Tesla in winter: preconditioning, charging and ice

How to prepare your Tesla for cold weather, from Tesla’s own manual: preconditioning with Schedule, warming the battery before fast charging, frozen charge ports, icy handles, mirrors and wipers, tyre pressure and range.

Short answer

Warm the car before you leave: set a Schedule or start Climate in the app 30–45 minutes ahead, ideally while plugged in. Navigate to a fast charger with Trip Planner so the battery arrives warm. Use Defrost Car for ice on the windows, mirrors and charge port, put the wipers in Wiper Service Mode before snow, turn off mirror auto-fold when ice is expected, and check tyre pressure as it drops in the cold.

Warm the car before you leave

Tesla recommends starting climate 30–45 minutes before departure. You have three ways:

Controls › Schedule sets a ready-by time; the car decides when to start so the cabin and battery are warm when you leave. Tesla suggests scheduling a charge with it.
In the Tesla app, Climate heats the cabin and warms the battery as needed.
Climate › Defrost Car in the app melts snow, ice and frost on the windshield, windows, mirrors and charge port.

The app tells you when the car has reached temperature. Unplugged, preconditioning runs unless the car is in Low Power Mode, so leave it plugged in when you can.

The blue snowflake and a cold battery

A blue snowflake on the touchscreen means part of the battery’s energy is unavailable because the battery is cold; that part shows in blue on the battery meter. Regenerative braking, acceleration and charging may be limited until it warms up. Preconditioning with Schedule avoids most of this. Leaving the car plugged in lets the charger, not the battery, keep the battery warm.

Charging in the cold

Navigate to a Supercharger with Trip Planner at least 30–45 minutes before you arrive, so the battery is preheated and charges faster. If the drive is shorter, precondition before you set off.
With a heat pump, odourless steam from the front of the car while Supercharging in the cold is normal.
At home, plug in whenever the car is parked. Tesla says it is safe to stay plugged in for any length of time.

Frozen charge port

If the charge port latch freezes, use Defrost Car in the app to thaw it; a Schedule helps prevent it. A frozen latch may not lock the cable, but the car can still charge at a slow AC rate. Controls › Service › Inlet Heater exists only in Korea, Japan and North America. If a cable stays stuck, follow the manual’s steps for manually releasing the charge cable. More in our charge port guide.

Icy doors, handles and windows

In the cold, windows stop slightly below the trim when fully closed, so they don’t freeze and the doors open more easily.
The Tesla app’s Unlatch Door quick control pops the driver door open when a handle is iced up: touch and hold a quick control to add it.
For an iced Model Y handle, press the front part firmly, then press the rear part as normal, and work it a few more times. Tesla suggests WD-40 on the handle pivot pins to prevent ice. Don’t use tools or force.
Tesla can apply a hydrophobic coating to the side and rear windows (not the windshield) for a fee; book it as a service appointment in the app.

If a passenger door is iced, Handlefree Pro can unlatch exactly that door once you have tested it, though a frozen seal can still hold it shut. See when a Tesla door won’t open.

Mirrors and wipers

If you expect ice when you park, turn off mirror auto-fold (in Controls; the exact menu depends on the software version). Ice can stop the mirrors folding or unfolding. The mirrors heat during preconditioning or with the rear defroster.
Before snow or ice, use Controls › Service › Wiper Service Mode. It raises the wipers against the windshield so they defrost with it. Wiper defrosters, if equipped, are in the climate controls.

Driving, tyres and range

Seat heaters use less energy than heating the cabin. Lower the cabin temperature and use them instead.
A lower acceleration mode, such as Chill in Controls › Dynamics › Acceleration, lets the heat pump draw more heat from the battery for the cabin.
Tyre pressure drops about 1 PSI for every 10 °F (6 °C) fall in temperature. Inflate the tyres if the pressure light appears.
After fitting winter tyres, select them in Controls › Service › Wheel & Tire › Tires so regenerative braking recalibrates sooner. Check local rules on winter tyres and chains.
Every app check wakes the car and uses energy, so check less often when it is parked for long.

Questions

How long before driving should I precondition?

Tesla recommends 30–45 minutes. Times depend on the outside temperature; the app notifies you when the car is ready. For a fast charger, navigate there with Trip Planner at least 30–45 minutes before you arrive.

Why is part of my battery shown in blue?

The battery is cold, so some of its energy is temporarily unavailable. A blue snowflake appears, and regenerative braking, acceleration and charging may be limited until it warms up.

My charging cable is stuck in a frozen charge port. What now?

Turn on Defrost Car in the Tesla app to thaw the latch. The Inlet Heater setting exists only in Korea, Japan and North America. If that does not help, follow the manual’s manual cable release steps.
