Installation and Conversion Instructions Panamera (971) 34/16 ENU 4439 4 Snow Chain DANGER Driving with snow chains • Danger of injury • Risk of material damage Snow chains may ONLY be used for driving on snow-covered and icy roads. On partly snow-covered roads: Drive much more slowly. Driving with snow chains in off-road areas has NOT been tested and approved. Allow for change in vehicle handling (see also Owner's Manual). Avoid spinning wheels installed with snow chains. Observe recommended maximum speed of 30 MPH (50 km/h) on roads that are well covered with snow. Immediately after installing 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 installed/positioned correctly on the wheel. When towing a trailer, follow the instructions in the Owner’s Manual and observe all road traffic laws. WARNING Installing/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 install/remove snow chains on level ground. Always install/remove snow chains when the vehicle is stationary and secured as described in the Owner’s Manual. As soon as the wheel installed with the chain moves: Keep ALL parts of the body (fingers, hands and hair) a safe distance away. Tequipment Dec 4, 2023 Page 1 of 10 4 Panamera (971) 4439 ENU 34/16 Installation and Conversion Instructions 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 (e.g. from PORSCHE TEQUIPMENT). Read the Installation and Conversion Instructions carefully and follow these instructions exactly during installation/removal. Observe the specified tire pressure (see Owner's Manual). Reducing the tire pressure for installation/removal is NOT permitted. Observe the snow chains' substantial own weight. 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 installing 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 installing them on the rear axle. Visually check previously used snow chains before installing. 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. Information For further information/instructions for using snow chains, see “Tires and wheels” “Using snow chains” in the Panamera Owner’s Manual.

Snow chain maintenance • • • • • Wash snow chain in hot water immediately after use and dry it. Visually inspect the snow chain for signs of Figure 16 damage and adequate wire strength (chain links). Snow chains must NOT be oiled! Spray snow chains with commercially available anti-rust agent if necessary. After drying, stow dry snow chains back in the vehicle if necessary. Snow chains are made of high-quality steel, but are not rust-resistant. A small amount of rust will not impair the quality of the snow chains. 44 39 24 00: –Snow chains (2 pieces) installed on the rear axle– Includes: Read instructions.
