Solution

1. Preparation

Gather necessary tools such as a tire pressure gauge and the Tesla mobile app.
Ensure the vehicle is parked on a level surface and is turned off.

2. Software Update

Connect the vehicle to Wi-Fi.
Go to the Software tab on the touchscreen and check for available updates.
If an update is available, follow the prompts to install it.

3. Battery Health Check

Open the Tesla app and navigate to the 'Battery' section.
Review the battery capacity and state of health (SoH) metrics.
If the battery shows significant degradation (below 70%), consider contacting Tesla service for evaluation.

4. Tire Maintenance

Use the tire pressure gauge to check all four tires.
Inflate tires to the manufacturer-recommended PSI (found on the driver's side door jamb).
Inspect tires for uneven wear or damage; replace if necessary.

5. Climate Control Adjustment

Minimize use of heating or air conditioning during drives.
Use seat heaters instead of cabin heating if needed.
Utilize preconditioning while plugged in to reduce energy use while driving.

6. Review Driving Habits

Monitor driving patterns; avoid aggressive acceleration and high speeds.
Opt for regenerative braking to maximize efficiency.
Limit use of features that drain battery, such as high-powered entertainment systems while driving.
