⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is in 'Park' mode before performing checks and adjustments.

Symptoms

•Decreased driving range compared to previous usage
•Increased frequency of charging
•Battery percentage drops rapidly during short trips
•Higher energy consumption displayed in the vehicle's efficiency metrics
•Possible warnings or notifications related to battery health

Diagnostic Steps

1
Check the vehicle’s energy consumption metrics through the infotainment system.
2
Review recent software updates for any known issues or changes in energy management.
3
Inspect the tire pressure and condition, as under-inflated tires can increase energy consumption.
4
Verify the climate control settings and usage, as excessive use can drain the battery faster.
5
Run a battery health check through the Tesla app or interface to assess overall battery condition.
6
Examine for any recent changes in driving habits or additional load (e.g., roof racks, heavy cargo).

Solution

Solution

1. Preparation

Ensure the vehicle is parked on a flat surface.
Gather necessary tools and equipment.
Safety warning: Ensure the vehicle is in "Park" mode before starting work.

2. Check Tire Pressure and Condition

Tools Required: Tire pressure gauge
Steps:
1. Remove the valve cap from each tire.
2. Use the tire pressure gauge to measure the pressure.
3. Compare readings with the recommended tire pressure found on the driver’s door jamb.
4. Inflate tires to the recommended pressure if necessary.
5. Inspect tires for wear or damage; replace if needed.

3. Review Climate Control Settings

Steps:
1. Access the climate control settings via the touchscreen.
2. Reduce the temperature setting if it's excessively low.
3. Consider using seat heaters instead of cabin heating for efficiency.
4. Turn off climate control when it’s not needed, especially during short trips.

4. Monitor Driving Habits

Steps:
1. Analyze recent driving patterns via the Tesla app.
2. Identify any changes such as aggressive driving or frequent stops.
3. Adjust driving style to a more efficient mode (smooth acceleration and braking).

5. Run Battery Health Check

Steps:
1. Open the Tesla app and navigate to the battery section.
2. Review the health report provided by the app.
3. If the health is below expected levels, consider contacting Tesla service for further evaluation.
