Automatic gearbox malfunction Back-up programme
When autom
atic
gearbox warning and indica-
tion lamps light up on the instrument panel,
there may be a system malfunction
››› page 137. In the event of some faults the
automatic gearbox functions using a backup
programme. When the programme is activa-
ted, it is possible to drive the vehicle, howev-
er, at low speeds and within a selected range
of gears.
With the manual gearbox, in some cases it is
not possible to drive with all the gears .
In all cases the automatic gearbox must be
checked at a specialised workshop.
Automatic gearbox overheating
The automatic gearbox can overheat with a
prolonged start up, or when stopping and
starting continuously. This overheating is dis-
played with a warning lamp  in the instru-
ment panel. Additionally, an audible warning
can be heard. Stop and let the gearbox cool
››› .
The v
ehic

le moves forward or back despite
having selected a gear range
When the vehicle does not move in the re-
quired 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 dir

ection, there is a system malfunc-
tion. Seek specialist assistance and have the
system checked. CAUTION
● When the ge arbo

x is displayed as overheat-
ing for the first time, the vehicle must be
parked safely or must be driven at a speed of
more than 20 km/h (12 mph).
● When the warning lamp lights up and the
audible w
arning is heard, the vehicle must be
parked safely and the engine switched off.
Let the gearbox cool down.
● To prevent damage to the gearbox, driving
must
only be continued when the warning
lamps are no longer lit up. While the gearbox
is overheated, starting up and driving, even
at a slow speed should be avoided. Recommended gear display

How the vehicle is driven for the first 1,500
km influences the future engine perform-
ance. Throughout the life of the vehicle, it
should be driven at a moderate speed, espe-
cially when the engine is cold, as this will re-
duce engine wear and increase its useful life.
Never drive at extremely low engine speeds.
Change down to a lower gear when the en-
gine no longer runs “smoothly”. Up to 1,000
kilometres the following instructions apply:
● Do not use full throttle.
● Do not force the engine above two thirds of
its max
imum speed.
Between 1,000 and 1,500 kilometres, gradu-
ally increase power until reaching the maxi-
mum speed and high engine speeds.

Operation
For the sake of the environment
Even when the emission control system is
work in
g perfectly, there may be a smell of
sulphur under certain conditions. This de-
pends on the sulphur content of the fuel
used. Driving abroad
In some countries, certain safety regulations
and requir
ements

are in force relating to ex-
haust gas emissions, which differ from the
technical characteristics of the vehicle. Be-
fore travelling abroad, SEAT recommends you
consult a technical service about the legal re-
quirements and the following points:
● Does the vehicle need technical modifica-
tions f

or driving abroad, for example, adjust-
ment of the headlamps?
● Does the vehicle have all the tools, diag-
nostic
s equipment and spare parts required
for inspections and repairs?
● Are there any SEAT dealers in the destina-
tion countr
y?
● For petrol vehicles: Is unleaded petrol avail-
able at
the right octane rating?
● For diesel engines: is diesel fuel available
with a low s
ulphur content?
● Are a suitable engine oil ( ›››

page 186) and
other engine fluids complying with SEAT specifications available in the destination
countr

y?
● Will the navigation system fitted at the fac-
tory
operate correctly in the destination coun-
try with the available navigation data?
● Are special tyres required in the destination
countr
y? CAUTION
SEAT does not accept liability for any damage
to the v

ehicle due to the use of a lower quali-
ty fuel, an inadequate service or the non-
availability of genuine spare parts. Driving along flooded roadways
To prevent damage to the vehicle when driv-
in
g thr
ough w

ater, for example, along a floo-
ded road, please observe the following:
● Check the depth of the water before enter-
ing the flooded z
one. The water should never
come above the lower edge of the bodywork
››› .
● Do not drive faster than a pedestrian.
● Do not stop in the water, use reverse gear
or sw it
c

h off the engine.
● Oncoming traffic will cause waves which
raise the l
evel of the water, making it difficult
to cross the water. ●
Disc
onnect the Start-Stop system whenever
crossing water. WARNING
When driving through water, mud, melted
sno w

