Maintenance
After checking the fuse box in the
engine compartment, securely
install the fuse box cover. If not,
electrical failures may occur from
water leaking in.
Main fuse
If an electrical system does not oper-
ate with no blown fuse in the engine
room and inner fuse box, the main
fuse inside the battery (+) cap may
be blown.
The main fuse is heavily connected
to many other parts. In this case, we
recommend you to contact a
HYUNDAI authorised repairer.
Multi fuse
If the multi fuse is blown, it must be
removed as follows:
1. Disconnect the negative batterycable.
2. Remove the nuts shown in the pic- ture above.
3. Replace the fuse with a new one of the same rating.
4. Reinstall in the reverse order of removal.
Information
If the multi fuse is blown, we recom-
mend that you consult a HYUNDAI
authorised repairer.

Adding the urea solution
To refill the urea solution fromthe refill hose
1. Press the ignition switch to the
OFF position.
2. Turn the urea solution tank cap in a counterclockwise direction to
open it.
3. Fully insert the refill hose to add the ISO 22241-specified urea
solution over 5 litres or above the
mark on the urea solution tank.
❈ When "Refill Urea tank or vehicle
will not start" message is dis-
played, fill up urea at least 6 litres. ❈
Pay the great caution not to add
the urea solution into the fuel
tank. If not, it surely applies
adverse impact on the vehicle
performance, causing various
malfunctions.
❈ Never use the urea solution mix-
ture with additives or water. It
may allow foreign substances to
enter the urea solution tank. If
so, it surely applies adverse
impact on the vehicle perform-
ance, causing various malfunc-
tions.
❈ Use only the ISO 22241-speci-
fied urea solution. Any unautho-
rised urea solution surely
applies adverse impacts on the
vehicle performance, causing
various malfunctions.
4. Turn the urea solution tank cap in a clockwise direction to securely
close it.
To refill the urea solution fromthe refill bottle
1. Press the ignition switch to the
OFF position
2. Turn the urea solution tank cap in a counterclockwise direction to
open it.
3. Add the ISO 22241-specified urea solution over 5 litres or above the
mark on the urea solution tank.
❈ Pay the great caution not to add
the urea solution into the fuel
tank. If not, it surely applies
adverse impact on the vehicle
performance, causing various
malfunctions.
❈ Pay the great caution not to
over-fill the (completely) fulfilled
urea solution tank by force whilst
refilling the urea solution from
the refill bottle. The over-filled
urea solution tank will be
expanded when it becomes
frozen and this can cause a seri-
ous malfunction of the urea solu-
tion tank or urea solution sys-
tem.
