⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is parked on a level surface when checking tire pressure.
•Follow manufacturer guidelines for battery maintenance and replacement.

Symptoms

•Noticeable reduction in driving range on full charge
•Frequent activation of the battery management warning
•Increased charging frequency compared to previous usage
•Decreased regenerative braking efficiency
•Unusual battery temperature readings
•Possible alerts on the vehicle's display regarding battery health

Diagnostic Steps

1
Use the Tesla app or onboard diagnostics to check for any active error codes related to the battery or energy management system.
2
Inspect the battery health report via the touchscreen to assess the overall condition of the battery pack.
3
Review recent driving habits and patterns to identify any changes in usage or driving style that may affect range.
4
Check for software updates that may improve battery performance or efficiency.
5
Examine tire pressure and condition, as under-inflated or worn tires can negatively impact range.
6
Ensure climate control settings are not excessively draining battery power during drives.

Solution

Solution

1. Battery Health Check

Sub-steps:
- Access the battery health report through the vehicle settings on the touchscreen.
- Note the battery's state of health (SoH) percentage. If it is below 70%, consider battery replacement.

2. Software Update

Sub-steps:
- Connect the vehicle to Wi-Fi.
- Navigate to the Software tab on the touchscreen.
- Download and install any pending updates.
- Restart the vehicle if prompted.

3. Tire Maintenance

Sub-steps:
- Check tire pressure using a digital tire pressure gauge.
- Inflate tires to the recommended PSI (usually found on the driver's door jamb).
- Inspect tires for any signs of wear or damage; replace if necessary.

4. Regenerative Braking Adjustment

Sub-steps:
- Access the driving settings on the touchscreen.
- Ensure regenerative braking is set to “Standard” for maximum efficiency.
- Test regenerative braking functionality by driving in a controlled environment.

5. Climate Control Optimization

Sub-steps:
- Lower the use of climate control settings to conserve battery.
- Utilize scheduled preconditioning to heat or cool the vehicle while plugged in.
- Consider using seat heaters instead of cabin heating for efficiency.
