The indicator light will blink orange for 10
seconds if there is a malfunction in the
wireless charging system.
In this case, temporarily stop the
charging process, and re-attempt to
charge your smart phone again.
The system warns you with a message on
the LCD display if the smart phone is still
on the wireless charging unit after the
vehicle is turned OFF and the front door
is opened.
For some manufacturer’s smart phones,
the system may not warn you even
though the smart phone is left on the
wireless charging unit. This is due to the
particular characteristic of the smart
phone and not a malfunction of the
wireless charging. Information

[The wireless smart phone charging
system may not support certain smart
phones, which are not verified for the
Qi specification (
).

[When placing your smart phone on the
charging pad, position the phone in the
middle of the mat for optimal charging
performance. If your smart phone is off
to the side, the charging rate may be
less and in some cases the smart phone
may experience higher heat conduction.

[In some cases, the wireless charging
may stop temporarily when the smart
key is used, either when starting the
vehicle or locking/unlocking the doors,
etc.

[When charging certain smart phones,
the charging indicator may not change
to blue when the smart phone is fully
charged.

[The wireless charging process may
temporarily stop, when temperature
abnormally increases inside the wireless
smart phone charging system. The
wireless charging process restarts,
when temperature falls to a certain
level.

[The wireless charging process may
temporarily stop when there is any
metallic item, such as a coin, between
the wireless smart phone charging
system and the smart phone.

your vehicle or the smart phone in any
way.

[Some smart phones may not be able
to charge depending on the internal
structure of the smart phone. If this
occurs, try charging the mobile phone
by moving it to the left or right side of
the wireless charging pad. However, for
some foldable smart phones that have
magnets inside the smart phone, try
charging the smart phone while holding
it close to the left side of the wireless
charging pad.NOTICE

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.

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.

Emergency Situations
10. Start the engine of the assisting
vehicle and let it run at approximately
2,000 RPM for a few minutes. Then
start your vehicle.
11. Keep your vehicle operating for at
least 30 minutes at idle or driving to
assure your battery receives enough
charge to be able to start on its
own after the vehicle is shut off. A
completely discharged battery may
require as long as 60 minutes runtime
to fully recharge it. If the vehicle is run
for less, the vehicle may not restart.
If your vehicle will not start after a few
attempts, it probably requires service.
In this event please seek qualified
assistance. If the cause of your battery
discharging is not apparent, have your
vehicle checked by an authorized retailer
of Genesis Branded products.
Disconnect the jumper cables in the
exact reverse order you connected them:
1. Disconnect the jumper cable from the
black, negative (-) chassis ground of
your vehicle P.
2. Disconnect the other end of the
jumper cable from the black, negative
(-) battery/chassis ground of the
assisting vehicle O.
3. Disconnect the second jumper cable
from the red, positive (+) battery/
jumper terminal of the assisting
vehicle N.
4. Disconnect the other end of the
jumper cable from the red, positive (+)
jumper terminal of your vehicle M.
Information
An inappropriately disposed
battery can be harmful to
the environment and human
health. Dispose of the battery
according to your local law(s) or
regulations.
NOTICE
To prevent damage to your vehicle:
• Only use a 12-volt power supply
(battery or jumper system) to jump
start your vehicle.
• Do not attempt to jump start your
vehicle by push-starting.
WARNING
While jump starting your vehicle, avoid
the positive (+) and negative (-) cables
to come in contact. A spark could cause
personal injury.
WARNING
48 V lithium battery (if equipped)
Do not jump start another vehicle.
The 48 V lithium polymer type battery
installed in your vehicle will be
damaged.
