to the black, negative (-) battery/
chassis ground of the assisting
vehicle (3).7. Connect the other end of the sec-
ond jumper cable to the black,
negative (-) chassis ground of
your vehicle (4).
Do not allow the jumper cables to
contact anything except the cor-
rect battery or jumper terminals or
the correct ground. Do not lean
over the battery when making
connections.
8. Start the engine of the assisting
vehicle and let it run at approxi-
mately 2,000 rpm for a few min-
utes. Then start your vehicle.
If your vehicle will not start after a
few attempts, it probably requires
servicing. In this event please seek
qualified assistance. If the cause of
your battery discharging is not
apparent, we recommend that the
vehicle be checked by an authorised
HYUNDAI dealer.Disconnect the jumper cables in the
exact reverse order you connected
them:
1. Disconnect the jumper cable from
the black, negative (-) chassis
ground of your vehicle (4).

If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1. Pull off the road and stop as soon
as it is safe to do so.
2. Place the shift lever in P (Park, for
automatic transmission/dual clutch
transmission vehicle) or neutral (for
manual transmission/dual clutch
transmission vehicle) and set the
parking brake. If the air condition-
ing is ON, turn it OFF.
3. If engine coolant is running out
under the vehicle or steam is com-
ing out from the bonnet, stop the
engine. Do not open the bonnet
until the coolant has stopped run-
ning 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
operating. If the fan is not running,
turn the engine off.4. Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (If the air conditioning had been
in use, it is normal for cold water to
be draining from it when you stop.)
5. If engine coolant is leaking out, stop
the engine immediately and we rec-
ommend that you call an authorised
HYUNDAI dealer for assistance.

Whilst the engine is
running, keep hands,
clothing and tools
away from the mov-
ing parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
WARNING
NEVER remove the
radiator cap or the
drain plug whilst the
engine and radiator
are hot. Hot coolant
and steam may blow out under
pressure, causing serious injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the radiator cap. Wrap a
thick towel around it, and turn it
anticlockwise slowly to the first
stop. Step back whilst the pres-
sure is released from the cool-
ing system. When you are sure
all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning anticlockwise
to remove it.

6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been
lost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
7. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
we recommend that you call an
authorised HYUNDAI dealer for
assistance.

You can check the tyre pressure in
the Assist mode on the cluster.
Refer to the "LCD Display
Modes" in chapter 3.
Tyre pressure is displayed after a
few minutes of driving after initial
engine start up.
If tyre pressure is not displayed when
the vehicle is stopped, "Drive to dis-
play" message will appear. After driv-
ing, check the tyre pressure.
Serious loss of coolant indi-
cates a leak in the cooling
system and we recommend
the system be checked by an
authorised HYUNDAI dealer.
When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.

What to do in an emergency
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is combined with
the low tyre pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the system
may not be able to detect or signal
low tyre pressure as intended.
TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or alter-
nate tyres or wheels on the vehicle
that prevent the TPMS from function-
ing properly. Always check the TPMS
malfunction telltale after replacing
one or more tyres or wheels on your
vehicle to ensure that the replace-
ment or alternate tyres and wheels
allow the TPMS to continue to func-
tion properly.If any of the below happens, we
recommend that the system be
checked by an authorised HYUNDAI
dealer.
1. The low tyre pressure telltale/
TPMS malfunction indicator
does not illuminate for 3 sec-
onds when the ignition switch is
turned to the ON position or the
engine is running.
2. The TPMS malfunction indicator
remains illuminated after blink-
ing for approximately 1 minute.
3. The Low tyre pressure position
telltale remains illuminated.

When the tyre pressure monitoring
system warning indicators are illumi-
nated and a warning message is dis-
played on the cluster LCD display,
one or more of your tyres is signifi-
cantly under-inflated. The low tyre
pressure position telltale will indicate
which tyre is significantly under-
inflated by illuminating the corre-
sponding position light.

The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an authorised
HYUNDAI dealer at the frequencies
indicated to help ensure safe, depend-
able operation of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer
as soon as possible.
These Owner Maintenance vehicle
checks are generally not covered by
warranties and you may be charged
for labour, parts and lubricants used. Performing maintenance work
on a vehicle can be dangerous.
If you lack sufficient knowledge
and experience or the proper
tools and equipment to do the
work, we recommend that the
system be serviced by an autho-
rised HYUNDAI dealer. ALWAYS
follow these precautions for
performing maintenance work:
Park your vehicle on level
ground, move the shift lever
into the P (Park, for automatic
transmission/dual clutch trans-
mission vehicle) position, apply
the parking brake, and place
the ignition switch in the
LOCK/OFF position.
(Continued)
WARNING (Continued)
Block the tyres (front and
back) to prevent the vehicle
from moving.
Remove loose clothing or jew-
ellery that can become entan-
gled in moving parts.
If you must run the engine
during maintenance, do so
out doors or in an area with
plenty of ventilation.
Keep flames, sparks, or smok-
ing materials away from the
battery and fuel-related parts.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windscreen washer fluid
level.
Check for low or under-inflated
tyres.
Whilst operating your vehicle:
Note any changes in the sound of
the exhaust or any smell of exhaust
fumes in the vehicle.
Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead position.
Notice if your vehicle constantly turns
slightly or “pulls” to one side when
travelling on smooth, level road.
When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or
“hard-to-push” brake pedal.
If any slipping or changes in the
operation of your transmissiom
occurs, check the transmissiom fluid
level.
Check the automatic transmission/
dual clutch transmission P (Park)
function.
Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal). Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
WARNING
Diesel Engine
Never manipulate or modify the
injection system whilst running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
high pressure immediately after
stopping the diesel engine.
When the fuel leakage vents out,
it may cause serious body injury.
Any people, who are implanted
with the artificial cardiac pace-
maker, should remain away from
the ECU or the wiring harness by
at least 30 cm, whilst running the
diesel engine. The high currents
of the electronic engine control
system produce a considerable
amount of magnetic fields.
WARNING

7-8
Maintenance
At least monthly:
Check coolant level in the engine
coolant reservoir.
Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
Check the inflation pressures of all
tyres including the spare for tyres
that are worn, show uneven wear,
or are damaged.
Check for loose wheel nuts.
At least twice a year:
(i.e., every Spring and Autumn)
Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windscreen washer spray
and wiper operation. Clean wiper
blades with a clean cloth damp-
ened with washer fluid.
Check headlamp alignment.
Check muffler, exhaust pipes,
shields and clamps.
Check the seat belts for wear and
function.
At least once a year:
Clean body and door drain holes.
Lubricate door hinges and bonnet
hinges.
Lubricate door and bonnet locks
and latches.
Lubricate door rubber weather
strips.
Check the air conditioning system.
Inspect and lubricate automatic
transmission linkage and controls.
Clean the battery and terminals.
Check the brake fluid level.
