• The indicator may differ from the
illustration depending on objects
or sensors status. If the indicator
blinks, we recommend that you
have your vehicle checked by an
authorized HYUNDAI dealer.
• If the audible warning does not
sound or if the buzzer sounds
intermittently when shifting into R
(Reverse) position, this may indi-
cate a malfunction with the
Parking Assist System. If this
occurs, we recommend that you
have your vehicle checked by an
authorized HYUNDAI dealer as
soon as possible.
To turn off the Rear Parking
Assist System (if equipped)
Push the button to turn off the Rear
Parking Assist System. The indicator
light on the button will turn on.
Non-operational conditions of
Parking Assist System
The Rear Parking Assist System

• Moisture is frozen to the sensor.
• The sensor is covered with dirt or
debris such as snow or ice, or the
sensor cover is blocked.
There is a possibility of the Rear
Parking Assist System malfunction
when:
• Driving on uneven road surfaces
such as unpaved roads, gravel,
bumps, or gradient.
• Objects generating excessive noise
such as vehicle horns, loud motor-
cycle engines, or truck air brakes
can interfere with the sensor.
• Heavy rain or water spray is present.
• Wireless transmitters or mobile
phones are present near the sensor.

Key ignition switch
(if equipped)
Illuminated ignition switch
(if equipped)
Whenever the front door is opened,
the ignition switch will illuminate, pro-
vided the ignition switch is not in the
ON position. The light will go off
immediately when the ignition switch
is turned on or go off after about 30
seconds when the door is closed.
•NEVER turn the ignition
switch to the LOCK or ACC
position while the vehicle is in
motion except in an emer-
gency. This will result in
engine turning off and loss of
power assist for the steering
and brake systems. This may
lead to loss of directional con-
trol and braking function,
which could cause an acci-
dent.

WARNING
(Continued)
•Before leaving the driver's
seat, always make sure the
shift lever is in the P (Park)
position, apply the parking
brake, and turn the ignition
switch to the LOCK position.
Unexpected vehicle move-
ment may occur if these pre-
cautions are not followed.

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.
