Local winter tips
- Mountain passes drain range on the way up and regen much of it back down — plan for the climb, not the round trip average.
- Traction laws and chain requirements apply in snowstorms; carry proper winter tires or chains.
- Rapid temperature swings between valleys and passes mean your battery can be much colder than the town forecast suggests.

Altitude has minimal direct effect on the battery, but long mountain climbs consume far more energy than flat driving.
