Why Winterize Your Subaru?

Winter weather in areas surrounding Sunset Hills, including Maplewood and Twin Oaks, can shift rapidly from mild to treacherous conditions. Snowfall, ice patches, and cold temperatures affect vehicle performance, especially in safety and traction. Winterizing your Subaru isn’t just about comfort—it’s a critical safety measure.

Missouri winters often bring temperatures dipping below freezing, which can impact tire grip, battery efficiency, and fluid viscosity. Preparing your Subaru ensures you maintain control on slick roads, prevent mechanical failures, and protect your family. Subaru’s renowned Symmetrical All-Wheel Drive (AWD) is a powerful asset, but it performs best when paired with winter-ready maintenance and driving practices.

Winterizing also extends your Subaru’s longevity by preventing damage caused by freezing fluids or cold starts. Whether you live in Webster Groves or commute through St Charles, this preparation supports reliable daily driving and adventurous weekend trips.

Tire Care and Winter Tires for Maximum Traction

Proper tires are the cornerstone of winter readiness. Your Subaru’s AWD system works by distributing power to all four wheels, but without good traction, even AWD can be challenged on ice and snow.

• Tread Depth and Tire Inspection: Check your current tires for a tread depth of at least 6/32 of an inch. Anything below 4/32 is insufficient for winter traction. Inspect for uneven wear or cracks that could worsen on cold roads.
• Switch to Winter Tires: Winter tires use specialized rubber compounds and tread designs that remain flexible in cold weather and grip ice and snow better than all-season tires. For residents in Oakville, Maryland Heights, or Concord, switching to winter tires before the first snow ensures safer commutes and better vehicle response.
• Tire Pressure: Cold weather reduces tire pressure. Maintain tire pressure between 32-35 psi, checking regularly as pressure dips can impair handling and increase wear.
• Additional Traction Aids: For extreme Missouri winters, consider tire chains or traction boards, especially if venturing off paved roads near Fenton or Valley Park.

Sunset Hills Subaru can inspect your tires and help you select the ideal winter tires, balancing safety and cost-effectiveness.

Battery, Fluids, and Antifreeze Essentials

Cold temperatures can strain your Subaru’s battery and vital fluids. Ensuring these systems are winter-ready is crucial.

• Battery Health: Batteries lose up to 50% of their starting power in cold temperatures. Have your battery tested to confirm it holds a strong charge. If your battery is older than three years or struggling, replacing it now avoids inconvenient breakdowns.
• Antifreeze/Coolant: Use Subaru-approved antifreeze. For most models after 2008, Subaru’s Super Long Life Blue Coolant is recommended, providing protection against freezing and corrosion for up to 60,000 miles. Older models may require the traditional Subaru Green Long Life Coolant. Using the correct antifreeze prevents engine freeze-ups and overheating.
• Do Not Use Regular or Aftermarket Coolants: Regular green antifreeze or aftermarket products like Dex-Cool can cause clogs or corrosion in Subaru engines. Always opt for genuine Subaru coolant available through our Parts Department.
• Windshield Washer Fluid: Use winter-grade washer fluid that won’t freeze, ensuring clear visibility during snow or sleet.
• Oil and Other Fluids: Ensure your oil is rated for colder temperatures (consult your Subaru owner’s manual). Check brake, transmission, and power steering fluid levels and condition.

Activating and Using Subaru’s X-MODE Snow Mode

Subaru’s X-MODE is designed to enhance your vehicle’s performance in snow, mud, and slippery conditions by optimizing throttle response, transmission behavior, and torque distribution.

• What X-MODE Does: It adjusts engine power delivery to prevent wheel spin, locks the AWD system for balanced torque distribution, and enhances Vehicle Dynamics Control (VDC) for stability. Hill Descent Control (HDC), part of X-MODE, automatically manages braking on steep declines.
• How to Activate:
  • Locate the X-MODE button on the center console or the X-MODE icon on your infotainment touchscreen.
  • Press the button or tap the icon to activate. On some models, you can select between “Snow/Dirt” or “Deep Snow/Mud” modes for tailored traction control.
  • The dashboard will display an indicator light confirming activation.
• Speed Limitations: X-MODE operates effectively at speeds below approximately 18-25 mph and disengages automatically above that range.
• Practical Use: Use X-MODE when navigating unplowed roads near Chesterfield or icy streets in Richmond Heights. It’s especially helpful when climbing steep driveways or during off-road excursions.

For a demonstration or assistance in using X-MODE on your specific Subaru model, visit our dealership or contact us at (314) 476-9638.

Driving Your Subaru Safely in Snow and Ice

Equipping your Subaru for winter is only part of the equation. Adapting your driving style to winter conditions is equally vital.

• Drive Slowly and Smoothly: Reduce speed significantly on snow or ice. Sudden acceleration, braking, or sharp turns can cause loss of control.
• Maintain Distance: Increase following distance to at least five to six seconds, allowing ample time to react.
• Avoid Abrupt Maneuvers: Brake gently before turns, then release the brake and steer smoothly.
• Counter-Steering: If your Subaru begins to slide, steer gently into the skid to regain control.
• Use Lower Gears: When driving manual transmission models, start in second gear to reduce torque and prevent wheel spin.
• Do Not Use Cruise Control: It’s unsafe on slippery surfaces, as it may cause unintended acceleration.
• Trust Symmetrical AWD: Subaru’s AWD system is always on, distributing power to wheels with traction, but it cannot defy physics—safe driving is always required.

Warming Up Your Subaru and Winter Maintenance Tips

Modern Subaru engines don’t require lengthy warm-ups, but a brief period improves comfort and system performance.

• Warm-Up Time: Typically, a 20 to 60-second warm-up is sufficient before driving. Avoid revving the engine; drive gently until your temperature gauge reaches normal operating levels.
• Regular Maintenance: Keep up with winter-specific maintenance, including checking wiper blades, battery, tire condition, and fluid levels.
• Pre-Winter Service: Visit Sunset Hills Subaru for a winter check-up, including a battery test, fluid flush, and visual inspection of braking and suspension components.
• Use Genuine Parts: For any replacement parts, trust our Find Subaru Parts portal to ensure quality and compatibility.
