Driving your vehicle
• The dual clutch transmission can
be thought of as an automatically
shifting manual transmission. It
gives the driving feel of a manual
transmission, yet provides the
ease of a fully automatic transmis-
sion.
• When D (Drive) is selected, the
transmission will automatically shift
through the gears similar to a con-
ventional automatic transmission.
Unlike a traditional automatic
transmission, the gear shifting can
sometimes be felt and heard as the
actuators engage the clutches and
the gears are selected.
• The dual clutch transmission incor-
porates a dry-type dual clutch
mechanism, which allows for better
acceleration performance and
increased fuel efficiency while driv-
ing. But it differs from a conven-
tional automatic transmission
because it does not incorporate a
torque converter. Instead, the tran-
sition from one gear to the next is
managed by clutch slip, especially
at lower speeds.As a result, shifts are sometimes
more noticeable, and a light vibra-
tion can be felt as the transmission
shaft speed is matched with the
engine shaft speed. This is a nor-
mal condition of the dual clutch
transmission.
• The dry-type clutch transfers
torque more directly and provides
a direct-drive feeling which may
feel different from a conventional
automatic transmission. This may
be more noticeable when launch-
ing the vehicle from a stop or when
traveling at low, stop-and-go vehi-
cle speeds.
• When rapidly accelerating from a
lower vehicle speed, the engine
rpm may increase dramatically as
a result of clutch slip as the dual
clutch transmission selects the cor-
rect gear. This is a normal condi-
tion.
• When accelerating from a stop on
an incline, press the accelerator
smoothly and gradually to avoid
any shudder feeling or jerkiness.• When traveling at a lower vehicle
speed, if you release the accelera-
tor pedal quickly, you may feel
engine braking before the trans-
mission changes gears. This
engine braking feeling is similar to
operating a manual transmission at
low speed.
• When driving downhill, you may
wish to move the gear shift lever to
Manual Shift mode and downshift
to a lower gear in order to control
your speed without using the brake
pedal excessively.
• When you turn the engine on and
off, you may hear clicking sounds
as the system goes through a self-
test. This is a normal sound for the
dual clutch transmission.
• During the first 1,500 km (1000
miles), you may feel that the vehi-
cle may not be smooth when accel-
erating at low speed. During this
break-in period, the shift quality
and performance of your new vehi-
cle is continuously optimized.

Indicator lights
When the ignition switch is pressed
to the ON position, the ESC indicator
light illuminates, then goes off if the
ESC system is operating normally.
The ESC indicator light blinks when-
ever the ESC is operating.
If the ESC indicator light stays on,
your vehicle may have a malfunction
with the ESC system. When this
warning light illuminates we recom-
mend that the vehicle be checked by
an authorized HYUNDAI dealer as
soon as possible.
The ESC OFF indicator light comes
on when the ESC is turned off with
the button.Driving with wheels and tires with
different sizes may cause the ESC
system to malfunction. Before
replacing tires, make sure all four
tires and wheels are the same
size. Never drive the vehicle with
different sized wheels and tires
installed.
ESC OFF usage
When Driving
The ESC OFF mode should only be
used briefly to help free the vehicle if
stuck in snow or mud, by temporarily
stopping operation of the ESC, to
maintain wheel torque.
To turn ESC off while driving, press
the ESC OFF button while driving on
a flat road surface.
NOTICE
■ESC indicator light (blinks)
■ ESC OFF indicator light (comes on)When the ESC is blinking, this
indicates the ESC is active:
Drive slowly and NEVER attempt
to accelerate. NEVER turn the
ESC off while the ESC indicator
light is blinking or you may lose
control of the vehicle resulting in
an accident.
WARNING

Driving your vehicle
The Lane Keeping Assist System
helps detect lane markers on the
road with a camera at the front wind-
shield, and assists the driver's steer-
ing to help keep the vehicle between
lanes.
When the system detects the vehicle
straying from its lane, it alerts the
driver with a visual and audible warn-
ing, while applying a slight counter-
steering torque, trying to prevent the
vehicle from moving out of its lane.
LANE KEEPING ASSIST SYSTEM (LKAS) (IF EQUIPPED)
OAE056048
The Lane Keeping Assist
System is not a substitute for
safe driving practices, but a
convenience function only. It is
the responsibility of the driver
to always be aware of the sur-
rounding and steer the vehicle.
WARNING
Take the following precautions
when using the Lane Keeping
Assist System (LKAS):
•Do not steer the steering
wheel suddenly when the
steering wheel is being assist-
ed by the system.
•LKAS helps to prevent the
driver from moving out of the
lane unintentionally by assist-
ing the driver's steering.
However, the driver should
not solely rely on the system
but always pay attention on
the steering wheel to stay in
the lane.
(Continued)
WARNING
(Continued)
•The operation of the LKAS
can be cancelled or not work
properly according to road
condition and surroundings.
Always be cautious when
driving.
•Do not disassemble the LKAS
camera temporarily to tint the
window or attach any types of
coatings and accessories. If
you disassemble the camera
and assemble it again, we rec-
ommend that you take your
vehicle to an authorized
HYUNDAI dealer and have the
system checked for calibra-
tion.
•When you replace the wind-
shield glass, LKAS camera or
related parts of the steering
wheel, we recommend that
you take your vehicle to an
authorized HYUNDAI dealer
and have the system checked
for calibration.

