seek medical care immediately. Neutralise
any
ac
id splashes on the skin or clothing
with a soapy solution, and rinse off with plen-
ty of water. If acid is swallowed by mistake,
consult a doctor immediately.
● Fires, sparks, open flames and smoking are
prohibit
ed. When handling cables and electri-
cal equipment, avoid causing sparks and
electrostatic charge. Never short the battery
terminals. High-energy sparks can cause in-
jury.
● A highly explosive mixture of gases is re-
lea
sed when the battery is under charge. The
batteries should be charged in a well-ventila-
ted room only.
● Keep children away from acid and batteries.
● Before working on the electrical system,
you mus
t switch off the engine, the ignition
and all electrical devices. The negative cable
on the battery must be disconnected. When a
light bulb is changed, you need only switch
off the light.
● Deactivate the anti-theft alarm by unlock-
ing the v
ehicle before you disconnect the bat-
tery! The alarm will otherwise be triggered.
● When disconnecting the battery from the
vehicl
e on-board network, disconnect first
the negative cable and then the positive ca-
ble.
● Switch off all electrical devices before re-
connecting the b
attery. Reconnect first the
positive cable and then the negative cable.
Never reverse the polarity of the connections.
This could cause an electrical fire. ●
Never c h

arge a frozen battery, or one which
has thawed. This could result in explosions
and chemical burns. Always replace a battery
which has frozen. A flat battery can also
freeze at temperatures close to 0°C (+32°F).
● Ensure that the vent hose is always connec-
ted to the b
attery.
● Never use a defective battery. This could
cause an e
xplosion. Replace a damaged bat-
tery immediately. CAUTION
● Nev er di s

connect 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 lon
g period of time, as the intense ul-
traviolet radiation can damage the battery
housing.
● If the vehicle is left standing in cold condi-
tions f
or a long period, protect the battery
from “freezing”. If it freezes it will be dam-
aged. Warning lamp

The “magic eye” indicator, located on the top
of the battery changes colour, depending on
the charge state and electrolyte level of the
battery.
There are two different colours:
● Black: correct charge status.
● Transparent/clear yellow: the battery must
be repl

Charging or changing the battery The battery is maintenance-free and is
c
hec
k

ed during the inspection service. All
work on the vehicle battery requires special-
ist knowledge.
If you often drive short distances or if the ve-
hicle is not driven for long periods, the bat-
tery should be checked by a specialised
workshop between the scheduled services.
If the battery has discharged and you have
problems starting the vehicle, the battery
might be damaged. If this happens, we rec-
ommend you have the vehicle battery
checked by a Technical Service where it will
be re-charged or replaced. Charging the battery
The vehic

le battery should be charged by a
specialised workshop only, as batteries us-
ing special technology have been installed
and they must be charged in a controlled en-
vironment.
Replacing a vehicle battery
The battery has been developed to suit the
conditions of its location and has special
safety features.
Genuine SEAT batteries meet the mainte-
nance, performance and safety specifications
of your vehicle. WARNING
● We r ec

ommend you use only maintenance-
free or cycle free leak-proof batteries which
comply with standards T 825 06 and
VW 7 50 73. This standard applies as of
2001.
● Before starting any work on the batteries,
you mus
t read and observe the warnings
››› in Symbols and warnings on handling
the batt er

y on page 281. For the sake of the environment
Batteries contain toxic substances such as
su lphuric

acid and lead. They must be dis-
posed of appropriately and must not be dis-
posed of with ordinary household waste. Wheels

General notes Avoiding damage
– If you have to drive over a kerb or similar
ob s

tacle, drive very slowly and at a right
angle.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage
(cuts, c r

acks or blisters, etc.). Remove any
foreign objects embedded in the treads.
Storing tyres
– When you remove the tyres, mark them in
order to m

aintain the same direction of ro-
tation when they are installed again.
– When removed, the wheels and/or tyres
should be s

tored in a cool, dry and prefera-
bly dark location.
– Store tyres in a vertical position, if they are
not fitted on wheel

rims.

