Information
 When using the air conditioning sys- tem, monitor the temperature gauge
closely while 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, air conditioning
should only be used with the win-
dows closed.Air conditioning system operation
tips
If the vehicle has been parked indirect sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
Use air conditioning to reduce humidity and moisture inside the
vehicle on rainy or humid days.
During air conditioning system operation, you may occasionallynotice a slight change in enginespeed 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 passenger side
of the vehicle. This is a normal sys-
tem operation characteristic. 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.

Power outlet (if equipped)
The power outlet is designed to pro-
vide power for mobile telephones or
other devices designed to operate
with vehicle electrical systems. The
devices should draw less than 180
W(Watt) with the engine running.To prevent damage to the PowerOutlets :
Use the power outlet only when
the engine is running and remove
the accessory plug after use.
Using the accessory plug for pro-
longed periods of time with the
engine off could cause the battery
to discharge.
Only use 12V electric accessories which are less than 180 W(Watt) 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 staticand malfunctions in other elec-
tronic 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 causesystem malfunction.
NOTICE

Avoid electrical shocks. Do not
place your fingers or foreign
objects (pin, etc.) into a power
outlet or touch the power outletwith a wet hand.

When rapidly accelerating from alower vehicle speed, the engine
rpm may increase dramatically asa result of clutch slip as the dual
clutch transmission selects the cor-
rect gear. This is a normal condi-tion.
When accelerating from a stop on an incline, press the accelerator
smoothly and gradually to avoid
any shudder feeling or jerkiness.
When traveling at a lower vehicle speed, if you release the accelera-
tor pedal quickly, you may feel
engine braking before the trans-
mission changes gears. This
engine braking feeling is similar to
operating a manual transmission at
low speed. When driving downhill, you may
wish to move the gear shift lever to
Manual Shift mode and downshift
to a lower gear in order to control
your speed without using the brake
pedal excessively.
When you turn the vehicle on and off, you may hear clicking soundsas the system goes through a self
test. This is a normal sound for the
dual clutch transmission.
To hold the vehicle on a hill usethe foot brake or the parking
brake. If the vehicle is held by
applying the accelerator pedal
on a hill the clutch and trans-
mission will be overheated
resulting in damage.
At this time, a warning message "Steep grade! Press brakepedal" will appear on the LCD
display and you may feel a vibra-tion.

If you need to use the shift-lock
release, we recommend that the sys-
tem be inspected by an authorized
HYUNDAI dealer immediately.
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 pedaldepressed.
Never move the shift lever into P (Park) when the vehicle is inmotion.
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, butconsistent 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 transmis-
sion in P (Park) to keep the vehicle
from moving.
When you stay in the vehicle
with the engine running, becareful 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 exhaustsystem components.
Do not stop or park over flam-
mable materials, such as dry
grass, paper or leaves. They
may ignite and cause a fire.

Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the engine is not running or the
vehicle is turned off while driving, the
power assist for the brakes will not
work. You can still stop your vehicle
by applying greater force to the brake
pedal than typical. The stopping dis-
tance, however, will be longer than
with power brakes.
When the engine is not running, the
reserve brake power is partially
depleted each time the brake pedal
is applied. Do not pump the brake
pedal when the power assist has
been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.
BBRRAA KKIINN GG SS YY SSTT EEMM
Take the following precautions:
Do not drive with your foot resting on the brake pedal.This will create abnormal high
brake temperatures, exces-sive brake lining and pad
wear, and increased stoppingdistances.
When descending down a
long or steep hill, move the
shift lever to Manual Shift
mode and manually downshift
to a lower gear in order to
control your speed without
using the brake pedal exces-
sively. Applying the brakes
continuously will cause the
brakes to overheat and could
result in a temporary loss of
braking performance.
(Continued)
(Continued)
Wet brakes may impair the
vehicle's ability to safely slow
down; the vehicle may alsopull to one side when the
brakes are applied. Applying
the brakes lightly will indicate
whether they have been
affected in this way. Always
test your brakes in this fash-
ion after driving through deep
water. To dry the brakes, light-
ly tap the brake pedal to heatup the brakes while maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at highspeeds until the brakes func-
tion correctly.

Hazardous driving conditions
When hazardous driving elements
are encountered such as water,
snow, ice, mud and sand, take the
bellow suggestions:
Drive cautiously and keep a longerbraking distance.
Avoid abrupt braking or steering.
When your vehicle is stuck in snow, mud, or sand, use second gear.
Accelerate slowly to avoid unnec-
essary wheel spin.
Put sand, rock salt, tire chains or other non-slip materials under the
wheels to provide additional trac-
tion while the vehicle becomes
stuck in ice, snow, or mud.
Rocking the vehicle
If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
front wheels. Then, shift back and
forth between R (Reverse) and a for-
ward gear.
Try to avoid spinning the wheels, and
do not race the engine.
To prevent transmission wear, wait
until the wheels stop spinning before
shifting gears. Release the accelera-tor pedal while shifting, and press
lightly on the accelerator pedal while
the transmission is in gear. Slowly
spinning the wheels in forward and
reverse directions causes a rocking
motion that may free the vehicle.

Downshifting with an automatic transmission while driving on
slippery surfaces can cause an
accident. The sudden change intire speed could cause the tires
to skid. Be careful when down-
shifting on slippery surfaces.
WARNING
If the vehicle is stuck and
excessive wheel spin occurs,the temperature in the tires can
increase very quickly. If the tires
become damaged, a tire blow
out or tire explosion can occur.
This condition is dangerous -
you and others may be injured.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle.
If you attempt to free the vehi-
cle, the vehicle can overheat
quickly, possibly causing an
engine compartment fire or
other damage. Try to avoid spin-
ning the wheels as much as
possible to prevent overheating
of either the tires or the engine.
DO NOT allow the vehicle to
spin the wheels above 56 km/h(35 mph).