8. Insert the jack handle into the jack
and turn it clockwise, raising the
vehicle until the tire clears the
ground. Make sure the vehicle is
stable on the jack.9. Loosen the lug nuts with the wheel
lug nut wrench and remove them
with your fingers. Remove the
wheel from the studs and lay it flat
on the ground out of the way.
Remove any dirt or debris from
the studs, mounting surfaces, and
wheel.
10. Install the spare tire onto the
studs of the hub.
11. Tighten the lug nuts with your fin-
gers onto the studs with the
smaller end of the lug nuts clos-
est to the wheel.
12. Lower the vehicle to the ground
by turning the jack handle coun-
terclockwise.13. Use the wheel lug nut wrench to
tighten the lug nuts in the order
shown. Double-check each lug
nut until they are tight. After
changing tires, we recommend
that an authorized HYUNDAI
dealer tighten the lug nuts to their
proper torque as soon as possi-
ble.The wheel lug nut should
be tightened to 11~13 kgf.m
(79~94 lbf.ft).

When driving with the compact spare
tire mounted to your vehicle:
• Check the tire pressure after
installing the compact spare tire.
The compact spare tire should be
inflated to 420 kPa (60 psi).
• Do not take this vehicle through an
automatic car wash while the com-
pact spare tire is installed.
• Do not use the compact spare tire
on any other vehicle because this
tire has been designed especially
for your vehicle.
• The compact spare tire's tread life
is shorter than a regular tire.
Inspect your compact spare tire
regularly and replace worn com-
pact spare tires with the same size
and design, mounted on the same
wheel.
• Do not use more than one compact
spare tire at a time.
• Do not tow a trailer while the com-
pact spare tire is installed.When the original tire and wheel
are repaired and reinstalled on the
vehicle, the lug nut torque must be
set correctly. The correct lug nut
tightening torque is 11~13 kgf.m
(79~94 lbf.ft).NOTICE
To prevent damaging the com-
pact spare tire and your vehicle:
•Drive slowly enough for the
road conditions to avoid all
hazards, such as a potholes
or debris.
•Avoid driving over obstacles.
The compact spare tire diame-
ter is smaller than the diame-
ter of a conventional tire and
reduces the ground clearance
approximately 25 mm (1 inch).
•Do not use tire chains on the
compact spare tire. Because
of the smaller size, a tire chain
will not fit properly.
•Do not use the compact spare
tire on any other wheels, nor
should standard tires, snow
tires, wheel covers or trim
rings be used with the com-
pact spare wheel.

Maintenance
Tire rotation
To equalize tread wear, HYUNDAI
recommends that the tires be rotated
every 12,000 km (7,500 miles) or
sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of the tire.
Replace the tire if you find any of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check
lug nut tightness (proper torque is
11~13 kgf·m [79~94 lbf·ft]).
Disc brake pads should be inspected
for wear whenever tires are rotated.
Information
The outside and inside of the unsym-
metrical tire is distinguishable. When
installing an unsymmetrical tire, be
sure to install the side marked "out-
side" face the outside. If the side
marked "inside" is installed on the
outside, it will have a negative effect
on vehicle performance.

• It is permissible to add 20 kPa (3 psi) to the standard tire pressure specification if colder temperatures are
expected soon. Tires typically lose 7 kPa (1 psi) for every 7°C (12°F) temperature drop. If extreme temperature
variations are expected, recheck your tire pressure as necessary to keep them properly inflated.
• An air pressure generally decreases, as you drive up to a high-altitude area above sea level. Thus, if you plan
to drive a high-altitude area, check the tire pressures in advance. If necessary, inflate them to a proper level
(Air inflation per altitude: +10 kPa/1 km (+2.4 psi/1 mile).