Concealed damage
Dam ag
e t
o tyres and rims is often not readily
visible. If you notice unusual vibrations or the
vehicle pulling to one side, this may indicate
that one of the tyres is damaged. They
should be checked immediately by a Techni-
cal Service.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on tyres with directional
tread. Always observe the direction of rota-
tion indicated when fitting the wheel. This
guarantees optimum grip and helps to avoid
aquaplaning, excessive noise and wear. WARNING
● New tyr e

s do not have maximum grip dur-
ing the first 500 km. Drive particularly care-
fully to avoid possible accidents.
● Never drive with damaged tyres. This may
cause an ac
cident.
● If you notice unusual vibrations or if the ve-
hicle p
ulls to one side when driving, stop the
vehicle immediately and check the tyres for
damage. Tyre pressure monitoring system
Fig. 239
Location of the tyre pressure sticker. The maximum tyre pressure values are shown
on a s
tic
k

er stuck to the back of the left front
door frame ›››
Fig. 239.
1. Read the required tyre inflation pressure from the stic
ker. The values refer to Sum-
mer tyres.
2. The tyre pressures should only be checked when the tyre
s are cold. The slightly raised
pressures of warm tyres must not be re-
duced.
3. Adjust the tyre pressure to the load you are carr
ying. Tyre pressure
The correct

tyre pressure is especially impor-
tant at high speeds. The pressure should
therefore be checked at least once a month
and before starting a journey.
Depending on the vehicle, tyre pressure can
be adjusted to medium load to improve driv-
ing comfort (“comfort” tyre pressure). When
driving with comfort tyre pressure fuel con-
sumption may increase slightly. WARNING
A tyre can easily burst if the pressure is too
low , c

ausing an accident!
● 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 tyre
s 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. 284

Wheels
Service life of tyres Fig. 240
Tyre tread wear indicators. Fig. 241
Diagram for changing wheels. The useful life of tyres is dependent on tyre
pr
e
s
sure, driving style and fitting.
Wear indicators
The original tyres on your vehicle have
1.6 mm high “tread wear indicators”
››› Fig. 240, running across the tread. De- pending on the make, there will be 6 to 8 of
them evenly

spaced around the tyre. Mark-
ings on the tyre sidewall (for instance the let-
ters “TWI” or other symbols) indicate the po-
sitions of the tread wear indicators. The mini-
mum tread depth required by law is 1.6 mm
(measured in the tread grooves next to the
tread wear indicators). Worn tyres must be re-
placed. Different figures may apply in export
countries ››› .
T y
r

e pressure
Incorrect tyre pressure causes premature
wear and could cause tyre blow-out. For this
reason, the tyre pressure should be checked
at least once per month ››› page 284.
Driving style
Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more
than the rear ones it is advisable to change
them around as shown ››› Fig. 241. The use-
ful life of all the tyres will then be about the
same time.
Wheel balance
The wheels on new vehicles are balanced.
However, various factors encountered in nor-
mal driving can cause them to become unbal-
anced, which results in steering vibration. Unbalanced wheels should be rebalanced, as
they otherw

ise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted.
Incorrect wheel alignment
Incorrect running gear alignment causes ex-
cessive tyre wear, impairing the safety of the
vehicle. If tyres show excessive wear, you
should have the wheel alignment checked by
a Technical Service. WARNING
There is a serious danger of accidents if a tyre
bur s

ts during driving!
● The tyres must be replaced at the latest
when the trea
d wear indicators are worn
››› page 285. Failure to follow this instruction
could result in an accident. Worn tyres do not
grip well at high speeds on wet roads. There
is also a greater risk of “aquaplaning”.
● At continuously high speeds, a tyre with in-
sufficient
pressure flexes more. This causes it
to overheat. This can cause tread separation
and tyre blow-out. Risk of accident. Always
observe the recommended tyre pressures.
● If tyres show excessive wear, you should
have the ru
nning gear checked by a Technical
Service.
● Keep chemicals such as oil, fuel and brake
fluid awa
y from tyres.
● Damaged wheels and tyres must be re-
plac
ed immediately! » 285

