Driving Your Vehicle
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
(for example, 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.

12. Install the spare tire over the centering
pin P and then push in the spare tire.
13. Tighten the wheel bolts with your
fingers onto the studs with the smaller
end of the wheel bolts closest to the
wheel.
14. Pull out the centering pin P and
tighten the last wheel bolt.
15. Lower the vehicle to the ground
by turning the jack handle
counterclockwise.
ORS081042LORS081042L
16. Use the wheel lug wrench to tighten
the wheel bolts in the order shown.
Double-check each wheel bolts until
they are tight. After changing tires,
have an authorized retailer of Genesis
Branded products tighten the wheel
bolts to their proper torque as soon
as possible. The wheel bolt should
be tightened to 101~116 lbf·ft (14~16
kgf·m).
If you have a tire gauge, check the
tire pressure (see “Tires and Wheels”
section in chapter 2 for tire pressure
instructions.). 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
storage locations.

NOTICE
Check the tire pressure as soon as
possible after installing a spare tire.
Adjust it to the recommended pressure.
CAUTION
Your vehicle has metric threads on the
studs and wheel bolts. Make certain
during tire changing that the same bolts
that were removed are reinstalled. If
you have to replace your wheel bolts
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 products for
assistance.
If any of the equipment such as the jack,
wheel bolts, studs, or other equipment
is damaged or in poor condition, 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.
WARNING
To prevent compact spare tire failure
and loss of control possibly 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 compact spare tire.
• Do not use the compact spare tire
continuously. Repair or replace the
original tire as soon as possible to
avoid failure of the compact spare
tire.

4. Unscrew the valve cap from the valve
of the defective wheel and screw the
filling hose O of the sealant bottle
onto the valve.
CAUTION
Securely install the sealant filling hose
to the valve. If not, sealant may flow
backward, possibly clogging the filling
hose.
ORS081009ORS081009
5. Plug the compressor power cord P
into the vehicle power outlet.
NOTICE
Only use the front passenger side
power outlet when connecting the
power cord.6. With the Engine Start/Stop button
in the ON position, switch on
the compressor and let it run for
approximately 5~7 minutes to fill the
sealant up to proper pressure. (refer
to the Tire and Wheels, chapter 2).
The inflation pressure of the tire after
filling is unimportant and will be
checked/ corrected later. Be careful
not to overinflate the tire and stay
away from the tire when filling it.
CAUTION
Tire pressure
Do not attempt to drive your vehicle if
the tire pressure is below 200 kPa (29
psi). This could result in an accident due
to sudden tire failure.
WARNING
Carbon monoxide
Do not leave your vehicle running in
a poorly ventilated area for extended
periods of time. Carbon monoxide
poisoning and suffocation can occur.
7. Switch off the compressor.
8. Detach the hoses from the sealant
bottle connector and from the tire
valve.

A : Front,
B : Rear
If towing is necessary, we recommend
you have it done by an authorized
retailer of Genesis Branded products or a
commercial tow truck service.
If towing service is not available in
an emergency, your vehicle may be
temporarily towed using a cable or chain
secured to the emergency towing hook
at the front (or rear) of the vehicle.
Use extreme caution when towing the
vehicle with a cable or chain. A driver
must be in the vehicle to steer it and
operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a short
distance and at low speeds. Also, the
wheels, axles, power train, steering
and brakes must all be in good working
condition.
CAUTION
The driver must be in the vehicle for
steering and braking operations when
the vehicle is being towed. Passengers
other than the driver must not be in the
vehicle.
Always follow these emergency towing
precautions:
• Press the Engine Start/Stop button
to the ACC position so the steering
wheel is not locked.
• Shift the gear to N (Neutral).
• Release the parking brake.
• Depress the brake pedal with more
force than normal as you will have
reduced braking performance.
• More steering effort will be required
because the power steering system
will be disabled.
• Use a vehicle heavier than your own to
tow your vehicle.
• The drivers of both vehicles should
communicate with each other
frequently.
• Before emergency towing, check that
the hook is not broken or damaged.
• Fasten the towing cable or chain
securely to the hook.
• Do not jerk the hook. Apply steady
and even force.

Information
The coolant level is influenced by the
engine temperature. Before checking or
refilling the coolant, turn the engine off.
WARNING
The electric motor for the
cooling fan may continue to
operate or start up when the
engine is not running and can
cause serious injury. Keep
hands, clothing and tools away
from the rotating fan blades of
the cooling fan.
Always turn off the vehicle unless the
vehicle has to be inspected with the
engine on. Be cautious as the cooling
fan may operate if the negative (-)
battery terminal is not disconnected.
WARNING
Make sure the coolant cap is properly
closed after refilling coolant. Otherwise
the engine could be overheated while
driving.
