Maintenance
The electric motor for the cooling fan
is controlled by engine coolant tem-
perature, refrigerant pressure and
vehicle speed. As the engine coolant
temperature decreases, the electric
motor will automatically shut off. This
is a normal condition. If your vehicle
is equipped with GDI, the electric
motor for the cooling fan may begin
to operate at any time and continue
to operate until you disconnect the
negative battery cable.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, we recommend that you
see an authorized HYUNDAI dealer
for a cooling system inspection.Recommended engine coolant
When adding coolant, use onlydeionized water, distilled water or
soft 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-
based coolant to prevent corrosion
and freezing.
Do not use alcohol or methanol coolant or mix them with the spec-
ified coolant.
Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the
solution.

BRAKE/CLUTCH FLUID
Checking the brake/clutchfluid
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 linings. If
the fluid level is excessively low, have
the brake/clutch system checked by
an authorized HYUNDAI dealer.
✽ ✽
NOTICE
Use only the specified brake/clutch
fluid (refer to “Recommended
Lubricants and Capacities” in chap-
ter 8).
WARNING
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.
CAUTION
Do not allow brake/clutch fluid
to contact the vehicle’s bodypaint, as paint damage willresult.
brake/clutch fluid, which has been exposed to open air foran extended time shouldNEVER be used as its qualitycannot be guaranteed. Itshould be disposed of proper-ly.
Do use the wrong kind of brake/clutch fluid. A few dropsof mineral based oil, such asengine oil, in your brake/clutch system can damagebrake/clutch system parts.

BATTERY
Jump starting can be dangerous if
done incorrectly. Follow the jump
starting procedure in this section to
avoid serious injury or damage to
your vehicle. If in doubt about how to
properly jump start your vehicle, we
strongly recommend that you have a
service technician or towing service
do it for you.
WARNING
To prevent SERIOUS INJURY or
DEATH to you or bystanders,
always follow these precautions
when working near or handling
the battery:Always read and follow
instructions carefully
when handling a battery.Wear eye protection
designed to protect the
eyes from acid splashes.
Keep all flames, sparks,
or smoking materials
away from the battery.
Hydrogen is always present in battery cells,
is highly combustible,
and may explode if ignit-
ed.
Keep batteries out of
reach of children.

TIRES AND WHEELS
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.WARNING
Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of
SERIOUS INJURY or DEATH,
take the following precautions:
Inspect your tires monthly forproper inflation as well as
wear and damage.
The recommended cold tire pressure for your vehicle can
be found in this manual and
on the tire label located on the
driver’s side center pillar.
Always use a tire pressure
gauge to measure tire pres-
sure. Tires with too much or
too little pressure wear
unevenly causing poor han-
dling.
Check the pressure of the spare (if equipped) every time
you check the pressure of the
other tires on your vehicle.
(Continued)
(Continued)
Replace tires that are worn,show uneven wear, or are
damaged. Worn tires can
cause loss of braking effec-
tiveness, steering) control, or
traction.
ALWAYS replace tires with the same size as each tire that
was originally supplied with
this vehicle. Using tires and
wheels other than the recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle’s Anti-Lock Brake System
(ABS) resulting in a serious
accident.

All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar
Recommended cold tire infla-
tion pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold tires” means the
vehicle has not been driven for at
least three hours or driven less than
one mile (1.6 km).
Warm tires normally exceed recom-
mended cold tire pressures by 4 to 6
psi (28 to 41 kPa). Do not release air
from warm tires to adjust the pres-
sure or the tires will be under-inflat-
ed. For recommended inflation pres-
sure, refer to “Tire and Wheels” in
chapter 8.
OMD060012N
WARNING
Recommended pressures must
be maintained for the best ride,
vehicle handling, and minimum
tire wear.
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
could result in loss of vehicle
control resulting in an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
resulting in an accident. This
risk is much higher on hot days
and when driving for long peri-
ods at high speeds.

Maintenance
Check tire inflation pressure
Check your tires, including the spare
tire, once a month or more.
How to check
Use a good quality tire pressure
gauge to check tire pressure. You
can not tell if your tires are properly
inflated simply by looking at them.
Radial tires may look properly inflat-
ed when they are under-inflated.
Remove the valve cap from the tire
valve stem. Press the tire gauge firm-
ly onto the valve to get a pressure
measurement. If the cold tire inflation
pressure matches the recommended
pressure on the tire and loading
information label, no further adjust-
ment is necessary. If the pressure is
low, add air until you reach the rec-
ommended pressure. Make sure to
put the valve caps back on the valve
stems. Without the valve cap, dirt or
moisture could get into the valve
core and cause air leakage. If a valve
cap is missing, install a new one as
soon as possible.If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gauge. Be
sure to put the valve caps back on
the valve stems. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leakage.
If a valve cap is missing, install a new
one as soon as possible.
CAUTION
Under-inflation results in exces-
sive wear, poor handling andreduced fuel economy. Wheeldeformation is also possible.Keep your tire pressures at theproper levels. If a tire frequentlyneeds refilling, have it checkedby an authorized HYUNDAI deal-er.
Over-inflation produces a harshride, excessive wear at the cen-ter of the tire tread, and agreater possibility of damagefrom road hazards.

Tire rotation
To equalize tread wear, HYUNDAI
recommends that the tires be rotated
every 7,500 miles (12,000 km) or
sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check
lug nut tightness (proper torque is
65-79 lb.ft [9-11 kg.m]). Disc brake pads should be inspected
for wear whenever tires are rotated.
✽ ✽
NOTICE
Rotate radial tires that have an
asymmetric tread pattern only from
front to rear and not from right to
left.
OBH078040

Without a spare tire
WARNING
Do not use the compact spare
tire for tire rotation.
Do not mix bias ply and radial ply tires under any circum-
stances. This may cause
unusual handling characteris-
tics that may cause loss of
vehicle control resulting in an
accident.

Maintenance
Wheel alignment and tire bal-
ance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
Tire replacement
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1/16 inch (1.6 mm) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.
CAUTION
Improper wheel weights candamage your vehicle’s alu-minum wheels. Use onlyapproved wheel weights.
OEN076053
Tread wear indicator
WARNING
To reduce the risk of DEATH or
SERIOUS INJURY:
Replace tires that are worn,
show uneven wear, or are dam-
aged. Worn tires can cause loss
of braking effectiveness, steer-
ing control, and traction.
Always replace tires with the
same size as each tire that was
originally supplied with this
vehicle. Using tires and wheels
other than the recommended
sizes could cause unusual han-
dling characteristics, poor vehi-
cle control, or negatively affect
your vehicle’s Anti-Lock Brake
System (ABS) resulting in a
serious accident.
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, HYUNDAI recommends
that tires be replaced after six
(6) years of normal service.
