Safety system of your vehicle02
Even though your vehicle isequipped with the occupant
classification system, never
install a child restraint system
in the front passenger's seat. A
deploying air bag may forcefully
strike a child, resulting in seri-
ous injury or death. Any child
age 12 and under should ride in
a rear seat. Children too big for
a child restraint should use the
available lap/shoulder belts. No
matter what type of a crash
occurs, children of all ages are
safer, when restrained in a rear
seat.
When the "PASSENGER AIR BAG OFF" indicator illumi-
nates with an adult's occupa-
tion in the front passenger's
seat, he/she sits properly (sit-
ting in an upright position,
and sitting on the center of
the seat cushion with their
seat belt fastened, legs com-
fortably extended and their
feet on the floor), have that
person sit in a rear seat.
Do not modify or replace the front passenger's seat. Do not
place or attach any items, such
as a blanket or seat heater, on
the front passenger's seat.
This may adversely affect the
occupant classification sys-
tem.
When the weight load is changed in the front passen-
ger's seat, the PASSENGER
"AIR BAG OFF" indicator may
flash ON and OFF for a few sec-
onds, enabling and disabling
the front passenger's air bag.
(Continued)
(Continued)
Do not sit over a sharp object,such as a tool, in the front
passenger's seat. This may
adversely affect the occupant
classification system.
Do not use an accessory seat cover over the front passen-
ger's seat.
Accident statistics show that children are safer, when
restrained in a rear than in the
front. It is recommended that
all child restraints be secured
in a rear seat, including a rear-
facing infant seat, a forward-
facing child seat and a boost-
er seat
Air bags can be used only once – have an authorized
EQUUS dealer replace the air
bag immediately after a
deployment.
A tiny adult's incorrect seat- ing (i.e. excessively reclining,
leaning toward the door or the
center console, or slanting
forward) may cause a condi-
tion where the advanced front
passenger's air bag system
senses less weight than occu-
pant's the actual weight (when
properly sitting in an upright
position, and sitting on the
center of the seat cushion
with their seat belt fastened,
legs comfortably extended
and their feet on the floor).
This condition may result in
misclassification of an occu-
pant and illumination of the
"PASSENGER AIR BAG OFF"
indicator.WARNING

inside again.
(fresh) Air intake mode
With the (fresh) air intake mode selected, air outside
the vehicle will enter inside
the vehicle, and be heated
or cooled according to the
selected function.
Information
A prolonged period of the heater oper-
ation in the air recirculation mode
(without air conditioning selected)
may cause fogging on the windshield
and side windows, and make the air
stale inside the vehicle.
In addition, a prolonged period of the
air conditioning operation in the air
recirculation mode may make air
excessively dry inside the vehicle.

A prolonged period of the cli- mate control system opera-
tion in the air recirculation
mode may intake damp air,
increase humidity inside the
vehicle, cause fogging on win-
dows and obscure driver's
view.
Do not sleep in a vehicle with the air conditioning or heating
system ON. It may cause seri-
ous harm or death due to oxy-
gen deficiency and hypother-
mia.
A prolonged period of the cli- mate control system opera-
tion in the air recirculation
mode may cause drowsiness,
sleepiness or loss of vehicle

Air Quality System (AQS)
The air intake from outside can be
automatically controlled. Press the
button to activate the AQS.
When setting in the AQS mode, the
system automatically senses out-
door air pollutants and minimizes the
air pollutant entering into the vehicle.
However, unpleasant or foul odors
may be still noticeable inside the
vehicle.
Exhaust gas cut-off mode :
The exhaust gas may enter the vehicle
from the outside in the (fresh) air
intake mode. However, with the
exhaust gas cut-off mode selected,
the air intake control automatically
converts to the air recirculation mode
to prevent the exhaust gas from enter-
ing the vehicle.
Information
It should be noted that a prolonged
period of the heater operation in the
air recirculation mode may cause fog-
ging on the windshield and side win-
dows, and make the air stale inside the
vehicle. In addition, a prolonged peri-
od of the air conditioning operation in
the air recirculation mode may make
air excessively dry inside the vehicle.
If the windows are fogged up in
either the air recirculation mode
or the AQS mode, change the air
intake control to the (fresh) air
intake mode or turn the AQS OFF.

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.

