● If the technician needs to use medical electronic devices, for example, the automatic electronic defibrillator, then he can not operate in the vehicle, otherwise, the function of the device may be effected by the strong magnetic components.

Regular Charge Precaution

Warning:

● If the technician uses medical devices such as cardiac pacemaker, cardiovertor, cardiac defibrillator, etc., the function of the devices must be checked before starting a normal operation.

● In a regular charging operation, electronic medical devices may be effected by the electromagnetic waves. Technicians using a medical device, such as cardiac pacemaker, cardiovertor, cardiac defibrillator , etc., should not enter the passenger cabin(including baggage cabin).

Communication equipment operation precautions

● Technicians using a electronic medical device, such as cardiac pacemaker, cardiovertor, cardiac defibrillator, etc, should keep a safe distance from the communication equipment.

● The electromagnetic wave of the remote intelligent terminal may effect the function of medical electronic devices such as cardiac pacemaker,cardioverter, cardiac defibrillator, , etc.

●The electromagnetic wave of the remote intelligent terminal may effect the function of devices when technicians using a electronic medical device, such as cardiac pacemaker, cardiovertor, cardiac defibrillator, etc. The possible effect of remote intelligent terminal on electronic medical device must be inspected by the manufacture of the electronic medical device .

Key points inspection before maintenance

The high-voltage system may automatically operate. Please confirm the remote air conditioning and fixed-time charging haven’t been set before the maintenance.

Attention：

● If the remote air conditioning and fixed time charging have been set, the high pressure system will automatically operate even if the switch is in closed state.

Precautions concerning the auxiliary restraint system "airbag" and "seat belt pretension"

Auxiliary restraint system “airbag” and “seat belt pretension” can be used together with the front seat safety belt which can reduce the hurt on the driver and front row passenger in a collision Auxiliary restraint system includes safety belt and airbags for driver and co-driver. Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual.

Warning:

In order to avoid accidents, please obey the following instructions:

In order to avoid failure of the auxiliary restraint system which may increase the possibility of casualty in an collision All the reparation can only be operated by the JAC authorized distributors.

Nonstandard reparation of the auxiliary restraint system, including nonstandard disassembly and assembly, may accidentally activate the auxiliary restraint system and cause personal injury. Disassembly of the airbag module refers to the chapter of “airbag system”.

● Do not use any electrical test devices to test any circuit of the auxiliary restraint system except operations described in the service manual. The wire harness and connectors of the auxiliary restraint system should use yellow color or orange color.

Precautions when using power tools (air or electric) and hammers.

● When the power switch is at ON position, do not use power tools or the hammer to operate on the sensor accessory areas which are close to the airbag diagnose sensor and other sensors of the airbag system. Violent vibrations may activate these sensors, ignite the airbag and cause serious damage.

● When using a power tool or a hammer, rotate the key to LOCK gear, plug off the negative terminal of the 12V lead-acid storage battery, wait for at least one minute, then start the maintenance.

Precaution for Removing 12V Battery

When removing the 12V battery, turn the power switch to “ON” at first, and then to “OFF”.

Note:

● Even if the key is at the “LOCK” gear, the automatically charging function of 12V battery may still launch.

● After the key rotates from “ON” to “LOCK”, the the automatically charging function of 12V battery can not launch.

Basic inspection

1 Check whether the coolant is filled up. If not ,please fill up. Please refer to the chapter “maintenance-cooling system”.

Warning:

Do not open the filling port of the expansion kettle assembly when the temperature of the coolant is very high in case of hurt caused by spilt coolant.

2 Start the cooling pump and touch the shell of the pump to check whether there is continuous vibration. If not, please repair or replace it.
