To help achieve proper engine and powertrain performance and durability, use only
lubricants of the proper quality. The correct lubricants also help promote engine
efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.

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” 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 6,000 km (4,000 miles).
• 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.

The engine oil change interval is set
for the purpose of preventing oil
deterioration, and is not related the
amount of oil consumption. so, check
and refill the amount of the oil regularly.

Checking the Brake Fluid Level
ODN8089005
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 HYUNDAI
dealer.
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
HYUNDAI dealer.
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” in chapter 2).
