Operation
If the engine does not start immediately,
sw it
c
h the starter off after 10 seconds and try
again after half a minute. If the engine still
does not start, the fuel pump fuse should be
checked ››› page 104, Fuses. WARNING
● Never s t

art or run the engine in unventila-
ted or closed rooms. The exhaust gases con-
tain carbon monoxide, an odourless and col-
ourless poisonous gas. Risk of fatal acci-
dents. Carbon monoxide can cause loss of
consciousness and result in death.
● Never leave the vehicle unattended if the
engine is
running.
● Never use “cold start sprays”, they could
explode or c
ause the engine to run at high
revs. Risk of injury. CAUTION
● When the engine i s

cold, you should avoid
high engine speeds, driving at full throttle
and over-loading the engine. Risk of engine
damage.
● The vehicle should not be pushed or towed
more than 50 metr
es to start the engine. Un-
burnt fuel could enter the catalytic converter
and damage it.
● Before attempting to push-start or tow a ve-
hicle in or
der to start it, you should first try to
start it using the battery of another vehicle.
Please observe and follow the notes on the
›››  page 71, How to jump start. For the sake of the environment
Do not warm-up the engine by running the
engine w ith the

vehicle stationary. Start off
immediately, driving gently. This helps the
engine reach operating temperature faster
and reduces emissions. Starting diesel engines
The engine can only be started using a genu-
ine S
EA

T key with its correct code.
– Move the gearbox lever to the neutral posi-
tion and depre s

s the clutch pedal thor-
oughly and hold it in this position for the
starter to turn the engine on.

Glow plug system for diesel engines
To avoid unnecessary discharging of the bat-
tery, do not use any other major electrical
equipment while the glow plugs are pre-heat-
ing.
Start the engine as soon as the glow plug
warning lamp goes out.
Starting a diesel engine after the fuel tank
has run dry
If the fuel tank has been completely run dry,
it may take longer than normal (up to one mi-
nute) to start a diesel engine after refuelling.
This is because the fuel system must elimi-
nate air first. WARNING
Observe the safety warnings ›››
in Starting
petro l
engines on page 174. CAUTION
● When the engine i s

cold, you should avoid
high engine speeds, driving at full throttle
and over-loading the engine. Risk of engine
damage.
● The vehicle should not be pushed or towed
more than 50 metr

side light goes out. WARNING
Any accidental movement of the vehicle could
re s

ult in serious injury.
● When switching on the ignition, do not
pre
ss the brake or clutch pedal, otherwise
the engine could start immediately. WARNING
If vehicle keys are used negligently or with-
out due c ar

e, this may cause accidents and
serious injury.
● Never leave any key inside the vehicle
when exitin
g. Otherwise, a child or unauthor-
ised person could lock the vehicle, start the
engine or connect the ignition and, in this
way, operate electronic equipment (e.g. the
windows). Note
● Bef or

WARNING
You should switch on the ESC Sport mode on-
ly if the tr

affic conditions and your driving
ability allow you to do so safely: risk of skid-
ding!
● With ESC in Sport mode, the stabilising
function w
ill be limited to allow for a sportier
drive. The driving wheels could spin and the
vehicle could skid. Note
If the ASR is disconnected or the ESC’s Sport
mode is sel

ected, cruise control* will be
switched off. Electronic differential lock (EDS)*
The EDL operates along with the ABS in vehi-
c
l
e

s equipped with Electronic Stability Con-
trol (ESC)*.
EDL helps the vehicle to start moving, accel-
erate and climb a gradient in slippery condi-
tions where this may otherwise be difficult or
even impossible.
It uses the ABS sensors to monitor the speed
of the driven wheels.
At speeds of up to approximately 80 km/h
(50 mph), it is able to balance out differences in the speed of the driven wheels of approxi-
mately

100 rpm/min caused by a partially
slippery road surface. It does this by braking
the wheel which has lost traction and distrib-
uting more driving force to the other driven
wheel via the differential.
To prevent the disc brake of the braking
wheel from overheating, the EDL cuts out au-
tomatically if subjected to excessive loads.
The vehicle will continue to function normally
without EDL. For this reason, the driver is not
informed that the EDL has been switched off.
The EDL will switch on again automatically
when the brake has cooled down.
Control lamp
A malfunction in the EDL is indicated by the
ESC control lamp . Take the vehicle to a
specialised workshop as soon as possible. WARNING
● When acc el

erating on a slippery surface,
for example on ice and snow, press the accel-
erator carefully. Despite EDL, the driven
wheels may start to spin. This could impair
the vehicle's stability.
● Always adapt your driving style to suit road
conditions
and the traffic situation. Do not let
the extra safety afforded by EDL tempt you in-
to taking any risks when driving, this can
cause accidents. CAUTION
Modifications to the vehicle (e.g. to the en-
gine, the brak e sy

