(2.5 miles), when fuel consumption will re-
t urn t
o a norm
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. »

Driving tips
Driving thr
ough flooded roadsTo prevent damage to the vehicle when driv-
in
g thr
ough w

ater, for example, along a floo-
ded road, please observe the following:
● The water should never come above the
lower edg
e of the bodywork.
● Drive at pedestrian speed. WARNING
After driving through water, mud, sludge,
etc ., the br

aking effect can be delayed slight-
ly due to moisture build-up on the discs and
brake pads. Applying the brakes carefully
several times will remove the moisture and
restore the full braking effect. CAUTION
● Drivin g thr

ough flooded areas may severely
damage vehicle components such as the en- gine, transmission, running gear or electrical
sys
t

em.
● Whenever driving through water, the Start-
Stop sys
tem* must be switched off
››› page 205. Note
● Chec k the depth of

the water before enter-
ing the flooded zone.
● Do not stop in the water, drive in reverse, or
stop the en
gine in any situation.
● Note that vehicles travelling in the opposite
direction ma
y splash water that could exceed
the maximum permitted water height for your
vehicle.
● Avoid driving through salt water (corro-
sion). Four-wheel drive
3 V
alid for vehicles: with four-wheel drive
On f
our-wheel drive models, the engine pow-
er is distributed to all four wheels
General notes
On four-wheel drive vehicles, the engine
power is distributed to all four wheels. The
distribution of power is controlled automati-
cally according to your driving style and the
road conditions. Also see ››› page 187, Brak-
ing and stability systems .The four-wheel drive is specially designed to
comp
l

ement the superior engine power. This
combination gives the vehicle exceptional
handling and performance capabilities, both
on normal roads and in more difficult condi-
tions, such as snow and ice. Even so (or per-
haps especially for this reason), it is impor-
tant to observe certain safety points ››› .
W int
er ty

res
Thanks to four-wheel drive, your vehicle will
have plenty of traction in winter conditions,
even with the standard tyres. Nevertheless,
we still recommend that winter tyres or all-
season tyres be fitted on all four wheels to
give even better braking response.
Snow chains
On roads where snow chains are mandatory,
this also applies to cars with four-wheel drive
›››  page 69.
Changing tyres
On vehicles with four-wheel drive, all four
tyres must have the same rolling circumfer-
ence. Also avoid using tyres with varying
tread depths ››› page 281.
Off-roader?
Your SEAT is not an off-road vehicle: it does
not have enough ground clearance to be
used as such. It is therefore best to avoid

Advice
Automatic car washes
B ef
or
e going through a car wash, be sure to
take the usual precautions (closing the win-
dows, roof and rear-view mirrors). If the vehi-
cle has special accessories such as spoilers
or a roof rack or two-way radio aerial, etc., it
is advisable to consult the car wash tunnel
operator.
It is best to use a car wash without revolving
bristles if possible.
Washing the vehicle with a high pressure
cleaner
When washing the vehicle with a high-pres-
sure cleaner, always follow the operating in-
structions for the equipment. This applies
particularly to the operating pressure and the
spraying distance. Do not hold the nozzle too
close to soft materials such as rubber hoses
or seals. The same applies to the parking aid
sensors*, which are located in the rear bump-
er.
Do not use a nozzle that sprays the water out
in a direct stream or one that has a rotating
jet for forcing off dirt.
Factory-fitted adhesive sheets
The following indications should be taken in-
to account to avoid damaging adhesive
sheets:
● Do not use high pressure cleaners. ●
Do not use s crapers to remove ice or snow
from the sheets.
● Do not polish the adhesive sheets.
● Do not use dirty cloths or sponges.
● It is preferable to wash them with a soft
spong
e and gentle neutral soap.
Washing the car by hand
When washing the car by hand, use plenty of
water to soften the dirt first, and rinse off as
well as possible.
Then clean the vehicle with a soft sponge,
glove or brush using only slight pressure.
You should start on the roof and work down.
Special car soap should only be used for very
persistent dirt.
Rinse the sponge or glove thoroughly and of-
ten.
Wheels, sills and similar should be cleaned
last. Use a second sponge for this. WARNING
● The v ehic

le should only be washed with the
ignition switched off. Failure to follow this in-
struction could result in an accident.
● Do not clean the underside of chassis, the
inside of
wheel arches or wheel trims without
protecting your hands and arms. You may cut
yourself on sharp-edged metal parts. Other-
wise, there is a risk of sustaining cuts. ●
When wa shin

g the car during the winter
season: water and ice in the brake system
can reduce braking effectiveness: risk of acci-
dent! CAUTION
● Do not wa

