The recommended tire pressure is usually around 36 PSI for both front and rear tires, but you should check the driver's side door jamb for the exact specifications.

Possible causes include low refrigerant levels, a malfunctioning compressor, or a clogged cabin air filter. It's advisable to have a certified technician diagnose the issue.

Use synthetic oil that meets Mercedes-Benz specification MB 229.5 or MB 229.51. Refer to your owner's manual for the recommended viscosity grade.
First, replace the key fob battery. If the problem persists, try re-syncing the key fob or consult a Mercedes-Benz dealership for further assistance.
Ensure the car is on a flat surface and apply the parking brake. Use the provided jack and wrench to lift the car and remove the flat tire. Replace it with the spare, ensuring all lug nuts are securely fastened.
Maintain proper tire pressure, perform regular maintenance such as oil changes and air filter replacements, and avoid aggressive driving habits to enhance fuel efficiency.
Check for any loose gas caps, as this can trigger the light. If the issue persists, have the vehicle diagnosed with an OBD-II scanner to identify any underlying problems.
