Control your speed
Excessive speed is a major factor in
crash injuries and deaths. Generally, the
higher the speed, the greater the risk,
but serious injuries can also occur at
lower speeds. Never drive faster than is
safe for current conditions, regardless of
the maximum speed posted.
Keep your vehicle in safe
condition
Having a tire blowout or a mechanical
failure can be extremely hazardous. To
reduce the possibility of such problems,
check your tire pressures and condition
frequently, and perform all regularly
scheduled maintenance.

WARNING
• Do not hit or allow any objects to
impact the locations where air bags
or sensors are installed.
This may cause unexpected air bag
deployment, which could result in
serious personal injury or death.
• If the installation location or angle
of the sensors is altered in any way,
the air bags may deploy when they
should not or they may not deploy
when they should, causing severe
injury or death.
Therefore, do not try to perform
maintenance on or around the air
bag sensors. We recommend that the
system be serviced by an authorized
HYUNDAI dealer.
• Problems may arise if the sensor
installation angles are changed
due to the deformation of the front
bumper and body. We recommend
that the system be serviced by an
authorized HYUNDAI dealer.
• Your vehicle has been designed to
absorb impact and deploy the air
bag(s) in certain collisions. Installing
aftermarket bumper guards or
replacing a bumper with non-
genuine parts may adversely affect
your vehicles collision and air bag
deployment performance.
Air bag inflation conditions
OBC3030027OBC3030027
Front air bags
Front air bags are designed to inflate in
certain frontal collision depending on
the crash severity, speed or angles of
impact of the front collision.
If the vehicle chassis is impacted by
bumps or objects on unimproved roads
or sidewalks, air bags may deploy.
Drive carefully on unimproved roads
or on surfaces not designed for vehicle
traffic to prevent unintended air bag
deployment.

Safety system
OBC3030033OBC3030033
• Air bags may not inflate if the vehicle
collides with objects such as utility
poles or trees, where the point of
impact is concentrated and the
collision energy is absorbed by the
vehicle structure.
SRS Care
The SRS is virtually maintenance-
free and so there are no parts you
can safely service by yourself. If the
SRS air bag warning light does not
illuminate, or continuously remains
on, we recommend that the system be
inspected by an authorized HYUNDAI
dealer.
We recommend that the any work on
the SRS system, such as removing,
installing, repairing, or any work on the
steering wheel, the front passenger’s
panel, front seats and roof rails be
performed by an authorized HYUNDAI
dealer. Improper handling of the SRS
system may result in serious personal
injury.
WARNING
• Modification to SRS components
or wiring, including the addition
of any kind of badges to the pad
covers or modifications to the body
structure, can adversely affect SRS
performance and lead to possible
injury.
• For cleaning the air bag pad covers,
use only a soft, dry cloth or one which
has been moistened with plain water.
Solvents or cleaners could adversely
affect the air bag covers and proper
deployment of the 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.

Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also has a bad
influence on the air conditioning system.
Therefore, if abnormal operation is
found, we recommend that the system
be inspected by an authorized HYUNDAI
dealer.
NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
WARNING
Vehicles equipped with R-134a
Since the refrigerant is
operated at very high
pressure, the air
conditioning system should
only be serviced by trained
and certified technicians.
All refrigerants should be reclaimed
with proper equipment.
Venting refrigerants directly to the
atmosphere is harmful to individuals
and environment. Failure to heed these
warnings can lead to serious injuries.

- About handling the system
• Do not apply excessive force to the
system. Excessive pressure on the
screen may damage the LCD panel or
the touch panel.
• When cleaning the screen or button
panel, make sure to stop the engine
and use a soft, dry cloth. Wiping the
screen or buttons with a rough cloth or
using solvents (alcohol, benzene, paint
thinner, etc.) may scratch or chemically
damage the surface.
• If you attach a liquid-type air freshener
to the fan louvre, the surface of the
louvre may become deformed due to
the flowing air.
• If you want to change the position of
the installed device, please inquire
with your place of purchase or service
maintenance centre. Technical expertise
is required to install or disassemble the
device.
