Maintenance

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS

Engine oil and filter

Fuel filter (For Europe)

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,

more frequent oil and filter changes are

required.

This petrol powered vehicle is equipped

with a lifetime fuel filter that is

integrated with the fuel tank. Regular

maintenance or replacement is not

needed; however, the quality of fuel

used may impact the frequency of

maintenance needed. If there are any

fuel related problems like fuel flow

restriction, surging, loss of power,

hard starting problem etc, fuel filter

inspection or replacement may be

needed. We recommend the fuel filter

be inspected or replaced by a HYUNDAI

authorised repairer.

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

periodically for proper tension and

adjusted as necessary.

Fuel lines, fuel hoses and

connections

CAUTION

When you are inspecting the belt, place

the ignition switch to the lock/off or

ACC position.

Check the fuel lines, fuel hoses and

connections for leakage and damage.

We recommend that the fuel lines, fuel

hoses and connections be replaced by a

HYUNDAI authorised repairer.

Fuel filter (Except Europe)

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.

Vapour hose and fuel filler cap

The vapour hose and fuel filler cap

should be inspected at those intervals

specified in the maintenance schedule.

Make sure that a new vapour hose or

fuel filler cap is correctly replaced.

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 a HYUNDAI authorised

repairer.

Vacuum crankcase ventilation

hoses (if equipped)

Cooling system

Check the cooling system parts, such

as radiator, coolant reservoir, hoses and

connections for leakage and damage.

Replace any damaged parts.

Inspect the surface of hoses for

evidence of heat and/or mechanical

damage. Hard and brittle rubber,

cracking, tears, cuts, abrasions, and

excessive swelling indicate deterioration.

Particular attention should be paid to

examine those hose surfaces nearest to

high heat sources, such as the exhaust

manifold.

Engine coolant

The coolant should be changed at the

intervals specified in the maintenance

schedule.

Inspect the hose routing to assure that

the hoses do not come in contact 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 present.

Hoses should be replaced immediately if

there is any evidence of deterioration or

damage.

Manual transmission fluid/iMT

system actuator fluid

(if equipped)

Inspect the Manual transmission fluid/

iMT system actuator fluid according to

the maintenance schedule.

Automatic transmission fluid

(if equipped)

Automatic transmission fluid should

not be checked under normal usage

conditions.

We recommend that the automatic

transmission fluid is changed by a

HYUNDAI authorised repairer according

to the maintenance schedule.

Air cleaner filter

We recommend that the air cleaner filter

be replaced by a HYUNDAI authorised

repairer.

Spark plugs

(for petrol engine)

Make sure to install new spark plugs of

the correct heat range.

damaged parts immediately.

With the vehicle stopped and engine

off, check for excessive free-play in the

steering wheel.

Check the linkage for bends or damage.

Check the dust boots and ball joints

for deterioration, cracks, or damage.

Replace any damaged parts.

%UDNHꢁFOXWFKꢀIOXLGꢀꢂLIꢀHTXLSSHGꢃ

Check brake/clutch fluid level in the

brake fluid reservoir. The level should

“MAX” (Maximum) marks on the side

of the reservoir. Use only hydraulic

brake/clutch fluid conforming to DOT 4

specification.

Drive shafts and boots
