Care and maintenance
SEAT recommends the use of car washes
without brushes.
To remove traces of wax on windows and to
prevent wiper blades from scratching, please
observe the following ››› page 128, Cleaning
windows and exterior mirrors .
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.
Start at the roof and work downwards. Spe-
cial car shampoo should only be used for
ver

y 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
Sharp components on the vehicle may cause
injury.
● Protect arms and hands from sharp edges
when cleaning the vehicle undercarriage or
the interior of the wheel hubs. WARNING
After the vehicle has been washed, the brak-
ing effect will be reduced (and the braking
distance increased) due to moisture (and ice
in winter) on the brakes.
● “Dry the brakes and remove ice” by braking
carefully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process. CAUTION
● The temperature of the water must not ex-
ceed +60 °C (+140 °F).
● To avoid damage to the paintwork, do not
wash the vehicle in full sun.
● Do not use rough sponges or similar which
could damage the surface to clean away the
traces of insects.
● Never wipe the headlights with a dry cloth
or sponge, always moisten first. It is best to
use soapy water.
● Washing the vehicle in low temperatures:
When washing the vehicle with a hose, do
not direct water into the lock cylinders or the
gaps around the doors or roof. Locks and
seals could freeze! CAUTION
To prevent damage to the vehicle, please ob-
serve the following before entering an auto-
matic car wash: ●
Compare the distance between the vehicle
wheels and the distance between the guide-
rails of the car wash to prevent damage to the
wheels and tyres!
● Switch off the rain sensor before taking the
vehicle to an automatic car wash.
● Compare the height and width of your vehi-
cle with the available height and width when
entering and driving through the car wash.
● Fold in exterior mirrors Electrically retracta-
ble exterior mirrors must not be folded in or
out by hand. Always use the electrical power
control.
● To avoid damaging the bonnet paintwork,
rest the windscreen wipers on the windscreen
after drying the wiper blades. Do not let them
fall!
● Lock the rear lid to prevent it from opening
unexpectedly while inside the car wash. Washing the vehicle with high
pressure cleaning apparatus
When cleaning the vehicle with a high-pres-
sure cleaner, always follow the operating in-
structions for the equipment. Pay special at-
tention to the required pressure of the jet
and the
distance
between the jet and the ve-
hic

le ››› .
Keep a suitable distance from soft materials,
such as rubber hoses or insulating material, »

In natural gas engines
The warning lamp  lights up when both fuel
type

s (petrol and natural gas) have reached
reserve level.
The warning lamp  lights up when the vehi-

e is running in natural gas operating mode.
The warning lamp  switches off when the
natural gas is exhausted. The engine
changes to operate with petrol.
Problem:
if the vehicle is left parked for a
long time just after refuelling, the gas level
indicator does not accurately indicate the
same level shown after refuelling when the
vehicle is started up again. This is not due to
a leak in the system, but to a drop in pres-
sure in the gas tank for technical reasons af- ter a cooling phase immediately after refuel-
ling. WARNING
Driving with insufficient fuel reserve could re-
sult in the vehicle breaking down in traffic
and a serious accident.
● If the fuel level is too low then the fuel sup-
ply to the engine can become irregular espe-
cially on slopes.
● If the engine “is choked” or stalls due to
lack of or irregularity of the fuel supply, the
power steering as well as all of the driver as-
sistance systems including braking assis-
tance will stop working.
● Always refuel when there is only one quar-
ter of the fuel tank left to avoid running out of
fuel. CAUTION
● Always pay attention to any lit control
lamps and to the corresponding descriptions and instructions to avoid damage to the vehi-
cle.
● Never run the fuel tank completely dry. An
irregular fuel supply may lead to ignition
faults and unburnt fuel could enter the ex-
haust system. This could damage the catalyt-
ic converter. Note

Engine coolant Introduction WARNING
Engine coolant is toxic!
● Only keep engine coolant in its original
container, tightly shut and in a safe place.
● Never store engine coolant in empty food
containers or bottles as other people may ac-
cidentally drink it.
● Always keep engine coolant out of reach of
children.
● Ensure that the proportion of engine cool-
ant additive corresponds to the lowest out-
side temperature to which the vehicle will be
exposed.
● If the outside temperature is extremely low,
the engine coolant could freeze causing the
vehicle to stop. As this would also cause the
heating to stop working, vehicle occupants
without warm clothing could freeze. For the sake of the environment
Coolants and additives can contaminate the
environment. Collect any spilt fluids in suita-
ble containers and dispose of them in accord-
ance with legislation and with the utmost re-
spect for the environment. Coolant warning lamp

