Battery recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged
over a short time (because, for
example, the headlamps or interior
lights were left on while the vehicle
was not in use), recharge it by slow
charging (trickle) for 10 hours.
• If the battery gradually discharges
because of high electrical load while
the vehicle is being used, recharge it
at 20-30A for two hours.
WARNING
Always follow these instructions when
recharging your vehicle’s battery to
avoid the risk of SERIOUS INJURY or
DEATH from explosions or acid burns:
• Before performing maintenance or
recharging the battery, turn off all
accessories and stop the engine.
• 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.
• Watch the battery during charging,
and stop or reduce the charging
rate if the battery cells begin boiling
violently.
• The negative battery cable must
be removed first and installed last
when the battery is disconnected.
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.
• We recommend that you use
batteries for replacement from an
authorized HYUNDAI dealer.
NOTICE
AGM battery (if equipped)
• Absorbent Glass Matt (AGM)
batteries are maintenance-free
and we recommend that the AGM
battery be serviced by an authorized
HYUNDAI dealer. For charging
your AGM battery, use only fully
automatic battery chargers that
are specially developed for AGM
batteries.
• When replacing the AGM battery,
we recommend that you use parts
for replacement from an authorized
HYUNDAI dealer.
• Do not open or remove the cap on
top of the battery. This may cause
leaks of internal electrolyte that
could result in severe injury.

Maintenance
9-36
WARNING
Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of SERIOUS
INJURY or DEATH, take the
following precautions:
• Inspect your tires monthly for
proper inflation as well as wear
and damage.
• The recommended cold tire
pressure for your vehicle can be
found in this manual and on the
tire label located on the driver’s
side center pillar. Always use a
tire pressure gauge to measure
tire pressure. Tires with too
much or too little pressure wear
unevenly causing poor handling.
• Check the pressure of the
spare every time you check the
pressure of the other tires on
your vehicle.
• Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, or traction.
• ALWAYS replace tires with the
same size, type, construction and
tread pattern as each tire that
was originally supplied with this
vehicle. Using tires and wheels
other than the recommended
sizes could cause unusual
handling characteristics, poor
vehicle control, or negatively
affect your vehicle’s Anti-Lock
Brake System (ABS) resulting in a
serious accident.
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.
ONX4E010022
All specifications (sizes and pressures)
can be found on a label attached to the
driver’s side center pillar.
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 1
mile (1.6km).
Warm tires normally exceed
recommended cold tire pressures
by 4 to 6 psi (28 to 41 kPa). Do not
release air from warm tires to adjust
the pressure or the tires will be
under-inflated. For recommended
inflation pressure, refer to “Tire and
Wheels” section in chapter 2.
TIRES AND WHEELS

Maintenance
9-38
Tire rotation
To equalize tread wear, HYUNDAI
recommends that the tires
be rotated according to the
maintenance schedule or sooner if
irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for
uneven wear and damage. Abnormal
wear is usually caused by incorrect
tire pressure, improper wheel
alignment, out-of-balance wheels,
severe braking or severe cornering.
Look for bumps or bulges in the
tread or side of the tire. Replace
the tire if you find any of these
conditions. Replace the tire if fabric
or cord is visible. After rotation, be
sure to bring the front and rear tire
pressures to specification and check
wheel bolt tightness (proper torque
is 79.6-94.0 lbf.ft [11.0-13.0 kgf.m]).
OHI078078
Disc brake pads should be inspected
for wear whenever tires are rotated.
Information
The outside and inside of the
unsymmetrical tire is distinguishable.
When installing an unsymmetrical
tire, be sure to install the side marked
“outside” face the outside. If the side
marked “inside” is installed on the
outside, it will have a negative effect
on vehicle performance.
WARNING
• Do not use the compact spare
tire for tire rotation.
• Do not mix bias ply and radial ply
tires under any circumstances.
This may cause unusual handling
characteristics that may cause
loss of vehicle control resulting in
an accident.

Tire sidewall labeling
This information identifies and
describes the fundamental
characteristics of the tire and also
provides the tire identification
number (TIN) for safety standard
certification. The TIN can be used to
identify the tire in case of a recall.
OHI078081
1. Manufacturer or brand name
Manufacturer or brand name is
shown.
2. Tire size designation
A tire’s sidewall is marked with a
tire size designation. You will need
this information when selecting
replacement tires for your car.
The following explains what the
letters and numbers in the tire size
designation mean. Example tire size designation:
(These numbers are provided as
an example only; your tire size
designator could vary depending on
your vehicle.)
235/60R18 102H
235 -
Tire width in millimeters.
60 - Aspect ratio. The tire’s section
height as a percentage of its
width.
R - Tire construction code (Radial).
18 - Rim diameter in inches.
102 - Load Index, a numerical code
associated with the maximum
load the tire can carry.
H - Speed Rating Symbol. See the
speed rating chart in this section
for additional information.
Wheel size designation
Wheels are also marked with
important information that you need
if you ever have to replace one. The
following explains what the letters
and numbers in the wheel size
designation mean.
Example wheel size designation:
7.5J X 18
7.5 - Rim width in inches.
J - Rim contour designation.
18 - Rim diameter in inches.

