Remove the valve cap. 2. Firmly press an accurate tire pressure gauge onto the valve to measure pressure. 3. If required, add air to reach the recommended pressure. 4. Re-check pressure by removing and re-attaching the tire gauge. 5. If you added too much air, release air by pressing the metal stem in the center of the valve. 6. Recheck the pressure with the tire gauge and adjust if necessary. 7. Replace the valve cap to prevent dirt from entering. Periodically check the valve for damage and leaks. WARNING: Under-inflation is the most common cause of tire failures. It can cause a tire to overheat, resulting in severe tire cracking, tread separation, or blowout, which The Tire Pressure indicator light on the causes unexpected loss of vehicle control and instrument panel alerts you if one or increased risk of injury.

A hot tire at or below the detected (see page 7.6). recommended cold tire inflation pressure is dangerously under-inflated. WARNING: Do not use any tire sealant other than the type provided in a Tesla tire repair kit. Other types can cause tire pressure sensors to malfunction. If your ModelS did not include a tire repair kit, you can purchase one from Tesla Motors. MAINTENANCE 7.3
