Adapt your driving style accordingly. Have the spare tire replaced with a winter tire at the nearest authorized Mercedes-Benz Light Truck Center. G Winter tires with a tread depth under 1⁄6 in (4 mm) must be replaced. They are no longer suitable for winter operation. Block heater (Canada only) The engine is equipped with a block heater.
