Introduction
Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components ofthe fuel system.
Gasolines for cleaner air
To help contribute to cleaner air, KIA rec-
ommends that you use gasolines treated
with detergent additives, which help pre-
vent deposit formation in the engine.
These gasolines will help the engine run
cleaner and enhance performance of theEmission Control System.
Operation in foreign countries
If you are going to drive your vehicle in
another country, be sure to:
Observe all regulations regarding reg-istration and insurance.
Determine that acceptable fuel is avail- able. Diesel engine
Diesel fuel
Diesel engine must be operated only on
commercially available diesel fuel that
complies with EN 590 or comparable
standard. (EN stands for "European
Norm"). Do not use marine diesel fuel,
heating oils, or non-approved fuel addi-
tives, as this will increase wear andcause damage to the engine and fuel
system. The use of non-approved fuels
and / or fuel additives will result in a limi-
tation of your warranty rights.
Diesel fuel of above cetane 52 is used in
your vehicle. If two types of diesel fuel
are available, use summer or winter fuel
properly according to the following tem-
perature conditions.
Above -5°C (23°F) ... Summer type diesel
fuel.
Winter type diesel fuel.
Watch the fuel level in the tank very care-
fully : If the engine stops through fuel fail-
ure, the circuits must be completely
purged to restart.
CAUTION
Do not let any gasoline or water enter the tank. This would make it
necessary to drain it out and to bleed the lines to avoid jammingthe injection pump and damagingthe engine.
In winter, in order to cut down incidents due to freezing, paraffinoil may be added to the fuel if the temperature drops below -10°C
(14°F). Never use more than 20% paraffin oil.
CAUTION - Diesel Fuel
It is recommended to use the regu-
lated automotive diesel fuel for
diesel vehicle equipped with theDPF system.
If you use diesel fuel including highsulfur (more than 50 ppm sulfur) and unspecified additives, it can
cause the DPF system to be dam-aged and white smoke can be emit- ted.

Maintenance
Engine compartment precautions (Diesel engine)
The piezo injector operates at highvoltage (maximum 200v). Therefore,
the following accidents may occur.
- Direct contact with the injector or
injector wiring may cause electric
shock or damage your muscle or
nerve system.
- The electromagnetic wave from the operating injector may cause the arti-
ficial heart pacemaker to malfunction.
Follow the safety tips provided below, when you are checking the engine
room while the engine is running.
- Do not touch the injector, injector
wirings, and the engine computer
while the engine is running.
- Do not remove the injector connector while the engine is running.
- People using pacemakers must not go near the engine while the engine
is starting or running.
WARNING - Maintenance
work
Performing maintenance work on a vehicle can be dangerous. You
can be seriously injured while
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorized KIA dealer.
Working under the hood 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 while work-
ing under the hood, make certain
that you remove all jewelry (espe-
cially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose cloth-
ing before getting near theengine or cooling fans.WARNING - Diesel Engine
Never work on the injection system with the engine running or within30 seconds after shutting off the
engine. High-pressure pump, rail,
injectors and high-pressure pipes
are subject to high pressure even
after the engine stopped. The fuel
jet produced by fuel leaks may
cause serious injury, if it touches
the body. People using pacemakers
should not move more than 30cm
closer to the ECU or wiring harness
within the engine room while the
engine is running, since the high
currents in the electronic engine
control system produce consider-
able magnetic fields.

problem etc, replace the fuel filter immediately regardless of maintenance schedule and consult an authorized KIA dealer for
details.

Maintenance
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 vehicle is
being driven in severe conditions, morefrequent oil and filter changes arerequired. 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. Fuel filters should be
installed by an authorized KIA dealer.
Fuel lines, fuel hoses and con- nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have
an authorized KIA dealer replace any
damaged or leaking parts immediately.
WARNING -
Diesel only
Never work on the injection system with the engine running or within30 seconds after shutting off the
engine. High pressure pump, rail,
injectors and high pressure pipes
are subject to high pressure even
after the engine stops. The fuel jet
produced by fuel leaks may cause
serious injury, if it touches the
body. People using pacemakers
should not more move than 30 cm
closer to the ECU or wiring harness
within the engine room while the
engine is running, since the highcurrents in the Common Rail sys-
tem produce considerable magnet-ic fields.
