concave or other distortions, it is necessary to change with new product.

z When assembling the airbag assemble at the side of driver, it is necessary to pay attention to airbag

wiring harness could not interrupt other parts or be clamped by other parts.

(a) Connect the end.

(b) Connect the joint of airbag.

(c) After assembling the safety airbag assembly at the side

It is necessary to change parts correctly, for they will influence the performance of steering system to incur

running danger.

2. Notes for SRS airbag system

MR7180 equips with SRS (auxiliary protection system), such as safety airbag at the side of driver and

safety airbag at the side of passenger, if repairment does not accord with correct sequence, it might incur

SRS explodes suddenly in repairing term to make heavy accident. Before repairing (including disassem-

Inspection on automobile

1. Check driving belt

(a) Check whether the belt has been abraded too much with eyes, and rope is broken.

If finding any defect, change the driving belt.

Hint: Some light crack at the side of belt rib could be approved, but if belt has any crack from

its rib, it is necessary to change.

2. Exhaust air of power steering system

(a) Check the oil level.

(b) Lift up automobile body, and support it with bracket.

(c) Turn steering wheel.

(1) Turn steering wheel slowly from left and right to bottom for several times when engine extinguishes.

(d) Lay down the automobile.

(e) Start the engine to make it run at idling speed for several minutes.

(f) Rotate steering wheel.

(1) Keep engine at idling speed, and turn the steering wheel from left or right to bottom and keep this

state for 2-3 seconds, then turn it to the other direction for 2-3 seconds.

(2) Repeat (1) for several times.

(g) Engine extinguishes.

(h) Check whether there is any foam or emulsification

phenomenon.

If there is any foam or emulsification phenomenon and

it is necessary to exhaust air second time, it is necessary

to check whether the system has any leakage.

(i) Check the oil level.

3. Check the oil level

(a) Keep automobile horizontal.

(b) Extinguish the engine, and check the oil level of oil stor-

age tank.

If oil level is too low, add oil.

Power steering oil: automatic transmission oil

DEXRON’’ II or III

Hint: check whether the oil level is in the HOT mark

scope of oil storage tank, if oil is cool, check the

oil level is in COLD mark scope.

(c) Start the engine, and keep it at idling speed.

(d) Turn steering wheel from left bottom to right bottom for

several times to make oil temperature increase.

Oil temperature: 80°C
