WARNING
Information regarding tyre damage or wear
Never use tyres if you do not know anything about the condition and age.
■
Never drive with damaged tyres – risk of accident!
■
Immediately replace damaged wheel rims or tyres.
■
You must have your tyres replaced with new ones at the latest when the
■
wear indicators have been worn down.
Worn tyres impair necessary adhesion to the road surface, particularly at
■
high speeds on wet roads. This could lead to "aquaplaning" (uncontrolled
vehicle movement – "swimming" on a wet road surface).
WARNING
Information on tyre pressure
The tyre control display does not absolve the driver of the responsibility
■
to ensure the correct tyre inflation pressure. Check the tyre inflation pres-
sure at regular intervals.
Insufficient or excessive inflation pressure impairs handling – risk of acci-
■
dent!
If the inflation pressure is too low, the tyre will have to overcome a higher
■
rolling resistance. This will cause a significant increase in the temperature
of the tyre, especially at higher speeds. This can result in tread separation
and a tyre blowout.
WARNING
Information on the wheel bolts
The wheel bolts must be clean and must turn easily. Never treat them
■
with grease or oil.
The prescribed tightening torque of the wheel bolts for steel and light al-
■
loy wheels is 120 Nm.
If the wheel bolts are tightened to a too low tightening torque, the rims
■
could come loose when the car is moving – risk of accident! A tightening
torque which is too high can damage the bolts and threads and this can re-
sult in permanent deformation of the contact surfaces on the rims.
In case of incorrect treatment of the wheel bolts, the wheel can loosen
■
when the car is moving – risk of accident!

General Maintenance
WARNING
Information on the temporary spare wheel
Only use the temporary spare wheel when absolutely necessary.
■
Never drive with more than one temporary spare wheel mounted.
■
The snow chains cannot be used on the temporary spare wheel.
■
CAUTION
If a spare wheel is used that is not identical to the fitted tyres, the following
■
must be observed » page 155, Spare and temporary spare wheel.
Protect the tyres from contact with oil, grease and fuel.
■
Replace lost valve caps.
■
If, in the event of a puncture, it is necessary to fit a spare wheel with a tyre
■
without a dedicated running direction or with the opposite direction of rota-
tion, drive carefully as the optimal characteristics of the tyre are no longer ap-
plicable in this situation.
For the sake of the environment
Tyres that are insufficiently inflated increase your fuel consumption.
Note
We recommend that any work on the wheels or tyres be carried out by a spe-
■
cialist garage.
We recommend that you use wheel rims, tyres, full wheel trims and snow
■
chains from ŠKODA Original Accessories.