On the display of the Portable Navigation
System (supplied by SEAT) ››› page 123 an en-
gine coolant temperature gauge can be seen. Engine coolant specifications
The engine cooling system is supplied from
the factory with a specially treated mixture of
water and, at least, 40 % of the additive
G 13
(TLVW 774 J). The engine coolant additive is
recognisable by its purple colour. This mix-
ture of water and additive gives the necessa-
ry frost protection down to -25°C (-13 F) and
protects the light alloy parts of the cooling
system against corrosion. It also prevents
scaling and considerably raises the boiling
point of the coolant.
To protect the engine cooling system, the
percentage of additive must always be at
l e

ast 40 %, even in warm climates where an-
ti-freeze protection is not required.
If greater frost protection is required in very
cold climates, the proportion of additive can
be increased. However, the percentage of ad-
ditive should not exceed 60%, as this would

WARNING
Working on the vehicle battery and the elec-
trical system can cause corrosion, fire and electric shocks. Always read and take into ac-
count the following warnings and safety
standards before carrying out any work:
●
Before working on the battery, switch off
the engine, the ignition and all electrical de-
vices then disconnect the negative connec-
tion on the battery.
● Keep children away from acid and the bat-
tery itself!
● Wear eye protection.
● Battery acid is very corrosive and caustic. It
can burn skin and cause blindness. When
handling the battery, protect yourself from
splashes of acids, above all your hands, arms
and face.
● Do not smoke and never work close to pla-
ces exposed to flames or sparks.
● Avoid sparks and electrostatic discharges
when working with cables and electrical devi-
ces.
● Never short the battery terminals.
● Never use a damaged battery. It can ex-
plode. Replace a damaged battery immedi-
ately.
● Replaced damaged or frozen batteries as
soon as possible. A flat battery can also
freeze at temperatures close to 0 °C (+32 °F). CAUTION
● Never disconnect the battery if the ignition
is switched on or if the engine is running. This could damage the electrical system or
electronic components.
● Do not expose the battery to direct sunlight
over a long period of time, as the intense ul-
traviolet radiation can damage the battery
housing.
● If the car is left standing for long periods,
protect the battery from extreme cold temper-
ature so that it does not “freeze up” and be-
come damaged. Warning lamp

Checking and refilling levels
recommends you have the battery replaced
by a technical service.
Use only maintenance-free genuine batteries
conforming to TL 825 06 and VW 7 50 73
Standards. These standards must be dated
April 2008 or later.
Vehicles fitted with the Start-Stop system are
equipped with a special battery. Therefore,
this battery must only be replaced by another
with the same specifications.
Disconnecting the vehicle's battery
If you must disconnect the battery from the
electrical system, please note the following:
● Switch off the ignition and all electrical
equipment.
● The vehicle must be unlocked before dis-
connecting the battery, otherwise the alarm
will be triggered.
● First disconnect the negative cable and
then the positive ››› .
Connecting the vehicle's battery
● Before reconnecting the battery, switch off
the engine and all electrical devices.
● First reconnect the positive cable and then
the negative ››› .
Different control lamps may light up after
connecting the battery and switching the ig-
nition on. They will be turned off after a short trip at a speed of between 15-20 km/h
(10-12 mph). If the warning indicators remain
lit, please visit a specialised workshop to
have the vehicle checked.
If the battery has been disconnected for a
long time, it is possible that the next service
date is not displayed or calculated correctly

Programme.
Autom

atic device disconnection
The intelligent vehicle electrical system auto-
matically implements a range of measures to
prevent the battery from discharging when
high demands are made on it:
● The idling speed is increased so that the al-
ternator provides more electricity.
● Where necessary, the power to the most
powerful devices is reduced or even com-
pletely disconnected.
● On starting the engine, the power supply
from the 12-volt power sockets and the ciga-
rette lighter may be interrupted for a short
time.
The on-board management program cannot
always prevent the battery from running flat.
For example, if the ignition is left on for a
long period with the engine off or if the side
lights or parking lights are left on while the
vehicle is stationary. Why the battery runs flat:
●
When stationary for a long time without
starting the engine, particularly if the ignition
is switched on.
● Use of electrical devices with the engine
switched off. WARNING
Incorrectly securing the battery or using the
wrong battery can cause short-circuits, fire
and serious injuries.
● Always use only maintenance-free batter-
ies, protected to prevent a leak, and whose
properties, specifications and size corre-
spond to the standard battery. WARNING
A highly explosive mixture of gases is re-
leased when the battery is under charge.
● The batteries should be charged in a well-
ventilated room only.
● Never charge a frozen or recently thawed
battery. A flat battery can also freeze at tem-
peratures close to 0 °C (+32 °F).
● Always replace a battery which has frozen.
● Battery cables not correctly connected may
cause a short circuit. Reconnect first the posi-
tive cable and then the negative cable. » 157

