Auto stop indicator(if equipped)
This indicator will illuminate when the engine enters the Idle Stop mode ofthe ISG (Idle Stop and Go) system.
When the automatic starting occurs, the auto stop indicator on the cluster
will blink for few seconds.
For more details, refer to the ISG (Idle Stop and Go) system in thechapter 5.
Information
When the engine automatically starts
by the ISG system, some warning
lights (ABS/EBD/VDC/VDC OFF)
may turn on for a few seconds.
This happens because of the low bat-
tery voltage. It does not mean the sys-
tem is malfunctioning.
Engine Oil Pressure Warning Light
This warning light illuminates:
Once you set the ignition switch to the ON position.
- It remains on until the engine isstarted.
When the engine oil pressure is low.
If the engine oil pressure is low:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. Turn the engine off and check the engine oil level (For more details,
refer to “Engine Oil” in chapter 7) .
If the level is low, add oil as required.
If the warning light remains on
after adding oil or if oil is not avail-
able, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer as
soon as possible.
Malfunction indicator
lamp (MIL)
(check engine light)
This indicator light is part of theEngine Control System which moni-
tors various emission control system
components. If this light illuminates
while driving, it indicates that a
potential problem has been detected
somewhere in the emission controlsystem. This light will also illuminate when

This warning light illuminates when a
door and the electrical step (for bus)are not closed securely with the igni-
tion in any position.
Fuel filter warning light
This warning light illuminates for 3
seconds after the ignition switch isset to the ON position and then it will
go out. If it lights up while the engine
is running, it indicates that water has
accumulated inside the fuel filter. If
this happens, remove the water from
the fuel filter. For more information,
refer to “Fuel filter” in section 7.
Diesel preheat indica-tor light
The indicator light illuminates amber
when the ignition switch is placed at
the "ON" position. The engine can be
started after the preheat indicator
light goes off. The illuminating time
varies with the water temperature, air
temperature and battery condition.
If the engine were not started within 10 seconds after the pre-
heating is completed, turn the
ignition key once more to the
"LOCK" position, and then to the
"ON" position, in order to preheat
again.
NOTICE
When the fuel filter warning
light is illuminated, engine
power (vehicle speed & idle

DPF (Diesel ParticulateFilter) Warning
Indicator
The Diesel Particulate Filter (DPF)
system removes the soot emitted
from the vehicle.
Unlike a disposable air filter, the DPF
system automatically burns (oxi-
dizes) and removes the accumulated
soot while driving.
However, if the vehicle continues to
be driven in short distance repeated-
ly or at low speed for a long time, the
accumulated soot may not be auto-
matically removed because of low
exhaust gas temperature. In this par-
ticular case, if the amount of soot is
out of detection limit, the DPF warn-
ing indicator ( ) will illuminate. In
order to start the DPF regeneration
and to stop the DPF warning lamp
illuminating, drive the vehicle in a
safety driving circumstance with
more than 60km/h (37 mph) vehiclespeed or with more than secondgear engaged and 1500 ~ 2000
engine rpm for a certain time (for
about 25 minutes). If the DPF warning indicator( )
continues to blink or "check emissionsystem" message comes on in the
cluster in spite of the above proce-
dure, we recommend that the system
be checked by an authorized
HYUNDAI dealer.
If you continue to drive with the indi-
cator light blinking for a long time, theDPF system can be damaged and
fuel consumption can be worsen.
Urea Level Warning
lamp
The urea level warning lamp illumi-
nates, when the urea solution vol-
ume falls below 12% or less of the
tank. Without adding the urea solu-
tion, when the urea solution volume
drops to 6%, urea level warning lamp
will start blinking. When the urea
solution volume drops 4% or under,
both urea level warning lamp and
urea system warning lamp will simul-
taneously blink with limited torque.
When the urea volume falls below
1%, both lamps will stay blinking sta-
tus with limited vehicle speed.
When the urea level warning lamp
illuminates, the urea solution mustbe added.
The urea level warning lamp will still
illuminate with the remaining drivingdistance after replenishment, and
then the lamp will go out after sever-
al minutes driving or after several
minutes ignition on status.

Urea system warninglamp
When the vehicle has critical prob- lems such as incorrect urea replen-
ishment, urea consumption devia-
tion, urea dosing interruption or
EGR(exhaust gas recirculation) sys-tem malfunction, the urea system
warning lamp will start blink with lim-
ited engine torque or vehicle speed.
Engine oil level warn-ing light (if equipped)
The engine oil level warning light illu-
minates when the engine oil level
should be checked.
If the warning light comes on, check
the engine oil level as soon as possi-
ble and add engine oil as required.
Slowly pour the recommended oil lit-
tle by little into a funnel. Use only the specified engine oil.
(Refer to "Recommended lubricantsand capacities" in section 8.)
Do not overfill the engine oil to
ensure the oil level is not above F
mark on the dipstick. Information
 If you travel approximately 50~100 km after the engine warms up, after
adding the engine oil, the warning
light will go off.
 Cycle the ignition from OFF to ON 3 times within 10 seconds, the warn-
ing light will go off immediately.
However, when you turn off the
warning light without adding the
engine oil, the light will come on
again after traveling approximately
50~100 km after the engine warms
up.
If the light comes on continuously
after adding the engine oil and
traveling approximately 50~100
km after the engine warms up, werecommend that the system be
checked by an authorized
HYUNDAI dealer. Even if this light doesn't come on
after the engine has started, the
engine oil should be checked and
supplied periodically.

gently toward you to spray washer
fluid on the windshield and to run the
wipers 1-3 cycles. Use this function when the wind-
shield is dirty.
The spray and wiper operation will
continue until you release the lever.
If the washer does not work, check
the washer fluid level. If the fluid level
is not sufficient, you will need to add
appropriate non-abrasive windshield
washer fluid to the washer reservoir.The reservoir filler neck is located in
the front of the engine compartment
on the passenger side.

Driving your vehicle
ENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle,
open the windows immediately.
Do not inhale exhaust fumes.
Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by
asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose.
If you hear a change in the sound of the exhaust or if you drive over something that strikes the underneath side of
the vehicle, we recommend that the system be checked by an authorized HYUNDAI dealer.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the
engine in your garage any longer than it takes to start the engine and back the vehicle out.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the vehicle, be sure to do so only in
an open area with the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn
into the interior.
If you must drive with the tailgate open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher
speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the
windshield are kept clear of snow, ice, leaves or other obstructions.
