Engine Coolant Temperature
gauge
This gauge indicates the tempera-
ture of the engine coolant when the
ignition switch or Engine Start/Stop
button is in the ON position.If the gauge pointer moves
beyond the normal range area
toward the "H" 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.
Fuel Gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
NOTICE
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pressure
and could cause severe burns.
Wait until the engine is cool
before adding coolant to the
reservoir.

Low Fuel
• This warning message illuminates
if the fuel tank is nearly empty.
- When the low fuel level warning
light has illuminated.
- When the Trip Computer displays
“--- km” as distance to empty.
Add fuel as soon as possible.
Engine has overheated
• This warning message illuminates
when the engine coolant tempera-
ture is above 120°C (248°F). This
means that the engine is overheat-
ed and may be damaged.
If your vehicle is overheated, refer
to “Overheating” in chapter 6.
Check headlight (if equipped)
This warning message illuminates if
there is a malfunction (burned-out
bulb except LED lamp or circuit mal-
function) with the headlamp. In this
case, have your vehicle inspected by
an authorised HYUNDAI dealer.

Driving your vehicle
When Active ECO 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
transaxle may change.
• The engine noise may get louder.
The above situations are normal
conditions when the Active ECO sys-
tem is activated to improve fuel effi-
ciency.Limitation of Active ECO opera-
tion:
If the following conditions occur
whilst Active ECO 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
transaxle 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 focuses on
dynamic driving by auto-
matically controlling the
steering wheel, engine
and transaxle system.
• When the DRIVE MODE button is
pressed and the SPORT mode is
selected, the SPORT indicator
(yellow) will illuminate.
• When the SPORT mode is activat-
ed, and the engine is turned off
and on it will change to NORMAL
mode. To turn on the SPORT
mode, press the DRIVE MODE
button again.
• If the system is activated:
- After accelerating and releasing
the accelerator pedal, the gear
and engine speed RPM may not
drop as soon as in NORMAL
mode.
- Up-shifting is delayed.
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 haz-
ard warning flasher and place a tri-
angular 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 12 mm
(0.47 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 in section 7. Before winter,
have your coolant tested to ensure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.

Driving your vehicle
Check battery and cables
Winter puts additional burdens on
the battery system.Visually inspect
the battery and cables as
described in chapter 7.We recom-
mend that the level of charge in your
battery be checked by an authorised
HYUNDAI dealer.
Change to "winter weight" oil if
necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
section 8 for recommendations. If
you aren't sure what weight oil you
should use, we recommend that you
consult an authorised HYUNDAI
dealer.Check spark plugs and ignition
system
Inspect your spark plugs as
described in section 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorised HYUNDAI dealer and
most auto parts outlets. Do not use
engine coolant or other types of anti-
freeze as these may damage the
paint finish.

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 transaxle overheating.
If your trailer weighs more than the
maximum trailer weight without trail-
er brakes and you have an automat-
ic transaxle, 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 transaxle.To prevent engine and/or
transaxle 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.
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.
