Restart the vehicle after the update is complete.

3. Tire Maintenance

Use a tire pressure gauge to check all four tires:
- Inflate tires to the recommended pressure listed on the driver's door jamb.
Inspect tires for uneven wear or damage:
- If any damage is found, replace the affected tire.

4. Energy Consumption Management

Access the energy app on the display:
- Review driving habits and adjust to more efficient driving styles (e.g., smooth acceleration).
Monitor climate control settings, adjusting when possible to conserve battery power.

5. Battery Health Inspection

Use the Tesla app to check battery health:
- If the battery health is significantly degraded (below 70%), consider contacting Tesla for battery servicing or replacement options.
