Check the deformation of cylinder block top face with a ruler or a feeler gauge.

所用的加大尺寸活塞应按具有最大孔径的气缸来确定。

The oversize piston used should be determined by the cylinder with maximum diameter of hole.

镗孔尺寸=活塞外径＋活塞与气缸之间的间隙 [(0.02-0.04)mm]-[研磨余量0.02mm]

Boring size= Piston outer diameter ＋ clearance between piston and cylinder [(0.02- 0.04) mm] - [grinding allowance 0.02 mm]

front air bag and seat belt pre-tensioner can reduce damages to driver and the passengers in the front row when the vehicle encounters danagers or impacts.

具体请参见本手册 “辅助约束系统”和 “安全带”章节。

For details, see this manual “Supplemental Restraint System” and Section “Seat Belt”.

为防止SRS不起作用而造成人员伤亡，在因碰撞而导致安全气囊弹开后应由郑州日产授权的服务站进行维修。

In order to avoid casualities caused by SRS malfunction, for air bag bounced off due to crashes, the service should be provided by service stations with ZNA authorization.

不正确的维修，包括对不正确的拆卸和安装，可能导致安全气囊自行弹开对人体造成伤害。

Incorrect maintenance, including incorrect removal and installation of SRS, may cause air bag to bounce off automaticlly and result in damages to people.

因此在拆卸安装气囊螺旋线圈和气囊模块时参照 “辅助约束系统”章节。

Therefore, when removing and installing airbag spiral coil and airbag module, see Section "Supplemental Restraint System".

在点火开关在 “ON”或发动机运转状态下，不要使用风动或电动工具对气囊模块或其他气囊传感器附近部件进行检查。

Neither detect airbag module or other parts near airbag sensor with pneumatic or electric tools when the ignition switch is in "ON"postion or the engine runs.

当使用风动或电动工具时，需要将点火开关打到 “OFF”，拔掉蓄电池连接线， 3分钟后再进行检查作业。

When using pneumatic or electric tools, place the ignition switch in "OFF" position, unplug battery cable, and perform inspections after 3 minutes.

该操作程序只适用于装备智能钥匙系统和NATS(日产防盗系统)的车辆。

The operation procedure only applies to vehicles equipped with intelligent key system and NATS (Nissan Anti-Theft System).

在点火钥匙置于 “LOCK”位置时，断开蓄电池线后，才能拆卸和安装控制模块。

When the ignition key is in "LOCK" position, the removal and installation of control module can only be performed after disconnecting battery cable.

若出现DTC码，依照自诊断结果进行故障诊断。

If DTC code is displayed, perform trouble diagnosis according to self-diagnosis result.

装备智能钥匙系统和NATS系统的车型，锁芯中安装有电动转向装置。

For vehicles with intelligent key system and NATS, electric steering device is installed into the key cylinder.

因此，如果蓄电池线断开或蓄电池无电，方向盘将会锁死，无法转动。

Therefore, the steering wheel will lock and cannot rotate if the battery cable is disconnected or the battery is dead.

使用点火钥匙或普通钥匙，将点火开关打至 “ACC”位置。

Use ignition key or common key to turn ignition switch to “ACC” position.

断开蓄电池线，方向盘锁将会持续开锁，方向盘将会转动。

Disconnect batter cable, the steering wheel lock will be unlocked continuously, and the steering wheel will rotate.

 (此时，方向盘锁机构处于激活状态。

 (At this time, the steering wheel lock meachanism is active.

执行CONSULT-III自诊断功能，检查所有控制模块。

Perform CONSULT-III self-diagnosis function to check all control modules.

始终要注意安全工作，不要勉强或不按说明操作。

Always pay attention to safety, do not force or operate without following the descriptions.

有条理地标识并整理解体的零部件，以便于故障排除和重新组装。

Mark and arrange the disassembled component parts in an organized way for easy troubleshooting and reassembly.

如果指定了拧紧顺序，请按指定顺序操作。

If loosening order is specified, please follow the order.

仔细检查发动机机油或发动机冷却液管路有无堵塞。

Carefully check the engine oil or engine coolant lines for clogging.

彻底清除布屑或灰尘等异物。

Completely wipe off foreign materials, like lint or dust.

排尽发动机冷却液后重新加注时，先释放管道中的空气。

When refilling engine coolant after draining it, release air from lines first.
