TENANCE" .
NOTE:
The air conditioner filter caution label is located inside the glove box door.
REPLACEMENT PROCEDURES
1. Remove the glove box assembly. Refer to IP-10, "INSTRUMENT PANEL ASSEMBLY" .
2. Compress the air conditioner filter (1) downward while sliding it
to the RH side of the vehicle to release the upper pawl.
3. Move the bottom of air conditioner filter (1) upward as shown to
release the bottom tab, then remove it.

REFRIGERANT LINES
Revision: June 20062007 Versa
CHECKING PROCEDURE
To prevent inaccurate or false readings, make sure there is no refrigerant vapor, shop chemicals, or cigarette
smoke in the vicinity of the vehicle. Perform the leak test in calm area (low air/wind movement) so that the
leaking refrigerant is not dispersed.
1. Turn engine OFF.
2. Connect a suitable A/C manifold gauge set to the A/C service ports.
3. Check if the A/C refrigerant pressure is at least 345 kPa (3.45 bar, 3.52 kg/cm
2 , 50 psi) above 16°C. If
less than specification, recover/evacuate and recharge the system with the specified amount of refriger-
ant.
NOTE:
At temperatures below 16°C, leaks may not be detected since the system may not reach 345 kPa (3.45
bar, 3.52 kg/cm
2 , 50 psi).
4. Perform the leak test from the high-pressure side (compressor discharge a to evaporator inlet f) to the
low-pressure side (evaporator drain hose g to shaft seal k). Refer to MTC-82, "
Components" . Perform a
leak check for the following areas carefully. Clean the component to be checked and move the leak
detected probe completely around the connection/component.

Compressor
Check the fitting of high- and low-pressure flexible hoses, relief valve and shaft seal.

Condenser
Check the fitting of high-pressure flexible hose and pipe, refrigerant pressure sensor.

Liquid tank
Check the refrigerant connection.

Service valves
Check all around the service valves. Ensure service valve caps are secured on the service valves (to
prevent leaks).
NOTE:
After removing A/C manifold gauge set from service valves, wipe any residue from valves to prevent
any false readings by leak detector.

Cooling unit (Evaporator)
With engine OFF, turn blower fan on “High” for at least 15 seconds to dissipate any refrigerant trace in
the cooling unit. Wait a minimum of 10 minutes accumulation time (refer to the manufacturer’s recom-
mended procedure for actual wait time) before inserting the leak detector probe into the drain hose.
Keep the probe inserted for at least 10 seconds. Use caution not to contaminate the probe tip with
water or dirt that may be in the drain hose.
5. If a leak detector detects a leak, verify at least once by blowing compressed air into area of suspected
leak, then repeat check as outlined above.
6. Do not stop when one leak is found. Continue to check for additional leaks at all system components.
If no leaks are found, perform steps 7-10.
7. Start engine.
8. Set the heater A/C control as follows;
a. A/C switch: ON
b. Mode control dial position: VENT (Ventilation)
c. Intake door lever position: Recirculation
d. Max. cold temperature
e. Fan speed: High
9. Run engine at 1,500 rpm for at least 2 minutes.

INSPECTION
When parking brake lever is operated with a force of 196 N (20 kg-f,
44 lb-f), make sure parking brake lever stroke is within the specified
number of notches. (Check it by listening and counting ratchet
clicks.)
COMPONENTS INSPECTION

Make sure that the mounting conditions (looseness, backlash, etc.) of each component are normal.

Check the following:
–Device assembly for bends, damage and cracks. Replace if any damage is noted.
–Cables and equalizer for wear and damage. Replace if any damage is noted.
–Parking brake switch. Replace if it does not work correctly.
ADJUSTMENT
1. Remove console mask cover. Refer to IP-22, "Removal" .
2. Engage parking brake lever, then lift up the end of the trim on
the lever to access the adjusting nut.
3. Insert a deep socket wrench onto adjusting nut. Rotate adjusting
nut to fully loosen cable, and then release parking brake lever.
4. Depress the foot brake about 10 times and adjust the rear shoe clearance.
CAUTION:
Be sure to securely depress the foot brake.
5. Rotate brake drum to make sure that there is no drag.
6. Adjust parking brake cable with the following procedure.
a. When replace parking brake cable, operate parking brake lever with a force of 490 N (50 kg-f, 110 lb-f)
about 10 times.
b. Engage parking brake lever, then lift up the end of the trim on the lever to access the adjusting nut.
c. Rotate adjusting nut to adjust parking brake lever stroke using a deep socket wrench.
d. Operate parking brake lever with a force of 196 N (20 kg-f, 44 lb-f), make sure the parking brake lever
stroke is within the specified number of notches. (Check it by listening and counting ratchet clicks.)
e. Make sure that there is no drag on rear brake with parking brake lever completely released.
7. Install console mask. Refer to IP-22, "
Removal" . Number of notches : 8 - 9
