e-Handling (Electrically Assisted
Handling Performance)/e-EHA
(Electrically Evasive Handling
Assist)
e-Handling controls the electric motor
while turning around to improve the
handling performance, driving safety,
convenience and ride comfort.
e-EHA connects FCA (Forward Collision
Avoidance Assist) and the electric motor
to provide assists to avoid collision
so that prompt collision avoidance is
available while FCA warning appears.
Ãe-Handling stands for Electrically
Assisted Handling Performance.
Ãe-EHA means Electrically Evasive
Handling Assist.
Operation condition
e-Handling starts to work by identifying
enter or exit condition if the driver
operates the steering wheel over a
certain level when the vehicle speed is
between 40km/h and 120km/h.
e-EHA operates if there is urgent steering
wheel operation while FCA (Forward
Collision Avoidance Assist) warning
appears
Operation cancel
-When ESC operates
-When ABS works
CAUTION
The system does not work under the
following conditions.
-When the ESC operation stop light
is on
-When it does not work due to a
malfunction of electronic device
-When the manual transmission mode
is set
-The gear shift is not in D (Drive)
Information
Please refer to the chapter 6 “Paddle shift
(manual transmission mode) of automatic
transmission (electronic transmission
button)”

Seat belt restraint system
Lap/shoulder belt
OHI038140
To fasten your seat belt:
Pull it out of the retractor and insert the
metal tab (1) into the buckle (2). There
will be an audible “click” when the tab
locks into the buckle.
OHI038137
You should place the lap belt (1) portion
across your hips and the shoulder belt (2)
portion across your chest.
The seat belt automatically adjusts to the
proper length after the lap belt portion
is adjusted manually so that it fits snugly
around your hips. If you lean forward in
a slow, easy motion, the belt will extend
and move with you.
If there is a sudden stop or impact, the
belt will lock into position. It will also lock
if you try to lean forward too quickly.
NOTICE
If you are not able to smoothly pull
enough of the seat belt out from the
retractor, firmly pull the seat belt out
and release it. After release, you will be
able to pull the belt out smoothly.
WARNING
OHI038182L
Improperly positioned seat belts may
increase the risk of serious injury
in an accident. Take the following
precautions when adjusting the seat
belt:
• Position the lap portion of the seat
belt as low as possible across your
hips, not on your waist, so that it
fits snugly. This allows your strong
pelvic bones to absorb the force of
the crash, reducing the chance of
internal injuries.
• Position one arm under the shoulder
belt and the other over the belt, as
shown in the illustration.
• Always position the shoulder belt
anchor into the locked position at the
appropriate height.
• Never position the shoulder belt
across your neck or face.

Do not install a Child Restraint
System on the front passenger seat
OHI039193N
Even though your vehicle is equipped
with the OCS, never install a child
restraint in the front passenger’s seat.
An inflating air bag can forcefully strike a
child or child restraint resulting in serious
or fatal injury.
WARNING
NEVER use a rearward facing Child
Restraint on a seat protected by an
ACTIVE AIRBAG in front of it, DEATH
or SERIOUS INJURY to the CHILD can
occur.
Why didn’t my air bag go off in a
collision?
There are certain types of accidents in
which the air bag would not be expected
to provide additional protection. These
include rear impacts, second or third
collisions in multiple impact accidents,
as well as low speed impacts. Damage to
the vehicle indicates a collision energy
absorption, and is not an indicator of
whether or not an air bag should have
inflated.
Air bag collision sensors
WARNING
To reduce the risk of an air bag
deploying unexpectedly and causing
serious injury or death:
• Do not hit or allow any objects to
impact the locations where air bags
or sensors are installed.
• Do not perform maintenance on or
around the air bag sensors. If the
location or angle of the sensors is
altered, the air bags may deploy
when they should not or may not
deploy when they should.
• Installing bumper guards with non-
genuine Hyundai or non-equivalent
parts may adversely affect the
collision and airbag deployment
performance.
• Press the Engine Start/Stop button to
the OFF or ACC position and wait for
3 minutes when the vehicle is being
towed to prevent inadvertent air bag
deployment.
• We recommend that all air bag
repairs are conducted by an
authorized HYUNDAI dealer.

Seats & Safety System
3-64
ONX4030051
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.
ONX4030053
Front air bags may not inflate in
rollover accidents because front air bag
deployment would not provide additional
occupant protection.
ONX4030052
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.

Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking system. This means you
still have braking on two wheels even if
one of the dual systems should fail.
With only one of the dual systems
working, more than normal pedal travel
and greater pedal pressure is required to
stop the vehicle.
Also, the vehicle will not stop in as short
a distance with only a portion of the
brake system working.
If you experience a malfunction with
the brake system while driving, attempt
to slow your vehicle by coasting or
by using engine braking. You may be
able to reduce your vehicle speed by
manually downshifting to a lower gear.
Use Manual Shift Mode using either the
gear shift lever or the paddle shifters (if
equipped) to shift to a lower gear.
WARNING
Parking Brake & Brake Fluid Warning
Light
Driving the vehicle with a warning light
ON is dangerous. If the Parking Brake
warning light illuminates with the
parking brake released, it indicates that
the brake fluid level is low.
If this occurs, we recommend that
you have the vehicle inspected by an
authorized HYUNDAI dealer.
Regenerative brake warning
light
(yellow)
This warning light illuminates:
When the regenerative brake does not
operate and the brake does not perform
well. This causes the Brake Warning
light (red) and Regenerative Brake
Warning Light (yellow) to illuminate
simultaneously.
If this occurs, drive safely and we
recommend that you have the vehicle
inspected by an authorized HYUNDAI
dealer.
The operation of the brake pedal may
be more difficult than normal and the
braking distance may increase.
Anti-lock Brake System (ABS)
warning light
This warning light illuminates:
• When you set the ignition switch or
the Engine Start/Stop button to the
ON position.
-The ABS warning light illuminates
for about 3 seconds and then goes
off.
• Whenever there is a malfunction with
the ABS.
Note that the hydraulic braking
system will still be operational even
if there is a malfunction with the
ABS. If the ABS warning light remains
illuminated while driving, have the
vehicle inspected by an authorized
HYUNDAI dealer.
