Steering wheel lock
– To lock the steering wheel, remove the key from the ignition and
turn the wheel until it locks. In vehicles with the automatic gear-
box*, the selector lever must be in the position P in order to re-
move the key.
– To unlock the steering wheel, insert the key into the ignition
and simultaneously turn the key (in the direction of the arrow)
and the steering wheel.
Warning: If the steering wheel cannot be turned, this is because
the steering wheel lock is activated. Switching the ignition on/off, preheating
–
Turn the ignition key to position 2
to switch on the ignition.
– Turn the ignition key to position 1
to switch off the ignition.
Preheating is produced in Diesel vehicles  when the ignition is
switched on.
Starting up the engine
– Manual gearbox: Press the clutch pedal all the way down and
move the gearbox lever into neutral.
– Automatic gearbox : Press the brake pedal and move the selec-
tor lever to position P or N.
– Turn the ignition key to position 3
. The key returns to position
2 automatically. Do not press the accelerator.
Diesel engines can take a few seconds longer than usual to start
on cold days. Therefore the clutch pedal (manual gearbox) or the
brake pedal (automatic gearbox) must remain pressed until the en-
gine starts up. During preheating, the warning lamp  remains lit.
The preheating time depends on the coolant and exterior tempera-
tures. When the engine is at operating temperature or at outside
temperatures above +8 °C (46 °F) the warning lamp  will only
light up for about one second. This means that the engine starts
immediately.
If the engine does not immediately start up, interrupt the starting process
and try again after 30 seconds. To start the engine again, return the key to
position 1

lever is not in the position P when the driver door is opened. Put the selec-
tor lever in position P; otherwise the vehicle can roll away.
Ignition is switched onThis driver message is displayed and a buzzer is sounded when the driver
door is opened with the ignition switched on.
WARNING
● Never run the engine in confined spaces, as the exhaust gases are
poisonous.
● Never remove the key from the ignition if the vehicle is in motion.
Otherwise, the steering could suddenly lock, making it impossible to
steer the vehicle: risk of accident!
● Always take the key with you when you leave the vehicle. This is par-
ticularly important if there are children in the vehicle, as they might oth-
erwise be able to start the engine or use power-operated equipment (e.g.
the electric windows), which could cause injuries.
CAUTION
Avoid high engine speeds, full throttle and extreme load conditions until
the engine has reached its normal operating temperature, otherwise this
can damage the engine.
For the sake of the environment
Do not warm up the engine by running it with the car stationary. You should
drive off as soon as you start the engine. This will help avoid unnecessary
exhaust emissions.
Note
● If it is difficult to turn the ignition key to the position 1, turn the steer-
ing wheel to both sides to release the steering lock.
● When starting from cold, the engine may be a little noisy for the first few
seconds until oil pressure has built up in the hydraulic valve lifters. This is
quite normal, and no cause for concern.
● If the vehicle battery is disconnected and reconnected, the key must re-
main in the position 1
for around 5 seconds before starting up.
● Vehicles with automatic gearbox: After switching off the ignition, you
can only remove the ignition key if the selector lever is in position “P” (park-
ing lock). Next, the selector lever is locked. 

.
Engaging the steering wheel lock
Important: selector lever (automatic gearbox*) must be in position
P.
– Remove the key from the ignition in position 1
⇒ Fig. 86 ⇒ .
– Turn the steering wheel until you hear it engage.
Possible vehicle theft is prevented with the steering lock engaged.
WARNING
● Never switch the engine off until the vehicle is stationary. The brake
servo and power steering functions will not be completely covered 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 steering could lock making it impossible to steer the vehi-
cle.
● Always take the ignition key with you whenever you leave the vehicle,
even temporarily. This is particularly important if there are children in
the vehicle, as they might otherwise be able to start the engine or use
power-operated equipment (e.g. the electric windows), which could
cause injuries.
CAUTION
If the engine has been running under high load for a long time, there is a
risk of heat building up in the engine compartment after the engine has
been switched off; this could cause engine damage. For this reason, you
should idle the engine for approx. 2 minutes before you switch it off.
Note
● After the engine is switched off the radiator fan may run on for up to 10
minutes, even if the ignition is switched off. It is also possible that the fan
turns itself on once more if the coolant temperature increases due to the
heat accumulated in the engine compartment or due to its prolonged expo-
sure to solar radiation.
● If the vehicle is stopped and the Start-Stop system* switches off the en-
gine, the ignition remains switched on. Make sure that the ignition is
switched off before leaving the vehicle, otherwise the battery could dis-
charge. 
Kick-down
The kick-down feature allows maximum acceleration to be
reached. If the eco*
⇒ page 172 mode has been selected in SEAT Drive Mode*, and
the accelerator is pressed beyond a hard point, the engine power is auto-
matically controlled to give your vehicle maximum acceleration.
WARNING
Please note that if the road surface is slippery or wet, the kick-down fea-
ture could cause the driving wheels to spin, which could result in skid-
ding.

