Maintenance
Main fuse
If the main fuse is blown, it must be
removed as follows:
1. Turn off the engine.
2. Disconnect the negative batterycable.
3. Remove the nuts shown in the pic- ture above.
4. Replace the fuse with a new one of the same rating.
5. Reverse these steps to reinstall the main fuse.
✽ ✽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.
✽ ✽NOTICE- Random wiring pro-
hibited when retrofitting equip-
ment
Use of random wiring in the vehicle
might cause danger due to failure
and damage of the vehicle’s per-
formance.
Using random wires especially when
retrofitting AVN or theft alarm sys-
tem, remote engine control, car
phone or radio, might damage the
vehicle or cause fire.
✽ ✽ NOTICE- Remodeling
Prohibited
Do not rewire your vehicle in any
way as doing so may affect the per-
formance of several safety features
in your vehicle. Rewiring your vehi-
cle may also void your warranty and
cause you to be responsible for any
subsequent vehicle damage which
may result.CAUTION
Visually inspect the battery capto ensure it is securely closed.If the battery cap is not securelyclosed, moisture may enter thesystem and damage the electri-cal components.

LIGHT BULBS
Bulb replacement precaution
Please keep extra bulbs on hand
with appropriate wattage ratings in
case of emergencies.
Refer to “Bulb Wattage” in chapter 9.
When changing lamps, first turn off
the engine at a safe place, firmly
apply the parking brake and detach
the battery’s negative (-) terminal.
Use only bulbs of the specified
wattage.✽ ✽ NOTICE
• If the light bulb or lamp connector
is removed while the lamp is still
on, the fuse box's electronic sys-
tem may log it as a malfunction.
Therefore, a lamp malfunction
incident may be recorded as a
Diagnostic Trouble Code (DTC) in
the fuse box.
• It is normal for an operating lamp to flicker momentarily. This is due
to a stabilization function of the
vehicle’s electronic control device.
If the lamp lights up normally
after momentarily blinking, then
it is functioning as normal.
However, if the lamp continues to
flicker several times or turns off
completely, there may be an error
in the vehicle’s electronic control
device. Please have the vehicle
checked by an authorized Kia
dealer immediately.
WARNING- Working on
the lights
Prior to working on the lights,
firmly apply the parking brake,
ensure that the engine
start/stop button is in OFF posi-
tion and turn off the lights to
avoid sudden movement of the
vehicle that may cause burning
your fingers or receiving an
electric shock.
CAUTION -Light replace-
ment
Be sure to replace the burned- out bulb with one of the samewattage rating. Otherwise, itmay cause damage to the fuseor electric wiring system.
CAUTION -Headlamp
Lens
To prevent damage, do notclean the headlamp lens withchemical solvents or strongdetergents.

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.
