2019 HYUNDAI SONATA HYBRID battery capacity

H45
Information
Gradual capacity reduction of the
high voltage battery.
The high voltage Battery capacity
gradually reduces with time and use.
This is natural characteristic of the
high voltage batteries. The extent at
which capacity is reduced changes
drastically depending on the environ-
ment(ambient temperature, etc.) and
usage conditions such as how the vehi-
cle is driven and how the high voltage
battery is charged. Reduction of the
high voltage battery capacity is not
covered under warranty.
Safety Plug
i
OLFHQ014005K
Never touch the safety plug. The
safety plug is attached to high
voltage hybrid battery system.
Touching the safety plug will
result in death or serious injury.
Service personnel should follow
procedures in service manual.
DANGER
(Continued)
Do not drop water or liquid on
to HPCU, HSG, motor and
fuses. The hybrid system com-
ponents are covered. If you
drop water or liquid on to
hybrid system compone nts, it
may result in electric shock.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
serious 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.

Rear Seats
Folding the rear seat (if equipped)
The rear seatbacks can be folded to
facilitate carrying long items or toincrease the luggage capacity of the
vehicle.
To fold down the rear seatback:
1. Set the front seatback to theupright position and if necessary,
slide the front seat forward.
2. Lower the rear head restraints to the lowest position.
Never allow passengers to sit
on top of the folded down
seatback while the vehicle is
moving. This is not a properseating position and no seat
belts are available for use.This could result in serious
injury or death in case of an
accident or sudden stop.
Objects carried on the folded
down seatback should not
extend higher than the top of
the front seatbacks. This
could allow cargo to slide for-
ward and cause injury or dam-
age during sudden stops.
(Continued)
(Continued)

Do not put objects in the cen-
ter lower part of rear seats.
This could block the battery
cooling duct causing batterydegradation. Do not put objects on the left
side of rear seat. This could
block the battery cooling duct
causing battery degradation.

To prevent damage to the Power Outlets :
Use the power outlet only whenthe engine is running and
remove the accessory plug after
use. Using the accessory plug
for prolonged periods of timewith the engine off could cause
the battery to discharge.
Only use 12V electric acces- sories which are less than 180 W
in electric capacity.
Adjust the air-conditioner or heater to the lowest operating
level when using the power out-let.
Close the cover when not in use.
Some electronic devices can cause electronic interference
when plugged into a vehicle’s
power outlet. These devices may
cause excessive audio staticand malfunctions in other elec-
tronic systems or devices used
in your vehicle.
(Continued)(Continued)
Push the plug in as far as it will
go. If good contact is not made,
the plug may overheat and the
fuse may blow.
Plug in battery equipped electri- cal/electronic devices with
reverse current protection. The
current from the battery may
flow into the vehicle’s electri-
cal/electronic system and causesystem malfunction.
NOTICE
Avoid electrical shocks. Do not
place your fingers or foreign
objects (pin, etc.) into a power
outlet or touch the power outletwith a wet hand.

Maintenance
FFUU SSEE SS
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not
work, first check the driver’s side
fuse panel. Before replacing a blown
fuse, turn the engine and all switches
off, and then disconnect the negative
battery cable. Always replace a
blown fuse with one of the same rat-ing.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized
HYUNDAI dealer. Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and fusible link for higher
amperage ratings.i

OLF074075 NEVER replace a fuse with any-
thing but another fuse of thesame rating.
A higher capacity fuse could
cause damage and possibly
cause a fire.
Do not install a wire or alu-
minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
possibly a fire.
