C130A01A-AATGOOD BRAKING PRACTICES
WARNING:
Nothing should be carried on top of the
cargo area cover behind the rear seat. If
there were an accident or a sudden stop,
such objects could move forward and cause
damage to the vehicle or injure the occu-
pants.
o After being parked, check to be sure the
parking brake is not engaged and that the
parking brake indicator light is out before
driving away.
o Driving through water may get the brakes
wet. They can also get wet when the car is
washed. Wet brakes can be dangerous!
Your car will not stop as quickly if the brakes
are wet. Wet brakes may cause the car to
pull to one side. To dry the brakes, apply the
brakes lightly until the braking action returns
to normal, taking care to keep the car under
control at all times. If the braking action does
not return to normal, stop as soon as it is safe
to do so and call your Hyundai dealer for
assistance.
o Don't coast down hills with the car out of gear.
This is extremely hazardous. Keep the car
in gear at all times, use the brakes to slow
down, then shift to a lower gear so that engine
braking will help you maintain a safe speed.o Don't "ride" the brake pedal. Resting your
foot on the brake pedal while driving can be
dangerous because it can result in the brakes
overheating and losing their effectiveness. It
also increases the wear of the brake com-
ponents.
o If a tire goes flat while you are driving, apply
the brakes gently and keep the car pointed
straight ahead while you slow down. When
you are moving slowly enough for it to be safe
to do so, pull off the road and stop in a safe
place.
o If your car is equipped with an automatic
transaxle, don't let your car creep forward.
To avoid creeping forward, keep your foot on
the brake pedal when the car is stopped.
o Use caution when parking on a hill. Engage
the parking brake and place the gear selec-
tor lever in "P" (automatic transaxle) or in first
or reverse gear (manual transaxle). If your
car is facing downhill, turn the front wheels
into the curb to help keep the car from rolling.
If your car is facing uphill, turn the front
wheels away from the curb to help keep the
car from rolling. If there is no curb or if it is
required by other conditions to keep the car
from rolling, block the wheels.
o Under some conditions your parking brake
can freeze in the engaged position. This is
most likely to happen when there is an ac-
cumulation of snow or ice around or near the
rear brakes or if the brakes are wet. If there
is a risk that the parking brake may freeze,
apply it only temporarily while you put the
gear selector lever in "P" (automatic) or in
C300D02L-GATIndicator and Warning
The indicator should illuminate when the ignition
key is turned to "ON" or "start", but should go
out after three seconds.
If the indicator does not illuminate, have it checked
by an authorized Hyundai dealer.
Should there be any unusual conditions in the
device, TCS illuminates as a warning.
If TCS illuminates, pull your car to a safe place
and stop the engine.
Then, start the engine again to check if the TCS
indicator goes out.
If the indicator remains lit even after the engine
has been started, have your car checked by an
authorized Hyundai dealer.
NOTE:1) When TCS illuminates, traction control
is automatically deactivated for safety.
2) This warning function is not provided
when the driver selects the TCS-OFF
mode.

7- 2 EMISSION CONTROL SYSTEMS
H010E01Y-AATEGR System (If installed)
This system helps reduce nitrogen oxides by
recirculating a part of the exhaust gas into the
engine, thereby reducing cylinder combustion
temperature, which results in lower output of
oxides of nitrogen.
H010D01A-AAT3. Exhaust Emission Control System
The Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle
performace.
H010B01A-AAT1. Crankcase Emission Control
System
The positive crankcase ventilation system is
employed to prevent air pollution caused by
blow-by gases being emitted from the crank-
case. This system supplies filtered air to the
crankcase through the air intake hose. Inside
the crankcase, the fresh air mixes with blow-by
gases, which then pass through the PCV valve
and into the induction system.
H010A01L-AATEMISSION CONTROL SYSTEM
Your Hyundai is equipped with an emission
control system to meet all requirements of the
U.S. Environmental Protection Agency or Cali-
fornia Air Resources Board.
There are three emission control systems which
are as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to assure the proper function of the
emission control systems, it is recommended
that you have your car inspected and main-
tained by an authorized Hyundai dealer in ac-
cordance with the maintenance schedule in this
manual.
Caution for Inspection and Maintenance
Test (2.7 V6 Vehicle with Traction Control
System)
o To prevent the vehicle from misfiring
during dynamometer testing, discon-
nect the ABS connector located on the
left side of the engine compartment.
o For more information, see shop manual
(BR-67, Wheel Speed Sensor)
H010C02S-AAT
2. Evaporative Emission Control
(Including ORVR: Onboard Refueling
Vapor Recovery) System
The Evaporative Emission Control System is
designed to prevent fuel vapors from escaping
into the atmosphere.
(The ORVR system is designed to allow the
vapors from the fuel tank to be loaded into a
canister while refueling at the gas station, pre-
venting the escape of fuel vapors into the
atmosphere.)
Canister
Fuel vapors generated inside the fuel tank are
absorbed and stored in the onboard canister.
When the engine is running, the fuel vapors
absorbed in the canister are drawn into the
surge tank through the purge control solenoid
valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is controlled
by the Engine Control Module (ECM); when the
engine coolant temperature is low during idling,
the PCSV closes so that evaporated fuel is not
taken into the engine. After the engine warms-
up during ordinary driving, the PCSV opens to
introduce evaporated fuel to the engine.

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 re-
placed when tread wear indicators appear. To
reduce the possibility of losing control, slow
down whenever there is rain, snow or ice on the
road.
I070A01A-AATTIRE BALANCING
A tire that is out of balance may affect handling
and tire wear. The tires on your Hyundai were
balanced before the car was delivered but may
need balancing again during the years you own
the car.
Whenever a tire is dismounted for repair, it
should be rebalanced before being reinstalled
on the car.
I090A01A-AATWHEN TO REPLACE TIRESWARNING:
Driving on worn-out tires is dangerous!
Worn-out tires can cause loss of braking
effectiveness, steering control and trac-
tion. When replacing tires, never mix radial
and bias ply tires on the same car. If you
replace radial tires with bias-ply tires, they
must be installed in sets of four.
The original tires on your car have tread wear
indicators. 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.
WARNING:o Using tires and wheels of other than the
recommended sizes could cause un-
usual handling characteristics that could
cause death, serious injury, or property
damage.
o Wheels that do not meet Hyundai's di-
mensional specifications may fit poorly
and result in damage to the vehicle,
including broken wheel studs.

Wear indicator
!
Tires should be rotated every 7,500 miles
(12,000 km). If you notice that tires are wearing
unevenly between rotations, have the car
checked by a Hyundai dealer so the cause may
be corrected.
After rotating, adjust the tire pressures and be
sure to check the wheel nut tightness.
WARNING:o Do not use the temporary spare tire for
tire rotation.
o Do not mix bias ply and radial ply tires
under any circumstances. This may
cause unusual handling characteristics
that could result in death, serious injury,
or property damage.

from highest to lowest, are AA, A, B, and C.
Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING:The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
Temperature A, B, C - The temperature grades
are A (the highest), B, and C, representing the
tire's resistance to the generation of heat and
its ability to dissipate heat when tested under
controlled conditions on a specified indoor labo-
ratory test wheel. Sustained high temperature
can cause the material of the tire to degenerate
and reduce tire life, and excessive temperature
can lead to sudden tire failure. The grade C
corresponds to a level of performance which all
passenger car tires must meet under the Fed-
eral Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel than
the minimum required by law.
WARNING:The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause
heat buildup and possible tire failure.
