INTRODUCTION
Congratulations, and thank you for choosing HYUNDAI. We are pleased to welcome
you to the growing number of discerning people who drive HYUNDAIs. We are very
proud of the advanced engineering and high-quality construction of each HYUNDAI

Your Owner’s Manual will introduce you to the features and operation of your new
HYUNDAI. To become familiar with your new HYUNDAI, so that you can fully enjoy it,
read this Owner’s Manual carefully before driving your new vehicle.
This manual contains important safety information and instructions intended to
familiarize you with your vehicle’s controls and safety features so you can safely
operate your vehicle.
This manual also contains information on maintenance designed to enhance safe
operation of the vehicle. It is recommended that all service and maintenance on your
car be performed by an authorized HYUNDAI dealer. HYUNDAI dealers are prepared
to provide high-quality service, maintenance and any other assistance that may be
required.
This Owner’s Manual should be considered a permanent part of your vehicle, and
should be kept in the vehicle so you can refer to it at any time. The manual should stay
with the vehicle if you sell it to provide the next owner with important operating, safety
and maintenance information.

Seats & Safety System

Pre-tensioner seat belt
(Driver and front passenger)
OHI038143L
Your vehicle is equipped with driver’s
and front passenger’s Pre-tensioner
Seat Belts (Retractor Pre-tensioner). The
purpose of the pre-tensioner is to make
sure the seat belts fit tightly against the
occupant’s body in certain frontal or side
collision(s).
When the vehicle stops suddenly, or
if the occupant tries to lean forward
too quickly, the seat belt retractor will
lock into position. In certain frontal or
side collision(s), the pre-tensioner will
activate and pull the seat belt into tighter
contact against the occupant’s body.
If the system senses excessive tension
on the driver or passenger’s seat belt
when the pre-tensioner system activates,
the load limiter inside the retractor
pre-tensioner will release some of the
pressure on the affected seat belt.
WARNING
• Always wear your seat belt and sit
properly in your seat.
• Do not use the seat belt if it is loose
or twisted. A loose or twisted seat
belt will not protect you properly in
an accident.
• Do not place anything near the
buckle. This may adversely affect
the buckle and cause it to function
improperly.
• Always replace your pre-tensioners
after activation or an accident.
• NEVER inspect, service, repair or
replace the pre-tensioners yourself.
This must be done by an authorized
HYUNDAI dealer.
• Do not hit the seat belt assemblies.
WARNING
Do not touch the pre-tensioner seat
belt assemblies for several minutes
after they have been activated. When
the pre-tensioner seat belt mechanism
deploys during a collision, the pre-
tensioners become hot and can burn
you.

Seats & Safety System

ODN8A039088
Front air bags may not inflate in rollover
accidents because air bag deployment
may not provide protection to the
occupants.
However, side and curtain air bags may
inflate when the vehicle is rolled over by a side impact collision.
ODN8A039055
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 there are no parts you can safely
service by yourself. If the SRS air bag
warning light does not illuminate when
the ignition switch is in the ON position,
or continuously remains on, have your
vehicle immediately inspected by an
authorized HYUNDAI dealer.
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 must be performed by an authorized
HYUNDAI dealer. Improper handling of
the SRS system may result in serious
personal injury.
WARNING
To reduce the risk of serious injury or
death, take the following precautions: • Do not attempt to modify or
disconnect the SRS components or
wiring, including the addition of any
kind of badges to the pad covers or
modifications to the body structure.
• Do not place objects over or near
the air bag modules on the steering
wheel, instrument panel, or the front
passenger’s panel above the glove box.
• Clean the air bag pad covers with
a soft cloth moistened with plain
water. Solvents or cleaners could
adversely affect the air bag covers
and proper deployment of the
system.
• Always have inflated air bags
replaced by an authorized HYUNDAI
dealer.
• If components of the air bag system
must be discarded, or if the vehicle
must be scrapped, certain safety
precautions must be observed.
Consult an authorized HYUNDAI
dealer for the necessary information.
Failure to follow these precautions
could increase the risk of personal
injury.
