•
Before opening the bonnet to check the brake fluid level, read and
observe the warnings ⇒page 193.
•
Brake fluid should be stored in the closed original container in a safe
place out of reach of children. This represents a toxic danger.
•
Have the brake fluid changed every two years at the latest. Heavy use
of the brakes may cause a vapour lock if the brake fluid is left in the system
for too long. This would seriously affect the efficiency of the brakes and the
safety of the vehicle. This may be an accident risk.Caution
Brake fluid could damage the paintwork. Wipe off any brake fluid from the
paintwork immediately.
For the sake of the environment
Brake fluid must be drained and disposed of in the proper manner observing
environmental regulations.
BatteryWarnings on handling the battery
WARNING
Always be aware of the danger of injury and chemical burns as well as the
risk of accident or fire when working on the battery and the electrical
system:•
Wear eye protection. Protect your eyes , skin and clothing from acid and
particles containing lead.
•
Battery acid is very corrosive and caustic. Wear protective gloves and
eye protection. Do not tilt the batter ies. This could spill acid through the
vents. Rinse battery acid from eyes immediately for several minutes with
clear water. Then seek medical care immediately. Neutralize any acid
splashes on the skin or clothing with a soapy solution, and rinse off with
plenty of water. If acid is swallowed by mistake, consult a doctor immedi-
ately.
•
Fires, sparks, naked lights and smoki ng are prohibited. When handling
cables and electrical equipment, avoid causing sparks and electrostatic
WARNING (continued)

WARNING
There is a serious danger of accidents if a tyre bursts during driving!•
The tyres must be replaced at the latest when the tread is worn down to
the tread wear indicators. Failure to do so 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 insufficient 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 pres-
sures.
•
If tyres show excessive wear, you should have the running gear checked
by an Authorised Service Centre.
•
Keep chemicals such as oil, fuel and brake fluid away from tyres.
•
Damaged wheels and tyres must be replaced immediately!For the sake of the environment
Under-inflated tyres will increase fuel consumption.New tyres and wheels
New tyres and wheels have to be run-in.The tyres and wheel rims are an essenti al part of the vehicle's design. The
tyres and rims approved by SEAT are specially matched to the characteristics
of the vehicle and make a major contribution to good road holding and safe
handling ⇒.
Tyres should be replaced at least in pairs and not individually (i.e. both front
tyres or both rear tyres together). A kn owledge of tyre designations makes it easier to choose the correct tyres. Radial tyres have the tyre designations
marked on the sidewall, for example:
195/65 R15 91T
This contains the following information:
195 Tyre width in mm
65 Height/width ratio in %
R Tyre construction: Radial
15 Rim diameter in inches
91 Load rating code
T Speed rating
The tyres could also have the following information:
•
A direction of rotation symbol
•
“Reinforced” denotes heavy-duty tyres.
The manufacturing date is also indicate d on the tyre sidewall (possibly only
on the inner side of the wheel).
“DOT ... 1103 ...” means, for example, that the tyre was produced in the 11th
week of 2003.
We recommend that work on tyres and wheels is carried out by an Authorised
Service Centre. They are familiar with the procedure and have the necessary
special tools and spare parts as well as the proper facilities for disposing of
the old tyres.
Any Authorised Service Centre has full information on the technical require-
ments when installing or changing tyres, wheels or wheel trims.
WARNING
•
We recommend that you use only wheels and tyres which have been
approved by SEAT for your model. Failure to do so could impair vehicle
handling. Risk of accident.

Tips and Maintenance
Te c h n i c a l D a t a
•
Avoid running the vehicle on tyres th at are more than six years old. If
you have no alternative, you should drive slowly and with extra care at all
times.
•
Never use old tyres or those with an unknown “history of use”.
•
If wheel trims are retrofitted, you must ensure that the flow of air to the
brakes is not restricted. This could cause them to overheat.
•
All four wheels must be fitted with radial tyres of the same type, size
(rolling circumference) and the same tread pattern.For the sake of the environment
Old tyres must be disposed of according to the laws in the country concerned.
Note
•
For technical reasons, it is not generally possible to use the wheels from
other vehicles. This can also apply to wheels of the same model. The use of
wheels or tyres which have not been approved by SEAT for use with your
model may invalidate the vehicle's type approval for use on public roads.
•
If the spare tyre is not the same as the tyres that are mounted on the
vehicle - for example with winter tyres - 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 possible.
Wheel bolts
Wheel bolts must be tightened to the correct torque.The design of wheel bolts is matched to the rims. If different 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 may not use wheel bolts from a different car -
even if it is the same model
⇒page 186.
WARNING
If the wheel bolts are not tightened correctly, the wheel could become
loose while driving. Risk of accident.•
The wheel bolts must be clean and turn easily. Never apply grease or oil
to them.
•
Use only wheel bolts which belong to the wheel.
•
If the prescribed torque of the wheel bolts is too low, they could loosen
whilst the vehicle is in motion. Risk of accident! If the tightening torque is
too high, the wheel bolts and threads could be damaged.Caution
The prescribed torque for wheel bolts for steel and alloy wheels is 120 Nm.Winter tyres
Winter tyres will improve the vehicles handling on snow and
ice.In winter conditions winter tyres will considerably improve the vehicles
handling. The design of summer tyre s (width, rubber compound, tread
pattern) gives less grip on ice and snow.
Winter tyres must be inflated to a pressure 0.2 bar higher than the pressures
specified for summer tyres (see sticker on tank flap).
Winter tyres must be fitted on all four wheels.

WARNING
•
Please note the safety warnings referring to working in the engine
compartment ⇒page 193, “Working in the engine compartment”.
•
The battery providing assistance must have the same voltage as the flat
battery (12V) and approximately the same capacity (see imprint on
battery). Failure to comply could result in an explosion.
•
Never use jump leads when one of the batteries is frozen. Danger of
explosion! Even after the battery has thawed, battery acid could leak and
cause chemical burns. If a battery freezes, it should be replaced.
•
Keep sparks, flames and lighted cigarettes away from batteries, danger
of explosion. Failure to comply could result in an explosion.
•
Observe the instructions provided by the manufacturer of the jump
leads.
•
Do not connect the negative cable from the other vehicle directly to the
negative terminal of the flat battery. The gas emitted from the battery could
be ignited by sparks. Danger of explosion.
•
Do not attach the negative cable from the other vehicle to parts of the
fuel system or to the brake line.
•
The non-insulated parts of the battery clamps must not be allowed to
touch. The jump lead atta ched to the positive battery terminal must not
touch metal parts of the vehicle, this can cause a short circuit.
•
Position the leads in such a way that they cannot come into contact
with any moving parts in the engine compartment.
•
Do not bend over the batteries. This could result in chemical burns.Note
The vehicles must not touch each other, otherwise electricity could flow as
soon as the positive terminals are connected.
