Chapter 5.ECONOMICAL and SAFE OPERA-
TION of Hybrid system
Drive smoothly. Accelerate at a
moderate rate and maintain a
steady cruising speed. Do not
make "jack-rabbit" starts. Do not
race between stoplights.
Avoid heavy traffic whenever pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear out.
The regenerative brake generates
energy when the vehicle deceler-
ates.
When the hybrid battery power is
low, the hybrid system automatical-
ly recharges the hybrid battery.
When the engine is running with
the shift lever in N (Neutral), the
hybrid system cannot generate
electricity. The hybrid battery can-
not recharge with the shift lever in N
(Neutral).

According to the hybrid system
gauge area, the "EV" indicator comes
on or off.
- "EV" indicator ON : Vehicle is driven
using the electric motor or the
petrol engine is stopped.
- "EV" indicator OFF : Vehicle is driv-
en using the petrol engine.Hybrid Battery SOC
(State of Charge) Gauge
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the "0 or 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 "0 or L (Low)" level, we rec-
ommend the vehicle be checked by an
authorised HYUNDAI dealer.

When the vehicle is paint baked,
do not bake over 30 minutes in
70°C or 20 minutes in 80°C
degree.
Do not wash the engine compart-
ment, using water. Water may
cause an electric shock and dam-
age the electronic components.
NOTICE
Never use the package mod-
ules (high voltage battery,
inverter and converter) for any
other purpose.
Do not use an unauthorised
battery charger to charge the
high voltage battery. Doing so
may result in death or serious
injury.
Never locate the high voltage
system near or in a fire.
Never drill into or strike the
package module. Otherwise, it
may be damaged. An electric
shock may occur, resulting in
serious injury or death.
WARNING
Never assemble or disassemble
the high voltage battery system.
If you assemble or disassem-
ble the high voltage battery
system, the durability and per-
formance of the vehicle may be
damaged.
When you want to check the
high voltage battery system,
have the vehicle checked and
inspected by an authorised
HYUNDAI dealer.
Do not touch the high voltage
battery and high voltage cable
connected to motor (orange
colour). Severe burns and elec-
tric shock may occur. For your
safety, do not touch the cover
of electronic components and
electronic cable. Do not remove
the cover of electronic compo-
nents and electronic cable. In
particular, never touch the high
voltage battery system when
the hybrid system in operation.
It may result in death or serious
injury.
WARNING
This hybrid vehicle uses the
hybrid battery system inverter
and converter to generate high
voltage. High voltage in the
hybrid battery system is very
dangerous and may cause
severe burns and electric
shock. This may result in seri-
ous injury or death.
For your safety, never touch,
replace, disassemble or remove
the hybrid battery system
including components, cables
and connectors. Severe burns
or electric shock may result in
serious injury or death when
you fail to follow this warning.
When the hybrid battery sys-
tem operates, the hybrid bat-
tery system can be hot. Always
be careful because burns or
electric shock may be caused
by high voltage.

Introduction
NOTICE indicates a situation
which, if not avoided, could result
in vehicle damage.
Unleaded
Your new vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane
Number) 91 or higher. (Do not use
methanol blended fuels)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as min-
imise exhaust emissions and spark
plug fouling.NEVER USE LEADED FUEL.
The use of leaded fuel is detrimen-
tal to the catalytic converter and
will damage the engine control
system’s oxygen sensor and
affect emission control.
Never add any fuel system clean-
ing agents to the fuel tank other
than what has been specified (We
recommend that you consult an
authorised HYUNDAI dealer for
details.)
NOTICE
NOTICE
Do not "top off" after the noz-
zle automatically shuts off
when refuelling.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
WARNING
CAUTION indicates a hazardous
situation which, if not avoided,
could result in minor or moder-
ate injury.

Safety system of your vehicle
SRS warning light
The SRS (Supplement Restraint
System) air bag warning light on the
instrument panel displays the air bag
symbol depicted in the illustration. The
system checks the air bag electrical
system for malfunctions. The light indi-
cates that there is a potential problem
with your air bag system.During a moderate to severe frontal
collision, sensors will detect the vehi-
cle’s rapid deceleration. If the rate of
deceleration is high enough, the con-
trol unit will inflate the front air bags,
at the time and with the force needed.
The front air bags help protect the driv-
er and front passenger by responding
to frontal impacts in which seat belts
alone cannot provide adequate
restraint. When needed, the side air
bags help provide protection in the
event of a side impact or rollover by
supporting the side upper body area.
Air bags are activated (able to inflate
if necessary) only when the ignition
switch is in the ON position.
Air bags inflate in the event of certain
frontal or side collisions to help pro-
tect the occupants from serious
physical injury.
There is no single speed at which the
air bags will inflate. Generally, air bags
are designed to inflate based upon
the severity of a collision and its direc-
tion. These two factors determine
whether the sensors produce an elec-
tronic deployment/inflation signal. If your SRS malfunctions, the
air bag may not inflate properly
during an accident increasing
the risk of serious injury or
death.
If any of the following condi-
tions occur, your SRS is mal-
functioning:
The light does not turn on for
approximately six seconds
when the ignition switch is in
the ON position.
The light stays on after illumi-
nating for approximately six
seconds.
The light comes on whilst the
vehicle is in motion.
The light blinks when the
engine is running.
We recommend that an autho-
rised HYUNDAI dealer inspect
the SRS as soon as possible if
any of these conditions occur.
