2015 Seat Altea fuel consumption

Operation
●
Do not apply additional underseal or anti-
corrosion 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-
cause the irregularity 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
working 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 engine particulate filter*
Fig. 130
Vehicle data sticker on back cover of
the Maintenance Programme. Your vehicle is fitted with a DPF (Diesel partic-
ulate filter) if the vehicle data sticker (back
cover of the “Maintenance Programme)” lists
the PR code 7GG or 7MG
››› Fig. 130 .
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. 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
must perform a cleaning cycle, as indicated
in ››› page 41
. WARNING
● The diesel engine 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 vehicle 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-
tent may significantly reduce the useful life of
the diesel particulate filter. Your Technical
Service will be able to tell you which coun-
tries have diesel with a high sulphur content. Economical and environmentally
friendly driving
Fuel consumption, environmental pollution
and wear to 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
easily reduce fuel consumption by 10-15%.

Driving
Some tips on how to help you reduce pollu-
tion while saving money are listed below.
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 47.
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. This is why we recommend avoid-
ing short trips whenever possible.
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
and impairs handling.
The tyre pressures should always be checked
when the tyres are cold.
Do not u

se 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) »

Operation
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 is also increased.
Because of this, always turn off electrical de-
vices when you do not need them. Examples
of devices that use a lot of electricity are: the
fan at high speeds, the rear window heating
or the seat heaters*. Note
● If you vehicle has Start-Stop, it is not rec-
ommended t o sw
itch this function off.
● It is recommended to close the windows
when driving at more than 60 km/h
● Do not drive with your foot resting on the
clutch pedal,, as the pressure can make the
pl

ate spin, more fuel will be used and it can
burn the clutch plate lining, causing a serious
fault.
● Do not hold the vehicle on a hill with the
clutch, use the foot brake or hand brake, us-
ing 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.
Driver assistance systems
Braking and stability systems Electronic Stability Control (ESC)* Fig. 131
Detailed view of the centre console:
ESC switch. This Electronic Stability System reduces the
risk of skidding and improves the vehicle's
stability and ability to hold the road.
Electronic Stability Control (ESC) includes the
electronic differential lock (EDL), the traction
control system (TCS), the brake assist system
(BAS) and the trailer stabilisation programme
(TSP). 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.

Checking and refilling levels
●
When filling the fuel tank after having run it
completely dry on a vehicle with a diesel en-
gine the ignition must be switched on for at
least 30 seconds before starting the engine.
Subsequently, when you start the engine it
may take longer than normal to start firing
(up to one minute). This is due to the fact that
the fuel system has to purge itself of air be-
fore starting. For the sake of the environment
Do not try to put in more fuel after the auto-
matic filler nozzle has switched off; this may
cause the fuel to overflow if it becomes warm. Petrol
Petrol types The recommended fuel types are listed on a
sticker inside the fuel tank flap.
Only
unleaded petrol conforming to standard
DIN EN 228 may be used for vehicles with
c at
alytic converters (EN = “European Stand-
ard”).
Petrol types are categorised according to
their
octane number, e.g. 91, 95, 98 RON
(RON = “research octane number”). You may
use petrol with a higher octane number than
the one recommended for your engine. How- ever, this has no advantage in terms of fuel
consumption and engine power. CAUTION
● Petrol with standard EN 228 may be mixed
with small quantities of ethanol. However,
the so-called “bioethanol fuels” available at
commercial establishments with reference
E50 or E85, which contain a high percentage
of ethanol, may not be used, as they will
damage the fuel system.
● Even one tankful of leaded fuel would per-
manently impair the efficiency of the catalyt-
ic converter.
● High engine speed and full throttle can
damage the engine when using petrol with an
octane rating lower than the correct grade for
the engine. For the sake of the environment
Just one full tank of leaded fuel would seri-
ously impair the efficiency of the catalytic
converter. Petrol additives
The quality of the fuel influences the behav-
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the
petrol industry, free of metals. These addi-
tives will help to prevent corrosion, keep thefuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives is not available or engine problems
arise, the necessary additives must be added
when refuelling.
Not all petrol additives have been shown to
be effective. The use of unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings.
SEAT recommends “genuine Volkswagen
Group fuel additives for petrol engines”.
These additives can be bought at SEAT Au-
thorised Services, where information on how
to use them can also be obtained.
CAUTION
Do not refuel if the filler indicates that the
fuel contains metal. LRP (lead replacement
petrol) fuels contain high concentrations of
metal additives. Using them may damage the
engine! 159

