Closing the hood
1. Before closing the hood, check the
following:
• All filler caps in engine
compartment must be correctly
installed.
• Gloves, rags or any other
combustible material must
be removed from the engine

• Do not get back into a vehicle
once you have begun refueling.
You can generate a build-up of
static electricity by touching,
rubbing or sliding against any item
or fabric capable of producing
static electricity. Static electricity
discharge can ignite fuel vapors
causing a fire. If you must re-enter
the vehicle, you should once again
eliminate potentially dangerous
static electricity discharge by
touching a metal part of the vehicle,
away from the fuel filler neck, nozzle
or other gasoline source, with your
bare hand.
• When refueling, always move the
shift lever to the P (Park) position,
set the parking brake, and place the
ignition switch to the LOCK/OFF
position.
• Sparks produced by electrical
components related to the engine
can ignite fuel vapors causing a fire.
• When using an approved portable
fuel container, be sure to place the
container on the ground prior to
refueling. Static electricity discharge
from the container can ignite fuel
vapors causing a fire. Once refueling
has begun, contact between your
bare hand and the vehicle should
be maintained until the filling is
complete.
• Use only approved portable plastic
fuel containers designed to carry and
store gasoline.
• Do not use matches or a lighter and
do not smoke or leave a lit cigarette
in your vehicle while at a gas station,
especially during refueling.• Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage.
• If a fire breaks out during refueling,
leave the vicinity of the vehicle, and
immediately contact the manager
of the gas station and then contact
the local fire department. Follow any
safety instructions they provide.
• If pressurized fuel sprays out, it can
cover your clothes or skin and thus
subject you to the risk of fire and
burns. Always remove the fuel cap
carefully and slowly. If the cap is
venting fuel or if you hear a hissing
sound, wait until the condition stops
before completely removing the cap.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.
Information
Make sure to refuel your vehicle according
to the “Fuel Requirements” suggested in
the Introduction chapter.
NOTICE
• Do not spill fuel on the exterior
surfaces of the vehicle. Any type of
fuel spilled on painted surfaces may
damage the paint.
• If the fuel filler cap requires
replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. An
incorrect fuel filler cap can result
in a serious malfunction of the fuel
system or emission control system.

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.
• After sufficient cooling has been
achieved, switch back from
recirculation mode to fresh mode.
• 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.
• During air conditioning system
operation, you may occasionally
notice a slight change in engine speed
as the air conditioning compressor
cycles. This is a normal system
operation characteristic.
• Use the air conditioning system
every month only for a few minutes
to ensure maximum system
performance.
• 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 system
operation characteristic.
• 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.

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.
• When driving uphill or downhill,
always shift to D (Drive) for driving
forward or shift to R (Reverse) for
driving backwards, and check the
gear position indicated on the cluster
before driving. Driving in the opposite
direction of the selected gear, can
lead to a dangerous situation by
shutting off the engine and affecting
the braking 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.
• Do not hold the vehicle on an incline
with the accelerator pedal. This can
cause the transmission to overheat.
Always use the brake pedal or parking
brake.
• 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 travel lanes.
• HYUNDAI recommends you follow all
posted speed limits.
