Safety system of your vehicle
2
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.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 "under-
ride" situation because deceleration
forces that are detected by sensors
may be significantly reduced by such
“underride” collisions.Front air bags may not inflate in
rollover accidents because front air
bag deployment would not provide
additional occupant protection.
Information
The side and/or curtain air bags may
inflate when the vehicle is rolled over
by a side impact collision, if the vehi-
cle is equipped with side and/or cur-
tain air bags.

Driving your vehicle
When driving in stop-and-go traffic,
and a stopped vehicle in front of you
merges out of the lane, the AEB sys-
tem may not immediately detect the
new vehicle that is now in front of
you. In this case, you must maintain
a safe braking distance, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance.- Detecting the vehicle in front of you
If the vehicle in front of you has cargo
that extends rearward from the cab,
or when the vehicle in front of you
has higher ground clearance, addi-
tional special attention is required.
The AEB system may not be able to
detect the cargo extending from the
vehicle. In these instances, you must
maintain a safe braking distance
from the rearmost object, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain distance.
Detecting pedestrians
(if equipped)
The sensor may be limited when:
• The pedestrian is not fully detected
by the camera recognition system,
for example, if the pedestrian is
leaning over or is not fully walking
upright
• The pedestrian is moving very
quickly or appears abruptly in the
camera detection area
• The pedestrian is wearing clothing
that easily blends into the back-
ground, making it difficult to be
detected by the camera recogni-
tion system
• It is difficult to detect and distin-
guish the pedestrian from other
objects in the surroundings, for
example, when there is a group of
pedestrians or a large crowd
• There is an item similar to a per-
son’s body structure
• The pedestrian is small
• The pedestrian has impaired
mobility
• The sensor recognition is limited

• The radar sensor or camera is
blocked with a foreign object or
debris
• Inclement weather such as heavy
rain or snow obscures the field of
view of the radar sensor or camera
• The outside lighting is too bright
(e.g. when driving in bright sunlight
or in sun glare) or too dark (e.g.
when driving on a dark rural road
at night)
• When light coming from a street
light or an oncoming vehicle is
reflected on a wet road surface
such as a puddle in the road
• The field of view in front is
obstructed by sun glare
• The windshield glass is fogged up;
a clear view of the road is obstruct-
ed
• The adverse road conditions cause
excessive vehicle vibrations while
driving
Information
In some instances, the AEB system
may be cancelled when subjected to
electromagnetic interference.
i
•Do not use the Autonomous
Emergency Braking system
when towing a vehicle.
Application of the AEB sys-
tem while towing may
adversely affect the safety of
your vehicle or the towing
vehicle.
•Use extreme caution when the
vehicle in front of you has
cargo that extends rearward
from the cab, or when the
vehicle in front of you has
higher ground clearance.
•The AEB system is designed
to detect and monitor the
vehicle ahead or detect a
pedestrian in the roadway
through radar signals and
camera recognition. It is not
designed to detect bicycles,
motorcycles, or smaller
wheeled objects such as lug-
gage bags, shopping carts, or
strollers.

•Never try to test the operation
of the AEB system. Doing so
may cause severe injury or
death.
WARNING
When you replace the wind-
shield glass, bumper or
radar/camera, we recommend
that you take your vehicle to an
authorized HYUNDAI dealer and
have the system checked for
calibration.

What to do in an emergency
6
When driving with the compact spare
tire mounted to your vehicle:
• Check the tire pressure after
installing the compact spare tire.
The compact spare tire should be
inflated to 420 kPa (60 psi).
• Do not take this vehicle through an
automatic car wash while the com-
pact spare tire is installed.
• Do not use the compact spare tire
on any other vehicle because this
tire has been designed especially
for your vehicle.
• The compact spare tire's tread life
is shorter than a regular tire.
Inspect your compact spare tire
regularly and replace worn com-
pact spare tires with the same size
and design, mounted on the same
wheel.
• Do not use more than one compact
spare tire at a time.
• Do not tow a trailer while the com-
pact spare tire is installed.When the original tire and wheel
are repaired and reinstalled on the
vehicle, the lug nut torque must be
set correctly. The correct lug nut
tightening torque is 11~13 kgf.m
(79~94 lbf.ft).NOTICE
To prevent damaging the com-
pact spare tire and your vehicle:
•Drive slowly enough for the
road conditions to avoid all
hazards, such as a potholes
or debris.
•Avoid driving over obstacles.
The compact spare tire diame-
ter is smaller than the diame-
ter of a conventional tire and
reduces the ground clearance
approximately 25 mm (1 inch).
•Do not use tire chains on the
compact spare tire. Because
of the smaller size, a tire chain
will not fit properly.
•Do not use the compact spare
tire on any other wheels, nor
should standard tires, snow
tires, wheel covers or trim
rings be used with the com-
pact spare wheel.
