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.

Safety System
You will find many safety precautions
and recommendations throughout this
section, and throughout this manual.
The safety precautions in this section are
among the most important.
Always Wear Your Seat Belt
A seat belt is your best protection in all
types of accidents. Air bags are designed
to supplement seat belts, not replace
them. So even though your vehicle is
equipped with air bags, ALWAYS make
sure you and your passengers wear your
seat belts, and wear them properly.
Restrain All Children
All children under age 13 should ride
in your vehicle properly restrained in a
rear seat, not the front seat. Infants and
small children should be restrained in
an appropriate Child Restraint System.
Larger children should use a booster
seat with the lap/shoulder belt until they
can use the seat belt properly without a
booster seat.
Air Bag Hazards
While air bags can save lives, they can
also cause serious or fatal injuries to
occupants who sit too close to them, or
who are not properly restrained. Infants,
young children, and short adults are at
the greatest risk of being injured by an
inflating air bag. Follow all instructions
and warnings in this manual.
Driver Distraction
Driver distraction presents a serious and
potentially deadly danger, especially for
inexperienced drivers. Safety should be
the first concern when behind the wheel
and drivers need to be aware of the wide
array of potential distractions, such as
drowsiness, reaching for objects, eating,
personal grooming, other passengers,
and using mobile phones.Drivers can become distracted when
they take their eyes and attention off
the road or their hands off the wheel to
focus on activities other than driving.
To reduce your risk of distraction and an
accident:

[ALWAYS set up your mobile devices
(for example, MP3 players, phones,
navigation units, etc.) when your
vehicle is parked or safely stopped.

[ONLY use your mobile device when
allowed by laws and conditions permit
safe use. NEVER text or email while
driving. Most countries have laws
prohibiting drivers from texting. Some
countries and cities also prohibit
drivers from using handheld phones.

[NEVER let the use of a mobile device
distract you from driving. You have a
responsibility to your passengers and
others on the road to always drive
safely, with your hands on the wheel
as well as your eyes and attention on
the road.
Control Your Speed
Excessive speed is a major factor in crash
injuries and deaths. Generally, the higher
the speed, the greater the risk, but
serious injuries can also occur at lower
speeds. Never drive faster than is safe
for current conditions, regardless of the
maximum speed posted.
Keep Your Vehicle In Safe
Condition
Having a tire blowout or a mechanical
failure can be extremely hazardous. To
reduce the possibility of such problems,
check your tire pressures and condition
frequently, and perform all regularly
scheduled maintenance.
IMPORTANT SAFETY PRECAUTIONS

6-39
06
All Wheel Drive (AWD) delivers engine
power to front and rear wheels for
maximum traction. AWD is useful when
extra traction is required, such as when
driving on, muddy, wet, or snow-covered
roads.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH:

[Do not drive in conditions that
exceed the vehicles intended
design such as challenging off-road
conditions.

[Avoid high speeds when cornering or
turning.

[Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.

[The risk of a rollover is greatly
increased if you lose control of your
vehicle at highway speeds.

[Loss of control often occurs if two or
more wheels drop off the roadway
and the driver over steers to reenter
the roadway.

[In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
WARNING
If the AWD () warning light stays on
the instrument cluster, your vehicle
may have a malfunction with the
AWD system. Whenever the AWD
(
) warning light illuminates, have
the vehicle inspected by an authorized
retailer of Genesis Branded products as
soon as possible.
NOTICE

[Do not drive in water if the water
level is higher than the bottom of the
vehicle.

[Check your brake condition once
you are out of mud or water. Depress
the brake pedal several times as you
move slowly until you feel normal
braking condition is returned.

[Shorten your scheduled
maintenance interval if you drive in
off-road conditions such as sand,
mud or water (see "Maintenance
Under Severe Usage Conditions"
section in chapter 9).

[Always wash your vehicle thoroughly
after off road use, especially the
bottom of the vehicle.

[Be sure to equip the vehicle with four
tires of the same size and type.

[Make sure that a full time AWD
vehicle is towed by a flat bed tow
truck.

Driving up or down hills

[Driving uphill
-Before starting off, check if it is
possible to drive uphill.
-Drive as straight as possible.

