Checking the Engine Oil Level
Engine oil is used for lubricating,
cooling, and operating various hydraulic
components in the engine. Engine oil
consumption while driving is normal,
and it is necessary to check and refill the
engine oil regularly. Also, check and refill
the oil level within the recommended
maintenance schedule to prevent
deterioration of oil performance.
Check the engine oil following the below
procedure.
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on the level
ground in P (Park) with the parking
brake set and the wheels blocked.
3. Turn the engine on and warm
the engine up until the coolant
temperature reaches a constant
normal temperature.
4. Turn the engine off, remove the oil
filler cap and pull the dipstick out.
Wait for 15 minutes for the oil to return
to the oil pan.
5. Wipe the dipstick clean and re-insert
it fully.

6. Pull the dipstick out again and check
the level. The level should be between
F (Full) and L (Low).
ORS091003
7. If the oil level is below 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 spill engine oil when adding
or changing engine oil. Wipe off
spilled oil immediately.

[The engine oil consumption may
increase while you break in a new
vehicle and it will be stabilized after
driving 4,000 miles (6,000 km).

[The engine oil consumption can be
affected by driving habits, climate
conditions, traffic conditions,
oil quality, etc. Therefore, it is
recommended that you inspect the
engine oil level regularly and refill it
if necessary.

Checking the Brake Fluid Level
ORS091006
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 let brake fluid enter into your
eyes. If brake fluid gets in 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 it will
result in paint damage.

[NEVER use brake fluid which has
been exposed to open air for an
extended time, as its quality cannot
be guaranteed. It should be disposed
of properly.

[Do not use the wrong type 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).
