Mercedes B 170 Workshop Manuals and Repair Manuals

To change the oil in a Mercedes B 170, first, locate the oil drain plug underneath the engine and remove it using a wrench. Allow the old oil to drain completely before replacing the drain plug. Next, remove the old oil filter and replace it with a new one. Finally, pour the recommended amount and type of fresh oil into the oil filler cap, and ensure it is at the correct level using the dipstick.

To check the engine coolant level in a Mercedes B 170, park the vehicle on a level surface and allow the engine to cool down. Open the hood and locate the coolant reservoir, which is usually a translucent plastic tank. The coolant level should be between the minimum and maximum marks on the side of the reservoir. If the level is low, add a mixture of equal parts coolant and distilled water to bring it to the recommended level. Avoid opening the coolant reservoir cap when the engine is hot to prevent injury.

To check the transmission fluid level in a Mercedes B 170, start the engine and allow it to reach normal operating temperature. Park the vehicle on level ground and engage the parking brake. Locate the transmission dipstick, usually near the back of the engine compartment, and pull it out. Wipe the dipstick clean, reinsert it fully, and then withdraw it again. The fluid level should be between the two designated marks on the dipstick. If it is low, add the recommended transmission fluid through the dipstick tube.

To jump-start a Mercedes B 170, park a working vehicle with a fully charged battery close to the one requiring a jump-start. Turn off the ignition in both vehicles. Connect one end of the positive (red) jumper cable to the positive terminal of the dead battery and the other end to the positive terminal of the charged battery. Connect one end of the negative (black) jumper cable to the negative terminal of the charged battery and the other end to a grounded metal surface on the vehicle with the dead battery, away from the battery itself. Start the working vehicle and let it run for a few minutes, then attempt to start the vehicle with the dead battery. Once started, remove the jumper cables in reverse order.

To replace a brake light bulb in a Mercedes B 170, open the trunk or tailgate and locate the access panel behind the brake light assembly. Remove the panel by unscrewing or unclipping it. Disconnect the electrical connector from the bulb socket and remove the bulb by turning it counterclockwise. Insert the new bulb by turning it clockwise until it is securely in place. Reconnect the electrical connector, replace the access panel, and test the brake light before closing the trunk or tailgate.

To replace a headlight bulb in a Mercedes B 170, first, ensure the vehicle's engine is off and the headlights are switched off. Open the hood and locate the back of the headlight assembly. Disconnect the electrical connector from the bulb, then remove the retaining clip or screws holding the bulb in place. Gently remove the old bulb and insert the new bulb, securing it with the retaining clip or screws. Reconnect the electrical connector and test the new bulb before closing the hood.

To replace the battery in a Mercedes B 170, first, ensure the engine and all electrical components are turned off. Locate the battery, usually under the hood or in the trunk, and remove the negative (black) cable from the battery terminal using a wrench or socket. Repeat this step for the positive (red) cable. Remove any battery hold-down brackets or clamps, then carefully lift the old battery out of its tray. Place the new battery in the tray, ensuring it is securely positioned. Reattach the positive cable followed by the negative cable, and tighten the connections.

To replace the cabin air filter in a Mercedes B 170, locate the cabin air filter housing, which is usually located behind the glove compartment or under the dashboard. Open the housing and remove the old filter, taking note of its orientation. Clean the filter housing if necessary, then install the new cabin air filter in the correct orientation. Close the housing and ensure it is securely fastened. Regularly replacing the cabin air filter helps maintain clean air inside the vehicle.

To replace the windshield wipers in a Mercedes B 170, lift the wiper arm away from the windshield and locate the release tab or button. Press or slide the release mechanism, depending on the wiper design, and slide the old wiper blade off the wiper arm. Align the new wiper blade with the arm and slide it on until it clicks into place. Gently lower the wiper arm back onto the windshield. It is recommended to replace both wiper blades at the same time for optimal performance.

To reset the maintenance light in a Mercedes B 170, insert the key into the ignition and turn it to the "on" position without starting the engine. Press and hold the reset button located on the instrument cluster until the maintenance light starts flashing. Release the button and turn off the ignition. Start the engine, and the maintenance light should be reset.

The air filter in a Mercedes B 170 should be replaced approximately every 30,000 miles (48,000 kilometers) or as recommended by the vehicle manufacturer. However, it is recommended to inspect the air filter regularly and replace it if it appears dirty or clogged. A clean air filter is crucial for proper engine performance and fuel efficiency.

The recommended tire pressure for a Mercedes B 170 can usually be found on a sticker located on the driver's side door jamb or in the vehicle's owner's manual. It is important to adhere to the recommended tire pressure, as underinflated or overinflated tires can lead to poor handling, decreased fuel efficiency, and increased tire wear. Regularly check the tire pressure and adjust it as needed to ensure optimal performance and safety.

In a Mercedes B 170, it is recommended to use a high-quality, ethylene glycol-based coolant that meets the specifications of the vehicle's manufacturer. This coolant should have a mixture of 50% coolant and 50% distilled water. It is essential to avoid using tap water as it may contain minerals that can cause corrosion or damage to the cooling system.
