Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a flat surface.
Ensure the vehicle is turned off and the key fob is out of range.

2. Update Software

Connect the vehicle to Wi-Fi.
Navigate to ‘Software’ in the main menu.
Check for updates and install any available updates.

3. Battery Health Assessment

Open the Tesla app and navigate to ‘Battery’ settings.
Check the current state of charge and overall battery health.
If the battery health is below 70%, consider contacting Tesla for further assessment.

4. Tire Check

Use a tire pressure gauge to measure tire pressure.
Inflate tires to the recommended PSI listed on the driver's door jamb.
Inspect tires for uneven wear or damage; replace if necessary.

5. Optimize Driving Settings

Go to ‘Controls’ > ‘Driving’ and enable ‘Chill Mode’ for better range.
Reduce use of climate control settings, or use seat heaters instead of cabin heating.
