Solution

1. Preparation

Tools Required: Tesla app for diagnostics, tire pressure gauge, energy monitoring software.
Review all findings from diagnostic steps before proceeding.
Ensure the vehicle is parked on a level surface and has sufficient charge to perform tests.

2. Update Software

Connect the vehicle to Wi-Fi.
Navigate to the software update section in the vehicle's settings.
Download and install any available updates.
Restart the vehicle if prompted.

3. Perform Battery Calibration

Fully charge the battery to 100%.
Drive the vehicle until the battery is nearly empty (around 5%).
Charge back to 100% without stopping to recalibrate battery management settings.

4. Optimize Tire Pressure and Condition

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

5. Adjust Climate Control Settings

Reduce or optimize climate control settings while driving.
Utilize seat heaters instead of cabin heating when possible to save energy.
Limit use of air conditioning and heated seats during range tests.

6. Monitor and Analyze Energy Consumption

Access energy usage statistics through the Tesla interface.
Identify any unusual drains by reviewing accessory usage, including lights, wipers, and entertainment systems.
Adjust driving habits to optimize energy efficiency, such as using regenerative braking and avoiding rapid acceleration.
