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.
B260N01A-AAT
Malfunction Indicator Light
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. 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.
B260P02Y-GATABS Service Reminder
Indicator (If installed)
When the key is turned to the "ON" position, the
Anti-Lock Brake System 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.
CAUTION:If both 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.

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.C070E02A-AATRecommended Shift Points

C070B01A-AATUsing the Clutch
The clutch should be pressed all the way to the
floor before shifting, then released slowly. The
clutch pedal should always be used after fully
returning to the original position. Do not rest your
foot on the clutch pedal while driving. This can
cause unnecessary wear.
Do not partially engage the clutch to hold the car
on an incline. This causes unnecessary wear.
Use the parking brake to hold the car on an
incline. Do not operate the clutch pedal rapidly
and repeatedly.
C070D02A-AATGood Driving Practices
o 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
WARNING:o Avoid high cornering speeds.
o Do not make quick steering wheel move-
ments, such as sharp lane changes or
fast, sharp turns.
o Always wear your seat belts.
In a collision crash, un unbelted person
is significantly more likely to die than a
person wearing a seatbelt.
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.

C120A02A-AATANTI-LOCK BRAKE SYSTEM
(If installed)
The Anti-Lock Brake System (ABS) is designed
to prevent wheel lock-up during sudden braking
or on hazardous road surfaces. The ABS con-
trol module monitors the wheel speed and con-
trols the pressure applied to each brake. Thus,
in emergency situations or on slick roads, ABS
will increase vehicle control during braking.
NOTE:During ABS operation, a slight pulsation
may be felt in the brake pedal when the
brakes are applied. Also, a noise may be
heard in the engine compartment while
braking. These conditions are normal and
indicate that the anti-lock brake system is
functioning properly.
C090N01O-AATGood Driving Practices
o 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 ve-
hicle speed can cause the drive wheels to
lose traction and the vehicle to go out of
control.
WARNING:ABS will not prevent accidents due to im-
proper 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 may be
longer than for those without it in the
following road conditions.
WARNING:o Avoid high cornering speeds.
o Do not make quick steering wheel move-
ments, such as sharp lane changes or
fast, sharp turns.
o Always wear your seat belts.
In a collision crash, un unbelted person
is significantly more likely to die than a
person wearing a seatbelt.
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.

DRIVING YOUR HYUNDAI 2- 11
!
o Driving on rough, gravel or snow-cov-
ered roads.
o Driving with tire chains installed.
o Driving on roads where the road surface
is pitted or has different surface height.
During these conditions the vehicle should
be driven at reduced speeds. The safety
features of an ABS equipped vehicle should
not be tested by high speed driving or
cornering. This could endanger the safety
of yourself or others.
C300A03Y-GAT
TRACTION CONTROL SYSTEM (TCS)
(If installed)
!
C300B01E-GATTCS ON/OFF Mode
In the TCS ON mode, the indicator in the
instrument cluster will not be illuminated.
To switch the TCS OFF mode, press the TCS
switch . And the SLIP control will be deactivated
and the TCS indicator in the instrument cluster
will be illuminated.
NOTE:1) Turn off the engine. Then restart the
engine, and the TCS mode will automati-
cally turn "ON".
2) When the traction control is operating
properly, you can feel a slight pulsation
in the vehicle. This is only the effect of
brake control and indicates nothing
unusual.
3) When the engine starts, a click is heard
from the engine compartment; however,
this is only the sound of traction control
being checked.
4) When moving out of the mud or fresh
snow, pressing the accelerator pedal
may not cause the engine speed to in-
crease. On slippery road surfaces, the traction control
system (TCS) limits the drive wheels from
spinning excessively, thus helping the car to
accelerate. It also provides sufficient driving
force and steering performance as the car turns
at accelerated speeds. TCS has - SLIP control.
SLIP Control
Limits the drive wheels from spinning exces-
sively during starting or while making acceler-
ated turns on slippery roads to avoid losing the
driving force of the front wheels.
Driving hints
TCS does not actively apply brakes. Be sure to
decelerate the car sufficiently before entering
curves.
CAUTION:When the TCS indicator blinks, SLIP control
has been activated. It also means that the
road is slippery or your car is accelerating
excessively. In this situation, release foot
pressure from the accelerator pedal and
maintain moderate speed.
WARNING:Traction control is only a driving aid; all
normal precautions for driving in inclement
weather and on slippery road surfaces
should be observed.

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.
