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.

Maintenance07
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, with the engine running,
for more than a short period of time,
adjust the ventilation system (as
needed) to draw the outside air into
the vehicle.
Never sit inside a parked or stopped vehicle for any extended period of
time, while the engine is running.
When the engine stalls or fails to start, excessive attempts to restart
the engine may damage the emis-
sion control system.
Operating precautions for cat-alytic converters (if equipped)
Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, you must observe the fol-
lowing precautions:
Use only the UNLEADED FUEL for
gasoline engines.
Do not drive the vehicle when there are signs of engine malfunction,
such as misfiring or noticeable
under-performing.
Do not misuse or abuse the engine. Examples of the engine
misusage are coasting and
descending on a steep slope with
the ignition in the OFF position.
Do not idle the engine at a high speed for an extended period of
time (5 minutes or more).
Do not modify any part of the engine or the emission control sys-
tem. All inspections and adjust-
ments must be done by an author-
ized EQUUS dealer.
Avoid driving with a low level of fuels. When your vehicle runs out
of gasoline, it may misfire the
engine or result in excessive load-
ing of the catalytic converter.
Failure to observe these precautions
may damage the catalytic converter
as well as your vehicle. Additionally,
such actions may void your war-
ranties.
- Fire
A hot exhaust system can
ignite flammable items under
your vehicle. Do not park, idle,
or drive the vehicle over or
near flammable objects, such
as grass, vegetation, paper,
leaves, etc.
The exhaust system and cat- alytic system are very hot
while the engine is running or
immediately after the engine
is turned off. Keep away from
the exhaust system and cat-
alytic; you may get burned.
Also, do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle or do not coat the
vehicle for corrosion control.
It may present a fire risk under
certain conditions.
WARNING

To assure the proper engine and powertrain performance and durability, use
only lubricants of the proper quality.
The proper lubricants also promote engine efficiency, leading to a better fuel
economy.
These lubricants and fluids are recommended for use in your vehicle.
*1Refer to the recommended SAE viscosity numbers on the next page.

2Engine oils, labeled as Energy Conserving Oil, are now available. Along with other
additional benefits, they contribute to fuel economy 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 significantly reduce costs and
deliver energy savings.
*
3When the API service SM engine oil is not available in your country, you are able to use API service SL.

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.
