For the sake of the environment
Service fluids leaks are harmful to the envi-
ronment. For this reason you should make
regular checks on the ground underneath
your vehicle. If you find spots of oil or other
fluids, have your vehicle inspected in a speci-
alised workshop. Opening the bonnet

Handle for releasing the bonnet. The bonnet is released from inside the vehi-
cle.
Before opening the bonnet ensure that the
windscreen wipers are in rest position.
– To release the bonnet, pull the lever under
the dash panel ››› Fig. 144 in the direction
indic at
ed (arrow). The bonnet will be re-
leased by a spring action ››› .
– Lift the bonnet using the release lever (ar-
row) and open the bonnet.
– Release the bonnet stay and secure it in
the fixture designed for this in the bonnet. WARNING
Hot coolant can scald!
● Never open the bonnet if you see steam,
smoke or coolant escaping from the engine
compartment. ●
Wait until no more steam, smoke or coolant
is emitted from the bonnet, then carefully
open the bonnet.
● When working in the engine compartment,
always observe the safety warnings
››› page 163. Closing the bonnet
–
Slightly lift the bonnet.
– Release the bonnet stay and replace it in its
support.
– At a height of approximately 30 cm let it fall
so it locks.
If the bonnet does not close, do not press
downwards. Open it once more and let it fall
as before. WARNING
If the bonnet is not closed properly, it could
open while you are driving and completely
obscure your view of the road. Risk of acci-
dent.
● After closing the bonnet, always check that
it is properly secured. The bonnet must be
flush with the surrounding body panels.
● If you notice that the bonnet latch is not se-
cured when the vehicle is moving, stop the
vehicle immediately and close the bonnet
properly. Risk of accident. 165

WARNING
Any work carried out in the engine compart-
ment or on the engine must be carried out
cautiously.
● When working in the engine compartment,
always observe the safety warnings
››› page 163.
● When the engine is warm or hot, the cool-
ing system is pressurised! Do not unscrew
the cap on the coolant expansion tank when
the engine is hot. This is a burn injury risk. CAUTION
● When mixed with other additives the colour
of G12 will change to brown. If this occurs
you should have the coolant changed imme-
diately. Failure to do so will result in engine
damage!
● If a lot of coolant fluid has been lost, wait
for the engine to cool. This avoids damaging
the en gine. Lar
ge coolant losses are an indi-
cation of leaks in the cooling system. See a
specialised workshop immediately and have
the cooling system checked. Otherwise, there
is a risk of engine damage. Windscreen washer reservoir
Topping up washer fluid  Fig. 150
In the engine compartment: Cap of
windscreen washer fluid reservoir The
windscreen washer
and the
headlight
washers are supplied with fluid from the
windscreen washer fluid container in the en-
gine compartment. The container holds ap-
prox. 3 litres; in vehicles with headlight
washers* it holds approx. 5.5 litres.
The reservoir is located on the right-hand
side of the engine compartment.
Plain water is not enough to clean the wind-
screen and headlights. We recommend that
you always add a product to the windscreen
washer fluid. Approved windscreen cleaning
products exist on the market with high deter-
gent and anti-freeze properties, these may be
added all-year-round. Please follow the dilu-
tion instructions on the packaging. WARNING
Any work carried out in the engine compart-
ment or on the engine must be carried out
cautiously.
● When working in the engine compartment,
always observe the safety warnings
››› page 163. CAUTION
● Never put radiator anti-freeze or other addi-
tives into the windscreen washer fluid.
● Always use approved windscreen cleansing
products diluted as per instructions. If you
use other washer fluids or soap solutions,
the tiny holes in the fan-shaped nozzles
could become blocked. 171

