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.

o Be sure you and your passengers always
wear seat belts and wear them properly.NOTE:o Both the driver's and front passenger's
pre-tensioner seat belts will be activated
in certain frontal collisions. The pre-
tensioner seat belts can be activated
alone or, where the frontal collision is
severe enough, together with the
airbags.
The pre-tensioners will not be activated
if the seat belts are not being worn at the
time of the collision.
o When the pre-tensioner seat belts are
activated, a loud noise may be heard and
fine dust, which may appear to be smoke,
may be visible in the passenger com-
partment. These are normal operating
conditions and are not hazardous.
o Although it is harmless, the fine dust
may cause skin irritation and should not
be breathed for prolonged periods. Wash
all exposed skin areas thoroughly after
an accident in which the pre-tensioner
seat belts were activated.
WARNING:
!
AIR
BAG
CAUTION:
o Because the sensor that activates the
SRS airbag is connected with the pre-
tensioner seat belt, the SRS airbag warn-
ing light on the instrument panel will
illuminate for approximately 6 seconds
after the ignition key has been turned to
the "ON" position, and then it should
turn off.
o If the pre-tensioner seat belt is not work-
ing properly, this warning light will illu-
minate even if there is no malfunction of
the SRS airbag. If the SRS airbag warning
light does not illuminate when the igni-
tion key is turned to "ON", or if it blinks
for a second and remains illuminated
after illuminating for approximately 6
seconds, or if it illuminates while the
vehicle is being driven, please have an
authorized Hyundai dealer inspect the
pre-tensioner seat belt or SRS airbag
system as soon as possible.
!
WARNING:
o Pre-tensioners are designed to operate
only one time. After activation, pre-
tensioner seat belts must be replaced.
All seat belts, of any type, should always
be replaced after they have been worn
during a collision.
o The pre-tensioner seat belt assembly
mechanisms become hot during activa-
tion. Do not touch the pre-tensioner seat
belt assemblies for several minutes after
they have been activated.
o Do not attempt to inspect or replace the
pre-tensioner seat belts yourself. This
must be done by an authorized Hyundai
dealer.
o Do not strike the pre-tensioner seat belt
assemblies.
o Do not attempt to service or repair the
pre-tensioner seat belt system in any
manner.
o Improper handling of the pre-tensioner
seat belt assemblies, and failure to heed
the warnings not to strike, modify, in-
spect, replace, service or repair the pre-
tensioner seat belt assemblies may lead
to improper operation or inadvertent
activation and serious injury.
o Always wear the seat belts when driving
or riding in a motor vehicle.

1FEATURES OF YOUR HYUNDAI48
o If the airbags inflate, they must be re-
placed by an authorized Hyundai dealer.
o Do not tamper with or disconnect SRS
wiring, or other components of the SRS
system. Doing so could result in injury,
due to accidental inflation of the airbags
or by rendering the SRS inoperative.
o If components of the airbag system must
be discarded, or if the vehicle must be
scrapped, certain safety precautions
must be observed. Your Hyundai dealer
knows these precautions and can give
you the necessary information. Failure
to follow these precautions and proce-
dures could increase the risk of personal
injury.
o If your car was flooded and has soaked
carpeting or water on flooring, you
shouldn't try to start the engine; have
the car towed to an authorized Hyundai
dealer.
!
WARNING:
B240C03NF-AATSRS CareThe SRS is virtually maintenance-free and so
there are no parts you can safely service by
yourself. If the SRS "AIRBAG" warning light
does not illuminate, or continuously remains on,
have your vehicle immediately inspected by
your Hyundai dealer.
Any work on the SRS system, such as remov-
ing, installing, repairing, or any work on the
steering wheel must be performed by a qualified
Hyundai technician. Improper handling of the
SRS system may result in serious personal
injury.
WARNING:
o Do not install a child restraint system in
the front passenger seat position.
A child restraint system must never be
placed in the front seat. The infant or
child could be severely injured by an
airbag deployment in case of an acci-
dent.
o Modification to SRS components or wir-
ing, including the addition of any kind of
badges to the pad covers or modifica-
tions to the body structure, can ad-
versely affect SRS performance and lead
to possible injury.
o For cleaning the airbag pad covers, use
only a soft, dry cloth or one which has
been moistened with plain water. Sol-
vents or cleaners could adversely affect
the airbag covers and proper deploy-
ment of the system.
o No objects should be placed over or near
the airbag modules on the steering wheel,
instrument panel, and the front
passenger's panel above the glove box,
because any such object could cause
harm if the vehicle is in a crash severe
enough to cause the airbags to inflate.

