When the ECO mode is activated:
•The acceleration response may be
slightly reduced as the accelerator
pedal is depressed moderately.
•The air conditioner performance
may be limited.
•The shift pattern of the automatic
transmission may change.
•The engine noise may get louder.
The above situations are normal
conditions when the ECO mode is
activated, to improve fuel efficiency.
Limitation of the ECO mode oper-
ation:
If the following conditions occur
whilst the ECO mode is operating,
the system operation is limited even
though there is no change in the
ECO indicator.
•When the coolant temperature is
low:
The system will be limited until
engine performance becomes nor-
mal.
•When driving up a hill:
The system will be limited in gain-
ing power when driving uphill
because engine torque is restrict-
ed.
•When driving the vehicle with the
automatic transmission gear shift
lever in manual shift mode:
The system will be limited due to
the shift location.
•When the accelerator pedal is fully
depressed for a few seconds:
The system will be limited, judging
that the driver wants to speed up.
SPORT mode
SPORT mode manages
the driving dynamics by
automatically adjusting the
steering effort, and the
engine and transmission control
logic for enhanced driver perform-
ance.
•When SPORT mode is selected by
pressing the DRIVE MODE button,
the SPORT indicator (orange
colour) will illuminate.
•Whenever the engine is restarted,
the Drive Mode will revert back to
NORMAL mode. If SPORT mode is
desired, re-select SPORT mode
from the DRIVE MODE button.
•When SPORT mode is activated:
- The engine r pm will tend to
remain raised over a certain
length of time even after releas-
ing the accelerator
- Upshifts are delayed when accel-
erating
Information
In SPORT mode, the fuel efficiency
may decrease.

Chain Installation
When installing tyre chains, follow
the manufacturer's instructions and
mount them as tightly as possible.
Drive slowly (less than 30 km/h) with
chains installed. If you hear the
chains contacting the body or chas-
sis, stop and tighten them. If they still
make contact, slow down until the
noise stops. Remove the tyre chains
as soon as you begin driving on
cleared roads.
When mounting snow chains, park
the vehicle on level ground away
from traffic. Turn on the vehicle
Hazard Warning Flasher and place a
triangular emergency warning device
behind the vehicle (if available).
Always place the vehicle in P (Park),
apply the parking brake and turn off
the engine before installing snow
chains.
When using tyre chains:
•Wrong size chains or improperly
installed chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
•Use SAE "S" class or wire
chains.
•If you hear noise caused by
chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
•To prevent body damage,
retighten the chains after driving
0.5~1.0 km.
•Do not use tyre chains on vehi-
cles equipped with aluminium
wheels. If unavoidable, use a
wire type chain.
•Use wire chains less than 15 mm
wide to prevent damage to the
chain's connection.
Winter Precautions
Use high quality ethylene glycol
coolant
Yo u r v e h i c l e i s d e l i v e r e d w i t h h i g h
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in section 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.

Check battery and cables
Winter temperatures increase bat-
tery consumption.Inspect the bat-
tery and cables, as specified in the
chapter 7.The battery charging level
can be checked by an authorised
HYUNDAI dealer or in a service sta-
tion.
Change to "winter weight" oil if
necessary
In some regions during winter, it is
recommended to use the "winter
weight" oil with lower viscosity. For
further information, refer to chapter
8. When you are not sure about a
type of winter weight oil, consult an
authorised HYUNDAI dealer.
Check spark plugs and ignition
system
Inspect the spark plugs, as speci-
fied in chapter 7.If necessary,
replace them. Also check all ignition
wirings and components for any
cracks, wear-out, and damage.
To p r e v e n t l o c k s f r o m f r e e z i n g

frozen, spray approved de-icing fluid
or glycerin into key holes. When a
lock opening is already covered with
ice, spray approved de-icing fluid
over the ice to remove it. When an
internal part of a lock freezes, try to
thaw it with a heated key. Use the
heated key carefully to avoid an
injury.
Use approved window washer
anti-freeze solution in system
To p r e v e n t t h e w i n d o w w a s h e r f r o m
being frozen, add authorised window
washer anti-freeze solution, as spec-
ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from an authorised
HYUNDAI dealer, and most vehicle
accessory outlets. Do not use engine
coolant or other types of anti-freeze
solution, to prevent any damage to
the vehicle paint.

What to do in an emergency
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 vehicle) or
neutral (for manual transmission
vehicle) and set the parking brake.
If the air conditioning 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.
IIFF TTHHEE EENNGGIINNEE OOVVEERRHHEEAATTSS
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.
WA R N I N G
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.
Tu r n t h e e n g i n e o f f a n d w a i t
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.
•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.
CAUTION

Maintenance
Owner maintenance schedule
When you stop for fuel:
•Check the engine oil level.
•Check 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 transmission
occurs, check the transmission fluid
level.
•Check the automatic transmission
P (Park) function.
•Check the parking brake.
•Check for fluid leaks under your vehi-
cle (water dripping from the air con-
ditioning system during or after use
is normal).
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 lug nuts.
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.

Air cleaner filter
We recommend that the air cleaner
filter be replaced by an authorised
HYUNDAI dealer.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check the cooling system parts,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic transmission fluid
Automatic transmission fluid should
not be checked under normal usage
conditions.
We recommend that the automatic
transmission fluid be changed by an
authorised HYUNDAI dealer accord-
ing to the maintenance schedule.
Information
Automatic transmission fluid colour is
basically red. As the vehicle is driven,
the automatic transmission fluid will
begin to look darker.
This is a normal condition. It does not
need to be replaced based on the
colour change.
The use of a non-specified fluid
could result in transmission mal-
function and failure.
Use only specified automatic
transmission fluid. (Refer to

The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant concentration level at least
once a year, at the beginning of the
winter season, and before travelling
to a colder climate.
•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 quanti-
ties.
•Do not drive with no engine
coolant. It may cause water pump
failure and engine seizure, etc.

NOTICE
Removing radiator
cap
•Never attempt to remove the
radiator 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.

Maintenance
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F (MAX) and L (MIN) marks
on the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water. Bring the
level to F (MAX), but do not overfill.
If frequent additions are required, we
recommend that the system be
inspected by an authorised HYUNDAI
dealer.
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times 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 rotating fan blades. As the
engine coolant temperature
decreases, the electric motor
will automatically shut off. This
is a normal condition.
The electric motor (cooling fan)
may operate until you discon-
nect the negative battery cable.

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.
•Even if the engine is not oper-
ating, do not remove the radia-
tor cap or the drain plug whilst
the engine and radiator are
hot. Hot coolant and steam
may still blow out under pres-
sure, causing serious injury.
