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.
• The wireless charging process may
temporarily stop, when temperature
abnormally increases inside the
wireless cellular phone charging
system. Stop the charging cellular
phone and wait until temperature falls
to a certain level.
• The wireless charging process may
temporarily stop when there is any
metallic item, such as a coin, between
the wireless cellular phone charging
system and the cellular phone.
• When charging some cellular phones
with a self-protection feature, the
wireless charging speed may decrease
and the wireless charging may stop.
• If the cellular phone has a thick cover,
the wireless charging may not be
possible. •
If the cellular phone is not completely
contacting the charging pad, wireless
charging may not operate properly.
• Some magnetic items like credit
cards, phone cards or rail tickets may
be damaged if left with the cellular
phone during the charging process.
• When any cellular phone without
a wireless charging function or a
metallic object is placed on the
charging pad, a small noise may
sound. This small sound is due to the
vehicle discerning compatibility of 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.
Information
This device complies with part 15 of the
FCC Rules.
Operation is subject to the following two
conditions:
1. This device may not cause harmful
interference, and

D (Drive)
This is the normal driving position. The
transmission will automatically shift
through a 6-gear sequence, providing
the best fuel economy and power.
To start the vehicle forward, push the D
(Drive) button by depressing the brake
pedal with the engine ON. Then depress
the accelerator pedal smoothly.
For extra power when passing another
vehicle or driving uphill, depress the
accelerator fully. The transmission will
automatically downshift to the next
lower gear (or gears, as appropriate).
When the vehicle is stopped in D (Drive)
position, if you open the driver's door
with the seat belt unfastened, the gear is
shifted to P (Park) position automatically.
However when the vehicle moves in D
(Drive) position, if you open the driver's
door with the seat belt unfastened, the
gear may not shift to P (Park) position
automatically to protect the automatic
transmission.
Shift-lock system
For your safety, the automatic
transmission has a shift-lock system
which prevents shifting the gear from
P (Park) or N (Neutral) to R (Reverse)
or D (Drive) unless the brake pedal is
depressed.
To shift the gear from P (Park) or N
(Neutral) to R (Reverse) or D (Drive):
1. Depress and hold the brake pedal.
2. Start the engine.
3. Depress the brake pedal and push the
R (Reverse) or D (Drive) button.