[Driving downhill
-Do not change gear while driving
downhill. Select gear before driving
downhill.
-Drive slowly using engine braking
while driving downhill.
-Drive straight as possible.
WARNING
Exercise extreme caution driving up or
down steep hills. The vehicle may flip
over depending on the grade, terrain,
water and mud conditions.
WARNING
Do not drive across the contour of steep
hills. A slight change in the wheel angle
can destabilize the vehicle, or a stable
vehicle may lose stability if the vehicle
stops its forward motion. Your vehicle
may roll over and lead to a serious injury
or death.
Emergency Precautions
Tires
When replacing tires, be sure to equip
all four tires with the same size, type,
tread pattern, brand and load-carrying
capacity.
WARNING
Do not use tire and wheel with different
size and type from the one originally
installed on your vehicle. It can affect
the safety and performance of your
vehicle, which could lead to steering
failure or rollover causing serious injury.
In an emergency situation, a compact
spare tire may be used. But, do not use
the compact spare tire continuously.
Repair or replace the original tire as
soon as possible to avoid failure of the
differential or AWD system.

Driving Your Vehicle
Snow tires
WARNING
Snow tires should be equivalent in size and type to the vehicle’s standard tires.
Otherwise, the safety and handling of your vehicle may be adversely affected.
We recommend that you use snow tires when road temperature is below 45°F (7°C).
Refer to the below chart, and mount the recommended snow tire for your vehicle.
Standard tire Recommended snow tire
Tire size Wheel size Tire size Wheel size
245/45R20 8.5J x 20 245/45R20 8.5J x 20
275/40R20 9.5J x 20 275/40R20 9.5J x 20
245/40R21 8.5J x 21 245/40R21 8.5J x 21
275/35R21 9.5J x 21 275/35R21 9.5J x 21
If you mount snow tires on your vehicle, make sure to use the same Inflation pressure
as the original tires. Mount snow tires on all four wheels to balance your vehicle’s
handling in all weather conditions. The traction provided by snow tires on dry roads
may not be as high as your vehicle’s original equipment tires. Check with the tire dealer
for maximum speed recommendations.

Tire chains
ORS061025L
Since the sidewalls on some radial tires
are thinner than other types of tires,
they may be damaged by mounting
certain types of tire chains on them.
Do not mount tire chains on vehicles
equipped with aluminum wheels; if
possible use AutoSock® (fabric snow
chain or similar). Install AutoSock® after
reviewing the instructions provided
with AutoSock®. Damage to your vehicle
caused by improper use of fabric snow
chains are not covered by your vehicle
manufacturer's warranty.
Information
AutoSock® is a Registered trademark of
AutoSock.
WARNING
The use of AutoSock® (fabric snow
chain) may adversely affect vehicle
handling:

[Drive less than 20 mph (30 km/h)
or the AutoSock® manufacturer’s
recommended speed limit,
whichever is lower.

[Drive carefully and avoid bumps,
holes, sharp turns, and other road
hazards, which may cause the
vehicle to bounce.

[Avoid sharp turns or locked wheel
braking.
Disabling Rear Wheel Steering system to
install snow chains
ORS061036L
If the Rear Wheel Steering system is
applied, disable the system to protect the
vehicle when snow chains are installed.

Notes On the Safe Use of the Tire
Mobility Kit
• Park your vehicle at the side of the
road so that you can work with the
Tire Mobility Kit away from moving
traffic.
• To be sure your vehicle will not move,
even when you’re on fairly level
ground, always set your parking brake.
• Only use the Tire Mobility Kit for
sealing/inflation passenger vehicle
tires. Only punctured areas located
within the tread region of the tire can
be sealed using the tire mobility kit.
• Do not use on motorcycles, bicycles
or any other type of tires.
• When the tire and wheel are
damaged, do not use Tire Mobility Kit
for your safety.
• Use of the Tire Mobility Kit may not be
effective for tire damage larger than
approximately 0.16 in. (4 mm).
Please contact the nearest retailer of
Genesis Branded products if the tire
cannot be made roadworthy with the
Tire Mobility Kit.• Do not use the Tire Mobility Kit if a tire
is severely damaged by driving run flat
or with insufficient air pressure.
• Do not remove any foreign objects
such as nails or screws that have
penetrated the tire.
• Provided the vehicle is outdoors,
leave the engine running. Otherwise
operating the compressor may
eventually drain the vehicle battery.
• Never leave the Tire Mobility Kit
unattended while it is being used.
• Do not leave the compressor running
for more than 10 minutes at a time or
it may overheat.
• Do not use the Tire Mobility Kit if the
ambient temperature is below -22°F
(-30°C).
• In case of skin contact with the
sealant, wash the area thoroughly
with plenty of water. If the irritation
persists, seek medical attention.
• In case of eye contact with the
sealant, flush your eyes for at least 15
minutes. If the irritation persists, seek
medical attention.
• In case of swallowing the sealant,
rinse the mouth and drink plenty of
water. However, never give anything
to an unconscious person and seek
medical attention immediately.
• Long time exposure to the sealant
may cause damage to bodily tissue
such as kidney, etc.

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 size, type, 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.
ORS012024N
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 driven 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” section in chapter 2.
