Operation
Deceleration until the vehicle has stopped
(only vehicles with automatic gearbox)
If the vehicle in front slows down and stops,
the ACC will also slow down and halt the ve-
hicle. After approximately 3 seconds the sys-
tem will inform the driver that he or she
should take control of the vehicle by means
of an audible and visual warning on the in-
strument panel.
Starting driving after a stopping phase (only
vehicles with automatic gearbox)
After a stopping phase the ACC may begin
driving automatically when the vehicle in
front drives off.
Overtaking
When the turn signal lights up before the ve-
hicle begins an overtaking manoeuvre, the
ACC accelerates the vehicle automatically
and thus reduces the distance from the vehi-
cle in front.
When the vehicle enters the overtaking lane,
if the ACC does not detect another vehicle in
front, it accelerates until it reaches the pro-
grammed speed and maintains it.
System acceleration can be interrupted at
any time by pressing the brake or moving the
third lever backwards ›››
page 154. Driving through a bend
On entering or exiting bends, the radar sen-
sor may no longer determine the vehicle in
front or react to a vehicle in the adjacent lane
››› Fig. 156
A. In these situations the vehicle
may brake unnecessarily or fail to react to re-
act to the vehicle in front. In this case, the
driver has to intervene by accelerating or in-
terrupting the braking process by applying
the brake or pushing the third lever back-
wards ››› page 154.
Drivin

g in tunnels
When driving through tunnels the radar sen-
sor may be limited. Switch off the ACC in tun-
nels.
Narrow or misaligned vehicles
The radar sensor can only detect narrow or
misaligned vehicles when they are within
range ››› Fig. 156
B. This applies particularly
to narrow vehicles such as motorbikes. In
these cases, you should brake as necessary.
Vehicles with special loads and accessories
Special loads and accessories of other vehi-
cles that jut out over the sides, backwards or
over the top may be out of the ACC's range.
Switch off the ACC when driving behind vehi-
cles with special loads and accessories or
when overtaking them. In these cases, you
should brake as necessary. Other vehicles changing lanes
Vehicles changing lanes a short distance
away from your own can only be detected
when they are within range of the sensors.
Consequently, the ACC will take longer to re-
act
››› Fig. 157 C
. In these cases, you should
brake as necessary.
Stationary vehicles
The ACC does not detect stationary objects
while driving, such as traffic tails or damaged
vehicles.
If a vehicle detected by the ACC turns or
moves over and there is a stationary vehicle
in front of it, the ACC will not react to it
››› Fig. 157 D
. In these cases, you should
brake as necessary.
Vehicles driving in the opposite direction
and vehicles crossing your path
The ACC does not react to vehicles approach-
ing from the opposite direction or vehicles
crossing your path.
Metal objects
Metal objects, e.g. rails on the road or sheets
used in road works, can confuse the radar
sensor and cause the ACC to react wrongly.

Driver assistance systems
Switching off the Lane Assist system
in the following situations Due to the limits of the Lane Assist system,
switch it off in the following situations:
● When more attention is required of the
driver
● When driving in a sporty style
● In unfavourable weather conditions
● On roads in poor condition
● In areas of road works Note
The Lane Assist system deactivates when
driving below 60 km/h (40 mph). SEAT driving modes (SEAT Drive
Profile)*
Introduction SEAT Drive Profile enables the driver to
choose between four profiles or modes,
Nor-
mal , Sport
, Eco
and Individual
, that modify the
behaviour of various vehicle functions, pro-
viding different driving experiences. In the FR and X-PERIENCE models equipped
with dynamic chassis control and Navi Sys-
tem Plus, the
Comfort profile is also availa-
b l
e.
In the Leon Cupra model the four profiles are Comfort, Sport, Cupra and Individual.
The Individual profile can be configured ac-
cor

