ECO mode (Active ECO)
Active ECO helps improve
fuel efficiency by control-
ling certain engine and
transmission system
operating parameters.
Fuel efficiency depends on the dri-
ver's driving habit and road condi-
tion.
When the DRIVE MODE switch is
pressed and the ECO mode is
selected, the ECO indicator
(green) will illuminate to show that
the Active ECO is operating.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
transmission 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 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
engine torque is restricted.
When using the automatic trans-
mission Sports mode:
The system will be limited accord-
ing to the shift location.

✽ ✽
NOTICE
• Install AutoSock®(fabric snow
chain or equivalent product) on
the rear tires for 2WD vehicles or
on all four tires for AWD vehicles.
It should be noted that installing
AutoSock
®(fabric snow chain) on
the tires will provide a greater
driving force, but will not prevent
side skids.
• Do not install studded tires with-
out first checking local, state and
municipal regulations for possible
restrictions against their use.
Chain Installation
When installing AutoSock®(fabric
snow chain or equivalent product),
follow the manufacturer's instructions
and mount them as tightly possible.
Drive slowly (less than 20 mph (30
km/h)) 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 the noise stops. Remove the
AutoSock
®(fabric snow chain or
equivalent product) as soon as you
begin driving on cleared roads.When mounting AutoSock
®(fabric
snow chain or equivalent product),
park the vehicle on level ground
away from traffic.
Turn on the vehicle Hazard Warning
Flasher 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 tire
chains.AutoSock®is a Registered trade-
mark of AutoSock.
Winter precaution
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 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. The level of charge in your
battery can be checked by an author-
ized retailer of Genesis Branded
products or a service station. When using AutoSock
®(fabric
snow chain):
Wrong size chains or improp-
erly installed chains can dam-
age your vehicle's brake lines,
suspension, body and wheels.
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 driv-
ing 0.3~0.6 miles (0.5~1.0 km).

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)
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 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
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
call the nearest authorized retailer
of Genesis Branded products for
assistance.

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,
call an authorized retailer of
Genesis Branded products for
assistance.
Serious loss of coolant indi-
cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized retailer of Genesis Branded
products.
CAUTION
NEVER remove the
radiator cap, drain
plug and heater hose
connector cap while
the engine and radia-
tor are hot. Hot coolant and
steam may blow out under pres-
sure, 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 while 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

Maintenance
The 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.Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between the F and the L marks on
the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring
the level to the F mark, but do not
overfill. If frequent additions are
required, we recommend that you
see an authorized retailer of Genesis
Branded products for a cooling sys-
tem inspection.
Recommended engine coolant
When adding coolant, use only
deionized water, distilled water or
soft water for your vehicle and
never mix hard water in the coolant
filled at the factory.
An improper coolant mixture can
result in severe malfunction or
engine damage.
The engine in your vehicle has alu-
minum engine parts and must be
protected by an ethylene-glycol-
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
solution. 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

Maintenance
For mixing percentage, refer to the
following table:
✽ ✽
NOTICE
If in doubt about the mix ratio, a
50% water and 50% antifreeze mix
is the easiest to mix together as it
will be the same quantity of each. It
is suitable to use for most tempera-
ture ranges of -31°F and higher.
Changing engine coolant
Have coolant changed by an author-
ized retailer of Genesis Branded
products according to the
Maintenance Schedule at the begin-
ning of this chapter.

Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
Engine coolant can severely
obscure visibility when
sprayed on the windshield
and may cause loss of vehicle
control resulting in an acci-
dent.
Engine coolant may also
cause damage to paint and
body trim.
WARNING
To prevent damage to engine
parts, put a thick towel around
the radiator cap before refilling
the coolant to prevent the
coolant from overflowing into
engine parts, such as the gener-
ator.
