Driving
Some tips on how to help you reduce pollu-
tion while saving money are listed below.
Active cylinder management (ACT ®
)
Depending on the equipment, the vehicle
may have active cylinder management
(ACT ®
).
The active cylinder management (ACT ®
) may
automatically deactivate some of the engine
cylinders if the driving situation does not re-
quire too much power. When it is switched
off, no fuel is injected into these cylinders,
hence total fuel consumption may be re-
duced.
Drive anticipating the traffic situation
A vehicle uses most fuel when accelerating.
When you anticipate situations, you have to
brake less often and, thus, accelerate less. If
it is possible, let the vehicle roll with a gear
engaged , for example, if you see a red light
ahe a
d. The braking effect achieved in this
way helps to reduce the wear of brakes and
tyres; emissions and fuel consumption are
reduced to zero (disconnection due to iner-
tia).
Change gear early to save energy
An effective way of saving fuel is to change
up
quickly through the gears. Running the
engine at high rpm in the lower gears uses
an unnecessary amount of fuel. Manual gearbox:
shift up from first to second
gear as soon as possible. We recommend
that, whenever possible, you change to a
higher gear upon reaching 2000 rpm. Follow
the “recommended gear” indication that ap-
pears on the instrument panel ››› page 64.
Avoid driving at high speed
We advise you not to drive at the top speed
permitted by the vehicle. Fuel consumption,
exhaust emissions and noise levels all in-
crease very rapidly at higher speeds. Driving
at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine
when waiting in a traffic jam, at level cross-
ings or at traffic lights with a long red phase.
The fuel saved after only 30 - 40 seconds is
greater than the amount of fuel needed to re-
start the engine.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high dur-
ing this initial warm-up phase. It is therefore
best to drive off immediately after starting
the engine. Avoid running the engine at high
speed.
Periodic maintenance
Periodic maintenance work guarantees that,
before beginning a journey, you will not con- sume more than the required amount of fuel.
A well-serviced engine gives you the benefit
of
improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale val-
ue.
A badly serviced engine can consume up to
10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of
polluting exhaust gases, the engine and the
exhaust gas filtration systems should reach
the optimum operating temperature.
With the en

gine cold, fuel consumption is
proportionally higher. The engine does not
warm up and fuel consumption does not nor-
malise until having driven approximately four
kilometres (2.5 miles). This is why we recom-
mend avoiding short trips whenever possi-
ble.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an ad-
equate pressure saves fuel. If the tyre pres-
sure is just one bar (14.5 psi/100 kPa) too
low, fuel consumption can increase by as
much as 5%. Due to the greater rolling resist-
ance, under-inflation also increases tyre wear
wear and impairs handling.
The tyre pressures should always be checked
when the tyres are cold.

The essentials

Operation
Do not use winter tyres all year round as they
increase fuel consumption by up to 10%.
Avoid unnecessary weight
Given that every kilo of extra weight will in-
c r
ease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing transported.
A roof rack is often left in place for the sake
of convenience, even when it is no longer
needed. At a speed of 100 km/h (62 mph)
and 120 km/h (75 mph) your vehicle will use
about 12% more fuel as a result of the extra
wind resistance caused by the roof rack even
when it is not in use.
Save electricity
The engine activates the alternator, which
produces electricity. With the need for elec-
tricity, fuel consumption also increases. Be-
cause of this, always turn off electrical devi-
ces when you do not need them. Examples of
devices that use a lot of electricity are: the
blower at high speeds, the rear window heat-
ing or the seat heaters*. Note
● If your vehicle has Start-Stop, it is not rec-
ommended th at

you switch this function off. ●
It is recommended that you close the win-
dows when driving at more than 60 km/h
(37 mph)
● Do not driv

