Winter Car Care Checklist for Chicago Drivers
Cold, snow and salt are hard on a car. This checklist pulls together Toyota's own pre-winter steps from the RAV4 Owner's Manual, the National Weather Service's vehicle and storm-kit advice, and FuelEconomy.gov's data on cold-weather mileage, all read October 27, 2026, with what our service department on North Western Avenue can check for you.
3 fluidsoil, coolant and washer fluid matched to the cold
Every 2 weeksor at least monthly: Toyota tire pressure checks
About 15%lower city mpg at 20°F (FuelEconomy.gov)

How do I get my car ready for winter?
Toyota's RAV4 Owner's Manual lists four pre-winter steps: use engine oil, engine coolant and washer fluid appropriate to the outside temperatures; have a service technician inspect the battery; fit four snow tires or buy tire chains for the front tires; and keep all tires the same size and brand. Add regular tire pressure checks, good wiper blades and a winter storm kit in the car.
Winter car care checklist
| Check | What to do | Source |
|---|---|---|
| Engine oil | Use oil appropriate to the outside temperatures. Toyota calls SAE 0W-16 the best choice for good fuel economy and good starting in cold weather for the RAV4; follow your own owner's manual. | Toyota RAV4 Owner's Manual |
| Engine coolant | Use coolant appropriate to the outside temperatures. | Toyota RAV4 Owner's Manual |
| Washer fluid | Use washer fluid appropriate to the outside temperatures, and keep fluid levels full before a longer trip. | Toyota; National Weather Service |
| Battery | Have a service technician inspect the condition of the battery. Cold weather reduces battery performance. | Toyota; FuelEconomy.gov |
| Tires | Fit four snow tires, or buy tire chains for the front tires. Keep all tires the same size and brand. | Toyota RAV4 Owner's Manual |
| Tire pressure | Check every two weeks, or at least once a month, with the tires cold. | Toyota RAV4 Owner's Manual |
| Lights, heater and wipers | Make sure they are in proper condition before you leave, especially before a longer trip. | National Weather Service |
| Fuel | Keep the gas tank near full to avoid ice in the tank and fuel lines. | National Weather Service |
Toyota steps are from the RAV4 Owner's Manual (OM0R024U), Winter driving tips; your model's manual is the final word on fluids and tires.
Snow tires, chains and tire pressure
The RAV4 Owner's Manual is specific about snow tires: use the specified size, keep the recommended air pressure, put snow tires on all wheels rather than just some, and do not drive over 75 mph on them, whatever type they are.
Chains are a different case. On the RAV4 they go on the front tires only, and the manual says chains cannot be mounted on vehicles with 235/55R19 tires; snow tires should be used instead. With chains fitted, do not exceed the chain's speed limit or 30 mph, whichever is lower. Chain rules vary by location and road type, so check local regulations first.
Cold air lowers tire pressure. FuelEconomy.gov notes that tire pressure decreases in colder temperatures, which increases rolling resistance. Toyota says to check pressure every two weeks, or at least once a month, and to make sure the tires are cold before adjusting it. If your tire pressure warning light comes on, see our Toyota tire pressure light guide.
What cold weather does to your car
FuelEconomy.gov explains why mileage and performance drop in winter:
Cold oil and fluids
Engine and transmission friction increases because of cold engine oil and other drive-line fluids.
Longer warm-up
The engine takes longer to reach its most efficient temperature, which hurts short trips most.
Weaker battery
Battery performance decreases in the cold, making it harder for the alternator to keep it charged. On hybrids this also affects regenerative braking.
Hybrids lose more
Hybrid fuel economy typically drops 20% to 40% in city driving and 25% to 45% on short trips in the cold. See our Toyota hybrid battery guide.
Figures from FuelEconomy.gov (U.S. Department of Energy and EPA), Fuel Economy in Cold Weather, read October 27, 2026. Effects vary by vehicle model.
Before and during a winter drive
From Toyota's winter tips: do not force open a frozen window or move a frozen wiper. Pour warm water over the frozen area to melt the ice and wipe the water away right away so it does not refreeze. Clear snow from the air inlet vents in front of the windshield so the climate control fan works, and remove ice or snow from the exterior lights, roof, chassis, around the tires and on the brakes.
The National Weather Service adds: make sure the vehicle is completely clear of ice and snow before the trip, because flying snow from cars causes accidents. Slow down, since roads that only look wet can still be slick. If you begin to skid, ease off the gas and turn the wheels in the direction you want the front of the car to go; with anti-lock brakes, apply steady pressure and never pump the brake pedal.
To save fuel, FuelEconomy.gov suggests parking in a warmer place such as a garage, combining trips so you drive less often with a cold engine, and keeping idling to a minimum: most manufacturers recommend driving off gently after about 30 seconds.
Pack a winter storm kit
The National Weather Service recommends a Winter Storm Survival Kit in the vehicle. Its list includes:
Power and light
A mobile phone with charger and batteries, and a flashlight with extra batteries.
Food and warmth
High-calorie, non-perishable food and extra clothing to keep dry.
Traction and visibility
A sack of sand or cat litter for traction, and a windshield scraper and brush.
Getting found
A compass and road maps, rather than relying only on a phone with limited battery life.
From the National Weather Service, Prepare! Don't Let a Winter Storm Take You by Surprise, read October 27, 2026. The full NWS list has more items.
If you are stranded in a storm
The National Weather Service's advice if your car gets stuck during a storm:
- Stay with the vehicle. If you leave it, you will become disoriented quickly in wind-driven snow and cold.
- Run the motor about 10 minutes each hour for heat, and open a window a little for fresh air while it runs.
- Clear snow from the exhaust pipe to avoid carbon monoxide poisoning.
- Turn on the dome light at night when the engine is running, and tie a bright cloth to the antenna or door.
- After the snow stops falling, raise the hood to show you need help.
Before you set out in bad weather, the NWS also suggests letting someone know your route and timetable.

Winter car care FAQ
What should I check on my car before a Chicago winter?
Toyota's RAV4 Owner's Manual lists the pre-winter basics: engine oil, engine coolant and washer fluid suited to the outside temperatures, a battery inspection by a service technician, and four snow tires or a set of tire chains for the front tires. The National Weather Service adds full fluid levels and working lights, heater and wipers before a longer winter trip.
Why does my tire pressure drop when it gets cold?
FuelEconomy.gov notes that tire pressure decreases in colder temperatures, which increases rolling resistance. Toyota's RAV4 Owner's Manual says to check tire inflation pressure every two weeks, or at least once a month, and to make sure the tires are cold before adjusting pressure.
Should I warm up my car before driving in winter?
FuelEconomy.gov says idling gets 0 miles per gallon and that most manufacturers recommend driving off gently after about 30 seconds, because the engine warms up faster when driven. Clear all ice and snow from the vehicle before you go, as the National Weather Service advises.
How much does cold weather cut gas mileage?
FuelEconomy.gov says a conventional gasoline car's city mileage is roughly 15% lower at 20°F than at 77°F, and can drop as much as 24% on short 3- to 4-mile trips. Hybrids typically lose more, about 30% to 34% under the same conditions.
What should I keep in my car for a winter storm?
The National Weather Service's winter storm survival kit includes a mobile phone, charger and batteries; a flashlight with extra batteries; high-calorie, non-perishable food; extra clothing; a sack of sand or cat litter for traction; a windshield scraper and brush; and a compass and road maps.
