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 type, size, brand,
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.
ODN8H019025L
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 has been driven
for less than one mile (1.6 km).
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” in chapter 2.

Tire Replacement
Tread wear indicatorTread wear indicator
OLMB073027
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 2/32 inch (1.6 mm) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the tread surface to
become level with the tread wear
indicators before replacing the tire.
WARNING
To reduce the risk of DEATH or
SERIOUS INJURY:
• Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, and traction.
• Always replace tires with the
same size 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.
• 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, it is
recommended to replace the
two front or two rear tires as a
pair. Replacing just one tire can
seriously affect your vehicle’s
handling. If only replacing one
pair of tires, it is recommended
to install the pair of new tires on
the rear axle.
• Heat caused by hot climates or
frequent high loading conditions
can accelerate the aging process.
Failure to follow this warning
may cause sudden tire failure,
which could lead to a loss of
vehicle control resulting in an
accident.

NOTICE
Using anything but recommended
cleaners and procedures may affect the
fabric’s appearance and fire-resistant
properties.
Leather (if equipped)
• Features of seat leather
- L

eather is made from the outer skin
of an animal, which goes through a
special process to be available for
use. Since it is a natural product,
each part differs in thickness or
density.
Wrinkles may appear as a natural
result of stretching and shrinking
depending on the temperature and
humidity.
- The sea

t is made of stretchable
fabric to improve comfort.
- The parts con

tacting the body are
curved and the side supporting
area is high which provides driving
comfort and stability.
- W

rinkles may appear naturally
from usage. It is not a fault of the
products.
CAUTION
• Wrinkles or abrasions which appear
naturally from usage are not covered
by warranty.
• Belts with metallic accessories,
zippers or keys inside the back
pocket may damage the seat fabric.
• Make sure not to wet the seat. It may
change the nature of natural leather.
• Jeans or clothes which could bleach
may contaminate the surface of the
seat covering fabric. •
Caring for the leather seats
- V
acuum the seat periodically to
remove dust and sand on the seat. It
will prevent abrasion or damage of
the leather and maintain its quality.
- Wipe the na
tural leather seat cover
often with dry or soft cloth.
- U
se of proper leather protector may
prevent abrasion of the cover and
helps maintain the color. Be sure to
read the instructions and consult
a specialist when using leather
coating or protective agent.
- Ligh
t colored (beige, cream beige)
leather is easily contaminated and
the stain is noticeable. Clean the
seats frequently.
- A
void wiping with wet cloth. It may
cause the surface to crack.
• Cleaning the leather seats
- R
emove all contaminations
instantly. Refer to instructions below
for removal of each contaminant.
- Cosme
tic products (sunscreen,
foundation, etc.)
Apply cleansing cream on a cloth
and wipe the contaminated spot.
Wipe off the cream with a wet cloth
and remove water with a dry cloth. - Be verages (coffee, soft drink, etc.)
Apply a small amount of neutral
detergent and wipe until
contaminations do not smear.
- Oil R

emove oil instantly with
absorbable cloth and wipe with
stain remover used only for natural
leather.
- Che

wing gum
Harden the gum with ice and
remove gradually.

Maintenance

1. Crankcase Emission Control System
The positive crankcase ventilation system
is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase. This system supplies
fresh filtered air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh air mixes with blow-by gases,
which then pass through the PCV valve
into the induction system.
2. Evaporative Emission Control System Including Onboard
Refueling Vapor Recovery
(ORVR)
The Evaporative Emission Control System
is designed to prevent fuel vapors from
escaping into the atmosphere. The
ORVR system is designed to allow the
vapors from the fuel tank to be loaded
into a canister while refueling at the gas
station, preventing the escape of fuel
vapors into the atmosphere.
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in the
canister are drawn into the surge tank
through the purge control solenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve
is controlled by the Engine Control
Module (ECM); when the engine coolant
temperature is low during idling, the
PCSV closes so that evaporated fuel
is not taken into the engine. After the
engine warms-up during ordinary
driving, the PCSV opens to introduce
evaporated fuel to the engine.
3. Exhaust Emission Control System
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performance.
When the engine starts or fails to start,
excessive attempts to restart the engine
may cause damage to the emission
system.
Engine exhaust (carbon monoxide)
precautions
• Carbon monoxide can be present
with other exhaust fumes. If you smell
exhaust fumes of any kind in your
vehicle, drive with all the windows
fully open. Have your vehicle checked
and repaired immediately.
WARNING
Engine exhaust gases contain carbon
monoxide (CO). Though colorless and
odorless, it is dangerous and could be
lethal if inhaled. Follow the instructions
on this page to avoid CO poisoning.
WARNING
CALIFORNIA PROPOSITION 65
WARNING
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the
interior furnishings in a vehicle, contain
or emit chemicals known to the State
of California to cause cancer and
birth defects and reproductive harm.
In addition, certain fluids contained
in vehicles and certain products of
component wear contain or emit
chemicals known to the State of
California to cause cancer and birth
defects or other reproductive harm.
