Driving your vehicle
Maintenance when trailer towing
Your vehicle will need service more often
when you regularly pull a trailer.
Important items to pay particular atten-
tion to include engine oil, automatic
transmission fluid, axle lubricant and
cooling system fluid. Brake condition is
another important item to frequently
check. Each item is covered in this man-
ual, and the Index will help you find them
quickly. If you’re trailering, it’s a good idea
to review these sections before you start
your trip.
Don’t forget to also maintain your trailer
and towbar. Follow the maintenance
schedule that accompanied your trailer
and check it periodically. Preferably, con-
duct the check at the start of each day’s
driving. Most importantly, all towbar nuts
and bolts should be tight.CAUTION
• Due to higher load during trailer
usage, overheating might occur
in hot days or during uphill driv-
ing. If the coolant gauge indicates
over-heating, switch off the A/C
and stop the vehicle in a safe area
to cool down the engine.
• When towing check transmission
fluid more frequently.
• If your vehicle is not equipped
with the air conditioner, you
should install a condenser fan to
improve engine performance
when towing a trailer.

What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the gear selector lever in P
(automatic transmission) or neutral
(manual transmission) and set the
parking brake. If the air conditioning is
on, turn it off.
3. If engine coolant is running out under
the car or steam is coming out from
the bonnet, stop the engine. Do not
open the bonnet until the coolant has
stopped running or the steaming has
stopped. If there is no visible loss of
engine coolant and no steam, leave
the engine running and check to be
sure the engine cooling fan is operat-
ing. If the fan is not running, turn the
engine off.4. Check to see if the water pump drive
belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check
for coolant leaking from the radiator,
hoses or under the car. (If the air con-
ditioning had been in use, it is normal
for cold water to be draining from it
when you stop).
5. If the water pump drive belt is broken
or engine coolant is leaking out, stop
the engine immediately and we recom-
mend that you call a HYUNDAI autho-
rised repairer.6. If the cause of the overheating cannot
be found, wait until the engine temper-
ature has returned to normal. Then, if
coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
base of the radiator fill opening. Fill the
coolant expansion tank to the halfway
mark. To ensure the correct water to
coolant mix is obtained after top up,
testing by an authorised repairer is
required.
7. Proceed with caution until it is estab-
lished that the engine is operating nor-
mally. If overheating happens again,
we recommend that you call a
HYUNDAI authorised repairer.
CAUTION
• Serious loss of coolant indicates
there is a leak in the cooling sys-
tem and we recommend that the
system be checked by a HYUNDAI
authorised repairer.
• When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.
WARNING
Whilst the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot since steam
and boiling water may be ejected
from the radiator resulting in burns
or scalding.

Maintenance
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
10 7
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.
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.
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.
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.
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
WARNING
Do not disconnect and inspect
spark plugs when the engine is hot.
You may burn yourself.

Maintenance
ENGINE COOLANT
The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and
before travelling to a colder climate.Checking the coolant level
CAUTION
• Do not drive with no engine
coolant. It may cause water pump
failure and engine seizure, etc.
• When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.WARNING
The electric motor (cool-
ing fan) is controlled by
engine coolant tempera-
ture, refrigerant pres-
sure and vehicle speed.
It may sometimes operate even
when the engine is not running.
Use extreme caution when working
near the blades of the cooling fan
so that you are not injured by a
rotating fan blades. As the engine
coolant temperature decreases, the
electric motor will automatically
shut off. This is a normal condition.
WARNING
Removing radiator
cap
• Never attempt to remove the radi-
ator cap whilst the engine is
operating or hot. Doing so might
lead to cooling system and
engine damage and could result
in serious personal injury from
escaping hot coolant or steam.
• Turn the engine off and wait until
it cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back whilst
the pressure is released from the
cooling system.
When you are sure all the pres-
sure has been released, press
down on the cap, using a thick
towel, and continue turning coun-
terclockwise to remove it.
(Continued)
(Continued)
• Even if the engine is not operat-
ing, do not remove the radiator
cap or the drain plug whilst the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.

Maintenance
16 7
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine is
cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, we recommend
that the system be inspected by a
HYUNDAI authorised repairer.
Recommended engine coolant
• When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
• The engine in your vehicle has alu-
minium engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-
ing.
• DO NOT USE alcohol or methanol
coolant or mix them with the specified
coolant.
• Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixture percentage, refer to the fol-
lowing table.
