Some things you may usually leave in your car or truck could be damaged it the current freezing temperatures we are experiencing in the Valley.

21 News has put together a list of items you should bring inside your home until the chilly weather passes.


Cell phones

According to Apple Support, iPhones, iPads, and the iPod touch should be stored within acceptable operating temperatures Use iOS devices where the ambient temperature is between 32º to 95º F. Low- or high-temperature conditions might cause the device to change its behavior to regulate its temperature. Using an iOS device in very cold conditions outside of its operating range might temporarily shorten battery life and could cause the device to turn off. Battery life will return to normal when you bring the device back to higher ambient temperatures.

Store the device where the temperature is between -20º and 45º C (-4º to 113º F). Don’t leave the device in your car, because temperatures in parked cars can exceed this range.


Electronic devices suffer from temperature extremes according to Hampshire College. Liquid Crystal Displays (LCDs) of laptops, phones, and PDAs can freeze. Laptops have been designed to work within a safe temperature range, normally 50 to 95 degrees F. This range refers both to optimal usage temperature of the outside environment and the temperature the laptop should be warmed to before using.

Never leave a laptop, or other devices, even in a well-padded and insulated case, in the trunk of a vehicle in cold or hot weather for long periods of time. The device could freeze and you lose all data contained in it. Heat may also damage components.

Once you bring a laptop in from the cold (or heat), allow it to return to room temperature before booting. "Ruggedized" laptops are designed to work under extreme weather conditions.

Do not boot up an LCD display device if you suspect the display is frozen. Don't use heating pads or other external sources of heat to warm up or thaw the display. Allow it to warm on its own.

Not enough gasoline

Not leaving enough gas in your vehicle can be hazardous to the health of your car, truck, or SUV. AAA advises drivers to keep their gas tanks at least half full. In addition to having enough fuel when needed, keeping the tank half full helps avoid fuel line freeze up.


Cold temperatures can change the fit of your glasses or sunglasses according to Eye2Eye Optometry. Colder temperatures, especially below freezing, the material contracts, and that change can cause tiny cracks to form.


Liquids expand when they freeze and in some low temperatures, the containers may burst, leaving a slushy mess. SNV Plastics says it takes a temperature lower than 32 degrees to freeze Coca Cola because of the extra sugar and carbonation. Frozen Coke may stay slush until it is opened and then it may freeze solid when it is opened and the carbonation is released.


Canned Goods

The USDA says cans frozen accidentally, such as those left in a car or basement in sub-zero temperatures, can present health problems. If the cans are merely swollen — and you are sure the swelling was caused by freezing — the cans may still be usable. Let the can thaw in the refrigerator before opening. If the product doesn't look and/or smell normal, throw it out. Do not taste it! If the seams have rusted or burst, throw the cans out immediately, wrapping the burst can in plastic and disposing of the food where no one, including animals, can get it.

The USDA also says shell eggs should not be frozen. If an egg accidentally freezes and the shell cracked during freezing, discard the egg. Keep any uncracked eggs frozen until needed; then thaw in the refrigerator. These can be hard cooked successfully but other uses may be limited. That's because freezing causes the yolk to become thick and syrupy so it will not flow like an unfrozen yolk or blend very well with the egg white or other ingredients.


The FDA says don't use insulin that has been frozen. Insulin loses some effectiveness when exposed to extreme temperatures.

Musical Instruments

Wooden instruments are particularly vulnerable to cold weather according to the Grace Music School.

If your wooden instrument, such as a violin or guitar, is exposed to too cold of weather, the material can shrink or expand, causing the wood to potentially crack or the glue joints to break.

Cold weather can also cause harmful changes in humidity levels. If your instrument is exposed to too much moisture, it could develop condensation which could lead to mold growth. This can particularly be an issue with instruments that use reeds.

Besides just the frame, cold weather can affect the moving parts of your instruments. This can not only make your instrument hard to tune, but also make it sound sluggish. Typically, the larger an instrument is, the more noticeable the sound change is.


It's common sense not to leave people or pets in cars during extremely cold weather. Children and the elderly are susceptible to frostbite and hypothermia.

Leaving pets in your vehicle in the cold can be just as dangerous as leaving them in a car or truck during the summer. The interior temperature of a car can drop quickly in very cold temperatures.
