Run-in and economical driving R u
nnin
g in a new engine The engine needs to be run in over the first
1,500 km.
Up t
o 1000 k

ilometres
– Do not drive at speeds of more than 2/3
the maximum s

peed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1000 t o 1500 k

ilometres (600 to 900
miles)
– Speeds can be gradual
ly increased to the
maximum road speed or maximum permis-
sible engine speed (rpm).
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 in. For the sake of the environment
If the engine is run in gently, its life will be in-
cr e

ased and its oil consumption reduced. Tyre and brake pad run-in
New tyres should be run-in carefully for the
firs
t

500 km (300 miles). New brake pads
should be run-in carefully for the first
200 km.
During the first 200 km, you can compensate
for the reduced braking effect by applying
more pressure to the brake pedal. In case of
a sharp braking, the braking distance will be
longer with new brake pads than with brake
pads which have been run-in. WARNING
● At fir s

t, new tyres do not give maximum
grip, and require running-in. This may cause
an accident. Drive particularly carefully in the
first 500 km.
● New brake pads must be “run in” and do
not hav
e the correct friction properties during
the first 200 km. However, the reduced brak-
ing capacity may be compensated by press-
ing on the brake pedal a little harder. Environmental compatibility
Environmental protection is a top priority in

● Incr

eased use of single-grade materials.
● Plastic parts and elastomers are marked in
accor
dance 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 c
omponents are not easily separated.
● Use of recycled materials and/or materials
originating fr
om renewable sources.
● Reduction of volatile components, includ-

metals, with the exceptions
dictated by law (Annex II of ELV Directive
2000/53/EC): cadmium, lead, mercury, hexa-
valent chromium.
Manufacturing methods
● Reduction of the quantity of thinner in the
protectiv
e wax for cavities.
● Use of plastic film as protection during ve-
hicle tr

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 oc

cur ››› page 100. 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. WARNING
The catalytic converter reaches very high
temper at

ures! Risk of fire!
● Never park where the catalytic converter
coul
d come into contact with dry grass or
flammable materials under the vehicle.
● Do not apply additional underseal or anti-
corro
sion coatings to the exhaust pipes, cata-
lytic converter or the heat shields on the ex-
haust system. These materials could catch
fire when the vehicle is being driven. 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

e Filter) if the vehicle data sticker (back
cover of the “Maintenance Programme”) lists
the code PR 7GG ››› Fig. 173.
The diesel engine particulate filter eliminates
most of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. If this is not possible (for ex-
ample, multiple short trips) the filter will be
obstructed by soot and  the diesel engine
particulate filter warning lamp will light up.
This does not represent a fault, it is a warning
that indicates that the filter has not been
able to regenerate automatically and that you

page 101. WARNING
● The diesel en

gine particulate filter may
reach extremely high temperatures; the vehi-
cle should be parked so that the exhaust pipe
does not come into contact with flammable
materials underneath the vehicle. Otherwise
there is a risk of fire. CAUTION
● Your v

ehicle is not designed to use biodie-
sel fuel. Never, under any circumstances re-
fuel with biodiesel. The use of biodiesel fuel
could damage the engine and the fuel sys-
tem. The addition of biodiesel to diesel by
the diesel producer in accordance with stand-
ard EN 590 is authorised and will not cause
damage to the engine or the fuel system.
● Using diesel fuel with a high sulphur con-

gFuel consumption, environmental pollution
and w
e
ar t

o the engine, brakes and tyres de-
pends in large part on your driving style. By
adopting an economical driving style and an- ticipating the traffic situation ahead, you can
eas

ily reduce fuel consumption by 10-15%.
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. The number of active cylinders can be
seen on the instrument panel display
›››  page 30.
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
ahead. 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 w
ay 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 159.
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
s peed.
P eriodic
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 engine 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.
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-
crease 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 y

our vehicle has Start-Stop, it is not rec-
ommended that 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 drive with your foot resting on the
clutc
h 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 g
ear that is more suitable for the
slope. Fuel consumption will be “zero” and
the brakes will not suffer. Driving abroad

Driver assistance systems
● In some c ou
ntrie
s, 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. Driver assistance systems

Connecting/disconnecting ESC and
ASR The ESC is switched on automatically when
the engine i
s

started, and only works when
the engine is running and includes the ABS,
EDS and ASR systems.
The ASR and ESC function should only be
switched off in situations in which traction is
insufficient, among others:
● When driving in deep snow or on surfaces
that ar

e not very firm.
● To “free” the vehicle if it gets stuck.
Then switc
h the ASR and ESC function back

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 Stability Control (ESC)*
This Electronic Stability System reduces the
ri
sk
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 switc

hed off. With the Easy Connect sys-
tem it is only possible to deactivate the ASR
or else select Sport mode.
The ASR can be deactivated when wheel spin
is desirable ››› page 172.
For example:
● When driving with snow chains.
● When driving in deep snow or on loose sur-
face
s.
● When the vehicle is stuck, to rock it back-
ward
s 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 f or

get 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 r
oads and the traffic situa-
tion. The greater safety provided by the ESC
should not encourage you to run any risks. CAUTION
● To en s

ure 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
examp
le, 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 (EDS)*
EDL helps the vehicle to start moving, accel-
er

e and c

limb a gradient in slippery condi-
tions where this may otherwise be difficult or
even impossible.

pressure to this wheel. The driver is made
a w
ar
e 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.
Braking distance could even be further if you
brake on gravel or on fresh snow on a slip-
pery surface. WARNING
● The anti-lock br

ake 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 ty
res fitted ››› page 212.
● If the running gear or brake system is modi-
fied, the effectivene
ss of the ABS could be se-
verely limited. Traction control system (ASR)*
The traction control system prevents the driv-
en wheels
fr

om 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 could be
connected or disconnected by means of the
Easy Connect system.
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 drivin g in deep s

now or on soft ter-
rain.
● When the vehicle is bogged-down, to free it
“by r
ocking it.”
The ASR should be switched on again as
soon as possible. WARNING
● Remember th at

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 r
oads and the traffic situa-
tion. The greater safety provided by the ASR
should not encourage you to run any risks. CAUTION
● To en s

ure 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
examp
le, 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. 172

Driver assistance systems
Electronic differential lock (XDS)* When taking a curve, the driveshaft differen-
tial
mec
hanism 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 or the ESC is
in Sport mode.
Brake servo The brake servo increases the pressure you
ap
p
ly

to the brake pedal. It works only when
the engine is running . If the brake servo is not functioning, e.g. due
to a malf

unction, 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
ext ern

al factors.
● Never let the vehicle coast with the engine
switc
hed 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*
