Like all vehicles, Teslas require a little extra attention during the cold winter months. A common query among Tesla owners is the appearance of a blue snowflake icon next to the battery indicator on their vehicle's touchscreen and in the Tesla app. This icon is not just a quirky design choice; it carries important information about the state of your vehicle's battery, particularly in cold weather conditions.
What the Blue Snowflake Means
The blue snowflake icon warns that the battery is too cold to access its full power and range capabilities. When this icon is visible, owners might notice a reduction in regenerative braking and acceleration. The vehicle’s range is also reduced and charging may be slower than usual, especially at Superchargers. This is a protective measure by Tesla to prevent damage to the battery under cold conditions. The lithium-ion batteries used in Tesla vehicles, like those in other electric vehicles, are sensitive to temperature extremes. Cold temperatures can significantly impact the battery's chemical reactions, reducing its ability to store and release energy efficiently.
How Much of the Battery Is Affected
The Tesla app visually represents the battery's charge level, with the affected portion displayed in blue. By tapping on the battery icon or the charge button in the app, or similarly on the vehicle's touchscreen, users can jump to the Charging section in settings. Here, the portion of the battery displayed in blue represents the "locked" or unusable part of the battery due to cold temperatures. The extent of this blue section gives you a rough idea of how much of your battery's capacity is currently restricted.
Range Impact and Restoration
The vehicle's displayed range already accounts for the portion of the battery that is currently unusable by cold temperatures. This means the actual available range might be more than what is shown. As the battery warms up -- either through driving, charging, or preconditioning -- the additional range will be unlocked, and the blue snowflake icon will disappear. It's important to note that the colder the battery, the more range is temporarily inaccessible. Achieving normal operating temperature is crucial to unlocking this additional, temporarily unavailable range. Moreover, a cold battery can also diminish the vehicle's acceleration performance.
Why It Happens and How to Prevent It
The primary reason for this phenomenon is to safeguard the battery's integrity in cold weather. To minimize the impact of cold temperatures and prevent the snowflake icon from appearing, Tesla recommends keeping the vehicle plugged in whenever possible and maintaining a charge level above 20% when unplugged. Additionally, storing the vehicle in a garage and keeping it plugged in can help keep the battery from getting too cold. However, seeing the snowflake on colder days is still normal. Preconditioning the vehicle before use, a feature that preheats the battery and cabin can also mitigate the effects of cold weather on the battery.
Preheating enhances comfort and ensures that the battery operates efficiently from the moment you start driving, meaning that not only will you have full access to the vehicle’s power, but also its regenerative abilities and range. This approach, coupled with keeping the vehicle charged and stored in warmer conditions, can significantly reduce the occurrence of the blue snowflake icon, ensuring that your Tesla performs optimally, even in colder climates.

In last year’s holiday update, Tesla introduced the much-needed Dashcam Viewer in the Tesla app. The feature allows owners to view Dashcam and Sentry Mode footage directly from the Tesla app, eliminating the need to review videos in your vehicle. Unfortunately, the feature was limited to iPhone users, but Tesla is now changing that.
With Tesla app update 4.43.5, Tesla is officially launching the Dashcam Viewer on Android devices.
Dashcam Viewer
The Dashcam Viewer makes it easy to access and manage your car’s Dashcam and Sentry Mode videos. Accessing videos on your phone is faster and more convenient, but it does come with a few requirements.
The Dashcam Viewer in the Tesla app allows you to view, delete, or save video clips right from your device. This should result in higher quality content being shared online and fewer videos of owners recording their Tesla’s screens with their phones.
How It Works
Dashcam footage remains stored locally on your vehicle’s connected USB drive, so Tesla isn’t streaming videos to your phone from the cloud. Instead, the videos are streamed directly from your vehicle to your phone—similar to how Actually Smart Summon delivers a live feed to your phone.
Because of this, your vehicle must be connected to cellular data or Wi-Fi for the Dashcam Viewer to work. Unfortunately, this may limit access for owners who park in underground or large parking garages where connectivity is poor.
How to Access the Dashcam Viewer
To view Dashcam and Sentry Mode footage in the Tesla app:
Navigate to Security & Drivers > Dashcam Viewer.
Wait a few moments for your phone to connect to the vehicle.
From there, you’ll be able to view, save, or delete clips right from your device.
Requirements
To use Tesla’s Dashcam Viewer, you’ll need a vehicle with MCU 2 (Intel) or higher. All models are supported except for the legacy Model S and Model X (2020 and older). However, we expect support to be added in the near future.
The legacy Model S and Model X are expected to receive support for Actually Smart Summon, which requires the ability for those vehicles to stream video to the Tesla app — the same capability the Dashcam Viewer needs. Once Actually Smart Summon is added to the legacy Model S/X, we expect those vehicles to also receive the Dashcam Viewer at the same time or shortly afterward.
Tesla has imposed some viewing limits to prevent high data usage. The viewing limits apply to streaming video from the Dashcam Viewer or viewing live video from the vehicle’s cameras. Tesla will limit video streaming from the vehicle to 15 minutes or 1 hour, depending on your region.
Android Support
Tesla typically releases support for newer features to iPhone users since they make up the majority of users. Recently, Tesla has added more features to Android. In January, Tesla added support for ultra-wideband to Android, which added support for the improved phone key and the hands-free trunk and frunk feature.
Did you know the Cybertruck’s air suspension automatically levels the truck, even while it’s asleep? This is a great feature, especially for camping or off-road adventures. However, it can be an issue when lifting a wheel to change a tire.
Fortunately, there’s a solution: Jack Mode.
Jack Mode
Jack Mode is made for jacking up the truck and prevents the Cybertruck from self-leveling.
To enable Jack Mode, you’ll first need to set the Ride Height to Medium from Controls > Dynamics > Ride Height. You can also set it from the Tesla app by navigating to the Controls section and sliding up until you see Ride Height. This will give you enough clearance for most jacks to get under the truck and lift it.
You can also activate Jack Mode in Low or High, but Tesla recommends a Medium ride height for best control of the vehicle and sufficient tire clearance to safely remove and reinstall the tire. However, once the vehicle is in Jack Mode, the Ride Height cannot be changed.
Next up, go to Controls > Service > Jack Mode to enable Jack Mode. The vehicle will warn you that Jack Mode is enabled and can either be disabled by pressing the button again or by putting the vehicle into drive.
For the duration that Jack Mode is active, it is safe to lift your Cybertruck, even on one side only. It will not self-level for the duration that Jack Mode is enabled.
Automatic Jack Mode
Jack Mode can also activate automatically to protect the suspension from potential damage. For example, if the vehicle’s bumper is resting on a curb, Jack Mode may engage on its own.
Once the obstacle is cleared, or if you shift into Drive or Reverse, Jack Mode will automatically be disabled.
