2020 GENESIS G90 check engine light

Using All Wheel Drive (AWD)
The All Wheel Drive (AWD) system
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.
If the system determines there is a
need for four wheel drive, the
engine's driving power is distributed
to all four wheels automatically.

If the AWD warning light ( )
stays on the instrument cluster,
your vehicle may have a mal-
function with the AWD system.
When the AWD warning light
( ) illuminates have your
vehicle checked by an author-
ized retailer of Genesis Branded
products as soon as possible.
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 cor- nering or turning.
Do not make quick steering wheel movements, such as
sharp lane changes or fast,
sharp turns.
The risk of a rollover is great- ly increased if you lose con-
trol 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.
Always drive safely and use caution when driving an AWD
vehicle.
WARNING

Information
• Do not drive in water if the level ishigher than the bottom of the vehi-
cle.
• 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 return.
• Shorten your scheduled mainte- nance interval if you drive in off-
road conditions such as sand, mud
or water (see "Maintenance Under
Severe Usage Conditions" in chap-
ter 7).
• Make sure that an AWD vehicle is towed by flatbed tow truck.
For safe AWD operation
Before driving
Make sure all passengers arewearing seat belts.
Sit upright and adjust the steering wheel to a position comfortable for
you to drive.
Driving on snow-covered or icy
roads
Start off slowly by applying theaccelerator pedal gently.
Use of snow tires is recommended. For more information on Snow
Tires refer to "Winter Driving" in
this chapter.
Keep sufficient distance between your vehicle and the vehicle in front
of you.
When approaching a stop sign or stop light, release the accelerator
pedal to provide engine braking
during deceleration.
Avoid speeding, rapid acceleration, sudden brake applications, and
sharp turns to prevent skids.

The severe weather conditions of winter quickly wear out tires and cause
other problems. To minimize winter driving problems, you should take the fol-
lowing suggestions:
Snow or Icy Conditions
You need to keep sufficient distance between your vehicle and the vehicle in
front of you.
Apply the brakes gently. Speeding, rapid acceleration, sudden brake applica-
tions, and sharp turns are potentially very hazardous practices. During decel-
eration, use engine braking to the fullest extent. Sudden brake applications on
snowy or icy roads may cause the vehicle to skid.
To drive your vehicle in deep snow, it may be necessary to use snow tires or
to install tire chains on your tires.
Always carry emergency equipment. Some of the items you may want to carry
include tire chains, tow straps or chains, a flashlight, emergency flares, sand,
a shovel, jumper cables, a window scraper, gloves, ground cloth, coveralls, a
blanket, etc.
Snow tires
We recommend 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.
If you mount snow tires on your vehicle, make sure to use the same inflation
pressure as the original tires. However, if you mount 245/45R19 size tire on
the rear, the tire inflation pressure should maintain 35psi. 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 road may not be as high as your
vehicle's original equipment tires. Check with the tire dealer for maximum
speed recommendations.
Information
Do not install studded tires without first checking local, state and municipal reg-
ulations for possible restrictions against their use.

If you Have a Flat Tire While
Driving
If a tire goes flat while you are driv-
ing:
Take your foot off the accelerator
pedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-
ately or attempt to pull off the road
as this may cause loss of vehicle
control resulting in an accident.
When the vehicle has slowed to
such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm, level
ground. If you are on a divided
highway, do not park in the median
area between the two traffic lanes.
When the vehicle is stopped, press the hazard warning flasher button,
shift the gear to P (Park), apply the
parking brake, and press the
Engine Start/Stop button to the
OFF position.
Have all passengers get out of the vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
When changing a flat tire, follow the instructions provided later in
this chapter.If the Engine Doesn't Turn
Over or Turns Over Slowly
Be sure to shift the gear to N(Neutral) or P (Park). The engine
starts only when the gear is in N
(Neutral) or P (Park).
Turn on the interior light. If the light dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to
start it. This could cause damage to
your vehicle. See instructions for
"Jump Starting" provided in this
chapter.
Push or pull starting the vehicle
may cause the catalytic converter
to overload which can lead to
damage to the emission control
system.
If the Engine Turns Over
Normally but Doesn't Start
Check the fuel level and add fuel if
necessary.
If the engine still does not start, have
your vehicle checked by an author-
ized retailer of Genesis Branded
products.

Indicator
When the tire pressure monitoring
system warning indicators are illumi-
nated and the warning message is
displayed on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The LCD posi-
tion indicator will indicate which tire
is significantly under-inflated by illu-
minating the corresponding position
light.
If any of your tire pressures are indi-
cated as being low, immediately
reduce your speed, avoid hard cor-
nering, and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle’s placard or tire inflation pressure
label located on the driver's side cen-
ter pillar outer panel.
If you cannot reach a service station
or if the tire cannot hold the newly
added air, replace the low pressure
tire with the spare tire.
The Low Tire Pressure LCD position
indicator will remain on and the
TPMS Malfunction Indicator may
blink for one minute and then remain
illuminated until you have the low
pressure tire repaired and replaced
on the vehicle.

Owner Maintenance Schedule
When you stop for fuel:
• Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windshield washer fluid level.
Check the tire for low or under- inflated tires.
While operating your vehicle:
Note any changes in the sound ofthe exhaust or any smell of exhaust
fumes in the vehicle.
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmission P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.

Battery Recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged
in a short time (because, for exam-
ple, the headlights or interior lights
were left on while the vehicle was
not in use), recharge it by slow
charging (trickle) for 10 hours.
If the battery gradually discharges because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours.
AGM battery
Absorbent Glass Matt (AGM) batteries are maintenance-free
and we recommend that the
AGM battery be serviced by an
authorized retailer of Genesis
Branded products. For charging
your AGM battery, use only fully
automatic battery chargers that
are specially developed for AGM
batteries.
When replacing the AGM bat- tery, we recommend that you
use parts for replacement from
an authorized retailer of Genesis
Branded products.
Do not open or remove the cap on top of the battery. This may
cause leaks of internal elec-
trolyte that could result in
severe injury.
NOTICE
Always follow these instruc-
tions when recharging your
vehicle's battery to avoid the
risk of SERIOUS INJURY or
DEATH from explosions or acid
burns:
Before performing mainte-nance or recharging the bat-
tery, turn off all accessories
and press the Engine Start/
Stop button to the OFF posi-
tion.
