THEFT-ALARM SYSTEM
This system helps to protect your vehicle
and valuables. The horn will sound and
the hazard warning lights will blink
continuously if any of the following
occur:
-A door is opened without using the
remote key or smart key.
-The trunk is opened without using the
remote key or smart key.
-The engine hood is opened.
The alarm continues for 30 seconds, then
the system resets. To turn off the alarm,
unlock the doors with the remote key or

Once the security system is set, opening
any door, the trunk, or the hood without
using the remote key or smart key will
cause the alarm to activate.
The Theft Alarm System will not set if the
hood, the trunk, or any door is not fully
closed. If the system will not set, check
the hood, the trunk, or the doors are fully
closed.
Do not attempt to alter this system or
add other devices to it.
Information
• Do not lock the doors until all
passengers have left the vehicle. If the
remaining passenger leaves the vehicle
when the system is armed, the alarm
will be activated.
• If the vehicle is not disarmed with the

• Before closing the hood, ensure
all obstructions are removed from
around the hood opening.
• Always double check to be sure that
the hood is firmly latched before
driving away. Check there is no
hood open warning light or message
displayed on the instrument cluster.
Driving with the hood opened may
cause a total loss of visibility, which
might result in an accident.
• Do not move the vehicle with the
hood in the raised position, as vision
is obstructed, which might result in
an accident, and the hood could fall
or be damaged.

Closing the fuel filler door
1. To install the fuel tank cap, turn it
clockwise until it “Clicks”.
2. Close the fuel filler door until it is
latched securely.
Tighten the cap until it clicks one time,
otherwise the Check Engine (
) light will illuminate.
NOTICE
There may be an intermittent noise
near the refueling hole while the engine
is idling if the fuel cap is not closed
securely. This occurs normally with the
OBD system.
NOTICE
When refueling on unlevel ground,
the fuel gauge may not point to the F
position.
It is not a malfunction. If you move your
vehicle to a level ground, the fuel gauge
will move to the full position.
WARNING
Gasoline is highly flammable and
explosive. Failure to follow these
guidelines may result in SERIOUS
INJURY or DEATH:
• Read and follow all warnings posted
at the gas station.
• Before refueling, note the location of
the Emergency Gasoline Shut-Off, if
available, at the gas station.
• Before touching the fuel nozzle, you
should eliminate the potential build-
up of static electricity by touching
a metal part of the vehicle, a safe
distance away from the fuel filler
neck, nozzle, or other gas source,
with your bare hand.
• Do not use cellular phones while
refueling. Electric current and/or
electronic interference from cellular
phones can potentially ignite fuel
vapors and cause a fire.
• 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.

authorized HYUNDAI dealer according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
the system should be checked at an
authorized HYUNDAI dealer.
Information
• Replace the filter according to the
Maintenance Schedule.
• If the car is being driven in severe
conditions such as dusty, rough
roads, more frequent cabin air filter
inspections and changes are required.

WARNING
To reduce the risk of serious injury or
death:
• ALWAYS check the surrounding
areas near your vehicle for people,
especially children, before shifting a
vehicle into D (Drive) or R (Reverse).
• Before leaving the driver’s seat,
always make sure the shift lever
is in the P (Park) position, then set
the parking brake, and place the
ignition switch in the LOCK/OFF
position. Unexpected and sudden
vehicle movement can occur if these
precautions are not followed.
• When using Manual Shift Mode, do
not use engine braking (shifting from
a high gear to lower gear) rapidly on
slippery roads. The vehicle may slip
causing an accident.
• To avoid damage to your transaxle,
do not try to accelerate in R (Reverse)
or any forward gear position with the
brakes on.
• When stopped on slope, do not hold
the vehicle with accelerator pedal.
Use the service brake or the parking
brake. •
The dual clutch transmission can be
thought of as an automatically shifting
manual transmission. It gives the
driving feel of a manual transmission,
yet provides the ease of a fully
automatic transmission.
• When D (Drive) is selected, the
transmission will automatically
shift through the gears similar to a
conventional automatic transmission.
Unlike a traditional automatic
transmission, the gear shifting can
sometimes be felt and heard as the
actuators engage the clutches and the
gears are selected.
• The dual clutch transmission adopts
a dry-type dual clutch, which is
different from the torque converter of
the automatic transmission. It shows
better acceleration performance
and increased fuel efficiency while
driving but initial launch might be
little bit slower than the automatic
transmission.
As a result, gear shifts are sometimes
more noticeable than a conventional
automatic transmission and a light
vibration during launching can be felt
as the transmission speed. This is a
normal condition of the dual clutch
transmission.
• The dry-type clutch transfers torque
more directly and provides a direct
drive feeling which may feel different
from a conventional automatic
transmission. This may be more
noticeable when launching the vehicle
from a stop or when traveling at low,
stop-and-go vehicle speeds.
• When rapidly accelerating at a low
vehicle speed, the engine rpm may
increase highly depending on the
vehicle’s driving condition.
• For smooth launch uphill, press
down the accelerator pedal smoothly
depending on the current conditions.
