You should refill the inverter coolant.
Park with engine On to charge
battery
OOSHQ019013L
This message is displayed when the
hybrid battery power (SOC) level is low.

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 “If the 12 Volt Battery
Is Discharged” 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 “If the 12 Volt Battery
Is Discharged” 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.

RECOMMENDED LUBRICANTS AND CAPACITIES
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.

that you use genuine brake fluid that conform to specifications. (Standard : SAE J1704
DOT-4 LV, ISO4925 CLASS-6 and FMVSS 116 DOT-4)

CAUTION
Always be sure to clean the area around
any filler plug, drain plug, or dipstick
before checking or draining any
lubricant. This is especially important
in dusty or sandy areas and when the
vehicle is used on unpaved roads.
Cleaning the plug and dipstick areas
will prevent dirt and grit from entering
the engine and other mechanisms that
could be damaged.Engine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operating (engine start and engine oil
flowability). Lower viscosity engine oils
can provide better fuel economy and
cold weather performance, however,
higher viscosity engine oils are required
for satisfactory lubrication in hot
weather.
Using oils of any viscosity other than
those recommended could result in
engine damage.
When choosing an oil, consider the
range of temperature your vehicle will be
operated in before the next oil change.
Proceed to select the recommended oil
viscosity from the chart.

*1 : Requires grade engine oil. If a
lower grade engine oil(mineral oil including Semi-synthetic) is used, then the engine oil
and oil filter must be replaced as indicated severe maintenance condition.
An engine oil displaying this American Petroleum Institute(API)
Certification Mark conforms to the International Lubricant Specification
Advisory Committee (ILSAC). It is recommended to only use engine oils
that uphold this API Certification Mark.
