The recommended oil for the 2018 Mercedes-Benz GLA is synthetic oil with a viscosity of 0W-40, meeting the MB 229.5 specification. Always consult the owner's manual or a certified dealer for confirmation.
To pair your phone, ensure Bluetooth is enabled on your device. On the vehicle's infotainment system, select 'Telephone', then 'Connect Device'. Choose 'Search for Phones' and select your phone from the list. Enter the passkey if prompted.
If the key fob is not working, you can manually open the trunk by using the physical key inside the key fob. Insert it into the lock cylinder located on the driver's side door to gain access to the interior and then use the trunk release lever.
The recommended tire pressure for the 2018 Mercedes-Benz GLA is typically 32 psi for both front and rear tires. However, it's best to check the sticker on the driver's side door jamb for the most accurate information.
To replace the key fob battery, press the small silver release button to remove the mechanical key. Use the key to open the battery compartment. Remove the old battery and insert a new CR2032 battery with the positive side facing up.
If the battery is fine but the car won't start, check the fuses and relays related to the ignition system. Ensure the gear shift is in 'Park' or 'Neutral'. If the issue persists, it may require professional diagnostics.
To change the cabin air filter, locate the filter housing under the glove compartment. Remove the cover by releasing the clips, then slide out the old filter. Insert the new filter in the same orientation and reattach the cover.
Common causes include a loose gas cap, faulty oxygen sensor, issues with the catalytic converter, or problems with the mass airflow sensor. A diagnostic scanner can provide specific error codes for troubleshooting.
To update the navigation system, purchase the latest map update from the Mercedes-Benz website or a dealership. Insert the update USB drive into the vehicle's USB port and follow the on-screen instructions to complete the installation.
