A practical winter checklist for tires, visibility, battery condition and emergency supplies—guided by your vehicle’s requirements and the conditions ahead.
Prepare before the first difficult morning
Ontario winter driving can bring rapidly changing visibility, temperature and road conditions. Preparation reduces avoidable surprises, but no equipment makes every journey safe. Check forecasts and road information, allow extra time and postpone travel when conditions warrant it.
Use the owner’s manual for tire sizes, fluid specifications, jump-starting procedures and vehicle-specific winter precautions. Electric and hybrid vehicles also have model-specific charging and range considerations.
Check tires and pressures
Choose tires suitable for the vehicle and expected conditions. If selecting winter tires, discuss a matching set and approved fitment with a qualified tire professional. Tire condition, tread and age matter as well as the label.
Check cold tire pressure against the vehicle placard or manual, not the maximum shown on the tire sidewall. Temperature changes can affect pressure. Inspect for damage and uneven wear, and investigate repeated pressure loss.
Make visibility a priority
Check wipers, washer operation, exterior lights and the heating/defrosting system before they are needed. Use washer fluid intended for the expected temperatures and the vehicle’s requirements.
Clear snow and ice from windows, mirrors, lights and the roof before setting off. Do not rely on a small cleared patch of windshield. Keep lights and sensors clean using the manufacturer’s guidance.
Review battery and fluid condition
Cold weather can reveal a weak starting battery. If starting has slowed or the battery’s history is uncertain, consider a condition check. Use the specified jump-start points and procedure; incorrect connections can cause injury or vehicle damage.
Coolant, engine oil and other fluids should meet the vehicle’s specification. Do not mix products based only on colour. A leak or repeated need for topping up deserves investigation.
Pack for delays and adjust the journey
An emergency-supplies starting point
Keep supplies suitable for the route and season in the vehicle. A starting point includes:
- Warm clothing and a blanket.
- A flashlight.
- A phone charging option.
- Basic emergency supplies, following official local guidance for a fuller kit.
Maintain extra following distance, reduce speed appropriately and use smooth inputs. Driver-assistance systems have limitations; snow-covered markings and sensors can affect their operation. Preparation supports careful decisions rather than replacing them.
Frequently asked questions
Should I use the pressure printed on the tire?
Use the vehicle’s recommended cold pressure from the placard or manual. The sidewall maximum is not normally the everyday target for the vehicle.
Do winter tires remove the need to slow down?
No. Grip remains limited by conditions. Adjust speed and following distance, and avoid travel when the conditions are beyond what is safe.
Can I choose coolant by its colour?
No. Follow the exact coolant specification and mixing guidance for the vehicle. Colour alone does not establish compatibility.
Plan ahead for the season
Ask about vehicle-specific checks and describe any starting, visibility or tire concerns before winter travel.
