Your Subaru handles a lot, but the first icy morning on Route 9 will test more than its drivetrain. These winter prep tips for drivers in MA focus on what to do now, before the first storm, so your commute stays predictable. You can schedule service at MetroWest Subaru in Natick.
Why Massachusetts Winters Are Tough on Your Subaru
Ice and swinging temperatures make familiar commutes unpredictable. If you drive from Wellesley to Natick or up I-95 from Norwood, small problems show up fast in the cold. Dead batteries, tire problems, and crashes or slide-offs are the most common winter roadside issues, and early attention lowers your risk of all three.
What Ice, Nor'easters and Road Salt Do to Your Vehicle on Route 9, the Mass Pike and I-95
Snow and ice reduce grip, while slush hides changes in the road surface. Road salt can cause corrosion or damage, which is another reason to inspect and clean your vehicle through winter. MassDOT advises extra caution on bridges, overpasses, and shady roads in freezing conditions because they ice first. That matters on Route 9 and the Mass Pike (I-90), where overpasses and shaded ramps come up constantly.
What Symmetrical All-Wheel Drive Does and Doesn't Do in Winter
Symmetrical All-Wheel Drive is always active, and nearly every Subaru has it as standard, though a few models aren't AWD. It helps you get moving, stay stable, and hold your line through turns. On ice or packed snow, though, it does little to help you stop, and it can't add grip your tires don't have. Tires have the biggest effect on acceleration, turning, and stopping.
Picture a scenario we worry about. You exit the Mass Pike on a shaded off-ramp with AWD and all-season tires. You pull away confidently, then brake for the stop sign and the car keeps sliding, because the tires have little grip on the ice.
On models with Dual-Function X-MODE, you can choose Snow/Dirt or Deep Snow/Mud. X-MODE deactivates above 18 mph and isn't meant for normal highway driving.
Switch to Winter Tires for Maximum Traction
Winter tires stay more flexible in the cold and grip snow and ice better than typical all-season tires. Kelley Blue Book cites research finding braking distances up to 30% shorter with winter tires than with all-season tires. AWD can't replace that tire-to-road traction. Our technicians handle winter tire swap-outs and tire installation, so you can book your swap early.
All-Season vs. Winter Tires on a Subaru
All-season and summer compounds start to harden around 44°F. Winter tires use softer rubber and a different tread pattern with more sipes. They do wear faster on dry pavement, which is the tradeoff.
| Tire Type | Cold-Weather Grip | Snow/Ice Braking | Best Use | Typical Swap Timing |
|---|---|---|---|---|
| All-season | Compound hardens near 44°F | Longer stopping distances | Mild weather | Fall removal |
| Winter | Softer rubber stays flexible | Up to 30% shorter braking than all-season | Cold, snow, and ice | Daytime highs consistently below about 45°F |
When to Swap Tires and Why All Four Should Match
Swap when daytime highs stay consistently below about 45°F, and swap back in spring. Rotate winter tires at your regular Subaru service, typically every 6,000 miles.
On an AWD Subaru, use four matching tires of the same size and category. Don't mix winter with all-season. A Subaru service professional can advise whether one, two, or all four need replacing.
How to Check Tread Depth and Tire Pressure in Cold Weather
Try the quarter test. Insert a quarter head-down into the tread.
-
If the tread covers part of Washington's head, you have at least 4/32 inch left, but keep watching it.
-
If you can see all of Washington's head, you have less than 4/32 inch, and it's time to replace the tires.
At least 4/32 inch of tread is recommended for winter driving, since worn tires make it harder to stop on slick roads.
Pressure drops about 1 psi per 10°F. Check it when the tires are cold, and go by the number on the driver's door-jamb placard or in the owner's manual rather than the sidewall maximum. If your TPMS light comes on during a cold snap, take it seriously.
Test Your Battery and Check Antifreeze Before the Cold Hits
Cold weather exposes weak batteries and tired fluids. Testing now costs you far less time than a dead battery at a Route 9 light.
Battery Health and Cold-Weather Starting Power
Cold slows the battery's chemical reactions and reduces power. At freezing, even a fully charged battery delivers only about two-thirds of its rated capacity. Battery life is typically three to five years, so have yours tested before winter, especially if it needed a jump in summer.
Appointment-free Express Service covers battery testing and replacement. Check our current service specials before you visit.
Antifreeze, Oil and Brake Checks for Salt and Freezing Temps
Test antifreeze protection annually with an inexpensive tester. Mass.gov's winter checklist covers brakes, proper-grade oil, the cooling system, antifreeze, fluids, and exhaust. A full gas tank may also prevent condensation.
Have the brakes inspected for wear before icy driving, and look for corrosion from salted roads. This guidance is general. Consult your Subaru owner's manual or our service team for model-specific requirements, including oil grade and coolant type.
Improve Visibility With Wipers, Washer Fluid and Lights
Good visibility helps you see hazards and helps others see you.
-
Check the wipers and defrosters, and replace worn blades.
-
Top off the washer reservoir with a winter fluid that contains de-icer.
-
Check headlights, brake lights, turn signals, and flashers.
Clear snow and ice from your windows, lights, hood, and roof, and wipe off the sensors too. Keep the windshield clear in front of your EyeSight cameras so they perform at their best. Massachusetts requires you to clear snow and ice from your vehicle, and clearing the roof matters too, since sliding snow can hit the cars behind you.
Pack a Winter Emergency Kit and Follow Safe Driving Habits
A kit should cover clearing snow, staying warm, signaling for help, and charging your phone. Check it periodically so supplies stay usable. If you're stranded in severe weather, call for help and generally stay with the vehicle, unless staying there is immediately dangerous.
Emergency Kit Essentials for Commuters
-
Ice scraper and snow brush
-
Flashlight
-
Charged phone and car charger
-
Jumper cables
-
Blankets and extra clothes
-
High-calorie food and water
-
First aid kit
-
Shovel

-
Tow rope, road flares or reflectors, and basic tools
-
Fire extinguisher
Driving Tips for Ice, Skids and Getting Stuck
Slow down and increase your following distance. Posted limits are for dry pavement, so adjust. Give plows room and leave cruise control off. Skip unnecessary lane changes. Call 511 for road conditions.
Black ice can look like shiny wet road. Brake in advance and ease off the accelerator. If you skid, ease off the throttle, steer where you want to go, and brake gently.
If you get stuck:
-
Check the wheel wells for packed snow.
-
Straighten the wheels.
-
Put sand or cat litter under the drive wheels.
-
Accelerate gently and avoid spinning. Rocking the car can help.
-
Keep the tailpipe clear if you're idling in snow.
