Safety measures for operation on the air bag system:

1. The operation includes inspection, fitting and maintenance, which is to be carried

out by professional personnel.

2. Diagnosing instruments are generally used in inspection.

Voltmeter or other testers with open wire are forbidden.

3. The battery negative pole should be removed prior to operation on the air bag.

Proceed to the following work after it has been removed for at least 90 seconds.

Nobody is allowed on vehicle after the air bag system has been reconnected to the

batteries.

4. The air bag should be refitted immediately after being taken out of its

packaging.

5. If the operation is interrupted, the air bag should be put into its packaging, so

that it is at all times under control.

6. When holding the air bag, the inflating device should

point outward and never

hold the cable.

7. When disassembling the air bag and the components to be installed, put them

on the base seat surface with the cut welding line facing upward. Don’t put the

steering column with the steering wheel on the floor.

(II) Hairspring

Disassembling and installing

Chery A15 Maintenance Manual

1.

First remove the air bag according

the hairspring and the steering column.

Remove the hairspring.

Installing procedures are in the

reversed order. Note that the lower

terminal of the hairspring will be on the

lower part when it is connected to the

steering column. The hairspring can’t be

turned unless by pressing the lug which is

pointed with the arrow in the figure. The

Chery A15 Maintenance Manual

Control device

Remove the battery negative pole.

Remove the air bag device terminal,

which is located on the intake below instrument

panel. Remove the air intake beside the

air bag control device under the auxiliary

instrument panel.

Loosen the set nuts between the air

bag control and the bracket. Installing

procedures for the control device are in

the reversed order. Nobody is allowed

in the cab when reconnecting the batteries.

Use of the air bag device

A gas generator which hasn’t been exploded is dangerous. In order to avoid

possible accident, before vehicle is scrapped or service period of air bag explosion

component has been expired, the air bag device should be caused to explode. This is

very important for the reason that exposed part of human body may be damaged when

sudden explosion occurs.

The air bag should be caused to explode within the vehicle, with the vehicle door

closed and at a distance at least 10m away from the vehicle. Cause the air bag on

driver side to explode.

When causing the gas generator on air bag lid on driver side to explode, remove it

from the steering wheel. Remove only the two hexagonal set bolts on this position.

Connect the special type cable. Replace this unit on steering wheel with spare part.

Tighten the hexagonal set bolts.

The exploded air bag may be discarded as common waste vessel. If the vehicle

has been scrapped, leave the air bag on it.
