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 whilst
driving. But it differs from a con-
ventional 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
travelling 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 travelling 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 optimised.

Indicator lights
When the ignition switch is set 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 authorised HYUNDAI dealer as
soon as possible.
The ESC OFF indicator light comes
on when ESC is turned off.Driving with wheels and tyres with
different sizes may cause the ESC
system to malfunction. Before
replacing tyres, make sure all four
tyres and wheels are the same
size. Never drive the vehicle with
different sized wheels and tyres
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 ESC, to main-
tain wheel torque.
To turn ESC off whilst driving, press
the ESC OFF button whilst driving on
a flat road surface.
NOTICE
■ESC indicator light (blinks)
■ ESC OFF indicator light (comes on)When ESC is blinking, this indi-
cates the ESC is active:
Drive slowly and NEVER attempt
to accelerate. NEVER turn the
ESC off whilst the ESC indicator
light is blinking or you may lose
control of the vehicle resulting in
an accident.

Driving your vehicle
The Lane Keeping Assist (LKA) sys-
tem helps detect lane markers on the
road with a camera at the front wind-
screen, and assists the driver's
steering 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, whilst applying a slight counter-
steering torque, trying to help pre-
vent the vehicle from moving out of
its lane.

The Lane Keeping Assist (LKA)
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-
roundings and steer the vehicle.
WARNING
Take the following precautions
when using the Lane Keeping
Assist (LKA) system:
Do not turn the steering wheel
suddenly when the steering
wheel is being assisted by the
system.
LKA system helps to prevent
the driver from moving out of
the lane unintentionally by
assisting 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.
WARNING
(Continued)
(Continued)
The operation of the LKA sys-
tem can be cancelled or not
work properly according to
road condition and surround-
ings. Always be cautious
when driving.
Do not disassemble the LKA
system camera temporarily to
tint the window or attach any
types of coatings and acces-
sories. If you disassemble the
camera and assemble it again,
we recommend that you take
your vehicle to an authorised
HYUNDAI dealer and have the
system checked for calibra-
tion.
When you replace the wind-
screen glass, LKA system
camera or related parts of the
steering wheel, we recom-
mend that you take your vehi-
cle to an authorised HYUNDAI
dealer and have the system

8. Insert the jack handle into the jack
and turn it clockwise, raising the
vehicle until the tyre clears the
ground. Make sure the vehicle is
stable on the jack.9. Loosen the lug nuts with the wheel
brace 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 tyre 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 anti-
clockwise.13. Use the wheel brace to tighten
the lug nuts in the order shown.
Double-check each lug nut until
they are tight. After changing
tyres, we recommend that an
authorised HYUNDAI dealer
tighten the lug nuts to their prop-
er torque as soon as possible.
The wheel lug nut should be
tightened to 11~13 kgf.m
(79~94 lbf.ft).

When driving with the compact spare
tyre mounted to your vehicle:
Check the tyre pressure after
installing the compact spare tyre.
The compact spare tyre should be
inflated to 420 kPa (60 psi).
Do not take this vehicle through an
automatic car wash whilst the com-
pact spare tyre is installed.
Do not use the compact spare tyre
on any other vehicle because this
tyre has been designed especially
for your vehicle.
The compact spare tyre's tread life
is shorter than a regular tyre.
Inspect your compact spare tyre
regularly and replace worn com-
pact spare tyres with the same size
and design, mounted on the same
wheel.
Do not use more than one compact
spare tyre at a time.
Do not tow a trailer whilst the com-
pact spare tyre is installed.When the original tyre 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 tyre and your vehi-
cle:
Drive slowly enough for the
road conditions to avoid all
hazards, such as a potholes
or debris.
Avoid driving over obstacles.
The compact spare tyre diam-
eter is smaller than the diame-
ter of a conventional tyre and
reduces the ground clearance
approximately 25 mm (1 inch).
Do not use tyre chains on the
compact spare tyre. Because
of the smaller size, a tyre
chain will not fit properly.
Do not use the compact spare
tyre on any other wheels, nor
should standard tyres, snow
tyres, wheel covers or trim
rings be used with the com-
pact spare wheel.

ed or damaged parts immediately.
Brake fluid
Check the brake fluid level in the
brake fluid reservoir. The level should
be between the MIN and the MAX
marks on the side of the reservoir.
Use only hydraulic brake fluid con-
forming to DOT 3 or DOT 4 specifi-
cation.
Parking brake
Inspect the parking brake system
including the parking brake pedal
and cables.
Brake discs, pads, calipers
and rotors
Check the pads, the disc, and the
rotor for any excessive wear-out.
Inspect calipers for any fluid leakage.

Maintenance
Tyre rotation
To equalize tread wear, HYUNDAI
recommends that the tyres be rotat-
ed every 12,000 km (7,500 miles) or
sooner if irregular wear develops.
During rotation, check the tyres for
correct balance.
When rotating tyres, check for
uneven wear and damage. Abnormal
wear is usually caused by incorrect
tyre pressure, improper wheel align-
ment, out-of-balance wheels, severe
braking or severe cornering. Look for
bumps or bulges in the tread or side
of the tyre. Replace the tyre if you
find any of these conditions. Replace
the tyre if fabric or cord is visible.
After rotation, be sure to bring the
front and rear tyre pressures to spec-
ification 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 tyres are rotated.
Information
The outside and inside of the unsym-
metrical tyre is distinguishable. When
installing an unsymmetrical tyre, 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.

■ With a full-size spare tyre (if equipped)
■Without a spare tyre
Do not use the compact spare
tyre for tyre rotation.
Do not mix bias ply and radial
ply tyres under any circum-
stances. This may cause
unusual handling characteris-
tics that may cause loss of
vehicle control resulting in an
accident.

It is permissible to add 20 kPa (3 psi) to the standard tyre pressure specification if colder temperatures are
expected soon. Tyres typically lose 7 kPa (1 psi) for every 7°C (12°F) temperature drop. If extreme temperature
variations are expected, recheck your tyre 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 tyre pressures in advance. If necessary, inflate them to a proper level
(Air inflation per altitude: +10 kPa/1 km (+2.4 psi/1 mile).
