5Active ECO operationActive ECO helps improve fuel efficiency
by controlling the engine, transaxle and
air conditioner. But fuel-efficiency can be
changed by the driver's driving habits
and road conditions.
 When the Active ECO button is
pressed the ECO indicator (green) will
illuminate to show that the Active ECO
is operating.
 When the Active ECO is activated, it does not turn off even though the
engine is restarted again. To turn off
the system, press the active ECO but-
ton again.
 If Active ECO is turned off, it will return to the ECO mode.
When Active ECO is activated: Vehicle noise may become loud.
 Vehicle speed may drop.
 The air conditioner performance maydecline.
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 normal.
 When driving up a hill: The system will be limited to gain
power when driving uphill because the
engine torque is restricted.
 When using sports mode: The system will be limited according to
the shift location.

5Dual carrigeway/Motorway drivingTyres:Adjust the tyre inflation pressures to
specification. Low tyre inflation pressures
will result in overheating and possible
failure of the tyres.
Avoid using worn or damaged tyres
which may result in reduced traction or
tyre failure.✽ ✽
NOTICENever exceed the maximum tyre infla-
tion pressure shown on the tyres.
Fuel, engine coolant and engine oil:High speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engine
oil.Drive belt:A loose or damaged drive belt may result
in overheating of the engine.

WARNING
 Underinflated or overinflated
tyres can cause poor handling,
loss of vehicle control, and sud-
den tyre failure leading to acci-
dents, injuries, and even death.
Always check the tyres for proper
inflation before driving. For prop-
er tyre pressures, refer to section
8, “Tyres and wheels”.
 Driving on tyres with no or insuf- ficient tread is dangerous. Worn-
out tyres can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tyres
should be replaced as soon as
possible and should never be
used for driving. Always check
the tyre tread before driving your
vehicle. For further information
and tread limits, refer to section
7, “Tyres and wheels”.

5To keep locks from freezingTo 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
heated key with care to avoid injury.Use approved window washer
anti-freeze in systemTo keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the con-
tainer. Window washer anti-freeze is
available from a HYUNDAI authorised
repairer and most auto parts outlets. Do
not use engine coolant or other types of
anti-freeze as these may damage the
paint finish.
Don't let your parking brake
freezeUnder some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when there
is an accumulation of snow or ice around
or near the rear brakes or if the brakes
are wet. If there is a risk the parking
brake may freeze, apply it only temporar-
ily whilst you put the shift lever in P (auto-
matic transaxle) or in first or reverse gear
(manual transaxle) and block the rear
wheels so the vehicle cannot roll. Then
release the parking brake.
Do not park a vehicle on a public road
without the parking brake applied.Don't let ice and snow accumu-
late underneathUnder some conditions, snow and ice
can build up under the fenders and inter-
fere with the steering. When driving in
severe winter conditions where this may
happen, you should periodically check
underneath the vehicle to be sure the
movement of the front wheels and the
steering components is not obstructed.
Carry emergency equipmentDepending on the severity of the weath-
er, you should carry appropriate emer-
gency equipment. Some of the items you
may want to carry include tyre chains,
tow straps or chains, flashlight, emer-
gency flares, sand, a shovel, jumper
cables, a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.Don’t place foreign objects or
materials in the engine compart-
mentPlacement of foreign object or materials
which prevent cooling of the engine, in
the engine compartment, may cause a
failure or combustion. The manufacturer
is not responsible for the damage caused
by such placement.

Driving your vehicle
Driving on grades 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 hot and no longer
operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 45 mph (70
km/h) to reduce the possibility of engine
and transaxle overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transaxle,
you should drive in D (Drive) when tow-
ing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimise heat build up
and extend the life of your transaxle.
CAUTION
 When towing a trailer on steepgrades (in excess of 6%) payclose attention to the engine coolant temperature gauge toensure the engine does not over-heat.
If the needle of the coolant tem-perature gauge moves across thedial towards “H” (HOT), pull over and stop as soon as it is safe todo so, and allow the engine to idle until it cools down. You may pro-ceed once the engine has cooled sufficiently.
 You must decide driving speed depending on trailer weight anduphill grade to reduce the possi-bility of engine and transaxle overheating.
WARNING
Failure to use an approved trailer
wiring harness could result in dam-
age to the vehicle electrical system
and/or personal injury.

Driving your vehicle
When you are ready to leave after park-
ing on a hill
1. With the manual transaxle in Neutralor automatic transaxle in P (Park),
apply your brakes and hold the brake
pedal down whilst you:
 Start your engine;
 Shift into gear; and
 Release the parking brake.
2. Slowly remove your foot from the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance when trailer towing Your vehicle will need service more often
when you regularly pull a trailer.
Important items to pay particular atten-
tion to include engine oil, automatic
transaxle fluid, axle lubricant and cooling
system fluid. Brake condition is another
important item to frequently check. Each
item is covered in this manual, and the
Index will help you find them quickly. If
you’re trailering, it’s a good idea to review
these sections before you start your trip.
Don’t forget to also maintain your trailer
and towbar. Follow the maintenance
schedule that accompanied your trailer
and check it periodically. Preferably, con-
duct the check at the start of each day’s
driving. Most importantly, all towbar nuts
and bolts should be tight.
CAUTION
 Due to higher load during trailer usage, overheating might occurin hot days or during uphill driv-ing. If the coolant gauge indicatesover-heating, switch off the A/C and stop the vehicle in a safe areato cool down the engine.
 When towing check transaxle fluid more frequently.
 If your vehicle is not equipped with the air conditioner, youshould install a condenser fan toimprove engine performance when towing a trailer.

What to do in an emergency
IF THE ENGINE OVERHEATSIf your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as itis safe to do so.
2. Place the shift lever in P (automatic transaxle) or neutral (manual
transaxle) 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 coming out
from the bonnet, stop the engine. Do
not open the bonnet until the coolant
has stopped running 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 operat-
ing. If the fan is not running, turn the
engine off.
4. Check to see if the water pump drive belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check
for coolant leaking from the radiator,
hoses or under the vehicle. (If the air
conditioning had been in use, it is nor-
mal for cold water to be draining from
it when you stop). 5. If the water pump drive belt is broken
or engine coolant is leaking out, stop
the engine immediately and we recom-
mend that you call a HYUNDAI autho-
rised repairer. 6. If the cause of the overheating cannot
be found, wait until the engine temper-
ature has returned to normal. Then, if
coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
base of the radiator fill opening. Fill the
coolant expansion tank to the halfway
mark. To ensure the correct water to
coolant mix is obtained after top up,
testing by a HYUNDAI authorised
repairer is required.
7. Proceed with caution, keeping alert for further signs of overheating. If over-
heating happens again, we recom-
mend that you call a HYUNDAI autho-
rised repairer.
CAUTION
 Serious loss of coolant indicates there is a leak in the cooling sys-tem and we recommend that the system be checked by a HYUNDAIauthorised repairer.
 When the engine overheats from low engine coolant, suddenlyadding engine coolant may causecracks in the engine. To prevent damage, add engine coolantslowly in small quantities.
WARNING
Whilst the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.