Door Ajar Warning Light and
Chime
The door ajar warning light warns you that a door
is not completely closed and the chime warns
you that the key is in the ignition switch.NOTE :The warning chime only sounds whenever
the key is in the ignition switch and the
driver's side front door is open simulta-
neously. The chime sounds until the key is
removed from the ignition switch or the
driver's side front door is closed.
B260M01A-AAT
Low Fuel Level Warning Light
The low fuel level warning light comes on when
the fuel tank is approaching empty. When it
comes on, you should add fuel as soon as
possible. Driving with the fuel level warning light
on or with the fuel level below "E" can cause the
engine to misfire and damage the catalytic
converter.B260N02A-AAT
Check Engine - Malfunction In-
dicator Light (MIL)
This light illuminates when there is a malfunction
of an exhaust gas related component, and the
system is not functioning properly so that the
exhaust gas regulation values are not satisfied.
This light will also illuminate when the ignition key
is turned to the "ON" position, and will go out in a
few seconds after the engine is started. If it
illuminates while driving, or does not illuminate
when the ignition key is turned to the "ON" position,
take your car to your nearest authorized Hyundai
dealer and have the system checked.
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.
B260J01NF-AAT
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, have the sys-
tem checked by your Hyundai dealer as soon
as possible.
B260K01S-AAT
Trunk Lid Open Warning Light
This light remains on unless the trunk lid is
completely closed and latched.

ABS Service Reminder
Indicator (SRI) (If Installed)
When the key is turned to the "ON" position, the
Anti-Lock Brake System indicator will come on
and then go off in a few seconds. If the ABS SRI
remains on, comes on while driving, or does not
come on when the key is turned to the "ON"
position, this indicates that there may be a
problem with the ABS.
If this occurs, have your vehicle checked by
your Hyundai dealer as soon as possible. The
normal braking system will still be operational,
but without the assistance of the anti-lock brake
system.
WARNING:
If both the ABS SRI and Parking Brake/
Brake fluid level warning lights remain "ON"
or come on while driving, there may be a
problem with E.B.D. (Electronic Brake Force
Distribution).
If this occurs, avoid sudden stops and have
your vehicle checked by your Hyundai dealer
as soon as possible.
B265C01NF-AAT
Electronic Stability Control
(ESC) Indicator Lights
(If Installed)
The electronic stability control indicators change
operation according to the ignition switch posi-
tion and whether the system is in operation or
not.
They will illuminate when the ignition key is
turned to the "ON" position, but should go out
after three seconds. If the ESC or ESC-OFF
indicator stays on, take your car to your autho-
rized Hyundai dealer and have the system
checked. See section 2 for more information
about the ESC.B260Q02NF-GAT
CRUISE Indicator Light
The cruise indicator light in the instrument clus-
ter is illuminated when the cruise control ON/
OFF button on the steering wheel is pulled.
The indicator light turns off when the cruise
control ON/OFF button is pushed again. Infor-
mation about the use of cruise control begins on
page 1-93.
B260R01NF-GAT
Cruise SET Indicator Light
The Cruise SET indicator light in the instrument
cluster is illuminated when the cruise control
"COAST/SET" or "RES/ACCEL" switch is
pushed. The Cruise SET indicator light does not
illuminate when the cruise control "CANCEL"
switch is pushed or the system is disengaged.
To disengage the cruise control system, refer
to "To cancel the cruise speed" on page 1-94.B260S01NF-GAT
Low Windshield Washer Fluid
Level Warning Light
The low windshield washer fluid warning light
comes on when the washer fluid reservoir is
approaching empty. When it comes on, add
washer fluid at your earliest opportunity.B270A01O-AATBRAKE PAD WEAR WARNING SOUNDThe front and rear disc brake pads have wear
indicators that should make a high-pitched
squealing or scraping noise when new pads are
needed. The sound may come and go or be
heard all the time when the vehicle is moving. It
may also be heard when the brake pedal is
pushed down firmly. Excessive rotor damage
will result if the worn pads are not replaced. See
your Hyundai dealer immediately.

