Maintenance
A vehicle’s electrical system is pro-
tected from a possible electrical
overloading damage by fuses.
This vehicle has 4 fuse panels - two
on the driver’s side, another on the
panel bolster of the passenger's
side, and the other in the engine
compartment.
When any of your lights, acces-
sories, or controls does not operate,
check the appropriate circuit fuse.
When a fuse is out, some elements
may melt inside.
When the electrical system does not
operate, check the fuse panel on the
driver's side first.
Before replacing the fuse, disconnect
the negative battery cable. Always
replace it with a fuse of the same rat-
ing. When the newly-replaced fuse
blows, there may be an electrical
problem. Avoid using any pertinent
systems. Immediately consult an
authorized EQUUS dealer.
Three kinds of fuses are to be used:
a blade type for lower amperage rat-ing, and a cartridge type and a fusiblelink for higher amperage ratings.
Information
The actual fuse, relay panels, and
labels may differ from the equipped
items.

- Fuse replacement
Never replace a fuse with the
one of a different rating.
A higher capacity fuse may cause damage or a fire.
Never use a wire or an alu- minum foil, instead of a prop-
er fuse - even as an emergent
measure. It may damage
extensive wirings and cause a
fire.
WARNING
Do not use a screwdriver or any
other metal object to remove a
fuse. It may cause a short cir-
cuit and damage the system.

puller provided in the panels either
on the driver’s side or the front pas-
senger’s side.
4. Check the removed fuse. When the fuse is out, replace it.
Spare fuses are provided in the
fuse panels in the front passen-
ger's side. (or in the fuse panel of
the engine compartment)
5. Install a new fuse of the same rat- ing, and tightly secure it in the
clips.
When it is loosely fit, consult an
authorized EQUUS dealer.
When you do not have a spare fuse,
use a fuse of the same rating from a
circuit, such as a cigarette lighter fuse,
which may not be needed to drive. When the headlamps or other electri-
cal components do not operate, but
when the fuses are not blown out,
check the fuse panel in the engine
compartment. In case that a fuse is
blown out, it must be replaced.fuse is
blown, it must be replaced.

Maintenance
Waxing
A good coat of wax bars contamina-
tion from the vehicle paint. Maintain a
good coat of wax on your vehicle to
protect it.
Wax the vehicle when the wax polish
vanishes.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster.A spot remover, which removes oil,
tar, and other similar materials, peels
off the wax coating from the finish.
Make sure to re-wax these areas,
even when the rest of the vehicle
does not need be waxed.
Finish damage repair
Deep scratches or stone chips on the
paint must be repaired in a prompt
manner. Any exposed metal area
quickly gets rusty, and repairing it
may cost a lot.
Information
When your vehicle requires any metal
repair or replacement after damage,
make sure the body shop applies anti-
corrosion materials to the parts to be
repaired or to be replaced.
i
Washing the engine compart-
ment with the water of high
pressure is not recommend-
ed. It may fail electrical cir-
cuits, engine and any other
related part, located in the
engine compartment.
Never allow water or other liq- uids to contact with electri-
cal/electronic components
and the air duct. These may
damage them.
CAUTION
Wiping dust or dirt off thebody with a dry cloth will
scratch the finish.
Do not use a steel- or wool- abrasive cleaner, or strong
detergents, which is high in
alkaline or caustic agents on
chrome-plated, or which
anodizes aluminum parts.
This may damage the protec-
tive coating and cause discol-
oration or paint deterioration.
CAUTION

Maintenance07
The emission control system of your
vehicle is covered by a written limited
warranty. Please refer to the Owner’s
Handbook & Warranty Information
booklet for more warranty information.
Your vehicle is equipped with an
emission control system to meet all
applicable emission regulations.
Below are the three emission control
systems.
(1) Crankcase emission control sys-tem
(2) Evaporative emission control sys- tem
(3) Exhaust emission control system
In order to assure the proper opera-
tion of the emission control systems,
it is recommended that you have
your car inspected and maintained
by an authorized EQUUS dealer in
accordance with the maintenance
schedule in this manual.
Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
To prevent a misfiring during a dynamometer test, press the
Electronic Stability Control (ESC)
system OFF.
After a dynamometer test, turn ON the ESC system back.1. Crankcase emission control system
The positive crankcase ventilation
system is to prevent the gas emis-
sion from the crankcase and to
reduce the air pollution. This system
supplies filtered-out, fresh air to the
crankcase through the air intake
hose. Inside the crankcase, the fil-
tered-out air mixes with 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
vapor emission into the atmosphere.
(The ORVR system is designed to
keep the fuel vapors in a canister
while being refueled at the gas sta-
tion, preventing the fuel vapor emis-
sion into the atmosphere.)
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors are
absorbed in the canister, and are
drawn into the engine intake mani-
fold through the purge control sole-
noid valve.

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.