Advice
●
At continuously high speeds, a tyre with in-
sufficient pressure flexes more. In this way it
becomes too hot, and this can cause tread
separation and tyre blow-out. Always observe
the recommended tyre pressures.
● If the tyre pressure is too low or too high,
the tyres will wear prematurely and the vehi-
cle will not handle well. Risk of accident! For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. Tyre pressure monitoring
The tyre pressure monitoring system con-
stantly checks the pressure of the tyres.
The system uses the speed sensors of the
ABS wheels. It operates by analysing the
speed and frequency spectrum of each
wheel.
For optimum performance, use genuine SEAT
tyres. In addition, check and adjust tyre pres-
sures regularly.
Whenever the tyre pressure is are changed or
one or more tyres are changed, the system
should be reset by pressing the SET button
on the centre console.
The system warns the driver in the event of a
loss of pressure by means of symbols and messages in the instrument panel display.
The system operates via the ESC
››› page 134.
Note that tyre pressure also depends on tyre
temperature. Said pressure increases around
0.1 bar (2.9 psi/10 kPa) for each +10 °C
(+50 °F) in tyre temperature increase. The tyre
heats up while the vehicle is being driven
and the tyre pressure will rise accordingly.
Therefore, you should only adjust the tyre
pressure when they are cold (i.e. approxi-
mately at ambient temperature).
To ensure that the tyre pressure monitoring
system works reliably, you should check and,
if necessary, adjust the tyre pressures at reg-
ular intervals and store the correct pressures
(reference values) in the system.
A tyre pressure information label is attached
to the inside of the fuel tank flap. WARNING
● Never adjust tyre pressure when the tyres
are hot. This may damage or even burst the
tyres. Risk of accident!
● An insufficiently inflated tyre flexes a lot
more at high speeds and causes significant
heating of the tyre. Under these conditions,
the tyre bead may be released or the tyre may
burst. Risk of accident! For the sake of the environment
Under-inflated tyres lead to increased fuel
consumption and tyre wear. Significant tyre pressure loss
The tyre symbol
 is displayed and indicates
th at
the tyre pressure of at least one tyre is
insufficient.
– Stop the vehicle.
– Switch the ignition off.
– Check the tyre(s).
– Change the wheel if necessary.

Emergencies
handle better when the roads are free of
snow and ice.
If you have a flat tyre, please refer to the
notes on the spare wheel ››› page 179, New
tyres and wheels .WARNING
The maximum speed for the winter tyres must
not be exceeded. Otherwise, this could lead
to damage and risk of accident. For the sake of the environment
Fit your summer tyres again as soon as possi-
ble. They are quieter, do not wear so quickly
and reduce fuel consumption. Snow chains
Snow chains are only permitted on front
wheels and only for tyres 195/65R15 and
205/55R16. These tyres may only be fitted
with fine-pitch link chains which do not pro-
trude more than 15 mm
›››
page 210.
Other tyres may use fine-pitch links which do
not protrude more than 9 mm, including ten-
sion device.
Remove wheel hub covers and trim rings be-
fore fitting snow chains. For safety reasons,
cover caps, available at any technical service,
must then be fitted over the wheel bolts. All-wheel drive
: where snow chains are com-
pulsory, this normally also applies to all-
wheel drive vehicles. Snow chains may only
be fitted to the front
wheels (also on vehicles
w
ith all-wheel drive). WARNING
Snow chains should be correctly tightened in
accordance with the manufacturer's instruc-
tions. This will prevent the chains coming in-
to contact with the wheel housing. CAUTION
Remove the snow chains to drive on roads
without snow. Otherwise they will impair
handling, damage the tyres and wear out very
quickly. Note
● In some countries, the maximum permitted
speed with snow chains is 50 km/h (31 mph).
The legal requirements of each country must
be followed.
● We recommend that you ask your technical
service for information about appropriate
wheel, tyre and snow chain size. Emergencies
