position before using the vehicle.
If you move the switch to the OFF
position, some items such as audio
and digital clock must be reset and
transmitter (or smart key) may not
work properly. When the switch is
Off, the caution indicator will be dis-
played on the instrument cluster.
Always place the fuse switch in the
ON position while driving the vehicle.
If the switch is located in the “OFF”
position, a caution indicator will be
displayed in the cluster.
Engine compartment fuse
replacement
1. Turn the ignition switch and all
other switches off.
2. Remove the fuse panel cover by
pressing the tab and pulling the
cover up. When the blade type
fuse is disconnected, remove it by
using the clip designed for chang-
ing fuses located in the engine
compartment fuse box. Upon
removal, securely insert reserve
fuse of the same rating.3. Check the removed fuse; replace it
if it is blown. To remove or insert
the fuse, use the fuse puller in the
engine compartment fuse panel.
4. Push in a new fuse of the same
rating, and make sure it fits tightly
in the clips. If it fits loosely, consult
an authorized Kia dealer.
CAUTION
After checking the fuse panel in
the engine compartment,
securely install the fuse panel
cover through the audible click-
ing sound.
If not, electrical failures may
occur from water contact.

Maintenance
✽ ✽
NOTICE
The electronic system may not func-
tion correctly even when the engine
compartment and internal fuse
box’s individual fuses are not dis-
connected. In such case the cause of
the problem may be disconnection
of the main fuse (BFT type), which is
located inside the positive battery
terminal (+) cap.
Since the main fuse is designed more
intricately than other parts, have the
vehicle checked by an authorized
Kia dealer.CAUTION
Visually inspect the battery cap
to ensure it is securely closed.
If the battery cap is not securely
closed, moisture may enter the
system and damage the electri-
cal components.
