Cold Weather Best Practices

To ensure that Model 3 provides you with the best ownership experience possible in harsh cold weather conditions, follow these best practices.

Before Driving

When snow and ice accumulate on your vehicle, moving parts, such as the door handles, windows, mirrors, and wipers can freeze in place. To achieve maximum range and performance, it is helpful to warm the cabin and Battery before driving. There are several ways to do so:

Touch Controls > Schedule (also available on both the charging and climate control screens) to set a time when you want your vehicle to be ready to drive (see Scheduled Precondition and Charge).
In the mobile app, navigate to Climate to customize the temperature at which you want to heat the cabin. This also warms the high voltage Battery as needed.
In the mobile app, navigate to Climate > Defrost Car to melt snow, ice, and frost on the windshield, charge port (if equipped), windows, and mirrors. This also warms the high voltage Battery as needed.
Note
Tesla recommends activating climate settings at least 30-45 minutes before departure (see Operating Climate Controls). Preconditioning times depend on outside temperature and other factors. The mobile app will notify you once your vehicle has reached the desired preconditioning temperature.

Charge Port

If your charge port latch freezes in place and a charging cable becomes stuck in the charge port, try manually releasing the charge cable. See Manually Releasing Charge Cable.

In extremely cold weather or icy conditions, it is possible that your charge port latch may freeze in place. In these weather conditions, on some vehicles, you can thaw ice on the charge port latch so the charge cable can be removed and inserted. To do so, enable Defrost Car using the mobile app.

You can also prevent the occurrence of a charge port latch freezing in place by using the Schedule settings (see Scheduled Precondition and Charge).

Note

If your charge port latch is frozen in place, it may not lock the charging cable in place when inserted, but it can still charge at a slow AC rate even if the latch is not engaged.

Charging

By using Trip Planner (if available) to navigate to a Tesla charging location, Model 3 pre-heats the high voltage Battery to ensure when you arrive at the charger, the temperature of the Battery is optimal and ready to charge. This reduces the amount of time it takes to charge. See (see Trip Planner).

Note

Tesla recommends using Trip Planner to navigate to a charging location for at least 30-45 minutes before arrival to ensure optimal Battery temperature and charging conditions. If the drive to the charging location is less than 30-45 minutes, consider preconditioning the Battery before driving (see Before Driving).

Note

The thermal system may produce steam under certain conditions for vehicles equipped with a heat pump (to determine if your vehicle has a heat pump, touch Controls > Software > Additional Vehicle Information). For example, odorless steam can come from the front of your vehicle while charging at a Supercharger in cold temperature. This is normal and not a cause for concern.

Windows

In the mobile app, go to Climate and select Defrost Car, which helps melt snow, ice, and frost on the windshield, windows, and mirrors.

In cold temperatures, Model 3 automatically makes a slight adjustment to the position of the windows to make it easier to open doors.

Note

Always connect to an external, low voltage power supply before opening a door when the vehicle has no power to avoid breaking a window.

Use the mobile app to schedule a service appointment for Tesla to provide hydrophobic coating to the side and rear windows (not the front windshield) for a nominal fee.

Doors

In severe winter conditions, ice buildup can make it more difficult to open door handles. You can use the mobile app to pop open the driver door in this situation.

In the mobile app, touch and hold any of the four quick control buttons and follow the instructions to customize quick controls with Unlatch Door.
When you are next to your car, touch Unlatch Door to pop open the driver door.

Removing Ice From Door Handle

In severe winter conditions, ice buildup within the door handle can prevent the door handle from opening. The process for freeing a Model 3 door handle is slightly different than others to remove ice buildup.

Note

Preemptively applying WD-40 to the door handle pivot pins can help prevent ice buildup inside your door handle.

CAUTION

Do not attempt to use tools or excessive force to release the door handle from ice buildup.

If your vehicle's door handles are black: Perform the following to remove ice from the door handle:

Forcefully press the frontmost part of the door handle. It will rock slightly inward to help break the ice.
Press the rearmost part of the door handle to try to open as you normally would.
Once the door handle is able to move, open and close it a few more times to release any remaining ice buildup. Make sure the door handle is fully pressed in (retracted) prior to entering the vehicle, and check that the door is fully closed before driving away.

If your vehicle's door handles are silver: You can usually remove the ice with a few forceful bumps to the door handle using the bottom of your fist. Perform the following to remove ice from the door handle:

CAUTION

Remove any jewelry or objects that can damage the paint prior to performing the procedure, and do not attempt to use tools or excessive force.

