
in g s

ulphuric acid and lead. They must be
disposed of appropriately and must not be
disposed of with ordinary household waste.
Make sure disconnected batteries cannot tip
over. Sulphuric acid could be spilt! 207
