Convenient features of your vehicle
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.

Driving your vehicle
- ENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes may be extremely dangerous. When, at any time, you
smell exhaust fumes inside the vehicle, immediately open the windows.
• Do not inhale exhaust fumes.Exhaust fumes contain carbon monoxide, the colorless, odorless gas that
may cause unconsciousness and death by asphyxiation.
The exhaust system should be checked whenever the vehicle is raised to
change the oil or for any other purpose. If you notice a change in the sound
of the exhaust system or if you drive over something that strikes the vehicle
underneath, have the exhaust system checked as soon as possible by an
authorized EQUUS dealer.
Letting the engine idle in a garage, even with the garage door open, is haz-
ardous. Never run the engine in your garage any longer than it takes to start
the engine and move out the vehicle.
Avoid idling the engine for a prolonged period of time with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period of time with people
inside the vehicle, idle the engine in an open area with the air control in the
(fresh) air intake mode and the fan operating at a high speed. Thus, fresh air
can be taken into the interior.
When you need to drive with the trunk lid open because of the object you carry,
make sure the followings:
1. Close all windows.
2. Open side vents.
3. Set the air intake control in (fresh) air intake mode, the air flow directed toward "Floor" or "Face," and the fan at a high speed.
To assure proper ventilation, clear snow, ice, leaves or other substances from
the air inlet just in front of the windshield.
WARNING
Engine exhaust and a wide variety of automobile components and
parts, including components found in the interior furnishings in a
vehicle, contain or emit chemicals known to the State of California to
cause cancer and birth defects and reproductive harm. In addition,
certain fluids contained in vehicles and certain products of compo-
nent wear contain or emit chemicals known to the State of California
to cause cancer and birth defects or other reproductive harm.
