Avoid spinning wheels fitted with snow chains.



Observe recommended maximum speed of 30 MPH (50 km/h) on roads that are well covered with snow.



Immediately after fitting and after driving a short distance (150–300 ft/50 – 100 m): Check that snow
chains are perfectly centered and re-tension if necessary.



After a distance of 12 miles (20 km) and after test emergency braking: Check that snow chains are
installed correctly and check for signs of wear.



If the installed snow chain hits/touches against a curb: Check that the snow chain is installed correctly
and check for signs of wear.



Before starting EVERY trip: Check that the snow chain is fitted/positioned correctly on the wheel.

When towing a trailer, follow the instructions in the Owner’s Manual and observe all road traffic laws.
WARNING

Fitting/removing snow chains
•

Danger of injury

•

Risk of damage to the wheel housing, fender and other vehicle parts



Learn how to handle snow chains by installing/removing them when dry as a test.



AFTER installation: Check clearance of the wheel WITH snow chain in extreme positions (compressed).



Always fit/remove snow chains on level ground.



Always fit/remove snow chains when the vehicle is stationary and secured as described in the Owner’s
Manual.



As soon as the wheel fitted with the chain moves: Keep ALL parts of the body (fingers, hands and hair) a
safe distance away.



When tightening and loosening the tensioner: Keep ALL parts of the body (fingers, hands and hair) a safe
distance away.



For greater visibility and for your own safety when installing/removing snow chains, wear a Hi-vis jacket

WARNING
Using snow chains
•

Danger of injury

•

Risk of material damage



Snow chains may ONLY be used if the vehicle and tire and rim combination have been approved by
Porsche for the use of snow chains.



Incorrect and improper use of snow chains, e.g. pulling, lifting or other actions, is NOT permitted! After
fitting snow chains correctly, ONLY use them for driving on suitable surfaces.



The use of one snow chain is NOT permitted. ALWAYS use snow chains on the left and right side of the
vehicle when fitting them on the rear axle.



Visually check previously used snow chains before fitting. Damaged or broken snow chains must NEVER
be used. This applies even if the wire diameter of a chain link is more than half worn in just a small area.



Broken chain elements can be repaired at retail outlets. ONLY use genuine spare parts for repairs.



After use: Clean/wash snow chains and leave them to dry. Store snow chains away from damaging
chemicals.

Please inform the customer of this accordingly.
