›››  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.

Operation
Note
The Official Service or a specialist workshop
can tell you if your vehicle is equipped with
this system. Start-Stop system*
Description and operation The Start-Stop system helps save fuel and re-
duce CO
2 emissions.
In Start-Stop mode, the engine will automati-
cally switch off when the vehicle stops, when
stopping at traffic lights for example. The ig-
nition remains switched on during the stop-
ping phase. The engine automatically
switches back on when required.
As soon as the ignition is switched on, the
Start-Stop function is automatically activa-
ted.
Basic requirements for the Start-Stop mode ● The driver door must be closed.
● The driver must have their seat belt fas-
tened.
● The bonnet must be closed.
● The vehicle must have travelled at more
than 4 km/h (2 mph) since the last stop.
● The vehicle cannot be towing a trailer. WARNING
● Never switch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered under warranty. More force may also be
needed to turn the steering wheel or to brake.
As you cannot steer and brake in the normal
manner, there is a greater risk of accidents
and serious injury.
● Never remove the key from the ignition if
the vehicle is in motion. Otherwise, the steer-
ing could lock making it impossible to steer
the vehicle.
● To avoid injury, make sure that the Start-
Stop system is switched off when working in
the engine compartment ››› page 149. CAUTION
The Start-Stop system must always be
switched off when driving through flooded
areas ››› page 149. Stop/Start the engine
Vehicles with a manual gearbox
– When the vehicle is stopped, put it into
neutral and release the clutch pedal. The
engine will switch off. The warning lamp 
will appear on the instrument panel dis-
play. –
When the clutch pedal is pressed the en-
gine will 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 keep the brake pedal pressed
down with your foot. The engine will switch
off. The warning lamp  will appear in the
di s
play.
– When you take your foot off the brake pedal
the engine will start up again. The warning
lamp will switch off.
Additional information related to the
automatic 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.
Change from position D to P to prevent the
engine from accidentally starting when
changing and passing by position R.

Advice
Automatic car washes
Before going through a car wash, be sure to
take the usual precautions such as closing
the windows and roof. If the vehicle has spe-
cial accessories such as spoilers or a roof
rack or two-way radio aerial, etc., it is advisa-
ble to consult the car wash tunnel operator.
It is best to use a car wash without revolving
bristles if possible.
Washing the vehicle with a high pressure
cleaner
When washing the vehicle with a high-pres-
sure cleaner, always follow the operating in-
structions for the equipment. This applies
particularly to the operating pressure and the
spraying distance . Do not hold the nozzle too
c lo
se to soft materials such as rubber hoses
or seals. The same applies to the parking aid
sensors*, which are located in the rear bump-
er.
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.
Washing the car by hand
When washing the car by hand, use plenty of
water to soften the dirt first, and rinse off as
well as possible.
Then clean the vehicle with a soft sponge,
glove
or brush using only slight pressure.
You should start on the roof and work down. Special car
soap
should only be used for very
persistent dirt.
Rinse the sponge or glove thoroughly and of-
ten.
Wheels, sills and similar should be cleaned
last. Use a second sponge for this. WARNING
● The vehicle should only be washed with the
ignition switched off. Failure to follow this in-
struction could result in an accident.
● Do not clean the underside of chassis, the
inside of wheel arches or wheel trims without
protecting your hands and arms. You may cut
yourself on sharp-edged metal parts. Other-
wise, there is a risk of sustaining cuts.
● When washing the car during the winter
season: water and ice in the brake system
can reduce braking effectiveness: risk of acci-
dent! CAUTION
● Do not wash the vehicle in direct sunlight –
otherwise the paint can be damaged.
● Do not use sponges, abrasive household
sponges or similar to clean insect remains.
This could damage the surface.
● Clean off stubborn dirt (insects, etc.) from
the headlights at regular intervals, for in-
stance when filling the fuel tank. The head-
lights should only be washed with water, do not wipe them with a dry cloth or sponge. It
is best to use soapy water.
● Never wash tyres with a jet that sprays the
water out in a direct stream. This could dam-
age the tyres even if the spray is kept at a
distance and only used for a very short time.
● Before washing the vehicle in an automatic
car wash, please make sure to retract the ex-
terior mirrors to prevent them from being
damaged. Electrically retractable exterior
mirrors must not be folded in or out by hand,
always use the electrical power control. CAUTION
● Before washing the vehicle in an automatic
car wash, please proceed as follows to lock
the wiper arms so that they are not moved to-
wards the top of the windscreen:
–the bonnet must be closed.
– switch the ignition on and off.
– press the windscreen wiper lever forward
briefly (windscreen washer function).
This will lock the wiper arms. For the sake of the environment
The car should only be washed in special
wash bays. These areas are prepared to pre-
vent oily water from getting into the public
drains. In some places, washing vehicles out-
side the areas intended for this purpose is
prohibited. 184

