If towing is necessary, we recommend you have it done by an authorized HYUNDAI dealer or a commercial tow truck service.
If towing service is not available in an emergency, your vehicle may be temporarily towed using a cable or chain secured to the emergency towing hook at the front (or rear) of the vehicle.
