2. Inflate tires to the manufacturer-recommended PSI if they are low.
3. Inspect tire tread depth using a tread depth gauge; replace tires if tread is below minimum standards.
Tools Required: Tire pressure gauge, tire inflator, tread depth gauge.

3. Driving Habit Adjustment

Sub-steps:
1. Review the last few driving logs to identify aggressive driving patterns.
2. Encourage smoother acceleration and deceleration for improved efficiency.
3. Limit high-speed driving and utilize regenerative braking effectively.
Tools Required: None.

4. Climate Control Optimizations

Sub-steps:
1. Adjust climate control settings to a moderate temperature.
2. Use seat heaters instead of cabin heating when possible.
3. Consider pre-conditioning the vehicle while it is still plugged in to minimize battery drain.
Tools Required: None.
