Air bag non-inflation conditions
OTM030015OTM030015
In certain low-speed collisions the air
bags may not deploy. The air bags are
designed not to deploy in such cases
because they may not provide benefits
beyond the protection of the seat belts.
OTM030016OTM030016
Front air bags are not designed to inflate
in rear collisions, because occupants
are moved backward by the force of the
impact. In this case, inflated air bags
would not provide any additional benefit.
OTM030017OTM030017
Front air bags may not inflate in side
impact collisions, because occupants
move in the direction of the collision,
and thus in side impacts, front air bag
deployment would not provide additional
occupant protection.
However, side and curtain air bags
and front center air bag may inflate
depending on the severity of impact.
OTM030034OTM030034
In an angled collision, the force of impact
may direct the occupants in a direction
where the air bags would not be able to
provide any additional benefit, and thus
the sensors may not deploy any air bags.

Seats & Safety System

OTM030018OTM030018
Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing it
to “ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this “underride” situation
because deceleration forces that are
detected by sensors may be significantly
reduced by such “underride” collisions.
OTM030041OTM030041
Front air bags may not inflate in
rollover accidents because front air bag
deployment would not provide additional
occupant protection.
However, the side and curtain air bags
and front center air bag may inflate in a
rollover situation, when it is detected by
the rollover sensor.
OTM030019OTM030019
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.

CAUTION
Take the following precautions to
maintain optimal performance of the
detecting sensor:
• Never disassemble the detecting
sensor or sensor assembly, or apply
any impact on it.
• If the detecting sensors have been
replaced or repaired, have your
vehicle inspected by an authorized
HYUNDAI dealer.
• Never install any accessories or
stickers on the front windshield, or
tint the front windshield.
• Pay extreme caution to keep the
front view camera dry.
• Never place any reflective objects
(for example, white paper, mirror)
over the dashboard. Any light
reflection may prevent the system
from functioning properly.
• Do not place any objects near the
front windshield or install any
accessories on the front windshield.
It can affect the performance of the
defogging and defrosting function
of the climate control system, which
may prevent the Driver Assistance
systems from operating.
• Do not apply license plate frame or
objects, such as a bumper sticker,
film or a bumper guard, near the
front radar cover.
• Always keep the front radar and
cover clean and free of dirt and
debris.
Use only a soft cloth to wash the
vehicle. Do not spray pressurized
water directly on the sensor or
sensor cover.• If unnecessary force has been
applied to the radar or around the
radar, Forward Collision-Avoidance
Assist may not properly operate
even though a warning message
does not appear on the cluster.
Have the vehicle be inspected by an
authorized HYUNDAI dealer.
• Use only genuine parts to repair or
replace a damaged front radar cover.
Do not apply paint to the front radar
cover.

CAUTION
Take the following precautions to
maintain optimal performance of the
detecting sensor:
• Never disassemble the rear corner
radar or radar assembly, or apply any
impact on it.
• If there is impact on the rear corner
radar or near the radar, even though
the warning message does not
appear on the cluster, Blind-Spot
Safety system may not operate
properly. Have the system be
inspected by an authorized HYUNDAI
dealer.
• If the rear corner radars have
been replaced or repaired, have
the vehicle be inspected by an
authorized HYUNDAI dealer.
• Use only genuine parts to repair the
rear bumper where the rear corner
radar is located.
• Do not apply license plate frame or
objects, such as a bumper sticker,
film or a bumper guard near the rear
corner radar.
• The system may not work properly
if the bumper has been replaced, or
the surroundings of the rear corner
radar has been damaged or paint has
been applied.
• If a trailer, carrier, etc., is installed,
it may adversely affect the
performance of the rear corner radar
or the system may not operate.
For more details on the precautions
of the front view camera, refer to
“Forward Collision-Avoidance Assist
(FCA)” section in chapter 7.

Blind-Spot Safety
With the engine on, select ‘Driver
Assistance
Ÿ Blind-Spot Safety’ from the
Settings menu to set whether or not to
use each function.
- If ‘Active Assist’ is selected, the
system will warn the driver with a
warning message, an audible warning
and braking assist will be applied
depending on the collision risk levels.
- If ‘Warning Only’ is selected, the
system will warn the driver with a
warning message and an audible
warning depending on the collision
risk levels. Braking will not be assisted.
- If ‘Off’ is selected, the system will turn
off.

WARNING
• Forward/Reverse Parking Distance
Warning is a supplemental system.
The operation of the system can be
affected by several factors (including
environmental conditions). It is the
responsibility of the driver to always
check the front and rear views before
and while parking.
• Your new vehicle warranty does not
cover any accidents or damage to
the vehicle due to the malfunction of
Forward/Reverse Parking Distance
Warning.
• Pay close attention when driving
near objects, pedestrians, and
especially children. Some objects
may not be detected by the
ultrasonic sensors, due to the objects
distance, size or material, all of
which can limit the effectiveness of
the sensor.
Limitations of the system
• Forward/Reverse Parking Distance
Warning may not operate normally
when:
- Moisture is frozen to the sensor
- Sensor is covered with foreign
material, such as snow or water
(The system will operate normally
when such foreign material are
removed.)
- The weather is extremely hot or cold
- The sensor or sensor assembly is
disassembled
- The surface of the sensor has been
subjected to a hard impact
- The surface of the sensor has been
scratched with a sharp object
- The sensors or its surrounding
area is directly sprayed with high
pressure washer• Forward/Reverse Parking Distance
Warning may malfunction when:
- Heavy rain or water spray is present
- Water flows on the surface of the
sensor
- Affected by another vehicle’s
sensors
- The sensor is covered with snow
- Driving on uneven road, gravel
roads or bushes
- Objects that generates ultrasonic
waves are near the sensor
- Installing the license plate
differently from the original location
- The vehicle bumper height or
ultrasonic sensor installation has
been modified
- Attaching equipments or
accessories around the ultrasonic
sensors
• The following objects may not be
detected:
- Sharp or slim objects, such as ropes,
chains or small poles.
- Objects, which tend to absorb
sensor frequency, such as clothes,
spongy material or snow.
- Objects smaller than 40 in. (100 cm)
in length and narrower than 6 in. (14
cm) in diameter.
- Pedestrians, animals or objects
that are very close to the ultrasonic
sensors
• Parking Distance Warning Indicators
may be displayed differently from
the actual detected location when
the obstacle is located between the
sensors.
• Parking Distance Warning indicator
may not occur sequentially depending
on vehicle speed or obstacle shape.
• If Forward/Reverse Parking Distance
Warning needs repair, have the
system be inspected by an authorized
HYUNDAI dealer.
