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 the
ON position.

Maintenance
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.
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.

Wash hands after handling.
WARNING
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 button
to 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.

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 disposed
battery 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.

(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 battery
terminal.
Always use a genuine
HYUNDAI approved battery
when you replace the battery.

Maximum Inflation Pressure
The maximum air pressure to which
a cold tire may be inflated. The max-
imum air pressure is molded onto the
sidewall.
Maximum Load Rating
The load rating for a tire at the maxi-
mum permissible inflation pressure
for that tire.
Maximum Loaded Vehicle
Weight
The sum of curb weight; accessory
weight; vehicle capacity weight; and
production options weight.
Normal Occupant Weight
The number of occupants a vehicle
is designed to seat multiplied by 150
pounds (68 kg).
Occupant Distribution
Designated seating positions.
Outward Facing Sidewall
An asymmetrical tire has a particular
side that faces outward when mount-
ed on a vehicle. The outward facing
sidewall bears white lettering or
bears manufacturer, brand, and/or
model name molding that is higher or
deeper than the same moldings on
the inner facing sidewall.
Passenger (P-Metric) tire
A tire used on passenger cars and
some light duty trucks and multipur-
pose vehicles.
Ply
A layer of rubber-coated parallel
cords.
Pneumatic tire
A mechanical device made of rubber,
chemicals, fabric and steel or other
materials, that, when mounted on an
automotive wheel provides the trac-
tion and contains the gas or fluid that
sustains the load.
Pneumatic options weight
The combined weight of installed
regular production options weighing
over 5 lb. (2.3 kg) in excess of the
standard items which they replace,
not previously considered in curb
weight or accessory weight, includ-
ing heavy duty breaks, ride levelers,
roof rack, heavy duty battery, and
special trim.
Recommended Inflation
Pressure
Vehicle manufacturer's recommend-
ed tire inflation pressure as shown
on the tire placard.

A vehicle's electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver's side panel
bolster, the other in the motor com-
partment near the battery.If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not
work, first check the driver's side
fuse panel. Before replacing a blown
fuse, turn the vehicle and all switch-
es off, and then disconnect the neg-
ative battery cable. Always replace a
blown fuse with one of the same rat-
ing.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized
HYUNDAI dealer.
Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and multi fuse for higher
amperage ratings.
i
NEVER replace a fuse with any-
thing but another fuse of the
same rating.
A higher capacity fuse could
cause damage and possibly
cause a fire.
Do not install a wire or alu-
minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
possibly a fire.
