Driving your vehicle
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 or dual clutch trans-
mission 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 to gain
power when driving uphill because
engine torque is restricted.
When using the automatic trans-
mission or dual clutch transmission
Sports mode:
The system will be limited accord-
ing to the shift location.
When the accelerator pedal is
deeply depressed for a few sec-
onds: 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 wheel, engine
and transmission system.
When the SPORT mode is select-
ed by pressing the DRIVE MODE
button, the SPORT indicator (yel-
low colour) will illuminate.
Restarting the engine in SPORT
mode resets the DRIVE mode to
COMFORT mode. Thus, when
necessary, reselect the SPORT
mode.
When the SPORT mode is activat-
ed:
- The RPM (revolutions per min-
utes) level is maintained over a
certain length of time, even after
releasing the accelerator.
- Up-shifting timing is delayed,
whilst accelerating.
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 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
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 in chapter 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
The winter temperature increases
the battery consumption.Inspect
the battery and cables, as speci-
fied in chapter 7.The battery charg-
ing level can be checked by an
authorised HYUNDAI dealer 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 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 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.Use approved window washer
anti-freeze solution in system
To prevent the window washer from
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 so are the
most vehicle accessory outlets. Do
not use engine coolant or other types
of anti-freeze solution to prevent any
damage to the vehicle paint.

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 to reduce the possibility of
engine and transmission overheat-
ing.
If your trailer weighs more than the
maximum trailer weight without trail-
er brakes and you have an automat-
ic transmission/dual clutch transmis-
sion, 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.
You must decide your vehicle
speed according to the trailer
weight and uphill grade.
Vehicles equipped with a dual
clutch transmission when tow-
ing a trailer on steep grades, the
clutch in the transmission could
overheat.
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 an authorised
HYUNDAI dealer for assistance.

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/dual
clutch 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.
