Maintenance
High-pressure washing
When using high-pressure wash-ers, make sure to maintain suffi-
cient distance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
Do not spray the camera, sensors or its surrounding area directly with
a high pressure washer. Shock
applied from high pressure water
may cause the device to not oper-
ate normally.
Do not bring the nozzle tip close to boots (rubber or plastic covers)or
connectors as they may be dam-
aged if they come into contact with
high pressure water.
Do not use any high-pressure noz- zles, which induce either one-direct
water stream or water swirling. Water washing in the engine
compartment including high
pressure water washing may
cause the failure of electrical cir-
cuits located in the engine com-
partment.
Never allow water or other liq- uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them. Matte paint finish vehicle
(if equipped)
Automatic car wash which uses
rotating brushes should not be
used as this can damage the sur-
face of your vehicle. A steam
cleaner which washes the vehicle
surface at high temperature may
result the oil to adhere and leave
stains that is difficult to remove.
Use a soft cloth (e.g. microfiber
towel or sponge) when washing
your vehicle and dry with a
microfiber towel. When you hand
wash your vehicle, you should not
use a cleaner that finishes with
wax. If the vehicle surface is too
dirty (sand, dirt, dust, contami-
nant, etc.), clean the surface with
water before washing the car.

Maintenance
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 sole-
noid 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 evap-
orated 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 per-
formance.
When the engine starts or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission system.
Vehicle modifications
This vehicle should not be modi-
fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
If you use unauthorized electronic devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
Engine exhaust (carbon monox-ide) precautions
Carbon monoxide can be present
with other exhaust fumes. If you
smell exhaust fumes of any kind in
your vehicle, drive with all the win-
dows fully open. Have your vehicle
checked and repaired immediately.
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.
WARNING

Maintenance
Do not operate the engine in con-fined 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 vehicle 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.Operating precautions for cat-alytic converters (if equipped)
CALIFORNIA PROPOSITION 65
WARNING
Engine exhaust and a wide vari-
ety of automobile components
and parts, including compo-
nents found in the interior fur-
nishings in a vehicle, contain or
emit chemicals known to the
State of California to cause can-
cer and birth defects and repro-
ductive harm. In addition, cer-
tain fluids contained in vehicles
and certain products of compo-
nent wear contain or emit chem-
icals known to the State of
California to cause cancer and
birth defects or other reproduc-
tive harm.
WARNING
The exhaust system and cat-
alytic converter are very hot
during and immediately after
the engine has been running. To
avoid SERIOUS INJURY or
DEATH:
Do not park, idle, or drive the
vehicle over or near flamma-
ble objects, such as grass,
vegetation, paper, leaves, etc.
A hot exhaust system can
ignite flammable items under
your vehicle.
Keep away from the exhaust
system and catalytic convert-
er or you may get burned.
Also, Do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle, and do not coat
the vehicle for corrosion con-
trol. It may present a fire risk
under certain conditions.
WARNING

7-86
Maintenance
Your vehicle is equipped with a cat-
alytic converter emission control
device. To prevent damage to the
catalytic converter and to your vehi-
cle, take the following precautions:
Use only UNLEADED FUEL for gasoline engines.
Do not operate the vehicle when there are signs of engine malfunc-
tion, such as misfire or a noticeable
loss of performance.
Do not misuse or abuse the engine. Examples of misuse are
coasting with the engine off and
descending steep grades in gear
with the engine 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 con-
trol system. All inspections and
adjustments must be made by an
authorized HYUNDAI dealer.
Avoid driving with extremely 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.

2: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econ-
omy by reducing the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure
in everyday driving, but in a year’s time, they can offer significant cost and energy savings.Lubricant Volume Classification

Recommended SAE Viscosity
Number
Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing or draining any lubricant.
This is especially important in
dusty or sandy areas and when
the vehicle is used on unpaved
roads. Cleaning the plug and
dipstick areas will prevent dirt
and grit from entering the
engine and other mechanisms
that could be damaged.
CAUTION
Engine oil viscosity (thickness) has an effect on fuel economy and cold
weather operating (engine start and engine oil flowability). Lower viscosity
engine oils can provide better fuel economy and cold weather performance,
however, higher viscosity engine oils are required for satisfactory lubrication
in hot weather. Using oils of any viscosity other than those recommended
could result in engine damage. When choosing an oil, consider the range of
temperature your vehicle will be operated in before the next oil change.
Proceed to select the recommended oil viscosity from the chart.

*1: For better fuel economy, it is recommended to use the engine oil
of a viscosity grade SAE 5W-20/API Latest (ILSAC Latest).
However, if the engine oil is not available in your country, select
the proper engine oil using the engine oil viscosity chart.
An engine oil displaying this American Petroleum Institute(API) Certification Mark
conforms to the International Lubricant Specification Advisory Committee (ILSAC). It
is recommended to only use engine oils that uphold this API Certification Mark.