ding to personal preferences. The other
profiles are fixed.
Description Depending on the equipment fitted in the ve-
hicle, SEAT Drive Profile can operate on the
following functions:
Engine
Depending on the profile selected, the en-
gine responds more spontaneously or more
in harmony with the movements of the accel-
erator. Additionally, when
Eco
mode is selec-
ted, the Start-stop function is automatically
activated.
In vehicles with automatic transmission, the
gear change points are modified to position
them in lower or higher engine speed ranges.
Additionally, the Eco1)
mode activates the In- ertia function, enabling consumption to be
further reduced.
In manual gearbox vehicles,
Eco1)
mode cau-
ses the gear change recommendation indica-
tions that appear on the instrument panel to
vary, facilitating more efficient driving.
Dynamic chassis control (DCC)
DCC continuously adapts the shock absorb-
ers to the condition of the road and current
driving conditions, according to the pre-set
programme.
In the event of a fault in the DCC, the follow-
ing message is displayed on the instrument
screen Fault: damping setting.
Address
Power steering becomes more robust in Sport
mode to enable a sportier driving style. In the
Leon Cupra the power steering becomes
more robust in Cupra mode.
Air conditioning
In vehicles with Climatronic, this can operate
in eco 1)
mode, especially restricting fuel con-
sumption. »1)
In the Leon Cupra model, Eco mode is selected
through the Individual profile.

least 30 seconds before starting the engine.
When you then start the engine it may take
longer than normal (up to one minute) to
start firing. This is because air needs to be
bled from the fuel system while starting.
For the sake of the environment
Do not overfill the fuel tank, it may cause the
fuel to overflow if it becomes warm. Note
Diesel vehicles are fitted with a protective de-
vice 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 canis-
ter, the protective device will not open. One
way to resolve this is to pour the fuel in very
slowly. Refuelling with natural gas
Fig. 173
Tank flap open: gas filler mouth 1 ,
filler mouth retainer 2 Before refuelling, the engine and the igni-
tion, mobile telephone and heating must be
switched off separately
››› .
Read the instructions on how to use the natu-
ral gas pump carefully.
The vehicle is not prepared for refuelling with
liquefied natural gas (LNG) ››› . Before refu-
elling with natural gas, make sure you add
the appropriate type of fuel ››› page 195.
Opening the fuel tank cap
The natural gas filler mouth is behind the fuel
tank cap, next to the petrol filler mouth. ●
Unlock the vehicle with the key or with the
central locking button  situated on the driv-
er door ››› page 82 .
● Pr e
ss on the rear area of the flap and open
it.
Refuelling
Things to note: if the ambient temperature is
very high, the natural gas pump protection
against overheating disconnects this auto-
matically.
● Remove the plug from the gas filler mouth
››› Fig. 173 1 .
● Connect the pump filling nozzle to the gas
filler mouth.
● The fuel tank will be full when the pump
c ompr

essor automatically cuts the supply.
● If you wish to finish refuelling in advance,
press the button on the pump to stop the
flow.
Closing the fuel tank cap
● Check that the gas filler mouth retainer 2 is not trapped with the filler nozzle. If neces-
sary, place it in the filler mouth again.
●
Insert the plug in the filler mouth.
● Close the tank flap. Make sure you hear it
click into place. 1)

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.
– Make sure that the bonnet catches onto its
clasp. Do not press down too hard › › › .
WARNING
● For safety reasons the bonnet must always
be completely closed when the vehicle is
moving. Therefore, after closing the bonnet,
always check that the locking element is
properly engaged. This is the case if the bon-
net is flush with the adjacent body panels.
● Should you notice that the bonnet is not
safely secured when the vehicle is moving,
stop the vehicle immediately and close the
bonnet. Failure to follow this instruction
could result in an accident. 199

