The 2015 Mercedes-Benz C300 4Matic is a moderately difficult vehicle to maintain. The oil drain plug is behind a large panel underneath. The panel is difficult to pull down, as you must work upside-down underneath. To remove the front wiper blade, you must use the wiper stalk to raise it and a tool to remove it. Other models will not require the use of tools to remove a blade. One of the cabin air filters is difficult to reach underneath the glove box. You must use multiple tools to remove multiple large panels.
There are a few easier aspects to the 2015 Mercedes-Benz C300 4Matic. The reverse light is easy to reach. Once you pull off a cover in the rear of the vehicle you can quickly reach the bulb assembly. The engine coolant reservoir is in the front of the engine bay. You won’t have to reach far to add fluid or check the fluid levels. The child seats are easy to connect. The hooks you latch onto have indicators above them, making it easy to spot the hooks.
