Recommended SAE Viscosity Number
CAUTION
Always be sure to clean the area around any filler cap, drain plug, or dipstick before
checking or draining any lubricant. This is especially important in dusty or sandy
areas and when the vehicle is used on unpaved roads. Cleaning the plug and dipstick
areas will prevent dirt and grit from entering the engine and other mechanisms that
could be damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather
operating (engine start and engine oil flowability). Lower viscosity engine oils can
provide better fuel economy and cold weather performance, however, higher viscosity
engine oils are required for satisfactory lubrication in hot weather. Using oils of any
viscosity other than those recommended could result in engine damage.
When choosing an oil, consider the range of temperature your vehicle will be operated
in before the next oil change. Proceed to select the recommended oil viscosity from
the chart.

Cabin air filter
OHI048581L
A : Outside air,
B : Recirculated air,
C : Climate control air filter,
D : Blower,
E : Evaporator core,
F : Heater core
The cabin air filter is installed behind
the glove box. It filters the dust or other
pollutants that enter the vehicle through
the heating and air conditioning system.
We recommend that the cabin air filter
be replaced by an authorized retailer of
Genesis Branded products according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
have the system inspected at an
authorized retailer of Genesis Branded
products.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also reduces the
performance of the air conditioning
system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized retailer of Genesis Branded
products.
NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
NOTICE

[The refrigerant system should only
be serviced by trained and certified
technicians to insure proper and safe
operation.

[The refrigerant system should be
serviced in a well-ventilated place.

[The air conditioning evaporator
(cooling coil) shall never be repaired
or replaced with one removed from
a used or salvaged vehicle and new
replacement MAC evaporators shall
be certified (and labeled) as meeting
SAE Standard J2842.

WARNING
Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and
death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows
immediately. Exposure to CO can cause unconsciousness and death by asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the
oil or for any other purpose. If you hear a change in the sound of the exhaust or if you
drive over something that strikes the underneath side of the vehicle, have the exhaust
system checked as soon as possible by an authorized retailer of Genesis Branded
products.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous
practice. Run the engine only long enough to start the engine and to move the vehicle
out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the
vehicle, be sure to do so only in an open area with the air intake set at “Fresh” and fan
control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air intakes
located in front of the windshield clear of snow, ice, leaves, or other obstructions.
If you must drive with the trunk open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at “Fresh”, the air flow control at “Floor” or “Face”, and the fan
control set to high.

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.
