This Owner’s Manual for the 2021 Elantra (CN7) is your essential guide to fully understanding every feature, function, and specification of your vehicle. Inside, you will find detailed descriptions of exterior and interior design, dashboard and instrument-panel layouts, seating and safety features (seat belts, airbags, child restraint systems), and all comfort and convenience functions — from door locks, windows, mirrors, lighting, climate control, to infotainment and storage.
Moreover, the manual covers important operational instructions for driving — from starting the engine and transmission use to braking, steering, and wheel / tire maintenance — as well as guidance for emergency situations (flat tire, battery issues, towing, breakdowns) and scheduled maintenance (fluids, filters, bulbs, tires, etc.). It ensures that both drivers and owners can safely, efficiently, and confidently use their Elantra day-to-day, while preserving long-term reliability and safety.
