*1: When the A/T selector lever position is N position, the engine start condition is different according to the vehicle speed.
At vehicle speed of 5 km/h or less, the engine can start only when the brake pedal is depressed.
At vehicle speed of 5 km/h or more, the engine can start even if the brake pedal is not depressed. (It is the same as “Engine stall
return operation while driving”.)
*2: When the A/T selector lever position is any position other than P position and when the vehicle speed is 5 km/h or more, the engine
stop condition is different.
Press and hold the push-button ignition switch for 2 seconds or more. (When the push-button ignition switch is pressed for too short
a time, the operation may be invalid, so properly press and hold to prevent the incorrect operation.)

On-Vehicle InspectionNDS000EA
APPEARANCE AND NOISE INSPECTION
Check the propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.
PROPELLER SHAFT VIBRATION
If vibration is present at high speed, inspect propeller shaft runout first.
1. Measure propeller shaft runout at runout measuring point by
rotating final drive companion flange with hands. For measuring
point, refer to PR-4, "
Propeller Shaft Runout Measuring Point" .
2. If runout still exceeds specifications, separate propeller shaft at
final drive companion flange; then rotate companion flange 90,
180, 270 degrees and install propeller shaft.
3. Check runout again. If runout still exceeds specifications,
replace propeller shaft assembly.
4. Check the vibration by driving vehicle.

Removal and InstallationNDS000EC
REMOVAL
1. Remove engine undercover with a power tool.
2. If necessary, remove heat bracket.
3. Remove the three way catalyst (right bank) with a power tool. Refer to EX-3, "
EXHAUST SYSTEM" .
4. Put matching marks onto propeller shaft flange yoke and final
drive companion flange.
CAUTION:
For matching marks, use paint. Do not damage propeller
shaft flange and companion flange.
5. Remove the propeller shaft fixing bolts.
6. Remove propeller shaft from the front final drive and transfer.
INSPECTION
Inspect propeller shaft runout at measuring point. If runout
exceeds specifications, replace propeller shaft assembly. For
measuring point, refer to PR-4, "
Propeller Shaft Runout Measur-
ing Point" .
As shown in the figure, while fixing yoke on one side, check axial
play of joint. If outside the standard, replace propeller shaft
assembly.
Check propeller shaft for bend and damage. If damage is
detected, replace propeller shaft assembly.
CAUTION:
Do not disassemble joints.
INSTALLATION
Note the following, install in the reverse order of removal.
Align matching marks to install propeller shaft to final drive com-
panion flange, and then tighten to specified torque. Refer to PR-
4, "Components" .
CAUTION:
Do not reuse the bolts.
After assembly, perform a driving test to check propeller shaft
vibration. If vibration occurred, separate propeller shaft from
final drive or transfer. Reinstall companion flange after rotating it
by 90, 180, 270 degrees. Then perform driving test and check
propeller shaft vibration again at each point.
