Cold-weather tips
- 1
Don't judge it by bZ4X reviews
Older reviews describing poor winter charging and no heat pump apply to the pre-2026 bZ4X, not the redesigned bZ.
- 2
Schedule departure while plugged in
Warms the cabin and battery from wall power before you leave.
- 3
Use built-in navigation to DC chargers
Triggers the new automatic preconditioning feature ahead of arrival.
- 4
Use seat and wheel heat
Contact heat is cheaper than blasting the cabin on short trips.
