wheel bolt and push it on as far as it will go.

Remove the cap with the plastic clip.

If the wheel bolt is very tight, carefully push

on the end of the wheel wrench with your

foot. Hold on to the vehicle for support and

take care not to slip during this operation.

The caps protect the wheel nuts and should

be remounted after changing the tyre.

●

Insert the wheel brace (vehicle tools) onto

the adapter as far as it will go.

The anti-theft wheel locking bolt has a

special cap. This only fits on anti-theft lock-

ing bolts and is not for use with standard

wheel nuts.

Emergencies

Important information about wheel nuts

have been tightened to the prescribed tor-

que, they could come loose while driving.

Factory-fitted rims and wheel nuts are spe-

cially matched during construction. There-

fore, if different rims are fitted, the correct

wheel nuts with the right length and heads

must be used. This ensures that wheels are

fitted securely and that the brake system

functions correctly.

●

Never loosen the screwed joints of wheel

rims with bolted ring trims.

●

If wheel nuts are tightened below the

prescribed torque, the bolts and rims could

come loose while driving. If tightening tor-

que is too high, the wheel nuts or threads

can be damaged.

In certain circumstances, you should not

even use wheel nuts from vehicles of the

same model.

jack on the vehicle.

Raise the vehicle

WARNING

●

Rest the jack (vehicles tools) on firm

ground. If necessary use a large, strong

board or similar support. If the surface is slip-

pery (for example tiles) place the jack on a

rubber mat or similar to prevent it from slip-

If the wheel nuts are not properly tight-

ened, they could come loose while driving

and cause an accident, serious injury and

loss of vehicle control.

external trim/door will (stepped on, fitting

the jack, resting heavy objects, etc.) can

cause damage to it. CUPRA accepts no re-

sponsibility for any damages caused by im-

proper use of the external trim or body.

●

Carefully lower the vehicle using the jack.

Use the wheel spanner to tighten all of the

wheel nuts clockwise. Tighten the bolts in di-

agonal pairs (not in a circle).

●

Lift the vehicle using only the jack sup-

plied from the factory. Other jacks, even

those approved for other CUPRA models

could slip, with the consequent risk of in-

jury.

●

Put the caps, trim or full hubcap back on.

The wheel nuts should be clean and turn

easily. Before fitting the spare wheel, inspect

the wheel condition and hub mounting sur-

faces. These surfaces must be clean before

fitting the wheel.

Removing and installing a wheel

●

Place the jack only at the support points

provided on the strut and align it. Other-

wise, the jack could slip because it does not

have sufficient grip on the vehicle: risk of

injury!

Change the wheel after loosening the wheel

nuts and raising the vehicle with the jack.

When removing/fitting the wheel, the rim

may hit and damage the brake disc. For this

reason, please take care and get a second

person to assist you.

Tightening torque of the wheel nuts

You should never place a body limb such

nuts for steel and alloy wheels is 140 Nm. Af-

●

Unscrew the wheel nuts using the box

spanner and place them on a clean surface.

Before checking tightening torque, have

any rusty wheel nuts that are difficult to

screw replaced and clean the wheel hub

threads.

●

Take off the wheel.

Never raise the vehicle if it is tilting to one

side or the engine is running.

Putting on the spare wheel

●

Never start the engine when the vehicle is

raised. The vehicle may come loose from

the jack due to the engine vibrations.

Check the direction of rotation of the tyre
