2021 GENESIS G90 air condition

• The system may turn off if inter-
fered by electromagnetic waves.
• Always keep the rear view camera
and the ultrasonic sensors clean.
• Do not use any cleanser contain-
ing acid or alkaline detergents
when cleaning the rear view cam-
era lens. Use only a mild soap or
neutral detergent, and rinse thor-
oughly with water.
• NEVER disassemble the rear
view camera or the ultrasonic
sensor components or apply any
impact on the rear view camera or
the ultrasonic sensor compo-
nents.
• Do not apply unnecessary force
on the rear view camera or the
ultrasonic sensors. The system
may not operate properly if the
rear view camera or the ultrason-
ic sensor(s) is forcibly moved out
of proper alignment. We recom-
mend that you immediately have
the vehicle inspected by an
authorized retailer of Genesis
Branded products.
• Do not spray the rear view cam-
era or the ultrasonic sensors or
their surrounding area directly
with a high pressure washer.
Shock applied from high pres-
sure water may cause the device
to malfunction.
• The system may not work proper-
ly if the bumper has been dam-
aged, or if the rear bumper has
been replaced or repaired.
• Do not apply foreign objects,
such as a bumper sticker or a
bumper guard, near the camera
or sensors or apply paint to the
bumper. Doing so may adversely
affect the performance of the sys-
tem.
Warning message
Rear camera error or blockage/
Parking sensor error or blockage
This warning message may appear
when:
- The rear view camera or the ultra-
sonic sensor(s) is blocked by dirt,
snow, or a foreign object.
- There is inclement weather, such
as heavy snow, rain, etc.
If any of these conditions occur, the
system may turn off automatically or
not operate properly.
When the warning message is dis-
played in the cluster, make sure that
the rear view camera and the rear
ultrasonic sensors are clean.

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.
To prevent damage to your vehi-
cle:
• 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.
Jump starting procedure
Information
Your vehicle has a battery in the trunk
compartment, but when you jump
start your vehicle, use the jumper ter-
minal in the engine compartment.
1. Position the vehicles close enough
that the jumper cables will reach,
but do not allow the vehicles to
touch.
2. Avoid fans or any moving parts in
the engine compartment at all
times, even when the vehicles are
turned off.
3. Turn off all electrical devices such
as radios, lights, air conditioning,
etc. Put the vehicles in P (Park)
and set the parking brakes. Turn
both vehicles OFF.
4. Open the engine hood.5. Open the small service cover with
a screwdriver.
6. Remove the engine compartment
fuse box cover.
7. Connect the jumper cables in the
exact sequence shown in the illus-
tration. First connect one jumper
cable to the red, positive (+)
jumper terminal of your vehicle (1).
8. Connect the other end of the
jumper cable to the red, positive
(+) battery/jumper terminal of the
assisting vehicle (2).

If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1. Pull off the road and stop as soon
as it is safe to do so.
2. Shift the gear to P (Park) and set
the parking brake. If the air condi-
tioning is ON, turn it OFF.
3. If engine coolant is running out
under the vehicle or steam is com-
ing out from the hood, stop the
engine. Do not open the hood until
the coolant has stopped running
or the steaming has stopped. If
there is no visible loss of engine
coolant and no steam, leave the
engine running and check to be
sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.4. Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (If the air conditioning had
been in use, it is normal for cold
water to be draining from it when
you stop.)
5. If engine coolant is leaking out,
stop the engine immediately and
call the nearest authorized retailer
of Genesis Branded products for
assistance.
IF THE ENGINE OVERHEATS
While the engine is
running, keep hands,
clothing and tools
away from the moving
parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
WARNING

6-20
What to do in an emergency
When driving with the compact spare
tire mounted to your vehicle:
• Check the tire pressure after
installing the compact spare tire.
The compact spare tire should be
inflated to 60 psi (420 kPa).
• Do not take this vehicle through an
automatic car wash while the com-
pact spare tire is installed.
• Do not use the compact spare tire
on any other vehicle because this
tire has been designed especially
for your vehicle.
• The compact spare tire's tread life
is shorter than a regular tire.
Inspect your compact spare tire
regularly and replace worn com-
pact spare tires with the same size
and design, mounted on the same
wheel.
• Do not use more than one compact
spare tire at a time.
Information
When the original tire and wheel are
repaired and reinstalled on the vehi-
cle, the lug nut torque must be set cor-
rectly. The correct lug nut tightening
torque is 79~94 lbf·ft (11~13 kgf·m).
To prevent damaging the compact
spare tire and your vehicle:
• Drive slowly enough for the road
conditions to avoid all hazards,
such as a potholes or debris.
• Avoid driving over obstacles.
The compact spare tire diameter
is smaller than the diameter of a
conventional tire and reduces
the ground clearance approxi-
mately 1 inch (25 mm).
• Do not use tire chains on the
compact spare tire. Because of
the smaller size, a tire chain will
not fit properly.
• Do not use the compact spare
tire on any other wheels, nor
should standard tires, snow
tires, wheel covers or trim rings
be used with the compact spare
wheel.

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 of
the 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 engine
coolant 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.
