VEHICLE DATA COLLECTION AND EVENT DATA RECORDERS
Your Hyundai vehicle is equipped with many high technology, electronically controlled systems that
help to ensure your vehicle operates properly and provides the performance that you expect. These
systems utilize computers to monitor the operation of various systems and components and help to
control their operation. These computerized system operations are wide-ranging and involve
components to reduce emissions, to continuously evaluate the readiness of the airbag and seat belt
pretensioner systems, to determine when the airbag and seat belt pre-tensioner systems should be
deployed and then to activate the deployment, and if equipped, to operate anti-lock braking, traction
control and electrical stability control to assist the driver to control the vehicle in difficult driving
situations. These systems electronically store information that is useful to service technicians when
they need to diagnose and repair these systems. Additional information is stored only when a crash
occurs that results in the deployment of the airbags or seat belt pre-tensioners. This type of data storage
is done by devices called event data recorders(EDR).
After a crash event, the airbag and seat belt pre-tensioner computer system, known as the Supplemental
Restraint System Control Module (SRSCM) or Airbag Control Unit (ACU), may record some information
about the condition of the vehicle and how it was being operated. This information consists of data
related to seat belt usage and if there was diagnostic information in the airbag or seat belt systems
at the time that a crash occurred, and if the ACU sensed that a crash of sufficient severity occurred to
require seat belt pre-tensioner or airbag deployment.
To retrieve this information, special equipment is needed and access to the vehicle or the device that
stores the data is required. Hyundai will not access information about a crash event or share it with
others except:
o in response to an official request of police or similar government office, or
o with the consent of the vehicle owner or, if the vehicle is leased, with the consent of the lessee, or
o as part of Hyundai’s defense of litigation, or
o as required by law.

Parking Brake/Low Brake Fluid
Level Warning Light
The brake fluid level warning light indicates that
the brake fluid level in the brake master cylinder
is low and hydraulic brake fluid conforming to
DOT 3 or DOT 4 specifications should be
added. After adding fluid, if no other trouble is
found, the car should be immediately and care-
fully 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.
Your Hyundai is equipped with dual-diagonal
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 sys-
tem or brake hydraulic system is danger-
ous, and could result in a serious injury or
death.Warning Light OperationThe parking brake/brake fluid level warning 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 re-
leased.
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.

Charging System Warning Light
The charging system warning light should come
on when the ignition is turned on, then go out
when the engine is running. If the light stays on
while the engine is running, there is a malfunc-
tion in the electrical charging system. If the light
comes on while you are driving, stop, turn off the
engine and check under the hood. First, make
certain the generator drive belt is in place. If it is,
check the tension of the belt. Do this as shown
on page 6-20 by pushing down on the center of
the belt. Have the system checked by your
Hyundai dealer as soon as possible.B260B01JM-AAT
Tail Gate Open Warning Light
This light remains on unless the tail gate and/or
tail gate window is completely closed and latched.

CAUTION:
o Use when the engine is running and
remove a plug from the power outlet
after using the electric appliance. Using
when the engine stops or remaining the
electric appliance with plugged in for
many hours may cause the battery to be
discharged.
o Do not use the power outlet to connect
electric accessories or equipment other
than those designed to operate on 12
volts.
o Some electronic devices can cause elec-
tronic interference when plugged into
the power outlet. These devices may
cause excessive audio noise and mal-
functions in other electronic systems or
devices used in your vehicle.

console .
WARNING:
o Use caution when using the drink hold-
ers. A spilled beverage that is very hot
can injure you or your passengers. Spilled
liquids can damage interior trim and
electrical components.
o Do not place objects other than cups or
cans in the drink holder. The objects can
be thrown out in the event of a sudden
stop or an accident, possibly injuring
the passengers in the vehicle.

FUSES

G200B02JM-AATReplacing Accessory Fuses
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 fuse box for the lights and other electrical
accessories will be found on the left side of
crash pad. Inside the box you will find a list
showing the circuits protected by each fuse.
If any of your car's lights or other electrical
accessories stop working, a blown (open) fuse
could be the reason. If the fuse has opened, you
will see that the metal strip inside the fuse has
melted through. If you suspect a blown fuse,
follow this procedure:
G200A03A-AATReplacing a Fusible LinkA fusible link will melt if the electrical circuits from
the battery are ever overloaded, thus prevent-
ing damage to the entire wiring harness. (This
could be caused by a short in the system
drawing too much current.) 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 compartement for easy inspection.

CATALYTIC CONVERTER
!
WARNING:
o Use unleaded fuel only.
o Maintain the engine in good operating
condition. Extremely high catalytic con-
verter temperatures can result from im-
proper operation of the electrical, igni-
tion or multiport electronic fuel injec-
tion.
o If your engine stalls, pings, knocks, or is
hard to start, have your Hyundai dealer
inspect and repair the problem as soon
as possible.
o Avoid driving with a very low fuel level.
Running out of gasoline may cause the
engine to misfire and result in damage to
the catalytic converter.
o Avoid idling the engine for periods
longer than 10 minutes.
o The vehicle should not be pushed or
pulled to get started. This may cause the
catalytic converter to overheat and cre-
ate a fire hazard.
o Do not touch the catalytic converter or
any other part of the exhaust system
while the catalytic converter is hot. Shut
off the engine, wait for at least one hour
before touching the catalytic converter
or any other part of the exhaust system.
H020A01A-AATAll Hyundai vehicles are equipped with a mono-
lith type three-way catalytic converter to re-
duce the carbon monoxide, hydrocarbons and
nitrogen oxides contained in the exhaust gas.
Exhaust gases passing through the catalytic
converter cause it to operate at a very high
temperature. The introduction of large amounts
of unburned gasoline into the exhaust may
cause the catalytic converter to overheat and
create a fire hazard. This risk may be reduced
by observing the following:

Catalytic Converter
!
WARNING:
o Remember that your Hyundai dealer is
your best source of assistance.
o Do not stop your Hyundai over any com-
bustible material such as grass, paper,
leaves or rags. These materials might
contact the hot catalytic converter and a
fire might result.
