Air conditioning
● The air conditioner compressor has been
temporarily switched off because the engine
coolant temperature is too high.
● Another fault in the vehicle. Have the air
conditioner checked by a specialised work-
shop. Special Characteristics
If the humidity and temperature outside the
vehicle are high,
condensation
can drip off
the ev
aporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak! Note
After starting the engine, any residual humid-
ity in the air conditioner could mist over the
windscreen. Switch on the defrost function as
soon as possible to clear the windscreen of
condensation. Air vents

On the dash panel: air vents Air vents
To ensure proper heating, cooling and venti-
lation in the vehicle interior, air vents
››› Fig. 140 1 should remain open.
● Turn the corresponding thumbwheel (de-
tail) in the required direction to open and
close the air vents. When the thumbwheel is in the

position, the corresponding air vent
i

s closed.
● Change the air direction using the ventila-
tion grille lever.
There are other additional, non-adjustable air
vents in the dash panel 2 , in the footwell
and in the rear area of the interior. Note
Food, medicine and other heat or cold sensi-
tive objects should never be placed in front of
the air outlets as they may be damaged or
made unsuitable for use by the air coming
from the air vents. 127

Note
● If the selector lever lock does not engage,
there is a fault. The transmission is interrup-
ted 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 posi-
tion 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 system mal-
function. Seek specialist assistance and
have the system checked. Changing gears in tiptronic mode*

Operation
– Take your left foot off the brake pedal. WARNING
● Always adapt your driving style to the traf-
fic conditions.
● Only use the launch control programme
when road and traffic conditions permit, and
make sure your manner of driving and accel-
erating the vehicle does not inconvenience or
endanger other road users.
● Make sure that the ESC remains switched
on. Please note that when the ASR and ESC
are deactivated, the wheels may start to spin,
causing the vehicle to lose grip. Risk of acci-
dent!
● After putting the vehicle into gear, the
“sport” mode of the ESC should be deactiva-
ted again by briefly pressing the OFF but-
ton. Note
● After using the Launch control programme,
the temperature in the gearbox may have in-
creased considerably. In this case, the pro-
gramme could be disabled for several mi-
nutes. The programme can be used again af-
ter the cooling phase.
● Accelerating with the Launch control pro-
gramme places a heavy load on all parts of
the vehicle. This can result in increased wear
and tear. Downhill speed control*
The downhill speed control function helps
the driver when driving down steep gradi-
ents.
Downhill speed control is activated when the
selector lever is in D/S and the driver applies
the foot brake. The automatic gearbox auto-
matically engages a lower gear that is suita-
ble for the slope. The downhill speed control
function attempts to maintain the speed at
which the vehicle was travelling when the
foot brake was applied (subject to the laws of
physics and technical drive limitations). It
may be necessary to adjust the speed again
using the foot brake in certain situations. Giv-
en that the downhill speed control can only
change down to 3rd gear, on very steep de-
scents the tiptronic mode may be required. In
this case, manually reduce the tiptronic to
2nd or 1st gear to use the engine brake and
reduce the charge on the brakes.
Downhill speed control is deactivated as
soon as the road levels out again or you
press the accelerator pedal.
On vehicles with cruise control system*
››› page 150 , downhill speed control is acti-
v at
ed when you set a cruising speed. WARNING
The downhill speed control cannot defy the
laws of physics. Therefore, speed cannot be maintained constant in all situations. Always
be prepared to use the brakes!
Inertia mode
The inertia mode enables the kinetic energy
of the vehicle to be harnessed enabling cer-
tain stretches to be driven without using the
accelerator. This enables fuel to be saved.
Use the inertia mode to “let the vehicle roll”
before, for example, arriving in a town.
Switching on inertia mode
Important: selector lever must be in position
D, gradients below 12 %.
–
Select, in SEAT Drive Profile*, Eco mode
››› page 169 .
– Tak

e your foot off the accelerator.
The driver message Inertia will be displayed.
At speeds higher than 20 km/h (12 mph), the
gearbox will automatically disengage and the
vehicle will roll freely, without the effect of
the engine brake. While the vehicle rolls, the
engine runs at idling speed.
Stopping inertia mode
– Press the brake or the accelerator pedal.
To make use of the braking force and switch
off the engine again, simply press the brake
pedal briefly.

