– Align jack and at same time wind claw

up further until it contacts the vertical
rib on side member.

It is imperative that the designated direc-
tion  of rotation  for  the  tyre  treads (which
can be determined from the arrow on the
side  of the  tyre)  be  kept to. The  best tyre
performance  i.e.  in  aquaplaning,  road
adhesion,  noise  and  wear  are  then  guar-
anteed.

If a  spare  wheel has to  be  fitted  against
the  stipulated  direction  of rotation,  this
measure should only be a temporary one.
The  best possible  tyre  performance  con-
cerning  aquaplaning,  noise  level and
wear are no longer fully guaranteed.

We  recommend  that you  take  this into
account,  especially in  wet weather,  and
adjust your  speed  to  the  driving  condi-
tions.

In order to use the principle of the direc-
tion of rotation fully again, the faulty tyre
must be replaced as soon as possible.

If necessary, mount the tyre fitted against
the direction of rotation in the stipulated
direction.

•

Place the wheel spanner (from the on

board tools) as far as possible over
adapter 2

2 and loosen or tighten the wheel

bolt.

•

After the wheel has been changed the

adapter needs to be removed from the
wheel bolt.

We recommend that you carry the adapter
for the wheel bolts in the vehicle and stow
it at a location well known to the owner,
preferably with the on board tools.

The code for the wheel bolt is engraved in
the front of the adapter.

If the newly inserted fuse blows again

after a short time, the electrical system
must be checked by a Technical Service

The fuses are located on the left hand
side of the dash panel behind a cover.

On right-hand drive versions, the fuses
are on the right hand side of the dash
panel behind a cover.

•

Switch off the ignition and the compo-

nent concerned.

•

Take the cover off.

To do this, place the flat blade of the
screwdriver in the recess on the cover
(arrow) and lever off.

•

With the aid of the list of fuses (see next

pages or the cover of the fuse box) deter-
mine which fuse belongs to the compo-
nent that has failed.

•

Remove the appropriate fuse.

•

Replace blown fuse – can be recog-

nised by the burnt metal strip – with a
fuse of s

amperage.

•

Replace the cover.

Before starting to replace a bulb, you
must first always switch off the consumer
concerned.

Do not touch the glass part of the new
bulb with bare fingers because the finger
marks left on the glass evaporate when
the bulb becomes hot, the vapour settles
on the reflector and dims it.

Always use the same type of bulb. The
designation is marked on the base of the
bulb or on the glass.

It is advisable to always a carry a box of
spare bulbs in the vehicle. It should con-
tain at least the following bulbs which are
essential for traffic safety.

To  access the  original speakers you  must
remove  the  entire  door  panel.  Since  this
operation  requires special tools and
expertise,  we  recommend  that this be
undertaken by a Technical Service Centre.

•

The radio and loudspeakers should

therefore  be  fitted  by a  Technical Service
Centre, who are perfectly conversant with
all the  technical specificities of the  vehi-
cles,  and  have  Original Radios

and all

the necessary spares from the SEAT
Original Parts Program

. Moreover, all

work is carried out according to factory
standards.

•

The radios from the SEAT Original

Accessories program

correspond to fac-

tory models and guarantee a trouble-free
installation. These radios are fitted with
advanced technology and are easy-to-
use.

•

It is also advisable to use speakers,

assembly kits, antennas and anti-parasite
kits from the Original Accessories pro-
gram
