⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is in park mode and stationary before performing any inspections or adjustments.

Symptoms

•Increased energy consumption displayed on the vehicle's energy monitor
•Reduced driving range per charge
•Unusual noises from the electric motor or drivetrain
•Heating or cooling system operating inefficiently
•Frequent battery charging needed compared to normal usage
•Possible alerts or messages regarding energy use in the vehicle's display

Diagnostic Steps

1
Check the vehicle's energy consumption report for abnormal patterns using the Tesla app or in-car display.
2
Inspect tire pressure and tread condition, ensuring they meet manufacturer specifications.
3
Look for any active alerts or notifications on the vehicle's display related to energy usage or performance.
4
Scan for error codes using the Tesla service menu or diagnostic tools.
5
Review the settings for HVAC (heating, ventilation, and air conditioning) for any excessive power use.
6
Monitor driving habits and conditions to identify any external factors affecting energy consumption.

Solution

Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and set to park mode.
Gather necessary tools such as a tire pressure gauge and OBD-II scanner (if applicable).

2. Tire Inspection and Adjustment

Check Tire Pressure:
- Use a tire pressure gauge to measure the pressure of all four tires.
- Inflate tires to the recommended PSI as stated on the driver’s door jamb.
Inspect Tire Condition:
- Look for uneven wear or damage; replace tires if necessary.

3. HVAC System Optimization

Adjust Settings:
- Set the HVAC system to eco mode or adjust the temperature settings to minimize energy consumption.
Clean Filters:
- Locate and replace or clean the cabin air filter to ensure optimal airflow and efficiency.

4. Software Update

Check for Updates:
- Connect the vehicle to Wi-Fi and navigate to the software update section in the settings.
- Install any available updates that may improve energy management.

5. Driving Habit Adjustment

Educate on Eco Driving:
- Encourage smooth acceleration and deceleration to maximize efficiency.
- Suggest using regenerative braking to recover energy during deceleration.