Advice
Foreign bodies in the tyre
● Do not remove foreign bodies if they have
penetrated through the tyre wall!
● You should obtain professional assistance
immediately.
Wear of tyres
The wear of tyres depends on a number of
factors, for example:
● Driving style.
● Unbalanced wheels.
● Running gear settings.
Driving style : Driving round bends quickly or
sudden acceleration or braking speed accel-
erates tyre wear. When the driving style is
normal, if the tyres wear too quickly, have the
running gear settings checked at a special-
ised workshop.
Wheel run-out : The wheels on new vehicles
ar e b
alanced. However, certain circumstan-
ces may lead to imbalance (run-out), which is
detected as vibrations in the steering wheel.
Run-out leads to wear of the steering and
suspension. In the event of run out, the
wheels should be balanced again. When a
new wheel is fitted, it should be balanced
again.
Running gear settings : an incorrectly posi-
tioned running gear increases the wear of
tyres and affects your safety while driving. If tyres wear too quickly, have the wheel align-
ment checked at a specialised workshop. WARNING
If you notice unusual vibration or the car pulls
to one side while driving, this may indicate
that one of the tyres is damaged.
● Reduce speed immediately and stop, while
observing the highway code.
● Check the wheels and tyres for damage.
● Never carry on driving on worn tyres or
wheels. Request qualified assistance immedi-
ately.
● If there is no visible exterior damage, drive
slowly and carefully to the nearest special-
ised workshop and have the vehicle checked. Tyre monitoring system* 
Fig. 117
Centre console: tyre monitor system
button The tyre control lamp compares wheel revolu-
tions and with it, the wheel diameter of each
wheel using the ESC. If the diameter of a
wheel changes, the tyre control lamp

lights up. The wheel diameter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a
load.
● The wheels of one axle are under more
pressure (for example, driving with a trailer or
on steep slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed.
Tyre pressure adjustment
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 117 button must
be k ept
pressed down, with the ignition on,
until an acoustic signal is heard.
If the wheels are under excessive load (for ex-
ample, driving with a trailer or heavy load),
the tyre pressure must be increased to the
recommended value for a full load (see the
sticker on the inside of the fuel flap). If the
tyre monitor system button is pressed down,
the new tyre pressures are confirmed.

Wheels and tyres
The tyre pressure control lamp  lights up
If the ty
re pressure of a wheel is much lower
than the value set by the driver, then the tyre
pressure control lamp ››› will light up.
WARNING
● When the tyre pressure control lamp lights
up, reduce speed immediately and avoid any
sudden turning or braking manoeuvre. Stop
when possible, and check the tyre pressure
and status.
● The driver is responsible for maintaining
correct tyre pressures. For this reason, tyre
pressure must be regularly checked.
● Under certain circumstances (e.g. when
driving in a sporty manner, in winter condi-
tions or on a dirt track) the tyre control lamp
may light up belatedly or may function incor-
rectly. Note
If the battery is disconnected, the yellow
warning lamp  lights up after turning the
ignition on.

This should turn off after a brief
journey. Spare wheel or temporary spare

cides with the opening.
● Turn the hand controlled wheel with the
shank screwed clockwise until the replaced
wheel is secured.
● If necessary, store the vehicle tool in the
container, inside the boot.
● Replace the carpet on the boot floor.
● Lower the rear shelf.
● Close the rear lid.
If the spare wheel is different to the rest of
the vehicle tyres
If the spare tyre is not the same as the tyres
that are mounted on the vehicle - for example
with winter tyres or the temporary spare
wheel - you should only use the spare tyre for
a short period of time and drive with extra
care ››› .
Refit the normal road wheel as soon as possi-
ble.
Please observe driving advice:
● Do not drive faster than 80 km/h (50 mph).
● Avoid heavy acceleration, hard braking and
fast cornering. »
