628 If Something Happens; Air Suspension In Locked Mode - Volvo FM Handbook

628 If something happens

Air suspension in locked mode

If there is a fault, the air suspension may go into the
locked mode. This disconnects the automatic ride
height.
To adjust the height
1 Control both sides at the same time
In the driving position, both sides are controlled at the
same time. The air in the bogie axle's bellows is
adjusted at the same time as the air in the drive axle is
adjusted.
2 Use the axle switch to select the axle to be adjusted:
• M1 for the front axle.
• M2 for both front and rear axles.
The air in the bogie axle's bellows is adjusted at the
same time as the air in the drive axle is adjusted.
• M3 for rear axle.
The air in the bogie axle's bellows is adjusted at the
same time as the air in the drive axle is adjusted.
Note!
The vehicle should be taken to the
workshop as soon as possible, but
can be used in the mean time.