e with your foot resting on the
clutch pedal
, as the pressure can make the
plate spin, more fuel will be used and it can
burn the clutch plate lining, causing a serious
fault.
● Do not hold the car on a hill with the clutch,
use the foot brake or hand brake, using the
latter to start. The fuel consumption will be
lower and you will prevent the clutch plate
from being damaged.
● On descents, use the engine brake, chang-
ing to the gear that is more suitable for the
slope. Fuel consumption will be “zero” and
the brakes will not suffer. Driving abroad
To drive abroad, the following must be taken
into consideration:
●
For vehicles fitted with a catalytic converter
ensure that unleaded petrol is available for
the journey. See the chapter “Refuelling”. Au-
tomobile organisations will have information
about service station networks selling unlea-
ded fuel.
● In some countries, it is possible that your
car model is 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.
Adhesive strips for headlights
In countries where vehicles drive on the other
side of the road to your home country, the
asymmetric dipped beam may dazzle drivers
of oncoming vehicles.
To prevent dazzling, you must apply stickers
to certain parts of the headlight lenses. Fur-
ther information is available at any Technical
Service.
In vehicles with adaptive headlights, the ro-
tation system must previously be disconnec-
ted. To do this, please go to a specialised
workshop.

Braking and stability systems Electronic Stability Control (ESC)* Fig. 140
Detailed view of the dash panel: ESC
switch. This Electronic Stability System reduces the
risk of skidding and improves the vehicle's
stability and ability to hold the road.
The Electronic Stability Control (ESC) contains
the electronic differential lock (EDL) and the
traction control system (ASR). The ESC works
together with the ABS. Both control lamps
will light up if the ESC or ABS systems are
faulty.
The ESC system is started automatically
when the engine is started. The ESC system is always active and cannot
be switched off. The ESC switch only switches
the ASR off.
The ASR can be deactivated when wheel spin
is desirable
››› page 141 .
F or e
xample:
● When driving with snow chains.
● When driving in deep snow or on loose sur-
faces.
● When the vehicle is stuck, to rock it back-
wards and forwards.
Press the button to switch the ASR back on
when you no longer need wheel spin.
Electronic Stability Control (ESC)*
The ESC reduces the risk of skidding by brak-
ing the wheels individually.
The system uses the steering wheel angle
and road speed to calculate the changes of
direction desired by the driver, and constant-
ly compares them with the actual behaviour
of the vehicle. When irregularities occur, for
example, if the vehicle begins to skid, the
ESC brakes the appropriate wheel automati-
cally.
The forces acting on the braked wheel bring
the vehicle back to a stable condition. If the
vehicle tends to oversteer (the rear end
slides out), the system will act on the front
wheel on the outside of the turn. WARNING
● Do not forget that the electronic stability
control ESC cannot defy the laws of physics.
This should be kept in mind, particularly on
slippery and wet roads and when towing a
trailer.
● Always adapt your driving style to suit the
condition of the roads and the traffic situa-
tion. The greater safety provided by the ESC
should not encourage you to run any risks. CAUTION
● To ensure that the ESC works correctly, all
four wheels must be fitted with the same
tyres. Any differences in the rolling radius of
the tyres can cause the system to reduce en-
gine power when this is not desired.
● Any modifications made to the vehicle (for
example, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS, EDL, ESC and ASR. Electronic differential lock (EDL)*
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. In case of an EDL fault,

pressure to this wheel. The driver is made
aware of this control process by a pulsating
of the brake pedal and audible noise. This is
a deliberate warning to the driver that one or
more of the wheels is tending to lock and the
ABS control function has intervened. In this
situation it is important to keep the brake
pedal fully depressed so the ABS can regu-
late the brake application. Do not “pump”.
If you brake hard on a slippery road surface,
the best possible control is retained as the
wheels do not lock.
However, ABS will not necessarily guarantee
shorter braking distances in all conditions.
Br ak
ing distance could even be further if you
brake on gravel or on fresh snow on a slip-
pery surface. WARNING
● The anti-lock brake system cannot defy the
laws of physics. Slippery and wet roads are
dangerous even with ABS! If you notice that
the ABS is working (to counteract locked
wheels under braking), you should reduce
speed immediately to suit the road and traffic
conditions. Do not let the extra safety fea-
tures tempt you into taking any risks when
driving.
● The effectiveness of ABS is also determined
by the tyres fitted ››› page 176.
● If the ru

