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 Your Vehicle
All Wheel Drive (AWD) Operation
If the AWD system determines there is a
need for four wheel drive, the engine's
driving power is distributed to all four
wheels automatically.
For safe AWD operation
Before driving

[Make sure all passengers are wearing
seat belts.

[Sit upright and closer to the steering
wheel than usual. Adjust the steering
wheel to a position comfortable for
you to drive.
Driving on snow-covered or icy roads

[Start off slowly by applying the
accelerator pedal gently.

[Use snow tires or tire chains.

[Keep sufficient distance between your
vehicle and the vehicle in front of you.

[Apply engine braking during
deceleration by using the paddle
shifter (manual shift mode) and
manually selecting a lower gear.

[Avoid speeding, rapid acceleration,
sudden brake applications, and sharp
turns to prevent skids.
Driving in sand or mud

[Maintain slow and constant speed.

[Use tire chains driving in mud if
necessary.

[Keep sufficient distance between your
vehicle and the vehicle in front of you.

[Reduce vehicle speed and always
check the road condition.

[Avoid speeding, rapid acceleration,
sudden brake applications, and sharp
turns to prevent getting stuck.
NOTICE
When the vehicle is stuck in snow, sand
or mud, place a nonslip material under
the drive wheels to provide traction
OR slowly spin the wheels in forward
and reverse directions which causes
a rocking motion that may free the
vehicle.
However, avoid running the engine
continuously at high RPM, doing so may
damage the AWD system.
Information

[When using Snow Tires, mount them
on all four wheels.

[When using tire chains, install them on
the rear tires. However, driving speed
must be below 18 mph (30 km/h) and
minimize the driving distance. High
speed or long-term driving with the
chains installed may malfunction or
damage the AWD system.

[If tire chains must be used, use
AutoSock (fabric snow chain) and
install the tire chain after reviewing
the instructions provided with the tire
chains.
For more information on Snow Tires and
Tire Chains, refer to "Winter Driving" in
this chapter.

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.

deceleration or steering, vehicle height
adjustment becomes temporarily
disabled. If the vehicle escapes from
such dangerous situation, vehicle height
adjustment is enabled again.

[When the vehicle is lifted up with a
lift or jack, height adjustment may be
disabled to protect the system. If the
vehicle engine is started or you start
driving, the function is enabled again.

[Leaving the vehicle parked for long
time may lower the vehicle height. The
vehicle height returns to its original
position when the engine is started.

[If the battery is either overcharged or
discharged, vehicle height adjustment
is disabled to protect the system and a
temporary warning message may be
displayed.

[If the vehicle height adjustment is
operated repeatedly, the function may
be temporarily disabled due to the
overheated compressor. It is to prevent
the breakdown of related parts.

CUSTOM Mode Features
SMART mode
SMART mode selects the proper driving
mode among SMART ECO, SMART
COMFORT and SMART SPORT by judging
the driver's driving habits (for example,
mild or dynamic) from the brake pedal
depression or the steering wheel
operation.
Various driving situations, which you may
encounter in SMART mode

[The driving mode automatically
changes to ECO mode after a certain
period of time, when you gently
depress the accelerator pedal (Your
driving is categorized to be mild.).

[The driving mode automatically
changes from SMART ECO mode
to SMART COMFORT mode after a
certain period of time, when you
sharply or repetitively depress the
accelerator pedal.

[The driving mode automatically
changes to SMART COMFORT mode
with the same driving patterns, when
the vehicle starts to drive on an
upward slope of a certain angle. The
driving mode automatically returns to
SMART ECO mode, when the vehicle
enters a leveled road.

[The driving mode automatically
changes to SMART SPORT mode
only in harsh driving situations. In
most of the normal driving situations,
the driving mode sets to be either
in SMART ECO mode or in SMART
COMFORT mode.
[The driving mode automatically
changes to SMART SPORT, when
you abruptly accelerate the vehicle
or repetitively operate the steering
wheel (Your driving is categorized
to be sporty.). In this mode, your
vehicle drives in a lower gear for
abrupt accelerating or decelerating
and increases the engine brake
performance.
For general description of SMART ECO,
SMART COMFORT, and SMART SPORT
modes, refer to “ECO, COMFORT, SPORT
mode features”.

SPECIAL DRIVING CONDITIONS
Hazardous Driving Conditions
When hazardous driving elements
are encountered such as water, snow,
ice, mud and sand, take the following
precautions:

[Drive cautiously and maintain a longer
braking distance.

[Avoid abrupt braking or steering.

[When your vehicle is stuck in
snow, mud, or sand, use second
gear. Accelerate slowly to avoid
unnecessary wheel spin.

[Put sand, rock salt, tire chains or other
non-slip materials under the wheels to
provide additional traction while the
vehicle becomes stuck in ice, snow,
or mud.
WARNING
Downshifting with an automatic
transmission while driving on slippery
surfaces can cause an accident. The
sudden change in tire speed could
cause the tires to skid. Be careful when
downshifting on slippery surfaces.
Rocking the Vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between R (Reverse)
and a forward gear.
Try to avoid spinning the wheels, and do
not race the engine.
To prevent transmission wear, wait until
the wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on the
accelerator pedal while the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes a
rocking motion that may free the vehicle.
WARNING
If the vehicle is stuck and excessive
wheel spin occurs, the temperature
in the tires can increase very quickly.
If the tires become damaged, a tire
blow out or tire explosion can occur.
This condition is dangerous - you and
others may be injured. Do not attempt
this procedure if people or objects are
anywhere near the vehicle.
If you attempt to free the vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire or
other damage. Try to avoid spinning the
wheels as much as possible to prevent
overheating of either the tires or the
engine. DO NOT allow the vehicle to
spin the wheels above 35 mph
(56 km/h).

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.
