Interior Care
Interior general precautions
Prevent caustic solutions such as
perfume and cosmetic oil, from con-
tacting the interior parts because
they may cause damage or discol-
oration. If they do contact the interior
parts, wipe them off immediately.
See the instructions for the proper
way to clean vinyl.
Never allow water or other liq-uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them.
When cleaning leather products (steering wheel, seats etc.), use
neutral detergents or low alco-
hol content solutions. If you use
high alcohol content solutions
or acid/ alkaline detergents, the
color of the leather may fade or
the surface may get stripped off.
Cleaning the upholstery andinterior trim
Vinyl (if equipped)
Remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Clean vinyl surfaces with a
vinyl cleaner.
Fabric (if equipped)
Remove dust and loose dirt from fab-
ric with a whisk broom or vacuum
cleaner. Clean with a mild soap solu-
tion recommended for upholstery or
carpets. Remove fresh spots imme-
diately with a fabric spot cleaner. If
fresh spots do not receive immediate
attention, the fabric can be stained
and its color can be affected. Also, its fire-resistant properties can
be reduced if the material is not
properly maintained.
Using anything but recommended
cleaners and procedures may
affect the fabric's appearance and
fire-resistant properties.
Leather (if equipped)
Features of seat leather
- Leather is made from the outerskin of an animal, which goes
through a special process to be
available for use. Since it is a nat-
ural object, each part differs in
thickness or density.
- Wrinkles may appear as a natural result of stretching and shrinking
depending on the temperature
and humidity.
- The seat is made of stretchable fabric to improve comfort.
- The parts contacting the body are curved and the side supporting
area is high which provides driv-
ing comfort and stability.
- Wrinkles may appear naturally from usage. It is not a fault of the
product.

Interior wooden trim
(e.g. wax, coating compound) to
clean the interior wooden trim.
Often wipe the interior wooden trim with a lint-free, clean cloth to main-
tain the unique wooden textures for
a longer period of time.
If you spill beverage (e.g. water, coffee) over the interior wooden
trim, immediately wipe it with
clean, dry cloth.
Sharp objects (e.g. driver, knife), adhesive materials, or tapes
may damage the interior wooden
trim.
Any strong impacts may dam- age the interior wooden trim.
If the coating finish over the interior wooden trim is removed,
moisture may damage or
change wood traits.
If the interior wooden trim is damaged, you may get a splinter
from the wood surface.
Therefore, you should immedi-
ately have the damaged interior
wooden trim replaced by an
authorized retailer of Genesis
Branded products.
Cleaning the seat belt webbing
Clean the belt webbing with any mild
soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the
soap. Do not bleach or re-dye the
webbing because this may weaken
the seat belt.
Cleaning the interior windowglass
If the interior glass surfaces of the
vehicle become fogged (that is, cov-
ered with an oily, greasy or waxy
film), they should be cleaned with
glass cleaner. Follow the directions
on the glass cleaner container.
Do not scrape or scratch the
inside of the rear window. This
may result in damage to the rear
window defroster grid.

*1: Refer to the recommended SAE viscosity numbers on the next page.
*2: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel economy by reducing the amount of fuel
necessary to overcome engine friction. Often, these improvements are difficult to
measure in everyday driving, but in a year’s time, they can offer significant cost and
energy savings.

3: If the API SM & ILSAC GF-4 engine oil is not available in your country, you are able to use API SL & ILSAC GF-3
*
4: If the front/rear differential is submerged, we recommend that you visit an author- ized retailer of Genesis Branded products to replace differential oil.

Recommended SAE Viscosity Number
Always be sure to clean the area around any filler plug, 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 weath-
er operating (engine start and engine oil flowability). Lower viscosity engine
oils can provide better fuel economy and cold weather performance, howev-
er, 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 temper-
ature your vehicle will be operated in before the next oil change. Proceed to
select the recommended oil viscosity from the chart.
NOTICE
*1: For better fuel economy, it is recommended to use the engine oilof a viscosity grade SAE 5W-20 (API SM / ILSAC GF-4
(or above)). However, if the engine oil is not available in your
country, select the proper engine oil using the engine oil viscos-
ity chart.
