Maintenance
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 to prevent
the evaporated fuel from getting into
the engine. After warming up the
engine in a normal driving condition,
the PCSV opens to introduce evapo-
rated fuel to the engine.
3. Exhaust emission control system
The Exhaust Emission Control
System is highly effective in control-
ling exhaust emissions, while main-
taining good vehicle performance.
Vehicle modifications
This vehicle should not be modi-
fied. Modification of your vehicle
may affect its driving performance,
safety or durability. This even may
violate safety and emissions regu-
lations of the government.
In addition, damage or perform-
ance problems, which is resulted in
due to any modification, may not
be covered by a warranty.
Use of unauthorized electric devices may cause abnormal vehi-
cle operation, wire damage, bat-
tery discharge and a fire.
Be careful not to damage your
vehicle by using an unauthorized
electric device.
Engine exhaust gas precautions (carbon monoxide)
Carbon monoxide is present in
exhaust fumes. Therefore, when
you smell exhaust fumes of any
kinds, inside your vehicle, immedi-
ately have it inspected and
repaired. When you suspect
exhaust fume emission into your
vehicle, drive the vehicle only when
all windows are fully opened.
Immediately have your vehicle
checked and repaired immediately.
- Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and is lethal, if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.
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.
CALIFORNIA PROPOSI- TION 65 WARNING

Recommended SAE viscosity number
Always be sure to clean the filler-plug area, drain plug, or dipstick before
checking or draining any lubricant. This is especially important in dusty
or sandy areas or after driving on an unpaved road. The practice to
maintain the plug and dipstick areas clean prevents dirt and grit from
entering the engine or the other mechanisms, which may be damaged.
Engine oil viscosity (thickness) effects the fuel economy and the driving in a
cold weather (engine start and engine oil flow). Engine oils of the lower vis-
cosity improves the fuel economy and driving performance in a cold weather.
However, engine oil of the higher viscosity are required for sufficient lubrica-
tion in a hot weather.
Using oils out of the recommended viscosity may damage the engine. When
choosing an oil, consider the range of temperature, in which your vehicle
drives. Find the recommended oil viscosity from the chart.

1. For the better fuel economy, it is recommended to use the engine oil
of a viscosity grade SAE 5W-20 (API Service SM / ILSAC GF-4).
However, when this engine oil is unavailable in your country, select
a proper engine, using the engine oil viscosity chart.