, etc., please remember that due to
damp or frozen brake discs and shoes in win-
ter, the braking effect may be delayed, there-
fore the required braking distance is greater.
● “Dry the brakes and remove ice” by braking
caref
ully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process.
● After driving through water, avoid sudden
sharp manoeu
vres. CAUTION
● Drivin g thr

ough flooded areas may severely
damage vehicle components such as the en-
gine, transmission, drive train or electrical
system.
● Never drive through salt water as salt cau-
ses c
orrosion. Always rinse any parts of the
vehicle which have been in contact with salt
water. 146

Br ak
in
g and stability systems
Brake assist systems The assisted braking systems ESC*, ABS,
EBV
, B

AS, ASR, TC and EDL only operate when
the ignition is switched on. They contribute
significantly to increasing active safety.
Electronic Stability Control (ESC)*
ESC* reduces the risk of skidding and increa-
ses the vehicle stability by braking individual
wheels under specific driving conditions.
ESC* detects critical handling situations,
such as understeer, oversteer and wheelspin
on the driven wheels. The system stabilises
the vehicle by braking individual wheels or
by reducing the engine torque.
The ESC* has limits. It is important to realise
that ESC* is also subject to the laws of phys-
ics. ESC* will not be able to deal with all sit-
uations with which drivers may be faced. For
example, if the road surface changes sudden-
ly then ESC* will not be useful in all cases. If
the vehicle suddenly enters a section cov-
ered by water, mud or snow then ESC* will
not provide assistance in the same way as on
dry ground. If the vehicle loses its grip on the ground and moves on a film of water (“aqua-
pl
anin

g”), the ESC* will not be able to help
the driver control the vehicle due to the loss
of adherence with the road surface prevent-
ing braking and steering. If the vehicle is
driven through series of bends at high
speed, the ESC* will not always be as effec-
tive: the vehicle reaction to aggressive driv-
ing is not the same as at reduced speeds.
Adjust your speed and driving style to suit
visibility, and weather, road and traffic condi-
tions. ESC* cannot push the limits of the laws
of physics; improve the transmission availa-
ble or maintain the vehicle on the road if a
lack of driver attention creates an inevitable
situation. Otherwise, ESC* assists in main-
taining vehicle control in extreme situations
and uses the movements of the steering
made by the driver to maintain the vehicle
moving in the desired direction. If the vehicle
is driven at such a speed that it will leave the
road before ESC* can intervene then the sys-
tem cannot provide assistance.
The ABS, BAS, ASR and EDL systems are in-
corporated into the ESC*. The ESC* is always
on 1)
.
Anti-lock system (ABS)
ABS can prevent the wheels from locking dur-
ing braking until just before the vehicle stops thus helping the driver to steer the vehicle
and maintain c
ontrol. This means that, even
during full braking, the risk of skidding is re-
duced:
● Press and hold the brake pedal fully. Do not
remov
e your foot from the brake pedal or re-
duce braking force!
● Do not “pump” the brake pedal, or reduce
brakin
g force!
● Maintain vehicle direction when braking
ful
ly.
● When the brake pedal is released or when
the brake f
orce is reduced, ABS is turned off.
ABS control can be observed by vibration of
the brake pedal and noise. You should never
expect the ABS to reduce the braking dis-
tance under any circumstances. This distance
will increase when driving on gravel, recent
snow or on icy or slippery ground.
Brake assist system (BAS)
The brake assist system may reduce the re-
quired braking distance. The brake assist
system boosts the braking force if you press
the brake pedal quickly in an emergency. As
a result, the braking pressure increases rap-
idly, the braking force is multiplied and the
braking distance is reduced. This enables the »1)

Do not lift your foot off the brake pedal!
When the brake pedal is released or when
the brake force is reduced, braking assist au-
tomatically turns off the brake servo.
Traction control system (ASR) or Traction
Control (TC)*
In the event of wheelspin, the traction control
system ASR or TC reduces the engine torque
to match the amount of grip available. The
ASR or TC makes some situations easier, for
example, when starting, accelerating or go-
ing uphill, even in unfavourable road condi-
tions.
Electronic differential lock (EDS)
EDL is available when driving in straight lines
under normal conditions. When the EDL de-
tects wheelspin, it brakes the spinning wheel
and directs the power to the other one. To
prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The EDL
will switch on again automatically when the
brake has cooled down. WARNING
Driving at high speed on icy, slippery or wet
grou nd c

an result in loss of vehicle control and serious injury to the driver and passen-
ger
s.
● Adju

