1: Inspect and if necessary correct or replace. Inspect drive belt tensioner, idler and alternator pulley and if necessary correct or
replace.
*
2: Check the engine oil level and leak every 500 km (350 miles) or before starting a long trip.

4: This maintenance schedule depends on fuel quality. It is applicable only when using a qualified fuel < "EN590 or equivalent">.If the diesel fuel specification doesn't meet the EN590, it must be replaced more frequently. If there are some important safety
matters like fuel flow restriction, surging, loss of power, hard starting problem etc, replace the fuel filter immediately regardless
of maintenance schedule and we recommend that you consult an authorized HYUNDAI dealer for details.

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 frequent oil and filter changes
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 connections be
replaced by an authorized HYUNDAI
dealer.
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.
When you are inspecting the
belt, place the ignition switch to
the LOCK/OFF or ACC position.

Maintenance
PARKING BRAKE
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 : 5~6 “clicks’’ at a force of
20 kg (44 lbs, 196 N).
Draining water from fuel filter
The fuel filter in the diesel engine
operates the critical function of sepa-
rating water from the fuels and accu-
mulating the water in its bottom.
When enough water is accumulated
inside the fuel filter, the warning light
illuminates with the ignition switch in
the ON position.
In this case, we recommend you to
have the system checked by an
authorized HYUNDAI dealer.
When the accumulated water is
not drained at a proper timing,
water may permeate in the fuel fil-
ter, damaging the major vehicle
components, such as the fuel sys-
tem.
Information
When replacing the fuel filter car-
tridge, we recommend that you use
parts for replacement from an author-
ized HYUNDAI dealer.

EMISSION CONTROL SYSTEM
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 system
In order to assure the proper function
of the emission control systems, it is
recommended that you have your
car inspected and maintained by an
authorized HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.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. For the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
•To prevent the vehicle from
misfiring during dynamome-
ter testing, turn the Electronic
Stability Control (ESC) sys-
tem off by pressing the ESC
switch.
•After dynamometer testing is
completed, turn the ESC sys-
tem back on by pressing the
ESC switch again.
CAUTION

7-114
Maintenance
Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void
your warranties.
Diesel particulate filter (DPF)
(if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot in the
exhaust gas.
The DPF system automatically burns
(or oxidizes) the accumulated soot in
accordance with the driving situa-
tions, unlike a disposable air filter.
In other words, the accumulated soot
is automatically purged out by the
engine control system and by the high
exhaust-gas temperature at normal/
high driving speeds.
However, when the vehicle is continu-
ally driven at repeated short distance
or driven at low speed for a long time,
the accumulated soot may not be
automatically removed because of low
exhaust gas temperature. In this case,
the accumulated soot is out of the
detection range, the soot oxidization
process does not occur, and the
Malfunction Indicator Lamp ( )
Illuminates.
•Use only UNLEADED FUEL
for gasoline engine.
•Do not operate the vehicle
when there are signs of
engine malfunction, such as
misfire or a noticeable loss of
performance.
•Do not misuse or abuse the
engine. Examples of misuse
are coasting with the engine
off and descending steep
grades in gear with the engine
off.
(Continued)
(Continued)
•Do not operate the engine at
high idle speed for extended
periods (5 minutes or more).
•Do not modify or tamper with
any part of the engine or
emission control system. All
inspections and adjustments
must be made by an author-
ized HYUNDAI dealer.
•Avoid driving with a very low
fuel level. If you run out of
gasoline, it could cause the
engine to misfire and result in
excessive loading of the cat-
alytic converter.
