Air conditioning
HYUNDAI Air Conditioning Systems are
filled with R-1234yf refrigerant.
1. Start the engine. Push the air conditioning button.
2. Set the mode to the
position.
3. Set the air intake control to the outside air or recirculated air position.
4. Adjust the fan speed control and temperature control to maintain
maximum comfort.
NOTICE
When using the air conditioning system,
monitor the temperature gauge closely
while driving up hills or in heavy traffic
when outside temperatures are high.
Air conditioning system operation may
cause engine overheating. Continue to
use the fan but turn the air conditioning
system off if the temperature gauge
indicates engine overheating. Air conditioning system operation tips

[
If the v
ehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.

[ After sufficient cooling has been
achieved, switch back from the
recirculated air to the fresh outside air
position.

[ To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the windows
and sunroof closed.

[ Use the air conditioning system every
month for a few minutes to ensure
maximum system performance.

[ If you operate the air conditioner
excessively, the difference between
the temperature of the outside air and
that of the windshield could cause
the outer surface of the windshield to
fog up, causing loss of visibility. In this
case, set the mode selection button to
the
position and set the fan speed
control knob to the lowest speed
setting.

Power Outlet
„Front
OTM050026
„Rear
OTM050031
The power outlet is designed to provide
power for mobile telephones or other
devices designed to operate with vehicle
electrical systems. The devices should
draw less than 180 watts with the engine
running.
WARNING
Avoid electrical shocks. Do not place
your fingers or foreign objects (pin, etc.)
into a power outlet or touch the power
outlet with a wet hand.
CAUTION
To prevent damage to the power
outlets:

[ Use the power outlet only when the
engine is running and remove the
accessory plug after use. Using the
accessory plug for prolonged periods
of time with the engine off could
cause the battery to discharge.

[ Only use 12 volts electric accessories
which are less than 180 watts in
electric capacity.

[ Adjust the air-conditioner or heater
to the lowest operating level when
using the power outlet.

[ Close the cover when not in use.

[ Some electronic devices can
cause electronic interference
when plugged into a vehicle’s
power outlet. These devices may
cause excessive audio static and
malfunctions in other electronic
systems or devices used in your
vehicle.

[ Push the plug in as far as it will go. If
good contact is not made, the plug
may overheat and the fuse may open.

[ Plug in battery equipped electrical/
electronic devices with reverse
current protection. The current
from the battery may flow into the
vehicle’s electrical/electronic system
and cause system malfunction.

Driving Your Vehicle6-14
5. When the message ‘Vehicle will stay in (N). Change gear to cancel’ (or ‘N will
stay engaged when the vehicle is Off’)
appears on the cluster LCD display,
press the Engine Start/Stop button
while depressing the brake pedal.
However, if you open the driver’s or door,
the gear will automatically shift to P
(Park) and the Engine Start/ Stop button
will change to the OFF position.
When the battery is discharged:
You cannot shift the shift button, when
the battery is discharged.
In emergencies, do the following to
move the shift button to N (Neutral) on a
level ground.
1. Connect the battery cables from another vehicle or from another
battery.
For more details, refer to “Jump
Starting” in chapter 8.
2. Release the parking brake with the Engine Start/Stop button in the ON
position.
3. Shift the gear to the N(Neutral) position refer to the “Stay in Neutral
when vehicle is Off” in this chapter.
Parking
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift button into the P (Park)
position, apply the parking brake, and
place the ignition switch in the LOCK/
OFF position. Take the Key with you
when exiting the vehicle.

[The gear is shifted to P (Park) position
automatically for safety under the
following conditions.
- When the driver unfastens the seat belt and opens the driver’s
door in the “Stay in Neutral when
the ignition is in the ON or OFF
condition
- When turning off the engine in the R (Reverse) / D (Drive) or N (Neutral)
position
This is supplemental function for safety.
Always check the P (Park) position is
shifted.
WARNING
When you stay in the vehicle with
the engine running, be careful not to
depress the accelerator pedal for a long
period of time. The engine or exhaust
system may overheat and start a fire.
The exhaust gas and the exhaust system
are very hot. Keep away from the
exhaust system components.
Do not stop or park over flammable
materials, such as dry grass, paper or
leaves. They may ignite and cause a fire.

6-17

[When driving uphill or downhill,
always shift to D (Drive) for driving
forward or shift to R (Reverse) for
driving rearwards. After selecting
D (Drive) or R (Reverse), check the
gear position indicated on the cluster
before driving. If the vehicle moves in
the opposite direction of the selected
gear, the engine may turn off and a
serious accident might occur due to
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.

[ 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 seat belt. 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 t ravel lanes.

[ HYUNDAI recommends you follow all
posted speed limits.
WARNING

[Before leaving the driver's seat,
always make sure the shift button
is in the P (Park) position, set the
parking brake, press the Engine
Start/Stop button to the OFF
position, and take the Smart Key with
you.
Unexpected and sudden vehicle
movement can occur if these
precautions are not followed.

[ Do not drive with the shift button in
N (Neutral). The engine brake will not
work and may lead to an accident.

[ 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.