stem, running gear or any
components affecting the wheels and tyres)
could affect the efficiency of the EDL
››› page 259. Hydraulic Brake Assist (HBA)*
The function (Hydraulic Brake Assist HBA) is
only
inc

luded in vehicles with ESC.
In an emergency, most drivers brake in time,
but not with maximum force. This results in
unnecessarily long braking distances.
This is when the brake assist system comes
into action. When pressing the brake pedal
rapidly, the assistant interprets it as an emer-
gency. It very quickly builds up the full brake
pressure so that the ABS can be activated
more quickly and efficiently, thus reducing
braking distance.
Do not reduce the pressure on the brake ped-
al, since the brake assist system switches off
automatically as soon as you release the
brake.
Automatic hazard warning lights activation
The brake lights flash automatically to indi-
cate that the vehicle is braking suddenly or in

Operation
WARNING
Observe the safety warnings ››› in Selector
lev er po
sitions on page 189.
● Never allow the brake to rub and do not use
the brake ped
al too often or for long periods.
Constant braking causes overheating in the
brakes. This could significantly reduce brak-
ing power, increase braking distance or even
result in the total failure of the brake system.
● To avoid rolling back on gradients always
hold the
vehicle with the footbrake or hand-
brake if you have to stop. CAUTION
● If y

ou stop the vehicle on a gradient, do not
attempt to stop it from rolling by depressing
the accelerator when a gear has been selec-
ted. This could cause overheating and dam-
age the automatic gearbox. Apply the hand-
brake firmly or press the brake pedal in order
to prevent the vehicle from rolling back.
● If you allow the car to roll with the selector
lever in po
sition N with the engine switched
off, the automatic gearbox will be damaged
as it will not be lubricated.
● In certain driving situations or traffic condi-
tions, suc
h as frequently starting, prolonged
“creeping” of the vehicle or traffic jams with
continuous stoppages, the gearbox could overheat causing damage! If the warning
lamp


lights up, stop the vehicle as soon as
possible and wait for the gearbox to cool
››› page 194. Kick-down feature
The kick-down feature allows maximum ac-
cel
er

ation to be reached.
When the accelerator pedal is pressed right
down past the point of resistance at full throt-
tle, the gearbox will shift down to a lower
gear, depending on road speed and engine
speed. The upshift to the next higher gear is
delayed until the engine reaches maximum
rpm. WARNING
Please note that if the road surface is slip-
pery or w

et, the kick-down feature could
cause the driving wheels to spin, which could
result in skidding. Launch control program

Operation
The driver message Inertia wi
l l be dis-
played. At speeds higher than 20 km/h (12
mph), the gearbox will automatically disen-
gage and the vehicle will roll freely, without
the effect of the engine brake. While the vehi-
cle rolls, the engine runs at idling speed.
Stopping inertia mode
– Press the brake or the accelerator pedal.
To mak
e use of the braking force and switch
off the engine again, simply press the brake
pedal briefly.
Applying both the inertia mode (= prolonged
section with less energy) and the switching
off using inertia (= shorter section without
the need for fuel) facilitates improved fuel
consumption and emission balance. WARNING
● If the iner ti

a mode has been switched on,
take into account, when approaching an ob-
stacle and releasing the accelerator pedal,
that the vehicle will not decelerate in the usu-
al manner: risk of accident!
● When using inertia mode while travelling
down hil
ls, the vehicle can increase speed:
risk of accident!
● If other users drive your vehicle, warn them
about inerti
a mode. Note
● Inerti a mode i

s only available in eco (SEAT
Drive Profile*) driving mode.
● The driver message Inertia is on
ly dis-
played with the current consumption. In iner-
tia mode the gear will no longer be displayed
(for example “E” will appear instead of “E7”).
● On downhill sections with gradients above
15 %, the inertia mode w
ill automatically be
switched off temporarily. Emergency program
A backup programme is in place if a fault

d oc

cur in the control system.
If all the positions of the selector lever are
shown over a light background on the instru-
ment panel display, there is a system fault
and the automatic gearbox will operate in
with the backup programme. When the back-
up programme is activated, it is possible to
drive the vehicle, however, at low speeds and
within a selected range of gears. In some ca-
ses driving in reverse gear may not be possi-
ble. CAUTION
If the gearbox operates with the backup pro-
gramme, t ak

