Certification label
The certification label is located on
the driver's door sill at the center pil-
lar and shows the maximum allow-
able weight of the fully loaded vehi-
cle. 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 maxi-
mum weight that can be supported
by the front and rear axles, called
Gross Axle Weight Rating.
The total weight of the vehicle,
including all occupants, accessories,
cargo, and trailer tongue load must
not exceed the Gross Vehicle Weight
Rating or the Gross Axle Weight
Rating. 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.Overloading your vehicle may
cause damage. Repairs would not
be covered by your warranty. Do
not overload your vehicle.
NOTICE
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 stop-
ping distances and poor vehi-
cle handling-all of which may
result in a crash.

What to do in an emergency
Tire Pressure Monitoring
System
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system that illu-
minates a low tire pressure telltale
when one or more of your tires is sig-
nificantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and
check your tires as soon as possible,
and inflate them to the proper pres-
sure. Driving on a significantly under-
inflated tire causes the tire to over-
heat and can lead to tire failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life, and may
affect the vehicle's handling and
stopping ability.Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver's responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not oper-
ating properly. The TPMS malfunc-
tion indicator is combined with the
low tire pressure telltale. When the
system detects a malfunction, the
telltale will flash for approximately
one minute and then remain continu-
ously illuminated. This sequence will
continue upon subsequent vehicle
start-ups as long as the malfunction
exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunc-
tions may occur for a variety of rea-
sons, including the installation of
replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
nate tires and wheels allow the
TPMS to continue to function proper-
ly. Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
may cause loss of vehicle con-
trol resulting in an accident.

Low Tire
Pressure LCD
Display with
Position
Indicator
When the tire pressure monitoring
system warning indicators are illumi-
nated and the warning message is
displayed on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The LCD posi-
tion indicator will indicate which tire
is significantly under-inflated by illu-
minating the corresponding position
light.
If any of your tire pressures are indi-
cated as being low, immediately
reduce your speed, avoid hard cor-
nering, and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle’s placard or tire inflation pressure
label located on the driver's side cen-
ter 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.
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.

What to do in an emergency
Information
The spare tire is not equipped with a
tire pressure sensor.
In winter or cold weather, the Low
Tire Pressure Telltale may be illu-
minated if the tire pressure was
adjusted to the recommended tire
inflation pressure in warm weath-
er. It does not mean your TPMS is
malfunctioning because the
decreased temperature leads to a
proportional lowering of tire pres-
sure.
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 recommend-
ed tire inflation pressure.
TPMS Malfunction
Indicator
The TPMS Malfunction Indicator will
illuminate after it blinks for approxi-
mately one minute when there is a
problem with the Tire Pressure
Monitoring System.
Have the system checked by an
authorized retailer of Genesis
Branded products as soon as possi-
ble.
Information
If there is a malfunction with the
TPMS, the individual tire pressures in
the cluster LCD display will not be
available. Have the system checked by
an authorized retailer of Genesis
Branded products as soon as possible.
The TPMS Malfunction Indicator
may illuminate after blinking for
one minute if the vehicle is near
electric power supply cables or
radio transmitters such as police
stations, government and public
offices, broadcasting stations,
military installations, airports,
transmitting towers, etc.
Additionally, the TPMS
Malfunction Indicator may illumi-
nate if snow chains are used or
electronic devices such as com-
puters, chargers, remote starters,
navigation, etc. This may interfere
with normal operation of the
TPMS.

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.

What to do in an emergency
If it is hard to loosen the tire hold-
down wing bolt by hand, you can
loosen it easily using the jack handle.
1. Put the jack handle (1) inside of
the tire hold-down wing bolt.
2. Turn the tire hold-down wing bolt
counterclockwise with the jack
handle.
Changing tires
A vehicle can slip or roll off of a
jack causing serious injury or
death to you or those nearby.
Take the following safety pre-
cautions:
• Never place any portion of
your body under a vehicle that
is supported by a jack.
• NEVER attempt to change a
tire in the lane of traffic.
ALWAYS move the vehicle
completely off the road on
level, firm ground away from
traffic before trying to change
a tire. If you cannot find a
level, firm place off the road,
call a towing service for assis-
tance.
• Be sure to use the jack provid-
ed with the vehicle.
• ALWAYS place the jack on the
designated jacking positions
on the vehicle and NEVER on
the bumpers or any other part
of the vehicle for jacking sup-
port.
• Do not start or run the engine
while the vehicle is on the
jack.
• Do not allow anyone to remain
in the vehicle while it is on the
jack.
• Keep children away from the
road and the vehicle.

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.

Your vehicle has metric threads
on the studs and lug nuts. Make
certain during tire changing that
the same nuts that were removed
are reinstalled. If you have to
replace your lug nuts make sure
they have metric threads to avoid
damaging the studs and ensure
the wheel is properly secured to
the hub. Consult an authorized
retailer of Genesis Branded prod-
ucts for assistance.
If any of the equipment such as the
jack, lug nuts, studs, or other equip-
ment is damaged or in poor condi-
tion, do not attempt to change the
tire and call for assistance.
Use of compact spare tires
Compact spare tires are designed for
emergency use only. Drive carefully
on the compact spare tire and
always follow the safety precautions.
NOTICE
To prevent compact spare tire
failure and loss of control pos-
sibly resulting in an accident:
• Use the compact spare tire
only in an emergency.
• NEVER operate your vehicle
over 50 mph (80 km/h).
• Do not exceed the vehicle's
maximum load rating or the
load carrying capacity shown
on the sidewall of the com-
pact spare tire.
• Do not use the compact spare
tire continuously. Repair or
replace the original tire as
soon as possible to avoid fail-
ure of the compact spare tire.
