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

09
9-39
Wheel alignment and tire
balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
NOTICE
Incorrect wheel weights can damage
your vehicle’s aluminum wheels. Use
only approved wheel weights.
Tire replacement
Tread wear indicatorTread wear indicator
OHI078080
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 1/16 inch (1.6mm) of
tread left on the tire. Replace the tire
when this happens.
Do not wait for the band to appear
across the entire tread 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.
• 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.
• 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.
• 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.

-Oil
Remove oil instantly with
absorbable cloth and wipe with
stain remover used only for natural
leather.
-Chewing gum
Harden the gum with ice and
remove gradually.
• Handling prime napa leather (if
equipped)
Try to avoid excessive sunlight and
heat exposure. Excessive sunlight
and heat exposure naturally fades
and dries out napa leather, causing
wrinkles and discoloration. If the napa
leather is wet with liquid, immediately
clean it with lint-free cloth to minimize
damage. Do not scratch the napa
leather surface with a sharp object.
If your napa leather seat is bright
colored, it may be contaminated or
stained from dyed materials such as
jeans.
Interior wooden trim
• Use a wooden furniture protector (e.g.
wax, coating compound) to clean the
interior wooden trim.
• Often wipe the interior wooden
trim with a lint-free, clean cloth to
maintain the unique wooden textures
for a longer period of time.
• If you spill beverage (e.g. water,
coffee) over the interior wooden trim,
immediately wipe it with clean, dry
cloth.
• Sharp objects (e.g. driver, knife),
adhesive materials, or tapes may
damage the interior wooden trim.
• Any strong impacts may damage the
interior wooden trim.
• If the coating finish over the interior
wooden trim is removed, moisture
may damage or change wood traits.
• If the interior wooden trim is
damaged, you may get a splinter
from the wood surface. Therefore,
you should immediately have the
damaged interior wooden trim
replaced by an authorized HYUNDAI
dealer.
Cleaning the seat belt webbing
Clean the belt webbing with any
mild soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the soap.
Do not bleach or re-dye the webbing
because this may weaken the seat belt.
Cleaning the interior window glass
If the interior glass surfaces of the
vehicle become fogged (that is, covered
with an oily, greasy or waxy film), they
should be cleaned with glass cleaner.
Follow the directions on the glass cleaner
container.
NOTICE
Do not scrape or scratch the inside of
the rear window. This may result in
damage to the rear window defroster
grid.

The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
applicable emission regulations. There
are three emission control systems, as
follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to ensure the proper function
of the emission control systems, it
is recommended that you have your
vehicle inspected and maintained
by an authorized HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.
NOTICE
For the Inspection and Maintenance
Test (with Electronic Stability Control
(ESC) system)
• To prevent the vehicle from misfiring
during dynamometer testing, turn
the Electronic Stability Control
(ESC) system off by pressing the ESC
switch (ESC OFF light illuminated).
• After dynamometer testing is
completed, turn the ESC system back
on by pressing the ESC switch again.
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
The Evaporative Emission Control System
is designed to prevent fuel vapors from
escaping 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.
