Blade Inspection
Contamination of either the wind-
shield or the wiper blades with for-
eign matter can reduce the effective-
ness of the windshield wipers. Common sources of contamination
are insects, tree sap, and hot wax
treatments used by some commer-
cial car washes. If the blades are not
wiping properly, clean both the win-
dow and the blades with a good
cleaner or mild detergent, and rinse
thoroughly with clean water. To prevent damage to the wiper
blades, arms or other compo-
nents, do not:
Use gasoline, kerosene, paint
thinner, or other solvents on or near them.
Attempt to move the wipers manually.
Use non-specified wiper blades.
Information
Commercial hot waxes applied by
automatic car washes have been
known to make the windshield diffi-
cult to clean.
Blade Replacement
When the wipers no longer clean
adequately, the blades may be worn
or cracked, and require replacement.
In order to prevent damage to the hood and the wiper arms, the
wiper arms should only be liftedwhen in the top wiping position.
Always return the wiper arms to the windshield before driving.

When you do not use the vehicle
for a long time in a low tempera-
ture area, disconnect the battery
and keep it indoors.
Always charge the battery fully to prevent battery case damage
in low temperature areas.
NOTICE
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 pres- ent in battery cells, is
highly combustible, and
may explode if ignited.
Keep batteries out of
reach of children.
(Continued)
WARNING (Continued)Batteries contain sulfu-
ric acid which is highly
corrosive. Do not allow
acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush
your eyes with clean water for at
least 15 minutes and get imme-
diate medical attention. If acid
gets on your skin, thoroughly
wash the area. If you feel pain or
a burning sensation, get med-
ical attention immediately.
When lifting a plastic-cased
battery, excessive pressure
on the case may cause battery
acid to leak. Lift with a battery
carrier or with your hands on
opposite corners.
Do not attempt to jump start
your vehicle if your battery is
frozen.
(Continued)
(Continued)
NEVER attempt to recharge
the battery when the vehicle’s
battery cables are connected
to the battery.
The electrical ignition system
works with high voltage.
NEVER touch these compo-
nents with the vehicle ON
( indicator ON) or when
the POWER button is in theON position.

Maintenance
For Best Battery Service
Keep the battery securely mount-ed.
Keep the battery top clean and dry.
Keep the terminals and connec- tions clean, tight, and coated with
petroleum jelly or terminal grease.
Rinse any spilled acid from the bat- tery immediately with a solution of
water and baking soda.
Battery Recharging
Always follow these instruc-
tions when recharging your
vehicle's battery to avoid the
risk of SERIOUS INJURY or
DEATH from explosions or acid
burns:
Before performing mainte-
nance or recharging the bat-
tery, turn off all accessories
and place the POWER buttonto the OFF position.
Keep all flames, sparks, or
smoking materials away from
the battery.
Always work outdoors or in an area with plenty of ventilation.
Wear eye protection when
checking the battery during
charging.
The battery must be removed
from the vehicle and placed ina well ventilated area.
(Continued)
WARNING
OAEE076007 (Continued)
Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin boiling violently.
The negative battery cable
must be removed first and
installed last when the battery
is disconnected. Disconnect
the battery charger in the fol-
lowing order:
(1) Turn off the battery charg-
er main switch.
(2) Unhook the negative clamp from the negative
battery terminal.
(3) Unhook the positive clamp from the positive batteryterminal.
Always use a genuine
HYUNDAI approved battery
when you replace the battery.

Maintenance
By jump starting
After a jump start from a good bat-
tery, drive the vehicle for 20-30 min-
utes before it is shutoff. The vehicle
may not restart if you shut it off
before the battery had a chance to
adequately recharge. See "Jump
Starting" in chapter 6 for more infor-
mation on jump starting procedures.Information An inappropriately disposedbattery can be harmful to
the environment and human
health.
Dispose the battery according to your
local law(s) or regulation.
Reset Features
Some items need to be reset after
the battery has been discharged or
the battery has been disconnected.

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.
(Continued)Replace tires that are worn,
show uneven wear, or are dam-
aged. Worn tires can cause
loss of braking effectiveness,
steering) control, or traction.
ALWAYS replace tires with the
same size as each tire that
was originally supplied with
this vehicle. Using tires andwheels 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 seriousaccident.
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 for
proper inflation as well as
wear and damage.
The recommended cold tire
pressure for your vehicle can
be found in this manual and onthe tire label located on the dri-
ver’s side center pillar. Always
use a tire pressure gauge to
measure tire pressure. Tires
with too much or too little
pressure wear unevenly caus-ing poor handling.
Check the pressure of the
spare every time you checkthe pressure of the other tires
on your vehicle.
(Continued)
WARNING

7-24
Maintenance
All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.
Recommended Cold Tire Inflation 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 than1.6 km (1 mile).
Warm tires normally exceed recom-
mended cold tire pressures by 28 to
41 kPa (4 to 6 psi). 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" inchapter 8.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 andother 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.
