This is how to make the car winter-ready.

Frost, snow and road salt put drivers and vehicles to the test year after year. To ensure the vehicle makes it reliably through the winter, important components should be checked early. Automotive expert Christopher Lang from the workshop chain ATU explains what drivers should pay attention to now—and offers practical tips.

A taxi should be carefully maintained. And of course most taxi drivers know how to make their vehicle winter-ready. Nevertheless, a refresher can’t hurt.

1. Check the battery – most common cause of breakdowns in winter

Cold takes a particular toll on the car battery. Even at temperatures around the freezing point, its performance declines noticeably.

“Starting problems are among the most frequent causes of breakdowns in winter,” explains Christopher Lang of ATU. “The condition of the battery should be checked regularly. If you already have a weak battery, you should have it checked immediately and replaced if necessary—especially if it is older than four years.”

A free battery check at the workshop can help avoid costly tow charges.

2. Install winter tires in good time

Winter or all-season tires are mandatory in Germany in conditions of slick, snowy or icy roads. They offer not only better grip but also significantly shorter braking distances.

"Many drivers wait too long to change their tires," warns Christopher Lang. "Now in November it's high time for the switch. It's best to follow the 'O to O' rule—October to Easter."

Don't forget: Also check the tire pressure and tread depth. Legally, 1.6 millimeters are required, but for optimal safety a tread depth of at least 4 millimeters is recommended.

3. Check antifreeze protection in the radiator and in the windshield washer system

Too little antifreeze protection in the radiator can quickly lead to costly engine damage. Equally important is antifreeze protection in the windshield washer system, to maintain a clear view even at subzero temperatures.

"Drivers should have the antifreeze protection checked regularly and refilled in time," says expert Lang. "Modern testing devices show exactly whether sufficient antifreeze protection is present."

4. Check wiper blades and lighting

Worn wiper blades or defective light bulbs are a real safety risk in winter.

"If the wipers smear or leave streaks, that's a clear sign to replace them," explains Lang. "In addition, one should regularly clean the headlights in particular— road salt and slush quickly reduce the light output."

5. Maintain rubber seals and door locks

Frost often brings frozen doors and seals. In the worst case, the doors may no longer open or the rubber seals may be damaged. With specialized care products such as silicone spray or rubber care sticks, the seals can be pre-treated. Frozen door locks should be treated with a special de-icer spray.

“Many people forget to store the de-icer outside the car – in an emergency you’ll still be standing outside,” notes Christopher Lang with a wry smile.

6. Do not forget winter emergency equipment

An ice scraper, gloves, a blanket, a flashlight, and windshield frost protection fluid for refilling belong in every car in winter. An additional windshield de-icer spray and a charging cable for your cell phone can also be helpful in an emergency.

Conclusion

If you prepare your car for winter in good time, you will drive more safely, avoid breakdown stress, and extend the lifespan of important vehicle components.

“A short visit to the workshop can prevent many problems in winter,” summarizes expert Christopher Lang. “Safety begins with preparation – and that should be done now.”
