Information
• When using the air conditioning sys-
tem, monitor the temperature gauge
closely whilst driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine
overheating. Continue to use the
blower fan but turn the air condi-
tioning system off if the temperature
gauge indicates engine overheating.
• When opening the windows in
humid weather, air conditioning
may create water droplets inside the
vehicle. Since excessive water
droplets may cause damage to elec-
trical equipment, the air condition-
ing should only be used with the
windows closed.
Air conditioning system operation
tips
If the vehicle 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.
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.
During air conditioning system
operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
Use the air conditioning system
every month only for a few minutes
to ensure maximum system per-
formance.
When using the air conditioning
system, you may notice clear water
dripping (or even puddling) on the
ground under the vehicle. This is a
normal system operation charac-
teristic. Operating the air conditioning sys-
tem in the recirculated air position
provides maximum cooling, how-
ever, continual operation in this
mode may cause the air inside the
vehicle to become stale.
During cooling operation, you may
occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristic.

maximum comfort.
Information
Your vehicle is filled with R-134a or
R-1234yf according to the regulation
in your country at the time of produc-
tion. You can find out which air condi-
tioning refrigerant is applied to your
vehicle on the label located inside of
the bonnet. Refer to chapter 8 for the
location of the air conditioning refrig-
erant label. The refrigerant system should
only be serviced by trained and
certified technicians to insure
proper and safe operation.
The refrigerant system should
be serviced in a well-ventilated
place.
The air conditioning evaporator
(cooling coil) should never be
repaired or replaced with one
removed from a used or sal-
vaged vehicle and new replace-
ment MAC evaporators should
be certified (and labelled) as
meeting SAE Standard J2842.
Information
• When using the air conditioning sys-
tem, monitor the temperature gauge
closely whilst driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine
overheating. Continue to use the
blower fan but turn the air condi-
tioning system off if the temperature

The devices should draw less than
120 W(Watt) with the engine running.
To prevent damage to the Power
Outlets :
Use the power outlets 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 12V electric acces-
sories which are less than 120W
(Watt) in electric capacity.
Adjust the air-conditioner or
heater to the lowest operating
level when using the power out-
lets.
Close the cover when not in use.
Some electronic devices can
cause electronic interference
when plugged into the vehicle’s
power outlets. These devices
may cause excessive audio stat-
ic 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 electri-
cal/electronic devices with
reverse current protection. The
current from the battery may
flow into the vehicle's electri-
cal/electronic system and cause
system malfunction.
NOTICE
Avoid electrical shocks. Do not
place your fingers or foreign
objects (pin, etc.) into the power
outlets or touch the power out-
lets with a wet hand.
WARNING

5-22
Driving your vehicle
To prevent damage to the engine,
clutch and transmission:
When downshifting from 5th
gear to 4th gear, be careful not
to inadvertently push the shift
lever sideways engaging 2nd
gear. The drastic downshift may
cause the engine speed to
increase to the point that the
tachometer will enter the red-
zone.
Do not downshift more than two
gears at a time or downshift the
gears when the engine is run-
ning at high speed (5,000 RPM
or higher). Such downshifting
may damage the engine, clutch
and the transmission.
Good driving practices
Never take the vehicle out of gear
and coast down a hill. This is
extremely dangerous.
Don't "ride" the brakes. This can
cause the brakes and related parts
to overheat and malfunction.
When you are driving down a long
hill, slow down and shift to a lower
gear. Engine braking will help slow
down the vehicle.
Slow down before shifting to a
lower gear. This will help avoid
over-revving the engine, which can
cause damage.
Slow down when you encounter
cross winds. This gives you much
better control of your vehicle.
Be sure the vehicle is completely
stopped before you shift into R
(Reverse) to prevent damage to
the transmission. 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.
NOTICE
Do not use the engine brake
(shifting from a higher gear to
lower gear) rapidly on slippery
roads. The vehicle may slip
causing an accident.

Ignition key interlock system
(if equipped)
The ignition key cannot be removed
unless the shift lever is in the P
(Park) position.
Parking
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift lever 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.
Good driving practices
Never move the shift lever from P
(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
Never move the shift lever 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 move the shift lever 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.
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 sports 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. When you stay in the vehicle
with the engine running, be
careful not to depress the accel-
erator 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 flam-
mable materials, such as dry
grass, paper or leaves. They
may ignite and cause a fire.
WARNING

5-33
Driving your vehicle
When driving downhill, you may
use Sports Mode and press the
paddle shifters to downshift to a
lower gear in order to control your
speed without using the brake
pedal excessively.
When you turn the engine on and
off, you may hear clicking sounds
as the system goes through a self
test. This is a normal sound for the
Dual clutch transmission.LCD display for transmission

sage
Transmission temperature
gauge
Select trip computer mode on the
LCD display and move to the trans-
mission temperature screen to see
the temperature of the dual clutch
transmission.
Try to drive so that the temperature
gauge does not show high/over-
heat. When the transmission is
overheated, the warning message
will display on the LCD. Follow the
displayed message. The transmission temperature is
displayed in three colours (white,
orange and red) as it increases. (if
equipped with the cluster type B)
An orange temperature gauge is
displayed right before the warning
message appears on the LCD dis-
play. (if equipped)
5Due to transmission failure, you
may not continue to drive and
the position indicator (D, R) on
the cluster will blink. We recom-
mend you to contact an autho-
rised HYUNDAI dealer and have
the system checked.
WARNING Increase (high temperature)
on the transmission tempera-
ture gauge usually appears on
an incline when the vehicle is
stopped for a long time using
accelerator pedal, without
depressing the brake pedal.
To maintain the optimal trans-
mission performance, drive
so that the white gauge is not
exceeded. (if equipped)
