maintenance SKODA OCTAVIA 2012 3.G / (5E) Owner's Guide

While pressing the button, the warning light  lights up. At the same time the
system memory is erased and the new calibration is started, which is confirmed
with an audible signal and then the warning light  goes out.
If the warning light  does not go out after the calibration, this indicates a sys-
tem fault. Seek help from a ŠKODA specialist garage.
The rolling circumference of the tyre can change if: › the tyre inflation pressure is too low;
› the structure of the tyre is damaged;
› the vehicle is loaded on one side;
› the wheels of an axle are loaded heavily (e.g. when towing a trailer or when
driving uphill or downhill);
› snow chains are mounted;
› the spare wheel is mounted;
› one wheel per axle was changed.WARNING■
When the warning light  illuminates, immediately reduce the speed and
avoid sudden steering and brake manoeuvres. Stop the vehicle as soon as
possible and inspect the tyres and their inflation pressure.■
Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light  can be delayed or does not light up at all.

Wheel bolts
First read and observe the introductory information and safety warn-ings
on page 181.
Wheels and wheel bolts are matched to each other in terms of design. Each time
you fit other wheels, e.g. light alloy wheels or wheels with winter tyres, you must
also use the matching wheel bolts of the correct length and shape of spherical cap. This is essential to ensure that the wheels are tightly fitted and that the
brake system operates properly.

Winter tyres
First read and observe the introductory information and safety warn-
ings
on page 181.
The handling of your vehicle will be significantly improved when driving on wintry roads if you fit winter tyres. Summer tyres on ice, snee and at temperatures be-
low 7 °C have less grip. This is especially true of low-profile tyres or high-speed
tyres .
To achieve the best possible handling properties, winter tyres must be fitted on
all 4 wheels, the minimum tread depth must be 4 mm and tyres must be no older than 4 years.
Winter tyres of a lower speed category can be used provided that the permissible
maximum speed of these tyres is not exceeded even if the possible maximum
speed of the vehicle is higher.
The winter tyres speed limit is set in the menu » operating instructions for Info-
tainment , chapter Setting vehicle systems (CAR button) .
For the sake of the environment
Fit the summer tyres on again in good time as they provide better handling prop-
erties, a shorter braking distance, less tyre noise, and reduced tyre wear on roadswhich are free of snow and ice as well as at temperatures above 7 °C. The fuelconsumption is also lower.
Snow chains
First read and observe the introductory information and safety warn-
ings
on page 181.
When driving on wintry roads, snow chains improve not only traction, but also the
braking performance.
Snow chains must only be mounted on the front wheels.
For technical reasons, it is only permissible to fit snow chains with the following wheel/tyre combinations.
Wheel sizeDepth (D)Tyre size6J x 15 a)43 mm195/65 R156J x 16 b)48 mm205/55 R166J x 17b)48 mm205/50 R17a)
Only fit snow chains with links and locks not larger than 13 mm.
b)
Only fit snow chains with links and locks not larger than 12 mm.
Remove the full wheel trims before installing the snow chains. 
