The recommended tire pressure for the Mercedes-Benz GLS 2020 is typically 36 PSI for the front tires and 39 PSI for the rear tires. However, you should always verify this information in your owner's manual or on the sticker inside the driver's side door jamb.
To pair your smartphone via Bluetooth, ensure Bluetooth is enabled on your phone. In the vehicle, go to the "Telephone" menu on the infotainment system, select "Connect Device", and choose "Search for Phones". Select your phone from the list and follow the prompts to complete pairing.
If the key fob battery is low, replace it with a new CR2032 battery. To replace, remove the mechanical key by pressing the release button, then use the key to open the battery compartment. Replace the old battery with the new one, ensuring the positive side faces up.
To engage the parking assist feature, press the parking assist button located on the center console. The system will scan for a suitable parking space. Once a space is found, follow the on-screen instructions to control the brake and gear while the vehicle steers automatically.
Use a soft, damp cloth to gently wipe the leather seats. Avoid using harsh chemicals or abrasive cleaners. For deeper cleaning, use a leather cleaner and conditioner specifically designed for automotive interiors, and follow the product instructions carefully.
A "Check Engine" light can be triggered by various issues including a loose fuel cap, faulty oxygen sensor, or engine misfire. It's recommended to use an OBD-II scanner to read the error codes or visit a certified Mercedes-Benz service center for a thorough diagnosis.
If the power liftgate is not working, you can manually open the tailgate by unlocking it using the key fob or the button on the driver's door panel. Then, lift the tailgate manually. If there's resistance, check for any obstructions or mechanical issues.
