On certain models, the vehicle comes
equipped with a wireless cellular phone
charger.
The system is available when all doors

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.

Starting the engine
WARNING
• Always wear appropriate shoes when
operating your vehicle.
Unsuitable shoes, such as high heels,
ski boots, sandals, flip-flops, etc.,
may interfere with your ability to use
the brake and accelerator pedals.
• Do not start the vehicle with the
accelerator pedal depressed. The
vehicle can move and lead to an
accident.
• Wait until the engine rpm is normal.
The vehicle may suddenly move if
the brake pedal is released when the
rpm is high.
Information
• The engine will start by pressing the
Engine Start/Stop button, only when
the smart key is in the vehicle.
• Even if the smart key is in the vehicle,
if it is far away from the driver, the
engine may not start.
• When the Engine Start/Stop button
is in the ACC or ON position, if any
door is open, the system checks for the
smart key. If the smart key is not in the
vehicle, the “
” indicator will blink
and the warning "Key not in vehicle"
will come on and if all doors are closed,
the chime will also sound for about
5 seconds. Keep the smart key in the
vehicle when using the ACC position or
if the vehicle engine is ON.
1. Always carry the smart key with you.
2. Make sure the parking brake is
applied.
3. Make sure the gear is in P (Park).
4. Depress the brake pedal.
5. Press the Engine Start/Stop button. If
the vehicle starts, the “” indicator
will come on.
Information
• Do not wait for the engine to warm up
while the vehicle remains stationary.
Start driving at moderate engine
speeds. (Aggressive accelerating and
decelerating should be avoided.)
• Always start the vehicle with your foot
on the brake pedal. Do not depress the
accelerator while starting the vehicle.
Do not rev the engine while warming
it up.
• If ambient temperature is low,
the “
” indicator may remain
illuminated longer than the normal
amount of time.
NOTICE
To prevent damage to the vehicle:
• If the “
” indicator turns off while
you are in motion, do not attempt to
move the shift button to the P (Park)
position.
• Do not push or tow your vehicle to
start the engine.

surroundings of gear shift button.
If this message appears again, have
the vehicle inspected by an authorized
HYUNDAI dealer.

LCD display, when the transmission
or the shift button does not properly
operate in the P (Park) position.
In this case, have the vehicle inspected
by an authorized HYUNDAI dealer.
Check shift controls

Good Driving Practices
• Never shift the gear from P (Park) or
N (Neutral) to any other position with
the accelerator pedal depressed.
• Never shift the gear into P (Park) when
the vehicle is in motion.
• Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive). •
Do not shift the gear to N (Neutral)
when driving. Doing so may result
in an accident because of a loss of
engine braking and the transmission
could be damaged.
• Driving uphill or downhill, always shift
to D (Drive) when driving forward or to
R (Reverse) when driving backwards,
and check the gear position indicated
on the cluster before driving. If you
drive in the opposite direction of the
selected gear, the engine will turn
off and a serious accident might be
occurred due to the degraded brake
performance.
• Do not drive with your foot resting
on the brake pedal. Even light, but
consistent pedal pressure can result
in the brakes overheating, brake wear
and possibly even brake failure.
• When driving in the manual shift
mode, slow down before shifting to a
lower gear. Otherwise, the lower gear
may not be engaged if the engine
rpms are outside of the allowable
range.
• Always apply the parking brake when
leaving the vehicle. Do not depend on
placing the transmission in P (Park) to
keep the vehicle from moving.
• Exercise extreme caution when
driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the drive
wheels to lose traction and may cause
loss of vehicle control resulting in an
accident
• Optimum vehicle performance and
economy is obtained by smoothly
depressing and releasing the
accelerator.

WARNING
To reduce the risk of SERIOUS INJURY
or DEATH:
• ALWAYS wear your seatbelt. In a
collision, an unbelted occupant
is significantly more likely to be
seriously injured or killed than a
properly belted occupant.
• Avoid high speeds when cornering or
turning.
• Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.
• The risk of rollover is greatly
increased if you lose control of your
vehicle at highway speeds.
• Loss of control often occurs if two or
more wheels drop off the roadway
and the driver over steers to reenter
the roadway.
• In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
• HYUNDAI recommends you follow all
posted speed limits.
Information
Kickdown Mechanism (if equipped)
If you depress the accelerator pedal
equipped with Kickdown device beyond
the pressure point, it maximizes the engine
power. You may feel when the Kickdown
equipment starts to work and hear the
sound of Kickdown operation. It is normal
operation, not a failure.

(Manual Shift Mode)
ODN8069009
