How to Care for a Hybrid Car in Winter

Hybrid cars that combine a petrol engine (ICE) and an electric power unit require special attention in winter. Low temperatures affect not only traditional components but also the most expensive part — the high-voltage battery (HVB). Proper maintenance and understanding of the hybrid system’s operation during the cold season help preserve its lifespan, ensure quick starts, and minimize fuel consumption. To make your car look more stylish and expressive, we recommend using tuning accessories, which are widely available in our product range.

Battery care

In winter, the driver may notice a reduction in electric-only range:

• Battery preheating: Many hybrids, especially plug-in hybrids (PHEV), have battery heating systems. Whenever possible, charge the car shortly before driving to activate the heater and start with a warm HVB.
• Warm storage: If possible, park the hybrid in a garage or underground parking. This slows down charge loss and speeds up morning warm-up.
• Charge control: Avoid leaving the HVB fully discharged for long periods.

Hybrids have a weak point — the small 12V battery: It can discharge faster in winter.

Engine operation and fluids

In winter, the ICE in a hybrid runs more often than in summer because it performs a dual function — propulsion and cabin heating.

• Engine oil: It is crucial to use fresh, low-viscosity oil (0W or 5W) according to the manufacturer’s recommendations. This ensures quick lubrication during frequent cold starts.
• Cooling system: Check the antifreeze concentration. The ICE will start more often to generate cabin heat, so a properly functioning cooling system is essential.
• Fuel tank: Try to keep the tank more than half full. This reduces condensation inside the tank, which can freeze and damage the fuel system.

Conclusion: The key to winter hybrid maintenance is minimizing long idle periods of the battery in the cold, warming it up before load, and keeping the ICE in perfect condition for frequent starts.