Engine oil additives
No type of additive should be mixed with the
engine oil. The deterioration caused by these
additives is not covered by the warranty. Note
Before a long trip, we recommend finding an
engine oil that conforms to the correspond-
ing VW specifications and recommend keep-
ing it in the vehicle. This way, the correct en-
gine oil will always be available for a top-up if
needed. Checking engine oil level
Fig. 175
Engine oil dipstick. Read the additional information carefully
›››  page 31
The engine oil dipstick indicates the level of
the oil.
Checking oil level
– Park the vehicle in a horizontal position.
– Briefly run the engine at idle speed until
the operating temperature is reached and
then stop.
– Wait for about two minutes.
– Pull out the dipstick. Wipe the dipstick with
a clean cloth and insert it again, pushing it
in as far as it will go.
– Then pull it out once more and check the oil
level ››› Fig. 175 . Top up with engine oil if
nec e

ssary. Depending on how you drive and the condi-
tions in which the vehicle is used, oil con-
sumption can be up to 0.5 l/1000 km. Oil
consumption is likely to be higher for the first
5,000 km. For this reason the engine oil level
must be checked at regular intervals, prefera-
bly when filling the tank and before a jour-
ney.
WARNING
Any work carried out in the engine compart-
ment or on the engine must be carried out
cautiously.
● When working in the engine compartment,
always observe the safety warnings
››› page 198. 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 Technical Service. 201

could damage the engine
. If there is no
c
oolant in the expansion tank, do not con-
tinue driving. You should obtain professio-
nal assistance ››› .
– If there is still some coolant in the expan-
sion tank, top up to the upper mark.
– Top up with coolant until the level becomes
stable.
– Screw the cap back on correctly.
Any loss of coolant fluid normally indicates a
leak in the cooling system. Take the vehicle
straight to a specialised workshop to have
the cooling system examined. If there are no
leaks in the engine cooling system, a loss of
coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating. WARNING
● The cooling system is under pressure. Do
not unscrew the cap on the coolant expan-
sion tank when the engine is hot: risk of
burns!
● The antifreeze and coolant fluid can be a
health hazard. Therefore, the antifreeze
should be stored in the original container in a
safe place out of reach of children. Failure to
comply could result in poisoning.
● 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.
CAUTION
Do not top up the expansion tank with cool-
ant fluid if it is empty! Air could enter the
cooling system. In this case, stop driving.
Seek specialist assistance. Otherwise, there
is a risk of engine damage. Brake fluid
Topping up the brake fluid Read the additional information carefully
›››  page 32
Checking the brake fluid level
The brake fluid level must be between the
MIN and MAX markings.
However, if the brake fluid level goes down
noticeably in a short time, or drops below the
MIN mark, there may be a leak in the brake
system. Seek specialist assistance. A warn-
ing light on the instrument panel display
monitors the brake fluid level ››› page 71.
In right-hand drive vehicles the brake fluid
reservoir is on the other side of the engine
compartment. Changing brake fluid
The regular intervals at which the brake fluid
should be replaced are listed in the Mainte-
nance Programme. We recommend you have
it replaced at a SEAT Official Service, during
an Inspection Service.
WARNING
● Brake fluid should be stored in the closed
original container in a safe place out of reach
of children. Risk of poisoning!
● If the brake fluid is left in the system for
too long and the brakes are subjected to
heavy use, vapour bubbles may form in the
brake system. This would seriously affect the
efficiency of the brakes and the safety of the
vehicle. This may cause an accident. CAUTION
Brake fluid should not come into contact with
the vehicle paintwork, as it is abrasive. Windscreen washer reservoir

