of either the generator or electrical
charging system.
If the warning light comes on while the
vehicle is in motion:
1. Drive to the nearest safe location.
2. With the engine off, check the genera- tor drive belt for looseness or break-
age.
3. If the belt is adjusted properly, a prob- lem exists somewhere in the electrical
charging system. Have an authorized
HYUNDAI dealer correct the problem
as soon as possible.

D150320ACM
Malfunction indicator lamp(MIL) (check engine light)
This indicator light is part of the Engine
Control System which monitors various
emission control system components. If
this light illuminates while driving, it indi-
cates that a potential problem has been
detected somewhere in the emission
control system.
This light will also illuminate when the
ignition switch is turned to the ON posi-
tion, and will go out in a few seconds
after the engine is started. If it illuminates
while driving, or does not illuminate when
the ignition key is turned to the ON posi-
tion, take your vehicle to your nearest
authorized HYUNDAI dealer and have
the system checked.
Generally, your vehicle will continue to be
drivable, but have the system checked by
an authorized HYUNDAI dealer promptly.

ESC (Electronic Stability
Control) indicator
The ESC indicator will illuminate when
the ignition switch is turned ON, but
should go off after approximately 3 sec-
onds. When the ESC is on, it monitors
the driving conditions. Under normal driv-
ing conditions, the ESC indicator will
remain off. When a slippery or low trac-
tion condition is encountered, the ESC
will operate, and the ESC indicator will
blink to indicate the ESC is operating.
But, if the ESC system malfunctions the
indicator illuminates and stays on. Take
your vehicle to an authorized HYUNDAI
dealer and have the system checked.
ESC OFF indicator
The ESC OFF indicator will illuminate
when the ignition switch is turned ON,
but should go off after approximately 3
seconds. To switch to ESC OFF mode,
press the ESC OFF button. The ESC
OFF indicator will illuminate indicating
the ESC is deactivated.
DBC (Downhill brake con-trol) indicator (if equipped)
The DBC indicator will illuminate when
the DBC button is pressed and the sys-
tem is on. When driving down a steep hill
at a speed under 22 mph (35 km/h), the
DBC will operate and the DBC indicator
will blink to indicate the DBC is operating.
If the red indicator illuminates, the DBC
system may have malfunctioned. Take
your vehicle to an authorized HYUNDAI
dealer and have the system checked.
CAUTION
Prolonged driving with the Emission Control SystemMalfunction Indicator Light illumi-nated may cause damage to theemission control systems which could effect drivability and/or fueleconomy.
CAUTION
If the Emission Control SystemMalfunction Indicator Light illumi-nates, potential catalytic converterdamage is possible which couldresult in loss of engine power. Have the Engine Control System inspect-ed as soon as possible by anauthorized HYUNDAI dealer.

Driving your vehicle
Remember, your vehicle does notrequire extended warm-up. After the
engine has started, allow the engine to
run for 10 to 20 seconds prior to plac-
ing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warm-up period.
Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in too
high a gear resulting engine bucking. If
this happens, shift to a lower gear.
Over-revving is racing the engine
beyond its safe limit. This can be avoid-
ed by shifting at the recommended
speeds.
Use your air conditioning sparingly. The air conditioning system is operat-
ed by engine power so your fuel econ-
omy is reduced when you use it.
Open windows at high speeds can reduce fuel economy.
Fuel economy is less in crosswinds and headwinds. To help offset some of
this loss, slow down when driving in
these conditions. Keeping a vehicle in good operating con-
dition is important both for economy and
safety. Therefore, have an authorized
HYUNDAI dealer perform scheduled
inspections and maintenance.
WARNING - Engine off dur-
ing motion
Never turn the engine off to coast
down hills or anytime the vehicle is
in motion. The power steering and
power brakes will not function
properly without the engine run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect. In
addition, turning off the ignition
while driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury or
death.

What to do in an emergency
TIRE PRESSURE MONITORING SYSTEM (TPMS)
(1) Low tire pressure telltale / TPMS malfunction indicator
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.) As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure. Under-inflation also reduces
fuel efficiency and tire tread life, and
may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is combined with
the low tire pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the system
may not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
nate tires and wheels allow the
TPMS to continue to function proper-
ly.

Maintenance
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
G050100AUN
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the car is being
driven in severe conditions, more fre-
quent oil and filter changes are required.
G050200AUN
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically for
proper tension and adjusted as neces-
sary.
G050300AFD
Fuel filter (cartridge)
A clogged filter can limit the speed at
which the vehicle may be driven, damage
the emission system and cause multiple
issues such as hard starting. If an exces-
sive amount of foreign matter accumu-
lates in the fuel tank, the filter may
require replacement more frequently.
After installing a new filter, run the engine
for several minutes, and check for leaks
at the connections. Fuel filters should be
installed by an authorized HYUNDAI
dealer.
G050400AFD
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have
an authorized HYUNDAI dealer replace
any damaged or leaking parts immedi-
ately.
G050600AUN
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap is
correctly replaced.

B230104AUN
Bright-metal maintenance
To remove road tar and insects, use a
tar remover, not a scraper or other
sharp object.
To protect the surfaces of bright-metal parts from corrosion, apply a coating of
wax or chrome preservative and rub to
a high luster.
During winter weather or in coastal areas, cover the bright metal parts with
a heavier coating of wax or preserva-
tive. If necessary, coat the parts with
non-corrosive petroleum jelly or other
protective compound.
G230105AUN
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 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. Pay
special 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 doors, rocker panels, and
frame members have drain holes that
should not be allowed to clog with dirt;
trapped water in these areas can cause
rusting.
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
G270000AFD
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Owner’s
Handbook & Warranty Information book-
let 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 car
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 Control (ESC) system)
To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability Control
(ESC) system off by pressing the
ESC switch.
After dynamometer testing is com- pleted, turn the ESC system back on
by pressing the ESC switch again.
G270100AUN
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 valve
into the induction system.
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, preventing the escape of
fuel vapors into the atmosphere.)
G270201AUN
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.
G270202AUN
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.

Maintenance

Do not operate the engine in confined
or 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 the
emission control system.G270303CFD
Operating precautions for catalyticconverters (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 with
the 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 minutes
or 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 very low fuel level. If you run out of gasoline, it could
cause the engine to misfire and result
in excessive loading of the catalytic
converter.
Failure to observe these precautions
could 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, vegeta-
tion, paper, leaves, etc.
The exhaust system and catalytic system are very hot while the
engine is running or immediately
after the engine is turned off. Keep
away from the exhaust system
and catalytic, you may get burned.
Also, do not remove the heat sink
around the exhaust system, do
not seal the bottom of the vehicle
or do not coat the vehicle for cor-
rosion control. It may present a
fire risk under certain conditions.
