WARNING- Maintenance
work
• Performing maintenance work on
a vehicle can be dangerous. You
can be seriously injured whilst
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, we recommend that the
system be servied by a HYUNDAI
authorised repairer.
• Working under the bonnet with
the engine running is dangerous.
It becomes even more dangerous
when you wear jewellery or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine whilst work-
ing under the bonnet, make cer-
tain that you remove all jewellery
(especially rings, bracelets,
watches, and necklaces) and all
neckties, scarves, and similar
loose clothing before getting
near the engine or cooling fans.
WARNING- Diesel Engine
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 pro-
duced by fuel leaks may cause seri-
ous injury, if it touches the body.
People using pacemakers should
not move than 30cm closer to the
ECU or wiring harness within the
engine room whilst engine is run-
ning, since the high currents in the
electronic engine control system
produce considerable magnetic
fields.
CAUTION
• Do not put heavy objects or apply
excessive force on top of the
engine cover (if equipped) or fuel
related parts.
• When you inspect the fuel system
(fuel lines and fuel injection
devices), we recommend that you
contact a HYUNDAI authorised
repairer.
• Do not drive long time with the
engine cover (if equipped) removed.
• When checking the engine room,
do not go near fire.
Fuel, washer fluid, etc. are flam-
mable oils that may cause fire.
• Before touching the battery, igni-
tion cables and electrical wiring,
you should disconnect the bat-
tery "-" terminal. You may get an
electric shock from the electric
current.
• When you remove the interior
trim cover with a flat head (-) driv-
er, be careful not to damage the
cover.
• Be careful when you replace and
clean bulbs to avoid burns or
electrical shock.

Maintenance
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
G050100AUN
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 fre-
quent oil and filter changes are required.
G050200BUN
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically for
proper tension and adjusted as neces-
sary.
G050300ATQ-UK
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 exces-
sive amount of foreign matter accumu-
lates 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 a HYUNDAI
authorised repairer.
G050400AEN-UK
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage.
We recommend that the fuel lines, fuel
hoses and connectionsr be replaced by a
HYUNDAI authorised repairer.
WARNING - 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 pro-
duced by fuel leaks may cause seri-
ous 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 whilst engine is run-
ning, since the high currents in the
Common Rail system produce con-
siderable magnetic fields.
CAUTION
In case the fuel filter is clogged due
to not conforming to the mainte-
nance period, the fuel injection
equipment may supply the fuel
insufficiently, which may damage
the fuel injection equipment and
cause the engine to stall at worst
cases.
CAUTION
When you are inspecting the belt,
place the ignition switch in the
LOCK/OFF or ACC position.

G050600AUN-UK
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.
G050700AUN
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. 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 contact with
any heat source, sharp edges or moving
component which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, 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.
G050800AEN
Air cleaner filter
We recommend that the air cleaner filter
be replaced by a HYUNDAI authorised
repairer.
G050900BUN-UK

Make sure to install new spark plugs of
the correct heat range.
G051000AEN-UK
Valve clearance (if equipped)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessary.
We recommend that the system be serv-
iced by a HYUNDAI authorised repairer.
G051100AUN
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
G051200AUN
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
G051300AUN
Manual transmission fluid
(if equipped)
Inspect the manual transmission fluid
according to the maintenance schedule.
G051400ATQ-UK
Automatic transmission fluid
(if equipped)
The fluid level should be in the "HOT"
range of the dipstick, after the engine
and transmission are at normal operating
temperature. Check the automatic trans-
mission fluid level with the engine run-
ning and the transmission in neutral, with
the parking brake properly applied.
✽NOTICE
If your vehicle is not equipped with the
automatic transmission level gauge, we
recommend that the automatic trans-
mission fluid inspected by a HYUNDAI

WASHER FLUID
G120100AUN-UK
Checking the washer fluid level
The reservoir is translucent so that you
can check the level with a quick visual
inspection.
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available.However, use washer solvent with
antifreeze characteristics in cold climates
to prevent freezing.
G140100AFD-UK
Checking the parking brake
Check the stroke of the parking brake by
counting the number of “clicks’’ heard
whilst fully applying it from the released
position. Also, the parking brake alone
should securely hold the vehicle on a fair-
ly steep grade. If the stroke is more or
less than specified, we recommend that
the system be serviced by a HYUNDAI
authorised repairer.
Stroke : 7 “clicks’’ at a force of
44 lbs (20 kg, 196 N).
WARNING - Coolant
• Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
• Radiator coolant can severely
obscure visibility when sprayed
on the windscreen and may
cause loss of vehicle control or
damage to paint and body trim.
• Windscreen washer fluid agents
contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allow
sparks or flame to contact the
washer fluid or the washer fluid
reservoir. Damage to the vehicle
or occupants could occur.
• Windscreen washer fluid is poi-
sonous to humans and animals.