nning gear or brake system is modi-
fied, the effectiveness of the ABS could be se-
verely limited. Traction control system (ASR)*
The traction control system prevents the driv-
en wheels from spinning when the vehicle is
accelerating. This system always includes
ABS.
Description and operation of the traction
control system during acceleration (ASR
On front-wheel drive vehicles, the ASR sys-
tem intervenes, reducing engine power and
preventing the driven wheels from slipping
during acceleration. The system works in the
entire speed range in conjunction with ABS.
If a failure occurs in the ABS, the ASR will al-
so stop working.
TCS helps the car to start moving, accelerate
and climb a gradient in slippery conditions
where this may otherwise be difficult or even
impossible.
The ASR automatically switches on when the
engine is started. If necessary, it may be
turned on or off by briefly pressing the ESC
button on the centre console.
When the ASR is off, the warning lamp lights
up . The ASR should normally be left on.
Only in exceptional circumstances, when
wheel spin is required, can they be turned off
using the ESC button, for example:
●
With compact temporary spare wheel.
● When using the snow chains. ●
When driving in deep snow or on soft ter-
rain.
● When the vehicle is bogged-down, to free it
“by rocking it.”
The ASR should be switched on again as
soon as possible. WARNING
● Remember that not even the ASR can defy
the laws of physics. This should be kept in
mind, particularly on slippery and wet roads
and when towing a trailer.
● Always adapt your driving style to suit the
condition of the roads and the traffic situa-
tion. The greater safety provided by the ASR
should not encourage you to run any risks. CAUTION
● To ensure that the ASR works correctly,
identical tyres should be fitted on all four
wheels. Any differences in the rolling radius
of the tyres can cause the system to reduce
engine power when this is not desired.
● Any modifications made to the vehicle (for
example, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS and ASR. 141

Operation
XDS* When taking a curve, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In
this way, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise,
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected.
Brake servo The brake servo increases the pressure you
apply to the brake pedal. It works
only when
the engine is running . If the brake servo is not functioning, e.g. due
to a malfunction, or if the vehicle is being
towed, you will have to press the brake pedal
considerably harder to make up for the lack
of servo assistance.
WARNING
The braking distance can also be affected by
external factors.
● Never let the vehicle coast with the engine
switched off. Failure to follow this instruction
could result in an accident. The braking dis-
tance is increased considerably when the
brake servo is not active.
● If the brake servo is not working, for exam-
ple when the vehicle is being towed, you will
have to press the brake pedal considerably
harder than normal. Start-Stop System*
Description and operation The Start-Stop function stops the engine
when the vehicle is stopped and starts it au-
tomatically when required.
– When the vehicle is stopped, put it in neu-
tral and release the clutch pedal. The en-
gine will stop.
– When the clutch pedal is pressed, the en-
gine starts again. –
The instrument panel display shows infor-
mation about the status of the Start-Stop
function ››› Fig. 142 .

