Active ECO operation
Active ECO helps improve fuel effi-
ciency by controlling certain engine
and transaxle system operating
parameters. Fuel efficiency depends
on the driver's driving habit and road
condition.
• 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 will remain on until the Active
ECO button is pressed again.
Active ECO does not turn off when
the engine is restarted. To turn off
Active ECO, press the Active ECO
button again.
• If Active ECO is turned off, the sys-
tem will return to normal mode.
When Active ECO is activated :
• The engine noise may get louder.
• The vehicle speed may slightly be
reduced.
• The air conditioner performance
may be affected.
Limitation of Active ECO oper-
ation:
If the following conditions occur while
Active ECO is operating, the system
operation is limited even though
there is no change in the ECO indi-
cator.
• 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
the engine torque is restricted.
• When using 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.

Fuel, engine coolant and engine
oil
High speed travel consumes more
fuel than urban motoring. Do not for-
get 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
tires can cause poor handling,
loss of vehicle control, and
sudden tire failure leading to
accidents, injuries, and even
death. Always check the tires
for proper inflation before
driving. For proper tire pres-
sures, refer to section 8,
“Tires and wheels”.
• Driving on tires with no or
insufficient tread is danger-
ous. Worn-out tires can result
in loss of vehicle control, col-
lisions, injury, and even death.
Worn-out tires should be
replaced as soon as possible
and should never be used for
driving. Always check the tire
tread before driving your vehi-
cle. For further information
and tread limits, refer to sec-
tion 7, “Tires and wheels”.

Chain installation
When installing chains, follow the
manufacturer's instructions and
mount them as tightly as you can.
Drive slowly with chains installed. If
you hear the chains contacting the
body or chassis, stop and tighten
them. If they still make contact, slow
down until it stops. Remove the
chains as soon as you begin driving
on cleared roads.Use high quality ethylene gly-
col 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 assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in section 7. We recommend that the
level of charge in your battery be
checked by an authorized HYUNDAI
dealer.CAUTION
• Chains that are the wrong size
or improperly installed can
damage your vehicle's brake
lines, suspension, body and
wheels.
• Stop driving and retighten the
chains any time you hear them
hitting the vehicle.
WARNING - Tire chains
• The use of chains may
adversely affect vehicle han-
dling.
• Do not exceed 30 km/h (20
mph) or the chain manufactur-
er’s recommended speed
limit, whichever is lower.
• Drive carefully and avoid
bumps, holes, sharp turns,
and other road hazards, which
may cause the vehicle to
bounce.
• Avoid sharp turns or locked-
wheel braking.
WARNING - Mounting
chains
When mounting snow chains,
park the vehicle on level ground
away from traffic. Turn on the
vehicle Hazard Warning flashers
and place a triangular emer-
gency 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.

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 authorized HYUNDAI
dealer.
Check spark plugs and igni-
tion 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
authorized 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.
Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to hap-
pen 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 temporarily
while you put the shift lever in P
(automatic transaxle) and block the
rear wheels so the vehicle cannot
roll. Then release the parking brake.
Don't let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere 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.

Parking on hills
Generally, if you have a trailer
attached to your vehicle, you should
not park your vehicle on a hill. People
can be seriously or fatally injured,
and both your vehicle and the trailer
can be damaged if they unexpected-
ly roll down hill.
However, if you ever have to park
your trailer on a hill, here is how to do
it:
1.Pull the vehicle into the parking
space. Turn the steering wheel in
the direction of the curb (right if
headed down hill, left if headed up
hill).2.If the vehicle has an automatic
transaxle, place the car in P (Park).
3.Set the parking brake and shut off
the vehicle.
4.Place chocks under the trailer
wheels on the down hill side of the
wheels.
5.Start the vehicle, hold the brakes,
shift to neutral, release the parking
brake and slowly release the
brakes until the trailer chocks
absorb the load.
6.Reapply the brakes, reapply the
parking brake and shift the vehicle
to P (Park) for automatic transaxle.
7.Shut off the vehicle and release the
vehicle brakes but leave the park-
ing brake set.CAUTION
• 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
across the dial towards “130/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 driving
speed depending on trailer
weight and uphill grade to
reduce the possibility of
engine and transaxle over-
heating.
WARNING- Parking on a
hill
Parking your vehicle on a hill
with a trailer attached could
cause serious injury or death,
should the trailer break loose or
the brake stops working.

When you are ready to leave after
parking on a hill
1.With automatic transaxle in P
(Park), apply your brakes and hold
the brake pedal down while 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 tow-
ing
Your vehicle will need service more
often when you regularly pull a trail-
er. Important items to pay particular
attention to include engine oil, auto-
matic transaxle fluid, axle lubricant
and cooling system fluid. Brake con-
dition is another important item to
frequently check. Each item is cov-
ered in this manual, and the Index
will help you find them quickly. If
you’re trailering, it is a good idea to
review these sections before you
start your trip.
Do not forget to also maintain your
trailer and hitch. Follow the mainte-
nance schedule that accompanied
your trailer and check it periodically.
Preferably, conduct the check at the
start of each day’s driving. Most
importantly, all hitch nuts and bolts
should be tight.
CAUTION
• Due to higher load during
trailer usage, overheating
might occur in hot days or
during uphill driving. If the
coolant gauge indicates over-
heating, switch off the air con-
ditioner and stop the vehicle
in a safe area to cool down the
engine.
• When towing check transaxle
fluid more frequently.
WARNING- Parking
brake
It can be dangerous to get out
of your vehicle if the parking
brake is not firmly set.
If you have left the engine run-
ning, the vehicle can move sud-
denly. You or others could be
seriously or fatally injured.

What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you will experience a
loss of power, or hear loud pinging or
knocking, the engine is probably too
hot. 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) and
set the parking brake. If the air con-
ditioning is on, turn it off.
3.If engine coolant is running out
under the vehicle or steam is com-
ing out from the hood, stop the
engine. Do not open the hood 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 oper-
ating. 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 leak-
ing from the radiator, hoses or
under the vehicle. (If the air condi-
tioning 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 bro-
ken or engine coolant is leaking
out, stop the engine immediately
and we recommend that you call
an authorized HYUNDAI dealer.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 reser-
voir 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
authorized HYUNDAI dealer.
CAUTION
Serious loss of coolant indi-
cates there is a leak in the cool-
ing system and we recommend
that the system be checked by
an authorized HYUNDAI dealer.
WARNING
While the engine is running,
keep hair, hands and clothing
away from moving parts such
as the fan and drive belts to pre-
vent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to blow out of the
opening and cause serious
burns.
