But it differs from a conventional
automatic transmission because it
does not incorporate a torque con-
verter. Instead, the transition 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 vehicle 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 1000 miles (1,500
km), you may feel that the vehicle
may not be smooth when acceler-
ating at low speed. During this
break-in period, the shift quality
and performance of your new vehi-
cle is continuously optimized.To reduce the risk of serious
injury or death:
ALWAYS check the surround-
ing areas near your vehicle for
people, especially children,
before shifting a vehicle into
D (Drive) or R (Reverse).
Before leaving the driver's
seat, always make sure the
shift lever is in the P (Park)
position, then set the parking
brake, and place the Engine
Start/Stop button in the OFF
position. Unexpected and
sudden vehicle movement
can occur if these precautions
are not followed.
Do not use aggressive engine
braking (shifting from a high-
er gear to a lower gear) on
slippery roads. This could
cause the tires to slip and may
result in an accident.

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 while driving, press
the ESC OFF button while driving on
a flat road surface.To prevent damage to the trans-
mission:
Do not allow wheel(s) of one
axle to spin excessively while
the ESC, ABS, and parking brake
warning lights are displayed.
The repairs would not be cov-
ered by the vehicle warranty.
Reduce engine power and do
not spin the wheel(s) excessive-
ly while these lights are dis-
played.
When operating the vehicle on a
dynamometer, make sure the
ESC is turned off (ESC OFF light
illuminated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
Vehicle Stability Management
(VSM)
The Vehicle Stability Management
(VSM) is a function of the Electronic
Stability Control (ESC) system. It
helps the vehicle stay stable when
accelerating or braking suddenly on
wet, slippery and rough roads where
traction over the four tires can sud-
denly become uneven.
i
NOTICE
Take the following precautions
when using the Vehicle Stability
Management (VSM):
ALWAYS check the speed and
the distance to the vehicle
ahead. The VSM is not a sub-
stitute for safe driving prac-
tices.
Never drive too fast for the
road conditions. The VSM sys-
tem will not prevent acci-
dents. Excessive speed in bad
weather, slippery and uneven
roads can result in severe
accidents.

Lane Keeping Assist system helps
detect lane markers on the road with
a front view camera at the front
windshield, 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, while applying a slight counter-
steering torque, trying to help pre-
vent the vehicle from moving out of
its lane.

Lane Keeping Assist system is
not a substitute for safe driving
practices, but a convenience
function only. It is the responsi-
bility of the driver to always be
aware of the surroundings and
steer the vehicle.
WARNING
Take the following precautions
when using Lane Keeping
Assist 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.
The operation of LKA system
can be cancelled or not work
properly according to road
condition and surroundings.
Always be cautious when
driving.

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, have an author-
ized HYUNDAI dealer tighten the
lug nuts to their proper torque as
soon as possible.The wheel lug
nut should be tightened to
79~94 lbf·ft (11~13 kgf·m).If you have a tire gauge, check the
tire pressure (see "Tires and
Wheels" in chapter 8 for tire pressure
instructions.). If the pressure is lower
or higher than recommended, drive
slowly to the nearest service station
and adjust it to the recommended
pressure. Always reinstall the valve
cap after checking or adjusting tire
pressure. If the cap is not replaced,
air may leak from the tire. If you lose
a valve cap, buy another and install it
as soon as possible. After changing
tires, secure the flat tire and return
the jack and tools to their proper stor-
age locations.

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 1 inch (25 mm).
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.

should be inspected according to the
intervals specified in the mainte-
nance schedule.
Engine Clutch Actuator Fluid
The engine clutch actuator fluid level
should be inspected or replaced to
the intervals specified in the mainte-
nance schedule.
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake Fluid
Check the brake fluid level in the
brake the fluid reservoir. The level
should be between the MIN and the
MAX marks on the side of the reser-
voir. Use only hydraulic brake fluid
conforming to DOT 4 specification.
Parking Brake
Inspect the parking brake system
including the parking brake pedal
and cables.
Brake Discs, Pads, Calipers
and Rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
Exhaust Pipe and Muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the engine
and listen carefully for any exhaust
gas leakage. Tighten connections or
replace parts as necessary.
Suspension Mounting Bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.

Maintenance
Tire Rotation
To equalize tread wear, HYUNDAI
recommends that the tires be rotated
every 7,500 miles (12,000 km) 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
79~94 lbf·ft [11~13 kgf·m]).Disc brake pads should be inspected
for wear whenever tires are rotated.
Information
Tires that are asymmetrical or direc-
tional can only be installed on the
wheel in one direction. The outside
and inside of an asymmetrical tire is
not easily distinguishable. Pay careful
attention to the markings on the side-
walls of the tires, noting the "outside"
marking and also the rotating direc-
tion before installing them on the
vehicle.
i
Do not use the compact spare
tire for tire rotation.
Do not mix bias ply and radial
ply tires 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 3 psi to the standard tire pressure specification if colder temperatures are expect-
ed soon.
Tires typically loose 1psi (7kPa) for every 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 prop-
er level. (Air inflation per altitude : +2.4 psi/1 mile)
NOTICE
When replacing tires, use the same type, size, brand, construction and tread pattern originally supplied with
the vehicle.
Using tires of a different size can damage the related parts or not work properly.
