push the lever upward and
release it with the lever in the
OFF position. The wipers will
operate continuously if the

part of the wiper operation system,
the wiper may operate in the LO
mode regardless of the wiper switch
position. In this case, have your
vehicle checked by an authorized

Air conditioning system operation
tips
When the vehicle is parked underthe direct sunlight in hot weather,
open the windows for a short time
to expel the hot air inside from the
vehicle.
To reduce the dew condensation on the inside of the windows on
rainy or humid days, lower the
humidity inside the vehicle by
operating the A/C system.
During the A/C operation, you may occasionally notice a slight
change in the engine speed, as
the A/C compressor cycles. This is
a normal condition.
Test the A/C system every month only for a few minutes to maximize
the system performance.
After the inside temperature becomes sufficiently cool, change
the air intake control from the air
recirculation mode to the (fresh)
air intake mode.
When operating the A/C system, you may notice clear water drip-
ping (or even puddling) from the
passenger side of the vehicle. This
does not indicate a system failure.
The air recirculation mode of the A/C provides the maximum cool-
ing. However, a prolonged period
of the A/C operation in this mode
may make the air stale inside the
vehicle.
While operating the A/C system, you may occasionally notice the
dew condensation because of the
rapid cooling process and humid
air intake. This does not mean
there is not a system failure.
Climate control air filter
The climate control air filter is
installed behind the glove box to filter
out dust or other pollutants that come
into the vehicle from the outside
through the heating and air condi-
tioning systems.
If dust or other pollutants accumulate
in the filter over a period of time, the
air intake volume may decrease,
resulting in the dew condensation
inside the windshield even when set-
ting in the (fresh) air intake mode. In
this case, have the climate control air
filter replaced by an authorized
EQUUS dealer.
Information
• Replace the filter every 15,000 miles(24,000 km) or once a year. If the car
has been driven in severe conditions
such as dusty or rough roads, more
frequent air conditioner filter
inspections and changes are
required.
• When the air flow rate suddenly decreases, have the system checked
by an authorized EQUUS dealer.

Before entering vehicle
• Be sure that all windows, outsidemirror(s), and outside lights are
clean.
Check the condition of the tires.
Check underneath the vehicle for any leakage sign.
Make sure there are no obstacles behind, when you intend to drive
backwards.
Necessary inspections
Fluid levels, such as engine oil,
engine coolant, brake fluid, and
washer fluid should be checked on a
regular basis, at exact intervals.
Further details are provided in the
chapter 7, "Maintenance".
Before starting
Close and lock all doors.
Check the seat position, so all con-trols are easily accessible.
Adjust the inside and outside rearview mirrors.
Make sure that all lights operate.
Check all gauges.
Check the operation of warning lights when the Engine Start/Stop
button is turned ON.
Release the parking brake and make sure the brake warning light
goes OFF.
For safe operation, make sure you
are familiar with your vehicle equip-
ment and operation.
