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
fan but turn the air conditioning
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 in
direct 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 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 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.

Driving your vehicle
• The system changes from manual
mode to automatic mode when
- the vehicle speed is lower than 5
km/h (3 mph),
- you depress the accelerator
pedal for more than 5 seconds,
- you pull the [+] paddle shifter for
more than 1 second, or
- you move the shift lever from D
(Drive) to S (Sport) or manual
shift mode (+, -) and then back to
D (Drive).
Information
If the [+] and [-] paddle shifters are
pulled at the same time, gear shift may
not occur.
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.
• 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.
i
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.

Good braking practices Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop
as quickly if the brakes are wet. Wet
brakes may cause the vehicle to pull
to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns
to normal. If the braking action does
not return to normal, stop as soon as
it is safe to do so and we recommend
that you call an authorized HYUNDAI
dealer for assistance.
DO NOT drive with your foot resting
on the brake pedal. Even light, but
constant pedal pressure can result in
the brakes overheating, brake wear,
and possibly even brake failure.
If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the vehicle pointed straight
ahead while you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe location.Keep your foot firmly on the brake
pedal when the vehicle is stopped to
prevent the vehicle from rolling for-
ward.
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Move
the shift lever into the P (Park)
position, then apply the parking
brake, and place the ignition
switch in the LOCK/OFF posi-
tion.
Vehicles parked with the park-
ing brake not applied or not
fully engaged may roll inadver-
tently and may cause injury to
the driver and others. ALWAYS
apply the parking brake before
exiting the vehicle.

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 longer
braking 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.
SPECIAL DRIVING CONDITIONS
Downshifting with an automatic
transmission while driving on
slippery surfaces can cause an
accident. The sudden change in
tire 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).

Information
The ESC system (if equipped) must be
turned OFF before rocking the vehi-
cle.
If you are still stuck after rocking
the vehicle a few times, have the
vehicle pulled out by a tow vehicle
to avoid engine overheating, pos-
sible damage to the transmission,
and tire damage. See "Towing" in
chapter 6.
Smooth cornering
Avoid braking or gear changing in
corners, especially when roads are
wet. Ideally, corners should always
be taken under gentle acceleration.
Driving at night
Night driving presents more hazards
than driving in the daylight. Here are
some important tips to remember:
• Slow down and keep more dis-
tance between you and other vehi-
cles, as it may be more difficult to
see at night, especially in areas
where there may not be any street
lights.
• Adjust your mirrors to reduce the
glare from other drivers' head-
lamps.
• Keep your headlamps clean and
properly aimed. Dirty or improperly
aimed headlamps will make it
much more difficult to see at night.
• Avoid staring directly at the head-
lamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your
eyes to readjust to the darkness.
Driving in the rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or
on slick pavement:
• Slow down and allow extra follow-
ing distance. A heavy rainfall
makes it harder to see and increas-
es the distance needed to stop
your vehicle.
• Turn OFF your Cruise Control. (if
equipped)
• Replace your windshield wiper
blades when they show signs of
streaking or missing areas on the
windshield.
• Be sure your tires have enough
tread. If your tires do not have
enough tread, making a quick stop
on wet pavement can cause a skid
and possibly lead to an accident.
See "Tire Tread" in chapter 7.
• Turn on your headlamps to make it
easier for others to see you.
• Driving too fast through large pud-
dles can affect your brakes. If you
must go through puddles, try to
drive through them slowly.
