*6: The fuel filter is considered to be maintenance free but periodic inspection is recommended for this maintenance schedule
depending on fuel quality. If there are some important matters like fuel flow restriction, surging, loss of power, or hard starting
problems etc, we recommend replacing the fuel filter immediately regardless of maintenance schedule and consulting with an
authorised HYUNDAI dealer for details.

the factory. An improper coolant mixture can result in serious malfunction or engine damage. For your convenience, it can bere-
placed prior to it's interval when you do maintenance of other items.
