Convenient features of your vehicle
If you operate 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 knob or button to
the position and fan speed
control to the lower speed.
System Maintenance
Climate control air filter
This filter is installed behind the glove
box. It filters the dust or other pollu-
tants that enter the vehicle through the
heating and air conditioning system.
Have the climate control air filter
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the car is being driven in
severe conditions such as dusty or
rough roads, more frequent air con-
ditioner filter inspections and
changes are required.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.
Checking the amount of air conditioner refrigerant andcompressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
has a negative influence on the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized HYUNDAI dealer.
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage
to the compressor and abnormal
system operation may occur.

FM broadcasts are transmitted at
high frequencies and do not bend to
follow the earth's surface. Because
of this, FM broadcasts generally
begin to fade within short distances
from the station. Also, FM signals are
easily affected by buildings, moun-
tains, and obstructions. This can lead
to undesirable or unpleasant listen-
ing conditions which might lead you
to believe a problem exists with your
radio. The following conditions are
normal and do not indicate radio
trouble: Fading - As your vehicle moves
away from the radio station, the
signal will weaken and sound will
begin to fade. When this occurs,
we suggest that you select another
stronger station.
Flutter/Static - Weak FM signals or large obstructions between the
transmitter and your radio can dis-
turb the signal causing static or
fluttering noises to occur. Reducing
the treble level may lessen this
effect until the disturbance clears. Station Swapping - As an FM sig-
nal weakens, another more power-
ful signal near the same frequency
may begin to play. This is because
your radio is designed to lock onto
the clearest signal. If this occurs,
select another station with a
stronger signal.
Multi-Path Cancellation - Radio signals being received from sever-
al directions can cause distortion
or fluttering. This can be caused by
a direct and reflected signal from
the same station, or by signals
from two stations with close fre-
quencies. If this occurs, select
another station until the condition
has passed.

To prevent damage to the vehicle:
If the engine stalls while you arein motion, do not attempt to
move the shift lever to the P
(Park) position.
If traffic and road conditions
permit, you may put the shift
lever in the N (Neutral) position
while the vehicle is still moving
and press the Engine Start/Stop
button in an attempt to restart
the engine.
Do not push or tow your vehicle to start the engine. To prevent damage to the vehicle:
When the stop lamp fuse is blown,
you can't start the engine normal-
ly. Replace the fuse with a new
one. If you are not able to replace
the fuse, you can start the engine
by pressing and holding the
Engine Start/Stop button for 10 sec-
onds with the Engine Start/Stop
button in the ACC position.
Do not press the Engine Start/Stop
button for more than 10 seconds
except when the stop
lamp fuse is
blown.
For your safety always depress
the brake pedal before starting the
engine.

Driving your vehicle
(Continued)
Under certain conditions suchas repeated launch on steep
grades, the clutch in the trans-
mission could overheat. When
the clutch is overheated, the
safe protection mode engages. If
the safe protection mode
engages, the gear position indi-
cator on the cluster blinks with a
chime sound. At this time, a
warning message will appear on
the LCD display and driving may
not be smooth.
(Continued)(Continued)
If you ignore this warning, the
driving condition may become
worse. To return the normal driv-
ing condition, stop the vehicle
and apply the foot brake for a
few minutes before driving off.
Repetitive kick downs may lead to overheating of the transmis-
sion. This will lead to change in
the vehicle speed shift pattern,
and illuminate some warning
message.
To return the normal driving
condition, refrain from kick
down speed changes. When the
warning message illuminates,
park the vehicle at a safe loca-
tion.
If the ecoshift dual clutch trans- mission starts to become over-
heated, the gear shift character-
istics may change. Gear shifts
may become more abrupt. If
continued operation includes
frequent and continuous
upshifts and downshifts, the
overheat warning message on
the cluster LCD display may illu-
minate.
(Continued)(Continued)
If this occurs, stop the vehicle,
apply the brakes or shift the
vehicle to P (Park), and allow the
transmission to cool with engine
on.
When possible, continue to
drive the vehicle smoothly while
trying to avoid frequent upshift-
ing and downshifting.
Gear shifts may be more notice- able than a conventional auto-
matic transmission. This is a
normal characteristic of this
type of Ecoshift dual clutch
transmission.
During the first 1000 miles, you may feel that the vehicle may not
be smooth when accelerating at
low speed. During this break-in
period, the shift quality and per-
formance of your new vehicle is
continuously optimized.
Always come to a complete stop before shifting into D (Drive) or
R (Reverse).
Do not put the shift lever in N (Neutral) while driving.

