To connect your smartphone via Bluetooth, first ensure that Bluetooth is enabled on your phone. Then, in the Elantra, go to the 'Setup' menu on your touchscreen, select 'Bluetooth', and then 'Pair New Device'. Follow the prompts to complete the pairing process.
Hyundai recommends servicing your Elantra every 7,500 miles or 12 months, whichever comes first. This includes oil and filter changes, tire rotation, and multi-point inspections. More extensive services are recommended at 15,000 and 30,000-mile intervals.
To improve fuel efficiency, maintain proper tire pressure, follow regular maintenance schedules, drive at steady speeds, and avoid excessive idling. Using cruise control on highways can also help.
Check the tire pressure using a reliable gauge. Inflate the tires to the recommended pressure levels listed on the driver's side door jamb. If the light remains on, it may indicate a puncture or sensor issue. Visit a service center if the problem persists.
To replace a headlight bulb, first turn off the engine and open the hood. Locate the back of the headlight assembly and remove the cover. Disconnect the electrical connector, remove the old bulb, and replace it with a new one. Reattach the connector and cover.
Hyundai recommends using SAE 5W-30 or SAE 5W-20 oil for the Elantra 2021, depending on the engine type. Always refer to the owner's manual for the specific oil type required for your vehicle.
To reset the service reminder light, turn the ignition to the 'ON' position. Use the steering wheel controls to navigate to the 'Service Interval' menu on the dashboard display. Select 'Reset' and confirm the reset when prompted.
A squealing noise during braking often indicates worn brake pads. Inspect the brake pads for wear and replace them if necessary. If the pads are in good condition, the noise could be due to dust or debris. Cleaning the brake components might help.
To enable Lane Keeping Assist, press the 'LKAS' button located on the dashboard or steering wheel. Ensure the system is activated in the vehicle's settings menu. The feature uses cameras to detect lane markings and assist with steering.
If your key fob battery is low, replace it by carefully prying open the fob with a small flat tool. Remove the old battery and insert a new CR2032 battery, ensuring the positive side faces up. Snap the fob back together and test the functionality.