Operation
 Gearbox: press the brake and engage a
gear again.
If the fault was caused by a gearbox with a
high temperature, this driver message will be
displayed when the gearbox has cooled
again.
Run-in and economical driving Running in the engine A new vehicle should be run in over a dis-
tance of 1500 km (1000 miles). For the first
1,000 km the engine speed should not ex-
ceed 2/3 of the maximum permissible engine
speed. In doing so, do not accelerate at full
throttle and do not drive with a trailer! From
1000 to 1500 km (600 to 1000 miles) you
can gradually increase the engine rpm and
road speed.
During its first few hours of running, the in-
ternal friction in the engine is greater than
later on when all the moving parts have bed-
ded down.
How the vehicle is driven for the first 1,500
km influences the future engine perform-
ance. Subsequently, also drive at a moderate
rate, especially when the engine is still cold:
this will lead to less engine wear and tear
and will prolong its useful life. You should also avoid driving with the engine
speed too
low
. Change down to a lower gear
when the en
gine no longer runs “smoothly”.
If the engine revs too much, cut fuel injection
to protect the engine.
Environmental friendliness Environmental protection is a top priority in
the design, choice of materials and manufac-
ture of your new SEAT.
Constructive measures to encourage
recycling
● Joints and connections designed for easy
dismantling
● Modular construction to facilitate disman-
tling
● Increased use of single-grade materials.
● Plastic parts and elastomers are marked in
accordance with ISO 1043, ISO 11469 and
ISO 1629.
Choice of materials
● Use of recycled materials.
● Use of compatible plastics in the same part
if its components are not easily separated.
● Use of recycled materials and/or materials
originating from renewable sources. ●
Reduction of volatile components, includ-
ing odour, in plastic materials.
● Use of CFC-free coolants.
Ban on heavy metals, with the exceptions
dictated by law (Annex II of ELV Directive
2000/53/EC): cadmium, lead, mercury, hexa-
v al

ent chromium.
Manufacturing methods
● Reduction of the quantity of thinner in the
protective wax for cavities.
● Use of plastic film as protection during ve-
hicle transport.
● Use of solvent-free adhesives.
● Use of CFC-free coolants in cooling sys-
tems.
● Recycling and energy recovery from resi-
dues (RDF).
● Improvement in the quality of waste water.
● Use of systems for the recovery of residual
heat (thermal recovery, enthalpy wheels,
etc.).
● The use of water-soluble paints.

Driver assistance systems
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake flu-
id level is monitored electronically.
Brake servo
The brake servo increases the pressure you
apply to the brake pedal. It works only when
the engine is running. WARNING
● Apply the brakes heavily to clean the brake
system only in a suitable traffic situation. Do
not put other road users in danger: there is
risk of causing an accident.
● Ensure the vehicle does not move while in
neutral, when the engine is stopped. Failure
to follow this instruction could result in an
accident.
● If the brake fluid loses its viscosity and is
subjected to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes. CAUTION
● Never let the brakes “drag” by leaving your
foot on the pedal when it is not necessary to
brake. This overheats the brakes, resulting in
longer stopping distances and greater wear.
● Before driving down a long, steep gradient,
it is advisable to reduce speed and select a
lower gear. This makes use of engine braking and relieves the brakes. If you still have to
use the brakes, it is better to brake firmly at
intervals than to apply the brakes continu-
ously.
Note
● If the brake servo is out of action, for exam-
ple when the car is being towed, you will
have to press the brake pedal considerably
harder than normal to make up for the lack of
servo assistance.
● If you wish to equip the vehicle with acces-
sories such as a front spoiler or wheel covers,
it is important that the flow of air to the front
wheels is not obstructed, otherwise the
brakes can overheat. Hill driving assistant*
This function is only included in vehicles with
ESC.
The hill driving assistant helps the driver to
move off and upward on a hill when the vehi-
cle is stationary.
The system maintains brake pressure for ap-
proximately two seconds after the driver
takes his foot off the brake pedal to prevent
the vehicle from lurching backward when it is
started. During these 2 seconds, the driver
has enough time to release the clutch pedal
and accelerate without the vehicle moving
and without having to use the handbrake,making start-up easier, more comfortable
and safer.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● doors closed,
● vehicle completely stationary,
● engine running and foot on the brake,
● besides having a gear engaged or being in
neutral for manual gear change and with the
selector lever at position S,
D or R for an au-
tomatic gearbox.
This system is also active when reversing up-
hill. WARNING
● 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
conditions. Depress the brake pedal or use
the hand brake immediately.
● If the engine stalls, depress the brake ped-
al or use the hand brake immediately.
● When following a line of traffic uphill, if you
want to prevent the vehicle from rolling back
accidentally when starting off, hold the brake
pedal down for a few seconds before starting
off. » 147

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.

