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.

Drive belts

WARNING

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.

Diesel only

Never work on injection system

with engine running or within 30

seconds after shutting off engine.

High pressure pump, rail, injectors

and high pressure pipes are sub-

ject to high pressure 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 harness within the

engine room while engine is run-

ning, since the high currents in the

Common Rail system produce

considerable magnetic fields.

NOTICE

When you are inspecting the belt,

place the ignition switch in the

LOCK/OFF or ACC position.

Vapor hose and fuel filler cap

Vacuum crankcase ventilation

hoses (if equipped)

Air cleaner filter

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.

We recommend that the air cleaner

filter be replaced by an authorized

HYUNDAI dealer.

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.

Spark plugs

Make sure to install new spark plugs

of the correct heat range.

WARNING

Inspect the hose routing to assure

that the hoses do not come in con-

tact with any heat source, sharp

edges or moving component which

might 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.

Do not disconnect and inspect

spark plugs when the engine is

hot. You may burn yourself.

Cooling system

Continuously Variable Transaxle

fluid (if equipped)

NOTICE

Check cooling system components,

such as radiator, coolant reservoir,

hoses and connections for leakage

and damage. Replace any damaged

parts.

The use of non-specified fluid (even

marked as compatible with genuine)

could result in shift quality deteriora-

tion and vibrations, eventually, the

transaxle failure.

Use only specified Continuously

Variable Transaxle fluid. (Refer to

"Recommended lubricants and

capacities" in chapter 8.)

Continuously Variable Transaxle fluid

should not be checked under normal

usage conditions.

But, the Continuously Variable

Transaxle fluid should be changed

under severe usage conditions. We

recommend that the Continuously

Variable Transaxle fluid changed by

an authorized HYUNDAI dealer

according to the maintenance sched-

ule. (Refer to “Maintenance Under

Severe Usage Conditions” in this

chapter. )

Coolant

The coolant should be changed at

the intervals specified in the mainte-

nance schedule.

Brake hoses and lines

Manual transaxle fluid

(if equipped)

Inspect the manual transaxle fluid

according to the maintenance sched-

ule.

Visually check for proper installation,

chafing, cracks, deterioration and

any leakage. Replace any deteriorat-

ed or damaged parts immediately.

i

Information

Continuously Variable Transaxle fluid

color is basically light amber.

Brake fluid

As the vehicle is driven, the

Continuously Variable Transaxle fluid

will begin to look darker.

Check brake fluid level in the brake

fluid reservoir. The level should be

between "MIN" (Minimum) and

"MAX" (Maximum) marks on the side

of the reservoir. Use only hydraulic

brake fluid conforming to DOT 3 or

DOT 4 specification.

It is normal condition and you should

not judge the need to replace the fluid

based upon the changed color.

damage. Replace any damaged

parts and, if necessary, repack the

grease.

Brake discs, pads, calipers and

rotors

Check the pads for excessive wear,

discs for run out and wear, and

calipers for fluid leakage.

Air conditioning refrigerant

(if equipped)

Check the air conditioning lines and

connections for leakage and dam-

age.

Suspension mounting bolts

Check the suspension connections

for looseness or damage. Retighten

to the specified torque.

Steering gear box, linkage &

boots/lower arm ball joint

With the vehicle stopped and engine

off, check for excessive free-play in

the steering wheel.

Check the linkage for bends or dam-

age. Check the dust boots and ball

joints for deterioration, cracks, or

damage. Replace any damaged

parts.
