Driving with summer tires
At temperatures below 45 °F (+7 °C), the elasticity of summer tires and therefore also traction and braking capability are reduced considerably — equip your vehicle with M+S tires. Using summer tires at very cold temperatures could cause tears to form, thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility for this type of damage.
