WARNING - Maintenance
work
 Performing maintenance work on a vehicle can be dangerous. You
can be seriously injured whilst
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, we recommend that the
system be serviced by an autho-
rised Kia dealer.
 Working under the bonnet with the engine running is dangerous.
It becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine whilst work-
ing under the bonnet, make cer-
tain that you remove all jewelry
(especially rings, bracelets,
watches, and necklaces) and all
neckties, scarves, and similar
loose clothing before gettingnear the engine or cooling fans.WARNING - Diesel Engine
Never work on injection system with engine running or within 30
seconds after shutting off engine.
High-pressure pump, rail, injectorsand high-pressure pipes are sub-
ject to high pressure even after the
engine stopped. The fuel jet pro-
duced by fuel leaks may cause seri-
ous injury, if it touches the body.
People using pacemakers should
not move than 30cm closer to theECU or wiring harness within the
engine room whilst engine is run-
ning, since the high currents in the
electronic engine control system
produce considerable magneticfields.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the car is being
driven in severe conditions, more fre-quent oil and filter changes are required. Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically forproper tension and adjusted as neces-
sary. Fuel filter (cartridge) A clogged filter can limit the speed at
which the vehicle may be driven, damage
the emission system and cause multiple
issues such as hard starting. If an exces-
sive amount of foreign matter accumu-
lates in the fuel tank, the filter may
require replacement more frequently.
After installing a new filter, run the engine
for several minutes, and check for leaks
at the connections. We recommend that
the fuel filter be replaced by an autho-
rised Kia dealer.
Fuel lines, fuel hoses and con- nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. We
recommend that the fuel lines, fuel hoses
and connections be replaced by an
authorised Kia dealer.
WARNING -
Diesel only
Never work on injection system with engine running or within 30
seconds after shutting off engine.
High pressure pump, rail, injectorsand high pressure pipes are sub-
ject to high pressure even after the
engine stopped. The fuel jet pro-
duced by fuel leaks may cause seri-
ous injury, if it touch the body.
People using pacemakers should
not move than 30cm closer to theECU or wiring harness within the
engine room whilst engine is run-
ning, since the high currents in the
Common Rail system produce con-
siderable magnetic fields.

Maintenance
Timing belt (if equipped)
Inspect all parts related to the timing belt
for damage and deformation. Replace
any damaged parts immediately.
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapour hose or fuelfiller cap is correctly replaced.Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold. Inspect the hose routing to assure that the hoses do not come in contact with
any heat source, sharp edges or movingcomponent which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.Air cleaner filter
We recommend that you use air cleaner
filter for replacement from an authorised
Kia dealer.
Spark plugs (for petrol engine)
Make sure to install new spark plugs of
the correct heat range.
Valve clearance (if equipped)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessary.
We recommend that the system be serv-
iced by an authorised Kia dealer.

Maintenance
WASHER FLUID
Checking the washer fluid level
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available. However, use washer solvent
with antifreeze characteristics in cold cli-
mates to prevent freezing. Checking the parking brake
Check the stroke of the parking brake by
counting the number of “clicks’’ heardwhilst fully applying it from the released
position. Also, the parking brake alone
should securely hold the vehicle on a fair-
ly steep grade. If the stroke is more or
less than specified, we recommend that
the system be serviced by an authorised
Kia dealer.
Stroke :
5~7 “clicks’’ at a force of
20 kg (44 lbs, 196 N).
PARKING BRAKE
WARNING -
Coolant
 Do not use radiator coolant or antifreeze in the washer fluid
reservoir.
 Radiator coolant can severely obscure visibility when sprayed
on the windscreen and may
cause loss of vehicle control or
damage to the paint and bodytrim.
 Windscreen Washer fluid agents contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allowsparks or flame come in contactwith the washer fluid or the wash-
er fluid reservoir. Damage to the
vehicle or occupants could
occur.
 Windscreen washer fluid is poi- sonous to humans and animals.
Do not drink and avoid coming incontact with the windscreen
washer fluid. Serious injury or
death could occur.

Maintenance
For best battery service
 Keep the battery securely mounted.
 Keep the battery top clean and dry.
 Keep the terminals and connectionsclean, tight, and coated with petroleum
jelly or terminal grease.
 Rinse any spilled electrolyte from the battery immediately with a solution of
water and baking soda.
 If the vehicle is not going to be used for an extended time, disconnect the bat-
tery cables.
WARNING - Battery dangers
Always read the following
instructions carefully when
handling a battery.
Keep lighted cigarettes and all other flames or sparks
away from the battery.
Hydrogen, a highly com- bustible gas, is always pres-
ent in battery cells and may
explode if ignited.
Keep batteries out of the reach of children because
batteries contain highly cor-
rosive SULFURIC ACID. Do
not allow battery acid to con-
tact your skin, eyes, clothingor paint finish.
If any electrolyte gets into your eyes, flush your eyes
with clean water for at least
15 minutes and get immedi-ate medical attention.
If electrolyte gets on your
skin, thoroughly wash the
contacted area. If you feel a
pain or a burning sensation,
get medical attention imme-
diately.
(Continued)(Continued)Wear eye protection whencharging or working near a
battery. Always provide
ventilation when working in
an enclosed space.
An inappropriately disposed battery can be harmful to
the environment and humanhealth.
Dispose the battery accord- ing to your local law(s) or
regulation.
The battery contains lead.
Do not dispose of it after
use. We recommend that
you contact an authorised
Kia dealer.
 When lifting a plastic-cased bat- tery, excessive pressure on the
case may cause battery acid to
leak, resulting in personal injury.
Lift with a battery carrier or with
your hands on opposite corners.
 Never attempt to recharge the battery when the battery cables are connected.

If it fits loosely, we recommend that
you consult an authorised Kia dealer.
Main fuse
If the main fuse is blown, it must be
removed as follows:
1. Disconnect the negative battery cable.
2. Remove the nuts shown in the pictureabove.
3. Replace the fuse with a new one of the same rating.
4. Reinstall in the reverse order of removal.
✽✽ NOTICE
If the main fuse is blown, we recom- mend that you consult an authorised
Kia dealer.
CAUTION
After checking the fuse panel in the engine compartment, securely
install the fuse panel cover. If not,electrical failures may occur fromwater leaking in.