–Apply the handbrake.
– Select first gear.
– Switch the engine off and remove the key from the ignition. Turn
the steering wheel slightly to engage the steering lock.
– Always take you keys with you when you leave the vehicle ⇒ 
.
Additional notes on parking the vehicle on gradients:
Turn the steering wheel so that the vehicle rolls against the kerb if it started
to roll.
● If the vehicle is parked facing downhill, turn the front wheels so that
they point towards the kerb .
● If the vehicle is parked facing uphill, turn the front wheels so that they
point away from the kerb .
● Secure the vehicle as normal by applying the handbrake firmly and se-
lecting first gear.
WARNING
● Take measures to reduce the risk of injury when you leave your vehi-
cle unattended.
● Never park where the hot exhaust system could ignite inflammable
materials, such as dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in the vehicle when it is
locked. They would be unable to open the vehicle from the inside, and
could become trapped in the vehicle in an emergency. In the event of an
emergency, locked doors will delay assistance to vehicle occupants.
● Never leave children alone in the vehicle. They could set the vehicle
in motion, for example, by releasing the handbrake or the gearbox lever.
● Depending on weather conditions, it may become extremely hot or
cold inside the vehicle. This can be fatal.
 Hill hold assist*
The Hill hold assist facilitates moving off when driving up-
hill.
Important: the driver door must be closed, the seat belt fastened and the
engine running.
The system is activated when you press and hold the brake pedal for a few
seconds.
To prevent the vehicle from rolling backwards when moving off, the brake
force will remain for a moment after releasing the brake pedal. This short
space of time is enough to start the vehicle with ease.
WARNING
● The smart technology included in the Hill hold assist cannot defy the
laws of physics. Do not let the extra convenience afforded by the Hill hold
assist tempt you into taking any risks when driving.
● The Hill hold assist cannot maintain the vehicle stationary on a slope
in all situations (e.g. on slippery or icy ground).
● If you do not start the vehicle immediately after taking your foot off
the brake pedal, the vehicle may start to roll back under certain circum-
stances. Depress the brake pedal or use the handbrake immediately.
● If the engine stalls, depress the brake pedal or use the handbrake im-
mediately.
● If you are moving off on a slope in stop-and-go traffic, press and hold
the brake pedal for a few seconds before driving off. This will prevent the
vehicle from rolling back unintentionally.
Note
The SEAT Official Service or a specialised workshop can tell you if your vehi-
cle is equipped with the Hill hold assist. 

● The driver must have their seat belt fastened.
● 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 vehicle is stationary. The brake
servo and power steering functions will not be completely covered 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 steering could lock making it impossible to steer the vehi-
cle.
● Always take the ignition key with you whenever you leave the vehicle,
even temporarily. This is particularly important if there are children in
the vehicle, as they might otherwise be able to start the engine or use
power-operated equipment (e.g. the electric windows), which could
cause injuries.
● To avoid injury, make sure that the Start-Stop system is switched off
when working in the engine compartment ⇒ page 152.
CAUTION
The Start-Stop system must always be switched off when driving through
flooded areas ⇒ page 152. 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 display.
– When the clutch pedal is pressed the engine 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 display.
– 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 lever 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 press-
ed, or another 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. 

156Driving
The selector lever lock only works if the vehicle is stationary or driving at
speeds up to 5 km/h (3 mph). At higher speeds the selector lever lock in
the N position is disengaged automatically.
The selector lever lock is not engaged if the selector lever is moved quickly
through position 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 automatically if the brake pedal is not de-
pressed 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 selector lever positions in which the interlock button
has to be pressed are shown in the illustration, highlighted in colour
⇒  Fig. 90.
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 ignition, the selec-
tor lever is locked in position P.
Note
● If the selector lever lock does not engage, there is a fault. The transmis-
sion is interrupted to prevent the vehicle from accidentally moving. Follow
the procedure below in order for the selector lever lock to engage again:
● >With a 6-speed gearbox: press the brake pedal and release it again.
● >With a 7-speed gearbox: press the brake pedal. Move the selector lever
to position P or N and subsequently engage a gear.
● Despite a gear being engaged, the vehicle does not move forwards or
back. Proceed to the next mode: ●
When the vehicle does not move in the required direction, the system
may not have the gear range correctly engaged. Press the brake pedal and
engage the gear range again.
● If the vehicle still does not move in the required direction, there is a sys-
tem malfunction. Seek specialist assistance and have the system checked. 
Driving tips
The gearbox changes gear ratios automatically as the vehi-
cle moves.
The engine can only start with the selector lever in the position P or
N. At low temperatures, below -10 °C (50 °F), the engine can only
start with the selector lever in the position P.
Starting the vehicle
– Press and hold the brake pedal.
– Press and hold the interlock button (the button in the selector
lever handle), move the selector lever to the desired position,
for instance D ⇒  page 154, and release the interlock button.
– Wait for the gearbox to engage the gear (a slight movement can
be felt).
– Release the brake and press the accelerator ⇒ 
.
Stopping briefly
– Apply the foot brake to hold the vehicle when stationary (for in-
stance at traffic lights). Do not press the accelerator. 

