2021 GENESIS G80 stop start

Maintenance
9-58
Consult an authorized retailer of
Genesis Branded products to replace
most vehicle light bulbs. It is difficult
to replace vehicle light bulbs because
other parts of the vehicle must be
removed before you can get to the bulb.
This is especially true for removing the
headlamp assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to the
vehicle.
WARNING
• Prior to working on a light, depress
the foot brake, shift to P (Park), apply
the parking brake, press the Engine
Start/Stop button to the OFF position
and take the key with you when
leaving the vehicle to avoid sudden
movement of the vehicle and to
prevent possible electric shock.
• Be aware the bulbs may be hot and
may burn your fingers.
NOTICE
Be sure to replace the burned-out bulb
with one of the same wattage rating.
Otherwise, it may cause damage to the
fuse or electrical wiring system.
NOTICE
To prevent damage, do not clean the
headlamp lens with chemical solvents
or strong detergents.
Information
The headlamp and tail lamp lenses could
appear frosty if the vehicle is washed after
driving or the vehicle is driven at night in
wet weather. This condition is caused by
temperature difference between the lamp
inside and outside and, it does not indicate
a problem with your vehicle. When
moisture condenses in the lamp, it will be
removed after driving with the headlamp
on. The removable level may differ
depending on lamp size, lamp position
and environmental condition. However, if
moisture is not removed, have the vehicle
inspected by an authorized retailer of
Genesis Branded products.
Information
• A normally functioning lamp may
flicker momentarily to stabilize the
vehicle’s electrical control system.
However, if the lamp goes out after
flickering momentarily, or continues to
flicker, have the system checked by an
authorized retailer of Genesis Branded
products.
• The parking lamp may not turn on
when the parking lamp switch is turned
on, but the parking lamp and headlamp
switch may turn on when the headlamp
switch is turned on. This may be caused
by network failure or vehicle electrical
control system malfunction. If this
occurs, have the system checked by an
authorized retailer of Genesis Branded
products.
Information
The headlamp aiming should be adjusted
after an accident or after the headlamp
assembly is reinstalled at an authorized
retailer of Genesis Branded products.

3. Exhaust Emission Control
System
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performance.
When the engine starts or fails to start,
excessive attempts to restart the engine
may cause damage to the emission
system.
Engine exhaust (carbon monoxide)
precautions
• Carbon monoxide can be present
with other exhaust fumes. If you smell
exhaust fumes of any kind in your
vehicle, drive with all the windows
fully open. Have your vehicle checked
and repaired immediately.
WARNING
Engine exhaust gases contain carbon
monoxide (CO). Though colorless and
odorless, it is dangerous and could be
lethal if inhaled. Follow the instructions
on this page to avoid CO poisoning.
WARNING
CALIFORNIA PROPOSITION 65
WARNING
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the
interior furnishings in a vehicle, contain
or emit chemicals known to the State
of California to cause cancer and
birth defects and reproductive harm.
In addition, certain fluids contained
in vehicles and certain products of
component wear contain or emit
chemicals known to the State of
California to cause cancer and birth
defects or other reproductive harm.
Do not operate the engine in confined
or closed areas (such as garages) any
more than what is necessary to move the
vehicle in or out of the area.
• When the vehicle is stopped in an
open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to draw
outside air into the vehicle.
• Never sit in a parked or stopped
vehicle for any extended time with the
engine running.
• When the engine stalls or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission control system.
