Tesla blue snowflake symbol indicates cold battery affecting performance

BGR reported that Tesla drivers may notice a blue snowflake symbol indicating their vehicle's battery is cold, which can affect regenerative braking, acceleration, and charging speeds.

When the battery is cold, regenerative braking is reduced, causing the car to slow down less when the accelerator is released, so drivers may need to use the brake pedal more frequently, especially near junctions and traffic lights.

Acceleration power is also temporarily limited, making the car feel less responsive during maneuvers such as pulling away, merging, or overtaking. Charging speeds may slow because a cold battery cannot accept energy as quickly as when warm.

Tesla vehicles can precondition the battery by warming it while driving to a Supercharger station, which helps restore fast charging speeds. Drivers can also precondition the battery and cabin before driving by using the touchscreen Schedule feature or the mobile app, ideally 30-45 minutes before departure.

To preserve range in cold conditions, Tesla recommends using seat heaters instead of the cabin heater, as seat heaters consume less energy, allowing the car to drive further on the saved power.
