Air conditioning
All HYUNDAI Air Conditioning
Systems are filled with environmen-
tally friendly R-1234yf refrigerant.
1. Start the engine.
2. Push the air conditioning button.
3. Set the mode to the Face Levelmode.
4. Set the air intake control to the recirculated air position. However,
prolonged operation of the recircu-
lated air position will excessively
dry the air. In this case, change the
air position.
5. Adjust the fan speed control and temperature control to maintain
maximum comfort.
When maximum cooling is desired,
set the temperature control to the
extreme left position then set the fan
speed control to the highest speed. When using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic
when outside temperatures are
high. Air conditioning system
operation can cause engine over-
heating. Continue to use the blow-
er fan, but turn the air condition-
ing system off if the engine tem-
perature gauge indicates engine
overheating.
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 the
recirculated air to the fresh outside
air position.
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 win-
dows and sunroof closed.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance.

ABS is an electronic braking system
that helps prevent a braking skid.
ABS allows the driver to steer and
brake at the same time.
Using ABS
To obtain the maximum benefit from
your ABS in an emergency situation,
do not attempt to modulate your
brake pressure and do not try to
pump your brakes. Depress your
brake pedal as hard as possible.
When you apply your brakes under
conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This is
normal and it means your ABS is
active.
ABS does not reduce the time or dis-
tance it takes to stop the vehicle.
Always maintain a safe distance from
the vehicle in front of you.
ABS will not prevent a skid that
results from sudden changes in
direction, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather con-
ditions.ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing wheel movement can still cause
your vehicle to veer into oncoming
traffic or off the road.
On loose or uneven road surfaces,
operation of the anti-lock brake sys-
tem may result in a longer stopping
distance than for vehicles equipped
with a conventional brake system.
The ABS warning light ( ) will stay
on for several seconds after the igni-
tion switch is in the ON position.
During that time, the ABS will go
through self-diagnosis and the light
will go off if everything is normal. If
the light stays on, you may have a
problem with your ABS. Contact an
authorized HYUNDAI dealer as soon
as possible(Continued)
Drive your vehicle at reduced
speeds during the following
conditions:
Rough, gravel or snow-cov-
ered roads.
On roads where the road sur-
face is pitted or has different
surface height.
Tire chains are installed on
your vehicle.
The safety features of an ABS
or ESC equipped vehicle should
not be tested by high speed
driving or cornering. This could
endanger the safety of yourself
or others.

The Blind Spot Detection System
(BSD) uses a radar sensor to alert
the driver.
It senses the rear side territory of the
vehicle and provides an indication to
the driver if it detects an object
approaching from these areas.(1) BSD (Blind Spot Detection)
The warning range depends on
your vehicle speed. However, if
your vehicle is much faster than
the other vehicle, the system will
not warn you.
(2) LCA (Lane Change Assist) If the system detects a vehicle
approaching you at high speed,
the system will warn you.
(3) RCTA (Rear Cross Traffic Alert) If the radar detects an approach-
ing vehicle from the left and right
side as your vehicle moves rear-
ward, the system will warn you.

Blind spot area
Closing at high speed
Always check the road condi-
tion while driving for unex-
pected situations even
though the Blind Spot
Detection System (BSD) is
operating.
The Blind Spot Detection
System (BSD) is a supplemen-
tal system to assist you. Do
not solely rely on the system
and always pay attention and
drive safely.
The Blind Spot Detection
System (BSD) is not a substi-
tute for proper and safe driv-
ing. Always drive safely and
use caution when changing
lanes or backing the vehicle
up. The Blind Spot Detection
System (BSD) may not detect
every object alongside the
vehicle.
