Tachometer
The tachometer indicates the
approximate number of engine revo-
lutions per minute (rpm).Use the tachometer to select the cor-
rect shift points and to prevent lug-
ging and/or over-revving the engine.
Do not operate the engine within
the tachometer's RED ZONE. This
may cause severe engine damage.
Engine coolant temperature
gauge
This gauge indicates the tempera-
ture of the engine coolant when the
ignition switch is in the ON position.
If the gauge pointer moves
beyond the normal range area
toward the “130” position, it indi-
cates overheating that may dam-
age the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to "If the Engine
Overheats" in chapter 6.

The ISG system is to reduce the fuel
consumption by automatically shut-
ting down the engine, when the vehi-
cle is at a standstill (i.e. red stop light,
stop sign, and traffic jam).
The engine is automatically started
upon satisfying the starting condi-
tions.
The ISG system is always active,
when the engine is running.
Information
When the engine is automatically
started by the ISG system, some warn-
ing lights (i.e. ABS, ESC, ESC OFF,
EPS, and parking brake warning
light) may illuminate for a few sec-
onds due to the low battery voltage.
However, it does not indicate a mal-
function with the ISG system.
To activate the ISG system
Prerequisite for activation
The ISG system operates in the fol-
lowing situations.
- The driver's seatbelt is fastened.
- The driver's door and the bonnet
are closed.
- The brake vacuum pressure is
adequate.
- The battery is sufficiently charged.
- The outside temperature is between
-10 °C and 35 °C (14 °F and 95 °F).
- The engine coolant temperature is
not too low.
- The system is not in the diagnostic
mode.
- The steering wheel is not steered
excessively. (for automatic trans-
mission vehicle)
- The vehicle is driven on a steep
incline. (for automatic transmission
vehicle)
Information
• The ISG system is not activated,
when the prerequisites to activate
the ISG system are unsatisfied. In
this case, the ISG OFF button indi-
cator illuminates, and the auto stop
indicator ( ) illuminates in yellow
on the instrument cluster.
• When the above indicator remains
illuminated on the instrument clus-
ter, we recommend that you have
the ISG system checked by a
HYUNDAI authorised repairer.

When ECO mode is activated:
• The acceleration response may be
slightly reduced if 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 ECO mode is acti-
vated to improve fuel efficiency.
Limitation of ECO mode opera-
tion:
If the following conditions occur
whilst 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 to gain
power when driving uphill because
engine torque is restricted.
• When driving the vehicle with the
automatic transmission gear shift
lever in manual mode.
The system will be limited accord-
ing to the shift location.

5-198
Driving your vehicle
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, retight-
en the chains after driving 0.3~0.6
miles (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
(0.59 in) wide to prevent damage
to the chain’s connection.
Winter Precautions
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high
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. 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 affect battery
performance.Inspect the battery
and cables, as specified in the
chapter 7.The battery charging level
can be checked by a HYUNDAI
authorised repairer or in a service
station.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 the chap-
ter 8. When you are not sure about a
type of winter weight oil, consult a
HYUNDAI authorised repairer.
Check spark plugs and ignition
system
Inspect the spark plugs, as speci-
fied in the chapter 7.If necessary,
replace them. Also check all ignition
wirings and components for any
cracks, wear-out, and damage.
To prevent locks from freezing
To prevent the locks from being
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. Carefully
use the heated key to avoid an injury.
NOTICE

5-206
Driving your vehicle
Driving on hills
Reduce speed and shift to a lower
gear before you start down a long or
steep downgrade. If you don't shift
down, you might have to use your
brakes so much that they would get
overheated and may not operate effi-
ciently.
On a long uphill grade, shift down
and reduce your speed to around 70
km/h (45 mph) to reduce the possi-
bility of engine and transmission
overheating.If your trailer weighs more than the
maximum trailer weight without trail-
er brakes and you have automatic
transmission, you should drive in D
(Drive) when towing a trailer.
Operating your vehicle in D (Drive)
when towing a trailer will minimise
heat build-up and extend the life of
your transmission.
To prevent engine and/or trans-
mission overheating:
• When towing a trailer on steep
grades (in excess of 6%) pay
close attention to the engine
coolant temperature gauge to
ensure the engine does not
overheat. If the needle of the
coolant temperature gauge
moves towards "H" (HOT), pull
over and stop as soon as it is
safe to do so, and allow the
engine to idle until it cools
down. You may proceed once the
engine has cooled sufficiently.• If you tow a trailer with the max-
imum gross vehicle weight and
maximum trailer weight, it can
cause the engine or transmis-
sion to overheat. When driving
in such conditions, allow the
engine to idle until it cools
down. You may proceed once the
engine or transmission has
cooled sufficiently.
• When towing a trailer, your vehi-
cle speed may be much slower
than the general flow of traffic,
especially when climbing an
uphill gradient. Use the right
hand lane when towing a trailer
on an uphill gradient. Choose
your vehicle speed according to
the maximum posted speed limit
for vehicles with trailers, the
steepness of the gradient, and
your trailer weight.
• Vehicles equipped with a auto-
matic transmission when towing
a trailer on steep gradients,
need to be aware that the clutch
in the transmission could over-
heat.
NOTICE
Do not connect a trailer lighting
system directly to your vehi-
cle's lighting system. Use an
approved trailer wiring harness.
Failure to do so could result in
damage to the vehicle electrical
system and/or personal injury.
Consult a HYUNDAI authorised
repairer for assistance.

What to do in an emergency
6
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 transmis-
sion/automatic transmission vehi-
cle) 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 a HYUNDAI
authorised repairer for assistance.
‘
IF THE ENGINE OVERHEATS
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
counterclockwise slowly to the
first stop. Step back whilst the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.
WARNING

6-8
What to do in an emergency
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 a
HYUNDAI authorised repairer for
assistance.
•Serious loss of coolant indi-
cates a leak in the cooling
system and we recommend
the system be checked by a
HYUNDAI authorised repairer.
•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

MaintenanceThe electric motor for the cooling fan
is controlled by engine coolant tem-
perature, refrigerant pressure and
vehicle speed. As the engine coolant
temperature decreases, the electric
motor will automatically shut off. This
is a normal condition. If your vehicle
is equipped with GDI, the electric
motor for the cooling fan may begin
to operate at any time and continue
to operate until you disconnect the
negative battery cable.
Recommended engine coolant
• When adding coolant, use only dis-
tilled (deionised) water for your
vehicle and never mix hard water in
the coolant filled at the factory. An
incorrect coolant mixture can result
in serious malfunction or engine
damage.
• The engine in your vehicle has alu-
minium engine parts and must be
protected by an ethylene-glycol
with phosphate based coolant to
prevent corrosion and freezing.
• DO NOT USE alcohol or methanol
coolant or mix them with the spec-
ified coolant.
• Do not use a solution that contains
more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the solu-
tion. The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan blades
of the cooling fan.WARNING
Never remove the
coolant cap/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 removing the
coolant cap/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 pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
