Tesla doesn't stop you from using FSD (Supervised) in snow or rain, but its own manual says poor visibility from rain, snow, fog, direct sun or low light "can significantly degrade performance," and a blinded camera can make Self-Driving features unavailable. Regulators are investigating FSD crashes in glare, fog and dust. What each condition does, the alerts, and how to keep the cameras clear this winter.
In three published winter tests of a Tesla Model 3 Long Range, keeping the cabin heated used about 2.2 to 3.3 percent of the battery per hour, or roughly 18 to 27 percent over an 8-hour night. Camp Mode also stops if the car enters Low Power Mode, which can switch on at a level you pick between 10 and 20 percent. Here are the tests, the hours you can expect, and what the manual says it turns off.
The site's electric car guides for owners and shoppers of any brand, grouped by the question that brings people here: charging at home and on the road, battery health, winter, what it costs, and buying new or used. Each entry says which question the guide settles, so you can go straight to the page you need.
The winter guides on this site, grouped by the problem that brings people here: an electric car that loses range or charges slowly in the cold, snow and ice on the road, a frozen door or charge port, a power outage, a heating bill that doubled, and a Starlink dish under snow. Each entry says which question the guide settles, so you can go straight to the page you need.
A Tesla has no snow mode button. What it has is a pair of traction settings under Controls > Dynamics whose names depend on which manual your car runs, a short list of approved snow chains, and a written procedure for rocking the car out of a drift. Here is all of it, model by model, from the manuals.
A frozen Tesla door handle opens from the app: the Unlatch Door quick control pops the driver door without touching the handle. A charging cable frozen in the port comes out with Controls, Service, Inlet Heater, which warms the port for up to two hours, and since software 2026.2.3 a Model 3 or Model Y will also release the cable if you pull and hold the rear left door handle for three seconds. Here is every fix Tesla's own manual documents, what the charge port light colors mean, and how to keep both from freezing again.
The right pressure for your Tesla is the number on the door-pillar label, and the car repeats it on the screen. The manual says tires lose about one psi for every 10°F drop, and the low-pressure alert fires when a tire is 20 percent under that label. Run the math and a correctly filled tire cannot reach the alert until about minus 8°F, which means the warning on a 30°F morning is a tire that was already low in summer.
The Model Y has had a heat pump since launch and the Cybertruck has one. Model 3s got it with the 2021 model year, and the Model S and X got it with the 2021 refresh. Older cars use a resistance heater. Here is the full table, the 30-second check Tesla prints in its own manual, and what the difference is worth in winter.
Your Tesla coasts instead of slowing, a dotted line appears on the power meter, and the screen says regenerative braking is limited. It is almost never a fault. The manual names three causes, a cold battery and a full one chief among them, warns separately about regen on ice, and offers a setting that makes the car press its own brakes to fill the gap. Here is what each sign means and how to get regen back.
Preconditioning warms a Tesla's cabin and battery before you drive or fast charge. Plugged in, the energy comes from the wall and costs you no range. Unplugged, it runs off the pack and only above 20 percent. Tesla's own manual says to allow 30 to 45 minutes, and a warm pack fast-charges in roughly the time a cold one spends just heating up. Here is how it works, what it costs and why it sometimes does not run.
Every guide says winter tires cost an electric car 5 to 10 percent of its range. None of them says what that number was measured against. Here is what the regulated data actually shows, and how to read the one figure that tells you the answer for a specific tire.
At 20°F an electric car loses about 12% of its range with the heater off and about 41% with it on. Roughly two-thirds of what you lose is spent warming the cabin, not the battery, which is why the fixes most guides recommend are the wrong ones.
Seven mistakes that cost new EV owners money, battery health or range, from paying new-car prices in the segment that loses value fastest to charging a nickel battery to 100% every night.
