In addition to annual maintenance, here are some tips to winterize your car:
Test your battery; battery power drops as the temperature drops
Make sure the cooling system is in good working order
Have winter tires with a deeper, more flexible tread put on your car
If using all-season tires, check the tread on your tires and replace if less than 2/32 of an inch
Check the tire pressure; tire pressure drops as the temperature drops
Check your wiper blades and replace if needed
Add wiper fluid rated for -30 degrees
Keep your gas tank at least half full to avoid gas line freeze
Remember to keep your car’s emergency preparedness kit fully stocked, too.
Before You Start Out
Clean your car’s external camera lenses and side view mirrors so you’ll be able to see what’s around you
Remove dirt, ice and snow from sensors to allow the assistive-driving features like automatic emergency braking to work
In frigid weather, you may want to warm up the car before you drive it
To prevent carbon monoxide poisoning, never leave a vehicle running in your garage – even with the garage door up
If the forecast looks iffy, wait out the storm if possible; if you must travel, share your travel plans and route with someone before you leave
How to Avoid a Crash
Avoid using cruise control in wintry conditions
Steer in the direction of a skid, so when your wheels regain traction, you don’t have to overcorrect to stay in your lane
Accelerate and decelerate slowly
Increase following distance to 8 to 10 seconds
If possible, don't stop when going uphill
If visibility is severely limited due to a whiteout, pull off the road to a safe place and do not drive until conditions improve. Avoid pulling off onto the shoulder unless it is an absolute emergency. Limited visibility means other vehicles can’t see yours on the shoulder.
Know Your Car’s Capabilities
Traction control is now standard on most new vehicles. This function helps your vehicle gain traction on snowy, icy or wet surfaces, particularly when accelerating from a stopped or slowed position, or when trying to make it up a slippery hill.
Anti-lock braking system (ABS) helps you steer in emergencies by restoring traction to your tires and is standard on most new vehicles as well. ABS may vibrate or pulse when engaged. This is normal. Continue to press and hold pressure to the brake pedal.
Remember, you are your car's best safety feature. Take precautions to ensure you arrive safely at your destination. If you become stranded in an unfamiliar area, do not leave your car. Light flares in front and behind the car and make sure the exhaust pipe is not blocked by snow, mud or objects.
