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 con-
ditions, more frequent oil and filterchanges are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
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 excessive amount of
foreign matter accumulates 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 authorized HYUNDAI
dealer.
Fuel lines, fuel hoses and con- nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connection be
replaced by an authorized HYUNDAI
dealer.
When you are inspecting the
belt, place the ignition switch in
the LOCK/OFF or ACC position.
CAUTION
In case the fuel filter is clogged
due to not conforming to the
maintenance period, the fuel
injection equipment may supply
the fuel insufficiently, which
may damage the fuel injectionequipment and cause the
engine to stall at worst cases.
CAUTION
Diesel only
Never work on injection system with engine running or within 30seconds after shutting off
engine. High pressure pump,
rail, injectors and high pressurepipes are subject to high pres-
sure even after the engine
stopped. The fuel jet produced
by fuel leaks may cause serious
injury, if it touch the body.
People using pacemakers
should not move than 30cm
closer to the ECU or wiring har-
ness within the engine room
while engine is running, sincethe high currents in the
Common Rail system produce
considerable magnetic fields.

Maintenance
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapor hose or fuel filler cap is cor-rectly replaced.
Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evi- dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. 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 con-
tact with any heat source, sharp
edges or moving component whichmight cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
We recommend that the air cleaner
filter be replaced by an authorized
HYUNDAI dealer.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.

Maintenance
Checking the parking brake
Check the stroke of the parking
brake by counting the number of
“clicks’’ heard while fully applying it
from the released position. Also, the
parking brake alone should securely
hold the vehicle on a fairly steep
grade. If the stroke is more or less
than specified, we recommend that
the system be serviced by an author-
ized HYUNDAI dealer.
Stroke : 7 “clicks’’ at a force of
20 kg (44 lbs, 196 N).
Draining water from fuel filter
The fuel filter for diesel engine plays
an important role of separating water
from fuel and accumulating the waterin its bottom.
If water accumulates inthe fuel filter, the warninglight comes on when the
ignition switch is in the ONposition.
If this warning light turned
on, we recommend that
the system be serviced by
an authorized HYUNDAI
dealer.
Fuel filter cartridge replace- ment
When replacing the fuel filter car-
tridge, we recommend that you
use parts for replacement from an
authorized HYUNDAI dealer.

If the water accumulated in the
fuel filter is not drained at prop-
er times, damages to the major
parts such as the fuel system
can be caused by water perme-
ation in the fuel filter.

Maintenance
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport in your vehicle.
Your vehicle is equipped with an emission control system to meet all
emission regulations. There are three emission control
systems which are as follows.
(1) Crankcase emission control sys-tem
(2) Evaporative emission control sys- tem
(3) Exhaust emission control systemIn order to assure the proper function
of the emission control systems, it is
recommended that you have your
vehicle inspected and maintained by
an authorized HYUNDAI dealer orother repair shops that use qualifiedtechnicians in accordance with the
maintenance schedule in this manu-al.1. Crankcase emission control system
The positive crankcase ventilation
system is employed to prevent air
pollution caused by blow-by gases
being emitted from the crankcase.This system supplies fresh filtered air
to the crankcase through the air
intake hose. Inside the crankcase,
the fresh air mixes with blow-by
gases, which then pass through the
PCV valve into the induction system.
2. Evaporative emission con-trol System
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.
Canister
Fuel vapors generated inside the fueltank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surgetank 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.

Maintenance
Diesel Particulate Filter (if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot emitted
from the vehicle.
Unlike a disposable air filter, the DPF
system automatically burns (oxi-
dizes) and removes the accumulated
soot according to the driving condi-
tion. In other words, the active burn-
ing by engine control system and
high exhaust gas temperature
caused by normal/high driving condi-
tion burns and removes the accumu-lated soot.
However, if the vehicle continues to
be driven in short distance repeated-
ly or at low speed for a long time, the
accumulated soot may not be auto-
matically removed because of low
exhaust gas temperature. In this par-
ticular case, if the amount of soot is
out of detection limit, the DPF warn-
ing indicator ( ) will illuminate. In order to start the DPF regenera-
tion and to stop the DPF warning
lamp illuminating, drive the vehicle in
a safety driving circumstance with
more than 60km/h (37 mph) vehiclespeed or with more than secondgear engaged and 1500 ~ 2000
engine rpm for a certain time (for
about 25 minutes).
If the DPF warning indicator( )
continues to blink or "check emissionsystem" message comes on in the
cluster in spite of the above proce-
dure, we recommend that the system
be checked by an authorized
HYUNDAI dealer.
If you continue to drive with the indi-
cator light blinking for a long time, theDPF system can be damaged and
fuel consumption can be worsen.Diesel Fuel (if equipped with DPF) It is recommended to use the regulated automotive diesel
fuel for diesel vehicle equippedwith the DPF system.
If you use diesel fuel including high sulfur (more than 50 ppm
sulfur) and unspecified addi-
tives, it can cause the DPF sys-
tem to be damaged and whitesmoke can be emitted.
