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.
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 inthe engine compartment,securely install the fuse panelcover through the audible click-ing sound.
If not, electrical failures mayoccur from water contact.

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.

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 light,
firmly apply the parking brake,
ensure that the ignition switch
is turned to the LOCK position
and turn off the lights to avoid
sudden movement of the vehi-
cle and 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.

Specifications & Consumer information

Recommended SAE viscosity
number
Always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or draining
any lubricant. This is especially impor-
tant in dusty or sandy areas and when
the vehicle is used on unpaved roads.
Cleaning the plug and dipstick areas
will prevent dirt and grit from entering
the engine and other mechanisms
that could be damaged. Engine oil vis-
cosity (thickness) has an effect on fuel
economy and cold weather operating
(engine start and engine oil flowabili-
ty). Lower viscosity engine oils can
provide better fuel economy and cold
weather performance; however, high-
er viscosity engine oils are required
for satisfactory lubrication in hot
weather. Using oils of any viscosity
other than those recommended could
result in engine damage. When
choosing an oil, consider the range of
temperature your vehicle will be oper-
ated in before the next oil change.
Proceed to select the recommended
oil viscosity from the chart.

is not available in your country, select the proper engine oil using
the engine oil viscosity chart.

2: For better fuel economy, it is recommended to use the engine oil of a viscosity grade SAE 5W-20 (API SM / ILSAC GF-4 / ACEA A5).
However, if the engine oil is not available in your country, select the
proper engine oil using the engine oil viscosity chart.