DRIVING YOUR HYUNDAI
16
o Remember, your Hyundai does not require
extended warm-up. After the engine has
started, allow the engine to run for 10 to 20
seconds prior to placing the vehicle in gear.
In very cold weather, however, give your
engine a slightly longer warm-up period.
o Don't "lug" or "over-rev" the engine. Lugging
is driving too slowly in too high a gear result-
ing in the engine bucking. If this happens,
shift to a lower gear. Over-revving is racing
the engine beyond its safe limit. This can be
avoided by shifting at the recommended
speeds.
o Use your air conditioning sparingly. The air
conditioning system is operated by engine
power so your fuel economy is reduced
when you use it. o Be sure that the wheels are aligned cor-
rectly. Improper alignment can result from
hitting curbs or driving too fast over irregular
surfaces. Poor alignment causes faster tire
wear and may also result in other problems
as well as greater fuel consumption.
o Keep your car in good condition. For better
fuel economy and reduced maintenance
costs, maintain your car in accordance with
the maintenance schedule in Section 5. If
you drive your car in severe conditions,
more frequent maintenance is required (see
Section 5 for details).
o Keep your car clean. For maximum service,
your Hyundai should be kept clean and free
of corrosive materials. It is especially impor-
tant that mud, dirt, ice, etc. not be allowed to
accumulate on the underside of the car. This
extra weight can result in increased fuel
consumption and also contribute to corro-
sion.
o Travel lightly. Don't carry unnecessary
weight in your car. Weight reduces fuel
economy.
o Don't let the engine idle longer than neces-
sary. If you are waiting (and not in traffic),
turn off your engine and restart only when
you're ready to go.
DRIVING FOR ECONOMYC140A02A-AATYou can save fuel and get more miles from your
car if you follow these suggestions:
o Drive smoothly. Accelerate at a moderate
rate. Don't make "jack-rabbit" starts or full-
throttle shifts and maintain a steady cruising
speed. Don't race between stoplights. Try to
adjust your speed to that of the other traffic
so you don't have to change speeds unnec-
essarily. Avoid heavy traffic whenever pos-
sible. Always maintain a safe distance from
other vehicles so you can avoid unneces-
sary braking. This also reduces brake wear.
o Drive at a moderate speed. The faster you
drive, the more fuel your car uses. Driving at
a moderate speed, especially on the high-
way, is one of the most effective ways to
reduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This
can increase fuel consumption and also
increase wear on these components. In
addition, driving with your foot resting on the
brake pedal may cause the brakes to over-
heat, which reduces their effectiveness and
may lead to more serious consequences.
o Take care of your tires. Keep them inflated
to the recommended pressure. Incorrect
inflation, either too much or too little, results
in unnecessary tire wear. Check the tire
pressures at least once a month.

SMOOTH CORNERINGC150A01A-AATAvoid braking or gear changing in corners,
especially when roads are wet. Ideally, corners
should always be taken under gentle accelera-
tion. If you follow these suggestions, tire wear
will be held to a minimum.
C160A01A-AATThe more severe weather conditions of winter
result in greater wear and other problems. To
minimize the problems of winter driving, you
should follow these suggestions:C160B01A-AATSnowy or Icy ConditionsTo drive your vehicle in deep snow, it may be
necessary to use snow tires or to install tire
chains on your tires. If snow tires are needed,
it is necessary to select tires equivalent in size
and type of the original equipment tires. Failure
to do so may adversely affect the safety and
handling of your car. Furthermore, speeding,
rapid acceleration, sudden brake applications,
and sharp turns are potentially very hazardous
practices.
During deceleration, use engine braking to the
fullest extent. Sudden brake applications on
snowy or icy roads may cause skids to occur.
You need to keep sufficient distance between
the vehicle in operation in front and your vehicle.
Also, apply the brake gently. It should be noted
that installing tire chains on the tire will provide
a greater driving force, but will not prevent side
skids.NOTE:Tire chains are not legal in all states. Check
state laws before fitting tire chains.WINTER DRIVING
C160D01A-AATCheck Battery and CablesWinter puts additional burdens on the battery
system. Visually inspect the battery and cables
as described in Section 6. The level of charge
in your battery can be checked by your Hyundai
dealer or a service station.C160C01A-AATUse High Quality Ethylene Glycol
CoolantYour Hyundai is delivered with high quality
ethylene glycol coolant in the cooling system. It
is the only type of coolant that should be used
because it helps prevent corrosion in the cool-
ing system, lubricates the water pump and
prevents freezing. Be sure to replace or replen-
ish your coolant in accordance with the main-
tenance schedule in Section 5. Before winter,
have your coolant tested to assure that its
freezing point is sufficient for the temperatures
anticipated during the winter.
