NOTICE

[It is permissible to add 3 psi to the standard tire pressure specification if colder
temperatures are expected soon.

[Tires typically lose 1 psi (7 kPa) for every 12°F temperature drop. If extreme
temperature variations are expected, recheck your tire pressure as necessary to
keep them properly inflated.

[Tire inflation pressures will vary with changes in elevation. If driving in areas of
higher or lower elevation, be sure to check and adjust for proper tire inflation.
CAUTION

[When replacing tires, use the same size originally supplied with the vehicle.

[Using tires of a different size can damage the related parts or not work properly.

[When replacing tires, ALWAYS use the same size, type, construction and tread
pattern supplied with the vehicle for all tires.

ESC OFF usage
When Driving
The ESC OFF mode should only be used
briefly to help free the vehicle if stuck in
snow or mud, by temporarily stopping
operation of ESC, to maintain wheel
torque.
To turn ESC off while driving, press the
ESC OFF button while driving on a flat
road surface.
NOTICE
To prevent damage to the transmission:

[Do not allow wheel(s) of one axle to
spin excessively while the ESC, ABS,
and Parking Brake warning lights
are displayed. The repairs would not
be covered by the vehicle warranty.
Reduce engine power and do not
spin the wheel(s) excessively while
these lights are displayed.

[When operating the vehicle
on a dynamometer, make sure
ESC is turned off (ESC OFF light
illuminated).
Information
Turning ESC off does not affect ABS or
standard brake system operation.
Vehicle Stability Management
(VSM)
Vehicle Stability Management is a
function of the Electronic Stability
Control (ESC) system. It helps the vehicle
stay stable when accelerating or braking
suddenly on wet, slippery and rough
roads where traction over the four tires
can suddenly become uneven.
WARNING
Take the following precautions when
using Vehicle Stability Management:

[ALWAYS check the speed and the
distance to the vehicle ahead. VSM
is not a substitute for safe driving
practices.

[Never drive too fast for the road
conditions. VSM will not prevent
accidents. Excessive speed in bad
weather, on slippery and uneven
roads can result in severe accidents.

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.

Emergency Situations
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
compact 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 compact 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.
• Do not tow a trailer while the compact
spare tire is installed.
Information
When the original tire and wheel are
repaired and reinstalled on the vehicle, the
wheel bolt torque must be set correctly.
The correct wheel bolt tightening torque is
101~116 lbf·ft (14~16 kgf·m).
NOTICE
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 approximately
1 in. (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.
• Do not suddenly accelerate or
decelerate 0 ~ 25 mph (0 ~ 40 km/h)
in any driving mode. It may cause
leakage of transfer oil.

ENGINE OIL
Suspension Mounting Bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque.
Steering Gear box, Linkage &
Boots/Lower Arm Ball Joint
With the vehicle stopped and the engine
off, check for excessive free-play in the
steering wheel. Check the linkage for
bends or damage. Check the dust boots
and ball joints for deterioration, cracks,
or damage.
Replace any damaged parts.
Drive Shafts and Boots
Check the drive shafts, boots and clamps
for cracks, deterioration, or damage.
Replace any damaged parts and, if
necessary, repack the grease.
Air Conditioning Refrigerant
Check the air conditioning lines and
connections for leakage and damage.
Checking the Engine Oil Level
Engine oil is used for lubricating,
cooling, and operating various hydraulic
components in the engine. Engine oil
consumption while driving is normal,
and it is necessary to check and refill the
engine oil regularly. Also, check and refill
the oil level within the recommended
maintenance schedule to prevent
deterioration of oil performance.
Check the engine oil following the below
procedure.
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on the level
ground in P (Park) with the parking
brake set and the wheels blocked.
3. Turn the engine on and warm
the engine up until the coolant
temperature reaches a constant
normal temperature.
4. Turn the engine off, remove the oil
filler cap and pull the dipstick out.
Wait for 15 minutes for the oil to return
to the oil pan.
5. Wipe the dipstick clean and re-insert
it fully.

Tire Rotation
To equalize tread wear, Genesis
Branded Vehicle recommends that
the tires be rotated according to the
maintenance schedule or sooner if
irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear
is usually caused by incorrect tire
pressure, improper wheel alignment,
out-of-balance wheels, severe braking
or severe cornering. Look for bumps or
bulges in the tread or side of the tire.
Replace the tire if you find any of these
conditions. Replace the tire if fabric or
cord is visible. After rotation, be sure to
bring the front and rear tire pressures
to specification and check wheel bolt
tightness (proper torque is 101~116
lbf·ft [14-16 kgf·m].
ORS091056L
Disc brake pads should be inspected
for wear whenever tires are rotated.
Information
The outside and inside of the
unsymmetrical tire is distinguishable.
When installing an unsymmetrical
tire, be sure to install the side marked
“outside” face the outside. If the side
marked “inside” is installed on the
outside, it will have a negative effect
on vehicle performance.
WARNING

[Do not use the compact spare
tire for tire rotation.

[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.
