When recharging the battery,
observe the following precautions:
The battery must be removed from
the vehicle and placed in an area
with good ventilation.
Do not allow cigarettes, sparks, or flame near the battery.
Watch the battery during charging, and stop or reduce the charging
rate if the battery cells begin
gassing (boiling) violently or if the
temperature of the electrolyte of
any cell exceeds 120°F (49°C).
Wear eye protection when check- ing the battery during charging.
Disconnect the battery charger in the following order.
1. Turn off the battery charger main switch.
2. Unhook the negative clamp from the negative battery terminal.
3. Unhook the positive clamp from the positive battery terminal. Before performing maintenance or
recharging the battery, turn off all
accessories and stop the engine.
The negative battery cable must be removed first and installed last
when the battery is disconnected.Reset items
Items should be reset after the bat-
tery has been discharged or the bat-
tery has been disconnected.

FUSES
❈ Left side : Normal , Right side : Blown
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will melt.
If the electrical system does not
work, first check the driver’s side
fuse panel.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized Kia
dealer.
Three kinds of fuses are used: blade
type for lower amperage rating, car-tridge type, and multi fuse for higheramperage ratings.
WARNING- Fuse replace-
ment
Never replace a fuse with any- thing but another fuse of the
same rating.
A higher capacity fuse could cause damage and possibly a
fire.
Never install a wire or alu- minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
a possible fire.
Do not arbitrarily modify or add-on electric wiring to the
vehicle.
CAUTION
Do not use a screwdriver or anyother metal object to removefuses because it may cause ashort circuit and damage thesystem.

Maintenance
3. Pull the suspected fuse straightout. Use the removal tool provided
on the engine compartment fuse
panel cover.
4. Check the removed fuse; replace it if it is blown.
Spare fuses are provided in theengine compartment fuse panel.
5. 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.
If you do not have a spare, use a fuse of the same rating from a circuityou may not need for operating thevehicle, such as the power outletfuse.
If the head lamp, turn signal lamp,
stop signal lamp, fog lamp, DRL, tail
lamp, HMSL do not work and the
fuses are OK, check the fuse panel
in the engine compartment. If a fuse
is blown, it must be replaced.
✽ ✽ NOTICE
If the headlamp, fog lamp, turn sig-
nal lamp, or tail lamp malfunction
even without any problem to the
lamps, have the vehicle checked by
an authorized Kia dealer for assis-
tance.
Fuse switch
Always set the fuse switch to the ON
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.

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. 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 - Fuse Panel
Covers
The contact points of theswitches may wear out withexcessive use. Please refrainfrom excessive use of theswitches (except for long-termparking for over 1 month).
CAUTION
Always securely install the fusepanel cover in the engine com-partment to protect againstelectrical failure which mayoccur from water contact.Listen for the audible clickingsound to ensure fuse panelcover is securely fastened.

Multi fuse
✽ ✽NOTICE
Do not disassemble nor assemble the
multi fuse when it is secured with
nuts and bolts. Incorrect or partial
assembly torque may cause a fire.
Have the vehicle checked by an
authorized Kia dealer.
Main fuse
✽ ✽NOTICE
Do not disassemble nor assemble the
multi fuse when it is secured with
nuts and bolts. Incorrect or partial
assembly torque may cause a fire.
Have the vehicle checked by an
authorized Kia dealer.
✽ ✽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 securelyclosed, moisture may enter thesystem and damage the electri-cal components.

Maintenance
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid valve.
Purge Control Solenoid Valve(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.
3. Exhaust emission control system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate gov-
ernmental safety and emissions reg-
ulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
If you use unauthorized electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
Engine exhaust gas precautions
(carbon monoxide)
Carbon monoxide can be present with other exhaust fumes.
Therefore, if you smell exhaust
fumes of any kind inside your vehi-
cle, have it inspected and repaired
immediately. If you ever suspect
exhaust fumes are coming into
your vehicle, drive it only with all
the windows fully open. Have your
vehicle checked and repaired
immediately.
WARNING - Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.
