Changing a Tire with TPMS
If you have a flat tire, the Low Tire
Pressure and LCD position indicator
will come on. Have the flat tire
repaired by an authorized retailer of
Genesis Branded products as soon
as possible or replace the flat tire
with the spare tire.
Never use a puncture-repairing
agent not approved by authorized
retailer of Genesis Branded prod-
ucts to repair and/or inflate a low
pressure tire. Tire sealant not
approved by authorized retailer of
Genesis Branded products may
damage the tire pressure sensor.
The spare tire does not come with a
tire pressure monitoring sensor.
When the low pressure tire or the flat
tire is replaced with the spare tire,
the Low Tire Pressure LCD position
indicator will remain on. Also, the
TPMS Malfunction Indicator will illu-
minate after blinking for one minute if
the vehicle is driven at speed above
15.5 mph (25 km/h) for approximate-
ly 20 minutes.
Once the original tire equipped with
a tire pressure monitoring sensor is
reinflated to the recommended pres-
sure and reinstalled on the vehicle,
the Low Tire Pressure LCD position
indicator and TPMS Malfunction
Indicator will go off within a few min-
utes of driving.
If the indicators do not disappear
after a few minutes, please visit an
authorized retailer of Genesis
Branded products.Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem (except for
the spare tire). You must use TPMS
specific wheels. It is recommended
that you always have your tires serv-
iced by an authorized retailer of
Genesis Branded products.
You may not be able identify a tire
with low pressure by simply looking
at it. Always use a good quality tire
pressure gage to measure the tire's
inflation pressure. Please note that a
tire that is hot (from being driven) will
have a higher pressure measure-
ment than a tire that is cold.
A cold tire means the vehicle has
been sitting for 3 hours and driven for
less than 1 mile (1.6 km) in that 3
hour period.
Allow the tire to cool before measur-
ing the inflation pressure. Always be
sure the tire is cold before inflating to
the recommended pressure.
NOTICE
• The TPMS cannot alert you to
severe and sudden tire dam-
age caused by external fac-
tors such as nails or road
debris.
• If you feel any vehicle instabil-
ity, immediately take your foot
off the accelerator, apply the
brakes gradually with light
force, and slowly move to a
safe position off the road.

The jack, jack handle, and wheel lug
nut wrench are stored in the luggage
compartment under the luggage box
cover.
The jack is provided for emergency
tire changing only.Turn the winged hold down bolt
counterclockwise to remove the
spare tire.
Store the spare tire in the same com-
partment by turning the winged hold
down bolt clockwise.
To prevent the spare tire and tools
from "rattling", store them in their
proper location.
IF YOU HAVE A FLAT TIRE
Changing a tire can be danger-
ous. Follow the instructions in
this section when changing a
tire to reduce the risk of serious
injury or death.
WARNING
Be careful as you use the jack

What to do in an emergency
9. Insert the jack handle into the jack
and turn it clockwise, raising the
vehicle until the tire clears the
ground. Make sure the vehicle is
stable on the jack.
10. Loosen the lug nuts with the
wheel lug nut wrench and
remove them with your fingers.
Remove the wheel from the
studs and lay it flat on the ground
out of the way. Remove any dirt
or debris from the studs, mount-
ing surfaces, and wheel.
11. Install the spare tire onto the
studs of the hub.
12. Tighten the lug nuts with your fin-
gers onto the studs with the
smaller end of the lug nuts clos-
est to the wheel.
13. Lower the vehicle to the ground
by turning the jack handle coun-
terclockwise.14. Use the wheel lug nut wrench to
tighten the lug nuts in the order
shown. Double-check each lug
nut until they are tight. After
changing tires, have an author-
ized retailer of Genesis Branded
products tighten the lug nuts to
their proper torque as soon as
possible.The wheel lug nut
should be tightened to 79~94
lbf·ft (11~13 kgf·m).
If you have a tire gauge, check the
tire pressure (see "Tires and Wheels"
in chapter 8 for tire pressure instruc-
tions.). If the pressure is lower or
higher than recommended, drive
slowly to the nearest service station
and adjust it to the recommended
pressure. Always reinstall the valve
cap after checking or adjusting tire
pressure. If the cap is not replaced,
air may leak from the tire. If you lose
a valve cap, buy another and install it
as soon as possible. After changing
tires, secure the flat tire and return
the jack and tools to their proper stor-
age locations.

What to do in an emergency
When driving with the compact spare
tire mounted to your vehicle:
• Check the tire pressure after
installing the compact spare tire.
The compact spare tire should be
inflated to 60 psi (420 kPa).
• Do not take this vehicle through an
automatic car wash while the com-
pact spare tire is installed.
• Do not use the compact spare tire
on any other vehicle because this
tire has been designed especially
for your vehicle.
• The compact spare tire's tread life
is shorter than a regular tire.
Inspect your compact spare tire
regularly and replace worn com-
pact spare tires with the same size
and design, mounted on the same
wheel.
• Do not use more than one compact
spare tire at a time.
Information
When the original tire and wheel are
repaired and reinstalled on the vehi-
cle, the lug nut torque must be set cor-
rectly. The correct lug nut tightening
torque is 79~94 lbf·ft (11~13 kgf·m).
To prevent damaging the compact
spare tire and your vehicle:
• Drive slowly enough for the road
conditions to avoid all hazards,
such as a potholes or debris.
• Avoid driving over obstacles.
The compact spare tire diameter
is smaller than the diameter of a
conventional tire and reduces
the ground clearance approxi-
mately 1 inch (25 mm).
• Do not use tire chains on the
compact spare tire. Because of
the smaller size, a tire chain will
not fit properly.
• Do not use the compact spare
tire on any other wheels, nor
should standard tires, snow
tires, wheel covers or trim rings
be used with the compact spare
wheel.

Owner Maintenance Schedule
When you stop for fuel:
• Check the engine oil level.
• Check the coolant level in the
engine coolant reservoir.
• Check the windshield washer fluid
level.
• Check the tire for low or under-
inflated tires.
While operating your vehicle:
• Note any changes in the sound of
the exhaust or any smell of exhaust
fumes in the vehicle.
• Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
• Notice if your vehicle constantly
turns slightly or "pulls" to one side
when traveling on smooth, level
road.
• When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
• If any slipping or changes in the
operation of your transmission
occurs, check the transmission
fluid level.
• Check the automatic transmission
P (Park) function.
• Check the parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
• Check coolant level in the engine
coolant reservoir.
• Check the operation of all exterior
lights, including the brake lights,
turn signals and hazard warning
flashers.
• Check the inflation pressures of all
tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
• Check for loose wheel lug nuts. Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.

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.
All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.
TIRES AND WHEELS
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 pres-
sure. Tires with too much or
too little pressure wear
unevenly causing poor han-
dling.
• 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 effec-
tiveness, steering) control, or
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 recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle's Anti-Lock Brake System
(ABS) resulting in a serious
accident.

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).
Warm tires normally exceed recom-
mended cold tire pressures 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-inflat-
ed. For recommended inflation pres-
sure, refer to "Tire and Wheels" in
chapter 8.• Under-inflation results in exces-
sive 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 retailer of Genesis
Branded products.
• Over-inflation produces a harsh
ride, excessive wear at the cen-
ter of the tire tread, and a greater
possibility of damage from road
hazards.
NOTICE
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 peri-
ods at high speeds.
