⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is parked securely before making any adjustments or checks.

Symptoms

•Decreased driving range compared to manufacturer specifications
•Frequent need for recharging
•Battery percentage dropping rapidly during normal driving conditions
•Possible warning messages related to battery health or efficiency
•Increased energy consumption readings on the vehicle's energy display

Diagnostic Steps

1
Use the Tesla app or vehicle interface to check for software updates and install any available updates.
2
Access the energy consumption graph in the vehicle's display to identify patterns in energy usage.
3
Monitor the vehicle's driving habits, including acceleration, speed, and climate control settings.
4
Inspect for any active accessories that may be drawing power, such as air conditioning or heated seats.
5
Review the tire pressure and condition, as under-inflated or worn tires can increase rolling resistance and energy consumption.
6
Conduct a battery health check through the vehicle's diagnostics to assess any potential battery degradation.