Operation
WARNING
The intelligent technology in the ACC cannot
overcome the system's inherent limitations
or change the laws of physics. If used negli-
gently or involuntarily, it may cause serious
accidents and injuries. The system is not a re-
placement for driver awareness.
● Adapt your speed and safe distance to the
vehicle in front of you at all times to suit visi-
bility, weather, road and traffic conditions.
● Do not use the ACC when visibility is bad,
on steep roads, with several bends or in slip-
pery circumstances such as snow, ice, rain or
loose gravel, or on flooded roads.
● Never use the ACC when driving off-road or
on unpaved roads. The ACC has been de-
signed for use on paved roads only.
● The ACC does not react on approaching a
fixed obstacle, such as the tail of a traffic
jam, a damaged vehicle or a vehicle stopped
at the traffic lights.
● The ACC does not react to people or animal
or vehicles crossing your path or which ap-
proach you head-on in the same lane.
● If the ACC does not reduce speed sufficient-
ly, brake the vehicle immediately by applying
the pedal.
● If you are driving using the spare wheel,
the ACC system could automatically switch
off during the journey. Switch off the system
when starting off. ●
If the vehicle continues to move involuntar-
ily after a driver intervention prompt, brake
the vehicle by applying the pedal.
● If the dash panel displays a driver interven-
tion prompt, adjust the distance yourself.
● The driv er shou
ld be ready to accelerate or
brake by him/herself at all times. CAUTION
If you have the sensation that the radar sen-
sor is damaged, disconnect the ACC. This will
avoid possible damage. If this occurs have it
adjusted. ● Repairs to the radar sensor require special-
ist knowledge and special tools. SEAT recom-
mends visiting a SEAT dealership for this pur-
pose. Note
● If the ACC system does not work as descri-
bed in this chapter, do not use it until it has
been checked by a specialised workshop.
SEAT recommends visiting a SEAT dealership
for this purpose.
● Maximum speed with the ACC activated is
limited to 160 km/h (100 mph).
● When the ACC is switched on, strange
noises may be heard during automatic brak-
ing cause by the braking system. Messages on display, control and
warning lamps

Operation
Automatic braking
If the driver also fails to react to the pre-warn-
ing, the system may brake the vehicle auto-
matically, by progressively increasing braking
effect driving at a speed of between approxi-
mately 5 km/h (3 mph) and 210 km/h
(130 mph). By reducing speed in case of a
possible collision, the system may contribute
to reducing the consequences of an accident.
Front assist
If the Front Assist notices that the driver is
not braking sufficiently in case of a collision
hazard, the system can increase braking ef-
fect and thus avert the collision when driving
at a speed of between approximately 5 km/h
(3 mph) and 210 km/h (130 mph). Front as-
sist only acts while the brake pedal is press-
ed down hard. WARNING
The intelligent technology in the Front Assist
cannot change the laws of physics. The driver
is always responsible for braking in time. If
the Front Assist issues a warning, then, de-
pending on the traffic circumstances, you
must brake immediately or dodge the obsta-
cle.
● Adapt your speed and safe distance to the
vehicle in front of you at all times to suit visi-
bility, weather, road and traffic conditions.
● The Front Assist alone cannot avoid acci-
dents and serious injuries. ●
In complex driving situations, the Front As-
sist may issue unnecessary warnings and in-
tervene unnecessarily in braking, such as in
traffic islands.
● If the operation of the Front Assist is im-
paired, for example, by dirt or because the ra-
dar sensor has lost its settings, the system
may issue unnecessary warnings and inter-
vene inopportunely in the braking.
● During driving, the Front Assist does not re-
act to people or animals or vehicles crossing
your path or which approach you head-on in
the same lane.
● The driver must always be ready to take
over the control of the vehicle. Note
● When the Front Assist causes a braking,
the brake pedal is “harder”.
● Automatic interventions by the Front Assist
on the brakes may be interrupted by pressing
the clutch, accelerator or moving the wheel.
● If the Front Assist does not work as descri-
bed in this chapter (e.g. in intervenes several
times unnecessarily), switch it off. Have the
system checked by a specialised workshop.
