SERVICE INFORMATION

PRECAUTIONS

Precaution for Battery Service INFOID:0000000003109916

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interference between the window edge and the vehicle when the door is opened/closed. During normal operation, the window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic window function will not work with the battery disconnected.

Service Notice or Precaution INFOID:0000000001646112

• Never reuse CSC (Concentric Slave Cylinder) body and CSC tube. Because CSC slides back to the original position every time when removing transmission assembly. At this timing, dust on the sliding parts may damage a seal of CSC and may cause clutch fluid leakage. Refer to CL-11, "

• Do not reuse transmission oil, once it has been drained.

• Check oil level or replace oil with vehicle on level ground.

• During removal or installation, keep inside of transmission clear of dust or dirt.

• Check for the correct installation status prior to removal or disassembly. If matching marks are required, be certain they do not interfere with the function of the parts they are applied to.

• In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tightening sequence is specified, observe it.

• Be careful not to damage sliding surfaces and mating surfaces.

• Do not hold control lever housing to prevent bushing of control lever housing from deformation when moving transmission assembly.

17. Put the shift knob in the correct position as the following indicates. a. When tightening shift knob, if shift knob comes to the proper

position within 1/2 turn from the position at which resistance begins to be felt, tighten it 1 more turn to set it in the proper position.

b. If it takes more than 1/2 turn from the position at which resis-

tance begins to be felt, tighten it to set it in the proper position.

CAUTION:

• Do not adjust the knob with loosing.

• After adjusting to the regular position, until 30 minutes pass, do not operate the shift intensely such as screwing or turning the shift knob to opposite direction since a locking sealant because stiff.

INSPECTION AFTER INSTALLATION

After installing, confirm the following items:

• When control lever assembly is shifted to each position, make sure there is no binding or disconnection in each boot.

• When shifted to each position, make sure there is no noise, binding, and backlash. Especially when control lever assembly is shifted to 5th, 6th without pressing downward, check for binding.

• When control lever assembly is shifted to 1st, 2nd side and 5th, 6th side, confirm control lever assembly returns to neutral position smoothly.

• In any position other than reverse, confirm that control lever assembly can be pressed downward.

• With control lever assembly pressed downward, confirm that it can be shifted to reverse.

• When shifted from reverse to neutral position, confirm control lever assembly returns to neutral position smoothly with spring power.

• Without control lever assembly pressed downward, confirm that it cannot be shifted to reverse.