Forcefully press the rearmost part of the door handle to try to open the door handle.
Working in a circular pattern around the perimeter of the door handle, use the bottom of your fist to forcefully bump the door handle to break and release the ice buildup.
Aiming for the rearmost end of the wide part of the door handle, use the bottom of your fist to forcefully bump the door handle. Increase the intensity of the bumps as necessary, repeating steps 1 through 3 until the ice is removed and the door handle can be opened.
CAUTION
Never bump the vehicle so hard as to cause a dent; the force used should be similar to knocking on your neighbor’s front door.
Once the door handle is able to move, open and close it a few more times to release any remaining ice buildup. Make sure the door handle is fully pressed in (retracted) prior to entering the vehicle, and check that the door is fully closed before driving away.

Mirrors

If ice buildup is expected when parking, turn off Auto-Fold Mirrors. Touch Controls > Auto-Fold. Ice can prevent exterior side mirrors from folding or unfolding.

Note

Side mirrors automatically heat as needed during preconditioning, or when the rear defroster is turned on.

Wipers

If you expect snow or ice to build up when parked, touch Controls > Service > Wiper Service Mode. This raises the wipers against the windshield so they can defrost when the windshield defrosts (see Wipers and Washers). You can also turn on wiper defrosters (if equipped). See Operating Climate Controls.

Tires and Tire Chains

Use winter tires to increase traction in snowy or icy conditions. You can purchase winter tires on the Tesla Shop (see Seasonal Tire Types).

Tire chains provide additional traction when driving in snowy or icy conditions. Check local regulations to determine if tire chains are recommended or required during winter months. See Using Tire Chains for more information.

Your vehicle’s tire pressures will drop in cold ambient temperatures. If the TPMS indicator light appears, inflate the tires before driving. The tires will lose one PSI for every 10° F (6° C) drop in outside temperature (see Tire Care and Maintenance). Proper tire pressures help protect tires from potholes and improve range when properly inflated.

While Driving

Cold weather can increase energy consumption because more power is required for driving, cabin and Battery heating. Follow these suggestions to reduce energy consumption:

Use seat heaters to keep warm. Seat heaters use less energy than the cabin heater. Lowering the cabin temperature and using seat heaters reduces energy consumption (see Operating Climate Controls).
Slow down your driving and avoid frequent and rapid acceleration.
If your vehicle is equipped with a heat pump (to determine if your vehicle has a heat pump, touch Controls > Software > Additional Vehicle Information), you can improve the efficiency of the cabin heating by reducing your selected acceleration mode (see Acceleration Modes). This allows the heat pump system to take more heat from the Battery to efficiently heat the cabin, instead of maintaining the Battery's ability to provide peak acceleration performance. This helps to maximize driving efficiency in colder weather. Note that when subsequently increasing the acceleration mode, the Battery requires time to warm up before the increased level of acceleration is available.

Regenerative Braking

Regenerative braking can be limited if the Battery is too cold. As you continue to drive, the Battery warms up and regenerative power increases (see Regenerative Braking).

Note

Limited regenerative braking can be avoided if you allow enough time to precondition your vehicle or if you use Schedule to precondition Model 3 before your departure time (see Scheduled Precondition and Charge).

Note

Installing winter tires can result in temporarily reduced regenerative braking power but after a short period of driving, Model 3 recalibrates to correct this. Touch Service > Wheel & Tire > Tires to select winter tires and quicken this process.

Cold Battery

A blue snowflake icon appears on your touchscreen when some of the stored energy in the Battery is unavailable because the Battery is cold. This portion of unavailable energy displays in blue on the Battery meter. Regenerative braking, acceleration, and charging rates may be limited. The snowflake icon no longer displays when the Battery is sufficiently warm.

After Driving

Leave Model 3 plugged in when not in use. This uses the charging system, rather than the Battery itself, to keep the Battery warm (see High Voltage Battery Information).

Scheduled Precondition

When parked, use the Controls > Schedule settings, available on both the charging and climate control screens, to set a time when you want to precondition Model 3 (see Scheduled Precondition and Charge). You can also use Schedule to prevent the charge port latch freezing in place. Your vehicle determines the appropriate time to begin preconditioning so that cabin and Battery are warm by your planned departure time.

Tesla recommends that you also schedule a charge with your precondition to ensure that your vehicle has sufficient energy for the trip. When Model 3 is not plugged in, preconditioning operates but only when the Battery's charge level is above 20%.

Storage

If you leave Model 3 parked for an extended period of time, plug the vehicle into a charger to prevent normal range loss and to keep the Battery at an optimal temperature. Your vehicle is safe to stay plugged in for any length of time.

When not in use, Model 3 enters a sleep mode to conserve energy. Reduce the number of times you check your vehicle’s status on the mobile app, as this automatically wakes up your vehicle and starts normal energy consumption.
