When you drive with Hakkapelittas in the snow, you fall back in love with your Volvo all over again. Even in 12 inches of snow, Volvos hug the road. They suggest people check weather reports to become aware of road conditions ahead of time, and let other people know their route and the estimated time of arrival. Remember that while you need more power from your battery in the winter, batteries lose power as temperatures drop. Make sure they have the proper pressure, or consider replacing them with snow tires.
Cars can and do overheat in the winter.
But be sure to remove them in the spring because they re heavy and add to the wear and tear of your wiper motor. Keep the window slightly open to avoid carbon monoxide poisoning.
