Driving HintsTCS does not actively apply brakes. Be sure to
decelerate the car sufficiently before entering
curves.
CAUTION:
When the TCS indicator blinks, SLIP con-
trol function has been activated. It also
means that the road is slippery or your car
is accelerating excessively. In this situa-
tion, gently release foot pressure from the
accelerator pedal and maintain moderate
speed.
!
WARNING:
Traction control is a driving aid; all normal
precautions for driving in inclement weath-
er and on slippery driving surfaces should
be observed.
C310B02O-AATTCS ON/OFF ModeWhen the TCS is operating, the TCS indicator
in the instrument cluster will blink.
If you turn the system off by pressing the TCS
switch, the TCS-OFF indicator will come on and
stay on. In the TCS-OFF mode, the SLIP control
will be deactivated. Adjust you driving accord-
ingly. To turn the system back on, press the
switch again. The TCS-OFF indicator should go
off.NOTE:1) The TCS mode will automatically be
turned ON after the engine is turned off
and restarted.
2) When the traction control system is op-
erating 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 may be
heard from the engine compartment;
this is the sound of the 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 due to TCS operation.
C310D01JM-AATIndicators and WarningThe indicators should illuminate when the igni-
tion key is turned to ON or START but should
go out after approximately three seconds.
If the indicators do not illuminate, or the TCS or
TCS-OFF indicator does not go out after 3
seconds, have the system checked by an
authorized dealer.
Should there be any unusual conditions in the
TCS System while driving, TCS-OFF indicator
illuminates as a warning.
If TCS-OFF indicator illuminates, pull your car
to a safe place and stop the engine.
Then, start the engine again to check if the TCS-
OFF 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:When the TCS-OFF indicator illuminates,
traction control is automatically deacti-
vated.

ELECTRONIC STABILITY
CONTROL (ESC) SYSTEMC310A03JM-AAT(If installed)
C310A01JM-U
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.
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.
C310B01JM-AATESC ON/OFF ModeWhen the ESC is operating, the ESC indicator
in the instrument cluster will blink.
If you turn the system off by pressing the ESC
switch, the ESC-OFF indicator will come on and
stay on. In the ESC-OFF mode, the stability
control will be deactivated. Adjust your driving
accordingly. To turn the system back on, press
the switch again. The ESC-OFF indicator should
go off.NOTE:The ESC mode will automatically be turned
ON after the engine is turned off and re-
started.

CAUTION:
o While the full-time 4WD vehicle is being
raised on a jack, never start the engine or
cause the tires to rotate.
There is danger that rotating tires touch-
ing the ground could cause the vehicle
to go off the jack and to jump forward.
o If one of the front or rear wheels begins
to spin in mud, snow, etc., the vehicle
can sometimes be driven out by de-
pressing the accelerator pedal further;
however, avoid running the engine con-
tinuously at high rpm because doing so
could damage the 4WD system. (10)When using tire chains, always attach them
to the front wheels.
(11)If the front or rear wheels get stuck in the
mud, do not spin them recklessly. The 4WD
system could be damaged.
o In rare cases when it's unavoidable that
a 4WD vehicle is to be inspected on a
2WD roll tester, strictly follow the proce-
dures.
1. Check the tire pressures recom-
mended for your vehicle.
2. Place the front wheels on the roll
tester as shown in the illustration.
3. Release the parking brake.
4. Place the rear wheels on the tempo-
rary free roller as shown in the illustra-
tion.
!!
WARNING:
Keep away from the front of the vehicle
while inspecting. This is very dangerous as
the vehicle can jump forward and cause
serious injury or death.
!
WARNING:
o Avoid high cornering speeds.
o Do not make quick steering wheel move-
ments, such as sharp lane charges or
fast, sharp turns.
o The risk of rollover is greatly increased if
you lose control of your vehicle at high-
way speeds.
o In a collision, an unbelted person is
signicantly more likely to be seriously
injured or killed than a person wearing a
seat belt.
o Loss of control may 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. (9) For a speedometer test or inspection/main-
tenance (I/M) program of a Tucson 4WD
vehicle, use a four wheel chassis dynamom-
eter.
CAUTION:
Never engage the parking brake while per-
forming these tests.

