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.

254Practical information
Check list
For your own safety and that of other passengers, the following points
should be observed in the order given ⇒ 
:
1. Select a suitable flat and firm surface for raising the vehicle.
2. Switch off the engine, engage a gear (manual gearbox) or place the selector lever in position P ⇒ page 124 and engage the handbrake
⇒ page 134.
3. Block the wheel diagonally opposite the wheel being changed with collapsible wheel chocks or other suitable objects.
4. Loosen the wheel bolts on the wheel to be changed ⇒ page 251.
5. Look below the vehicle for the jacking point ⇒ Fig. 143 closest to the
tyre which has to be changed.
6. Raise the jack with the handle until it can be inserted below the jack- ing point.
7. Ensure that the foot of the jack is firmly on the ground and that it is placed, at a vertical angle, immediately below the lifting point on the
vehicle ⇒ Fig. 144.
8. Straighten the jack and continue raising it using the handle until the claw holds the vertical reinforcement beneath the vehicle ⇒ Fig. 144.
9. Raise the vehicle until the wheel is clear of the ground.
WARNING
If the vehicle is not correctly raised, it could fall off the jack causing seri-
ous injury. Please observe the following rules to minimise the risk of in-
jury:
● You should only use a jack approved by SEAT for your vehicle. Other
jacks, even those approved for other SEAT models, might slip out of
place.
WARNING (Continued)
● The ground should be firm and flat. If the ground is 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 (for example, on tiles), place a non-slip sur-
face (for example a floor mat) beneath the jack to avoid slipping.
● Only fit the jack at the prescribed jacking points. The claw of the jack
should grip the reinforcement nerve on the underbody ⇒ Fig. 144.
● You should never have any limbs beneath a raised vehicle which is
only supported by a jack.
● If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!.
● Never raise the vehicle if it is tilting to one side or the engine is run-
ning.
● Never start the engine when the vehicle is raised. The vehicle may
come loose from the jack due to the engine vibrations.
WARNING
Failure to follow the checklist prepared for your own safety could lead to
accidents and severe injuries.
● Always complete the operations given in the checklist and observe
the general rules of safety.

256Practical information
Anti-puncture kit*
Introduction
The Tyre Mobility Set* will reliably seal punctures caused by the penetration
of a foreign body of up to about 4 mm in diameter. Do not remove foreign
objects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre, you must again check the tyre
pressure about 10 minutes after starting the engine.
You should only use the tire mobility set if the vehicle is parked in a safe
place, you are familiar with the procedure and you have the necessary tire
mobility set! Otherwise, you should seek professional assistance.
The tyre sealant must not be used in the following cases:
● If the wheel rim has been damaged.
● In outside temperatures below -20 °C (-4 °F).
● In the event of cuts or perforations in the tyre greater than 4 mm.
● If you have been driving with very low pressure or a completely flat tyre.
● If the sealant bottle has passes its use by date.

● In case of emergency ⇒ page 240
● Wheel trims ⇒ page 248
WARNING
Using the tire mobility set can be dangerous, especially when filling the
tyre at the roadside. 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 fill the tyre.
● Ensure the ground on which you park is flat and solid.
● All passengers and particularly children must keep a safe distance
from the work area.
● Turn on the hazard warning lights to warn other road users.
● Use the tire mobility set only if you are familiar with the necessary
procedure. Otherwise, you should seek professional assistance.
● The tire mobility set is intended for temporary, emergency use only.
Use only until you can reach the nearest specialised workshop.
● Replace the repaired tyre with the tire mobility set as soon as possi-
ble.
● The sealant is a health hazard and must be cleaned immediately if it
comes into contact with the skin.
● Always keep the tire mobility set out of the reach of small children.
● Never use the approved jack, even if it has been approved for your ve-
hicle.
● Always stop the engine, apply the handbrake lever firmly and engage
gear if using a manual gearbox, in order to reduce the risk of vehicle in-
voluntary movement.

Information for replacing bulbs
Checklist
To replace a bulb, carry out the following operations always in the order giv-
en ⇒ 
:
1. Park the vehicle a safe distance from traffic and on suitable ground.
2. Apply the handbrake firmly ⇒ page 134.
3. Turn the light switch to position 0 ⇒ page 84.
4. Move the gear lever into the neutral position ⇒ page 84.
5. Stop the engine and remove the key from the ignition ⇒ page 119.
6. Automatic gearbox: move the selector lever to position P
⇒ page 124.
7. Manual gearbox: Select a gear ⇒ page 124.
8. Allow the corresponding bulb to cool.
9. Visually inspect fuses to see if any are blown ⇒ page 261.
10. Replace the bulb according to the instructions ⇒ 
. Bulbs should
only be replaced by new identical models. Bulb information is dis-
played on the bulb socket or on the bulb itself.
11. In general, never touch the bulb glass directly. The heat of the bulb would cause the fingerprint to evaporate and condense on the reflec-
tor. This will impair the brightness of the headlight.
12. Check if the new bulb is working. If the bulb is not working, it maynot have been correctly fitted, it could be damaged or the connector
may not be correctly connected.
13. Every time a bulb for the headlights is replaced, visit a specialised workshop to check the headlights.
WARNING
Failure to follow the checklist prepared for your own safety could lead to
accidents and severe injuries.
● Always complete the operations given in the checklist and observe
the general rules of safety.
CAUTION
Always remove and fit headlights carefully to avoid damage to the paint-
work and other vehicle parts. 

Practical information
Starting
5. Start the engine of the vehicle with the boosting battery and let it run at idling speed.
6. Start the engine of the vehicle with the flat battery and wait one or two minutes until the engine is “running”.
Removing the jump leads
7. Before you remove the jump leads, switch off the headlights (if they are switched on).
8. When the engine is running, disconnect the leads in reverse or- der to the details given above.
Connect the battery clamps so they have good metal-to-metal contact with
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and
try again after about half a minute.
WARNING
● Please note the safety warnings referring to working in the engine
compartment ⇒ page 182.
● 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, dan-
ger of explosion. Failure to comply could result in an explosion.
WARNING (Continued)
● 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 attached 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. 