Introduction WARNING
● Bec au

se of the high temperatures which
can occur in the exhaust purification system
(catalytic converter or diesel particulate fil-
ter), do not park the vehicle where the ex-
haust can come into contact with flammable
materials under the car (e.g. on grass or at
the forest edge). Fire hazard!
● Do not apply wax underneath the vehicle
around the ar
ea of the exhaust system: Fire
hazard! Note
While the control lamps , ,  or  re-
m ain lit, ther

e may be engine problems, fuel
consumption may increase and the engine
may lose power. Catalytic converter
To maintain the useful life of the catalytic
con
v

erter
– Use only unleaded petrol with petrol en-
gines, as

lead damages the catalytic con-
verter.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish
with too muc

h engine oil ››› page 277, Top-
ping up engine oil.
– Never tow the vehicle to start it, use jump
lea

ds if necessary ›››
 page 71.
If you notice misfiring, uneven running or
loss of power when the vehicle is moving, re-
duce speed immediately and have the vehi-
cle inspected at the nearest specialised
workshop. In general, the exhaust warning
lamp will light up when any of the described
symptoms occur ›››
page 121. If this hap-
pens, unburnt fuel can enter the exhaust sys-
tem and escape into the environment. The
catalytic converter can also be damaged by
overheating. CAUTION
Never run the fuel tank completely dry be-
cau se the irr

egularity of the fuel supply may
cause ignition problems. This allows unburnt
fuel to enter the exhaust system, which could
cause overheating and damage the catalytic
converter. For the sake of the environment
Even when the emission control system is
work in

g perfectly, there may be a smell of
sulphur from the exhaust gas under some
conditions. This depends on the sulphur con-
tent of the fuel used. Quite often the problem
can be solved by changing to another brand
of fuel. Diesel particulate filter
3 App
lies to vehicles with diesel engine
The die
sel engine particulate filter eliminates
most of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. The diesel particulate filter is
cleaned automatically without need for indi-
cation by the warning lamp . This may be
noticed because the engine idle speed in-
creases and an odour may be detected.
If automatic filter purification cannot be car-
ried out (because only short trips are taken,
for example), soot will accumulate on the fil-
ter and the Diesel particulate filter warning
lamp will  switch on.
Facilitate the automatic filter cleaning proc-
ess by driving in the following manner: drive
for approximately 15 minutes at a minimum
speed of 60 km/h (37 mph) in 4th or 5th gear
(automatic gearbox: gear S). Maintain the en-
gine speed at approximately 2,000 rpm. The
rise in temperature causes the soot on the
200

Driving
filter to burn. On completion of the cleaning
the w arnin
g l
amp will switch off. If the warn-
ing lamp does not switch off, go immediately
to a specialised workshop to rectify the prob-
lem.
Engine management*  This warning lamp monitors the engine man-
agement
sy

stem for petrol engines.
The warning lamp  (Electronic Power Con-
trol) lights up when the ignition is switched
on while system operation is being verified. It
should go out once the engine is started.
If there is a fault in the electronic engine
management system while you are driving,
this warning lamp will light up. Take the vehi-
cle to a specialised workshop as soon as
possible and have the engine checked.

into c
on

sideration:
● For vehicles fitted with a catalytic converter
ensur
e that unleaded petrol is available for
the journey. See chapter ››› page 269, Fuel.
Automobile organisations will have informa-
tion about service station networks selling
unleaded fuel.
● In some countries, it is possible that your
car model i

s not sold, and therefore some
spare parts are not available or the technical
services may only be able to carry out limited
repairs.
SEAT importers and distributors will gladly
provide information about the technical prep-
aration that your vehicle requires and also
about necessary maintenance and repair
possibilities.

Conditions for the integration of a trailer in
the anti-theft alarm system.
● The vehicle is factory-equipped with an an-

arm system and a towing bracket
device.
● The trailer is connected electrically to the
tow
ing vehicle by the trailer connector.
● The electrical system of the vehicle and the

● The vehicle is locked with the ignition key
and the anti-theft al

ar e. W

eight distribution
The weight di
stribution of a loaded trailer
with an unladen vehicle is very unfavourable.
However, if this cannot be avoided, drive ex-
tra slowly to allow for the unbalanced weight
distribution.
Speed
The stability of the vehicle and trailer is re-
duced with increasing speed. For this reason,
it is advisable not to drive at the maximum
permissible speed in an unfavourable road,
weather or wind conditions. This applies es-
pecially when driving downhill.
You should always reduce speed immediately
if the trailer shows the slightest sign of snak-
ing. Never try to stop the “snaking” by in-
creasing speed.
Always brake in due course. If the trailer has
an overrun brake, apply the brakes gently at
first and then, firmly. This will prevent the
jerking that can be caused by locking of trail-
er wheels. Select a low gear in due course
before going down a steep downhill. This en-
ables you to use the engine braking to slow
down the vehicle.
Reheating
At very high temperatures and during pro-
longed slopes, driving in a low gear and high
engine speed, always monitor the coolant
temperature gauge ››› page 120. Electronic stability control*

