To reset the maintenance light, turn the ignition to position 1. Use the steering wheel controls to navigate to the 'Trip' menu. Press and hold the phone button and then the 'OK' button until you enter the service menu. From there, select 'Full Service' and confirm the reset.
The recommended oil for the 2020 Mercedes-Benz E-Class Wagon is a fully synthetic 0W-40 or 5W-40 that meets the MB 229.5 or MB 229.51 specifications.
To pair your smartphone, enable Bluetooth on your device. On the vehicle's infotainment screen, navigate to 'Phone' and then 'Connect Device'. Select your phone from the available devices list and confirm the pairing code on both the phone and the vehicle screen.
If the air conditioning is not cooling, check if the A/C is turned on and set to the correct temperature. Ensure the cabin air filter is not clogged. If the issue persists, it could be a refrigerant leak or compressor issue, which would require a professional inspection.
To change a flat tire, locate the spare tire and jack in the trunk. Loosen the lug nuts slightly before jacking up the car. Raise the car with the jack, remove the lug nuts completely, and replace the flat tire with the spare. Tighten the lug nuts in a crisscross pattern before lowering the vehicle.
The recommended tire pressure is usually found on a sticker inside the driver's door jamb. For the 2020 E-Class Wagon, it is typically around 32 psi for the front tires and 35 psi for the rear tires. Always verify with the specific vehicle's sticker.
Updates for the navigation system can be performed by downloading the latest maps from the Mercedes-Benz website onto a USB drive. Insert the USB into the vehicle's port and follow the on-screen prompts to update the navigation system.
A check engine light can be triggered by various issues, from a loose gas cap to more serious engine problems. It's best to use an OBD-II scanner to diagnose the error code or take the vehicle to a qualified technician for a detailed inspection.
To improve fuel efficiency, ensure regular maintenance such as oil changes and air filter replacements. Maintain proper tire pressure and avoid aggressive driving habits. Consider using the ECO driving mode for optimized fuel consumption.
If the battery dies, you can jump-start the vehicle using jumper cables and another car. Ensure both cars are turned off, connect the positive cable to the positive terminal on both batteries, then connect the negative cable to the negative terminal on the working battery and a metal ground on the dead car. Start the working car, then attempt to start your E-Class Wagon.
