FUEL FILTER (FOR DIESEL)
Draining water from the fuel filter
The fuel filter for diesel engine plays an
important role of separating water from
fuel and accumulating the water in itsbottom.
If water accumulates in the fuel filter, the
warning light comes on when the ignition
switch is in the ON position. If this warning light illuminates,
take your car to an authorized
HYUNDAI dealer and have
the water drained and
checked. Extracting air from the fuel filter
If you drove until you have no fuel left or
if you replaced the fuel filter, be sure to
extract air in the fuel system as it makes
you difficult to start the engine.
1. Remove the air extract nozzle cap on
the fuel filter.
2. Pump up and down until the fuel flows out of the plug opening.

CAUTION
 Underinflation also results in
excessive wear, poor handlingand reduced fuel economy. Wheel deformation also ispossible. Keep your tire pres-sures at the proper levels. If a tire frequently needs refilling,have it checked by an author-ized HYUNDAI dealer.
 Overinflation produces a harsh ride, excessive wear atthe center of the tire tread, anda greater possibility of dam-age from road hazards.
TIRES AND WHEELS
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle. Recommended cold tire inflation pressures All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure,
refer to “Tire and wheels” in section8. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING -
Tire underin- flation
Severe underinflation (70 kPa(10 psi) or more) can lead to
severe heat build-up, causing
blowouts, tread separation andother tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.

Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may col-
lect on the underbody. If these materials
are not removed, accelerated rusting can
occur on the underbody parts such as
the fuel lines, frame, floor pan and
exhaust system, even though they have
been treated with rust protection.
Thoroughly flush the vehicle underbody
and wheel openings with lukewarm or
cold water once a month, after off-road
driving and at the end of each winter. Payspecial attention to these areas because
it is difficult to see all the mud and dirt. It
will do more harm than good to wet down
the road grime without removing it. The
lower edges of the doors, rocker panels,
and frame members have drain holes
that should not clog with dirt; trapped
water in these areas can cause rusting.
Aluminum wheel maintenance
The aluminum wheels are coated with a
clear protective finish.
 Do not use any abrasive cleaner, pol-ishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch or damage the finish.
 Use only a mild soap or neutral deter- gent, and rinse thoroughly with water.
Also, be sure to clean the wheels after
driving on salted roads. This helps pre-
vent corrosion.
 Avoid washing the wheels with high- speed car wash brushes.
 Do not use any acid detergent. It may damage and corrode the aluminum
wheels coated with a clear protectivefinish.WARNING
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow for-
ward speed.

EMISSION CONTROL SYSTEM
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Service Passport
in your vehicle.
Your vehicle is equipped with an emis- sion control system to meet all emission
regulations. There are three emission control sys-
tems 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 rec-
ommended that you have your vehicle
inspected and maintained by an author-
ized HYUNDAI dealer in accordance with
the maintenance schedule in this manu-al. Caution for the Inspection and
Maintenance Test (With Electronic
Stability Program (ESP) system)
 To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability
Program (ESP) system off by press-
ing the ESP switch.
 After dynamometer testing is com- pleted, turn the ESP system back on
by pressing the ESP switch again. 1. Crankcase emission control
system
The positive crankcase ventilation sys-
tem is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase. This system supplies
fresh 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 valveinto the induction system.
2. Evaporative emission control system
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.

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 con-
trolled by the Engine Control Module
(ECM); when the engine coolant temper-
ature is low during idling, the PCSV clos-
es 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. 3. Exhaust emission control
system
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could affect
its performance, safety or durability and
may even violate governmental safety
and emissions regulations.
In addition, damage or performance
problems resulting from any modification
may not be covered under warranty.
Engine exhaust gas precautions (car- bon monoxide)
 Carbon monoxide can be present with other exhaust fumes. Therefore, if you
smell exhaust fumes of any kind inside
your vehicle, have it inspected and
repaired immediately. If you ever sus-
pect exhaust fumes are coming into
your vehicle, drive it only with all the
windows fully open. Have your vehicle
checked and repaired immediately.
WARNING - Exhaust
Engine exhaust gases contain car-
bon monoxide (CO). Though color-
less and odorless, it is dangerousand could be lethal if inhaled.
Follow the instructions on this
page to avoid CO poisoning.

Maintenance
 Do not operate the engine in confinedor closed areas (such as garages) any
more than what is necessary to move
the vehicle in or out of the area.
 When the vehicle is stopped in an open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to draw
outside air into the vehicle.
 Never sit in a parked or stopped vehi- cle for any extended time with the
engine running.
 When the engine stalls or fails to start, excessive attempts to restart the
engine may cause damage to theemission control system.Operating precautions for catalytic
converters (if equipped)
Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
 Use only UNLEADED FUEL for gaso- line engine.
 Do not operate the vehicle when there are signs of engine malfunction, such
as misfire or a noticeable loss of per-
formance.  Do not misuse or abuse the engine.
Examples of misuse are coasting withthe ignition off and descending steep
grades in gear with the ignition off.
 Do not operate the engine at high idle speed for extended periods (5 minutesor more).
 Do not modify or tamper with any part of the engine or emission control sys-
tem. All inspections and adjustments
must be made by an authorized
HYUNDAI dealer.
 Avoid driving with a extremely low fuel level. Running out of fuel could cause
the engine to misfire, damaging the
catalytic converter.
Failure to observe these precautionscould result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void your
warranties.
WARNING - Fire
A hot exhaust system can ignite
flammable items under your vehi-
cle. Do not park, idle, or drive the
vehicle over or near flammable
objects, such as grass, vegetation,
paper, leaves, etc.

Diesel Particulate Filter (if equipped)
The Diesel Particulate Filter (DPF) sys-
tem removes the soot emitted from the
vehicle.
Unlike a disposable air filter, the DPF
system automatically burns (oxidizes)
and removes the accumulated soot
according to the driving condition. In
other words, the active burning by engine
control system and high exhaust gas
temperature caused by normal/high driv-
ing condition burns and removes the
accumulated soot.
However, if the vehicle continues to be
driven at low speed for a long time, the
accumulated soot may not be automati-
cally removed because of low exhaust
gas temperature. In this particular case,the amount of soot is out of detection
limit, the soot oxidation process by
engine control system may not happen
and the malfunction indicator light may
blink. When the malfunction indicator light
blinks, it may stop blinking by driving the
vehicle at more than 60km/h (37 mph) orat more than second gear with 1500 ~
2000 engine rpm for a certain time (for
about 25 minutes). If the malfunction indicator light contin-
ues to blink in spite of the procedure,
please visit an authorized HYUNDAI
dealer and check the DPF system.
If you continue to drive with the malfunc-
tion indicator light blinking for a long
time, the DPF system can be damaged
and fuel consumption can worsen.
CAUTION
- Diesel Fuel
(if equipped with DPF)
It is recommended to use the regu- lated automotive diesel fuel fordiesel vehicle equipped with the
DPF system.
If you use diesel fuel including highsulfur (more than 50 ppm sulfur) and unspecified additives, it cancause the DPF system to be dam-
aged and white smoke can be emit-ted.
