WIPER BLADES
Blade inspection
Commercial hot waxes applied by
automatic car washes have been
known to make the windshield diffi-
cult to clean.Contamination of either the wind-
shield or the wiper blades with for-
eign matter can reduce the effective-
ness of the windshield wipers.
Common sources of contamination
are insects, tree sap, and hot wax
treatments used by some commer-
cial car washes. If the blades are not
wiping properly, clean both the win-
dow and the blades with a good
cleaner or mild detergent, and rinse
thoroughly with clean water.
Blade replacement
When the wipers no longer clean
adequately, the blades may be worn
or cracked, and require replacement.
To prevent damage to the wiper arms
or other components, do not attempt
to move the wipers manually.
The use of a non-specified wiper
blade could result in wiper malfunc-
tion and failure.
1JBA5122CAUTION - Wiper blades
To prevent damage to the wiper
blades, do not use gasoline,
kerosene, paint thinner, or other
solvents on or near them.

BATTERY (PLUG-IN HYBRID)
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 electrolyte from
the battery immediately with a
solution of water and baking soda.
If the vehicle is not going to be
used for an extended time, discon-
nect the battery cables.Always read the following
instructions carefully when
handling a battery.
If any electrolyte gets into
your eyes, flush your eyes
with clean water for at least
15 minutes and get immedi-
ate medical attention.
If electrolyte gets on your
skin, thoroughly wash the
contacted area. If you feel
pain or burning sensation,
get medical attention imme-
diately.
An inappropriately disposed
battery can be harmful to the
environment and human
health. Dispose the battery
according to your local law(s)
or regulation.
The battery contains lead. Do
not dispose of it after use.
Please return the battery to
an authorized Kia dealer to
be recycled.
Never attempt to recharge the bat-
tery when the battery cables are con-
nected.
WARNING- Risk of
explosion
Keep lit cigarettes and
all other flames or
sparks away from the
battery.
The battery contains
hydrogen -- a highly
combustible gas which
will explode if it comes
in contact with a flame or
spark.
Keep batteries out of the
reach of children
because batteries con-
tain highly corrosive
SULFURIC ACID and
electrolytes. Do not
allow battery acid to
contact your skin, eyes,
clothing or paint finish.
Wear eye protection
when charging or work-
ing near a battery.
Always provide ventila-
tion when working in an
enclosed space.

✽
✽
NOTICE
If you connect unauthorized elec-
tronic devices to the battery, the bat-
tery may be discharged. Never use
unauthorized devices.
Recharging the battery
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged
in a short time (because, for exam-
ple, the headlamps or interior
lamps were left on while the vehi-
cle was not in use), recharge it by
slow charging (trickle) for 10 hours.
If the battery gradually discharges
because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours.WARNING- Risk of elec-
trocution
Never touch the electrical igni-
tion system while the vehicle is
running. This system works
with high voltage which can
shock you.
WARNING- Recharging
Battery
Never attempt to recharge the
battery when the battery cables
are connected.
WARNING- Battery lead
compound
Battery posts, terminals, and
related accessories contain
lead and lead compounds.
Wash hands after handling.

741
Maintenance
When recharging the battery,
observe the following precautions:
The battery must be removed from
the vehicle and placed in an area
with good ventilation.
Do not allow cigarettes, sparks, or
flame near the battery.
Watch the battery during charging,
and stop or reduce the charging
rate if the battery cells begin
gassing (boiling) violently or if the
temperature of the electrolyte of
any cell exceeds 49°C (120°F).
Wear eye protection when check-
ing the battery during charging.
Disconnect the battery charger in
the following order.
1. Turn off the battery charger main
switch.
2. Unhook the negative clamp from
the negative battery terminal.
3. Unhook the positive clamp from
the positive battery terminal. Before performing maintenance or
recharging the battery, turn off all
accessories and stop the engine.
The negative battery cable must be
removed first and installed last
when the battery is disconnected.Reset items
The following items should be reset
after the battery has been dis-
charged or the battery has been dis-
connected.

TIRES AND WHEELS
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
Recommended cold tire infla-
tion pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than
1.6 km (1 mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure
refer to “Tires and wheels” in chapter
8.All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.
WARNING - Tire underin-
flation
Inflate your tires consistent with
the instructions provided in this
manual. Severe underinflation
(70 kPa (10 psi) or more) can
lead to severe heat build-up,
causing blowouts, tread separa-
tion and other tire failures that
can result in the loss of vehicle
control. This risk is much higher
on hot days and when driving
for long periods at high speeds.
ODE086006L

Maintenance
Underinflation also results in
excessive wear, poor handling and
reduced fuel economy. Wheel
deformation also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, have it checked by an
authorized Kia dealer.
Overinflation produces a harsh
ride, excessive wear at the center
of the tire tread, and a greater pos-
sibility of damage from road haz-
ards.
Warm tires normally exceed rec-
ommended cold tire pressures by
28 to 41 kPa (4 to 6 psi). Do not
release air from warm tires to
adjust the pressure or the tires will
be underinflated.
Be sure to reinstall the tire inflation
valve caps. Without the valve cap,
dirt or moisture could get into the
valve core and cause air leakage. If
a valve cap is missing, install a
new one as soon as possible.Tire pressure
Always observe the following:
Check tire pressure when the tires
are cold. (After vehicle has been
parked for at least three hours or
hasn't been driven more than 1.6
km (1 mile) since startup.)
Check the pressure of your spare
tire each time you check the pres-
sure of other tires.
Never overload your vehicle. Be
careful not to overload a vehicle
luggage rack if your vehicle is
equipped with one.
Checking tire inflation pres-
sure
Check your tires once a month or
more.
Also, check the tire pressure of the
spare tire.
How to check
Use a good quality gauge to check
tire pressure. You cannot tell if your
tires are properly inflated simply by
looking at them. Radial tires may
look properly inflated even when
they're underinflated.
Check the tire's inflation pressure
when the tires are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven no
more than 1.6 km (1 mile).
WARNING - Tire Inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control and potential injury.
