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.

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

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.

the object placed on the charging
pad. It does not affect your vehicle or
the cellular phone in any way. Information
If the ignition switch is in the OFF
position, the charging also stops.

Before Entering the Vehicle
• Be sure all windows, outside mirror(s), and outside lights are clean and
unobstructed.
• Remove frost, snow, or ice.
• Visually check the tires for uneven wear and damage.
• Check under the vehicle for any sign of leaks.
• Be sure there are no obstacles behind you if you intend to back up.
Before Starting
• Make sure the hood, the trunk, and the doors are securely closed and
locked.
• Adjust the position of the seat and steering wheel.
• Adjust the inside and side view mirrors.
• Verify all the lights work.
• Fasten your seatbelt. Check that all passengers have fastened their
seatbelts.
• Check the gauges and indicators in the instrument panel and the
messages on the instrument display
when the ignition switch is in the ON
position.
• Check that any items you are carrying are stored properly or fastened down
securely.
WARNING
To reduce the risk of SERIOUS INJURY or
DEATH, take the following precautions:
• ALWAYS wear your seat belt. All
passengers must be properly belted
whenever the vehicle is moving.
For more information, refer to "Seat
Belts" in chapter 3.
• Always drive defensively. Assume
other drivers or pedestrians may be
careless and make mistakes.
• Stay focused on the task of driving.
Driver distraction can cause
accidents.
• Leave plenty of space between you
and the vehicle in front of you.
WARNING
NEVER drink alcohol or take drugs and
drive.
Drinking alcohol or taking drugs and
driving is dangerous and may result in
an accident and SERIOUS INJURY or
DEATH.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Just
one drink can reduce your ability to
respond to changing conditions and
emergencies and your reaction time
gets worse with each additional drink.
Driving while under the influence
of drugs is as dangerous or more
dangerous than driving under the
influence of alcohol.
You are much more likely to have a
serious accident if you drink or take
drugs and drive. If you are drinking or
taking drugs, don't drive. Do not ride
with a driver who has been drinking
or taking drugs. Choose a designated
driver or call a taxi.
