WIPER BLADES
Blade inspection
✽
✽
NOTICE
Commercial hot waxes applied by auto-
matic car washes have been known to
make the windshield difficult to clean.
Contamination of either the windshield or
the wiper blades with foreign matter can
reduce the effectiveness of the wind-
shield wipers. Common sources of con-
tamination are insects, tree sap, and hot
wax treatments used by some commer-
cial car washes. If the blades are not wip-
ing properly, clean both the window and
the blades with a good cleaner or mild
detergent, and rinse thoroughly with
clean water.Blade replacement
When the wipers no longer clean ade-
quately, the blades may be worn or
cracked, and require replacement.
1JBA5122CAUTION
To prevent damage to the wiper
blades, do not use gasoline,
kerosene, paint thinner, or other
solvents on or near them.
CAUTION
To prevent damage to the wiper
arms or other components, do not
attempt to move the wipers manual-
ly.
CAUTION
The use of a non-specified wiper
blade could result in wiper malfunc-
tion and failure.

For best 12V battery service
The 12V battery is in the trunk.
Keep the 12V battery securely mount-
ed.
Keep the 12V battery top clean and
dry.
Keep the terminals and connections
clean, tight, and coated with petroleum
jelly or terminal grease.
Wipe any spilled electrolyte from the
12V battery immediately with a solu-
tion of water and baking soda.
If the vehicle is not going to be used for
an extended time, disconnect the 12V
battery cables.

WARNING- Battery
dangers
Always read the following
instructions carefully when
handling a battery.
Keep lighted cigarettes and
all other flames or sparks
away from the battery.
Hydrogen, a highly com-
bustible gas, is always
present in battery cells and
may explode if ignited.
Keep batteries out of the
reach of children because
batteries contain highly
corrosive SULFURIC ACID.
Do not allow battery acid to
contact your skin, eyes,
clothing or paint finish.
(Continued)
(Continued)
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 a
pain or a burning sensa-
tion, get medical attention
immediately.
Wear eye protection when
charging or working near a
battery. Always provide
ventilation when working in
an enclosed space.
An inappropriately disposed
battery can be harmful to
the environment and human
health. Dispose the battery
according to your local
law(s) or regulation.

Maintenance
12V Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the 12V battery becomes discharged
in a short time (because, for example,
the headlights or interior lights were
left on while the vehicle was not in
use), jump start it from another vehi-
cle’s 12V battery or recharge it by slow
charging (trickle) for 10 hours.
If the 12V battery gradually discharges
because of high electric load while the
vehicle is being used, recharge it at 20-
30A for two hours.CALIFORNIA PROPOSI-
TION 65 WARNING
Battery posts, terminals, and relat-
ed accessories contain lead and
lead compounds, chemicals known
to the State of California to cause
cancer, birth defects and reproduc-
tive harm. Batteries also contain
other chemicals known to the State
of California to cause cancer. Wash
hands after handling.
CAUTION
When you don’t use the vehicle
for a long time in the low temper-
ature, remove the 12V battery and
store it indoors.
Always charge the 12V battery
fully to prevent 12V battery case
damage in low temperatures.
If you connect unauthorized elec-
tronic devices to the 12V battery,
the 12V battery may be dis-
charged. Never use unauthorized
devices.
(Continued)
When lifting a plastic-cased bat-
tery, excessive pressure on the
case may cause battery acid to
leak, resulting in personal injury.
Lift with a battery carrier or with
your hands on opposite corners.
Never attempt to recharge the
battery when the battery cables
are connected.
The electrical ignition system
works with high voltage. Never
touch these components with the
engine running or the engine
start/stop button positioned on.
Failure to follow the above warn-
ings can result in serious bodily
injury or death.

Reset items
Items should be reset after the 12V bat-
tery has been discharged or the 12V bat-
tery has been disconnected.

Audio (See section 4)WARNING
Before performing maintenance
or recharging the 12V battery,
turn off all accessories and stop
the engine.
The negative battery cable must
be removed first and installed
last when the 12V battery is dis-
connected.
Operation related to the 12V bat-
tery should be done in an author-
ized HYUNDAI dealer.
WARNING- Recharging
12V battery
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 charg-
ing, and stop or reduce the charg-
ing rate if the battery cells begin
gassing (boiling) violently or if
the temperature of the electrolyte
of any cell exceeds 120°F (49°C).
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.

Maintenance
CAUTION
Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is
possible. Keep your tire pres-
sures at the proper levels. If a
tire frequently needs refilling,
have it checked by an author-
ized HYUNDAI dealer.
Overinflation produces a
harsh ride, excessive wear at
the center of the tire tread, and
a greater possibility of dam-
age from road hazards.
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 inflation
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
one mile (1.6 km).
Recommended pressures must be
maintained for the best ride, vehicle
handling, and minimum tire wear.
For recommended inflation pressure,
refer to “Tire and wheels” in section
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
Severe underinflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.

Checking tire inflation pressure
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 can not 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 mile (1.6 km).
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.
CAUTION - 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 one mile (1.6
km) since startup.)
Check the pressure of your
spare tire each time you check
the pressure of other tires.
Never overload your vehicle.
Be careful not to overload a
vehicle luggage rack if your
vehicle is equipped with one.
Worn, old tires can cause acci-
dents. If your tread is badly
worn, or if your tires have
been damaged, replace them.
CAUTION
Warm tires normally exceed
recommended cold tire pres-
sures by 4 to 6 psi (28 to 41
kPa). Do not release air from
warm tires to adjust the pres-
sure or the tires will be under-
inflated.
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.