Advice
Removing snow – Use a small brush to remove snow from the
windo
w
s and mirrors.
Removing ice – Use a de-icer spray.
Use a cl
ean cloth or chamois leather to dry
the windows. The chamois leathers used on
painted surfaces are not suitable to clean
windows because they are soiled with wax
deposits which could smear the windows.
If possible, use a de-icing spray to remove
ice. If you use an ice scraper, push it in one
direction only without swinging it.
Use window cleaner or a silicone remover to
clean rubber, oil, grease and silicone depos-
its off.
Wax deposits can only be removed with a
special cleaner available at your Technical
Service. Wax deposits on the windscreen
could cause the wiper blades to judder. Add-
ing a window cleaner that dissolves wax to
the windscreen washer fluid reservoir pre-
vents wiper blades from juddering, but the
wax deposits are not removed. CAUTION
● Never u se w

arm or hot water to remove
snow and ice from windows and mirrors. This
could cause the glass to crack! ●
The heatin g el

ement for the rear window is
located on the inner side of the window. To
prevent damage, do not put stickers over the
heating elements on the inside of the win-
dow. Cleaning windscreen wiper blades
Clean wiper blades improve visibility.
1. Use a soft cloth to remove dust and dirt
from the w ind

screen wiper blades.
2. Use window cleaner to clean the wind- scr

een wiper blades. Use a sponge or a
cloth to remove stubborn dirt.
Care of rubber seals If rubber seals are well looked after, they will
not

eez

e so quickly.
1. Use a soft cloth to remove dust and dirt from the rubber seal
s.
2. Apply a specialist care product to the rub- ber seals.
The rubber s

trips on the doors, windows, etc.
will remain pliable and last longer if they are
treated with a suitable rubber care product
from time to time (for example silicone
spray). Caring for rubber seals will also prevent pre-
matur

e ageing and leaks. The doors will be
easier to open. If rubber seals are well looked
after, they will not freeze so quickly in winter.
Door lock cylinder The door lock cylinders can freeze up in win-
ter
.
T

o de-ice the lock cylinders you should only
use spray with lubricating and anti-corrosive
properties.
Cleaning chrome parts 1. Clean chrome parts with a damp cloth.
2. Polish chrome parts with a soft, dry cloth.
If
thi
s

does not provide satisfying results, use
a specialist chrome cleaning product.
Chrome cleaning products will remove stains
from the surface. CAUTION
To prevent scratching chrome surfaces:
● Never use an abrasive cleaning product on
chr ome.
● Do not

clean or polish chrome parts in a
sandy or du
sty environment.264

Checking and refilling levels
We recommend the use of diesel
f uel which
complies to European standard EN 590. If
diesel fuel which meets European standard
EN 590 is not available, the Cetane number
(CZ) must, at minimum, be 51. If the engine
is equipped with a particulate filter, the sul-
phur content of the fuel must be below 50
parts per million.
Winter-grade diesel
Summer fuel becomes thicker in winter and it
is more difficult to start the engine. For this
reason, petrol stations in some countries al-
so offer winter diesel with improved fluidity
when cold (winter-grade diesel). CAUTION
● The v ehic

le is not designed for the use of
FAME fuel (biodiesel). The fuel system would
be damaged if you used biodiesel.
● Do not mix fuel additives, the so-called
“thinners”, petro
l or similar additives with
diesel fuel.
● If poor-quality diesel fuel is used, it may be
neces
sary to drain the fuel filter more fre-
quently than is specified in the Maintenance
Programme. We recommend having this done
by a specialised workshop. If water is allowed
to collect in the filter, this can cause engine
performance problems. AdBlue

Inf orm
ation on AdBlue ® The consumption of AdBlue
®
depends on
y
our personal driving style, the temperature
of the system and on the outdoor tempera-
ture when the vehicle is used.
AdBlue ®
freezes at temperatures of -11°C
(+13°F). The system has heating elements
that guarantee its operation even at low tem-
peratures.
The AdBlue ®
tank level capacity is approxi-
mately 10.4 litres.
The AdBlue ®
tank should never be empty.
When the distance to empty drops below
2400 km, a warning to refill the AdBlue ®
tank
will appear on the dash panel display
››› page 271. If this information is ignored,
later on it will not be possible to re-start the
engine. If this warning does not appear, it is
not necessary to refill the AdBlue ®
tank.
AdBlue ®