Wheels
Wheel bolts The design of wheel bolts is matched to the
rims. If diff
er
ent wheel rims are fitted, the
correct wheel bolts with the right length and
correctly shaped bolt heads must be used.
This ensures that wheels are fitted securely
and that the brake system functions correctly.
In certain circumstances, you should not use
wheel bolts from a different vehicle, even if it
is the same model ››› page 259. WARNING
If the wheel bolts are not tightened correctly,
the wheel c ou

ld become loose while driving.
Risk of accident.
● The wheel bolts must be clean and turn
eas
ily. Never apply grease or oil to them.
● Use only wheel bolts which belong to the
wheel.
● If the pr

escribed torque of the wheel bolts
is t
oo low, they could loosen whilst the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged. CAUTION
The prescribed tightening torque for wheel
bolt s

for steel and alloy wheels is 120 Nm. Tyre monitoring indicator*

● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a

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 back of the left front door
frame). If the tyre monitor system button is
pressed down, the new tyre pressures are
confirmed.

WARNING
● When the tyr e pr

essure 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. » 287

W int
er ty

res In winter conditions winter tyres will consid-
er
ab
ly

improve the vehicle's handling. The
design of summer tyres (width, rubber com-
pound, tread pattern) gives less grip on ice
and snow.
Winter tyres must be inflated to a pressure of
0.2 bar (2.9 psi/20 kPa) higher than the pres-
sures specified for summer tyres (see the
sticker on the back of the left front door
frame).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes
can be found in the vehicle's registration
documentation. Use only radial winter tyres. All tyre sizes listed in the vehicle documenta-
tion also app

ly to winter tyres.
Winter tyres lose their effectiveness when the
tread is worn down to a depth of 4 mm.
The speed rating code ››› page 286, New
tyres and wheels determines the following
speed limits for winter tyres: ››› max. 160 km/h (99 mph)
m
ax. 180 km/h (112 mph)
m ax. 190 km/h (118 mph)
m

ax. 210 km/h (130 mph)
In some countries, vehicles which can exceed
the speed rating of the fitted tyre must have
an appropriate sticker in the driver's field of
view. These stickers are available from your
technical service. The legal requirements of
each country must be followed.
Do not have winter tyres fitted for unnecessa-
rily long periods. Vehicles with summer tyres
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 286, New
tyres and wheels . WARNING
The maximum speed for the winter tyres must
not be e x

ceeded. Otherwise, this could lead
to damage and risk of accident. » Q

Drawbar loads
The maximum permitt ed dr
a
wbar load on the
ball coupling of the towing bracket must not
exceed 55 kg.
In the interest of road safety, we recommend
that you always tow approaching the maxi-
mum drawbar load. The response of the trail-
er on the road will be poor, if the drawbar
load is too small.
If the maximum permissible drawbar load
cannot be met (e.g. with small, empty and
light-weight single axle trailers or tandem
axle trailers with a wheelbase of less than 1
metre), a minimum of 4% of the actual trailer
weight is legally required for the drawbar
load. WARNING
● For s af

ety reasons, you should not drive at
speeds above 80 km/h (50 mph) when towing
a trailer. This also applies in countries where
higher speeds are permitted.
● Never exceed the maximum trailer weights
or the drawb
ar load. If the permissible axle
load or the permissible total weight is excee-
ded, the driving characteristics of the vehicle
may change, leading to accidents, injuries
and damage to the vehicle. Wheels

are for cold tyres. Do not reduce the slightly
raised pressures of warm tyres ››› .
The pre s

than that of summer tyres (2.9 psi / 20 kPa).
Wheel bolts
After the wheels have been changed, the
tightening torque of the wheel bolts should
be checked as soon as possible with a torque
wrench ››› . The tightening torque for steel
and al lo
y

wheels is 120 Nm. WARNING
● Check the ty

re pressure at least once per
month. Checking the tyre pressure is very im-
portant. If the tyre pressure is too high or too
low, there is an increased danger of accidents
- particularly at high speeds.
● If the tightening torque of the wheel bolts
is t
oo low, they could loosen while the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
