laser sensor function
Some parts in the engine compartment come from the factory with certifi-
cates of safety, labels or plates containing important information regarding
the operation of the vehicle, for example, on the petrol cap, on the passeng-
er's sun visor, on the driver door strut, or on the floor of the luggage com-
partment.
● Never remove these certificates of safety, labels or plates, and ensure
they are kept in good condition and are legible.
● If a vehicle part, bearing a certificate of safety, label or plate, is re-
placed, the Specialised workshop should attach the information back in the
same place.
Certificate of safety
A certificate of safety on the door strut states that all the safety standards
and regulations established by the national traffic authorities responsible
for road safety were met at the time of manufacture. It may also give the

Using your vehicle in other countries and continents
The vehicle is manufactured at the factory for use in a particular country in
accordance with the national legislation in force at the time of manufacture.
If the vehicle is sold in another country or used in another country for an ex-
tended period of time, the applicable legislation of that country should be
observed.
It may be necessary to fit or remove certain pieces of equipment or to deac-
tivate certain functions. Service work may also be affected. This is particu-
larly true if the vehicle is used in a different climate for an extended period
of time.
As there are different types of frequency bands around the world, you may
find that the radio system or the Portable Navigation System (supplied by
SEAT) supplied at the factory does not work in another country.
CAUTION
● SEAT does not accept liability for any damage to the vehicle due to the
use of a lower quality fuel, an inadequate service or the non-availability of
genuine spare parts.
● SEAT does not accept liability if the vehicle does not comply in part or in
full with the legal requirements of other countries or continents. Radio reception and the aerial
For factory-fitted radio equipment, the aerial for radio reception is fitted to
the roof of the vehicle.
Note
If electrical equipment such as mobile telephones, is used near a roof aer-
ial, you may observe interference in the reception of AM stations. 

250Practical information
Changing a wheel
Introduction
Some vehicle versions and models do not have a factory-fitted jack or box
spanner. In this case, we recommend consulting a Specialised workshop to
change the wheel.
You should only change the wheels yourself if the vehicle is parked in a safe
place, you are familiar with the procedure and you have all the necessary
tools! Otherwise, you should seek professional assistance.
Additional information and warnings:
● Exterior detail ⇒ page 6
● Vehicle key set ⇒ page 28
● Wheels and tyres ⇒ page 210
● In case of emergency ⇒ page 240
● Vehicle tools ⇒ page 246
● Wheel trims ⇒ page 248
WARNING
Changing a wheel can be dangerous, especially on the hard shoulder.
Please observe the following rules to minimise the risk of injury:
● Stop the vehicle safely as soon as possible. Park your vehicle as safe
distance from surrounding traffic to change a wheel.
● When changing a wheel, keep all passengers and particularly chil-
dren a safe distance away from the work area.
● Turn on the hazard warning lights to warn other road users.
● Ensure the ground on which you park is flat and solid. If necessary,
support the jack on a wide solid base.
WARNING (Continued)
● If you are changing a wheel yourself, you should be familiar with the
required procedure. Otherwise, you should seek professional assistance.
● Only use suitable tools that are not damaged when changing a wheel.
● Always stop the engine, apply the handbrake lever firmly and place
the selector lever in position P, or engage a gear for a manual gearbox to
reduce the risk of the vehicle moving accidentally.
● Have the tightening torque of the wheel bolts checked as soon as
possible with a reliable torque wrench.


252Practical information
If the wheel bolt is very tight, you may be able to loosen it by pushing down
on the end of the wheel brace carefully with your foot. Hold on to the vehicle
for support and take care not to slip.
Loosening wheel bolts
● Fit the wheel brace as far as it will go over the wheel bolt ⇒ Fig. 141.
● Hold the wheel brace at the end and rotate the bolt approximately one
turn anticlockwise ⇒ 
.
Loosening anti-theft wheel bolts
For wheels with full hubcap, the anti-theft wheel lock must be threaded into
position ⇒ Fig. 142 2
before mounting the hubcap. Otherwise it will not be
possible to mount the full hubcap.
● Take the adapter for anti-theft wheel bolts out of the vehicle tool kit.
● Insert the adapter onto the wheel bolt ⇒ Fig. 142. Push it on as far as it
will go.
● Fit the wheel brace onto the adapter as far as possible.
● Hold the wheel brace at the end and rotate the bolt approximately one
turn anticlockwise ⇒ 
.
Important information about wheel bolts
The wheel rims and bolts have been designed to be fitted to factory op-
tions. If different 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 some circumstances, wheel bolts from the same model vehicle should
not be used.
Wheel bolt tightening torque
The prescribed tightening torque for wheel bolts for steel and alloy wheels
is 110 Nm. Have the tightening torque of the wheel bolts checked as soon
as possible with a reliable torque wrench. If wheel bolts are rusty and it is difficult to tighten them, the threads should
be replaced and cleaned before checking the tightening torque.
Never grease or lubricate wheel bolts or the wheel hub threads. Although
they have been tightened to the prescribed torque, they could come loose
while driving.
WARNING
If the wheel bolts are not fitted correctly they could be released while
driving leading to loss of vehicle control and serious damage.
● Only use wheel bolts which correspond to the wheel rims in question.
● Never use different wheel bolts.
● The bolts and threads should be clean, free of oil and grease and easy
to thread.
● To loosen and tighten the wheel bolts, always use the wheel brace
supplied with the vehicle.
● Loosen the wheel bolts only about one turn before raising the vehicle
with the jack.
● Never grease or lubricate wheel bolts or the wheel hub threads. Al-
though they have been tightened to the prescribed torque, they could
come loose while driving.
● Never loosen the bolted joints of wheel trims with bolted ring trims.
● If the wheel bolts are not tightened to the correct torque, they may
come loose while driving, and the bolts and rims may come out. If the
tightening torque is too high, the wheel bolts and threads can be dam-
aged.

WARNING
If the wheel bolts are not treated suitably or not tightened to the correct
torque then this could lead to loss of vehicle control and to a serious ac-
cident.
● All the wheel bolts and hub threads should be clean and free of oil
and grease. The wheel bolts should be easily tightened to the correct tor-
que.
● The hexagonal socket in the wheel brace should be used for turning
wheel bolts only. Do not use it to loosen or tighten the wheel bolts.
