To charge a cellular phone
The wireless cellular phone charging
system charges only the Qi-enabled
cellular phones (
). Read the label on
the cellular phone accessory cover or
visit your cellular phone manufacturer’s
website to check whether your cellular
phone supports the Qi technology.
The wireless charging process starts
when you put a Qi-enabled cellular
phone on the wireless charging unit.
1. Remove other items, including the
smart key, from the wireless charging
unit. If not, the wireless charging
process may be interrupted. Place
the cellular phone on the center of
charging pad.
2. You can turn ON or OFF the wireless
charging function in the User Settings
mode on the instrument cluster. For
further information, refer to the “LCD
Display Modes” in chapter 4.If your cellular phone is not charging:
- Slightly change the position of the
cellular phone on the charging pad.
- Make sure the indicator light is orange.
The ERROR symbol will blink/flash for
10seconds and turn off if there is a
malfunction in the wireless charging
system.
In this case, temporarily stop the
charging process, re-attempt to
wirelessly charge your cellular phone
and then check the charging status
again.
The system warns you with a message
on the LCD display if the cellular phone
is still on the wireless charging unit after
the engine is turned OFF and the front
door is opened.
For some manufacturers’ cellular
phones, the system may not warn you
even though the cellular phone is left on
the wireless charging unit. This is due
to the particular characteristic of the
cellular phone and not a malfunction of
the wireless charging.
CAUTION
To prevent liquid from damaging
the wireless cellular phone charging
system in your vehicle, be sure not to
spill liquid over the pad when charging
your cellular phone.

3. Enter or confirm the passkey to
confirm the connection.
• If the passkey input screen is
displayed on the Bluetooth device
screen, enter the passkey ‘0000’
which is displayed on the system
screen.
• If the 6-digit passkey is displayed
on the Bluetooth device screen,
ensure that the Bluetooth passkey
displayed on the Bluetooth device
is the same as the passkey on the
system screen and confirm the
connection from the device.
NOTICE
• The screen image in this manual is an
example. Check your system screen
for the exact vehicle name and
Bluetooth device name.
• The default passkey is ‘0000’.
• It may take a while for the system
to connect with the device after
you permit the system to access the
device. When a connection is made,
the Bluetooth status icon appears at
the top of the screen.
• You can change the permission
settings via the mobile phone’s
Bluetooth settings menu. For more
information, refer to your mobile
phone’s user guide.
• To register a new device, repeat
steps 1 to 3.
• If you use the automatic Bluetooth
connection function, a call may be
switched to the vehicle’s Handsfree
when you are taking on the phone
near the vehicle while the vehicle’s
engine is on. If you do not want the
system to connect with the device
automatically, deactivate Bluetooth
on your device.
• When a device is connected to the
system via Bluetooth, the device’s
battery may discharge faster.
Connecting a paired device
To use a Bluetooth device on your
system, connect the paired device to the
system. Your system can connect with
only one device at a time.

[PHONE] button, and then select
Phone settings X Paired devices.
• If there is no connected device,
press the Call/Answer button on the
steering wheel.
2. Turn the [TUNE] knob to select the
device to connect, and then press the
knob.
• If another device is already
connected to your system,
disconnect it. Select the connected
device to disconnect.
NOTICE
• If a connection ends because a
device is out of the connection
range or a device error occurs,
the connection will be restored
automatically when the device
enters the connection range or when
the error is cleared.
• Depending on auto connection
priority, connection to a device may
take time.

WARNING
Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and
death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows
immediately. Exposure to CO can cause unconsciousness and death by asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the
oil or for any other purpose. If you hear a change in the sound of the exhaust or if you
drive over something that strikes the underneath side of the vehicle, we recommend
that the exhaust system be checked as soon as possible by an authorized HYUNDAI
dealer.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous
practice. Run the engine only long enough to start the engine and to move the vehicle
out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the
vehicle , be sure to do so only in an open area with the air intake set at “Fresh” and
fan control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air intakes
located in front of the windshield clear of snow, ice, leaves, or other obstructions.
If you must drive with the tailgate/trunk open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at “Fresh”, the air flow control at “Floor” or “Face”, and the
fan control set to high.

Driving your vehicle
• The dual clutch transmission
incorporates a dry-type dual clutch
mechanism, which allows for better
acceleration performance and
increased fuel efficiency while driving.
But it differs from a conventional
automatic transmission because
it does not incorporate a torque
converter. 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 vibration can be
felt as the transmission shaft speed is
matched with the engine shaft speed.
This is a normal 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 launching the vehicle
from a stop or when traveling at low,
stop-and-go vehicle 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 correct gear.
This is a normal condition.
• 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 accelerator
pedal quickly, you may feel engine
braking before the transmission
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 vehicle may not
be smooth when accelerating at low
speed. During this break-in period, the
shift quality and performance of your
new vehicle is continuously optimized.
WARNING
To reduce the risk of serious injury or
death:
• ALWAYS check the surrounding
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
ignition switch in the LOCK/OFF
position. Unexpected and sudden
vehicle movement can occur if these
precautions are not followed.
• Do not use aggressive engine braking
(shifting from a higher gear to a lower
gear) on slippery roads. This could
cause the tires to slip and may result
in an accident.