Start-Stop function interruption
In the following situations, the Start-Stop
function will be interrupted and the engine
will automatically start:
● The vehicle starts moving.
● The brake pedal is pressed several times in
a row.
● The battery has been discharged excessive-
ly.
● The Start-Stop System is manually deacti-
vated.
● The windscreen de-mist function is turned
on.
● The temperature of the interior exceeds the
comfort limits ( A/C button).
● If the airflow is increased by more than 3
presses.
● Temperature setting HI or LO is selected.
● The engine coolant temperature is insuffi-
cient.
● The alternator is faulty, for example the V-
belt has ruptured.
● If any of the conditions described in the
previous section are not fulfilled. WARNING
Never allow the vehicle to move with the en-
gine off for any reason. You could lose control
of your vehicle. This could cause an accident
and serious injury. ●
The brake servo does not work with the en-
gine off. You need more force to stop the vehi-
cle.
● Power steering does not work when the en-
gine is not running. That is why it is much
more difficult to turn the steering wheel.
● Turn off the Start-Stop system when driving
through water (fording streams, etc.). Note
● For vehicles with the Start-Stop function
and a manual gearbox, when the engine is
started, the clutch must be pressed.
● When the conditions for the Start-Stop
function are not fulfilled, the instrument pan-
el displays the Start-Stop indicator dimmed.
● If the steering wheel is turned more than
270°, it will not be possible to start the vehi-
cle again. To start the vehicle, straighten the
steering wheel so that it is turned less than
270°. Activating and deactivating the Start-

Operating and safety warnings WARNING
● The Rear Assist does not make it possible
to precisely calculate the distance from ob-
stacles (people, vehicles, etc.) and nor can it
overcome the system's own limits, hence us-
ing it may cause serious accidents and inju-
ries if used negligently or without due care.
The driver should be aware of his/her sur-
roundings at all times to ensure safe driving.
● The camera lens expands and distorts the
field of vision and displays the objects on the
screen in a different, vague manner. The per-
ception of distances is also distorted by this
effect. ●
Some objects may, due to the resolution of
the display screen - not be displayed in a sat-
isfactory manner or may not be displayed at
all. Take special care with thin posts, fences,
railings or trees that might not be displayed
on screen and could damage the vehicle.
● The rear assist has blind spots where it is
not possible to represent people or objects
(small children, animals and certain objects
cannot be detected in its field of vision). Mon-
itor the vehicle's surrounding area at all
times.
● Keep the camera lens clean, free of ice and
snow, and do not cover it.
● The system is not a replacement for driver
awareness. Supervise the parking operation
at all times, as well as the vehicle's surround-
ing area. Adapt your speed and driving style
at all times to suit visibility, weather, road
and traffic conditions.
● Do not be distracted from the traffic by
looking at the screen.
● The images on the rear assist screen are
only two-dimensional. Due to a lack of spatial
depth, protruding parts or holes in the road,
for example, are more difficult to detect or
may not be seen at all.
● Vehicle load modifies the representation of
the orientation lines displayed. The width
represented by the lines diminishes with ve-
hicle load. Pay special attention to the vehi-
cle's surroundings when the inside of the ve-
hicle of the luggage compartment is carrying
a heavy load. 144

● The system switches off 8 seconds after
disengaging reverse gear (manual gearbox)
or removing the selector lever from the R po-
sition (automatic gearbox). The system will
also disconnect immediately after the igni-
tion is switched off.

Parking manoeuvre
● Place the vehicle in front of the parking
space and engage reverse gear (manual
gearbox) or move the selector to the R posi-
tion (automatic gearbox).
● Reverse slowly, and turn the steering wheel
so that the side orientation lines lead to-
wards the parking space.
● Guide the vehicle into the parking space so
that the side orientation lines run parallel to
it. 1 2

General information Various aid systems are in place to help in
parking and manoeuvring depending on the
vehicle’s equipment:
The rear parking aid
is an audible aid that
w

arns against obstacles behind the vehicle
››› page 147.
The front parking aid i
s an audible aid that
warns against obstacles both behind and in
front of the vehicle ›››
page 148.
Apart from the acoustic signals, when the ve-
hicle is equipped with a portable navigator
(PND), this visually displays information re-
garding front and/or rear areas. WARNING
● The sensors have blind spots in which ob-
stacles may not be detected.
● Always look out for small children and ani-
mals because the system will not always de-
tect them. Pay attention when reversing to
avoid accidents.
● The parking aid is not a replacement for
driver awareness. The driver must take full re-
sponsibility for parking and other manoeu-
vres. 146