– Replace the battery cover correctly.
– Close the bonnet ››› page 199.
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

control of the vehicle and a serious or fatal
accident.
●
If the warning lamp  lights up, stop im-
mediately and check the tyres.
● If the tyres are inflated at different pres-
sures or if a tyre pressure is too low, this will
increase tyre wear, negatively affecting vehi-
cle stability and increasing braking distan-
ces.
● If tyres are inflated at different pressures or
a tyre pressure is too low, a tyre may be dam-
aged and burst resulting in a loss of control
of the vehicle.
● The driver is responsible for ensuring that
all of the vehicle tyres are correctly inflated
to the right pressure. The recommended tyre
pressure is indicated on the label
››› page 243.
● The ty r
e monitoring system can only oper-
ate correctly if all of the tyres are inflated to
the correct pressure when cold.
● Driving with tyres at the wrong pressure
can damage them and result in an accident.
Ensure that the tyre pressures of all the tyres
correspond to the vehicle load.
● Before starting a journey, always inflate
tyres to the correct pressure.
● Tyres with insufficient pressure are subjec-
ted to more flexing. Due to this, the tyre
could become excessively hot, causing tread
separation and also tyre blow-out.
● With an overloaded vehicle at high speed,
the tyres can overheat and burst resulting in
a loss of vehicle control. ●
Tyre pressures which are too high or too
low reduce the useful life of the tyre, affect-
ing vehicle performance.
● If a tyre has not been punctured and it does
not have to be changed immediately, drive to
the nearest specialised workshop at a moder-
ate speed and have the tyre checked and in-
flated to the correct pressure. WARNING
Observe the safety warnings ››› in Control
and warning lamps on page 71. Note
● If excessively low tyre pressure is detected
with the ignition on, an audible warning will
sound. In the event that there is a fault in the
system, an audible warning will sound.
● Driving on dirt tracks for a long period of
time or driving in a sporty style can tempora-
rily deactivate the TPMS. The control lamp
shows a fault, but disappears when road con-
ditions or the driving style change. Tyre monitoring indicator

TMS (Tyre Mobility System)* Read the additional information carefully
›››  page 33
The Anti-puncture kit* (Tyre Mobility System)
will reliably seal punctures caused by the
penetration of a foreign body of up to about
4 mm in diameter. Do not remove foreign ob-
j
ects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre,
you must again check the tyre pressure about
10 minutes after starting the engine.
You should only use the tire mobility set if
the vehicle is parked in a safe place, you are
familiar with the procedure and you have the
necessary tire mobility set! Otherwise, you
should seek professional assistance.
The tyre sealant must not be used in the
following cases:
● If the wheel rim has been damaged.
● In outside temperatures below -20°C (-4°F).
● In the event of cuts or perforations in the
tyre greater than 4 mm.
● If you have been driving with very low pres-
sure or a completely flat tyre.
● If the sealant bottle has passed its use by
date. WARNING
Using the tyre mobility system can be dan-
gerous, especially when filling the tyre at the
roadside. Please observe the following rules
to minimise the risk of injury:
● Stop the vehicle safely as soon as possible.
Park it at a safe distance from surrounding
traffic to fill the tyre.
● Ensure the ground on which you park is flat
and solid.
● All passengers and particularly children
must keep a safe distance from the work area.
● Turn on the hazard warning lights to warn
other road users.
● Use the tyre mobility system only if you are
familiar with the necessary procedures. Oth-
erwise, you should seek professional assis-
tance.
● The tyre mobility set is intended for tempo-
rary emergency use only until you can reach
the nearest specialised workshop.
● Replace the repaired tyre with the tire mo-
bility set as soon as possible.
● The sealant is a health hazard and must be
cleaned immediately if it comes into contact
with the skin.
● Always keep the tire mobility set out of the
reach of small children.
● Never use an equivalent jack, even if it has
been approved for your vehicle.
● Always stop the engine, apply the hand-
brake lever firmly and engage gear if using a manual gearbox, in order to reduce the risk of
vehicle involuntary movement.
WARNING
A tyre filled with sealant does not have the
same performance properties as a conven-
tional tyre.
● Never drive faster than 80 km/h (50 mph).
● Avoid heavy acceleration, hard braking and
fast cornering.
● Drive for only 10 minutes at a maximum
speed of 80 km/h (50 mph) and then check
the tyre. For the sake of the environment
Dispose of used or expired sealant observing
any legal requirements. Note
A new bottle of sealant can be purchased at
SEAT dealerships. Note
