Owner Maintenance Schedule
When you stop for fuel:
• Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windshield washer fluid
level.
Check the for low or under-inflated
tires.
While operating your vehicle:
Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly
turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the
operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmission/
dual clutch transmission P (Park)
function. Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the engine
coolant reservoir.
Check the operation of all exterior
lights, including the brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all
tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts. Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.

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 con-
ditions, 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 peri-
odically 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, oper-
ate 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 dam-
age. Have an authorized HYUNDAI
dealer replace any damaged or leak-
ing parts immediately.
Vapor Hose and Fuel Filler
Cap
The vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure a new vapor
hose or fuel filler cap is correctly
replaced.
Vacuum Crankcase Ventilation
Hoses (if equipped)
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to ensure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.

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.
Engine Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic Transmission Fluid
(if equipped)
Automatic transmission fluid should
not be checked under normal usage
conditions. But in severe conditions,
the fluid should be changed at an
authorized HYUNDAI dealer in
accordance to the scheduled mainte-
nance at the beginning of this chap-
ter.
Automatic transmission fluid
color is red when new.
As the vehicle is driven, the auto-
matic transmission fluid will begin
to look darker. This is a normal
condition and you should not
judge the need to replace the fluid
based upon the changed color.
Dual Clutch Transmission
Fluid (if equipped)
Inspect the dual clutch transmission
fluid according to the maintenance
schedule.
Manual Transmission Fluid
(if equipped)
Inspect the manual transmission
fluid according to the maintenance
schedule.
NOTICE
The use of a non-specified fluid
could result in transmission
malfunction and failure. Use
only the specified automatic
transmission fluid (refer to
"Recommended Lubricants and
Capacities" in chapter 8).

The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season
and before traveling to a colder cli-
mate.
When the engine overheats from
low engine coolant, suddenly
adding engine coolant may
cause cracks in the engine. To
prevent damage, add engine
coolant slowly in small quanti-
ties.
Do not drive with no engine
coolant. It may cause water
pump failure and engine seizure,
etc.Checking the Engine Coolant
Level
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.The coolant level should be filled
between the F and the L marks on
the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring the
level to the F mark, but do not overfill.
If frequent additions are required, see
an authorized HYUNDAI dealer for a
cooling system inspection.
Recommended engine coolant
When adding coolant, use only dis-
tilled (deionized) water for your
vehicle and never mix hard water in
the coolant filled at the factory.
An improper coolant mixture can
result in severe malfunction or
engine damage.
The engine in your vehicle has alu-
minum engine parts and must be
protected by an ethylene-glycol
with phosphate based coolant to
prevent corrosion and freezing.
Do not use alcohol or methanol
coolant or mix them with the spec-
ified coolant.

Maintenance
Do not use a solution that contains
more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the
solution.
For mixing percentage, refer to the
following table:
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
-35°C (-31°F) and higher.

Checking the brake/clutch
Fluid Level
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/clutch fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutch
fluid contamination.If the level is low, add the specified
brake/clutch fluid to the MAX level.
The level will fall with accumulated
mileage. This is a normal condition
associated with the wear of the
brake/clutch linings. If the fluid level
is excessively low, have the brake/
clutch system checked by an author-
ized HYUNDAI dealer. Do not allow brake/clutch fluid
to contact the vehicle’s body
paint, as paint damage will
result.
Brake/clutch 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 dis-
posed of properly.
Do not use the wrong kind of
brake/clutch fluid. A few drops
of mineral based oil, such as
engine oil, in your brake/clutch
system can damage system
parts.
Information
Use only the specified brake/clutch
fluid (refer to "Recommended
Lubricants and Capacities" in chap-
ter 8).
i
NOTICE
If the brake/clutch system
requires frequent additions of
fluid this could indicate a leak in
the brake/clutch system. Have
the vehicle inspected by an
authorized HYUNDAI dealer.
WARNING
Do not allow brake/clutch fluid
to come in contact with your
eyes. If brake/clutch fluid comes
in contact with your eyes, flush
your eyes with clean water for at
least 15 minutes and get imme-
diate medical attention.

Checking the Washer Fluid
Level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
Checking the Parking Brake
Check the stroke of the parking
brake by counting the number of
"clicks" heard while fully applying it
from the released position. Also, the
parking brake alone should securely
hold the vehicle on a fairly steep
grade. If the stroke is more or less
than specified, have the parking
brake adjusted by an authorized
HYUNDAI dealer.

To prevent serious injury or
death, take the following safety
precautions when using washer
fluid:
Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
Engine coolant can severely
obscure visibility when sprayed
on the windshield and may
cause loss of vehicle control
resulting in an accident or dam-
age to paint and body trim.
Do not allow sparks or flames
to contact the washer fluid or
the washer fluid reservoir.
Washer fluid may contain alco-
hol and can be flammable.
Do not drink washer fluid and
avoid contact with skin.
Washer fluid is harmful to
humans and animals.
Keep washer fluid away from
children and animals.
