Convenient features
Electric power steering (EPS)
The system assists you with steering
the vehicle. If the engine is off or if
the power steering system becomes
inoperative, the vehicle may still be
steered, but it will require increased
steering effort.
Also, the steering effort becomes
heavier as the vehicle’s speed increases
and becomes lighter as the vehicle’s
speed decreases for better control of the
steering wheel.
Should you notice any change in the
effort required to steer during normal
vehicle operation, we recommend that
the system be checked by an authorized
HYUNDAI dealer.
NOTICE
If the Electric Power Steering System
does not operate normally, the
warning light (
) will illuminate on
the instrument cluster. The steering
wheel may become difficult to control
or operate. Take your vehicle to an
authorized HYUNDAI dealer and
have the system checked as soon as
possible.
i Information
The following symptoms may occur
during normal vehicle operation:
• The steering effort may be high
immediately after placing the ignition
switch in the ON position.
This happens as the system performs
the EPS system diagnostics. When
the diagnostics is completed, the
steering wheel will return to its normal
condition.
• When the battery voltage is low, you
might have to put more steering effort.
However, it is a temporary condition so
that it will return to normal condition
after charging the battery.
• A click noise may be heard from the
EPS relay after the ignition switch
is placed to the ON or LOCK/OFF
position.
• Motor noise may be heard when the
vehicle is at stop or at a low driving
speed.
• When you operate the steering wheel
in low temperature, abnormal noise
may occur. If temperature rises, the
noise will disappear. This is a normal
condition.
WARNING
Never adjust the steering wheel while
driving. You may lose steering control
and cause severe personal injury, death
or accidents.

NOTICE
• To prevent possible damage to the
power window system, do not open
or close two windows or more at the
same time. This will also ensure the
longevity of the fuse.

switch on the driver’s door and the
individual door window switch in
opposite directions at the same time.
If this is done, the window will stop
and cannot be opened or closed.
WARNING
• NEVER leave the keys in your vehicle
with unsupervised children, when the
engine is running.
• NEVER leave any child unattended in
the vehicle. Even very young children
may inadvertently cause the vehicle
to move, entangle themselves in
the windows, or otherwise injure
themselves or others.
• Always double check to make
sure arms, hands, head and other
obstructions are safely out of the way
before closing a window.
• Do not allow children to play with the
power windows. Keep the driver’s
door power window lock switch in
the LOCK position (pressed). Serious

Closing the hood
1. Before closing the hood, check the
following:
• All filler caps in engine compartment
must be correctly installed.
• Gloves, rags or any other
combustible material must
be removed from the engine
compartment.
2. Return the support rod to its clip to
prevent it from rattling.
3. Lower the hood halfway (lifted
approximately 30 cm from the closed
position) and push down to securely
lock in place. Then double check to be
sure the hood is secure.
WARNING
Always double check to be sure that the
hood is firmly latched before driving
away. Check there is no hood open
warning light or message displayed on
the instrument cluster. Driving with the
hood opened may cause a total loss
of visibility, which might result in an
accident.
WARNING
• Before closing the hood, ensure that
all obstructions are removed from
the hood opening. Closing the hood
with an obstruction present in the
hood opening may result in property
damage or severe personal injury.
• Do not leave gloves, rags or any other
combustible material in the engine
compartment. Doing so may cause a
heat-induced fire.
• Do not move the vehicle with
the hood raised. The view will be
blocked and the hood could fall or be
damaged.

• When refueling, always move the
shift lever to the P (Park) position (for
Intelligent Manual Transmission) or
first gear or R (Reverse, for manual
transmission), set the parking brake,
and place the ignition switch to the
LOCK/OFF position. Sparks produced
by electrical components related
to the engine can ignite fuel vapors
causing a fire.
• Do not use matches or a lighter and
do not smoke or leave a lit cigarette
in your vehicle while at a gas station,
especially during refueling.
• Do not over-fill or top-off your
vehicle tank, which can cause petrol
spillage.
• If a fire breaks out during refueling,
leave the vicinity of the vehicle, and
immediately contact the manager
of the gas station and then contact
the local fire department. Follow any
safety instructions they provide.
• If pressurized fuel sprays out, it can
cover your clothes or skin and thus
subject you to the risk of fire and
burns. Always remove the fuel cap
carefully and slowly. If the cap is
venting fuel or if you hear a hissing
sound, wait until the condition stops
before completely removing the cap.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.i Information
• Make sure to refuel your vehicle
according to the “Fuel Requirements”
suggested in the 1 chapter.
• Do not spill fuel on the exterior surfaces
of the vehicle. Any type of fuel spilled
on painted surfaces may damage the
paint.
NOTICE
If the fuel filler cap requires
replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. An incorrect
fuel filler cap can result in a serious
malfunction of the fuel system or
emission control system.

Air conditioning system operation tips
• If the vehicle has been parked in direct
sunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
• After sufficient cooling has been
achieved, switch back from
recirculation mode to fresh mode.
• To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the windows
and sunroof closed.
• During air conditioning system
operation, you may occasionally
notice a slight change in engine speed
as the air conditioning compressor
cycles. This is a normal system
operation characteristic.
• Use the air conditioning system
every month only for a few minutes
to ensure maximum system
performance.
• When using the air conditioning
system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side of
the vehicle. This is a normal system
operation characteristic.
• If you operate the air conditioner
excessively, the difference between
the temperature of the outside air and
that of the windshield could cause the
outer surface of the windshield to fog
up, causing loss of visibility. In this
case, set the mode selection button to
the
position and set the fan speed
control knob to the lowest speed
setting.

Climate control air filter
OIK047401LOIK047401L
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
This filter is installed behind the glove
box. It filters the dust or other pollutants
that enter the vehicle through the
heating and air conditioning system.
We recommend that the climate control
air filter be replaced by an authorized
HYUNDAI dealer according to the
maintenance schedule. If the vehicle is
being driven in severe conditions such
as dusty or rough roads, more frequent
climate control filter inspections and
changes are required.
If the air flow rate suddenly decreases,
we recommend the system be checked
at an authorized HYUNDAI dealer.
i Information
• Replace the filter according to the
Maintenance Schedule.
• If the car is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air filter
inspections and changes are required.
• When the air flow rate suddenly
decreases, we recommend that the
system be checked by an authorized
HYUNDAI dealer.