For the maximum defrosting effects, set the temperature to be
extreme hot (extreme right) and
set the fan speed in the highest.
When you want warm air near the floor while defrosting or defogging,
set the mode in the floor-defrost
position.
Before driving, clear all snow and ice from the windshield, rear win-
dow, outside rear view mirrors,
and all side windows.
Clear all snow and ice from the hood and air inlet in the cowl grill
to improve heater and defroster
efficiency and to prevent possible
dew condensation on the inside of
the windshield.
Information
If the engine temperature is still cold
after starting, brief warming up of the
engine may be required to warm the
air in the air outlet.
To defog inside windshield
1. Select the desired fan speed.
2. Select the desired temperature.
3. Press the defrost button ( ).
4. The (fresh) air intake mode will beselected automatically.
If the (fresh) air intake mode is not
selected automatically, adjust the
corresponding buttons manually.
If the position is selected, lower
fan speed is adjusted according to
the higher fan speed.

- Windshield heating
Do not set in the or in the
position when operating the
A/C in extremely humid weath-
er. The difference between the
outside and inside tempera-
tures could cause the dew con-
densation on the outer surface
of the windshield, causing loss
of driver's view, serious injury
or death. In this case, set the
knob or the button in the
position and lower the fan
speed.

Auto defogging system (if equipped)
Auto defogging reduces the probabil-
ity of the dew condensation on the
inside of the windshield by automati-
cally sensing the moisture.
The auto defogging system operates
when the heater or the A/C is ON.
This indicator illuminates
when the auto defogging
system senses the mois-
ture on the inside of the
windshield and operates.
If it is humid inside the vehicle, the
automated steps operate as follows:
If auto defogging system does not
defog the window in the step 1 (fresh
air intake mode), the steps 2 and 3
will be followed.
Step 1 : (fresh) air intake mode
Step 2 : Operating the A/C
Step 3 : Blowing air toward the wind- shield
Step 4 : Increasing air flow toward the windshield The auto defogging system automat-
ically activates in certain conditions.
However, if you want to turn OFF the
auto defogging system, press the
front defroster button 4 times within 2
seconds while pressing the AUTO
button. The front defroster indicator
will flash 3 times to notify the system
cancellation. To restart the auto
defogging system, follow the proce-
dures mentioned above.
If the battery is disconnected or dis-
charged, it resets to the auto defog-
ging status.Information
When the A/C is turned ON and the
(fresh) air intake mode is selected by
the auto defogging system, and when
you try to turn OFF the A/C and select
the air recirculation mode, the indica-
tor will just flash 3 times, the A/C will
not be turned OFF, and the air recir-
culation mode will not be selected.
Do not remove the sensor cover
on the upper end of the driver's
side windshield. Damage to sys-
tem parts could occur and may
not be covered by your vehicle
warranty.

Driving your vehicle- Driving under the influence of alcohol or drugs
DUI (driving under the influ-
ence) is dangerous. DUI is the
number one contributor to the
highway death toll each year.
Even a small amount of alcohol
will affect your reflexes, percep-
tions and judgment. Driving
under the influence of drugs is
as dangerous as or more dan-
gerous than driving under the
influence of alcohol.
You are much more likely to
have a serious accident if you
drive under the influence of
alcohol or drug. After you drink
alcohol or take drugs, do not
drive. Do not ride in a passen-
ger's seat when a driver drinks
or takes drugs.
Have a designated driver in
your group or call a cab.
WARNING
When you park or pull over the vehicle with the engine
ON, be careful not to depress
the accelerator pedal for a
long period of time. It may
overheat the engine or
exhaust system and cause
fire.
When you make a sudden stop or rapidly turn the steer-
ing wheel, any loose objects
may toss about inside the
vehicle and interfere with the
pedal operation, possibly
causing an accident. Keep all
things in the vehicle safely
stored.
If you are not concentrated while driving, it may cause an
accident. Be careful when
operating controls such as
the audio or heater. It is
always the driver's responsi-
bility to be attentive to the
driving safety.

Maintenance
Check all the cooling system hoses
and heater hoses. If necessary,
replace any swollen or deteriorated
one. The coolant level should
be between F and L marks
on the coolant reservoir,
when the engine is cool.
When the coolant level is low, add
distilled (deionized) water. Bring up
the level to F, but do not overfill.
When frequent additions are
required, have an authorized
EQUUS dealer inspect your cooling
system.
Recommended engine coolant
When adding coolant, use the deionized water, distilled water or
soft water. Never add hard water in
the coolant. An improper coolant
mixture may result in serious mal-
function or engine damage.
The engine parts are made of alu- minum and must be protected by
an ethyleneglycol-based coolant
from any corrosion and freezing.
DO NOT USE alcohol or methanol coolant, nor mix them with the
authorized coolant. Do not use the solution of which
the antifreeze portion is above
60% or below 35%. This may
reduce the solution effects.
Mix the water and antifreeze in the half-and-half ratio. This solution will
work in most situations.
For the proper mixture ratio, refer to
the following table.
Information
The half-and-half ratio solution of
water and antifreeze is effective at a
temperature of -31°F (-35°C) and
higher.