WARNING:
The cooling fan is controlled by engine
coolant temperature and may sometimes
operate even when the engine is not run-
ning. Use extreme caution when working
near the blades of the coolant fan so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases, the fan will automatically shut off.
This is a normal condition. 2. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This
relieves any pressure remaining in the cool-
ing system. And remove the radiator cap by
pushing down and turning counterclock-
wise.
3. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow all
the engine coolant to drain from the cooling
system, then securely close the drain cock.
4. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer's directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
5. Fill the radiator with clean demineralized or
distilled water. Continue to add clean dem-
ineralized or distilled water in small quantities
until the fluid level stays up in the radiator
neck.6. Start the engine, top off the radiator with
water and then add coolant to the reservoir
until the level is between "L" and "F".
7. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.
G050D02A-AATTo Change the Engine CoolantThe engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
HJM5034G050D01JM
CAUTION:
Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park-
ing brake and remove the radiator cap when
cool.

G140D02A-AATChecking the Compressor Drive Belt
!
G140C01A-AATLubricationTo lubricate the compressor and the seals in the
system, the air conditioning should be run for at
least 10 minutes each week. This is particularly
important during cool weather when the air
conditioning system is not otherwise in use.G140B01A-AATChecking the Air Conditioning Opera-
tion1. Start the engine and let it run at a fast idle for
several minutes with the air conditioning set
at the maximum cold setting.
2. If the air coming out of the in-dash vents is
not cold, have the air conditioning system
inspected by your Hyundai dealer.
CAUTION:
Running the air conditioning system for
extended periods of time with a low refrig-
erant level may damage the compressor.
When the air conditioning is being used regu-
larly, the compressor drive belt tension should
be checked at least once a month with the
engine turned off.
To check the drive belt tension, press down on
the belt halfway between the engine crankshaft
and compressor pulleys. Pressing with your
finger, you should not be able to deflect this belt
anymore than 1/3 of an inch. If the belt is too
loose, have it adjusted by your Hyundai dealer.
CHANGING THE CLIMATE CON-
TROL AIR FILTERB145A03JM-GAT(For Evaporator and Blower Unit)
(If Installed)The climate control air filter is located in front of
the evaporator unit behind the glove box.
It helps to decrease the amount of pollutants
entering the car.
1. Open the glove box and remove the support
strap through the hole.

POWER STEERING FLUID LEVELG230A03A-AAT
G220C01A-AAT
Checking Condenser Cooling FanThe condenser cooling fan should come on
automatically whenever the air conditioning is in
operation.
The power steering fluid level should be checked
regularly. To check the power steering fluid
level, be sure the engine is "OFF", then check
to make certain that the power steering fluid
level is between the "MAX" and "MIN" level
markings on the fluid reservoir.
NOTE:Grinding noise from the power steering
pump may be heard immediately after the
engine is started in extremely cold condi-
tions (below - 4°F). If the noise stops during
warm up, there is no abnormal function in
the system. It is due to a power steering
fluid characteristic in extremely cold condi-
tions.
G220B01A-AATChecking Engine Cooling FanThe engine cooling fan should come on auto-
matically if the engine coolant temperature is
high.

EMISSION CONTROL SYSTEMS2
EMISSION CONTROL SYSTEM
H010D01A-AAT3. Exhaust Emission Control SystemThe Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle
performace.
H010B01A-AAT1. Crankcase Emission Control
SystemThe 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.
H010A02O-AATYour 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 the Inspection and Maintenance
Test (V6 Vehicle with Traction Control Sys-
tem)
o To prevent the vehicle from misfiring
during dynamometer testing, discon-
nect the ABS connector in the engine
compartment. (2.7 V6 only)
o For more information, see shop manual
(Wheel Speed Sensor).
o After dynamometer testing is completed,
erase the ABS/TCS DTC (Diagnotic
Trouble Code) with a GST (Generic Scan
Tool) or Hi-Scan Pro.
CanisterFuel vapors generated inside the fuel tank are
absorbed and stored in the canister. When the
engine is running, the fuel vapors absorbed in
the canister are drawn into the induction system
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.
H010C01S-AAT2. Evaporative Emission Control (Includ-
ing ORVR: Onboard Refueling Vapor
Recovery) SystemThe 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.)
