Warm and safe vehicles are a must in sub-zero temperatures.

On Monday, the dipping temperatures resulted in CAA Manitoba, many people's go-to for dead car batteries, experienced such high call volumes that they suspended at home service calls, prioritizing unsafe situations.

To keep vehicles running, many Manitobans will warm up their vehicles. The Winnipeg Police Service says to never leave a running vehicle unattended, especially with children or pets inside.

"Over the past few months, we have all enjoyed the luxury of above seasonal temperatures. Unfortunately, the more typical cold weather cycle is again upon us."

They say in January, of the 175 reported stolen vehicles, 71 of those were running with the keys inside and 29 had the keys left inside the vehicle.

They say running vehicles are easy targets and to never leave the vehicle unattended. They suggest installing command start.

Many people plug their vehicles' block heater in to protect it. The Winnipeg Fire Paramedic Service (WFPS) says to never plug vehicles in when they are inside.

“It doesn't get cold enough to plug in and unfortunately every winter the WFPS responds to calls for fires originating in the vehicle in an attached garage,” Leigh Gruener, WFPS Public Education Officer, says. "There really is no need to plug it in inside a sheltered building."

Before plugging in, she says to check the chord for damage.

Super Lube Auto Centres says "A stalled car in frigid temperatures could be life-threatening to you and your passengers. It can even endanger other drivers who are forced to maneuver around you."

They are asking drivers to use winter oil in their vehicles and to warm up vehicles for one to two minutes before driving.
