ma y
stall in traffic, or may cause accidents
and severe injuries.
● Never ignore the warning lamps.
● Stop the vehicle safely as soon as possible.
● Park the vehicle away from traffic and en-
sure th
at there are no highly flammable ma-
terials under the vehicle that could come into
contact with the exhaust system (e.g. dry
grass, fuel).
● A faulty vehicle represents a risk of acci-
dent for the driv
er and for other road users. If
necessary, switch on the hazard warning
lamps and put out the warning triangle to ad-
vise other drivers.
● Before opening the bonnet, switch off the
engine and al

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 G13
(TL-VW 774 J), purple. This mixture gives the
necessary frost protection down to -25 °C
(-13 °F) and protects the light alloy parts of
the engine cooling system against corrosion.
It also prevents scaling and considerably rai-
ses the boiling point of the coolant.
To protect the cooling system, the percentage
of additive must always be at least 40 %, even in warm climates where anti-freeze pro-
tection is

not required.
If for weather reasons further protection is
necessary, the proportion of additive may be
increased, but only up to 60 %; otherwise an-
tifreeze protection will diminish and this will
worsen cooling.
When the coolant is topped up, use a mixture
of distilled water and at least 40 % of the
G13 or G12 plus-plus (TL-VW 774 G) additive
(both are purple) to obtain an optimum anti-
corrosion protection ››› in Checking the
c oo
l

ant level and topping up on page 191.
The mixture of G13 with G12 plus (TL-VW 774
F), G12 (red) or G11 (green-blue) engine cool-
ants will significantly reduce anti-corrosion
protection and should therefore be avoided

WARNING
If the vehicle is not correctly raised, it could
fa l
l off the jack causing serious injury. Please
observe the following rules to minimise the
risk of injury:
● You should only use a jack approved by
SEAT f
or your vehicle. Other jacks, even those
approved for other SEAT models, might slip
out of place.
● The ground should be firm and flat. If the
ground i
s sloped or soft then the vehicle
could slip and fall off the jack. If necessary,
support the jack on a wide solid base.
● If the ground is slippery, such as tiles,
plac
e a non-slip surface (a floor mat, for in-
stance) beneath the jack to avoid slipping.
● Only fit the jack at the prescribed jacking
points. The c
law of the jack should grip the
reinforcement nerve on the underbody
››› Fig. 56.
● You should never place a body limb such as
an arm or leg u
nder a raised vehicle that is
solely supported by the jack.
● If you have to work underneath the vehicle,
you mus
t use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!.
● Never raise the vehicle if it is tilting to one
side or the engine i
s running.
● Never start the engine when the vehicle is
raised.
The vehicle may come loose from the
jack due to the engine vibrations. Removing and fitting a wheel

Removing the wheel
● Slacken the wheel bolts ›››
page 37.
● Raise the vehicle ›››
page 38.
● Using the hexagonal socket in the wheel
brace ›

›› Fig. 57, unscrew the slackened
wheel bolts and place them on a clean sur-
face.
● Take off the wheel.
How to u
se the spare wheel or temporary
spare wheel
Check the direction of rotation of the tyre
›››  page 205, Tyre code. ●
Place the s
pare wheel or temporary spare
wheel into position.
● Replace the wheel bolts and tighten slight
-
ly using the hexagonal socket on the end of
the wheel brace.
● To tighten the anti-theft locking wheel bolts
use the corr
esponding adaptor.
● Lower the car with the jack.
● Tighten all of the wheel bolts clockwise
›››
. Tighten the bolts in diagonal pairs (not
in a c ir
c
le).
● Put the caps, trim or full hubcap back on
›››
page 36. WARNING
If the wheel bolts are not treated suitably or
not tight ened t

o the correct torque then this
could lead to loss of vehicle control and to a
serious accident.
● All the wheel bolts and hub threads should
be cle
an and free of oil and grease. The wheel
bolts should be easily tightened to the cor-
rect torque.
● The hexagonal socket in the wheel brace
should be u
sed for turning wheel bolts only.
Do not use it to loosen or tighten the wheel
bolts. 39
