service Hyundai Ioniq Hybrid 2019 Service Manual

When you do not use the vehiclefor a long time in a low tempera-
ture area, disconnect the battery
and keep it indoors.
Always charge the battery fully to prevent battery case damage
in low temperature areas.
For Best Battery Service
Keep the battery securely mount-ed.
Keep the battery top clean and dry.
Keep the terminals and connec- tions clean, tight, and coated with
petroleum jelly or terminal grease.
Rinse any spilled acid from the bat- tery immediately with a solution of
water and baking soda.

CALIFORNIA PROPOSITION 65
WARNING
Battery posts, terminals, and
related accessories contain
lead and lead compounds,
chemicals known to the State of
California to cause cancer, birth
defects and reproductive harm.
Batteries also contain other
chemicals known to the State of
California to cause cancer.
Wash hands after handling.
WARNING
Always follow these instruc-
tions when recharging your
vehicle's battery to avoid the
risk of SERIOUS INJURY or
DEATH from explosions or acid
burns:
Before performing mainte-
nance or recharging the bat-
tery, turn off all accessories
and place the Engine Start/
Stop button in the OFF posi-
tion.
Keep all flames, sparks, or
smoking materials away from
the battery.
Always work outdoors or in an
area with plenty of ventilation.
Wear eye protection when
checking the battery during
charging.
The battery must be removed
from the vehicle and placed in
a well ventilated area. (Continued)

Maintenance
Compact spare tire replacement(if equipped)
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mounted
on the same compact spare tire
wheel. The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire.
Wheel Replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
Tire Traction
Tire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires should be
replaced when the tread depth is at
least 1/16 inch (1.6 mm). To reduce
the possibility of losing control, slow
down whenever there is rain, snow or
ice on the road.
(Continued)
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, HYUNDAI recommends
that tires be replaced after six
(6) years of normal service.
When replacing tires (or
wheels), it is recommended to
replace the two front or two
rear tires (or wheels) as a pair.
Replacing just one tire can
seriously affect your vehicle's
handling. If only replacing one
pair of tires, it is recommend-
ed to install the pair of new
tires on the rear axle.
Heat caused by hot climates
or frequent high loading con-
ditions can accelerate the
aging process. Failure to fol-
low this warning may cause
sudden tire failure, which
could lead to a loss of vehicle
control resulting in an acci-
dent.
The original tire should be
repaired or replaced as soon as
possible to avoid failure of the
spare and loss of vehicle con-
trol resulting in an accident. The
compact spare tire is for emer-
gency use only. Do not operate
your vehicle over 50 mph (80
km/h) when using the compact
spare tire.
WARNING

Maintenance
4. Tire ply composition andmaterial
The number of layers or plies of rub-
ber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.
5. Maximum permissible infla-tion pressure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation
pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate.
These grades are molded on the
sidewalls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicle
may vary with respect to grade.

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 exceeding
the Eco-friendly range. 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
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.

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 High Voltage Battery Cooling
Duct
The high-voltage battery cooling duct
is located on the left side of the rear
seats.
i
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.
