Gauges
Hybrid System Gauge
The hybrid system gauge indicates
whether the current driving condition
is fuel efficient or not.
• CHARGE :
Shows that the energy made by
the vehicle is being converted
to electrical energy. (Regenerated
energy)
ECO : Shows that the vehicle is being
driven in an Eco-friendly manner.
POWER : Shows that the vehicle is exceed-
ing the Eco-friendly range. According to the hybrid system
gauge area, the “EV” indicator
comes on or off.
- “EV” indicator ON : Vehicle is driv-
en using the electric motor or the
gasoline engine is stopped.
- “EV” indicator OFF : Vehicle is driv- en using the gasoline engine.
Hybrid Battery SOC (State of Charge) Gauge
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 (State of charge)
gauge is near the "L (Low)" level, have
the vehicle checked by an authorized
HYUNDAI dealer.

H6
Check Hybrid system. Do not start
engine.
This warning message illuminates
when the hybrid battery power
(SOC) level is low. A warning chime
will sound until the problem is solved.
You may pull over to a complete stop
with parking brake on hold the accel-
erator Down fully to the floor to attempt
rapid Charge back of the battery at a
controlled Speed. Watch the HEV
Battery Gauge to make Sure it is mov-
ing higher. If not there may be a prob-
lem. In that case, have your vehicle
inspected by An authorized HYUNDAI
dealer.
Stop vehicle and check power supply
This warning message illuminates
when a failure occurs in the power
supply system.
In this case, park the vehicle in a safe
location and tow your vehicle to the
nearest authorized HYUNDAI dealer
and have the vehicle inspected.
Stop vehicle to charge battery
This warning message illuminates
when the hybrid battery power (SOC)
level is low.
In this case, park the vehicle in a
safe location and wait until the hybrid
battery is charged.

H7
Refuel to prevent Hybrid battery
damage
This warning message illuminates
when the fuel tank is nearly empty.
You should refill the fuel tank to pre-
vent hybrid battery damage.
Do not continue to run the vehicle
out of gas thinking that vehicle
can continue to operate in EV
only. it may damage the HEV
Battery.
Refill inverter coolant
This warning message illuminates
when the inverter coolant is nearly
empty.
You should refill the inverter coolant.
Stop vehicle and check brakes
This warning message illuminates
when a failure occurs in the brake
system.
In this case, park the vehicle in a safe
location and tow your vehicle to the

The hybrid system informs the driv-
ers its energy flow in various operat-
ing modes. While driving, the current
energy flow is specified in 11 modes.
Vehicle Stop
The vehicle is stopped.
(No energy flow)
EV Propulsion
Only the motor power is used to drive
the vehicle.

Starting the vehicle
1.Carry the smart key or leave itinside the vehicle.
2.Make sure the parking brake is firmly applied.
3.Place the shift lever in P (Park) with the shift lever in N (Neutral),
you cannot start the vehicle.
4.Depress the brake pedal.
5.Press the Engine Start/Stop but- ton. If the hybrid system starts, the
" " indicator will come on and a
double chime can be heard.
Whether the engine is cold or
warm, it should be started without
depressing the accelerator.
After following the start proce-
dures, “ ” indicator on the
instrument cluster will turn on.
For more information, please check
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 run with the shift lever in N (Neutral), the hybrid sys-
tem cannot generate electricity. The
hybrid battery cannot recharge with
the shift lever in N (Neutral).
Information
In the hybrid system, the engine auto-
matically runs and stops. When the
hybrid system operates, the " "
indicator is illuminated.
In the following situation, the engine
may operate automatically.
- When the engine is ready to run
- When the hybrid battery is beingcharged
- Depending on the temperature con- dition of the hybrid battery
