System Malfunction
OJWEV061048L
Check Electronic Suspension
When Electronically Controlled
Suspension with Road Preview is not
working properly, this warning message
will appear on the cluster LCD display. If
this occurs, have the system inspected
by an authorized retailer of Genesis
Branded products.
NOTICE
If the battery level is high or low,
Electronically Controlled Suspension
with Road Preview may not work
temporarily to protect the system. If this
occurs, ‘Check Electronic Suspension’
warning message will appear.
Limitations of the System
Electronically Controlled Suspension
with Road Preview always operates
while driving according to the vehicle’s
movement, and the preview function
starts to work when the front view
camera detects road conditions such as
speed bumps. Therefore, the preview
function is limited when there is an
extreme condition that the front view
camera may not work normally. In this
case, the electronic control suspension
function operates without the preview
function in accordance with vehicle
movement.

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.

Idle Stop and Go helps reduce fuel
consumption by automatically shutting
down the engine, when the vehicle is
at a standstill (for example, red stop
light, stop sign, and traffic jam) subject
to certain prerequisite conditions being
satisfied as listed below.
The engine is automatically started upon
satisfying the starting conditions.
ISG system is always active, when the
engine is running.
Information
When the engine is automatically started
by ISG system, warning lights (for
example, ABS, ESC, ESC OFF, MDPS,
and parking brake warning light) may
illuminate for a few seconds due to low
battery voltage.
However, it does not indicate a
malfunction with ISG system.
ISG System Operation

Winter Precautions
Use high quality ethylene glycol coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 9. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. The
battery charging level can be checked by
an authorized retailer of Genesis Branded
products or in a service station.
Change to “winter weight” oil if
necessary
In some regions during winter, it is
recommended to use the “winter
weight” oil with lower viscosity. In
addition, replace the engine oil and filter
if it is close to the next maintenance
interval. Fresh engine oil ensures
optimum engine operation during the
winter months. For further information,
refer to chapter 2. When you are not sure
about a type of winter weight oil, consult
an authorized retailer of Genesis Branded
products.Check spark plugs and ignition system
Inspect the spark plugs, as specified in
chapter 9. If necessary, replace them.
Also check all ignition wirings and
components for any cracks, wear-out,
and damage.
To prevent locks from freezing
To prevent the locks from being frozen,
spray approved de-icing fluid or glycerin
into key holes. When a lock opening is
already covered with ice, spray approved
de-icing fluid over the ice to remove it.
When an internal part of a lock freezes,
try to thaw it with a heated key. Carefully
use the heated key to avoid an injury.
Use approved window washer anti-
freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as specified
on the window washer container.
Window washer anti-freeze solution is
available from an authorized retailer of
Genesis Branded products, and most
vehicle accessory outlets. Do not use
engine coolant or other types of anti-
freeze solution, to prevent any damage
to the vehicle paint.
Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when there
is an accumulation of snow or ice around
or near the rear brakes or if the brakes
are wet. When there is the risk that your
parking brake may freeze, temporarily
apply it with the gear in P (Park). Also,
block the rear wheels in advance, so the
vehicle may not roll. Then, release the
parking brake.