202Care and cleaning
Care of the vehicle interior
Radio display/Easy Connect* and control panel*
The display can be cleaned with a soft cloth and a professionally available
“LCD cleaner”. Moisten the cloth with a small amount of the cleaning fluid.
The Easy Connect control panel* should first be cleaned with a brush so
that no dirt goes into the device or between the keys and housing. Next, we
recommend cleaning the Easy Connect control panel* using a cloth damp-
ened with water and washing-up liquid.
CAUTION
● To avoid scratching the screen, do not wipe the display with a dry cloth.
● To avoid damage, ensure that no liquid goes into the Easy Connect con-
trol panel*. 
Plastic and leatherette parts
Plastic parts and leatherette can be cleaned with a damp cloth. If this is not
sufficient, plastic parts and leatherette should only be treated with a special
solvent-free plastic cleaner . 
Textile covers and trim parts
Textile covers and trim parts (e.g. seats, door trim) should be cleaned regu-
larly with a vacuum cleaner. This will remove surface dirt which could other-
wise be rubbed into the textile material during use. Do not use steam clean-
ers, as the steam could carry the dirt deeper into the textile material. Normal cleaning
We recommend that you use a soft sponge or a commercially available lint-
free, micro-fibre cloth for normal cleaning. Only use brushes on floor cover-
ings and mats, as other textile surfaces could become damaged.
In the case of normal surface dirt you can use a foam cleaner. Use a sponge
to spread the foam on the textile surface and to work it into the material
lightly. However, make sure that the textile material does not become soak-
ing wet. Then dab off the foam with a dry and absorbent cloth (e.g. a micro-
fibre cloth) and vacuum off any residue once the surface is completely dry.
Cleaning stains
Treat drink stains (such as coffee or fruit juice, etc.) with a cleaning solution
for delicate fabrics. The cleaning product solution should be applied with a
sponge. If the stains are difficult to remove, a washing paste can be applied
directly onto the stain and worked into the fabric. The surface will then have
to be wiped with clear water to remove any residue left by the paste. To do
so, use a damp cloth or sponge and then dab the stain with an absorbent
cloth.
Remove chocolate or make-up stains with a cleaning paste (for e.g., soft
soap). Then remove the soap with water (wet sponge).
A spirit-based cleaner can be used to remove grease, oil, lipstick or ball
point pen. Then dab the dissolved grease or colour particles off with an ab-
sorbent cloth or similar. You may also have to treat the stain once more us-
ing washing paste and water.
If the covers or textile trim panels are badly soiled we recommend that you
have them cleaned by a professional cleaning company with a shampoo
and spray.Note
Open Velcro fasteners on clothes can damage the seat upholstery. Make
sure that Velcro fasteners are closed. 

Checking and refilling levels
Note
Diesel vehicles are fitted with a protective device that prevents the insertion
of the wrong fuel hose 1)
. It is only possible to refuel with Diesel nozzles.
● If the pump nozzle is worn, damaged, or if it is very small, it is possible
that it will not be able to open the protective device. Before trying to insert
the pump nozzle by turning it, try a different pump or request specialist
help.
● If you fill the tank from a reserve fuel canister, the protective device will
not open. One way to resolve this is to pour the fuel in very slowly. 

Working on components in the engine compartment
Extra caution is necessary when working on components in
the engine compartment. Always be aware of the danger of injury and scalding as well as the risk of
accident or even fire when working in the engine compartment (e.g. when
checking and refilling fluids). Always observe the warnings listed below
and follow all general safety precautions. The engine compartment of the
vehicle is a potentially hazardous area ⇒ 
.
WARNING
● Switch the ignition off.
● Remove the ignition key.
WARNING (Continued)
● 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 compartment.
● Never spill liquids used for vehicle operation on the engine compart-
ment, as these may catch fire (e.g. the antifreeze in coolant).
● Take care not to cause short circuits in the electrical system, especial-
ly 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 automatically,
and therefore there is a risk of injury.
● Do not unscrew the cap on the coolant expansion tank when the en-
gine 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 compartment while the engine
is running, the rotating components (for example, poly-V belt, alternator,
radiator fan) and the high voltage ignition system are an additional haz-
ard.
● 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 extinguisher immediately available. 

Important safety warnings for handling a vehicle battery
All work on batteries requires specialist knowledge. Please refer to a SEAT
Official Service or a workshop specialising in batteries: risk of burns or ex-
ploding battery!
The battery must not be opened. Never try to change the fluid level of the
battery. Explosive gas is released from the battery that could cause an ex-
plosion.
Wear eye protection.
Battery acid is very corrosive and caustic. Wear protective gloves
and eye protection. In the event of electrolyte splashes, rinse off
with plenty of water.
Fires, sparks, open flames and smoking are prohibited.
The battery should only be charged in a well-ventilated zone. Risk
of explosion!
Keep children away from acid and batteries!
WARNING
● When repairing or working on the electrical system, proceed as fol-
lows:
● 1. Remove the key from the ignition. The negative cable on the bat-
tery must be disconnected.
● 2. When the repair is finished, reconnect the negative pole of the bat-
tery.
● Switch off all electrical consumers before reconnecting the battery.
