ENGINE ASSEMBLY
4. Remove engine mounting insulator (RH) (1), engine mounting
bracket (RH) (2) and engine mounting stay (3).
5. Remove engine mounting through bolt-securing nut (A).
6. Carefully lower jack, or raise lift to remove the engine and the transaxle assembly.
CAUTION:
 Make sure that no part interferes with the vehicle side.
 Before and during this lifting, always check if any harnesses are left connected.
 During the removal, always be careful to prevent the vehicle from falling off the lift due to
changes in the center of gravity.
 If necessary, support the vehicle by setting jack or suitable tool at the rear.
Separation
1. Remove starter motor. Refer to STR-13, "Removal and Installation".
2. Lift with a hoist and separate the engine from the transaxle assembly. Refer to EM-89, "
Exploded View".
INSTALLATION
Installation is in the reverse order of removal.
 Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting insu-
lator.
 Make sure that each mounting insulator is seated properly, and tighten mounting nuts and bolts.
 Tighten engine mounting insulator (RH) bolts in the numerical
order shown.

INSPECTION AFTER INSTALLATION
Inspection for Leaks
 Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-19, "
Fluids and Lubricants".
 Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
 Run engine to check for unusual noise and vibration.
 Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids includ-
ing engine oil and engine coolant.
 Bleed air from lines and hoses of applicable lines, such as in cooling system.
 After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.

porting tools.
CAUTION:
 During the operation, make sure that no part interferes with the vehicle side.
 Before and during this lifting, always check if any harnesses are left connected.
 During the removal operation, always be careful to prevent the vehicle from falling off the lift due
to changes in the center of gravity.
 If necessary, support the vehicle by setting jack or suitable tool at the rear.
 During operation, securely support the engine by placing a piece of wood under the engine oil
pan and transaxle oil pan. Securely support the engine slingers with a hoist.
31. When the engine hoisting is not performed simultaneously, install engine slinger to cylinder head front left
side and rear right side. Refer to EM-207, "
Component".
32. Remove starter motor. Refer to STR-24, "

changes in the center of gravity.
 If necessary, support vehicle by setting a jack or equivalent tool at the rear.
Separation Work
CAUTION:
During the operation, secure the engine by placing a piece of wood under the engine oil pan and tran-
saxle and lift the engine using a suitable tool.

MODE DOOR MOTOR
System DescriptionINFOID:0000000001547404
SYSTEM DESCRIPTION
Component Parts
Mode door control system components are:
 Front air control
 Mode door motor
 In-vehicle sensor
 Ambient sensor
 Sunload sensor
System Operation
The front air control receives data from each of the sensors. When a drive signal is input from front air control
to door motor, a step motor built into the door motor rotates according to the drive signal, and then stops at the
position of target door.
Mode door changes to manual select mode by pressing MODE/DEF switch of the controller. That allows mode
door to be fixed.
Pressing AUTO switch allows automatic control by front air control, and mode door is fixed in the FOOT posi-
tion by pressing OFF switch.
During automatic operation of mode door, mode door position (VENT, B/L, FOOT) is selected according to the
temperature of discharge air calculated by front air control based on the target opening angle of air mix door
and the amount of sunload. And only when ambient temperature is extremely low with the mode door in the
FOOT position, D/F is selected and prevents windshield fogging.

System Operation
Suction opening is basically fixed in the position FRESH when DEF switch, FRE switch, or OFF switch (only at
the time of REC switch OFF) is pressed or when A/C switch is OFF. It is fixed in the position RECIRCULATION
when REC switch is pressed. It is automatically controlled at all other times.
During automatic control of suction opening, any of FRESH, 20% FRESH and RECIRCULATION is selected
according to the target opening angle of air mix door calculated by front air control based on the in-vehicle
temperature, ambient temperature and the amount of sunload.
