2. Slide disconnector in axial direction of piping, and stretch garter spring with tapered point of disconnector.
3. Slide disconnector farther so that inside diameter of garter spring becomes larger than outside diameter of
female-side piping flare. Then male-side piping can be disconnected.
INSTALLATION
1. Clean piping connection points, and insert male-side piping into female-side piping.
2. Push inserted male-side piping harder so that female-side piping flare stretches garter spring.
3. If inside diameter of garter spring becomes larger than outside diameter of female-side piping flare, garter
spring seats on flare. Then, it fits in between male-side piping cage and female-side piping flare to anchor
piping connection point.
NOTE:
When garter spring seats on flare, and fits in between male-side piping cage and female-side piping flare,
it clicks.
CAUTION:

Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping
straight in axial direction.

Insert piping securely until a click is heard.

After piping connection is completed, pull male-side piping by hand to make sure that connec-
tion does not come loose.
NOTE:
One-touch joint connection is used in points below.

Low-pressure flexible hose to low-pressure pipe 1 (O-ring size: 16)

High-pressure flexible hose to condenser (O-ring size: 12)

High-pressure pipe 1 to high-pressure pipe 2 (O-ring size: 8)

High-pressure pipe 1 to condenser (O-ring size: 8)

AIR CONDITIONER CONTROL
Revision: 2007 April2007 M35/M45
REAR TEMPERATURE CONTROL SWITCH

Increases or decreases the set temperature.

A temperature for the rear seat with respect to a set temperature for the front seat can be adjusted by
operating switch.

Rear temperature control switch allows to select a temperature every 0.5°C (1°F) in the 18°C (60°F) to
32°C (90°F) range.

When the DUAL switch is ON, temperature for the rear seat changes keeping the temperature difference
between two front seats. [e.g. When lowering the set temperature for the rear seat 1°C (2°F) by operating
rear control switch at a set temperature of 25°C (77°F) for the driver’s seat and 26°C (79°F) for the pas-
senger’s seat, the set temperature for the driver’s seat and passenger’s seat lower 1°C (2°F) and become
24°C (75°F) for the driver’s seat and 25°C (77°F) for the passenger’s seat.]
NOTE:
A set temperature for the rear seat is tied to a set temperature for the passenger’s seat. Therefore, a set
temperature for the rear seat changes in conjunction with a set temperature for the passenger’s seat
(When the set temperature of front seats are independent).
Fail-Safe FunctionNJS000G9

SQUEAK AND RATTLE TROUBLE DIAGNOSIS
Revision: 2007 April2007 M35/M45
TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.
