1. TCOO
Winter With Your Tesla

2. Woah, It’s Cold!

3. Preheat Battery
Preheating the cabin does not necessarily preheat the battery.
Once you start driving, the battery is being heated by the heat scavenged from the motor & inverter (along with cell heat generated by chemical process).
Plugging into Level 2 will not necessarily engage battery heater.
Plugging into Level 3 will engage battery heater.
Schedule your charge to end at your planned time of departure.

4. Preheat Battery Advantages: Disadvantage: Full Regen
Consistent driving experience
Safer *
Disadvantage:
Inefficient
Reduced range if not on shore power

5. Preheat Battery

6. Frozen Extremities Prevention
There’s no heat under that frunk!
Mirrors:
Turn off auto-fold
Turn off auto-tilt *
Wipers:
Put in service mode
Use de-icing washer fluid

7. Frozen Extremities Prevention
Door Handles:
Polish *
Charge Port Door:
* Polish: Pro Honda - Spray Cleaner & Polish
 The Original - Spray Cleaner & Polish

8. Frozen Extremities Prevention
Windows:
Weatherstrip Lubricant
Based on DuPont Krytox
Silicone Lubricant
Water based is okay
Don’t use petroleum / alcohol based
Dielectric Grease

9. Frozen Extremities Tools & Tips
Carefully crack the ice
Bondo Spreader
Spudger

10. Frozen Extremities Tools & Tips
Do not chisel the ice
Do not break / smash the ice
Don not peel the ice
Do not use warm / hot water

11. Winter Tires Air pressure typically drops 1-2 psi per 10 degrees F.
Tread Depth Minimum:
State – 2/32”
Summer – 3/32”
Winter – 4/32”
Directional tread increases performance, but can increase cupping.

12. Winter Tires
Summer tires shouldn't be used below 45°F, and never on ice or snow.
All-Season tires will not perform as well as winter tires when it gets below 45°F, regardless of snow/ice or not.
RWD cars will benefit most from winter tires, but AWD cars will benefit as well.
If you have low profile tires for summer, you'll also benefit from a higher profile winter tire. This will save you from bent wheels and blowouts due to ice holes and potholes.

13. Higher Energy Consumption
20-30% increase on average.
Denser air leads to increased friction.
Road debris increases rolling resistance.
Snow on vehicle reduces aerodynamics.
Colder temps require running a resistive cabin heater, seat heaters, defrost.
Colder temps require the battery heater to run to maintain a safe minimum temperature.
Running the heaters to preheat the vehicle prior to departure.

14. Reduced Energy Available
Some lost range isn’t consumed.
Cell chemistry requires a minimum temperature to release full capacity.
As cells cool, internal resistance increases.
This reduces charge rate when battery is cold. .

15. Winter Driving Tips Turn on Chill Mode. Turn on Range Mode.
Set Regenerative Braking to Low.
Clear off all sensors, cameras, radar.
Clear all snow, as it won’t melt away.
TACC requires both radar & front camera.
