ORS061019
The Multi-chamber air suspension uses
the air spring containing compressed
air to adjust and maintain the vertical
height of the vehicle both manually or
automatically, according to number of
passengers and load capacity. It also
controls the valve inside the air spring
to adjust stiffness of the air spring and
damper to maximize driving comforts.
Each driving mode provides different
ride comforts.
Vehicle Height Adjustment

[Press the vehicle height adjustment
button to adjust the height. Pressing
the button will raise the vehicle body
and the indicator light illuminates.
Pressing the button again will return
the vehicle height to its original
position and the indicator light turns
off.
[If the vehicle is driving in high speed,
the vehicle height adjustment is set
to automatic mode and the vehicle
height will return to its original
position although you press the
button.
-While above a certain speed, the
height will be automatically set
depending on the driving speed.
-Vehicle height may differ depending
on the drive mode.

[Depending on vehicle condition,
height adjustment will not operate or
stop operating, and the indicator light
blinks.
-When the Multi-chamber air
suspension is malfunctioning
-When the vehicle is lifted up.
-When the vehicle is not stable due
to a sudden brake or acceleration.
-When the air compressor is
overheated.
-When the vehicle is not parked on a
level ground.

[Vehicle height may automatically be
adjusted after 2/4/8/16 hours from
turning off the engine. It is due to the
changes in air temperature.
CAUTION
If the compressor air filter under the
vehicle body is submerged in water,
do not operate the air suspension.
Moisture inflow may damage the
system.

Multi-Chamber Air Suspension
Malfunction
OJWEV061048L
This message is displayed when there is
a malfunction with the Multi-chamber
air suspension system. Have the vehicle
inspected by an authorized retailer of
Genesis Branded products.
CAUTION

[When adjusting vehicle height, check
if there are any obstacles below or
above the vehicle.

[If air inside the suspension is
discharged, a warning message
will be displayed. If so, stop driving
and use a towing vehicle. Since
the vehicle height will be very low,
projections on the road may damage
the vehicle. See ‘Towing when the
air suspension malfunctions’ before
towing the vehicle.
Information

[Operating the air suspension may
cause a little noise when charging and
discharging the air.

[Adjusted vehicle height may vary
depending on the temperature and
surrounding environment.

[When the suspension warning message
is displayed, the system enables safe
mode to prevent secondary failure
and the vehicle performance may be
displayed differently.

[When the vehicle is parked on a slope,
or when the vehicle is in unstable
condition due to sudden acceleration,
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.

Additional Height Adjustment
Function
Multi-chamber air suspension recognizes
the driving condition to automatically
adjust vehicle height, spring stiffness,
and shock absorber damping force for
driving comfort and vehicle protection.
Additional vehicle height adjustment
operates automatically depending
on various conditions and it is not
necessarily displayed to the driver.
Off road driving
ORS061027
The vehicle adjusts vehicle height, spring
stiffness, and shock absorber damping
force when driving on a rough terrain
such as an unpaved road, to optimize
comfort and protect the vehicle.
Driving on a slope
ORS061028
The vehicle adjusts vehicle height, spring
stiffness, and shock absorber damping
force when driving over a steep slope,
to optimize comfort and protect the
vehicle.
Information

[Additional vehicle height adjustment
function operates differently
depending on various driving and
system conditions. In some cases, its
operability and actuation speed may
vary.

[When the vehicle speed is below 6 mph
(10 km/h) or above 37 mph (60 km/h),
the safety bump driving function may
be disabled.

[When the vehicle speed is above 18
mph (30 km/h), the off road driving
and slope driving function may be
disabled.

Driving Your Vehicle
Towing When the Air Suspension
Malfunction
ORS061020L
Driving while the suspension is
malfunctioning and the air inside the
suspension is discharged may damage
the vehicle.
Use the towing vehicle and we
recommend that you have the system
checked by an authorized retailer of
Genesis Branded products.
Use only flatbed tow trucks. Other
towing methods may damage the
vehicle.
ORS061021L
The flatbed tow truck must be a safety
loader type which has a loading angle M
less than 6º.
Towing with a loading angle larger than
6º may damage the vehicle.

Driving Your Vehicle
NOTICE
If you drive without disabling the
Rear Wheel Steering system in the
infotainment system after installing
snow chains, the snow chains can
damage your vehicle’s body or chassis
parts. When you hear the snow chain
hitting the vehicle, stop the vehicle and
check whether the snow chains are
installed properly and whether the Rear
Wheel Steering system is disabled.
Information

[Install AutoSock® (fabric snow chain)
only in pairs and on the rear tires.
It should be noted that installing
AutoSock (fabric snow chain) on the
tires will provide a greater driving
force, but will not prevent side skids.

[Do not install studded tires without
first checking local, state and municipal
regulations for possible restrictions
against their use.
Chain Installation
When installing AutoSock® (fabric
snow chain), follow the manufacturer's
instructions and mount them as tightly
as possible. Drive slowly (less than 20
mph (30 km/h)) with AutoSock® installed.
If you hear the fabric snow chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the AutoSock® as soon as you begin
driving on cleared roads.
When mounting AutoSock®, park the
vehicle on level ground away from traffic.
Turn on the vehicle Hazard Warning
Flasher and place a triangular emergency
warning device behind the vehicle (if
available).
Always place the vehicle in P (Park),
apply the parking brake and turn off the
engine before installing tire chains.
NOTICE
When using AutoSock® (fabric snow
chain):

[Wrong size fabric snow chains or
improperly installed fabric snow
chains can damage your vehicle's
brake lines, suspension, body and
wheels.

[If you hear noise caused by fabric
snow chains contacting the body,
retighten the fabric snow chains to
prevent contact with the vehicle
body.

[To prevent body damage, retighten
the fabric snow chains after driving
0.3~0.6 miles (0.5~1.0 km).
