Solution

1. Preparation

Ensure the vehicle is parked on a flat surface.
Turn off all accessories and ensure the vehicle is in park mode.

2. Battery Health Check

Access the Tesla app or vehicle display.
Navigate to the "Battery" section to review the current state of health.
If battery capacity is significantly reduced (below 70% of original), consider contacting Tesla service for a potential battery replacement or further assessment.

3. Tire Pressure Adjustment

Measure tire pressure using a digital tire pressure gauge.
Inflate tires to the recommended PSI found on the driver’s side door jamb label.
Inspect tires for uneven wear or damage, replacing if necessary.

4. Driving Habits Review

Monitor driving patterns using the Tesla's energy consumption graph.
Aim for smooth acceleration and moderate speeds to optimize range.
Avoid using "Ludicrous Mode" or aggressive driving features that increase battery drain.

5. Software Update Check

Access "Software" in the settings menu to check for pending updates.
If an update is available, follow prompts to install it, which may improve battery management and efficiency.

6. Accessory Power Management

Review settings for climate control, heated seats, and other accessories.
Set climate control to "Scheduled Departure" to optimize battery use while pre-conditioning.
