Common questions

Is the sound real or generated?
Generated. An electric sound generator produces an artificial engine sound that exits the vehicle alongside the actual diesel exhaust gases.

Can the sound be switched off?
Yes. Double tapping the Auto Start-Stop button switches the generator on or off, and it remembers the setting.

What warranty does it come with?
Hunters Prestige cover their parts with a standard 1-year warranty against manufacturing defects, from the date of purchase.
