al level.
Check tyre pressure
Always make sure the tyres are inflated to the
correct pressures ››› page 280 to save fuel. If
the pressure is below half bar, fuel consump-
tion may increase by 5%. Due to the greater
rolling resistance, under-inflation also increa-
ses tyre wear and impairs handling.
Do not use winter tyres all year round as they
increase fuel consumption by up to 10%.
Avoid carrying unnecessary loads
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.
Since the luggage rack increases the aerody-
namic drag of the vehicle, you should remove
it when not needed. At speeds of 100-120
km/h (62-75 mph), this will save 12% of fuel.
Save electrical energy
The engine drives the alternator, thereby gen-
erating electricity. This implies that any in-
crease in power consumption also increases
fuel consumption! For this reason, switch off
any unneeded electrical devices. Devices that
use a lot of electricity includes the blower at a high setting, the rear window heating or
the seat he
ating*.
Power management This sy
stem helps to ensure reliable
starting The power management controls the distribu-
tion of el
ectric

al energy and thus helps to en-
sure that there is always enough power avail-
able to start the engine.
If a vehicle with a conventional electrical sys-
tem is left parked for a long time, the battery
will gradually lose its charge because certain
electrical devices, such as the electronic
gearbox lock continues to draw current even
when the ignition is off. In some cases there
may not be enough power available to start
the engine.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy. This signifi-
cantly improves reliability when starting the
engine, and also prolongs the useful life of
the battery.
The main functions incorporated in the power
management system are battery diagnosis,
residual current management and dynamic
power management. Battery diagnosis
The batt
er

y diagnosis function constantly
registers the condition of the battery. Sen-
sors detect the battery voltage, battery cur-
rent and battery temperature. This enables
the system to calculate the current power lev-
el and charge condition of the battery.
Residual current management
The residual current management reduces
power consumption while the vehicle is
parked. It controls the supply of power to the
various electrical devices while the ignition is
switched off. The system takes the battery di-
agnosis data into consideration.
Depending on the power level of the battery,
switch off the individual electrical devices
one after the other to prevent the battery
from losing too much charge and to ensure
that the engine can be started reliably.
Dynamic power management
While the vehicle is moving, this function dis-
tributes the available power to the various
electrical devices and systems according to
their requirements. The power management
ensures that on-board systems do not con-
sume more electrical power than the alterna-
tor can supply, and thus maintains the maxi-
mum possible battery power level. »

hazard! Note
While the control lamps , ,  or  r
e-
m ain lit, ther

e may be engine problems, fuel
consumption may increase and the engine
may lose power. Catalytic converter
3 App
lies to vehicles with petrol engine
The
vehicle must only be used with unleaded
petrol, otherwise the catalytic converter will
be irreparably damaged.
Never drive until the tank is empty; an irregu-
lar supply of fuel can cause faulty combus-
tion. In these cases, unburned fuel reaches
the exhaust system, which can overheat and
damage the catalytic converter.
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 benoticed because the engine idle speed in-
cr
e

ases 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 fil-
ter to burn. On completion of the cleaning
the warning lamp 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-

is equipped with a particulate filter, the sul-
phur c ont
ent
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).
Water in the fuel filter 1)
If your vehicle has a diesel engine and is
equipped with a fuel filter with a water sepa-
rator, the instrument panel may display the
following warning:  Water in the
fuel filter. If this is the case, take the
vehicle to a specialised workshop so that
they can drain the fuel filter. 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 s

pecialised workshop. If water is allowed
to collect in the filter, this can cause engine
performance problems. Natural gas
Natural gas can be compressed or in liquid
form, a
d

dition to others.
Liquefied natural gas (LNG) is the result of
heavy cooling of natural gas. Therefore its
volume is considerably reduced compared
with compressed natural gas (CNG). In vehi-
cles with a natural gas engine, liquefied nat-
ural gas cannot be directly refilled, as the gas
would expand excessively in the vehicle gas
tank.
Therefore, vehicles with a natural gas engine
must only be refuelled using compressed
natural gas ››› .
Nat ur
a

l gas quality and consumption
Natural gas is divided into the groups H and
L depending on its quality.
Gas type H has a superior heating power and
inferior nitrogen and carbon dioxide content
than type L. The higher the heating power of the natural gas, the lower the consumption
wil

