Driving in Chicago during the winter can be tricky, no matter the Mercedes-Benz model that you drive. The freezing temperatures reduce battery capacity, affecting performance, while heavy snowfall makes the roads more slippery, increasing the risk of skidding.

Although the winter months bring unique challenges for Chicagoland drivers to contend with, there’s plenty you can do to prepare your vehicle for extreme weather. Our winter driving experts at Mercedes-Benz of Hoffman Estates have broken down some key steps you should take before the temperatures start to plummet and the first snowflakes start to fall.

Check Your Battery, Fluids, and Engine Health

Battery inspections are a crucial aspect of winterization. As the temperature drops, your battery has to produce more power to start your GLC-Class or E-Class sedan. However, batteries tend to weaken with age and typically need to be replaced after three or four years of use. That’s why it’s crucial to have your battery examined and tested by professional service technicians ahead of winter. Our Mercedes-Benz-certified service team can do that right here and let you know if it’s time to change yours.

Your fluids and engine components also require attention. Topping up your antifreeze prevents your cooling system from freezing over when the temperatures drop. You’ll also want to replenish your engine oil to help cope with the extra demands of cold weather and snowy-covered roads. Fresh engine oil reduces friction, allowing your engine to give its best performance when you need it the most.

When you book an appointment with us, our certified technicians will perform a comprehensive fluid check and replace your coolant fluid and engine oil with Mercedes-Benz-approved fluids if necessary. They will also install a winter-grade windshield washer fluid that won’t freeze at low temperatures. This will ensure your wiper blades provide the best visibility in heavy snowfall.

Install Proper Winter Tires and Inspect Brakes

Driving through Chicago during winter requires the right tires. And Mercedes-Benz winter tires are built to handle the cold weather and icy streets. Their rubber stays soft even when temperatures fall below freezing. This flexibility gives your tires the grip they need to maneuver through snow and slush. Their deep treads push away water and ice, allowing the tires to stay in contact with the road. This ensures smoother control when braking or turning in harsh conditions.

If you’re still driving on all-weather tires, now is the time to consider switching to winter tires. Our service center can help you get ready before winter hits. We install genuine Mercedes-Benz winter tires that are built for your exact model. Each set is tested to work seamlessly with your vehicle’s advanced safety systems like 4MATIC® all-wheel drive and the Electronic Stability Program (ESP®. You’ll feel the difference in traction, handling, and control when the streets get slippery.

Winter is also demanding on your brakes. The combination of low temperatures, salt, and moisture can cause brake pads to wear out a lot faster. A thorough inspection before the first heavy snowfall helps keep you safe. Our technicians will check the brake pads, rotors, and brake fluid levels carefully. If the pads are thin or the fluid is old, we’ll replace them right away.

Protect the Exterior with Detailing and Sealants

Chicago’s extreme winters can cause untold damage to your vehicle’s paint job. Exposure to snow, salt, and slush can eat away at your Mercedes-Benz’s polished finish. That’s why it’s important to get an exterior detailing service before heavy snowfall sets in.

When you bring your vehicle to Mercedes-Benz of Hoffman Estates for a detailing appointment, our service team will give it a thorough wash to remove salt and grime. Doing so will protect your vehicle’s paint from scratches. We will also repair any small chips or dents to minimize the risk of rust formation.

Finally, we will apply a quality paint sealant to your Mercedes-Benz’s exterior. Sealant creates a protective layer against road salt and ice. It also helps water bead off easily, reducing residue and buildup that may otherwise lead to rust formation.

How 4MATIC® and Safety Systems Help in Snow and Ice

Mercedes-Benz 4MATIC® is your perfect companion for winter driving. This sophisticated all-wheel drive system monitors road conditions and automatically adjusts torque delivery to all four wheels. It can detect when the front or rear wheels lose grip and immediately redirect power to the ones that still have traction. This functionality results in smoother handling and control on snow-covered roads.

What sets 4MATIC® apart is how seamlessly it works with your vehicle’s other systems. It’s linked to the Electronic Stability Program and Anti-lock Braking System, which monitor steering, throttle, and wheel speed hundreds of times per second. Together, they balance traction, prevent wheelspin, and help your Mercedes-Benz maintain grip through corners and sudden stops.

Mercedes-Benz also features plenty of driver assistance technologies to protect you and your car when driving in challenging winter conditions. Active Braking Assist helps bring you to a swift stop and avoid collisions. Meanwhile, the driver attention monitor tracks your attentiveness and will alert you when it’s best to take a break for your own safety during longer drives.

Mercedes-Benz’s adaptive cruise control is another technology that comes in handy during Chicago’s winters. It helps you maintain a safe distance from the motorists ahead, reducing the risk of collisions on slippery roads. Equally useful is pedestrian detection, which alerts you to people up ahead so you can slow down to prevent crashing into them.
