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

This manual contains important safety information and instructions intended to familiarize you with your vehicle's con-
trols and safety features so you can safely operate your vehicle.

mended that all service and maintenance on your car be performed by an authorized HYUNDAI dealer. HYUNDAI deal-

Safety system of your vehicle
Pre-tensioner seat belt
(Driver and front passenger)
Your vehicle is equipped with driver's
and front passenger's Pre-tensioner
Seat Belts (Retractor Pretensioner
and Emergency Fastening Device
System). The purpose of the pre-ten-
sioner is to make sure the seat belts
fit tightly against the occupant's body
in certain frontal or side collision(s).
The Emergency Fastening Device
System may be activated in certain
crashes where the frontal collision(s)
is severe enough, together with the air
bags.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 occu-
pant's body.
(1) Retractor Pretensioner
The purpose of the retractor pre-
tensioner is to make sure that the
shoulder belts fit in tightly against
the occupant's upper body in cer-
tain frontal or side collision(s).
(2) Emergency Fastening Device
System
The purpose of the Emergency
Fastening Device System is to
make sure that the pelvis belts fit
in tightly against the occupant’s
lower body in certain frontal colli-
sion(s).
If the system senses excessive ten-
sion on the driver or passenger's
seat belt when the pre-tensioner sys-
tem activates, the load limiter inside
the retractor pre-tensioner will
release some of the pressure on the
affected seat belt.
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 pro-
tect you properly in an acci-
dent.
Do not place anything near the
buckle. This may adversely
affect the buckle and cause it
to function improperly.
Always replace your pre-ten-
sioners 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 assem-
blies.

Safety system of your vehicle
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 colli-
sion energy is absorbed by the vehi-
cle 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 illumi-
nate when the POWER button is in
the ON position, or continuously
remains on, have your vehicle imme-
diately 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.To reduce the risk of serious
injury or death, take the follow-
ing precautions:
Do not attempt to modify or
disconnect the SRS compo-
nents or wiring, including the
addition of any kind of badges
to the pad covers or modifica-
tions to the body structure.
Do not place objects over or
near the air bag modules on
the steering wheel, instrument
panel, or the front passen-
ger’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 sys-
tem.
Always have inflated air bags
replaced by an authorized
HYUNDAI dealer.

Warning and Indicator lights
Information
Make sure that all warning lights are
OFF after starting the vehicle. If any
light is still ON, this indicates a situa-
tion that needs attention.
Ready Indicator
This indicator illuminates :
When the vehicle is ready to be driven.
- ON : Normal driving is possible.
- OFF : Normal driving is not possible,
or a problem has occurred.
- Blinking : Emergency driving.
When the ready indicator goes OFF
or blinks, there is a problem with the
system. In this case, have your vehi-
cle inspected by an authorized
HYUNDAI dealer.
Service Warning Light
This warning light illuminates :
When the POWER button is in the
ON position.
- It illuminates for approximately 3
seconds and then goes off.
When there is a problem with relat-
ed parts of the fuel cell electric
vehicle control system, such as
sensors, etc.
When the warning light illuminates
while driving, or does not go OFF
after starting the vehicle, have your
vehicle inspected by an authorized
HYUNDAI dealer.
Power Down Warning
Light
This warning light illuminates :
When the vehicle power should be
limited due to a malfunction with
fuel cell stack.
If the warning light continuously
remains on when the vehicle is in
"READY" state, or comes on dur-
ing driving, this indicates that there
may be a malfunction with the fuel
cell stack. If this occurs, we recom-

If the vehicle is being driven in
severe conditions such as dusty or
rough roads and/or if transporting
pets or occupants smoke inside the
vehicle, then more frequent cabin air
filter inspections and changes are
required.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
reduces the performance of the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized HYUNDAI dealer.
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage
to the compressor and abnormal
system operation may occur.The air conditioning system should
be serviced by an authorized
HYUNDAI dealer.
Air Conditioning refrigerant label
The actual Air Conditioning refriger-
ant label in the vehicle may differ
from the illustration.
Each symbols and specification on
air conditioning refrigerant label
means as below :
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri-
cant
Refer to chapter 8 for more detail
location of the air conditioning refrig-
erant label.
NOTICE
ODH043366
■Example
Because the refrigerant
is mildly inflammable at
very high pressure, the
air conditioning system
should only be serv-
iced by trained and cer-
tified technicians. It is
important that the cor-
rect type and amount of oil and
refrigerant is used.Otherwise, it
may cause damage to the vehi-
cle and personal injury.
