OPERATION
DUAL switch Turns left and right ventilation temperature separately control (switch indicator) between ON
⇔
OFF each time.
 When DUAL switch indicator is ON, the driver side and passenger side temperatures can each be set independently.
 When DUAL switch indicator is OFF, the driver side outlet and setting temperature is applied to both
sides.
 Left and right ventilation temperature separately control is cancelled by turning the DEF mode ON.
NOTE:
When front air conditioning system is in the OFF position, left and right ventilation temperature sepa-
rately control can be selected only while front air conditioning system state (when MODE switch is
pressed) is indicated on the display.
Fan switch (UP/DOWN) Blower fan speed is manually controlled with these switches. Seven speeds are available for manual
control (as shown on the display screen)
NOTE:
 When fan switch is pressed while front air conditioning system is in OFF, front air conditioning sys-
tem is activated. (Compressor control state returns to the previous state before front air condition-
ing system OFF.)
 When fan switch is pressed while front air conditioning system is in automatic control (“AUTO” is
indicated), automatic control is released (“AUTO” turns OFF).
FRE switch  Air inlet is selected to fresh air intake (FRE) by pressing this switch.
- FRE indicator: ON
- REC indicator: OFF
 When FRE indicator is ON, pressing the FRE switch for approximately 1.5 seconds or more, and
then the FRE and REC switch indicators blink twice and the system is switched to the automatic
control.
NOTE:
When front air conditioning system is in the OFF position, air inlet can be selected.
MODE switch Selects air outlet sequentially from VENT
⇒ B/L ⇒ FOOT ⇒ D/F ⇒ VENT each time.
NOTE:
 When front air conditioning system is in the OFF position, air outlet can be selected.
 When MODE switch is pressed while front air conditioning system is in automatic control (“AUTO” is indicated), automatic control is released (“AUTO” turns OFF).
OFF switch  Turns front air conditioning system OFF.
 When front air conditioning system turns OFF, air inlet and air outlet become the automatic control.
REC switch  Air inlet is selected to fresh air intake (REC) by pressing this switch.
- REC indicator: ON
- FRE indicator: OFF
 When REC indicator is ON, pressing the REC switch for approximately 1.5 seconds or more, and
then the FRE and REC switch indicators blink twice and the system is switched to the automatic
control.
NOTE:
 When front air conditioning system is in the OFF position, air inlet can be selected.
 When MODE switch and DEF switch is in the D/F or DEF position, air inlet cannot be selected to recirculation (REC).
Temperature control dial
(driver side)  Selects set temperature within a range between 18.0
°C (60 °F) – 32.0 °C (90 °F) at a rate of 0.5 °C
(1.0 °F) each time the dial is rotated.
- Clockwise rotation: Set temperature increases.
- Counterclockwise rotation: Set temperature decreases.
NOTE:
When front air conditioning system is in the OFF position, set temperature can be selected only while
front air conditioning system state (when MODE switch is pressed) is indicated on the display.

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interv iew to document the facts and conditions when the noise occurs and any
customer comments. Refer to INT-11, "
Diagnostic Worksheet". This information is necessary to duplicate the
conditions that exist when the noise occurs.
 The customer may not be able to provide a detailed description or the location of the noise. Attempt to obtain
all the facts and conditions that exist when the noise occurs (or does not occur).
 If there is more than one noise in the vehicle, perform a diagnosis and repair the noise that the customer is
concerned about. This can be accomplished by performing a test drive with the customer.
 After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so that the customer, service advis er, and technician use the same language when describing
the noise.
 Squeak – (Like tennis shoes on a clean floor) Squeak characteristics include the light contact / fast movement / brought on by road conditions / hard sur-
faces = high-pitched noise / softer surfaces = low-pitched noises / edge to surface = chirping
 Creak – (Like walking on an old wooden floor) Creak characteristics include firm contact / slow mo vement/twisting with a rotational movement / pitch
dependent on materials / often brought on by activity.
 Rattle – (Like shaking a baby rattle) Rattle characteristics include fast repeated contact / vi bration or similar movement / loose parts/missing clip
or fastener / incorrect clearance.
 Knock – (Like a knock on a door) Knock characteristics include hollow sounds / someti mes repeating / often brought on by driver action.
 Tick – (Like a clock second hand) Tick characteristics include gentle contacting of light materials / loose components / can be caused by driver
action or road conditions.
 Thump – (Heavy, muffled knock noise)
Thump characteristics include softer knock / dull sounds often brought on by activity.
 Buzz – (Like a bumblebee) Buzz characteristics include high frequency rattle / firm contact.
 Often the degree of acceptable noise level varies depending upon the person. A noise that a technician may
judge as acceptable may be very irritating to a customer.
 Weather conditions, especially humidity and temperat ure, may have a great effect on noise level.
