latch (1) inside of the hood center
and lift the hood (2). After it has been
raised about halfway, it will raise
completely by itself. Closing the hood
1. Before closing the hood, check in and
around the engine compartment to
ensure the following:
- Any tools or other loose objects are removed from the engine room area
or hood opening area
- All glove, rags, or other combustible material is removed from the engine
compartment
- All filler caps are tightly and correctly installed
2. Lower the hood halfway (lifted approximately 30 cm (12 inches) from
the closed position) and push down
to securely lock in place. Then double
check to be sure the hood is secure.
If the hood can be raised slightly, it is
not securely locked. Open it again and
close it with more force.
WARNING
• Before closing the hood, ensure
all obstructions are removed from
around the hood opening.
• Always double check to be sure that
the hood is firmly latched before
driving away. Check there is no
hood open warning light or message
displayed on the instrument cluster.
Driving with the hood opened may
cause a total loss of visibility, which
might result in an accident.
• Do not move the vehicle with the
hood in the raised position, as vision
is obstructed, which might result in
an accident, and the hood could fall or be damaged.

WARNING
When the outside temperature is below
freezing, ALWAYS warm the windshield
using the defroster to help prevent
the washer fluid from freezing on the
windshield and obscuring your vision
which could result in an accident and
serious injury or death.
NOTICE
• To prevent possible damage to the
washer pump, do not operate the
washer when the fluid reservoir is
empty.
• To prevent possible damage to the
wipers or windshield, do not operate
the wipers when the windshield is
dry.

Monitor Auto On’ on the user setting
menu, you can choose the Surround
View Monitor system to turn on
automatically in case of the parking alarm sounds.
• If the system is not operating
normally, have the vehicle inspected
by an authorized HYUNDAI dealer.
CAUTION
• Surround View Monitor system is
a parking assist system. Because
the images of the four cameras on
the front, rear, left, and right are
synthesized, the SVM view and
parking guidelines may differ from
the actual vehicle location. So, check
all directions for safety.
• Always keep the rear view camera
lens clean. If the lens is covered with
foreign material, it may adversely
affect camera performance and
Surround View Monitor may not
operate normally. However, do not
use chemical solvents such as strong
detergents containing high alkaline
or volatile organic solvents (gasoline,
acetone etc.). This may damage the
camera lens.

Wireless Cellular Phone
Charging System (if equipped)
ODN8059223
[A]: Indicator light, [B]: Charging pad
On certain models, the vehicle comes
equipped with a wireless cellular phone
charger.
The system is available when all doors
are closed, and when the ignition switch is ON.
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
the charging pad (
).
2. The indicator light is orange when the cellular phone is charging. The
indicator light turns green when
phone charging is complete.
3. 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 this chapter.
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 indicator light will blink orange for 10
seconds if there is a malfunction in the
wireless charging system.
In this case, temporarily stop the
charging process, and re-attempt to
charge your cellular phone 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.
Information
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.
NOTICE
• The wireless cellular phone charging system may not support certain
cellular phones, which are not
verified for the Qi specification (
).
• When placing your cellular phone on the charging mat, position the
phone in the middle of the mat for
optimal charging performance. If
your cellular phone is off to the side,
the charging rate may be less and in
some cases the cellular phone may
experience higher heat conduction.
• In some cases, the wireless charging may stop temporarily when the
Remote Key or Smart Key is used,
either when starting the vehicle or
locking/unlocking the doors, etc.
• When charging certain cellular phones, the charging indicator
may not change to green when the
cellular phone is fully charged.

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, have the exhaust
system 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 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.
