Many modern cars feature folding mirrors that can be activated from inside the cabin or when the car’s alarm engages. Some models allow manual folding as well. This feature offers several conveniences, but used in winter, it often isn’t the best choice.
When drivers fold mirrors by hand, they must approach the vehicle and physically grip the mirror housing. Snow buildup can make this awkward, and winter residue, including salt or de-icing agents, can soil hands and clothing. Morning checks are also necessary to ensure the mirrors return to their driving position.
In certain vehicles, mirrors fold automatically when the central lock is used. In cold weather, this automatic action can become unreliable or slow.
Ice or sleet can freeze the protective caps on the mirrors, sticking them to the housing. The ice crust can impede the electric motor from functioning smoothly, potentially stressing the mechanism. For some cars, attempting to fold or unfold with ice present can even risk damage to the drive components.
Ice buildup may also nick the paint if the mirrors open with ice in the way. A layer of ice between the moving parts and the mounting area can create resistance that interferes with proper alignment and operation.
Overall, in winter it is often wiser to disable automatic folding of the mirrors if the feature is available. If it isn’t, drivers should minimize manual folding actions and perform them with care to avoid harm to the mirrors or the vehicle body.