st your speed and driving style to visi-
bility
, road, traffic and weather conditions.
Even though the brake assist systems, ABS,
BAS, EDL, ASR and ESC* provide more securi-
ty, do not take unnecessary risks while driv-
ing.
● Brake assist systems can not overcome the
law
s of physics. Even with ESC* and other
systems, slippery and wet roads will always
be dangerous.
● Driving to quickly on wet ground can result
in the wheels lo
sing contact with the ground
in an effect known as “aquaplaning”. Without
adherence, it is impossible to brake, steer or
control the vehicle.
● Brake assist systems cannot avoid acci-
dents if
, for example, the driver does not re-
spect safety distances or drives to quickly in
difficult conditions.
● Even though brake assist systems are ex-
tremely eff
ective and help control the vehicle
in difficult situations, remember that the ve-
hicle stability depends on tyre grip.
● When accelerating on a slippery surface,
for ex
ample on ice or snow, press the acceler-
ator carefully. The wheels can still slip even
with brake assist systems resulting in loss of
vehicle control. WARNING
The effectiveness of the ESC* can be consid-
erab ly

reduced if other components and sys-
tems affecting driving dynamics are not main-
tained or are not functioning correctly. This
includes, among others, brakes, tyres and
other systems already mentioned.
● Remember that changing and fitting other
components
to the vehicle can affect opera-
tion of the ABS, BAS, ASR TC, EDL and ESC*.
● Changes to the vehicle suspension or using
unap
proved wheel/tyre combinations can af-
fect operation of the ABS, BAS, ASR, TC, EDL
and ESC* and their effectiveness.
● Likewise, the effectiveness of ESC* de-
pends on the u
se of suitable tyres
››› page 197. Note
● To en s

ure that the ESC*, ASR and TC work
properly, all four wheels must be fitted with
identical tyres. Any differences in the rolling
radius of the tyres can cause the system to
reduce engine power when this is not de-
sired.
● If a malfunction should occur in the ABS,
the ESC*, ASR, T
C and EDL will also be affec-
ted.
● Noises may be heard while any of the
above sy
stems are operating.148

si
s

t function)
Introduction The City Safety Assist function covers driving
s
it
uation

s at a distance of about 10 metres in
front of the vehicle, in a speed range of ap-
proximately 5-30 km/h (3-19 mph).
When the system detects a possible collision
with a vehicle in front, the vehicle prepares
for a possible emergency braking ››› .
If the driv
er doe

s not react to an imminent
collision, the system can automatically brake
the vehicle in order to reduce speed faced
with a possible collision. The system can
help to reduce the consequences of an acci-
dent.
If the City Safety Assist function determines
that the driver has braked insufficiently when
faced with an imminent collision, the system can increase the brake force in order to re-
duce speed.

The system can help to reduce
the consequences of an accident. WARNING
The smart technology in the City Safety As-
si s

t system cannot change the limits imposed
by the laws of physics and by the system it-
self. The increased convenience offered by
the City Safety Assist system should never
prompt you to take risks. The driver always
assumes the responsibility of braking in
time.
● The City Safety Assist function cannot pre-
vent ac
cidents or serious injury by itself.
● The City Safety Assist system may carry out
unw
anted brake interventions in complex
driving situations e.g. when a vehicle crosses
at a short distance. WARNING
Relying on the City Safety Assist system in
city driv

ing as part of one's driving behaviour
may cause accidents and serious injury. The
system is not a replacement for driver aware-
ness.
● Always adapt your speed and the distance
to the v
ehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● The City Safety Assist function does not re-
act to peop
le, animals or vehicles that cross or move in the opposite direction in the same
lane.
●
If af

ter switching on the City Safety Assist
function the
vehicle begins to move, slow the
vehicle with the foot brake. CAUTION
If you suspect that the City Safety Assist ra-
d ar f e

ature is damaged, switch it off. This will
avoid additional damage.
● Any repair of the radar sensor requires spe-
cia
list knowledge. SEAT recommends taking
your car in for technical service. Note
● If the C ity

Safety Assist function activates a
brake, the brake pedal range is reduced. This
makes the brake pedal seem “harder”.
● Automatic brake intervention by the City
Safety As
sist function can be cancelled by
pressing the clutch pedal, the accelerator
pedal or by a corrective intervention.
● During automatic braking by the City Safety
Assi
st function you may hear unusual noises.
This is normal and is produced in the brake
