B260H02A-AAT
Parking Brake/Low Brake
Fluid Level Warning Light
Your Hyundai is equipped with dual-di-
agonal braking systems. This means you
still have braking on two wheels even if
one of the dual systems should fail. With
only one of the dual systems working,
more than normal pedal travel and greater
pedal pressure are required to stop the
car. Also, the car will not stop in as short a
distance with only half of the brake system
working. If the brakes fail while you are
driving, shift to a lower gear for additional
engine braking and stop the car as soon as
it is safe to do so.
WARNING:
If you suspect brake trouble, have your
brakes checked by a Hyundai dealer as
soon as possible. Driving your car with
a problem in either the brake electrical
system or brake hydraulic system is
dangerous, and could result in a serious
injury or death.
Warning Light OperationThe parking brake/brake fluid level warn-
ing light should come on when the parking
brake is applied and the ignition switch is
turned to "ON" or "START". After the engine
is started, the light should go out when the
parking brake is released.
If the parking brake is not applied, the
warning light should come on when the
ignition switch is turned to "ON" or "START",
then go out when the engine starts. If the
light comes on at any other time, you should
slow the vehicle and bring it to a complete
stop in a safe location off the roadway.
The brake fluid level warning light indi-
cates that the brake fluid level in the brake
master cylinder is low and hydraulic brake
fluid conforming to DOT 3 or DOT 4 speci-
fications should be added. After adding
fluid, if no other trouble is found, the car
should be immediately and carefully driven
to a Hyundai dealer for inspection. If further
trouble is experienced, the vehicle should
not be driven at all but taken to a dealer by
a professional towing service.

CAUTION:
When replacing a fusible link, never use
anything but a new fusible link with the
same or lower amperage rating. Never
use a piece of wire or a higher-rated
fusible link. This could result in serious
damage and create a fire hazard. The parking brake pedal should be
checked periodically for proper stroke. If
you feel loose in the parking brake pedal
when the parking brake is engaged, have
your parking brake adjusted by an autho-
rized Hyundai dealer.
CHECKING PARKING
BRAKE PEDALG185A01TG-GAT
CAUTION:
If the parking brake pedal is not adjusted
properly, the vehicle may roll backwards
when parking on a steep hill.
!
G200A01A-AATReplacing a Fusible LinkA fusible link will melt if the electrical cir-
cuits from the battery are ever overloaded,
thus preventing damage to the entire wir-
ing harness. (This could be caused by a
short in the system drawing too much cur-
rent.) If this ever happens, have a Hyundai
dealer determine the cause, repair the
system and replace the fusible link. The
fusible links are located in a relay box in the
engine compartment for easy inspection.

CAUTION:
An open fuse indicates that there is a
problem in the electrical circuit. If you
replace a fuse and it blows as soon as the
accessory is turned on, the problem is
serious and should be referred to a
Hyundai dealer for diagnosis and repair.
Never replace a fuse with anything ex-
cept a fuse with the same or a lower
amperage rating. A higher capacity fuse
could cause damage and create a fire
hazard.NOTE:See page 6-33 for the fuse panel descrip-
tions.
G200C01CM-GATPower ConnectorNOTE:
o If the power connector is pulled up
from the fuse panel, the warning chime,
audio, clock and interior lamps, etc.,
will not operate. The following items
must be reset after replacement.
- Digital Clock
- Trip computer
- Automatic heating and cooling con-
trol system
- Audio
o Even though the power connector is
pulled up, the battery can still be dis-
charged by operation of the head-
lights or other electrical devices.
Your vehicle is equipped with a power
connector to prevent battery discharge if
your vehicle is parked without being oper-
ated for prolonged periods. Use the follow-
ing procedures before parking the vehicle
for prolonged periods.
1. Turn off the engine.
2. Turn off the headlights and tail lights.
3. Open the driver’s side panel cover and

If any electrolyte gets into your
eyes, flush your eyes with
clean water for at least 15 min-
utes and get immediate medi-
cal attention. If possible, con-
tinue to apply water with a
sponge or cloth until medical
attention is received.
If electrolyte gets on your skin,
thoroughly wash the contacted
area.
If you feel a pain or a burning
sensation, get medical atten-
tion immediately.
Wear eye protection when
charging or working near a bat-
tery.
Always provide ventilation
when working in an enclosed
space.WARNING:
!
WARNING:Always read the following in-
structions carefully when han-
dling a battery.
Keep lighted cigarettes and all
other flames or sparks away
from the battery.
Hydrogen, which is a highly
combustible gas, is always
present in battery cells and
may explode if ignited.
Keep batteries out of the reach
of children because batteries
contain highly corrosive SUL-
FURIC ACID. Do not allow bat-
tery acid to contact your skin,
eyes, clothing or paint finish.
o When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak, resulting in
personal injury. Lift with a battery
carrier or with your hands on opposite
corners.
o Never attempt to charge the battery
when the battery cables are con-
nected.
o The electrical ignition system works
with high voltage.
Never touch these components with
the engine running or the ignition
switched on.
