WARNING
If a fire occurs:
• If a small scale fire occurs, use a fire
extinguisher (ABC, BC) that is meant
for electrical fires.
If it is impossible to extinguish
the fire in the early stage, remain
a safe distance from the vehicle
and immediately call your local
fire emergency responders. Also,
advise them that a hybrid vehicle is
involved.
If the fire spreads to the high voltage
battery, large amount of water is
needed to put out the fire.
Using small amount of water or
fire extinguishers not meant for
electrical fires could cause serious
injury or death from electrical
shocks.
• Upon witnessing any sparks, gases,
flames, or fuel leakage of your
vehicle, immediately call emergency
services or contact an authorized
HYUNDAI dealer. Also, advise them
that a hybrid vehicle is involved.
WARNING
When a submersion in water occurs:
When your vehicle is flooded in water, a
high-voltage battery may cause shock
or fires. Thus, turn the hybrid system
OFF, take the key in your possession and
escape to a safe place. Never attempt
physical contact with your flooded
vehicle.
Immediately contact an authorized
HYUNDAI dealer and advise them that a
hybrid vehicle is involved.
When the Hybrid Vehicle Shuts
Off
When the high voltage battery or 12 volt
battery is discharged, or when the fuel
tank is empty, the hybrid system may
not operate while driving. When the
Hybrid system does not operate, do the
following:
1. Gradually reduce the vehicle speed.
Pull over your vehicle off the road in a
safe area.
2. Make sure the shift button is in P (Park).
3. Turn ON the hazard warning flashers.
4. Turn OFF the vehicle, and try to start the hybrid system again, while
depressing the brake pedal and
turning on the ignition switch.
5. When the hybrid system still does not operate, refer to “Jump starting”
section in chapter 8.
Before jump-starting the vehicle,
check the fuel level and the exact
procedure to jump start. For further
details, refer to “Jump starting”
section in chapter 8. When the fuel
level is low, do not attempt to drive
the vehicle only with the battery
power. The high voltage battery may
be discharged, and the hybrid system
will turn OFF.

Vehicle Information, Consumer Information and Reporting Safety Defects2-18
To help achieve proper engine and powertrain performance and durability, use only
lubricants of the proper quality. The correct lubricants also help promote engine
efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.

Pre-tensioner seat belt
ONX4030059
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-tensioner 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 collisions, the pre-
tensioner will activate and pull the seat
belt into tighter contact against the
occupant’s body.
(1) Retractor Pretensioner
The purpose of the retractor pretensioner
is to make sure that the shoulder belts fit
in tightly against the occupant’s upper
body in certain 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
collision(s).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 by
yourself. Have the pre-tensioners
inspected, serviced, repaired or
replaced 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-
tensioner can become hot and can burn
you.
CAUTION
Body work on the front area of the
vehicle may damage the pre-tensioner
seat belt system. Therefore, Have the
system serviced by an authorized
HYUNDAI dealer.

WARNING
To reduce the risk of serious injury or
death from an inflating side air bag and
front center air bag, take the following
precautions:

[Seat belts must be worn at all times
to help keep occupants positioned
properly.

[ Do not allow passengers to lean their
heads or bodies onto doors, put their
arms on the doors, stretch their arms
out of the window, or place objects
between the doors and seats.

[ Hold the steering wheel at the 9
o’clock and 3 o’clock positions, to
minimize the risk of injuries to your
hands and arms.

[ Do not use any accessory seat
covers. This could reduce or prevent
the effectiveness of the system.

[ Do not hang other objects except
clothes. In an accident it may cause
vehicle damage or personal injury
especially when air bag is inflated.
[
Do not place any objects over the
air bag or between the air bag and
yourself. Also, do not attach any
objects around the area the air bag
inflates such as the door, side door
glass, front and rear pillar.

[ Do not place any objects between
the door and the seat. They may
become dangerous projectiles if the
side air bag inflates.

[ Do not install any accessories on the
side or near the side air bags.

[ Do not cause impact to the doors
when the Engine Start/Stop button
is in the ON or START position as this
may cause the side air bags to inflate.

[ If the seat or seat cover is damaged,
have the system serviced by an
authorized HYUNDAI dealer.

Seats & Safety System3-64
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 Engine Start/Stop button 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, and 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.

ONX4EH040008OCN7H040003
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the “L (Low)” level, the vehicle
automatically operates the engine to
charge the battery.
However, if the Service Indicator (
)
and Malfunction Indicator Lamp (MIL)
(
) turn on when the SOC gauge is near
the “L (Low)” level, we recommend the
vehicle be checked by an authorized
HYUNDAI dealer.
NOTICE
Never try to start the vehicle if the fuel
tank is empty. In this condition, the
engine cannot charge the high voltage
battery of the hybrid system. If you
try to start the vehicle when the fuel
is empty, the high voltage battery will
become discharged and be damaged.
