Certification label
OBH059070
The certification label is located on the
driver’s door sill at the center pillar and
shows the maximum allowable weight of
the fully loaded vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight of the vehicle,
all occupants, fuel and cargo.
This label also tells you the maximum
weight that can be supported by the
front and rear axles, called Gross Axle
Weight Rating (GAWR).
The total weight of the vehicle, including
all occupants, accessories, cargo, and
trailer tongue load must not exceed the
Gross Vehicle Weight Rating (GVWR) or
the Gross Axle Weight Rating (GAWR).
To find out the actual loads on your front
and rear axles, you need to go to a weigh
station and weigh your vehicle. Be sure
to spread out your load equally on both
sides of the centerline.
WARNING
Overloading
• Never exceed the GVWR for your
vehicle, the GAWR for either the front
or rear axle and vehicle capacity
weight. Exceeding these ratings
can affect your vehicle’s handling
and braking ability, and cause an
accident.
• Do not overload your vehicle.
Overloading your vehicle can cause
heat buildup in your vehicle’s tires
and possible tire failure, increased
stopping distances and poor vehicle
handling-all of which may result in a
crash.
NOTICE
Overloading your vehicle may cause
damage. Repairs would not be covered
by your warranty. Do not overload your
vehicle.
WARNING
If you carry items inside your vehicle
(e.g., suitcases, tools, packages, or
anything else), they are moving as fast
as the vehicle. If you have to stop or
turn quickly, or if there is a crash, the
items will keep going and can cause
an injury if they strike the driver or a
passenger.
• Put items in the cargo area of your
vehicle. Try to spread the weight
evenly.
• Do not stack items, like suitcases,
inside the vehicle above the tops of
the seats.
• Do not leave an unsecured child
restraint in your vehicle.
• When you carry something inside the
vehicle, secure it.

Low Tire Pressure Telltale
Low Tire Pressure LCD Display
with Position Indicator
ODN8049019L
When the tire pressure monitoring
system warning indicators are
illuminated and the warning message
is displayed on the cluster LCD
display, one or more of your tires is
significantly under-inflated. The LCD
position indicator will indicate which
tire is significantly under-inflated by
illuminating the corresponding position
light.
If any of your tire pressures are indicated
as being low, immediately reduce
your speed, avoid hard cornering, and
anticipate increased stopping distances.
You should stop and check your tires
as soon as possible. Inflate the tires to
the proper pressure as indicated on the
vehicle’s placard or tire inflation pressure
label located on the driver’s side center
pillar outer panel.
If you cannot reach a service station or
if the tire cannot hold the newly added
air, replace the low pressure tire with the
spare tire. (if equipped)
The Low Tire Pressure LCD position
indicator will remain on and the TPMS
Malfunction Indicator may blink for one
minute and then remain illuminated until
you have the low pressure tire repaired
and replaced on the vehicle.
NOTICE
The spare tire is not equipped with a
tire pressure sensor.
CAUTION
In winter or cold weather, the Low Tire
Pressure Telltale may be illuminated if
the tire pressure was adjusted to the
recommended tire inflation pressure
in warm weather. It does not mean
your TPMS is malfunctioning because
the decreased temperature leads to a
proportional lowering of tire pressure.
When you drive your vehicle from a
warm area to a cold area or from a cold
area to a warm area, or the outside
temperature is greatly higher or lower,
you should check the tire inflation
pressure and adjust the tires to the
recommended tire inflation pressure.
WARNING
Low pressure damage
Significantly low tire pressure makes
the vehicle unstable and can contribute
to loss of vehicle control and increased
braking distances.
Continued driving on low pressure tires
can cause the tires to overheat and fail.

Maintenance

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.

WARNING
Recommended pressures must be
maintained for the best ride, vehicle
handling, and minimum tire wear.
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and lead to
sudden tire failure that could result
in loss of vehicle control resulting in
an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result in
the loss of vehicle control resulting
in an accident. This risk is much
higher on hot days and when
driving for long periods at high
speeds.
CAUTION
• Under-inflation results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation is also
possible. Keep your tire pressures
at the proper levels. If a tire
frequently needs refilling, have
it checked by an authorized
HYUNDAI dealer.
• Over-inflation produces a harsh
ride, excessive wear at the center
of the tire tread, and a greater
possibility of damage from road
hazards.
Check Tire Inflation Pressure
Check your tires, including the spare
tire, once a month or more.
How to check
Use a good quality tire pressure
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 when they are under-
inflated.
Remove the valve cap from the tire
valve stem. Press the tire gauge
firmly onto the valve to get a
pressure measurement. If the cold
tire inflation pressure matches the
recommended pressure on the tire
label located on the driver’s side
center pillar or in this manual. No
further adjustment is necessary. If
the pressure is low, add air until you
reach the recommended pressure.
Make sure to put the valve caps
back on the valve stems. 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.
If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gauge. Be
sure to put the valve caps back on
the valve stems. 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.

All Season Tires
HYUNDAI specifies all season
tires on some models to provide
good performance for use all year
round, including snowy and icy
road conditions. All season tires
are identified by ALL SEASON and/
or M+S (Mud and Snow) on the tire
sidewall. Snow tires have better
snow traction than all season tires
and may be more appropriate in
some areas.
Summer Tires
HYUNDAI specifies summer tires on
some models to provide superior
performance on dry roads. Summer
tire performance is substantially
reduced in snow and ice. Summer
tires do not have the tire traction
rating M+S (Mud and Snow) on
the tire side wall. If you plan to
operate your vehicle in snowy or icy
conditions, HYUNDAI recommends
the use of snow tires or all season
tires on all four wheels.
Snow Tires
If you equip your car with snow
tires, they should be the same size
and have the same load capacity as
the original tires. Snow tires should
be installed on all four wheels;
otherwise, poor handling may result.
Snow tires should carry 4 psi (28 kPa)
more air pressure than the pressure
recommended for the standard
tires on the tire label on the driver’s
side of the center pillar, or up to the
maximum pressure shown on the tire
sidewall, whichever is less. Do not
drive faster than 75 mph (120 km/h)
when your vehicle is equipped with
snow tires.
Radial-Ply Tires
Radial-ply tires provide improved
tread life, road hazard resistance
and smoother high speed ride. The
radial-ply tires used on this vehicle
are of belted construction, and are
selected to complement the ride
and handling characteristics of your
vehicle.
Radial-ply tires have the same load
carrying capacity, as bias-ply or
bias belted tires of the same size,
and use the same recommended
inflation pressure. Mixing of radial-
ply tires with bias-ply or bias belted
tires is not recommended. Any
combinations of radial-ply and bias-
ply or bias belted tires when used
on the same vehicle will seriously
deteriorate vehicle handling. The
best rule to follow is: Identical pairs
of radial-ply tires should always be
used as a set for the front tires and a
set for the rear tires.
Longer wearing tires can be more
susceptible to irregular tread wear.
It is very important to follow the tire
rotation interval in this chapter to
achieve the tread life potential of
these tires. Cuts and punctures in
radial-ply tires are repairable only in
the tread area, because of sidewall
flexing. Consult your tire dealer for
radial-ply tire repairs.
WARNING
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.
