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.

C070B02A-AATUsing the ClutchThe clutch should be pressed all the way to the
floor before shifting, then released slowly. The
clutch pedal should always be fully released
while driving. Do not rest your foot on the clutch
pedal while driving. This can cause unneces-
sary wear. Do not partially engage the clutch to
hold the car on an incline. This causes unnec-
essary wear. Use the foot brake or parking
brake to hold the car on an incline. Do not
operate the clutch pedal rapidly and repeatedly.
WARNING:
o Always buckle-up! In a collision, an
unbelted occupant is significantly more
likely to be seriously injured or killed
than a properly belted occupant.
o Avoid high speeds when cornering or
turning.
o Do not make quick steering wheel move-
ments, such as sharp lane changes or
fast, sharp turns.
o The risk of rollover is greatly increased if
you lose control of your vehicle at high-
way speeds.
o Loss of control often occurs if two or
more wheels drop off the roadway and
the driver oversteers to reenter the road-
way.
o In the event your vehicle leaves the road-
way, do not steer sharply. Instead, slow
down before pulling back into the travel
lanes.
o Never exceed posted speed limits.
C070D03O-AATGood Driving Practiceso Never take the car out of gear and coast
down a hill. This is extremely hazardous.
Always leave the car in gear.
o Don't "ride" the brakes. This can cause them
to overheat and malfunction. Instead, when
you are driving down a long hill, slow down
and shift to a lower gear. When you do this,
engine braking will help slow the car.
o Slow down before shifting to a lower gear.
This will help avoid over-revving the engine,
which can cause damage.
o Slow down when you encounter cross winds.
This gives you much better control of your
car.
o Be sure the car is completely stopped before
you attempt to shift into reverse. The
transaxle can be damaged if you do not. To
shift into reverse, depress the clutch, move
the shift lever to neutral, wait three seconds,
then shift to the reverse position.
o Exercise extreme caution when driving on a
slippery surface. Be especially careful when
braking, accelerating or shifting gears. On a
slippery surface, an abrupt change in ve-
hicle speed can cause the drive wheels to
lose traction and the vehicle to go out of
control.

C090N05O-AATGood Driving Practiceso Never move the gear selector lever from "P"
or "N" to any other position with the accelera-
tor pedal depressed.
o Never move the gear selector lever into "P"
when the vehicle is in motion.
o Be sure the car is completely stopped before
you attempt to shift into "R".
o Never take the car out of gear and coast
down a hill. This may be extremely hazard-
ous. Always leave the car in gear when
moving.
o Do not "ride" the brakes. This can cause
them to overheat and malfunction. Instead,
when you are driving down a long hill, slow
down and shift to a lower gear. When you do
this, engine braking will help slow the car.
o Slow down before shifting to a lower gear.
Otherwise, the lower gear may not be en-
gaged.
o Always use the parking brake. Do not de-
pend on placing the transaxle in "P" to keep
the car from moving.
o Exercise extreme caution when driving on a
slippery surface. Be especially careful when
braking, accelerating or shifting gears. On a
slippery surface, an abrupt change in vehicle
speed can cause the drive wheels to lose
traction and the vehicle to go out of control.
o Optimum vehicle performance and economy
is obtained by smoothly depressing and
releasing the accelerator pedal.
WARNING:
o Always buckle-up! In a collision, an
unbelted occupant is significantly more
likely to be seriously injured or killed
than a properly belted occupant.
o Avoid high speeds when cornering or
turning.
o Do not make quick steering wheel move-
ments, such as sharp lane changes or
fast, sharp turns.
o The risk of rollover is greatly increased if
you lose control of your vehicle at high-
way speeds.
o Loss of control often occurs if two or
more wheels drop off the roadway and
the driver oversteers to reenter the road-
way.
o In the event your vehicle leaves the road-
way, do not steer sharply. Instead, slow
down before pulling back into the travel
lanes.
o Never exceed posted speed limits.
WARNING:
If your vehicle becomes stuck in snow,
mud, sand, etc., then you may attempt to
rock the vehicle free by moving it forward
and backward. Do not attempt this proce-
dure if people or objects are anywhere near
the vehicle. During the rocking operation
the vehicle may suddenly move forward or
backward as it becomes unstuck, causing
injury or damage to nearby people or ob-
jects.