Brake fluid Checking the brake fluid level Fig. 151
Engine compartment: brake fluid
reservoir cap –
Read off the fluid level at the transparent
brake fluid reservoir. It should always be
between the “MIN” and “MAX” marks.
The position of the brake fluid reservoir is
shown in the corresponding engine compart-
ment illustration ››› page 166. The brake fluid
reservoir has a black and yellow cap.
The brake fluid level drops slightly when the
vehicle is being used as the brake pads are
automatically adjusted as they wear.
However, if the level goes down noticeably in
a short time, or drops below the “MIN” mark,
there may be a leak in the brake system. A
display on the instrument panel will warn you
if the brake fluid level is too low ››› page 35. WARNING
Before opening the bonnet to check the brake
fluid level, read and observe the warnings
››› page 163. Changing the brake fluid
The Maintenance Programme indicates brake
fluid change intervals.
We recommend that you have the brake fluid
changed by a Technical Service.
Before opening the bonnet, please read and
follow the warnings
››› in Safety instruc-
tions on working in the engine compartment
on page 163 in section “Safety notes for
w ork
ing in the engine compartment”.
In the course of time, brake fluid becomes
hygroscopic and absorbs water from the am-
bient air. If the water content in the brake flu-
id is too high, the brake system could cor-
rode. This also considerably reduces the boil-
ing point of the brake fluid. Heavy use of the
brakes may then cause a vapour lock which
could impair the braking effect.
Be sure to always use the correct brake fluid.
Only use brake fluid that expressly meets the
VW 501 14 standard.
You can buy VW 501 14 standard brake fluid
at a SEAT dealership or a SEAT Official Serv-
ice. If none is available, use only high-quality brake fluid that meets DIN ISO 4925 CLASS 4
standards, or USA Standards FMVSS 116 DOT
4.
Using any other kind of brake fluid or one
that is not of a high quality may affect opera-
tion of the brake system and reduce its effec-
tiveness. Never use a brake fluid if the con-
tainer does not state that it complies with VW
501 14, DIN ISO 4925 CLASS 4 standards, or
USA standards FMVSS 116 DOT 4.
WARNING
Brake fluid is poisonous. Old brake fluid im-
pairs the braking effect.
● Before opening the bonnet to check the
brake fluid level, read and observe the warn-
ings ››› page 163.
● Br ak
e fluid should be stored in the closed
original container in a safe place out of reach
of children. There is a toxic risk.
● Perform the brake fluid change according to
the Maintenance Programme. Heavy use of
the brakes may cause a vapour lock if the
brake fluid is left in the brake system for too
long. This would seriously affect the effec-
tiveness of the brakes and the safety of the
vehicle. This may cause an accident. CAUTION
Brake fluid damages the vehicle paintwork.
Wipe off any brake fluid from the paintwork
immediately. 172

Checking and refilling levels
For the sake of the environment
The brake pads and brake fluid must be col-
lected and disposed of according the applica-
ble regulations. The SEAT Technical Service
network has the necessary equipment and
qualified personnel for collecting and dispos-
ing of this waste material. Vehicle battery
Warnings on handling the battery Wear eye protection

Battery acid is extremely corrosive. Wear pro-
tective gloves and eye protection!

Fires, sparks, open flames and smoking are
prohibited!

A highly explosive mixture of gases is released
when the battery is under charge.

Keep children away from acid and batteries!
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 con-
taining lead. ●
Battery acid is extremely corrosive. Wear
protective gloves and eye protection. Do not
tilt the batteries. This could spill acid through
the vents. Rinse battery acid from eyes imme-
diately for several minutes with clear water.
Then seek medical care immediately. Neutral-
ise any acid 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
prohibited. 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-
leased 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 must 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 vehicle before you disconnect the bat-
tery! The alarm will otherwise be triggered.
● When disconnecting the battery from the
vehicle on-board network, disconnect first
the negative cable and then the positive ca-
ble. ●
Switch off all electrical devices before re-
connecting the battery. Reconnect first the
positive cable and then the negative cable.
Never reverse the polarity of the connections.
This could cause an electrical fire.
● Never charge 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 battery.
● Never use a defective battery. This could
cause an explosion. Replace a damaged bat-
tery immediately. 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 vehicle is left standing in cold condi-
tions for a long period, protect the battery
from “freezing”. If it freezes it will be dam-
aged. 173

result in an explosion.
● Never use jump leads when one of the bat-
teries is frozen. Danger of explosion! Even 190

Advice
Driving style
Towing requires some experience, especially
when using a tow rope. Both drivers should
be familiar with the technique required for
towing. Inexperienced drivers should not at-
tempt to tow.
Do not pull too hard with the towing vehicle
and take care to avoid jerking the tow rope.
When towing on an unpaved road, there is al-
ways a risk of overloading and damaging the
anchorage points.
The ignition of the vehicle being towed must
be switched on to prevent the steering wheel
from locking and also to allow the use of the
turn signals, horn, windscreen wipers and
washers.
The brake servo only works when the engine
is running. When not running, you must ap-
ply considerably more pressure to the brake
pedal.
As the power assisted steering does not work
if the engine is not running, you will need
more strength to steer than you normally
would.
● The vehicle must not be towed faster than
50 km/h (31 mph).
Towing vehicles with an automatic gearbox
● Put the selector lever into position “N”.
● Do not drive faster than 50 km/h (31 mph). ●
Do not tow further than 50 km.
● If a breakdown vehicle is used, the vehicle
must be towed with the front wheels raised. Note
● Observe legal requirements when towing or
tow-starting.
● Switch on the hazard warning lights of both
vehicles. However, observe any regulations
to the contrary.
● For technical reasons, vehicles with an au-
tomatic gearbox must not be tow-started.
● If there is no lubricant in the gearbox as the
result of a fault, you must raise the driven
wheels while the vehicle is being towed.
● If the vehicle has to be towed more than
50 km, the front wheels should be raised dur-
ing towing, and towing should be carried out
by a qualified person.
● The steering wheel is locked when the vehi-
cle has no electrical power. The vehicle must
then be towed with the front wheels raised.
Towing should be carried out by a qualified
person.
● The towline anchorage should always be
kept in the vehicle. Please refer to the notes
on ››› page 191, Tow-starting. Towline anchorages