Care and maintenance
Camera sensors and lenses ●
Use a small brush to remove snow and a
de-icer spray to remove ice.
● Clean the sensors with a solvent-free prod-
uct and a soft, dry cloth.
● Moisten the camera lens using a standard
alcohol-based glass cleaning agent and
clean the lens with a dry cloth. In the active
lane assist*, the area in front of the lens is
norm al
ly cleaned with the windscreen wash-
er. CAUTION
● When you clean the vehicle with a pressure
washer:
–Stay a suitable distance from the sensors
on the front and rear bumpers.
– Do not clean the camera lenses or sur-
rounding area with the pressure washer.
● Never use warm or hot water to remove
snow and ice from the reverse camera lens,
as it could crack the lens.
● Never use abrasive cleaning agents on the
lens. Care and polishing
Care
Waxing protects the paintwork. It is time to
apply a
coat of good wax when water no lon- ger forms droplets
and rolls off the clean
paintwork.
Even if a wax solution is used regularly in the
vehicle washing tunnel, it is advisable to pro-
tect the paint with a hard wax coating at least
twice a year.
In the summer, you will find it is much easier
to remove dead insects (which accumulate
on the bumper and the front of the bonnet) if
the car has been treated with care products
recently .
P o

lishing
Polishing is only necessary if the paint has
lost its shine, and the gloss cannot be
brought back by putting on wax.
If the polish does not contain wax, a wax
product should be applied after polishing. CAUTION
● Do not use polishes and hard wax on pain-
ted parts with a matt finish or on plastic
parts.
● Do not apply paint polishes to the side trim
that runs around the panoramic roof and ends
on the windscreen. However, it can be treated
with hard wax. Trims
In respect for the environment, the silver-
plated trims on the body are made of pure
aluminium (they do not contain chrome).
Dirt or marks on the trim mouldings should
be removed with a cleaning product with a
neutr
a

l PH (do not use a chrome cleaner).
Body polish is also unsuitable for use on trim
mouldings. The intensive cleaning fluids of-
ten used before the car goes into a car wash
may contain alkaline substances, which can
cause dull or milky patches when they dry
out.
SEAT Official Services carry stocks of cleaning
products which have been tested for use on
your vehicle and are not harmful to the envi-
ronment.
Plastic parts Plastic parts are cleaned with a power wash-
er. If this is not sufficient, plastic parts
should only be treated with a special solvent-
free
plastic cleaning agent
. Do not
u
se paint-
work cleaners, polishes or wax on plastic
parts.

W ork
in the engine compartment Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment
(e.g. when checking and refilling fluids). Al-
ways observe the warnings listed below and
follow all general safety precautions. The en-
gine compartment of the vehicle is a poten-
tially hazardous area
››› . WARNING
● Switch the ignition off.
● Remove the ignition key.
● Apply the handbrake.
● If the vehicle has a manual gearbox, place
the lever in neutral; if it has an automatic
gearbox, place the selector lever in position
P.
● Wait for the engine to cool down.
● Keep children away from the engine com-
partment.
● Never spill liquids used for vehicle opera-
tion on the engine compartment, as these
may catch fire (e.g. the antifreeze in coolant). 198

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.
