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.

To prevent damage to the Power Outlets :
Use the power outlet only whenthe engine is running and
remove the accessory plug after
use. Using the accessory plug
for prolonged periods of timewith the engine off could cause
the battery to discharge.
Only use 12V electric acces- sories which are less than 180 W
in electric capacity.
Adjust the air-conditioner or heater to the lowest operating
level when using the power out-let.
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.
(Continued)(Continued)
Push the plug in as far as it will
go. If good contact is not made,
the plug may overheat and the
fuse may blow.
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.

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. 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 controlresulting in an accident
Optimum vehicle performance and economy is obtained by smoothlydepressing and releasing the
accelerator.
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.

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, taking care to keep the
vehicle under control at all times. If
the braking action does not return to
normal, stop as soon as it is safe to
do so and call an authorized
HYUNDAI dealer for assistance.
DO NOT drive with your foot resting
on the brake pedal. Even light, butconstant 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 Engine
Start/Stop button in the OFFposition.
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
below 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 or other non- slip materials under the wheels to
provide additional traction 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).