sh the vehicle in direct sunlight –
otherwise the paint can be damaged.
● Do not use sponges, abrasive household
spong
es or similar to clean insect remains.
This could damage the surface.
● Clean off stubborn dirt (insects, etc.) from
the headlight
s at regular intervals, for in-
stance when filling the fuel tank. The head-
lights should only be washed with water, do
not wipe them with a dry cloth or sponge. It
is best to use soapy water.
● Never wash tyres with a jet that sprays the
water out
in a direct stream. This could dam-
age the tyres even if the spray is kept at a
distance and only used for a very short time.
● Before washing the vehicle in an automatic
car wa
sh, please make sure to retract the ex-
terior mirrors to prevent them from being
damaged. Electrically retractable exterior
mirrors must not be folded in or out by hand,
always use the electrical power control. CAUTION
● Bef or

e washing the vehicle in an automatic
car wash, please proceed as follows to lock
the wiper arms so that they are not moved to-
wards the top of the windscreen: 258

Wheels
●
Av oid ru
nning the vehicle on tyres that are
more than 6 years old. If you have no
alternative, you should drive slowly and with
extra care at all times.
● If wheel trims are fitted after the car is pur-
cha
sed, ensure that there is an adequate flow
of air for cooling the brake system. For the sake of the environment
Old tyres must be disposed of according to
the l aw

s in the country concerned. Note
● A S EA

T Service Centre should be consulted
to find out whether wheels or tyres of differ-
ent sizes to those originally fitted by SEAT
can be fitted, and to find out about the com-
binations allowed between the front axle
(axle 1) and the rear axle (axle 2).
● Never mount used tyres if you are not sure
of their “pr
evious history”.
● For technical reasons, it is not generally
poss
ible to use the wheels from other vehi-
cles. In some cases, this may also be true for
the same model of wheel. Wheel bolts
The wheel
bolts
ar
e m
atched to the rims.
When installing different wheels (for instance
alloy wheels or wheels with winter tyres) it is
important to use the correct wheel bolts with the right length and correctly shaped bolt
head

s. This ensures that wheels are fitted se-
curely and that the brake system functions
correctly.
The wheel bolts must be clean and turn easi-
ly.
A special adapter is required to turn the anti-
theft wheel bolts* ›››

Tyre monitoring systems Introduction WARNING
Unsuitable handling of the wheels and tyres
ma y

lead to sudden tyre pressure losses, to
tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure
they are m
aintained at the pressures indica-
ted. Tyre pressure that is too low could cause
overheating, resulting in tread detachment or
even burst tyres.
● Tyre pressure should be that indicated on
the label when the ty
res are cold at all times
››› page 291.
● Regularly check the cold inflation pressure
of the tyr
es. If necessary, change the tyre
pressure of the vehicle tyres while they are
cold. ●
Re gu

larly check your tyres for damage and
wear.
● Never exceed the maximum permitted
speed or loa
ds specified for the type of tyre
fitted on your vehicle. For the sake of the environment
Under-inflated tyres lead to increased fuel
c on s

umption and tyre wear. Note
● Driv ing f

or the first time with new tyres at a
high speed can cause them to slightly ex-
pand, which could then produce an air pres-
sure warning.
● Only replace used tyres with those author-
ised by
SEAT for the corresponding type vehi-
cle.
● Do not only rely on the tyre monitoring sys-
tem. Re
gularly check your tyres to ensure
that the tyre pressure is correct and that the
tyres are not damaged due to puncture, cuts,
tears and impacts/dents. Remove objects
from the tyres only when they have not
pierced the tyres. 283

Winter service Winter ty
res –
Winter tyres must be fitted on al
l
four
wheels.
– Only use winter tyres that are approved for
your v

ehicle.
– Please note that the maximum permissible
speed for w

inter tyres may be lower than
for summer tyres.
– Also note that winter tyres are no longer ef-
fective when the

tread is worn down. –
After fittin
g the wheels you must always
check the tyre pressures. When doing so,
take into account the correct tyre pressures
listed on the rear of the front left door
frame ››› page 280.
In winter road conditions winter tyres will
considerably improve vehicle handling. The
design of summer tyres (width, rubber com-
pound, tread pattern) gives less grip on ice
and snow. This applies particularly to vehi-
cles equipped with wide section tyres or with
high speed tyres (code letters H, V or Y on
the sidewall).
Only use winter tyres of the correct type ap-
proved for your vehicle. The sizes of these
tyres are specified in the vehicle's docu-
ments (e.g. EC Certificate of Conformity or
COC 1)
). The vehicle documentation varies de-
pending on the country of residence. See al-
so ››› page 281.
Winter tyres lose a great deal of their proper-
ties when the tread is worn down to a depth
of 4 mm.
The performance of winter tyres is also se-
verely impaired by ageing, even if the tread is
still much deeper than 4 mm.
Winter tyres are subject to the following max-
imum speed limits according to speed rating
