Maintenance
Blade inspectionInformation
Hot wax in market may be used in
automatic car washes. However, it is
known to make it difficult to clean the
windshield.
Contamination of either the wind-
shield or the wiper blades with for-
eign substances may undermine the
effects of the windshield wipers.
Common contamination sources are
insects, tree sap, and hot wax treat-
ments used in some car washes.
When the blades do not properly
wipe off, clean the window and
blades with a good-quality cleaner or
mild detergent. Then, thoroughly
wash them with clean water.
Do not use gasolines, kerosene,
paint thinner, or other solvents on
or near the wiper blades to pre-
vent damage.
Blade replacement
When the wipers no longer ade-
quately clean, the blades may be
worn out or cracked. Then, replace-
ment is required.
To prevent damage to the wiper
arms or other components, do not
attempt to manually move the
wipers.
The use of a non-specified wiper
blade could result in wiper mal-
function and failure.
Front windshield wiper blade
For your convenience, move the
windshield wiper blades as illustrat-
ed.
Turn off the engine.
Fully raise the wipers by setting the
wiper lever in the single wiping
(MIST) position less than 20 sec-
onds.

because the headlamps or interior
lights remain on, while the vehicle
is not in use), slowly recharge it
(trickle) for 10 hours.
When the battery is gradually dis- charged due to high electric load,
while the vehicle is in use,
recharge it at 20-30A for 2 hours.
Battery recharging by vehicle
After jump-starting from a good bat-
tery, run the engine for 20-30 min-
utes in either the idle or driving
modes, before turning off the engine.

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.

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.