7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and
maximum section width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test course.
For example, a tire graded 150 would
wear one-and-a-half times (1½) as
well on the government 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.
Traction - AA, A, B & C
The traction grades, from highest
to lowest, are AA, A, B and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on
specified government test surfaces
of asphalt and concrete. A tire
marked C may have poor traction
performance.
WARNING
The traction grade assigned to
this tire is based on straight ahead
braking traction tests, and does not
include acceleration, cornering,
hydroplaning, or peak traction
characteristics.
Temperature - A, B & C
The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation
of heat and its ability to dissipate
heat when tested under controlled
conditions on a specified indoor
laboratory test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life,
and excessive temperature can
lead to sudden tire failure. Grades
B and A represent higher levels of
performance on the laboratory test
wheel than the minimum required
by law.

Maintenance
9-44
WARNING
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
under-inflation, over-inflation, or
excessive loading, either separately
or in combination, can cause heat
build-up and possible sudden
tire failure. This may cause loss
of vehicle control resulting in an
accident.
Low aspect ratio tires
(if equipped)
The aspect ratio is lower than 50 on
low aspect ratio tires.
Because low aspect ratio tires are
optimized for handling and braking,
their sidewall is a little stiffer than
a standard tire. Also low aspect
ratio tires tend to be wider and
consequently have a greater contact
patch with the road surface. In some
instances they may generate more
road noise compared with standard
tires.
CAUTION
The side wall of a low aspect ratio
tire is shorter than the normal one.
Thus, the low-aspect wheel and
tire are easily damaged. Follow the
below instructions.
• When driving on a rough road or
driving off a road, be careful not
to damage the tires and wheels.
After driving, inspect the tires
and wheels.
• When passing over a pothole,
speed bump, manhole, or curb
stone, drive the vehicle slowly so
as not to damage the tires and
wheels.
• When there is an impact on a tire,
inspect the tire condition. Or,
you can contact an authorized
HYUNDAI dealer.
• Inspect the tire condition and
pressure every 8,000 miles
(13,000 km) to prevent tire
damage.
• It is difficult to recognize a tire
damage only with your eyes.
When there is a slight hint of a
tire damage, check and replace
the tire to prevent the damage
caused by air leakage.
• When a tire is damaged while
driving on a rough road, off a
road, or over obstacles, such as a
pothole, manhole, or curb stone,
your warranty does not cover the
damage.
• The tire information is specified
on the tire side wall.

rating from a circuit you may not need
for operating the vehicle, such as the
cigarette lighter fuse.
If the headlamps or other electrical
components do not work and the fuses
are undamaged, check the fuse panel
in the engine compartment. If a fuse is
blown, it must be replaced with the same
rating.

We recommend that you consult an
authorized HYUNDAI dealer to replace
most vehicle light bulbs. It is difficult
to replace vehicle light bulbs because
other parts of the vehicle must be
removed before you can get to the bulb.
This is especially true for removing the
headlamp assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to the
vehicle.
WARNING
• Prior to working on a light, depress
the foot brake, shift to P (Park), apply
the parking brake, press the Engine
Start/Stop button to the OFF position
and take the key with you when
leaving the vehicle to avoid sudden
movement of the vehicle and to
prevent possible electric shock.
• Be aware the bulbs may be hot and
may burn your fingers.
NOTICE
Be sure to replace the burned-out bulb
with one of the same wattage rating.
Otherwise, it may cause damage to the
fuse or electrical wiring system.
NOTICE
To prevent damage, do not clean the
headlamp lens with chemical solvents
or strong detergents.
Information - Headlamp
desiccant (if equipped)
This vehicle is equipped with desiccant to
reduce fogging inside the headlamp due
to moisture. The desiccant is consumable
and its performance may change based on
the used period or environment. If fogging
inside the headlamp due to moisture
continues for a long time, we recommend
that you consult an authorized HYUNDAI
dealer.
Information
The headlamp and tail lamp lenses could
appear frosty if the vehicle is washed after
driving or the vehicle is driven at night
in wet weather. This condition is caused
by temperature difference between the
lamp inside and outside and, it does not
indicate a problem with your vehicle.
When moisture condenses in the lamp,
it will be removed after driving with the
headlamp on. The removable level may
differ depending on lamp size, lamp
position and environmental condition.
However, if moisture is not removed, we
recommend that your vehicle is inspected
by an authorized HYUNDAI dealer.
