*1 : Refer to the recommended SAE viscosity numbers on the next page.
*2 : To maintain the best braking performance and ABS/ESC performance, we recommend
that you use fluid that conform to specifications.
*3 : If the front/rear differential is submerged, visit an authorized retailer of Genesis Branded
products to replace the differential oil.
*4 : If the above recommended specification oil is not available, SAE 0W-30 grade synthetic
oil can be used. If mineral oil or semi-synthetic oil is used, it is a severe maintenance
condition in terms of engine oil change

Low washer fluid
This message is displayed if the washer
fluid level in the reservoir is nearly empty.
Have the washer fluid reservoir refilled.
Low fuel
This message is displayed if the fuel tank
is almost out of fuel.

fuel level warning light in the cluster will
come on.
It is recommended to look for the nearest
fueling station and refuel as soon as
possible.
Low engine oil (if equipped)
This warning message is displayed when
the engine oil level should be checked.
If this warning message is displayed,
check the engine oil level as soon as
possible and add engine oil as required.
Slowly pour the recommended oil little
by little into a funnel.
Use only the specified engine oil. (Refer
to "Recommended Lubricants and
Capacities“ section in chapter 2.)
Do not overfill the engine oil. Make sure
the oil level is not above F (Full) mark on
the dipstick.
Information
After adding engine oil, if you travel
approximately 31~62 miles (50~100 km)
after the engine warms up, the warning
message should disappear.

7. If it is near or at L, add enough oil to
bring the level to F.
Use only the specified engine oil (Refer
to “Recommended Lubricants and
Capacities” section in chapter 2).
NOTICE
To prevent damage to your engine:
• Do not overfill with engine oil. Add oil
in small quantities and recheck level
to ensure engine is not overfilled.
• Do not spill engine oil when adding
or changing engine oil. Use a funnel
to help prevent oil from being spilled
on engine components. Wipe off
spilled oil immediately.

Schedule at the beginning of this
chapter.
WARNING
CALIFORNIA PROPOSITION 65
WARNING
Engine oil contains chemicals known to
the State of California to cause cancer,
birth defects and reproductive harm.
Used engine oil may cause irritation or
cancer of the skin if left in contact with
the skin for prolonged periods of time.
Always protect your skin by washing
your hands thoroughly with soap and
warm water as soon as possible after
handling used oil.

Checking the Brake Fluid Level
ORG3090012
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the side
of the reservoir.
Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add the specified brake
fluid to the MAX level. The level will fall
with accumulated mileage. This is a
normal condition associated with the
wear of the brake linings. If the fluid level
is excessively low, have the brake system
checked by an authorized retailer of
Genesis Branded products.
WARNING
If the brake system requires frequent
additions of fluid this could indicate
a leak in the brake system. Have the
vehicle inspected by an authorized
retailer of Genesis Branded products.
WARNING
Do not allow brake fluid to come in
contact with your eyes. If brake fluid
comes in contact with your eyes, flush
your eyes with clean water for at least
15 minutes and get immediate medical
attention.
NOTICE
• Do not allow brake fluid to contact
the vehicle’s body paint, as paint
damage will result.
• Brake fluid, which has been exposed
to open air for an extended time
should NEVER be used as its quality
cannot be guaranteed. It should be
disposed of properly.
• Do not use the wrong kind of brake
fluid. A few drops of mineral based
oil, such as engine oil, in your brake
system can damage brake system
parts.
Information
Use only the specified brake fluid (refer
to “Recommended Lubricants and
Capacities” section in chapter 2).
