Hyundai recommends following a maintenance schedule that includes regular oil changes every 7,500 miles, tire rotations every 7,500 miles, and air filter replacements every 30,000 miles. For hybrid components, it's crucial to have them inspected during each service visit.
To reset the TPMS, ensure that all tires are inflated to the recommended pressure. Then, drive the car at a speed above 20 mph for at least 10 minutes. The system should automatically reset. If the issue persists, consult a Hyundai dealer.
The Hyundai Sonata Hybrid 2021 is designed to operate efficiently on regular unleaded gasoline with an octane rating of 87 or higher. Using higher octane fuel is not necessary and offers no benefit.
To improve fuel efficiency, maintain proper tire pressure, adhere to recommended maintenance schedules, drive at moderate speeds, and use the Eco mode whenever possible. Avoid excessive idling and aggressive acceleration.
If the hybrid system warning light illuminates, safely pull over, turn off the vehicle, and restart it. If the light persists, it's important to have the vehicle inspected by a Hyundai dealer as soon as possible to diagnose potential issues.
To change the cabin air filter, open the glove compartment and remove the damper. Press the sides of the glove box inward to release it. The cabin air filter is located behind a cover; remove the old filter and replace it with a new one. Reassemble in reverse order.
Yes, it is normal. The Hyundai Sonata Hybrid 2021 features an auto start-stop system that turns off the engine at stops to conserve fuel and reduce emissions. The engine will automatically restart when you release the brake pedal.
To connect your smartphone, enable Bluetooth on your device. In the vehicle, press the 'Setup' button, select 'Bluetooth', then 'Add New'. Choose your vehicle on your phone's Bluetooth menu, confirm the passkey match, and complete the pairing process.
If the vehicle does not start, check the 12-volt battery and connections. Ensure the vehicle is in 'Park' and the brake pedal is fully depressed. If the problem persists, contact roadside assistance or a Hyundai dealer for further assistance.
The regenerative braking system is automatically engaged when you apply the brakes. It converts kinetic energy into electrical energy to recharge the hybrid battery. For optimal use, anticipate stops to allow the system to maximize energy recovery.
