Engine Oil and Filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the vehicle
is being driven in severe conditions,
more frequent oil and filter changes are
required.
Drive Belts
Inspect all drive belts for evidence
of cuts, cracks, excessive wear or oil
saturation and replace if necessary. Drive
belts should be checked periodically
for proper tension and adjusted as
necessary.
Fuel Filter
A clogged-up fuel filter may limit the
vehicle driving speed, damage the
emission system, and cause the hard
starting. When a considerable amount
of foreign substances are accumulated
in the fuel tank, the fuel filter should be
replaced.
Upon installing a new fuel filter, operate
the engine for several minutes, and
check the connections for any leakages.
Fuel filters should be installed by an
authorized HYUNDAI dealer.
Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
Have an authorized HYUNDAI dealer
replace any damaged or leaking parts
immediately.
Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
a new vapor hose or fuel filler cap is
correctly replaced.
Air Cleaner Filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark Plugs
Make sure to install new spark plugs of
the correct heat range.
Cooling System
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.

Checking the Engine Oil Level
1. Follow all of the oil manufacturer’s
precautions.
2.
Be sure the v

ehicle is on the level
ground in P (Park) with the parking
brake set. If possible, block the
wheels.
3.
Turn the engine on and allo

w the
engine to reach normal operating
temperature.
4.
Turn the engine o

ff and wait about
five minutes for the oil to return to the
oil pan.
5.
Pull the dipstick out, wipe it clean, and
r

e-insert it fully.
OCN7080066L
„„Smartstream G2.0
6. Pull the dipstick out again and check
the le vel. The level should be between
F and L.
OCN7080068L
„„Smartstream G2.0
7. If it is near or at L, add enough oil t o
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 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.
Checking the Engine Oil and
Filter
Have engine oil and filter changed by an
authorized HYUNDAI dealer according
to the Maintenance 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.

Maintenance
9-18
Checking the brake fluid level
OCN7080006
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 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, we
recommend that the system be checked
by an authorized HYUNDAI dealer.
Information
Use only the specified brake fluid. Refer to
“Recommended lubricants and capacities”
in chapter 2.
Information
Before removing the brake/clutch filler
cap, read the warning on the cap.
Information
Clean the filler cap before removing. Use
only DOT4 brake fluid from a sealed
container.
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.
• Don’t put in the wrong kind of fluid. A
few drops of mineralbased oil, such
as engine oil, in your brake system
can damage system parts.
• To maintain the best braking
performance and ABS/ESC
performance, we recommend that
you use genuine brake fluid that
conform to specifications.

Filter replacement
OCN7090010N
The air cleaner filter can be cleaned for
inspection using compressed air. Do not
attempt to wash or to rinse it, as water
will damage the filter. If soiled, the air
cleaner filter must be replaced.
OCN7090011N
1. Loosen the air cleaner cover attaching
clip (1) and open the cover.
OCN7090012N
2. Replace the air cleaner filter.
OCN7080088N
3. Insert the air cleaner cov er in the
hinge (2) and engage the clip (1) after
closing the cover.
4.
Check that the co

ver is firmly
installed.
Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the element
more often than the usual recommended
intervals (refer to “Maintenance Under
Severe Usage Conditions” in this chapter).
NOTICE
• Do not drive with the air cleaner filter
removed. This will result in excessive
engine wear.
• When removing the air cleaner filter,
be careful that dust or dirt does not
enter the air intake, or damage may
result.
• Use HYUNDAI genuine parts. Use of
non-genuine parts could damage the
engine.
