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.
WARNING

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.
NOTICE

OEU054002
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
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
Recommended cold tire infla- tion pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than1.6 km (1 mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure
refer to “Tire and wheels” in section8.
TTIIRR EESS AA NN DD WW HHEEEELLSS

Overinflation or underinfla-
tion can reduce tire life,
adversely affect vehicle han-
dling, and lead to sudden tire
failure. You must always main-tain recommended tire pres-sures.
Warm tires normally exceed recommended cold tire pres-
sures by 28 to 41 kPa (4 to 6
psi). Do not release air fromwarm tires to adjust the pres-sure or the tires will be under-inflated.
Tire underinflation
If the tire pressure drops
repeatedly, the wheel, valve or
tire may be damaged. Underinflation results in reducing fitness of tire and
wheel, excessive wear, poorhandling and reduced fuel
economy. (Continued)
(Continued)
And it can lead to deformation or abnormal wear of wheel,
severe heat build-up, causing
blowouts, tread separationand other tire failures that can
result in the loss of vehicle
control leading to severe
injury or death. This risk is
much higher on hot days and
when driving for long periodsat high speeds.
If the problem is not solved (a
tire frequently needs refilling),we recommend that the sys-
tem be checked by an author-
ized HYUNDAI dealer.
Tire overinflation
Tires with excessively high
pressure can burst because
they are damaged more easily
by road debris, potholes etc.
In addition, they also produce
a harsh ride, excessive wearat the center of the tire tread,and a greater possibility of
damage from road hazards.
