Minor Repairs
f Fit winter tyres to both axles in good time
before the cold season begins.
Your Porsche partner will be pleased to advise
you.
Maintenance note
We recommend fitting winter tyres on the vehicle
at temperatures below 7 °C since the driving
performance of summer tyres is reduced at low
temperatures. Summer tyres may be permanently
damaged at extremely low temperatures.
Winter tyres lose their suitability when their tread
depth falls below 4 mm.
f Please note that in addition to winter tyres, all-
season and all-terrain tyres also belong to the
category M+S tyres.
Wheel change
f When wheels are removed, mark the direction
of rotation and position of each wheel.
Example: FR (front right), FL, RR and RL.
f Always fit the wheels in accordance with their
marking.
Snow chains
Optimal handling characteristics can be achieved
only when snow chains are fitted on all four wheels
of the vehicle. It is also possible to fit snow chains
on only one axle (preferably the rear axle).
f Remove spacers if 18 inch tyres, snow chains
or a collapsible spare wheel are mounted.
Caution!
Risk of damage to the wheel housings if the
spacers on the rear axle are not removed
before fitting snow chains.
f The 17 mm spacers must always be removed
from the rear axle when snow chains are to be
fitted.
f For information on the spacers:
Please observe the chapter "SPACERS" on
Page 292.
For information on removing the spacers:
Please observe the chapter "CHANGING A
WHEEL WITH REMOVAL OF 17 MM SPACERS"
on Page 302.
f Use only the fine-link snow chains recom-
mended and authorised by Porsche so that
sufficient clearance between the wheel well
and the chain is assured.