Driving your vehicle
D (Drive)
This is the normal driving position.
The transmission will automatically
shift through a seven-gear
sequence, providing the best fuel
economy and power.
For extra power when passing anoth-
er vehicle or driving uphill depress
the accelerator pedal further until
you feel the transmission downshift
to a lower gear.
The DRIVE MODE switch, located
on the shift lever console, allows the
driver to switch from NORMAL mode
to SPORT or ECO mode.
For more information, refer to
"Drive Mode Integrated Control
System" later in this chapter.
Always ensure vehicle is station-
ary, at a complete stop, before
selecting D (Drive).
Manual shift mode
Whether the vehicle is stationary or
in motion, Manual shift mode is
selected by pushing the shift lever
from the D (Drive) position into the
manual gate. To return to D (Drive)
range operation, push the shift lever
back into the main gate.In Manual shift mode, moving the
shift lever backwards and forwards
will allow you to select the desired
range of gears for the current driving
conditions.
+ (Up) : Push the lever forward once
to shift up one gear.
- (Down) : Pull the lever backwards once to shift down one
gear.
Information
• Only the seven forward gears can beselected. To reverse or park the
vehicle, move the shift lever to the R
(Reverse) or P (Park) position as
required.
• Downshifts are made automatically when the vehicle slows down. When
the vehicle stops, 1st gear is auto-
matically selected.
• When the engine rpm approaches the red zone the transmission will
upshift automatically.

ABS is an electronic braking system
that helps prevent a braking skid.
ABS allows the driver to steer and
brake at the same time.
Using ABS
To obtain the maximum benefit from
your ABS in an emergency situation,
do not attempt to modulate your
brake pressure and do not try to
pump your brakes. Depress your
brake pedal as hard as possible.
When you apply your brakes under
conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This is
normal and it means your ABS is
active.
ABS does not reduce the time or dis-
tance it takes to stop the vehicle.
Always maintain a safe distance from
the vehicle in front of you.
ABS will not prevent a skid that
results from sudden changes in
direction, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather con-
ditions.ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing wheel movement can still cause
your vehicle to veer into oncoming
traffic or off the road.
On loose or uneven road surfaces,
operation of the anti-lock brake sys-
tem may result in a longer stopping
distance than for vehicles equipped
with a conventional brake system.
The ABS warning light ( ) will stay
on for several seconds after the igni-
tion switch is in the ON position.
During that time, the ABS will go
through self-diagnosis and the light
will go off if everything is normal. If
the light stays on, you may have a
problem with your ABS. Contact an
authorized HYUNDAI dealer as soon
as possible(Continued)
Drive your vehicle at reduced
speeds during the following
conditions:
Rough, gravel or snow-cov-
ered roads.
On roads where the road sur-
face is pitted or has different
surface height.
Tire chains are installed on
your vehicle.
The safety features of an ABS
or ESC equipped vehicle should
not be tested by high speed
driving or cornering. This could
endanger the safety of yourself
or others.

Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering maneuvers.
ESC checks where you are steering
and where the vehicle is actually
going. ESC applies braking pressure
to any one of the vehicle's brakes
and intervenes in the engine man-
agement system to assist the driver
with keeping the vehicle on the
intended path. It is not a substitute
for safe driving practices. Always
adjust your speed and driving to the
road conditions.
ESC operation
ESC ON condition
When the ignition switch is in the ON
position, the ESC and the ESC OFF
indicator lights illuminate for approxi-
mately three seconds and goes off,
then the ESC is turned on.
When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:
When you apply your brakes under conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This
is normal and it means your ESC is
active.
When the ESC activates, the engine may not respond to the
accelerator as it does under rou-
tine conditions.
Never drive too fast for the road
conditions or too quickly when
cornering. The ESC system will
not prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning
on wet surfaces can result in
severe accidents.

ECO mode
When the Drive Mode isset to ECO mode, the
engine and transmission
control logic are changed
to maximize fuel efficiency.
When the ECO mode is selected by pressing the DRIVE MODE but-
ton, the ECO indicator will illumi-
nate.
If the vehicle is set to ECO mode, when the engine is turned OFF
and restarted the Drive Mode set-
ting will remain in ECO mode.
Information
Fuel efficiency depends on the driver's
driving habit and road condition. When ECO mode 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 ECO mode is acti-
vated to improve fuel efficiency. Limitation of ECO mode opera-
tion:
If the following conditions occur while
ECO mode is operating, the system
operation is limited even though
there is no change in 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 driving the vehicle with the automatic transmission gear shift
lever in manual shift mode:
The system will be limited accord-
ing to the shift location.
When the accelerator pedal is deeply depressed for a few seconds:
The system will be limited, judging
that the driver wants to speed up.