l be.
However, the heating power and the propor-
tion of nitrogen and carbon dioxide can fluc-
tuate within the quality groups. Therefore, ve-
hicle consumption can also vary when using
a single type of gas only.
The engine management automatically
adapts to the natural gas used according to
its quality. Therefore, different quality gases
can be mixed in the tank, without the need
for comprehensive draining before applying a
different quality gas.
Updated information relating to natural gas
quality is displayed on the instrument panel
›››  page 36.
Natural gas and safety
If you can smell gas or suspect that there is a
leak ››› :
● Stop the vehicle immediately.
● Switch the ignition off.
● Open the doors to appropriately ventilate
the v
ehic

le.
● Extinguish cigarettes immediately.
● Move away from the vehicle or switch off
obj
ects that may cause sparks or a fire. 1)

Advice
Service life of tyres Fig. 250
Location of the tyre pressure sticker. Correct inflation pressures and sensible driv-
in
g h
ab
its will increase the useful life of your
tyres.
– Check tyre pressure at least once a month,
and also prior to an

y long trip.
– The tyre pressure should only be checked
when the tyre

s are cold. Do not reduce the
pressure of warm tyres.
– Adjust tyre pressure to the load being car-
ried by the

vehicle. –
In vehic
les with a tyre pressure indicator,
save the modified tyre pressure
››› page 283.
– Avoid fast cornering and hard acceleration.
– Inspect the tyres for irregular wear from
time to time.
The usef

ul life of your tyres depends on the
following factors:
Tyre pressure
Tyre pressure values are indicated on the
sticker on the inside of the fuel tank flap
››› Fig. 250.
Insufficient or excessive pressure greatly re-
duces the useful life of the tyres and adverse-
ly affects vehicle performance and ride. Cor-
rect inflation pressures are very important,
especially at high speeds.
Depending on the vehicle, tyre pressure can
be adjusted to medium load to improve driv-
ing comfort (tyre pressure ). When driving
with comfort tyre pressure fuel consumption
may increase slightly.
The tyre pressure must be adjusted according
to the load the vehicle is carrying. If the vehi-
cle is going to carry the maximum load, the
tyre pressure should be increased to maxi-
mum value indicated on the sticker on the in-
side of the fuel tank flap. Do not forget the spare wheel when checking
the tyre pr

essures: Keep this spare wheel in-
flated to the highest pressure required for the
road wheels.
In the case of a minimised temporary spare
wheel (125/70 R16 or 125/70 R18) inflate to
a pressure of 4.2 bar as indicated on the tyre
pressure label on the fuel tank flap.
Driving style
Fast cornering, heavy acceleration and hard
braking (squealing tyres) all increase tyre
wear.
Wheel balance
The wheels on new vehicles are balanced.
However, certain circumstances may lead to
imbalance (run-out), which is detected as vi-
brations in the steering wheel.
Unbalanced wheels should be rebalanced, as
they otherwise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted
or if a tyre is repaired.
Incorrect wheel alignment
Incorrect running gear alignment causes ex-
cessive tyre wear, impairing the safety of the
vehicle. If you notice excessive tyre wear, you
should check wheel alignment at a SEAT Offi-
cial Service.

regulations to this effect in your country.
“All-weather” tyres can also be used instead
of winter tyres.
Using winter tyres with V-rating
Please note that the generally applicable
240 km/h (150 mph) speed rating for winter
tyres with the letter V is subject to technical
restrictions; the maximum permissible
speed for your vehicle may be significantly
lower. The maximum speed limit for these
tyres depends directly on the maximum axle weights for your car and on the listed weight
rating of

the tyres being used.
It is best to contact a SEAT Official Service to
check the maximum speed which is permissi-
ble for the V-rated tyres fitted on your car on
the basis of this information. WARNING
Exceeding the maximum speed permitted for
the wint er ty

res fitted on your car can cause
tyre failure, resulting in a loss of control of
the vehicle – risk of accident. For the sake of the environment
Summer tyres should be fitted again as soon
as po

ssible after the winter period; they give
better handling on roads which are free of
snow and ice. Summer tyres perform with
less rolling noise, tyre wear and – most im-
portant – reduce fuel consumption. 288