WARNING:
ABS (ESC) will not prevent accidents due to
improper or dangerous driving maneuvers.
Even though vehicle control is improved
during emergency braking, always main-
tain a safe distance between you and ob-
jects ahead. Vehicle speeds should always
be reduced during extreme road condi-
tions.
The braking distance for cars equipped
with an anti-lock braking system (Elec-
tronic Stability Control System) may be
longer than for those without it in the
following road conditions.
During these conditions the vehicle should
be driven at reduced speeds:
o Rough, gravel or snow-covered roads.
o With tire chains installed.
o On roads where the road surface is pit-
ted or has different surface height.
The safety features of an ABS (ESC)
equipped vehicle should not be tested by
high speed driving or cornering. This could
endanger the safety of yourself or others.
ELECTRONIC STABILITY CONTROL
(ESC) SYSTEMC310A02NF-AAT
The Electronic Stability Control (ESC) system
is designed to stabilize the vehicle during cor-
nering manuevers. ESC checks where you are
steering and where the vehicle is actually going.
ESC applies the brakes at individual wheels and
intervenes in the engine management system
to stabilize the vehicle.
The Electronic Stability Control (ESC) system
is an electronic system designed to help the
driver maintain vehicle control under adverse
conditions. It is not a substitute for safe driving
practices. Factors including speed, road con-
ditions and driver steering input can all affect
whether ESC will be effective in preventing a
loss of control. It is still your responsibility to
drive and corner at reasonable speeds and to
leave a sufficient margin of safety.
B310A01NF-A
WARNING:
Never drive too fast for the road conditions
or too quickly when cornering. Electronic
stability control (ESC) will not prevent ac-
cidents. Excessive speed in turns, abrupt
maneuvers and hydroplaning on wet sur-
faces can still result in serious accidents.
Only a safe and attentive driver can prevent
accidents by avoiding maneuvers that
cause the vehicle to lose traction. Even with
ESC installed, always follow all the normal
precautions for driving - including driving
at safe speeds for the conditions.

C160K01A-AATCarry Emergency EquipmentDepending on the severity of the weather where
you drive your car, you should carry appropri-
ate emergency equipment. Some of the items
you may want to carry include tire chains, tow
straps or chains, flashlight, emergency flares,
sand, a shovel, jumper cables, a window scraper,
gloves, ground cloth, coveralls, a blanket, etc.
HIGHER SPEED MOTORINGC170A02A-AATPre-Trip Inspections1. Tires:
Adjust the tire inflation pressures to specifica-
tion. Low tire inflation pressures will result in
overheating and possible failure of the tires.
Avoid using worn or damaged tires which may
result in reduced traction or tire failure.NOTE:Never exceed the maximum tire inflation
pressure shown on the tires.2. Fuel, engine coolant and engine oil:
High speed travel consumes more fuel than
urban motoring. Do not forget to check both
engine coolant and engine oil.
3. Drive belt:
A loose or damaged drive belt may result in
overheating of the engine.
WARNING:
o Underinflated or overinflated tires can
cause poor handling, loss of vehicle
control, and sudden tire failure leading
to accidents, injuries, and even death.
Always check tires are properly inflated
before driving. Refer to pages 2-23 and
8-3 for proper tire pressures and further
information.
o Driving on tires with no or insufficient
tread is dangerous. Worn-out tires can
result in loss of vehicle control, colli-
sions, injury, and even death. Worn-out
tires should be replaced as soon as
possible and should never be used for
driving. Always check tire tread before
driving your car. Refer to 8-10 for further
information and tread limits.

WARNING:
To reduce the chance or serious or
fatal injuries from an accident caused
by tire failure or loss of vehicle con-
trol:
o Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of brak-
ing effectiveness, steering con-
trol, and traction.
o Do not drive your vehicle with too
little or too much pressure in your
tires. This can lead to uneven
wear and tire failure.
o When replacing tires, never mix
radial and bias-ply tires on the
same car. You must replace all
tires (including the spare) if mov-
ing from radial to bias-ply tires.
HNF5015 I090A04JM-AAT
WHEN TO REPLACE TIRES
The original tires on your car have tread
wear indicators. The location of tread
wear indicators is shown by the "TWI"
or " " marks, etc. The tread wear
indicators appear when the tread depth
is 0.06 in. (1.6 mm). The tire should be
replaced when these appear as a solid
bar across two or more grooves of the
tread. Always replace your tires with
those of the recommended size. If you
change wheels, the new wheel's rim
width and offset must meet Hyundai
specification.

I080A01A-AATTIRE TRACTION
Tire traction can be reduced if you drive
on worn tires, tires that are improperly
inflated or on slippery road surfaces.
Tires should be replaced when tread
wear indicators appear. To reduce the
possibility of losing control, slow down
whenever there is rain, snow or ice on
the road.

Traction AA, A, B, C - The traction
grades, from highest to lowest, are AA,
A, B, and C. Those grades represent
the tire's ability to stop on wet pave-
ment as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction per-
formance.
!
WARNING:
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not in-
clude acceleration, cornering, hy-
droplaning, or peak traction charac-
teristics.
CONSUMER INFORMATIONI130A01A-AATThis consumer information has been prepared
in accordance with regulations issued by the
National Highway Traffic Safety Administration
of the U.S. Department of Transportation. It
provides the purchasers and/or prospective
purchasers of Hyundai automobiles with infor-
mation on uniform tire quality grading. Your

you may have as you read this information.
I130B04A-AATTire Quality Grading
Department of Transportation quality
grades - All passenger vehicle tires
must conform to Federal Safety Stan-
dards in addition to these grades. These
quality grades are molded on the
sidewall.
Treadwear - The treadwear grade is a
comparative rating based on the wear
rate of the tire when tested under con-
trolled conditions on a specified gov-
ernment test course. For example, a
tire graded 150 would wear one and a
half (1 - 1/2) times as well on the
government course as a tire graded
100. The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to varia-
tions in driving habits, service prac-
tices and differences in road character-
istics and climate.
